Unroot, Back to Stock Kernel? - AT&T Samsung Galaxy S II SGH-I777

I have read through posts...just need straight easy answers though, at times I am stupid.
I have a non stock kernel and rooted SG2. Where is the stock kernel(one that won't have the ! mark at bootup) and how do I Odin flash back to stock safetly?
If I go back to stock kernel, will it keep the count of kernels I had on the phone still? Or there a way to reset that easily?
Thank you!

Entropy512 was kind enough to put together a package just for this purpose:

Your best bet is the *NEW* - Kernel + non-rooted system package option.

If you buy a jig, and use it to put the phone into download mode, that will both clear the flash counter and remove the warning triangle. And all while remaining on your custom rom.
If you want to return the phone, then flash back to stock with the package mentioned above, and then do a wipe/factory reset in stock 3e recovery. That will also reset your flash counter and remove the warning triangle.
If you want to keep the phone and run custom software but not show the warning on boot, that is quite possible.

Getting back to stock w/o triangle

Hi all,
the screen of my beloved Galaxy S II has gone dead, everything else still seems to be working. I was running MIUI 3.x at this point. Now I am scrambling to get back to stock and to make sure there is no triangle showing up - which is extra hard because there is no screen I can verify it - and send the phone in for warranty.
So far I have done the following:
- Flashed to stock firmware XWKF3. I have a screenshot of the phone were it was running this so I think this is the best choice
I used the firmware from here: http://forum.xda-developers.com/showthread.php?t=1075278
Question 1: Does this also replace the kernel? At least the package includes a kernel which is the exact same size as the XWKF3 kernel separately linked on the page, so I assume everything is stock now. The phone booted up afterwards (I could hear some sound) -> good
Question 2: How can I get rid of the (likely still present) triangle? Will a jig do? Is there a way to verify it has been reset without a working screen, by reading some memory etc.? Do I need to flash an old bootloader to be able to reset it?
Anything else I should consider resetting?
Thanks for any help,

1. Yes, it will change your kernel to xwkf3
2. a.Jig should reset it, or if you can use triangle away app before downgrading to GB (i think this may be too late already), it will also reset it.
b. i don't think you can verify without a working screen
c. You might need to flash an old bootloader, if the one packaged with the stock firmware is new enough to allow jig reset method

[Q] 2.3.6 cant update to 4.0.4 because of flash counter?

I'm currently rooted on stock 2.3.6. I'm trying to sell the phone today and the guy wants me to update to ICS. I just have one problem... Whenever I flash back to stock everything, Kies keeps giving me the error that I'm not eligible. I assume it's because I tripped the flash counter going back to stock. How can I avoid this? Can I use Kies with a custom recovery installed to flash the flash counter wipe, and then it'll just remove the recovery?
Edit - Trying with a custom recovery and it said I was eligible.
I am no expert on here but lurk these forums, but I think I'll throw my 2 cents in here. I received a warranty replacement from ATT in the mail after the manager of the ATT repair center told his lackey to allow my warranty exchange. You see, I had mine rooted (on 2.3.6) and loaded with a custom rom (ICS 4.0.4) and the lackey could see the counter incremented and all. He gave me the script of not being able to warranty it due to the rooting but the manager could see that I knew what I was doing and that the issue (no sim error) was a hardware issue so he said he'd take the hit if it came back due to the flash counter. He had the lackey try to reflash it with official rom with their samsung tools just incase the sim issue could be fixed with a flash, but no cigar. All that did was leave me with an official ICS rom that was unrooted with a counter showing 1. A couple days later the replacement came in and I transferred all my info to the new phone.
Now just to be on the safe side, even though the manager of the corporate repair center ok'd it, I decided to return the defective Gnote back to stock unrooted condition with it's counter reset.
What I did was,
Flash the GB stock unrooted rom 2.3.6 using odin.
Then flashed CWM using odin.
Copied the ATT stock recovery zip and the flash counter reset zip to the internal memory. Reason being is that you will flash the counter reset with the custom CWM and then flash the stock recovery after to replace the CWM with the stock ATT recovery.
Afterwards I checked in download mode and the flash count was :no which means I'm in the clear and the underneath it said Samsung Official.
I haven't used kies, but I do know that using odin was painless. I'd suggest browse these forums for a while until you feel comfortable enough and then take care of the problem without Kies. Could be done in less than an hour after hitting a few links in the stickies of these forums.

Its got nothing to do with the flash counter. Unless your phone is completely stock, Kies rejects it.

It actually was the flash counter. I wiped the counter and then tried, rooted and with a custom recovery, and it worked. Stock with a 1 on the flash counter and nothing.

[Q] HELP!!!! Samsung S2 stuck at yellow triangle

Hello,
I tried to upgrade my S2 for Android 4.3 and i did the XWKDD Kernel. I flashed it sucessfully then i went to super click thingy and then rooted it. It was sucessful. After that, it shows the yellow triangle and tried restarting but the same thing. Eventhough after i flashed the kernel and it restarted then it goes to yellow triangle then i rooted it sucessfully. Same story all over again. Help as i need to use my phone!
btw its i9100. SSN- i9100GSMH
Boot into recovery, factory reset/wipe. No recovery ? Back to stock via Odin & start again (re-root your phone & restore backup, or re-flash custom rom/kernel & start again). How ? Get stock rom from Samfirmware, follow flashing instructions in thread stickied near the top of Q&A.

