Is it possible to downgrade to older firmware on the Mate 9 from b190 to the prior ones? I want to see if battery life is better on the older stock rom. Do I have to root to be able to do this?
You can flash HWOTA method for downgrade firmware.

is there a root for this version?
i just dont want to brick my phone.
thank you in advance.
no root possible on 20K or any other version, except 20A. only way to get root on the H830 is to all of the following steps:
unlock bootloader
downgrade to vesion 20A
install TWRP
install supersu
I did it 2 weeks ago and took about an hour.
Thought I'd ask again after month or so.
I am on 20a , TWRPED, rooted , BL -unlocked.
How do I properly downgrade to 10j MM? It has the same 01 rollback version so it should be doable right?
Thanks

You can flash any ROM ARB01, 10J - just like that, so you can!
How would you do this? I have a h830 with Oreo, and I can't install TWRP or flash anything at all.
I followed the instructions to roll back to 20a using LGUP, but have not had any success. When I attempt to flash TWRP, I get the message like "remote command unknown".
Don't know how to troubleshoot why the rollback is not working. Any advice or links?
Is there a way to install a custom ROM on a LG G5 running stock Oreo? Can the stock firmware be downgraded to one of the stock nougat builds to help with bootloader unlock and TWRP install?

Yes, you can downgrade 30c to 20a, then unlock bootloader and install TWRP.
Is there a guide on how to do this? Thanks
I never found a solution to this and ended up getting a new phone. But that new phone just brokeand I am back to using the LG G5 again.
So now I am looking for a way to downgrade to 20a and the files needed to unlock the bootloader.
Appreciate any help provided.

Hi subaron what version are you on now? If you are on the latest 30C then you need to downgrade to 20A stock ROM first.
You must download the 20A kdz file and flash it with UPPERCUT. Then you enable Developer Options and can follow the info in this thread on how to install TWRP recovery and root. The only thing different from those directions is: instead of SuperSU, install Magisk.
Once you have rooted 20A with TWRP installed, then you copy the 30C COMPLETE .zip to the sdcard, reboot into recovery, and install that and install Magisk once again.
