[TUTORIAL] UNROOT the Galaxy S II on ICS to COMPLETE stock

How to get your rooted Galaxy S II I9100 back to complete stock
This means that you will have:
Stock Bootloader
Stock ROM
Flash Counter Set To Zero
Stock Recovery
INTRODUCTION:​So, the vibration on my SGS2 is broken, but I also rooted my phone, because, well, Samsung TouchWiz sucks. So anyway, being pedantic old me, I wanted to develop a method to reset my phone ENTIRELY to stock so that I could send it off to get repaired. I have found this method.
My main problem derived from the fact that USB Jigs no longer work on ICS which is irritating because I only just got it. I made this guide so there is finally something on the Internet where all the information is in one place.
NB: I AM NOT RESPONSIBLE FOR YOU DOING ANYTHING TO YOUR GALAXY S II AND THAT INCLUDES BRICKING THE DEVICE. YOU ARE DOING THIS WITH FULL-KNOWLEDGE OF ANY DAMAGE THAT COULD POSSIBLY BE DONE TO YOUR PHONE.
NB: ROMs like I9100XWLPM and I9100XXLQ5 are vulnerable to the eMMC bug and that willl brick your phone if you do a wipe/factory reset with CMW (probably stock too) Thanks cpl.Bower
Here's your shopping list:
A Windows PC or if you have a Mac, a Windows Virtual Machine (haven't used a vitual machine so not sure if it works, but give it a try and let me know!)
Odin which you can get here.
Chainfire's Triangle Away Application which you can get here or on the android market if you feel you want to donate to him.
ClockworkMod ROM Manager you can get here (I would highly doubt that as root user you don't have this)
Download your corresponding Stock Kernel from here.
So here is the method:
1) Open Chainfire's Triangle Away app and press "Reset flash counter" to reset the counter and remove the triangle. It does not matter if there is no triangle already.
2) Do a nandroid backup using Clockworkmod recovery if necessary (to get to it; turn off your phone, press the power button, volume up button, and home button at the same time and hold it down for a while). This is done so that you can restore your original OS like I would want to after getting my phone back from Samsung if you're restoring it for that sole purpose.
3) (Mandatory) Wipe Data/Factory Reset in recovery menu. IF YOU DON'T DO THIS, YOUR PHONE WILL BECOME STUCK ON THE "S" LOADING SCREEN. You also should wipe the cache partition and the internal SD card. The internal SD card in case you have any directories which may link you to rooting your phone, such as clockwork mod.
4) Restart into Download Mode and plug your phone into a windows computer.
5) Open Odin , click PDA, choose the STOCK kernel. Make sure that F. Reset Time, Auto Reboot and the PDA checkboxes are checked and NOTHING ELSE.
6) Click Start. The phone will restart now. It takes a while to load up as the applications need to install. Keep an eye on the phone, it'll ask you for your carrier. This does NOT mean the phone will be locked to a network.
7) Follow the instructions and set your phone up.
8) ???????
9) PROFIT
10) (Optional) You may want to check to see if your phone is set to stock to confirm. I cannot guarantee 100% that there will be no evidence of root on your phone, but hey, I still got warranty service after doing something similar to this on the old firmware.
To check to see if your flash counter is set to zero: hold down the power button, volume down button and home button until a "Warning!!" screen appears. Press volume up and make sure it says CUSTOM BINARY DOWNLOAD: NO and CURRENT BINARY: SAMSUNG OFFICIAL. You may also want to make sure that there is no warning triangle on the first screen when you start your phone
To check to see if your recovery is set to stock: hold down the power button, volume up button and the home button until your phone goes black after the first boot screen. To make sure it is stock, there should be no "CWM-based Recovery" at the top or anything indicating clockworkmod or any other custom recovery.
Any errors in the process (besides the one in the Q&A), I may not know what you have done. I have done this with my phone and it worked fine.
PLEASE REMEMBER TO RATE AND THANK ME
Q&A:
Q: I'm stuck on the "S" loading screen, what did I do wrong?
A: You didn't do a factory reset! To fix this, turn off your phone, go to recovery, wipe the data, reflash with the stock kernel and it'll be okay. If not, I have no idea what's wrong.
Q: How do I get to recovery?
A: Turn off your phone and hold down the power/sleep button, the volume up button and the home button at the same time until the first boot logo goes black, then you need to let go.
Q: DUDE, THIS TUTORIAL IS AWESOME, HOW CAN I EVER REPAY YOU OH MIGHTY MIKE?!
A: Rate this thread 5 stars and thank me.
Thanks for reading

If anyone can give feedback when they try this, I'd be thankful

Good job
If I were sending a phone in for warranty service/replacement, I'd go a step further with the factory reset & format cache, data, system, & internal sd card in CWM, then flash stock rom in Odin, then Triangle Away (If flashing stock ICS and assuming you have new bootloader) or flash old bootloader & use jig (if flashing stock GB).
Edit to add - Obviously also do a Nandroid before the above steps so you can get up & running when you get your phone back/new phone as you said

Ah yes, I remember wiping cache and dalvik cache too I will be sure to edit my post to add that! The internal SD card's contents may give away root, haha! I'll be sure to add that too! Thanks a lot, I'll credit you!

Nah, not wiping cache/Dalvik, actually formatting the cache partition in CWRecovery. And yeah, if you want to be absolutely sure; well as sure as possible in any event; you can't get a 100% guarantee of warranty service once you've gone down the custom firmware route, formatting the internal SD card should get rid of any potentially 'incriminating evidence'
No need to credit me, it's your guide, you deserve the credit

Ah right sorry, I misunderstood you haha! Well, I rooted my phone before and I honestly couldn't find a trace of root and got warranty service, but you never know!
I actually got warranty service while my HTC Wildfire was rooted, so I never see at as impossible!
I shall correct the mistakes, thank you once again

My method
Seeing as I bought the USB jig, I prefer to just do a full, thorough wipe as described above, then flash back to stock GB. A quick plug in of the old jig and it's clean. Also, the warnings about messing with bootloaders being a gateway to a fully bricked device put me off.
This thread is a great idea, though. I had to trawl over so many sites to find information about things like this. Good work.

Great guide, and just in time too. My SGS2 seems to have launched itself into its deathbed less than a week after the ICS update here in Australia. Battery life is barely holding overnight.
Thanks!

What are the benefits of flashing the ICS bootloader?

I put it there because it is the stock Bootloader for ICS... I had it at my disposal because I was going to flash an older bootloader so I could use USB jig and then flash back to the stock with the bootloader in the download section.
Honestly, unless you flashed some other bootloader, I wouldn't bother with it. It makes no difference really, I managed to get back to stock without doing that
Sent from my GT-I9100 using XDA

Its been along time since I last flashed through Odin (I normally flash rom's through cwm), but to get back to stock don't you simply just flash back an original rom which corresponds which your region ?
The rom should already have the correct bootloader and you should not have the yellow triangle as you have not flashed an insecure kernel ?

Because this is the only technique I find which ensures removed root and full stock on everything. Main reason for doing this instead of flashing via cwm is because this technique is extremely thorough. And what you flash in ODIN isn't a rom.

Nothing as flashing a stock ROM via Odin will flash the same Bootloader anyway.

I'm currently running a rooted GT-l900T on ICS 4.0.3 (Australia/Vodafone) and am trying to follow your guide, but there's one thing I'm unclear about.
You say to download a stock kernel for my phone. How do I tell which kernel to download? I'm currently running a rooted XWLP9, should I be flashing a stock version of this? Will it do any damage if it's the incorrect kernel?
I found the XWLP9 stock kernel in the link you provided, but it says that the region is Netherlands and the carrier is also different to mine. Does this matter?
I'm trying to claim warranty tomorrow for a hardware problem, and would appreciate an answer ASAP. Thanks for your time!

hey if i use custom rom like resurrection remix can i unroot my phone but still use the custom rom?

Hello, sorry for the wait, I've been doing important exams and have been occupied!
I just saw you're comment and I'm sorry you've had trouble. I have been doing much searching to help solve your problem and I *may* have found it.
I do warn you, i do not know the safety of this kernel and thus am not responsible for damage done this will be of your own consent if you did decide to proceed.
Here is a post I found while searching and it contains an international version of the XWLP9 firmware, maybe this is what you are looking for? I hope this helps!

Stock Recovery and Device Status

If I have a stock device (firmware, kernal and recovery) and I enter recovery, will that trip the customer rom or flash counter? I recently did so, and my device status is now saying "custom". Meanwhile I did not root, or flash anything.
-------------------------
Resolution:
Thanks for both of your help.
Here are the steps if anyone else is interested:
0) Back everything up, your phone might get bricked... so if your scared don't do this!
1) Root Device (CF Auto Root preferred)
2) Download, Install Triangle Away and run triangle away
3) Go to download mode (volume down + home button when restarting) and ensure you do not see custom for binary and system status
Click Here for Image
4) Go to http://www.sammobile.com/firmwares/ and download the latest firmware
5) Go to recovery mode (volume up + home button when restarting), factory reset, clear delvik cache, format partition.
6) Go back to download mode and flash the latest firmware
7) You now have warranty back, and completely stock

After doing so, allow the phone to boot up fully, and let it sit for about 2 minutes. Then restart and see if the custom status went away.

