IMPORTANT: This guide is for the i9300 variant of the S3. Those with other variants - Please use this guide ONLY if you know for sure it will work for you.
For those with the Verizion S3, it was reported that you can use this guide: http://forum.xda-developers.com/showthread.php?t=1762709
The problem is that many of you may have unlocked your bootloaders, and this guide DOES NOT apply if you need to re-lock.
Right - I hope this is the correct section. I only just completely restored my S3 to factory state and I had to use so many articles over the web, half of them not even bringing me back to the original state. If you follow this, you will bring it back to a condition that will in effect recover your warranty and you'll be able to send it off. I'm also a new member(just signed up today) and I actually signed up because I wanted to post this haha.
==========================================
What this will leave you with in the end
==========================================
1. Official Firmware
2. Official Recovery
3. Binary Counter set to 0
4. Device status to "Normal"
5. Factory Settings as if you just took it out of the box.
=========================================
This will help you if
=========================================
You've soft bricked your phone but can still access recovery and want to reset
You've installed a custom recovery and want stock
You want to unroot and remove the modifications made (including a custom recovery such as CWM)
You want to reset the binary counter
THIS IS A DANGEROUS OPERATION AND COULD POTENTIALLY BRICK YOUR DEVICE. PROCEED AT YOUR OWN RISK. I AM NOT RESPONSIBLE FOR ANYTHING ON THIS THREAD AND FOR ANYTHING THAT WILL HAPPEN TO YOUR DEVICE AS A RESULT OF FOLLOWING MY GUIDE. BY FOLLOWING IT YOU ACCEPT THIS.
Process Overview
1. Reset Binary Counter
2. Flash Stock Recovery
3. Device Wipe
4. Flash Stock ROM
5. Done!
Instructions
1. Reset Binary Counter
Right so the S3 has a feature known as the binary counter - this counter is incremented everytime you flash any unnoficial software. This includes any custom ROMs, Kernels, and Recoveries. Chances are, during your rooting process you installed a custom recovery such as ClockWork Mod. This means your counter is not at 0, and your system status will be that you're running unnoficial software - WE NEED TO GET RID OF THIS.
=====================
Steps:
=====================
1.1 Turn off your phone.
1.2 Press the Home, Volume Down and Power buttons together.
1.3 Press Volume Up to continue when prompted
1.4 You will now see the binary counter will have an integer other than 0. Note this value down.
1.5 Download: TriangleAway. You can do this by going to this thread: http://forum.xda-developers.com/showthread.php?t=1494114
1.6 Copy it to your phone's memory or SD card.
1.7 Use any file browsing software to install the apk you downloaded.
1.8 Open the application and follow the notifications shown.
1.9 Find "Reset Flash Counter". The details shown should match your binary counter that you noted down earlier.
1.10 It may also say "this information cannot be retrieved" or something of the sort - in that case you can go ahead (I had to do this) and press reset flash counter. It will now boot into it's own mode. Follow the instructions to reset.

To remedy this, you can either:
1) After pressing the volume key in Triangle away, interrupt the boot up by pulling the battery. Check in download mode. If 0, move on to next step - otherwise, repeat
2) Flash an ICS Bootloader via ODIN first. ICS bootloaders are reset permanently once reset via Triangle away
3) Flash a stock recovery and kernel via ODIN so the flash counter doesn't increase once reset via Triangle away
4) Flip the entire process around. Flash a stock ROM first, root with CF Auto root. Run triangle way then use the superuser app itself to unroot.
Hope this helps.

