[T-Mobile LG G6 ROMs, Kernels, Recoveries, & Other ] ryanrod:
Yeah I don't have a clue either. Even when my phone was flashed with the kdz, I had weird volume changes with maps and secondary sound sources, but not a limited volume issue. It would occur in a similar scenario to yours. If I started playing music BEFORE launching google maps, then the maps voice sound would be at a really low volume. You could increase the volume while the voice directions were being given, but every consecutive time the volume would go back to near zero. The only way to get those apps to work together is to launch maps first and get the voice directions going through bluetooth and only then launch a second source of sound (youtube/newpipe background/music player/etc). Then when it lowered the music audio, the voice directions were at a high enough volume as well. That is a weird bug in 11g I think.

I am going to keep trying different things including 11h, 20a, and using viper as well. I will let you know what solution I discover. Thanks for the heads up on the 20a procedure when using eliminators zip. I am going to try his C2 zip which is complete without laf.

Your software is legit, far from crappy my friend! I really like how you explain things in detail. That is something lacking on xda in my experience. Thanks for all your hard work. :)

Hmm I'll try this... Does viper work on 11g, 11h, and 20a? What are you running now? Thanks buddy.

weakNPCdotCom will probably have a better answer for you, but I might be able to help. If you followed the root procedure by runningnak3d, then you have TWRP on your LAF partition and you also have TWRP on your Recovery partition. This is actually a good thing because if one gets wiped or flashed over, you have a failover. Now because TWRP is on LAF, that is why LGUP will not see your phone and you are not able to install via kdz currently.

Essentially, you have three options to go to 20a.

1. Boot into recovery, format data, then reboot into recovery again. Wipe system/data/cache/dalvik cache. Flash the 20a bootloader without LAF (very important to retain recovery on LAF) and modem zips available from Eliminator74: LG-H872_Oreo-20a_Bootloader_B2.zip (WO/LAF), LG-H872_Oreo-20a_Modem_Only.zip (Safe Either Way). Then Then flash the 20a SysBoot zip w/Magisk from the 20a thread by weaknpc. Now wipe cache/dalvik cache again and boot into system. Then you are on 20a and have root.

2. Boot into recovery, format data, then reboot into recovery again. Wipe system/data/cache/dalvik cache. Flash the complete 20a zip available from Eliminator74 without LAF (very important to retain recovery on LAF). That is this one: LG-H872_Oreo-20a_Complete_C2.zip (WO/LAF). Then wipe system/data/cache/dalvik cache. Then flash the 20a SysBoot zip w/Magisk from the 20a thread by weaknpc over the one from Eliminater74. Now wipe cache/dalvik cache again and boot into system. Then you are on 20a and have root.

3. Flash the 11g StockLAF zip in this thread and then use LGUP to flash the 20a kdz. Then follow the whole root process from runningnak3d again.

I think that option 1 and 2 are easier and less risky since you retain recovery no matter what. The zips from Eliminator74 and weakNPCdotCom DO NOT have the stock recovery in them, so they won't flash over the recovery partition where you have TWRP. As long as you pick the right zips, they will also leave your LAF partition alone as well, which means TWRP stays on LAF as well.