I've installed triangle away, reset the counter, download mode shows everything as official. I've installed a fresh copy of the latest rom via odin, removed SD card, removed battery... still no luck!!!!!

That is strange. Normally the following would always fix the custom logo:
- Odin to stock
- Allow device to reboot
- Let device sit for 2 minutes
- Reboot
(The 2 minutes is to allow SysScope to scan the system and subsequently mark the system as "Official" - you can check on its progress in Settings -> about device -> about phone -> Device status. Usually it only scans for the first :38 sec of a normal boot, but I've seen it take up to two minutes before. This timer doesn't include the time it takes your phone to do the "Android is Upgrading" thing.

So I managed to fix it... I downloaded and flashed the AMG1 July tom after wiping my partition entirely. Thx for the support.

The issues is related to the 64GB SD, don't ask me why, i've been on an intensive month long troubleshooting session to find out why but i never did. If you took out the SD and rebooted twice, official status would come back, although the new firmwares dont have that issue

Bricked S4?

So I have been trying to get multiple roms to work and it seems as only the TouchWiz roms worked for me (getting LTE) Jellybean wouldn't let me connect to any LTE but gave me data.
So I tried to do a few wipes, I deleted my backups (like an idiot) and now I'm stuck with just being able to get into TWRP.
I get into TWRP factory reset and wipe everything then do a internal wipe and install a rom the rom installs but when i go to reboot the rom it gets stuck at the Samsung Galaxy s4 screen and won't move.
What do I do?
I just want to have a jellybean rom...
I can get into TWRP

How long have you let it boot? The first boot can take a long time.

You need to read about TWRP before using it. You should not be wiping "everything" with it.

yeah i can i never used odin before.
if i do this will i be able to re-root? or will it update me to mf3?
EDIT: i just let it sit there and got my old recovery back. im on tw 4.2.2 goldeneye. let me check if i can reboot it without it getting stuck.
EDIT2: ok i just let it reboot and it now reboots fine..

I have read 3 of your posts, you really need to start reading before you go any further...if your phone boots on 4.2.2 GoldenEye, stop there until you find more information on what you are trying to do. If you don't you will for sure be using Odin soon, may want to read up on that also...
Good luck.
BTW, you do not need to make a different thread for every question, go back to one of the threads you started, and ask ALL of your questions there...

No Root after factory reset

Root just disappeared.
This is not a huge problem but when I go to TWRP to reinstall SuperSU, I can't get to the files so I can't install SuperSU.
I have now a MegaPixel ROM with EX kernel and I want to go back to stock. With no root, kernel and recovery... Just don't know how to.

I tried to reinstall SuperSU but now its stuck on boot animation. How can I fix this?

I don't think you can do a factory reset if you are on a custom Rom. Power down your phone by holding down the power button until the phone shuts down. Go into bootloader mode by pressing power and volume down buttons at the same time. Flash complete factory image from Google site using flash-all.bat command. If you don't know how to do that follow the XDA/Heisenberg guide only to the point where it shows you how to flash. Do not flash all the pieces individually like in the guide. Just use flash-all.bat command like Google suggests.

Use the link I posted above. Read it and follow the return to stock section. Like I mentioned earlier, that's a step by step guide to all things 6P. How to root, how to return to stock and everything in between. It has (or at least links you to) all the tools you need. It's a lot more thorough than I am, quite frankly. Just do your best to follow the return to stock section of the guide and if you run into any issues quote me again and let me know where you're stuck and I'll see if I can help. But you're asking for a step by step on how to recover and I've already provided you with a link with those exact steps. Good luck. Specifically steps 10 or 11 depending on if you want to keep your data intact.

What were the exact steps you took? Also, how long has it been boot looping? First boot on a factory image flash can take a while. I've waited like 10 full minutes before boot.

I did all the steps in part 10 with angler 7.1.2
It was bootlooping for 5 minute or so. I turned the phone off (While it was bootlooping) and now when I try to boot I get a "No Command" with a opened Android screen. What should I do now?
Maybe I can still flash TWRP and do stuff there?

The no command screen with an Android on its back is stock recovery. When you see that, hold volume up and while holding volume up, press the power button. That'll get you inside stock recovery. From there you can factory reset. This will likely wipe your internal storage. I'm not exactly sure on that, but assume it does. If that's not an issue, do it and try booting again, but wait longer this time. Leave in on the charger and wait 10 minutes or so. If it still won't boot, try again with 7.1.1 factory images. Also if you're using the flash all .bat file try manually flashing each partition using fastboot.
Edit: If you didn't already, don't lock the bootloader. You won't be able to use fastboot or flash TWRP (if that's what you want to do) with it locked.

Sounds like it. That's not good, it sounds​ like a real issue here. How did this end up happening in the first place? You factory reset from TWRP and all this happened? That should have not made you boot loop. You should have been fine and booted and had to sign in again, etc.
Did you lock the bootloader?

