[Q] AT&T S5 Downgrade 5.0 to 4.4.2 - Galaxy S 5 Q&A, Help & Troubleshooting

Hi, I am trying to downgrade my S5, SM-G900A, from Lollipop 5.0 to KitKat 4.4.2
I tried using Odin to flash the firmware but it failed. I read that there is an issue with the AT&T bootloader being locked. Was wondering if there were any updates on a workaround. Thanks

Nope, after 5.0 ota goure stuck there, for now at least.

Firmware advice ANE2 or ANCE 4.4.2

Hi guys i wanted some advice on firmware/towel root please.
I got my s5 g900f on uk vodafone running Lolipop 5.0 BNL9 firmware.
I want to downgrade it to stock Kitkat 4.4.2 using odin so that i can use towel root to root it with knox 0x0.
I read there are 2 official stock Kitkat firmwares that towel root works on, ANCE & ANE2. Therefore i need to flash either.
Can someone please tell me which firmware out the 2 above is more stable and has better battery life? Should i flash the ANCE which is the official out of the box firmware or should i flash ANE2 which is the 1st update that came to the device?
Also could someone confirm that after the downgrade, if will i have any modem or wifi issues? Thank you

SM-G900T3 Downgrade to KitKat?

I just got a Galaxy S5, and it came with Lollipop installed (5.1.1). I'd like to downgrade it to KitKat (4.4.2) but no KitKat Firmware for this exact model is available. However, there is 4.4.2 Firmware available for the SM-G900T and the SM-G900T1. Would the Firmware for one of these models work? Thanks.

I'm on 5.0 bootloader and i need to install this 4.4.2

Hey guys
As we know The 5.0 update for our note 3 drains battery and wasn't as good as kitkat
So i'm thinking about rolling back to the kitkat but there is a risk that imei could be lost
So i'm on 5.0 bootloader and running a N5 5.1.1 Ported rom
Is That safe to Flash this 4.4.2 rom

It's a stock rooted 4.4.2
For sure it's N9005 Snapdragon variant
It should work, I flashed miui and didn't loose my imei

Is there anyways to unlock bootloader of shv-e330s?

I want to downgrade to 4.2.2 but I can't find the PDA in my phone only the 4.4.2 has the exact PDA in my phone, I was downloading some stock firmware on sammobile and Samsung updates but still only 4.4.2 has exact to my phone and there is no 4.2.2 available for my phone, so I've read some forums that GT i9506 is bootloader unlocked and the i9506 and I've heard some people that shv -e330s is same with i9506. And other variants of s4 is bootloader locked. So is it possible that I can downgrade 4.2.2 from 4.4.2? My s4 is shv-e330s
This was my phone firmware:
