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!

Pretty much as the title states, is it worth updating to marshmallow from kitkat? My phone has been running incredibly slow, and maybe it's time for a factory reset but should I just update to marshmallow? Thanks for your feedback.
My wife's Note 4 is having serious battery issues since it updated to Android M (as are others according to posts here) so I would recommend holding off until it is patched.
So i saw that samsung is releasing a firmware update for the Note 4 to N910FXXS1DQC3 which is 6.0.1 European firmware, more info here https://www.sammobile.com/firmwares/database/SM-N910F/ , my wonder was with the 150 or so security patches in this update. Im running EmotionOS which has its own firmware requirements so i cant just change firmwares but some of the files should be useful somehow right?
If you're on an old firmware -it is probably worth updating - It is quite good for a stock rom. I'm using it myself.
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.
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 !=(
I just bought sprint lg g5 phone which was unlocked(i dont know if it's officially unlocked by sprint or from other methods). Cellular and data is working. hotspot is working good(after i created data apn). The phone was on android 7. I downloaded update only once(which to my amusement caused great heating) and then the software was in zva. Then i read in some threads that updates above zva is not safe(i was lucky i viewed that thread at right time).
So, i have some few questions. Can i downgrade to marshmallow? Are there any advantages of marshmallow over nougat firmware(like battery life)? Can i safely root? What are the chances of hard bricking or other problems if i tried to downgrade from zva firmware?