for the stock rom, i am confused as i cant remember which android version is it but it was 4.X.X for sure!
i tried to factory reset and wipe but nope. tried to start over again. same thing. how? how do i put android 4.3??
Forget Android 4.3. Your only focus right now should be getting the phone working normally again.
Go to Samfirmware, download a stock rom for your carrier/country (it doesn't matter which, just not 4.0.4), flash it with Odin. I'm not going to post this again :-/

i did download the stock rom and everything is working well thanks to you allthough my contacts are wiped out. i did back up on my computer except i lost the contacts....
so for now, how can i put 4.3 or some custom rom? i am bored staying stock for like 3 years and never rooted it. I mean i had this phone for too long.. and never had a chance to have a new one like S4 etc..
Glad you got it working.
Always, always, always follow the flashing instructions for the rom in question. They're always on the first page of the thread devoted to the rom in Android Development or Original Android Development & they're always very clear/simple.
So head on over to those sections & do some reading/research before you do anything else.
Edit - And the first thing you do after you root your phone (and before you install any custom rom) ? Backup. Everything. Contacts/calendar/etc synced to Google, backup call/SMS logs with TiBu, do a nandroid backup in CWRecovery, and backup your EFS with kTool/similar (keep one copy of this backup on your PC, and another on the external SD card in your phone if you have one). Backup, backup, backup, backup. At least once a week or before you make any major changes to your phone (like flashing a new version of a rom or kernel). That way you don't lose your contacts/other stuff if things go pear shaped.
thanks to u as i followed the instructions via researching haha
Now i have official CM10.2 which i have done with cmw yet i might try for a custom CM10.2 like something to do with hybrid or stuff like that...
But, when i restart or switch on. it still have the yellow triangle then for a few seconds later n it booted to CM which is fine.
Why is the yellow triangle there? have i not done it properly?
Thanks
If it were me, I wouldn't worry about the triangle. You only need to worry about it if you need to make a warranty claim. If you want to get rid of it, read the Triangle Away thread on here.

[Q] Quick question about unrooting please

Hi, I'm a middle aged person struggling to get to grips with unrooting.
Situation is this
I want to return my phone to an unrooted state for a warranty repair.
I have only rooted the phone, but not flashed any ROMs
Do I just need to re-Flash the correct official firmware, for Vodafone UK, using Odin and then it will be unrooted?
And then use a jig to reset the counter?
Are there any other steps I need to take.
Thanks for your help
Yes, if you flash a stock rom that will unroot the phone, you could also flash just a stock kernel if you can get hold of one - search the usual haunts (Samfirmware/etc).
A jig will probably work only if you've been running Gingerbread stock roms, if you've been running ICS or JB stock roms, use Triangle Away to reset the flash counter before you unroot/flash another stock rom or kernel, then flash away.

Hi MistahBungle, huge thank you for this, just the pointers I needed. Very good of you to help some random bod on the Internet. I found the firmware I need and have installed Triangle away.
I'm all set really, going to do a bit more refreshing of my memory before I go for it. One thing am slightly curious about but will Google it, is if you reset the counter with Triangle away, and then I re-flashed the kernel with a stock, won't neck count as another flash, or is the flash counter only active if the phone is being rooted? No need to answer as long as it works
Thanks again for your help, much appreciated
No probs No, flashing stock won't trip the counter again. Good luck/post here again if you have any dramas.

[Q] Return phone to stock for sale

Hi Folks,
I am selling my GS3 to Mazuma mobile for £90 & need to return the phone to stock samsung rom from the custom rom I'm using at the moment (Fusion 2.0.6)
1 Use philz recovery to do full phone wipe & also the install new rom wipe.
2 Use Odin to flash the last UK BTU stock rom MK6.
3 Possibly use TriangleAway to get rid of the red exclamation mark when phone first boots.
4 Possibly flash stock rom again to be sure.
Are those steps ok or is there anything else I will need to do?
Would really appreciate quick reply as I will be wiping & flashing stock tomorrow before posting to Mazuma the same day.
Cheers.

Download official stock rom for your region, wipe data/cache from recovery, put phone in Download mode, close Kies from Task Manager, start Odin, connect phone to PC and flash stock rom. After the flashing process is done enter recovery and make wipe data/cache and then reboot. Use triangle away to clear the binary count + the exclamation mark. If it needs root permission flash a custom kernel to gain root and then re-run triangle away. After clearing the binary count and exclamation sign you can re-flash the stock rom. Make another wipe data/cache after flashing it and you should be good to go
Goodluck mate !!!:thumbup::thumbup:
Sent from my GT-I9300
Cheers for the reply AlexVat
Was kinda hoping it wasn't going to be so complicated lol, I assume when I flash stock rom with Odin that will wipe Philz recovery & just have the stock one?
Could it be possible to run triangle away first then then just flash stock rom?
All replies appreciated
Well triangle away didn't work when I ran that first & it didn't even reboot into it's custom recovery, also thought I borked my Samsung 32gb SD card, used my S3 to erase it after copying everything off it I needed but it then wouldn't mount again. Tried it in PC & kept getting write protected error when trying to format it.
As last resort I fired it into my Sony Z2 & it said it was corrupted, tapped the message & it then fixed what ever was wrong with it & formatted it. Will just flash stock rom tomorrow morning & fire it to them, from what I see online they don't really care if it was rooted.
All done, custom binary says no & stock BTU MK6 rom installed, will get posted tomorrow & will have £90 in my bank by Sat
Also getting replacement Z2 due to gaps, over heating & camera being off centre, will be checking it fully & using built in diagnostics to make sure screen has no dead pixels etc.
Mods can close this thread if they wish, many thanks to AlexVat for the help
