I need to return my S3 as I've received my new one via insurance from ATT. The internal LCD is cracked and does not work - pitch black. So, I'm guessing it is best to flash it back to stock from KyanROM. Now I have a few questions:
Do I need to flash to stock for insurance purposes? I believe I found a youtube video that shows how to do a hard reset of data to wipe it clean (that way I know how many times to scroll). Should I do that before I flash to stock, or after?
I looked at this thread - http://forum.xda-developers.com/showthread.php?p=33570269#post33570269 - and there are a few ATT stock roms. Which do I need, does it matter?
Since I am unable to see my display, would like to flash without tripping counter. Which is the preferred way to flash back to stock and keep counter at 0?
Let's start simple then.
Should I flash back to stock if returning phone for insurance (not warranty)?
Tough crowd! Whew! Haha..ok, well, I guess I'm going to give flashing to stock a go. Could someone help point me in the right direction as far as which ROM I need. I'll beg a lil too - PLEASE!
Follow this tutorial, you shouldn't need to worry about scrolling:

OK, that looks like it'll restore factory settings. That'll work after I flash stock ROM. Can someone point out the proper ROM I should use?
You don't have to, read the entire thread. Kies downloads and installs the latest stock rom for your device, it detects from model and serial number.
You just have to plug it, follow the instructions and wait until it boots up stock unmodified.

I'll be honest, I only read the first post. I'll read through the rest. In the meantime, in case it doesn't mention this, do you know about flash counter? Mine currently is not tripped - does this keep the counter as unmodified? Also, last I remember Kies did not recognize my phone after I put custom ROM on there (kyanROM), so will that matter if trying to do it via Kies?
hey guys I'm having some issue changing my phone back to stock, i did some digging around and found some stuff on different models though. I'm on a t-mobile galaxy s3 sgh-t999, i rooted my phone to get WiFi tethering. found out later that the new jellybean firmware blocks it so its pretty much useless now. i unrooted my phone using mobile odin, triangle away to rest count and cwm recovery to do so. wiped cache partition and did a factory reset. the unroot was successful but my phone says modified now instead of normal or original like its supposed to. the stock rom that i flashed takes me back to 4.0.4 ics when it goes to download updates it stops at 4.1.1 after that i get a message saying my phone is modified and updates are not available. all i want is my phone back to normal like i just bought it, I'm thinking about exchanging it and I'm pretty sure they wont take it if the status reads modified. i read this thread about a root66_TMO_T889UVALL4 rom with odin that keeps everything stock and keeps the count at zero thought the whole wipe and boot process. is that something i could use on my phone? any info on how i can fix this is extremely appreciated guys thanks.
Do not flash anything.
Open the battery compartment of your phone, take the battery out, and tell us what the model number says.

one more question, like i said i just unrooted my phone do i have to root it again in order to flash the rom you liked me to?
You don't need to be rooted to flash a ROM.
Hi, I am sure there are countless threads out there already talking about the inconveniences that 4.3 bring and the problem you get for trying to downgrade. I have read through many of them and I think I have the general idea of how to downgrade relatively safely without running into the problems I am currently aware of. I want to confirm what I know. I would like to be informed before I do anything, especially something as dangerous as a downgrade attempt.
So all that I am aware of right now is that 4.3 brings in a new bootloader, attempts on trying to change the bootloader will result in hard brick, so does that mean any previous firmware that does not flash a bootloader will be fine? will stock firmware from sammobile work? I am looking at this one right now,
http://www.sammobile.com/firmwares/3/?download=16006
Second problem is 4.3 also changes the efs format, any modem before I think MG4 won't be able to read it, and you won't get network, this should be easily fixed by flashing the latest modem here
http://forum.xda-developers.com/showthread.php?t=1831898
...right? also the modems are made custom recovery flashable, if I want to use odin instead, do I just unzip and put the modem.bin into odin?
Also plans to root first and backup efs, I hear you have to go through hell to get it back if you lose it...
Doing any of those should trigger the knox counter...so basically anyone that still have warranty left and plan to use it cannot do anything...even rooting...right?
But that should be the least of your worries if you are determined to downgrade...