1.11 Your counter is now reset! You can check it by repeating the first 4 steps.
2. Flash Stock Recovery
(Skip this step if you have stock recovery already)
We need to do a full wipe of the system. To do this we need to go to our recovery but OH **** we've got a custom recovery. If we go into this recovery then we'll set the binary counter back to 1 again and it'll defeat the purpose of the first step. If we, however, use a stock recovery then the counter will still stay at 0.
=====================
Steps:
=====================
Credits: http://galaxys3root.com/galaxy-s3-t...l-stock-recovery-and-update-ota-on-galaxy-s3/
2.1 We need to go back to ODIN mode (where you observed your binary counter).
2.2 Turn off your phone.
2.3 Press the Home, Volume Down and Power buttons together.
2.4 Press Volume Up to continue when prompted
2.5 Download ODIN: http://stockroms.net/file/Tools/ODIN/Odin3v185.zip (this is the version I used)
2.6 Download your StockRecovery:
Stock Recovery for International Galaxy S3 GT-i9300 (This is the one I used because I'm from the UK)
Download Stock Recovery for Galaxy S3 SGH-I717/I717M (AT&T,Canadian)
Download Stock Recovery for Galaxy S3 SCH-I535 (Verizon)
Download Stock Recovery for Galaxy S3 SGH-T999 (T-Mobile)
Download Stock Recovery for Galaxy S3 SPH-L710 (Sprint)
2.7 Run ODIN. Do not touch any of the options. Only Auto Reboot should be checked.
2.8 Plug in your phone. The first COM rectangle should be yellow (like: http://gyazo.com/ad7dcd2af17a7ff6745ded7ea91eefaf ) and ODIN should recognize the phone. If this is not the case and it's not recognizing it then you need to get drivers for your phone.
2.9 Click "PDA" and select the stock recovery file you just downloaded.
2.10 Click Start.
2.11 When complete the top left will be green.
2.12 Now you have a stock recovery!!
2.13 Unplug your phone
3. Device Wipe
3.1 Go into stock recovery by holding down Home, Volume up and Power buttons together.
3.2 When you see the samsung logo, let go and you'll see it go into custom recovery.
3.3 Scroll to device wipe using the volume keys.
3.4 Press the home key to select the option, and then select yes. Once the device is wiped it will let you know.
4. Flash Official ROM
4.1 Download your official ROM here: http://samsung-updates.com/device/?id=GT-I9300
4.2 Choose the correct ROM corresponding to your country, I chose BTU since my phone was unlocked and I'm from the UK.
Please note: it is IMPORTANT that you download the correct ROM. Dial *#1234# to find your CSC (country code) and CP number which you can match up to the ROM.
4.3 It's around 800MB so it will take a while to download.
4.4 Go to ODIN mode again by
4.5 Press the Home, Volume Down and Power buttons together.
4.6 Press Volume Up to continue when prompted.
4.7 Run ODIN on your computer and connect your phone.
4.8 When it recognizes it, check "Auto Reboot" and "F.Reset Time".
4.9 Everything else should be left unchecked.
4.10 On your computer, unzip the ROM file you downloaded. It should give you something with the extension of .tar.md5
4.11 Press "PDA" on ODIN and select this file.
4.12 Everything should be as shown here: http://gyazo.com/fea7a1c8b7a7b5bb287fb0a0c70056dc
4.13 Click Start and wait for it to do it's thing. It'll take quite a few minutes.
4.14 When it's finished, you're DONE!!!!
IMPORTANT: If when rebooting, it hangs at the samsung logo for a while then perform STEP 3 (Wipe Device) and then reboot it. Should work. If not then post here and someone may help you OR you can attempt reflashing your stock ROM again.
And that's it folks I'm not very experienced with android so I won't be able to answer questions if you have any problems, this is just the steps I devised and it worked.

[Tut] Unroot the Galaxy SIII (for stock updates/warranty) 14 June 2012.

Thanks for unlocking - hope you guys can make use of this. Feel free to ask any questions.
Can I add that between steps 10 and 11, if you have a custom kernel or recovery, and a JellyBean bootloader - when the phone boots, the flash counter goes back up to to 1.
To remedy this, you can either:
1) After pressing the volume key in Triangle away, interrupt the boot up by pulling the battery. Check in download mode. If 0, move on to next step - otherwise, repeat

Thanks a lot mate, will add it to the original post!
Can you confirm this procedure?
1)flash stock firmware with odin (for example MC2 4.1.2)
2) root + recovery
3)downgrade to XXALE8 bootloader
4) triangle away
5)another flash of stock firmware to uninstall recovery e root
It is the correct procedure?
I read about some issue in the 5) point (fail of odin in sboot.bin).....can I flash another time the stock firmware over the old bootloader?
Stuck
Thanks for the guide!
I'm having issues with step
2.10 Click Start.

