So, I currently have a samsung s7 active that I purchased used, unlocked but was using AT&T with the AT&T firmware on itat the time. I upgraded it to Oreo universal firmware
It's currnet running info is
Baseband: G891AUCS5CSB1
Android Version: 8.0.0
Samsung Experience version: 9.0
Android security patch level: February 1, 2019
How would I go about downgrading back to Nougat but the Universal firmware?
I'm quite new to the android system, and all the guides seem to have different steps to use and there seems to be a million firmwares for each version.
I was looking at the thread linked here, and there seems to be 3 of the same firmware that are all different somehow???
What would be the best, easiest, and quickest firmware to use and guide to follow? I want to go back to Nougat with the universal firmware and my phone to remain unlocked of course
any help is greatly appreciated. thanks!
the problem with this dam phone is the locked bootloader! snapdragon samsung sucks... PLUS it was exlusive to ATT
such a shame. a phone with an AMAZING camera even today and the BEST design for its time... only to be locked to AT&T, LOCKED snapdragon and really ****ty stock software super lame
because of this I'm not sure the thing can be downgraded
Hello, is that the case then? That the S7 Active can't be downgraded back to android v.7 Nougat ? I'm hoping that it can, as AT&T just forced the v.8 Oreo into my S7 this morning, and now I no longer have the very useful 'Usage Manager' app. =( I used it more than any other app, to enable/disable mobile data on the fly, and kill all running apps in background, etc etc.
Please let it be..... downgradable !=(

Hi Friends,
It's been an year since I decided to crack open my android OS and install an OS which was lot faster sans bloat ware. I chose to go with CWM recovery and Cyanogen. I was happy not seeing At&T logo while my phone boots up and was hoping much better things as I use this phone. However, no matter to which version I upgrade, CM has been extremely disappointing to say the least. Not to sound like I am whining, can someone guide me on how to get back to stock OS without bricking my device. My device details given below.
Model: AT&T Samsung Galaxy SIII (Samsung SGH-I747)
Baseband version: I747UCDMG2
Bootloader version: I747UCDMG2
Android version: 4.4.4
CM version: M10-d2lte (downgraded from M11-12 after issues with camera, call volume, mobile networks)
I am seeking help on:
1. Where can I get the stock ROM that suits my device current state
2. Steps on how to wipe off the current crap on my phone and install stock
Any help in this regard would be highly appreciated.
Thanks,
Sid

If your phone isn't unlocked and you are able to flash to stock 4.1.1, use the free method to unlock it before upgrading the bootloader.

