I upgraded to S6 so i want to hand down my S4 and want to make sure i don't brick the phone.
i want to restore back to 4.2.2 MF9 unrooted and stock recovery and let the phone OTA to current version.
iirc phone is running unlocked bootloader version (MF9?) phone info:
SuperS4 ROM (L720VPUFNAE) Android 4.4.2 running TWRP recovery
Bootloader Version: L720VPUMF9
Baseband Version: L720VPUAMF9
PDA Version: L720VPUNAE
would be helpful if someone can post a link to the correct file i need with unlocked bootloader that will restore my phone to factory. tried one from the sammobile website but it's painfully slow.
TIA.

What I need help with:
Be able to flash a tmo rom that has working wifi calling either 4.4.2 or 4.4.4, Rooted stock type rom ok. Tried flashing a few roms but got boot loops or no wifi, had to restore at&t rom from safestrap backup. Need help to find out if flashing new baseband will keep tmo bands. What basebands can be used or modified for tmo bands. What Rom can I use with what baseband? No problem using odin also if needed. Tried searching for 2 +days. many answers alluded to but not clearly, thanks for looking.

I currently don't have acces to a computer so I can't use Odin to update the baseband and boot loader. I am running the latest alexandr kitkat rom (nj2, with bootloader nj2 and baseband ni3). I wish to update to the latest alexandr lollipop rom through normal rom flash from recovery.
Is there anyway I can update all the other necessary firmware parts directly from the phone?
Mobile Odin doesn't work any more?

You have to use Odin for Bootloader and Modem updates.
Also i would stay on NJ2 with your current modem and bootloader, i downgraded to it a few months ago due to the amount of bugs in the 'official' lollipop firmwares. I have tried the latest version, but still the same bugs.
Mobile data drop outs, extreme lag on recent apps.. random 'system is not responding' message that heats the phone up instead of turning it on, and many more.

well im not sure which way would be easier i would think downgrading and re rooting but if you choose not to you can always just reroot it even on lollipop there is a new way to root no matter what version you are on also check and make sure you have busybox and supersu installed it may have gotten deleted somehow and that could be why your phone is saying you dont have root
There's not much point in re-rooting if you plan to download an update to lollipop, because the update will immediately un-root you.
Just use Odin to flash a factory image, then follow the rooting instructions for whichever version you decide on.

so, i just got this phone: i337 on 5.0.1 with baseband i337UCUGOK3.
I have read a bit on xda.
Is it true that i will not be able to in any of the custom 7.1.1 rom on this phone?
Nougat can't be installed on a phone with a locked bootloader.
Here are my phone specs
Samsung Galaxy S4 AT&T Android Version 4.4.4,
Baseband ver. i337UCUFNJ4,
Build # KTU84p.i337UCUFNJ4
So far, I have successfully rooted my S4 device using this guide
Link: https://forum.xda-developers.com/ga...to-root-i337ucufnj4-4-4-4-11-13-2014-t2939553
So far, this guide worked out well. I wanted to install Lineage OS and TWRP. I downloaded the TWRP app and flashed to recovery. Everytime I reboot my phone, there is a samsung logo and underneath the logo is a unlocked padlock. When I boot the device in recovery mode (Home + Volume up + Power button), I am prompted an error saying "System software not authorized by ATT has been found on your phone". The phone boots perfectly normal if I don't go in recovery mode.
Need help on flashing my phone back to normal to its factory stock to retry this again.
The phone has a locked bootloader. It cannot run twrp and cannot run a custom ROM unless that ROM is based on a custom ROM.

If the bootloader is locked, how was I able to root the device?
Rooting affects the ROM, not the bootloader.
There are several phones with a locked bootloader that can be rooted.

Can I downgrade the software from Android 4.4.4 to 4.4.2?
I'm not sure if you can downgrade from 4.4.4 to 4.4.2 as I've never had an sgh-i337.
Was in a similar situation as you, so what I did was use safestrap to run Thor Rom, you can't downgrade to fix the bootloader nor install roms apart from those Touchwiz ones. Heads up about the Thor rom one: clear the data from the download manager before trying to download stuff from the play store. If you got any other issues with the rom feel free to ask (My S4 broke a while back though)

Hi
I want to downgrade my Android 4.4.4 to Android 4.4.2 because there are more ROM options for 4.4.2 touchwiz. Is this possible on the att s4?

On step #4, how do you install the ATT Kernel Modules?

It should be, 4.4.2 is the lowest you can downgrade to. I'm not sure exactly but it might be done through Odin