Probably to stay on the safe side bring it back to the stock bootloader first?
OP if the original post is to be of use then it needs to be locked .
Alternative is it will just turn into a question thread that has nothing to with the original guide .
jje
i figured out a way to restore full stock
i figured it by my self, thinking, what if i boot into fastboot, will it increase binary counter? it does not! so...
1. Reset binary counter using Triangle Away.
2. Hard restart your phone ( "-" and power for 8 seconds) and instantly when it happens hold key combination for download mode ( "-" and home and power).
3. Flash stock firmware (after that counter = 0 will not be increased).
4. Factory default (required to clear "modified" status in system settings).
5. Done! Full and clean stock
Download mode *

I'm currently using the Omega v10 ROM but I would like to go back to completely stock. I also flashed a new modem bc the wifi didn't work when I installed the custom ROM. How should I start? Should I use Triangle away first, reset the counter and after that flash the stock firmware? I'm using an UK unbranded GT-I9505 and downloading this stock firmware file for it:
United Kingdom BTU (July 2013)
PDA: I9505XXUBMGA
CSC: I9505OXXBMG3
Version 4.2.2
When should I flash the modem and where can I find it? Also, how can I go to download mode directly after reseting the counter?
Thanks :}
I usually have problems with the wifi after flashing myself, but heres how I do it:
1. Flash either stock or pre-rooted rom from the thread in xda. Doesn't matter if wifi isn't working here.
(1.5. Root the stock rom with cf-auto-root if it's not already).
2. Install triangle away, and use it.
3. After triangle away finishes up and gives you the option to go to download mode, do that.
4. Flash stock rom (or whatever rom you want), with auto reboot off.
5. Power down phone after its finished. Then power back up, and go into the recovery (it should be the stock recovery).
6. Do "Wipe data partition" then "Wipe cache partition" (phone will reboot after doing this one). You want to go directly to download mode again after the phone reboots.
7. Flash the modem, as "Phone" in odin, with auto reboot off.
8. Restart phone again into download mode, flash modem again with auto reboot off. Then start up phone as normally when flashing is done. Hopefully the wifi works after that.
It is long, and sometimes doesn't work but its my best method so far. Using triangle away seems to help it.
EDIT: Triangle away gives you the option to go straight to download mode after it finishes. Also there is a thread here on xda which has all the modems. If you are restoring to MGA, the Omega thread has the modem in the installation instructions I think.
Hi,
Modems are HERE
Hello all!
First off I would just like to say thank you, thank you, thank you. I have been a long time lurker on these forums (since the evo) and have gotten a lot of useful information from here. Now to my issue. I have had no phone for two weeks now, and have been doing search after search. I upgraded my phone to 4.3 (it was mk2) and rooted it via motochopper. So my dumbass tried to flash a custom rom with kn0x0ut and it failed. The phone rebooted and now will boot up to the samsung custom screen. You can hear the att boot up sound but no image. I can get into odin mode and stock recovery. When I am in odin it says:
ODIN MODE
PRODUCT NAME: SGH-I337
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Official
KNOX KERNEL LOCK: 0x0
KNOX WARRANTY VOID: 0x1
CSB-CONFIG-LSB: 0x30
WRITE PROTECTION: Enable
eMC BURST MODE enabled
I have tried sideloading the stock MJ9 and MK2 files to no avail. I really hope somebody can help me, I don't know how much longer i can go without a phone. Thanks guys and Merry Christmas!!!
yea sounds like bricked you cant flash roms on 4.3 yet take it to best buy that has a samsung center and just tell them samsung sent you here because my phone all of a sudden was acting up and they will flash it back to factory for you thats what i had to do
gtj0 said:
OK, If you're stuck with an incomplete flash, here are some steps you can try to get to MJ9...
These instructions assume you started with MJ6.
First, make sure you can boot into recovery. If not, download and apply the MJ6 recovery.
recovery-mj6.tar.md5
It should apply without error. If not, report the failure.
Download and extract the following files...
mf3-emergency-part-1.tar.md5.7z
mf3-emergency-part-2.tar.md5.7z
If you don't already have it, download the mf3-mj9 update file...
update-mf3-mj9.zip
Start Odin, connect your phone and boot into Download mode.
Flash mf3-emergency-part-1.tar.md5 which contains modem.bin, NON-HLOS.bin and system.img.ext4.
The flash of system.img.ext4 WILL FAIL at the end. That's OK.
Reboot the phone back into Download mode and restart Odin.
Flash mf3-emergency-part-2.tar.md5 which contains cache.img.ext4.
The flash WILL FAIL at the end. That's OK.
The phone should now reboot to recovery by itself and apply a small update. If it fails, stop and report.
The phone should now reboot to a black screen with the pulsing notification LED.
Reboot into recovery mode and flash update-mf3-mj9.zip. I recommend sideloading instead of flashing from sdcard because the sdcard method reboots the phone whether the update was successful or not and you lose the error messages.
Reboot the phone and let it initialize.
You should now have MJ9.

