[Q] Unrooting - T-Mobile Samsung Galaxy S 4

I had a warrenty on my galaxy s4 and I rooted my phone, installed a custom ROM, installed root apps, and installed a custom kernal. I Need help on how to get my phone COMPLETELY back to stock everything so i can take it to tmobile....and reset the bianary/flash counter. Im only 14 and i really like experimenting on my phone but its time to stop sorry ima noob xD Thanks so much!

If your bootloader is after MDL (4.2), you can't completely restore to original stock as the Knox counter is permanent once tripped. Knox started in 4.3.
Otherwise just do a factory data reset, flash stock firmware with Odin to get back to stock, and you should be good.

Do I need to downgrade to stock jelly bean every time I want to flash something new?

I recently rooted my S3 and am running frostys basic jelly bean Rom. I've installed CWM and checked my flash counter and its at 0 and I want to keep it that way. So do I need to go back to stock jelly bean through Odin then flash the new Rom that I want to try?

After the 4.1 update samsung updated their bootloader. I completely wiped my phone and it still is tripping the flash counter ever time you boot to recovery. Even after wiping everything. Even if you flashed stock ICS, after you flash your Recovery of choice through Odin you are going to trip the counter.
I am in the process of writing a guide to get back to Complete stock with a zero flash counter.
The point is, you are going to trip your counter. Dont panic, it is 100 percent resetable.

I downloaded Rom Manager off the play store and flashed the recovery through Rom Manager and I've gone into recovery countless times and my flash counter still says zero. I just got the phone Friday and it came pre-loaded with JB. You said you trip the counter every time you enter recovery? Weird!
Edit - I followed the guide from this thread http://forum.xda-developers.com/showthread.php?p=33115777 but I installed the ICS version first then flashed to frostys all while not tripping the counter.

I think that is the only wildcard. I flashed my recovery from Odin on my computer. Reset it via Triangle Away, booted back to recovery, and it tripped it. I remember reading that if you use Rom Manager then it doesnt. Im not sure why or why not but yes if you Odin recovery then you trip flash counter with each boot to recovery.
I have done much testing/goofing around. And no matter what scenario you are in, it is always able to flash back to stock 4.1.1 with a zero flash counter.

So then since I've gotten the wildcard does that mean I'm free to flash whatever rom I'd like without ever tripping the counter?

[Q] Restoring S3 to factory condition?

Hi everyone,
I have a Bell GS3 that I'm going to be selling to pay for a GS4 upgrade. I have it rooted and running Liquidsmooth, I'd like to restore it so it's like it came from factory. I have the I747MVLDLK4_I747MOYCDLK4_BMC file along with the Odin flashing program. I know there's something about tripping a flash counter, is there a way to check if it's been activated and if so reset it? I have an extended warranty on the phone so if the person does need a repair will not have to deal with certain problems.
I'd appreciate any help.
Your flash counter most likely has been tripped. I'm pretty sure the only way not to trip it is to use the root injected odin files. As soon as you install custom recovery and boot into the recovery the counter will be tripped though.
Here is how I have done the process.
Factory reset device.
Install triangle away to reset the counter
boot into download mode to flash stock firmware with odin.
If coming from a cm based Rom I find it best to restore/flash a touchwiz Rom first then factory reset, triangle away, Odin.
Hope that helps

Thanks for the reply. I may be misreading what you posted, are you saying that once it's been tripped there's no way to actually go back completely?
I'll do the steps like you suggested. Thank you.

If you use triangle away before you flash stock it will be the same as it was before you rooted = 0 counter. You can root with the root injected stock images and keep the counter intact. Once you install a custom recovery it will trip your counter.
It doesn't matter to someone who flashes roms if the counter is tripped until you need to sell or return for warranty. Triangle away before flashing stock will reset the counter and give you stock with a clean counter and ready to sell/return for service.

Thanks for the help guys, really appreciate it.

Knox bit tripped, stock questions

Tried reverting my T999L back to stock last week and used the root66 firmware (4.3 of course) and was able to get my phone back in working condition, unfortunately the warranty bit is now tripped and I can no longer flash things inside of Odin (haven't tried mobile, probably the same outcome).
With the JUMP program through Tmo changing now and the warranty bit tripped, what are my odds of being able to trade it in without any questions?
Also, how would I go about going back to stock with Odin no longer working?
***I currently have the stock setup through root66, with TWRP recovery installed if that gives anymore info to make things easier***
Just because Knox bit is tripped, should not make Odin stop working. What is the issue with Odin ?
So long the phone's working, hopefully Jump will accept it. Not sure just guessing.

I'll have to check back tomorrow and get back to you, it might have just been the recovery I was trying to flash. Ended up dd'n that.

My warranty bit has been tripped and I can still use ODIN no problem
I'm running the T999L Root66 4.3 ROM on my phone and am planning on trading it in on Friday (hopefully) and want to 100% factory reset it. I've already grabbed the 4.3 stock odin file from doc's thread and I read through the thread, but couldn't find this answer.
Once I run the odin file and reboot it, none of my data should be there from before right? Or do I need to then hit the factory reset from inside the ROM? Will I need to run triangle reset after running odin? Everything looks OK currently inside the app.
Thanks again for everything!

You will have to go to Stock Recovery after flashing 4.3 Stock. Hit Factory Reset there and you are good to go.

If I understand the packing of the files, that is included. Giving it a shot now

new phone from tmobile with 4.3 already installed need help downgrading

just got another galaxy s4 from tmobile and im trying to downgrade back to mdl instead of mk2 i already tried to odin but it keeps falling now im stuck at the keis upgrade screen
The only way you can downgrade is to flash a ROM in custom recovery.. Why would you want to downgrade?

well i was told that if i didnt i would have to deal with all the knox crap but as i stated right now im stuck at a screen that says firmware upgrade encountered an issue with a phone icon with a yellow triangle in the middle with a computer on the other end is there anyway to boot from this screen
Try to Odin 4.3.. There's no way to downgrade it without tripping the warranty counter. And fyi you can just flash a custom 4.3 ROM, no Knox

Here's the deal with ur new phone..
1.- as stated before u cant downgrade, Samsung or Google Made the 4.3 so U cant Downgrade even thru Odin. (well u can but you won't get Rid of Knox counter and U will need to "void" your warranty by flashing a different version of android)
2.- You can still Root your phone without triggering Ur Knox Counter which since u are already have since you're on 4.3 and u cant get rid of it.. Just use CT-Root, debloat the phone and install whatever Root apps u enjoy (this is my current state since I too Had to exchange my phone)
3.- If you do decide to root your phone, only way to trigger the Knox counter is by installing a Custom recovery and Flashing anything thru it.
at this point it all depends on what u want to do with your phone, stay on Pure NOT ROOTED stock or Rooted Stock with no recovery or just go all out and root install recovery and trigger your Knox counter "loosing" ur warranty

[Q] Flashing stock rom on non-rooted phone

Would flashing a stock rom on an unrooted phone trip knox? Thanks.
Don't think so. Could be wrong lol.
Just do a factory reset in recovery= brand new start