Hi OP,
were you able to go back to stock ROM from Android ver 4.4.4 Bootloader I747UCDMG2?
If yes, please let me know which stock ROM you used. I am in the same boat.
Thanks
First off here are the current details of my device:
-------------------------------------------------------------
Model Number: SAMSUNG-SM-N900A
Android Version: 5.0
Baseband Version: N900AUCUEOC1
Kernel Version: 3.4.0-4335446
Build Number: LRX21V.N900AUCUEOC1
Knox Version: 2.3-------------------------------------------------------------
(Sorry I would have posted screenshots but I don't have 10 posts yet.)
I bought the phone with KitKat 4.4.2 and Baseband Version N900AUCUCNC2
Since then it has been updated through:
KitKat 4.4.4 - Baseband: N900AUCUDNJ5
KitKat 4.4.4 - Baseband: N900AUCUDNL1
and now Lollipop 5.0 - Baseband: N900AUCUEOC1
I carelessly updated my phone via Firmware Over the Air (FOTO) not knowing at the time that it would change the process for rooting the phone later on.
I have tried many tutorials and checked various threads throughout the forum for a solution but it just seems AT&T phones are extremely hard to root nowadays.
Some of the things I have tried without success are:
TowelRoot
KingoRoot
Root De La Vega
and possibly a few various other methods.
It is also possible that I may have done one of the above methods incorrectly, although I tried to follow the instructions as carefully as I could for each tutorial.
I have heard that it is easiest to root this phone while it is at KitKat 4.4.2 and I am curious if there is a way where I could downgrade the Android version and successfully root this phone. But I have also heard that AT&T patched 4.4.2 so that it was harder to root although I am not quite sure if this matters.
If anyone has any solution to my problem I would so greatly appreciate it. I want to be able to use this phone to its full potential before I get a new one.
With the 5.0 update comes a fully locked bootloader. ..which means no kernels....ever again. .
Downgrade is not possible to an older version. ..
No bootstrap recovery exists to my knowledge. ..and leaves you with no real root options. ..
Perhaps our devs could find a method. ...but support is not looking good for this older device.
You are locked up tight. ..
Very sorry. ...g
Sounds like you have a Note 3, not the 2.
What he said. Note 2 is i317 and has no lollipops
Well, I've been waiting for this to help fix my semi-borked phone and it is now available:
Android File Host Courtesy of the Motorola-Firmware-Team.
I know quite a few have been looking for it as well.
Now here is my issue if anyone can help -
Before I knew what I was fully getting into (this AT&T Z2 Force is my first bootloader locked device) I mistakenly flashed an oreo modem from the retail image to my 7.1 device. This gave me a missing baseband and IMEI, with no wifi or sim. In my attempts to fix it I flashed the modem from Tmobile (oreo) and eventually got wifi back, but not sim. I hoped going to the AT&T Oreo image would give me back sim/cell, but alas it seems the AT&T baseband version is lower than the current TMO on my phone, and both wifi and sim service are gone.
I feel like I need a way to roll back the baseband, but can't with the locked bootloader.
I can flash back to the TMO modem and get wifi, but that is all.
Any insights?
What was the ROM Oreo that you installed before installing the Tmobile?
The ROM that you downloaded is for moto z2 play not for moto z2 force
It is for the z2 force (Nash), just listed under the z2 play on Android file host for some reason.
As for your question, I'm not sure I understand - are you asking which rom I installed before going to the tmo modem? It was the retail Oreo rom, which obviously didn't fully install due to the locked bootloader, but started my journey to finding a working modem as anything 7.1 I tried after the failed retail flash would not work.
In hindsight I could have left the phone untouched at that point and waited for the at&t Oreo files, but I have a tendency to tinker too much...
I settled on the at&t 7.1.1 rom with tmo 8.0 modem for wifi. Now the at&t Oreo rom is available and installed, but it gives me a missing baseband unless I use the tmo modem. Oh well, suppose I will wait for the next at&t update at this point unless someone has any suggestions.
I have a Sprint version coming tomorrow so I'm not as bothered by it any more, and I'm looking forward to the unlocked bootloader.
I tried to download that ROM but do not tell me
When you say the numbering of the At & t ROM It is smaller than tmobile's
I just installed the ROM 8.0 from at & t is working very well, any news I will communicate, thanks for the information
I have a problem with this version the 4g LTE does not grab me
I am having the same issue, did you ever find a resolution for this?

No, unfortunately.
I have a second Z2 Force from Sprint which I use, and this AT&T version exists solely as a mini WIFI tablet. I'm hopeful the 9.0 Pie update will breathe more life into it eventually.

At&t
I have an AT&T 10+ still running on Pie.
I refuse to upgrade as it runs fast, very stable and I know Q would screw it up bad.
Lol, a virus be less trouble than Q
Be warned, AT&T's last phone updates are usually their worst.
The current software version on my lg g5 sprint is LS992ZVA, kernel version 3.18.31, android security patch april 1, 2017 and android version 7.0
I got this phone around two weeks ago. The cellular network signal keeps fluctuating, battery drains in standby mode. So, i would like to downgrade to marshmallow and want to see if things will be better.
I found some firmwares but they don't mention android version, only software version(zv8, zv5, etc) and i'm confused.
so please guide me to safely downgrade and marshmallow firmware and other working links would be very useful!