I am not sure if that is all the trouble I will run into, I don't know what made samsung so confident that they can even say it is impossible to downgrade, they meant to say difficult but you can do it, right?
also I am on SGH i747m bell.
Hi, I have just flashed Rooted Note 2 on 4.3 to the latest stock ROM which I downloaded from the SamMobile and now it will not register on the network.
The new version I flashed was the same as the old as i found it with the CSC N7100BTUEMK2 on sam mobile.
I checked the IMEI and it says 00499010640000 in status menu which is different from the one under the battery.
I did not perform a backup of anything as I was not worried about losing any data.
Any ideas what has happened to it and how to get the IMEI correct again?
I understand this is something to do with an efs file but in what way it has become faulty from flashing the same rom I cannot decipher
Any help much appreciated! :good:

From my experience:
1) Reflash the ROM.
2) Flash a custom ROM.
Both worked for me.
N7105 rocking AOSB with AGNi kernel,
Click "Thanks" if I was of any help!
Thanks, I have reflashed the current 4.3 rom UEMK9 and a slightly older UEMK4 with a DEMJ9 radio.
I have tried lots of radios - DM3, XXDME4, XXMI6, XXMJ5, XXMJ2, and some other modem.bin
From what I understand its when you go from newer to older roms that you get IMEI problems, so its prob useless to try pre 4.3
Its all a bit confusing to me and which rom has which radio seems like an arcane mystery.
It is quite possible that I flashed a same version 4.3 rom but my old radio was different and not knowing it was such a minefield on Galaxy phones I never checked that or bothered with a back up.
I may have to resort to paying the people at unlocksamsung online £26 to reset my IMEI
Can anyone tell me, is it just the radio that causes the IMEI problem and should I just trawl through flashing radio zips until my IMEI comes back so I can save the efs file?
BTY everything else seems ok SN is correct and wifi works fine, I just can't get on a network without my correct IMEI
Thx
i also have the same issue on my note 2 gt-n7100 and now phone does no respond to the touch post rooting and all..i am tired of rooting and unrooting the phone like 100 times allready and now my phone is stuck in loop
Hello,
I tried to flash custom ROM, but something somewhere went terribly wrong.
I did read some guides on flashing before attempting this and did make some precutions as well.
Such as creating ROM backup with CWM and copying efs folder with Root browser.
Unfortunately I didn't succeed with the flash. Now the phone can turn on, but there is no network service, and IMEI number is missing.
I tried to go back to my original ROM, but that didn't fix the problem.
I tried to gather as much information as possible, but it seems that information on this device is a bit outdated. For example, I wanted to try to flash back to stock ROM with odin, but most links with stock ROM are down. The one that isn't down only provides .7z file instead of md5,tar file that is required by odin.
The device works, just can't connect to mobile network.
Is there something I could do?
Before flashing anything else, what baseband and bootloader is on the phone? The imei may be missing because the ROM is too new for the phone's current bootloader/modem combination.
Bootloader version is T999UVDLJA
Baseband version is UKNKOWN
I have finally found stock ROM in tar.md5 format, which is compatible with ODIN.
The t999 is the aws version of the s3 according to this: http://www.gsmarena.com/samsung_galaxy_s_iii_t999-4804.php
This forum is for the i747 and i747m (the AT&T and Rogers) version of the s3.
If the t999 is like the i747, do not flash any ROM via Odin that tries to downgrade the bootloader as this may brick the phone.
This makes just even more complicated.
When I go to settings -> About device, under model number I have SGH-I747.
When I double check this with Samsung phone info app, under model number I have SGH-I747.
In the same Samsung phone info app under PDA version I have I747UCDLK3 and under CSC version I have I747ATTDLK3
t999 only appears when I enter Download mode via volume down + home button + power button.
What does the label under the battery say about the model #?
Label under the phone is SGHT999.
Wow, this phone is weird...
I read on the forums that there is chance to restore firmware of the phone with KIES, so I tried that. At first I entered SGH-I747 model number and serial number of the phone and it failed. But after that I entered SGH-T999 model number and serial number of the phone and KIES started to update the phone.
At the moment I have android V4.3
Bootloader T999UVUENC2
Baseband T999UVUENC2
PDA version T999UVUENC2
CSC version T999MBENC2
Phone seems to be unrooted, IMEI number is visible, I can call again, but the phone's factory mode is on.
It seems that I had a SGH-T999 which somehow was tricked int thinking that it is SGH-I747.
At the moment I would just like to have a stock ROM for this phone without all the T-Mobile apps, would that be possible?
Does everything see to work?
The easiest way to root and remove apps would be to flash a custom recovery, install supersu and titanium backup. Then use titanium backup to remove the apps.
Yes, at the moment everything works.
I can call, receive sms, use wi-fi as well as mobile data.
The only problem is that phone has factory mode on Yellow text on black background. And it is heavily loaded with T-Mobile applications.
So I guess this phone is T999 then, right? How could it be that everywhere it had I747?
By custom recovery you mean custom ROM?
You need a custom recovery such as TWRP: http://forum.xda-developers.com/showthread.php?t=1809313
Download the tar version that can be flashed via Odin.
Download supersu and copy it to the phone. Flash recovery, boot directly into recovery without letting the phone boot the ROM, flash supersu, reboot. Install Titanium Backup from the Play store, remove the apps.
Thank you for sticking with me in this thread!
Could you please explain a little bit more what is TWRP? From the link provided I understand that is is a application that helps with custom rom flashing and backing up roms?
Shouldn't I do this at first - http://forum.xda-developers.com/showthread.php?t=1771687
Boot into download mode. Do you see anything about warranty bit 1? If you do, that means you have already tripped the counter.
Root is not required to flash a custom recovery.
If you are only interested in root, follow the other thread. If you want to be able to flash custom ROMs and backup the rom, you need a custom recovery which will definitely trip the counter.
Do you have any warranty left on the phone?
Yes, there is 1 next to warranty bit. What does it mean for me that I have tripped the counter?
At the moment I would just like to get rid of factory mode and remove those unwanted T-mobile APPS. I think I will be done with Flashing for quite some time
I don't have any warranty on the phone, It has been in the family for quite some time.
It would be 0 if the counter wasn't tripped.
To bring it right back to stock, you could flash one of the prerooted ROMs from the other thread. Just make sure you are flashing a rom that has the same bootloader that is currently on your phone. Hopefully, the stock rom will remove the factory mode.
I understand that the counter is only important if you need warranty, yes?
I actually just found a way how to remove the factory so that is one more thing less to worry about
And I rooted the phone with odin using the link few posts back.
Now for the final question, I understand that this rom is something along the lines that I'm looking for? http://forum.xda-developers.com/showthread.php?t=2501303
The ROM looks nice as long as you are running the correct bootloader and modem.
Installing a custom ROM only requires a custom recovery. There is no need to root or remove apps from the existing ROM since you are going to wipe the existing ROM before installing the new ROM.
I read through the thread and I understand that I have to flash T999UVUEMJC modem before flashing the ROM.
I'm not sure where the bootlaoder of this rom is mentioned. Only place where boot loader of my device T999UVUENC2 is mentioned is in change log "-Rebased to T999UVUENC2".
The official T-mobile firmware is here: http://www.sammobile.com/firmwares/database/SGH-T999/
Notice the last few letters in the firmware PDA?
Based on your post on the first page (post #7) you are on the NC2 bootloader and modem, which are compatible with the rom you are wanting to flash. (See the second line under the Disclaimer banner.) NC2 is the most current firmware for the T999 listed on the page Audit linked to.
(one explanation for how your device was reporting i747)
Is it possible that someone else flashed the i747 rom to this phone? Either someone doing you a favor or a previous owner? I747 roms will work on the T999, I frequently see people commenting on doing so successfully. You just need to have comparable bootloaders and modems. That and if the rom dev didn't accommodate the device in the updater-script the user must edit the script himself. In the unofficial cm12.1 thread for the i747 people were doing this often.
So the bootloader version is always the same as the modem version?
I understand that in my case I don't need to flash T999UVUEMJC modem, since the one I have at the moment is newer?
That is definitely possible, although, how it came to be I will never know, since I personally didn't buy the phone. But this would explain a lot.
Could you please take a look at this thread, I created steps I plan to do in order to flash the above mentioned ROM. It would really put my heart at ease http://forum.xda-developers.com/galaxy-s3-t-mobile/help/one-rom-flashes-please-double-check-t3111443