I was on MK2 using the 3.7 beta of SS when I couldn't get it to boot anymore. Tried the modified method outlined above, everything worked except after step 7, it never rebooted to recovery on it's own and installed a small update. Decided to try Kies, says it can do emergency firmware recovery but it hasn't worked yet. Any help would be appreciated as I'm not sure I can get the handset replaced since I got it at Walmart.
It may not automatically reboot into recovery, just make it.
if you do not already know this (i am not saying you don't)
holding the power button for 10? seconds will reboot phone or using the file in post below

open terminal on computer and
adb sideload "update.zip"

I tried the above mentioned but after I flash the second file and reboot, it goes into kies , no recovery mode. Odin is still available. Also thanks for all the quick responses fellas yall are the best.
***UPDATE*** flashed the recovery but the sideload failed. Tried to turn it on and the Samsung lolgo came on, then went black. After a a few minutes the phone pops up on the computer and I can access the internal phone memory and the sd card.
I am really not sure, I believe that it will work if you do this process again.
No Idea if this makes any difference but, pay close attention to the process at least until the sideloading of the update.
Do not let the device attempt to boot with this firmware mismatch as this may cause issues. (This is the only conclusion I can come to as this process does work)
If the device automatically reboots then press and hold volume up to enter recovery or volume down to enter download mode.
If manual reboot or powering on then press and hold volume up or down respectively then press power until the device starts and release power button to avoid a reset.
SOLVED!!!

You are a new member here and I don't know your level of experience with phone modifications, so I'm going to make some assumptions.
Don't know if you can, but if you can boot into stock recovery, you should try performing a wipe data/factory reset.
What we would probably do in your situation is to use desktop Odin to flash the most recent stock firmware that is available, which is I337UCUFNB1 KitKat 4.4. After doing that, you could either try the over the air update process again, and it may work successfully, or you can upgrade to I337UCUFNJ4 KitKat 4.4 or to I337UCUFOC3 Lollipop 5.0.1 manually.
A good starting place is this thread. The instructions there are fairly clear, but you may need to do a little study and reading to get enough background information. There is a lot of information already in the forum here. You should be fairly confident that you understand what you are doing before you proceed.
Thank you for the response. I have tried the hard rest with no change. I have tried flashing back with Odin. Odin will connect with the phone but the connection drops at the first reset.
I have tried to restore with kies but kies does not recognize the phone.
I have also tried to flash with a new rom on the SD card. That has not worked either. I believe the problem is with the csc file but I have no idea how to fix it.

