LG V20 H910 Unlocked phone, rooted and updated to 8.0.0 but issues?

[markm75]

I have the h910 which is unlocked (i put a tmobile simcard in initially, which is actually prepaid).. i tried the ota check for updates to get it beyond android 7, it says no update available. I had wifi enabled and connected.

I figured the issue is that its a tmobile prepaid issue, since i guess technically the phone is att branded.

So i took my galaxy s8 att sim card and put it in, waited till connected.

Once connected after about 30 mins i tried again, still no updates available?

So i'm at a loss on the OTA portion.
Is there a way to get that working?

If not, which method should i use to force it on, so far i started following the steps on this page:
https://www.getdroidtips.com/lg-v20-android-8-0-oreo/
Which is really only android 8.0 not 8.1.

(I also tried check for updates from the lg bridge, but it throws an error even with mtp enabled on usb).

Thanks in advance

update, i tried the 20F firmware on that page which says us99620f, but i got an invalid kdz message when i tried LGUP to flash it.

LGup says H91010m for the version.

Question on the process for oreo

I have the recovery twrp-3.2.3-0-h910.img installed.
I folllowed the steps and installed:
H910_20h_Oreo_full_rooted.zip and added zips for H910_v1.0-mk2000.zip and what i thought i needed, SR5-SuperSU-v2.78-SR5-20161130091551.zip but now realize supersu is outdated, so at this point only mk2000 is on there.

The phone appears to be up to date and on oreo. Initially the free root checker seemed to say it wasnt rooted, but on second run it show it is.

I tried to run magisk manager but it says unfortunately magisk manager has stopped.(edit possibly related to the fact i didnt add any magisk 17.2 as a zip to flash, actually unsure where this file is located? can i do this now after the fact or does it matter)?
So at this point i think i missed something, maybe not fully rooted?

Questions are: does it matter if its not rooted? Will certain oreo features not work? Or, is this some isolated issue with just the manager not wanting to run?

The OS shows 8.0.0 (so i guess not 8.1), software version h91020h *i also tried to do volume up plus power did the factory wipe, but the twrp menu no longer appears, it just formats things back to stock 8.0 welcome

The system is pre-rooted but as they said, you can still flash the Magisk image.

As for me, I installed Magisk from the image I downloaded here magiskmanager[.]com

In order to get the TWRP back, you'll have to boot in fastboot mode through ADB (adb reboot bootloader) or volume down + plug to PC)
Then you can install the latest version of TWRP on fastboot mode: fastboot flash recovery twrp_image_file_name.img
