Suggested December 2023 How To Unbrick Or Restore Samsung Galaxy S3 Gt
Well, what we can do now is try to restore your Galaxy S3 back to stock using a firmware so that all bad partitions on the device are fixed and it doesn’t bootloops and restarts normally.
And well, depending on what you were trying to do, and more importantly how, it could either be soft-bricked or hard-bricked — in latter case, as sad as it is, you maybe out of luck, man!
What’s Hard-brick and Soft-brick?
Even though rare, and when you are like set to be doomed, your Galaxy S3 might get hard-bricked. In which case, the Galaxy S3 won’t boot into download mode — it won’t respond to key combinations you are trying to make it to boot normally or to download or recovery mode.
Hard-brick results in one dead Android device. Yes, it’s sick, and worrying. You may have to look for a JTAG service locally; the person with good knowledge of that may be able to revive it. Oh, you can also try using USB Jig (look on ebay, perhaps!) to reboot the Galaxy S3 into download mode, but it may or may not work!
Hard-brick is rare, it may happen only when power supply gets disturbed of computer and/or Android device when something is being installed/updated on the device. Or, when you totally mis-do things totally recklessly. That’s why you have to be very careful with even the easiest steps.
Let’s see soft-brick now. Normally, a rick is a soft-brick, which means your device isn’t completely dead, that it is just not able to boot normally and gets stuck somewhere. And, download mode is working.
How to identify bricked Galaxy S3?
If your Android device can boot into download mode, then it means it’s a soft-brick. If it cannot, then it’s hard-bricked.
Cases of soft-brick:
Bootloop: Your Galaxy S3 is not restarting properly and gets stuck at logo, and reboots again and again on it. Mostly occurs when you flash something bad.
Corrupted but working: Your Galaxy S3 can’t power On, but is entering the Download mode and/or Recovery mode on pressing the key combinations. That is, it’s responding to key combos, at the least.
Any other case: As it doesn’t matter what happened, as long as you can access Download mode using the key combos specified in the unbrick Galaxy S3 guide below, you’re good — no reasons to worry!
Just install the firmware using the guide below and your Galaxy S3 shall be up and running coolly soon enough! you must be able to enter download using the key combinations specified in the guide below.
Cases of Hard-brick:
Well, if you can’t enter download mode using the key combinations specified in the guide below, you got a worry — your device is hard-bricked. You can’t repair it yourself unless you are able to reboot it into download mode.
You can try USB Jig to enter Download mode but there is no guarantee it would work. Your last hope is JTAG: find a local service provider who can us the JTAG for you and revive your dead hard bricked Galaxy S3. You can use Google to buy JTAG and try it yourself but we don’t recommend it at all, at it requires the skills of a knowledgeable person in Electronics.
Let’s see now how to unbrick or restore or fix a bricked Galaxy S3.
How to Restore Samsung Galaxy S3 to Unbrick and Fix it
Warranty may be void of your device if you follow the procedures given on this page.
You only are responsible for your device. We won’t be liable if any damage occurs to your device and/or its components.
SAMSUNG GALAXY S3 GT-I9300 OFFICIAL JELLY BEAN 4.3 FIRMWARE
Before you begin with guide instructions below, make sure your android device is adequately charged — at least 50% battery of the device.
STEP 0: CHECK DEVICE MODEL NO.
To make sure your device is eligible with this, you must first confirm its model no. in ‘About device’ option under Settings. Another way to confirm model no. is by looking for it on the packaging box of your device. It must be GT-I9300!
Do not use the procedures discussed here on any other Galaxy S3 (including the Galaxy S3 variant at T-Mobile, Sprint, US-Cellular, AT&T, Verizon and other International LTE variants) or any other device of Samsung or any other company. You have been warned!
STEP 1: BACKUP YOUR DEVICE
Back up important data and stuff before you start playing around here as there are chances you might lose your apps and app-data (app settings, game progress, etc.), and in rare case, files on the internal memory, too.
For help on Backup and Restore, check out our exclusive page on that linked right below.
► ANDROID BACK UP AND RESTORE GUIDE: APPS AND TIPS
STEP 2: INSTALL LATEST DRIVER
You must have proper and working driver installed on your windows computer to be able to successfully flash stock firmware on your Samsung Galaxy S3. In case you’re not sure, follow the link below for a definitive guide for installing driver for your Galaxy S3 on your computer.
► SAMSUNG GALAXY S3 DRIVERS INSTALLATION GUIDE
STEP 3: INSTALLATION INSTRUCTIONSDOWNLOADS
Download the Odin zip file and firmware file given below. Transfer both Odin and firmware file to a separate folder on your computer just to keep things tidy.ODIN ZIP FILE FIRMWARE ZIP FILE STEP-BY-STEP GUIDE
Important Note: Backup important files stored on internal SD card of your device, so that in case a situation arises requiring you to do a factory reset after flashing stock firmware, which might delete internal sd card too, your files will remain safe on PC.
Extract/Unzip the Odin zip file, Latest Odin3 v3.09.zip on your computer (using 7-zip free software, preferably) to get this file: Odin3 v3.09.exe
Extract/Unzip the Firmware zip file, I9300XXUGMK6_I9300OXAGMK6_BTU.zip on your computer (using 7-zip free software, preferably) to get this file: I9300XXUGMK6_I9300OXAGMK6_I9300XXUGMK6_HOME.tar.md5
Move the friwmare file, tar.md5, in the same folder in which you extracted Latest Odin3 v3.09.zip (Just for your convenience, that is). So, now you’ll have the following files in that folder:
Disconnect the Galaxy S3 from PC if it is connected.
Boot your Samsung Galaxy S3 into Download Mode:
Power off your phone first and wait for 6-7 seconds after display is off
Press and hold these 3 buttons together until you see Warning! screen: Volume Down + Power + Home
If you don’t get the Added! message, here are some troubleshooting tips:
Make sure you have installed driver for Galaxy S3 as said above in ‘Before you begin..’ section.
If you have already installed driver, then uninstall them and reinstall back.
Connect using a different USB port on your PC.
Try a different USB cable. The original cable that came with your phone should work best, if not, try any other cable that’s new and of good quality.
Reboot phone and PC and then try again.
Load the firmware file (extracted in Step 1) into Odin as instructed below:
Now in the Option section of Odin, make sure that Re-Partition box is unchecked. (Auto Reboot and F. Reset Time boxes remain checked, while all other boxes remain unchecked.)
Double check the above two steps.
If you see FAIL message instead of the PASS in Odin’s top left box, that’s a problem. Try this now: disconnect your Galaxy S3 from PC, close Odin, remove phone’s battery and put it back inside in 3-4 seconds, open Odin and then repeat from Step 3 of this guide again.
Also, If device is Stuck at setup connection or on any other process, then too, try this: disconnect your S3 from PC, close Odin, remove phone’s battery and put it back inside in 3-4 seconds, open Odin and then repeat from Step 3 of this guide again.
Your suggestions and queries, if any, are most welcomed!

The best Android tablets
Samsung Chromebook Pro review
Samsung Galaxy Tab S4 review: This is not a laptop
Samsung just recently announced its latest convertible-styled Chromebooks, which now offer support for full blown Android apps – opening a gate that was once closed to them, so it’s especially intriguing how things have turned out. Now that by itself should make anyone question Samsung’s decision to launch its new Galaxy Tab S3, which comes almost two years after its predecessor. In that time, we’ve seen a radical shift in how consumers perceive tablets.
The Tab S3 is competing against other Windows 10 tablets and convertibles in the same price bracket, as well as these cheap Chromebooks and Apple’s iPad Pro tablets. So, do we really need another high-end Android tablet? Find out in our full Samsung Galaxy Tab S3 review!
The biggest change to the display, however, is that it now features high dynamic range – that fancy HDR tech allows it to adjust details, contrast, and color saturation to give videos more of that cinematic vividness. From what we saw in our demo time during MWC 2023, it looked really great in how the contrast in the shadows were adjusted to draw out more details in the scene. However, it’s something you’ll witness with content produced in HDR – so existing videos without HDR won’t necessarily see improvements.
