Hey guys I am trying to update my galaxy s3 to kitkat. I am running galaxy s3 at&t variant 747 rooted 4.1.1. I747UCDLK3 update to kitkat. I realized I need to update to 4.1.2 first before doing the 4.3 update. I can't seems to find files I need for 4.1.2. Can someone point me in the right direction. Thank you for your help.
Are your running stock 4.1.1? If you are and your phone is not sim unlocked, unlock it using the free method. Once unlocked, use Odin to flash back to stock unrooted 4.1.1 and then run OTA until you get to KK. It's a longer process than trying to flash straight to 4.4 but is a safer method for people that are new to flashing ROMs.
I am on the stock rom 4.1.1. Does CWM recovery need to go back to stock as well? That is a good idea to unlock before I update.
If you flash back to stock 4.1.1 with Odin, it will wipe everything and put the phone back to completely unroot stock and stock recovery. Stock recovery and being unrooted is required for OTA updates.
Ok is this the link to unlock phone?

Yes, that's it.
I can't seem to find 4.1.1 rom file links seem to be bad on unlock page.
There are stock rooted 4.1.1 images here: http://forum.xda-developers.com/showthread.php?t=1739426
You can use the free unlock method even if the ROM is rooted.
For some reason the at&t mirrors don't seem to be working either.
Mirror2 for the stock rooted 4.1.1 works for me.
I would like to root again after kit kat Is it easy to root with knox? Does unlock stick through kit kat? I really appreciate all of the help. Great website. Great people.
Many people have had success with rooting by using Towelroot.
The sim unlock is permanent.
Let me know how it goes for you @thepar. I expect to be updating to kitkat in the coming week.
For the benefit of those searching the forums to unlock their phones my experience may be of help to those on 4.1.2 or possibly even MJ2. I have had my SGS3 since June 2013 and only allowed one update, that was to 4.1.2. My phone was rooted long ago, but I just unlocked it earlier today and that was with a custom recovery in place and without unrooting. In my case I did not revert to the 4.1.1 rom. I did downgrade the modem to dlk3, that of 4.1.1 while leaving the rom and bootloader at MG2. After completing the unlock I upgraded the modem back to MG2. I have confirmed that SMS, MMS, phone, and wifi functionality is intact.
In truth, I will probably not go back to stock to get to kitkat. I am considering upgrading to the leaked MJ2/4.3 bootloader and MJB modem and then flash a kitkat rom which will work on them, there are several.
I just did the unlock yesterday. I need to find someone with a t-mobile sim to test if the unlock worked. Will I still be able to update the OS even though it is on rooted stock? What will it update me too?
I am kind of debating if I should install a custom rom minus KNOX.

If you want to run an OTA update, you need stock recovery and an unrooted system.
I have a stock recovery but the os is rooted. I don't mind using oden to update the os. I might be better to install a rom with knox removed. I can't seem to find 4.1.1 stock unrooted. I did find 4.0.1 ICS.
You can find a stock ATT 4.1.1 ROM on sammobile.com.
You cannot use Odin to flash a stock KK ROM because it was never released in an Odin format by ATT. ATT provided the KK update via OTA updates. Complete KK updates were provided for i747m only.
Thanks so much!! downloading now.
Let us know what happens. Cheers
I have decided to go custom rom route. It is better to update stock ota first then install custom rom or custom rom straight from 4.1.1?
Updated my firmware yesterday from 4.2.2 to 4.4.2
after updating, i lost my root. i tried rooting my SM-T215 again from www .mgyun. com but it can't be rooted.
anyone out there with any clue?
Hello guys, I have issue with GPS and 4G network, I have 5.0 official Lollipop flashed with Odin and I want to go back on KitKat 4.4.2 to update it again on Lollipop via OTA. Cause first time when I have done it from 4.4.2 to 5.0 via OTA everything worked great. Can anyone help me with tutorial?
Hi my friends, I am looking for a STOCK RECOVERY for my LG G Pad F 8.0 AT&T (V495). I was trying to do an OTA upgrade to 6 but after the Download and restart the installation is giving me an error because i am ROOTED. I need to flash stock recovery to be able to install new OTA upgrade to Marshmallow 6. Is someone have a 5.0.2 STOCK Recovery or maybe another idea on how can I do and upgrade to Marshmallow 6 I will appreciate any help. Thanks
Is there a KDZ or TOT available for your variant?
I am in the same boat. I can not find the stock rom anywhere. I would like to upgrade to to 6.0. I am rooted with king root. If the stock rom is not found is there a way to unroot and delete all root files so the update does not detect the root so we can update?

In order to take OTAs (starting with Lollipop) you have to never have been rooted (since the most recent time you've flashed a KDZ or TOT).
Unrooting isn't enough.
Hi there, just factory reset my i747 s3 att phone. i am on 4.1.2.
Should I root first with chainfire easily or should I update first? I dont even remember how to update this phone from stock. I would like to be at 4.4.2 or above (or are any of the newer versions good, 5/6 etc?) with root and xposed installed in the end. What should be next steps be?
thanks!
Moved to Q&A
If the phone is not sim unlocked, I would flash a stock 4.1.1 ROM from sammobile.com using Odin and use the free method to sim unlock. I would then run OTA updates until the phone is running the latest stock ROM. Running OTA updates is the slowest but easiest method to get the phone running the latest modem and bootloader. Many recent custom ROMs require the latest bootloader and modem to function.