How are you using Odin? I don't understand what you mean by "the connection drops at the first reset."
The procedure is:
Open Odin on the desktop.
Put phone into download mode and connect to the computer via USB cable.
Odin will recognize the phone. Message area should say "Added."
Place the firmware .tar.md5 file in the PDA slot (AP slot on newer versions of Odin)
Make sure Auto Reboot and F. Reset Time are checked and all other items are not checked.
Press Start.
If the flash is not successful, copy and paste the results from the message area into a post.
By the way, you are flashing AT&T firmware, and CSC should not be an issue, regardless of the message you read on the phone.
I am using Odin just as you described but before the file transfer is complete the USB connection is dropped (disconnected). The progress bar on the phone only shows about 10% and never finished.
I am using i337 firmware and have been for 18 months. I have flashed several ROMs with no trouble
Sent from my Z812 using XDA Free mobile app
It's been a while since I've flashed anything; at least a year, though more likely two. Whatever I have now I'm guessing is a rom called stock(ish)v06, since that's what is listed in my bootloader. I guess the modem (baseband?) is NAE, and I'm still using a very old version of TWRP (2.6.3 according to my signature, haven't checked).
Obviously, the development that still exists for this device has moved well past me. But given how temperamental my device has been lately, I want to give flashing something newer a shot before buying a new device.
Trouble is, I'm not sure how to go about flashing roms and finding the right modem/firmware when everything I have is so out of date.
Suggestions?

I guess the modem (baseband?) is NAE, and I'm still using a very old version of TWRP (2.6.3 according to my signature, haven't checked).
Obviously, the development that still exists for this device has moved well past me. But given how temperamental my device has been lately, I want to give flashing something newer a shot before buying a new device.
Trouble is, I'm not sure how to go about flashing roms and finding the right modem/firmware when everything I have is so out of date.
Suggestions?

Download latest fully stock firmware so you will have latest bootloader and modem from http://www.sammobile.com
which is Lollipop, then flash latest TWRP. If you like stock, there is a stock deodex ROM, there is the awesome Wicked X (heavily modified Lollipop stock), or if stock is not your thing you can get CM12(Lollipop) or CM13 official(Marshmallow)

I want to make sure I understand what you're telling me to do, so a few clarifying questions:
1) I am meant to be updating TWRP first, then using it to flash stock firmware to update the bootloader and modem, and then flashing a rom of my choosing?
2) Why is that method preferable to using Odin to update the modem?
3) If I flash this newer official firmware, am I going to lose root?
4) In flashing the newer firmware, won't my bootloader lock, making it not possible to flash a new rom?

1) No, use Odin to flash full stock that you downloaded from sammobile.com, you cannot flash full stock from recovery.
2) Because some if not most newer ROMs require you to be on Lollipop bootloader.
3) Yes you will lose root, but this flashing of stock firmware is to update your bootloader and modem so you can flash the newest ROMs. The lack of root doesn't matter since you will be flashing latest TWRP via Odin and modified ROMs soon after.
4) if you have Sprint L720 the bootloader isn't locked. Check I'm 'about phone' to make sure you have an L720 and not another variant of S4
Make sure Samsung drivers are installed on your computer.
So your flashing steps go as follows:
1) Download everything you need first:
a) Full stock from http://www.sammobile.com to your computer
b) Latest TWRP tar file to your computer
c) The custom ROM of your choice (and correct gapps if AOSP or CM based) saved on external SD card on your phone since it will be flashed via recovery.
2) Turn phone off completely. I pull the battery then put it back in then boot directly to download mode: power + volume down. (Rebooting to download mode doesn't always allow a proper flashing)
3) Start Odin (uncheck reboot and reset time) and then plug phone into computer.
4) If COM lights up green in Odin click AP and select the file you downloaded from sammobile (it will be PDA instead of AP if you are using an older version of Odin) and click OK or start (I don't remember which it has)
5) If it flashes successfully pull the battery and then put it back in and turn the phone on normally. It will take a while to boot, like 15-20 minutes possibly. Flashing stock myself I have seen it say it was successful and it wasn't and the fix for me was to leave reset checked and let it do it's thing.
6) Once you have booted into your newly flashed stock OK3, do step 2 and 3 again, so you can flash TWRP.
7) When you go to flash TWRP in Odin uncheck reset time and DEFINITELY have reset unchecked (if Odin reboots your phone TWRP doesn't stick). Do step 4 again except this time select the TWRP tar file. Once it flashes successfully pull battery put it back in and boot directly to recovery (power + volume up) from there do a backup if you want, if not you can flash the custom ROM and gapps if necessary that you downloaded earlier.

Thanks for the very detailed response. This totally clears up my questions. I'll charge my phone this evening and give it a shot in the morning when my battery is at 100%. :good:
