Hi XDA World ;
I have a friend who is suffering badly with the AT&T version of 4.4.2.
The current stats are:
Stock, locked, stock everything.
KOT49H
4.4.2
I337 UCUFNI1
SGH-I337
I would like to unlock, boot custom, root, AOSP. (AOSP with root, can be rom with any 4.4.4 release that looks and feed is AOSP)
I will follow any known working instructions without heavy handholding.

I'm currently running on 4.2.2 Jelly Bean on my ATT Galaxy S4(SGH-i337). I want to upgrade to the latest Kitkat 4.4.2 Stock Update. My ATT S4 is rooted and unlocked to work in India.
Can someone tell me:-
- If I need custom recovery for this ?
-If Yes/ No how do I go about it ?
-Will I lose root & and Carrier unlock after update ?
- Link to the Stock 4.4.2 Kitkat OTA

If you update, depending on which firmware you are on now, you will lose your ability to boot custom roms. If you have the MDL firmware, I suggest keeping it as you can use LOKI to bypass the locked bootloader and boot custom roms and recoveries. Now to answer your questions.
You can use a custom recovery to update to 4.4.2 if a .zip file for the update is available. You can also use ODIN to flash the update. You will lose root unless you use a pre-rooted update file. The stock 4.4.2 update is in the General forums I believe.
Hello I have a question regarding my GS4.
I have an sgh-i337 on 4.2.2 rooted and unlocked with regionlockaway and was wondering if I could update to 4.4.4 without losing my unlock?

I'm 99% sure that once you are sim unlocked, you are good until you manually lock it again. Upgrading will not relock your device. In the off chance that I'm wrong, then NB1 base CAN be sim unlocked. Which is what you Odin before taking the latest update... http://forum.xda-developers.com/showthread.php?t=2595457
That said, if your 4.2.2 is base MDL or earlier, by upgrading you will PERMANENTLY lock your bootloader with no work around and be stuck using touchwiz based KitKat ROMs with safestrap recovery. (no lollipop, CM, or GPE)
Hello, everyone. I'm new to Android. I recently purchased a new Samsung Galaxy S4 GPE. I love the phone, but lollipop is very buggy. I liked KITKAT 4.4.4. I was curious if someone could help a new user in a step by step fashion how to downgrade my GPE lollipop to kitkat 4.4.4??? Basically how to root, unlock bootloader, flash rom, etc. I would be entirely grateful. Not sure where to start and do not want to brick my phone. God bless.
Really? I used a lollipop GPE based custom rom and it was the most stable out of all roms so far.
Anyway, you will have to look in the Google Edition S4 forum.
There is a guide in the S4 General Section on how to downgrade from lollipop. Don't know if it applies to GPE.
Hi,
As the topic suggests, I am going to buy a used S4. I checked two S4's both with stock recovery, one was on lollipop 5.0.1 and the other was on kitkat 4.4.2. The stock recovery of 5.0.1 was showing more options than the one on 4.4.2. Is it some thing implemented in the new lollipop 5.0.1 upgrade ?

It could be that samsung added more features in the new recovery. With every update, there comes a new recovery, bootloader etc. so this case is very likely.
If you are going to install a custom recovery anyway, then that doesn't really matter to you
I have the AT&T Samsung Galaxy S4
Android Version 5.0.1
Build I337UCUGOK2
I've already unrooted it.
My question is, can I install custom roms to it?
I read somewhere on xda that I can only install roms based on the base one using Safestrap.
I really wanted to install cyanogenmod, but on the page there's the warning ''you must be on build I337UCUAMDB or I337UCUAMDL or this will not work''
Any help would be appreciated.
Not possible without unlocking bootloader
I am in the same boat. Unfortunately at the moment there is no way to get CyanogenMod from OK2. I have spend so many hours trying for the same. The conclusion is that the bootloader is locked and there is no known method to unlock the bootloader on I337 yet.
