[LG V20 Guides, News, & Discussion] partyman66:
Thanks so much for the thorough walkthrough... I really appreciate it!

This was exactly what I was planning on doing but I was just a little curious about whether or not i would have to fastboot flash for the recovery to be restored after the stock recovery came in with the new Oreo install. I did my install at work tonight while in the middle of doing other work tasks, so I don't have a PC handy here that I can install random stuff on (like LG drivers and fastboot) to use for that if I needed to get TWRP back in that way while here. This is my first time using Magisk as well, but it's a fairly seamless conversion from SuperSU as far as the process and interface of the manager (thank God!).

Most things that I've tried so far seem to be working OK with all my typical customization and heavy debloating with the only real anomaly being the "staticy" screen during the LG-Boot error phase. I had a hard time getting WIFI tethering to work on Oreo. Ended up having to do a combo of previous workarounds such as tether_dun_Required = 0 global setting and changing tether_entitlement_check_state to 0 in /data/system/users/0/settings_system.xml while also adding DUN to my APN config. My tethering isn't that fast this way from a client perspective (presumably due to emulating Dial-up-networking), but it works well enough for my limited needs. I can provide greater detail on this to get free WIFI tethering on H910 if anyone needs it (I'm on Cricket, but i presume it also works the same for AT&T and possibly even TMobile).

I made a backup after I had a stable install with all the hard changes in place so now I'm going to experiment with XPosed and see how it works on Oreo. It would be nice if Amplify works on Oreo. It sucked how that never worked on H910A with Nougat. I'm curious to see how my idle battery drain is on this ROM compared to before. My idle drain was pretty unimpressive on Nougat even with a full debloat and Force-Doze\Greenify with XPosed modules install and most of the Google Apps frozen and all app data updates set to manual fetch rather than push or google GMS listeners active for chatty apps.

Update: It looks like KA-Mod-Reborn KCal screen color customization is not working. It will work if I change it manually but never reapplies itself after a reboot. I ended up applying custom RGB settings through LUX Autobrightness with KCal features enabled instead since it seems to work and stick when done through that application. I also am not able to get Youtube AdAway to work on Oreo.. it just keeps crashing Youtube regardless of which of the approximately 9 different versions of Youtube that I've tried, so i switched to Vanced Youtube. Apparently Amplify requires SuperSU and is not Magisk-compliant, so I never bothered even trying that. I also noticed that badge icon counters are seriously messed up for some apps. I'm using Textra as my messaging app and it shows "1" as the number of unread messages in the badge icon anytime I have 1 or more unread messages rather than the actual number of unread messages.

Everything else seems fine though.... GPS, Sound, Camera, Micro-SD access stability, Network signal, calls, texting, overall responsiveness of the system. Battery life still sucks but it's about the same as Nougat I'd say so far.
