Sort of in a ROM fiasco...

[Androidlicous]

Hi guys,

I'm a young and stupid 14 year old who decided to install a custom recovery and flash a custom ROM. However, when I flash a stock firmware on my phone via Odin, in a Salmon color at the top, it reads, "FAIL!". I downloaded a firmware from Sammobile.

Hello and welcome to Android Central Androidlicous!

Have you ever been on the latest Lollipop firmwares for your AT&T phone, G900A, prior to your flashing attempt or have you always been on Android 4.4.2, KitKat?

So, were you already rooted, as normally, AT&T push updates out and there is no escaping unless you are rooted.

 

[Androidlicous]

I was already rooted.

Have you got a link to the ROM that you are on and to the custom recovery you are attempting to flash.

 

[Androidlicous]

I'm currently on Safestrap custom recovery, flashing wasn't necessary for this specific custom recovery.

ROM ; DeOdexed/Extreme Debloat/Android L features, I can't post links as of right now. The ROM was by elliwigy.

Follow this guide to safely unroot and flash a stock AT&T firmware, Android 4.4.2,NCE...

Unroot and restore AT&T Galaxy S5 back to stock firmware with Odin

This should get you back to unrooted stock AT&T firmware. I checked your existing custom ROM details... [NCE}{SafeStrap]DeOdexed/Extreme Debloat/Stock/Android L Features and there is no mention that it alters the .PIT files, so the stock firmware flash should work.

Thank you for answering, I'll try this when I get home!

Congratulations Androidlicous!

Unless you re-root your stock firmware, good old AT&T will push their latest stock Lollipop firmware, with the mega locked down AT&T bootloader, to you.

As for obtaining the NG3 firmware, that's a Google search job I am afraid as the AT&T clone firmware is not released by Samsung and AT&T do not share their firmware through the usual sources like Verizon do.