The quad speakers deliver crisp-sounding audio perfect for videos
That being said, there’s no arguing that the Tab S3 is remarkable for media consumption, since it’s been bred for that purpose. In complementing the HDR-enabled display, Samsung pairs the experience with quad speakers; two sets of speakers positioned on both edges of the tablet in landscape. They’re tuned by AKG by Harman, delivering crisp-sounding audio perfect for videos – giving it the necessary stereo effect. But despite reaching a top output of 75.4 dB, it doesn’t sound more potent than the speakers in the iPad Pro.
Indeed, the Tab S3 handles most of the basic functions of a tablet, but it still stumbles when trying to juggle around more processor-intensive stuff. We see it happen when using Nougat’s baked-in side-by-side multitasking, as there are still some instances when it freezes momentarily. Most actions result in fluid movements, like surfing the web or using the S Pen in a painting app, but there are still times when hiccups do occur with the performance. It’s not frequent, thankfully, but that does make us wonder if it’s the software that’s the culprit.
The benchmark tests reveal it’s very much a powerhouse, in the elite class as you’d expect, rivaling the scores achieved by today’s top-end smartphones. One area that Samsung places a lot of emphasis on is gaming, thanks in part to the Vulkan graphics API engine – allowing it to deliver a solid gaming experience. The emphasis on gaming is especially noticeable in Samsung’s Game Launcher, which dishes up tools that allow gamers to do things like record their footage; without impacting its graphics processing performance in the process.
Aside from a few aesthetic changes to the design of the tablet, such as its quad speakers, everything else is pretty much in its usual position. Just like before, the power button and volume keys are located along the right edge of the tablet, along with the microSD card slot. Around the bottom, we have a 3.5 mm headphone jack with the newer USB Type-C connection port, which is positioned offset from the center.
Samsung has increased the battery capacity to a 6,000 mAh cell, up from its predecessor capacity of 5,870 mAh. That’s a very miniscule upgrade, which results in barely any difference with its battery life performance on a real-world basis. It’s average to say the least, which means that it’s something that would benefit from nightly charges.
Battery life on the Tab S3 is average, to say the least
In our benchmark testing, it topped out at 6 hours and 41 minutes with web surfing – while video watching lasted a minute more at 6 hours and 42 minutes. That’s really nothing worth bragging about, since they’re very average in comparison to other devices we’ve tested. However, it’s at least speedy enough with its recharging via its fast charging technology, taking only a mere 168 minutes to fully charge. That’s impressive given the capacity we’re dealing with, as most smartphones can take nearly the same time to accomplish.
Owners of Samsung’s Galaxy smartphones will be able to continue having access to certain things on their phones while using the Tab S3, thanks in part to Samsung Flow, which allows us to share files wirelessly with the phone – and even respond to message and view notifications. We actually prefer using the old SideSync app, which essentially virtualizes the phone in all of its glory on the tablet. You basically have a window that displays the contents of the phone, so you can do things like send text messages, receive phone calls, and much more!
There still aren’t enough tablet-optimized apps on Android yet
The biggest flaw with the software in our opinion, which is a big deal breaker when you think about it, is how the platform lacks optimized apps meant to be used on tablets. We’re not even talking about third party apps here, just because some of the native apps still don’t support landscape orientation – so it’s an annoyance that forces us to place it in portrait.
Going back to third party apps, this is the disparity that allows the iPad Pro to expose Android’s weakness. There are a handful of popular apps that still don’t properly adjust dynamically in landscape, like Instagram for example. Due to this lack of tablet optimized apps, it really doesn’t help out the tablet’s cause – making it feel like we’re dealing with a very huge phone, as opposed to a tablet. And when you consider that some Chromebooks now offer support for Android apps, it lessens the value of owning an Android tablet nowadays.