I did the factory reset from system.
I hope it's not a big issue cause I just paid 150$ to fix the screen. I just wanted to give it to my mom fresh (with no root, custom ROM etc...)

Yeah if you're not on stock, don't factory reset from the system. Use TWRP. Try to fastboot flash TWRP back on the phone and see if you can boot to that.

TWRP works! OK that's a good sign (I think so...)
I wiped EVERYTHING (Dalvik/ART cache, cache, system, Data and internal storage)
I will probably try to flash stock now.

Flash stock minus recovery, leave TWRP. See if you can get it to boot. Try 7.1.1 if possible this time, though.

I think I know why 7.1.2 didn't boot
I have a EX kernel updated to march security. I should download a stock with march security or lower.

Glad you got it sorted out!

[! HELP NEEDED !] encrypted J510FN only boots to recovery after flashing / wiping

!!! I apologize if this is the wrong thread to ask for help and kindly request that a moderator move it, because I don't know where it's supposed to go and my brain is in panic mode right now, thank you. !!!
So, here goes:
DEVICE INFO: SM-J510FN, TWRP, stock ROM, encrypted data partition
ISSUE: Phone does not boot. Powering it on makes it boot to recovery. Selecting "Reboot to system" from inside the recovery, also boots back to recovery. Cannot mount data partition as it is encrypted (but it doesn't at least ask for PIN or anything, just cannot select /data in mount).
HOW IT HAPPENED:
1. I encrypted the phone while it still wasn't rooted.
2. I flashed TWRP (via Odin) and SuperSU (via TWRP)
3. Phone booted to system normally, everything OK. Root access, all good.
4. Reboot to TWRP, flashed some blacked out Google Apps (Team Blackout .zip files). I got no error message, just "cannot mount data" at some points.
5. I selected "wipe cache and dalvik cache"
6. Reboot to system
Reboot to system doesn't work. It boots back into TWRP!
Now I don't know if the flashing of the .zip apps or if the wiping bricked the phone as I don't have that deep of an understanding of how it works. If you can enlighten me , I'd really appreciate it.
FEAR: That the phone is bricked forever and that I won't be able to format the data partition as I cannot even mount it and TWRP needs it mounted in order to wipe it (as far as I know). In short, phone ruined forever because of my stupidity.
HOPE: That someone will tell me a way to re-flash the stock firmware or any ROM so that I get the phone to boot up normally.
I really really need help ASAP because this phone does not even belong to me. My employer gave it to me as a gift, provided I use it for work. That's the reason it's encrypted, he wanted it encrypted in case it gets stolen. Now you're probably thinking "why would you root a company phone??" Well it's not a company phone, it is my main phone, my daily driver. It was given to me by my employer, who said I can do whatever I want with it, as long as it remains functional (at work I use it simply for phone calls, WhatsApp, Skype, mail etc)
I assume that I won't sleep much tonight, will try everything to get the phone to boot. But first I'm going to wait for any piece of advice!
Thank you in advance for any feedback...

Can you get into download mode?
If so, you should flash your stock firmware.

Yes if you boot into download mode you can flash stock rom and all will be good

Hello, thanks for the replies.
Yes, download mode works. I will download the stock firmware and flash it via Odin then, yes?
But what happens with the encryption then? Will it remain in place and I will just have to enter my pin to boot as usual?
Can you please explain to me why it does not boot now..? As far as I understand, the boot partition couldn't have been damaged. Aka, stock ROM still in place, only difference is it's rooted.

Not sure bout the encryption, if you lose it, you can set it up again.
Something went wrong when you tried to flash the blacked out google apps, I honestly don't have a clue.
Good luck

Haha I really don't care about the encryption at all! I'm just afraid it is going to interfere somehow but hopefully not.
I'm waiting for the stock firmware to get downloaded from sammobile. I know, I know, I should have done that first before anything else, but I was in such a hurry and I thought "OK, this is routine by now, nothing can go wrong", somehow completely forgetting about the encryption. Oops. In any case, I will post the results here later and will be VERY VERY prepared and organized in the future :'(

Ahh turns out I almost freaked out for nothing! All good! So, for documentation purposes:
1. I flashed stock firmware through Odin
2. Boot up started normally ("firmware update") - got asked for encryption pin!
3. Decryption took a long time, system booted normally - ALL DATA INTACT
4. No root and No recovery (not even stock recovery)
5. I flashed TWRP through Odin and SuperSU.zip
6. Phone booted normally, TWRP there, SuperSU app there.
The only change is that the bloatware I removed is back
I'm so glad it was nothing after all! I was honestly SO scared that I bricked it ^^;
Thanks and sorry!
