[LG V30 Questions & Answers] br0adband:
I really really do hate asking for help and 99.63757% of the time I can fix things myself doing the necessary research into the problem(s) and potential solutions, but so far this one has me stumped and I'm too frustrated with it to just keep starting over so I'm asking for assistance from anyone that might be able to help, so here goes...

OK, so I picked up two H931 V30's the other day for $100 (for both, actually), one is slightly damaged (glass damage just under the Menu/Recents button area) but it's 100% functional, the second one is pristine. I did the conversion to the US998 without any issues on the undamaged one since the damaged one is for my Wife and she has no need for root/custom ROMs/massive amounts of tinkering like I've been doing for 20+ years or so. Unlocked the bootloader without issues too.

So, I get everything done according to the WTF guide (very nicely done piece of work, seriously) and it's up and running without issues. But then I decide to check and see if Magisk has an update so, I scroll over, find the Magisk icon, tap it, and I get that damned message I always get about updating to the latest version, either choose "NO THANKS" or "YES" and that's when the problems start. This is Magisk 18.0 by the way, and I've attempted this with 18.1 as well, and even the latest 19.1 and it still happens like this regardless:

The phone then suddenly turns into molasses in winter as far as operational speed goes. It chokes, then it dies, then the Home screen resets exceedingly slowly as if it suddenly went from the powerhouse phone it is to 1 frame per second or something in functionality.

The phone heats up like crazy, then I eventually am forced to hold Volume Down + Power and force it to reboot, and it does reboot and gets right back into the OS like nothing happened and everything works as normal.

But I cannot get Magisk to do anything at all, the app itself apparently never loads, doesn't function, I can't update it or get it to run in any way at all. Everything else works, including apps requesting root which is given by Magisk as it should. I know that with the unlocked bootloader Netflix won't install by default, and I know Magisk is installed and functional because Netflix shows up in the Play Store and I was able to install it and watch a video and the Magisk Manager icon is clearly right there on my device.

I've done this like 7 times now and I'm not going to do it again for the moment, I'm gonna end up corrupting something from all the flashing I think and then doing it again, then again, etc. :)

On my V20 I had this issue in the past (not recently) where when I attempted to execute the Magisk Manager app it constantly asked me that question when it starts up and regardless of "NO THANKS" or "YES" or even if it's updated to the latest version it always asks me that damned question and I've never been able to get it to stop. But with the V20 the app does load and I'm able to access features of the Magisk Manager.

On this V30, I can't do anything at all and I always have to reboot the phone hard and I'm kinda sick of doing that. So I started over again an hour ago, everything is working fine for the 8th time except probably Magisk. I haven't touched the icon but it's installed, root is working fine, but I really do want to understand WHY this crap keeps happening and WHY I can't get Magisk Manager to run properly without crapping out the phone.

If anyone can help or offer some suggestions I'm all eyes (given this is a text-based communication medium, obviously).

Thanks, and have fun, always...