The Galaxy Camera has been launched recently, and the Android development community has already been able to root it, and will no doubt be coming up with custom ROMs and other hacks for the device, extending its functionality and maybe camera capabilities further.
But in all the time one spends tinkering around on the device, there is often a necessity to restore back to stock firmware if something messes up the device, or if someone simply wants to go back to stock in order to claim warranty or get rid of any hacks they may have applied, which is why we’ve made a simple guide that will help you flash back to a stock firmware on your Galaxy Camera if the need arises.
There’s a firmware for every country and region, so just follow the guide below and you’ll have a fully restored and working Galaxy Camera in no time.
The procedure described below is only for the Samsung Galaxy Camera, model number EK-GC100. Do not try it on any other device, not even on another model of the same device.
The methods and procedures discussed here are considered risky, so try them out at your own risk, and make sure to read each step carefully before attempting anything. We will not be held responsible if anything goes wrong.
How to Restore Galaxy Camera to Stock Firmware
Extract the file downloaded in step 3 on the computer to obtain a file with a .tar.md5 extension. The file name may also end at .tar, which is normal. This is the actual firmware file that we need to flash on the camera.
Extract the contents of the Odin3_v3.04.zip file to a folder on your computer.
Turn off the camera and wait for it to shut down completely.
Then, hold down the Volume Down + Camera + Power buttons together till the screen turns on to boot into download mode. If you get a Warning! screen instead, press theVolume Up button to boot into download mode.
Connect the camera to PC now. You should get the message “Added !!” under Odin’s message box in the bottom left.
If you don’t get this message, make sure you installed drivers correctly (using Kies or directly) as given in step 2. If it still doesn’t work, try changing to another USB port on the computer and also use the USB ports on the back if you have a desktop PC.
Important! Do not make any other changes in Odin except selecting the required files as given in step 11. Leave all other options as they are. Make sure Re-Partition check box is not selected.
What do if Odin gets stuck or doesn’t do anything: If ODIN gets stuck on setup connection or at any stage of this process after you’ve hit the Start button, and doesn’t seem to be doing anything, or if upon completion of the process you get a FAIL message (with red background) in ODIN, do this: disconnect the camera from the PC, close ODIN, remove battery for 4-5 seconds, re-insert it, turn camera on in Download mode again, and do the procedure again from Step 9.
[Important] What to do if the camera doesn’t boot: After you get the PASS message and the camera reboots, the camera might get stuck at the booting animation. If that happens, perform the following steps to make it boot. Remember that these steps will wipe your personal data like contacts, apps, messages, etc. If your canera has already booted, you can stop reading the guide here, your camera has been restored successfully:
Boot to recovery mode — for which, first power off camera (by removing battery and reinserting it), wait for 5-6 seconds, and then press and hold Volume Up + Camera + Power keys together till the screen turns on, then let them go to boot into recovery. Once you are in recovery mode, use volume keys to move the selection up and down and camera key to select the option.
Go to Wipe data/Factory Reset and select it. Select Yes on next screen.
Then, select reboot system now to reboot the camera, which will now boot properly.
If you run into any roadblocks while flashing the firmware, let us know and we’ll help you out.
Your Galaxy Camera has now been restored to stock firmware, and any changes you might have made such as rooting have now been reset.
Gingerbread — in its semi-official form — has already leaked out for the Galaxy S, running on Android 2.3.2 (not Android 2.3.3, which is the latest version out there). While some Galaxy S variants are yet to get Android 2.2, aka Froyo, it’s strange that Samsung has already got an Android 2.3 ROM ready (in beta). Though, we totally love it that we have a new ROM to play with and boast of that Android 2.3 goodness.
If you want to install Android 2.3.2 on your Galaxy S, here is what you’ll need to do.
Disclaimer: The procedures discussed here are considered risky and we will not be liable for any damage happens to you or your phone, including bricking. So, know that you’re on your own.
Follow these step-by-step directions to install Android 2.3 Gingerbread on your Galaxy S:
Download the leaked Android 2.3.2 ROM from here — named chúng tôi Size: 241 MB approx.
Extract the chúng tôi file to any folder of your choice. You’ll get 3 files:
Download the file: chúng tôi from here. Extract it to get these files:
s1_odin_20100512.pit (no need to use this file in this tutorial) and
Save your data now. To save the whole ROM you’re currently using, install ROM Manager for free from the android market. Open it, Install the clockwork recovery. And then, select Backup ROM, for full backup of all settings and data and apps.
Once finished backing up. Switch Off your Galaxy S. make sure it’s disconnected from PC and connect it only when told.
Now, put it in Download Mode. For that, press these keys together – Volume Down + Power Button + Home Button.
In the PIT box, select the 8.3 pit from the step 3.3. Full name of 8.3 PIT: s1_odin_20100803.pit.
In the PDA box, select this file (from step 2.3) — CODE_I9000XWJV1_CL31216_REV03_user_mid_noship.tar.md5
In the Phone box, select this file (from step 2.2) — MODEM_I9000XXJVE.tar.md5
In the CSC box, select this file (from step 2.1) — GT-I9000-MULTI-CSC-OXXJV1.tar.md5
Make sure all these boxes are ticked (do not keep them unticked) — Re-Partition, Auto Reboot, F. Reset Time.
Now connect your phone (which is in Download Mode since step 6) to computer.
Upon connecting, Odin will show “Added” under the message box.
Now, hit the START button to let the process begin.
When process at Odin finishes your phone will automatically reboot. You can unplug the cable now. That is, disconnect your phone from PC now, when reboot starts.
When your phone has restarted, you are on the Android 2.3 Gingerbread edition of Android. Congrats!
Check out the video below of our Galaxy S running Android 2.3.2. Surprisingly and very sadly, there is no improvement in benchmark score of Linpack — which is still at 14 MFLOPS, same as what we has with Android 2.2.
Update: Special Thanks to Lorbas — He’s the one who leaked the news for us all. If you’re looking for a Android News blog in Polish language, his website — chúng tôi — is the best place for you.
Update 2: We’re about to Root our phone with Android 2.3.2 ROM. So, check with us if you want to know the procedures along with the video. And guess what, Insanity already has a beta ROM running Android 2.3.2 Gingerbread and it’s pre-rooted too. We’ll also give that one touch, so expect some really serious — and fun — stuff to hit this page soon. Real soon.
A recovery is a separate bootable partition on your Android device that you can use to install system updates and repair (factory reset) your device. A lot more can be done using a custom recovery, but the stock recovery that comes pre-installed on your Android device is limited to these features only. And FYI, these features are integrated into the Android OS as well — when you chose to factory reset your device from device settings or install an OTA update, your device reboots and boots into the stock recovery to finish the job.
The stock recovery that comes pre-installed on your device doesn’t support touchscreen mechanism. You’ll have to use the Power and Volume buttons available on your device to select and navigate between options in the recovery.
There are multiple methods to boot your Galaxy Star in recovery mode. The most handy (and hardware coded) method is about pressing a combination of keys for a few seconds on your Galaxy Star. Others are software based, let’s have a look them below:
1) Boot into Galaxy Star Recovery Mode Using
This method is a fail-proof method that’ll always work for you, unless you’ve broken one of hardware keys. In such a case you’d be left with only the other two methods discussed below.
└ This is completely optional. You can choose to keep the device switched On if you wish to
Press and hold ‘Volume Up + Home + Power’ buttons together and release them as soon as you see the Galaxy Star logo on your phone’s screen.
Your phone will boot into recovery mode. Use Volume buttons to navigate Up and Down between options and use Power button to select an option in recovery.
2) Boot into Galaxy Star Recovery Mode Using
ADB stands for Android Debug Bridge, a tool used to send terminal commands to a Android device via a PC command line. ADB requires a bit of setup, but it gets the job done with much lesser effort than hardware buttons, so pretty useful in cases when you’ve to boot in recovery mode frequently. Also, if (for some reason) your hardware buttons aren’t working than this is a very good alternative to boot into recovery mode.
And make sure you’ve proper drivers installed for your device. You can download driver from this page →
Extract the file (ADB chúng tôi you downloaded from the link above to a separate folder on your computer
Prepare your phone
Enable developer options: Go to your phone’s Settings » select About phone » Scroll to the bottom and tap on “Build number” seven times to enable developer options
Enable USB Debugging: Open phone’s Settings » select Developer options » Tick the “USB debugging” checkbox (under Debugging section)
└ If the script shows any error than that means either your device is not connected or you don’t have proper driver for your device installed on your PC. For help with driver, check this page →
FYI, the ‘Boot into Recovery Mode.bat‘ script file that we used above to boot your device into recovery mode just uses one line of command:adb reboot recovery
If you already have ADB setup on your computer and you know how to use it, then you may just use the command given above to boot into recovery mode.
3) Boot into Galaxy Star Recovery Mode Using
Quick Boot (Reboot) APP
Yes! There’s an app for rebooting your phone into recovery mode, and it’s the most easier of the methods we discussed above. But it won’t work unless you’ve root access on your device, and since not everyone roos their device, we’ve put this as the last method here.
ROOT ACCESS REQUIRED
Open the app and grant Root Access
Select ‘Recovery‘ from the list of options and it’ll boot your device into recovery mode
If you follow me on any of the social networks on which we all live these days, then you probably know that I sold my iPhone 4S some time ago, and have been living with a Samsung Galaxy S3 ever since. There were brief flirtations with an HTC One X and Galaxy Note along the way, but that Galaxy S3 has been my daily drivers since long before the iPhone 5 was announced.
As that semi-dramatic title may have tipped you off though, I’m on the verge of ditching that Android flagship handset in favor of a shiny new iPhone 5. At least, I will be once I manage to find somewhere that will sell me one! That’s a whole different story though, and I digress.
So, having proclaimed the Galaxy S3 to be the best smartphone I’d ever owned just a few short weeks ago, what’s changed, and why am I ready to give it up in favor of Apple’s latest and greatest?
Firstly, a word on that Samsung phone. Until recently, I was happy to call it the best phone I’d ever owned because, in all honesty, it was. It has a nice, large screen that looks gorgeous. Yes it’s possibly a little too colorful at times, but there are ways to reduce that. The build quality isn’t as bad as I expected either, though obviously not quite in the same league as the post-iPhone 4 releases from Apple. I fell in love with Android too, with Google’s OS having come a long, long way since I used it last. All in, the package was just what I wanted and, in truth, I was perhaps ready for a change.
Months later though, I’ve come to a stark realization: I need to get another iPhone!
As much as I have enjoyed using this Galaxy S3, I still find myself having to think when I use it. That may sound odd, but with the iPhone I never had to consider how to accomplish anything. It was just there, a sort of muscle memory. That’s not to say I couldn’t work out how to use Android, or that it’s just inherently more difficult to use, because I don’t believe either to be true. It simply comes down to what you’re used to, and I’ve lived inside iOS for so long that I’m very, very used to it.
There are things I’ll miss about Android, too. I’ll miss being able to throw files and content into virtually any app thanks to its awesome ability to make everything feel interconnected. Apple still hasn’t quite managed that with iOS, and apps do tend to feel disconnected. It’s something you have to accept, and I have. It’s a trade-off, like so many things in life. It doesn’t make Android worse, or iOS better. They’re… different. It’s not a religious decision, and I don’t feel like I’m a bad person for switching, either!
I’ve not found Android to be lacking any of the apps I lived with on iOS, either, which was a surprise. Still, I find myself wanting to give Marco Arment’s new app a try which, obviously, is iOS-only. It’s little things like that, but when added together, they’re just enough to make me miss my 4S.
So where are we now? Well, I’ve got this Galaxy S3 that I’ll be keeping no matter what. But I need an iPhone as my daily driver. Something that feels like it’s part of me, something I can use without looking at the screen and that I know inside out. All I need now is for the local Apple Store to let me buy one.
But that’s a different story completely.
