I did the following bootloader unlock to install official Lineage
https://forum.xda-developers.com/v20/how-to/root-h910-v10m-t3664500

I then did the 10/31 update via Settings -> Phone -> Lineage upgrade
It downloaded and rebooted me into TWRP
I installed the upgrade

Now I'm in a TWRP bootloop.
Going through now:
https://forum.xda-developers.com/v20/how-to/solution-to-fix-twrp-loop-t3563532
Will this happen every time I do an upgrade? It there a proper procedure for an upgrade?

Additionally, it seems long press of power doesn't do anything (like hard reset), ie when in bootloader and recovery. Is this normal?

Thanks in advance.

While in TWRP:

adb shell
dd if=/dev/zero of=/dev/block/bootdevice/by-name/misc bs=256 count=1 conv=notrunc

Reboot, and you will be fine.

In the future you might want to manually upgrade LOS....

Thanks.
Manually as in reboot into TWRP
Install Zip?

Pretty much what happened, when I use LOS upgrade, all it did was download and reboot me into TWRP.
I had to manually find the zip, wipe cache and install. (didn't do a full wipe) . Was just going up from 14.x nightly to 14.x nightly

The thing is, when you use the OTA feature of LOS, it is just like the OTA of stock. It writes a change to the misc partition informing it that there is an update to flash so that the next time the phone boots, it will boot into TWRP and flash it.

The problem is that sometimes (as was your case) misc doesn't get reset, so it keeps booting to TWRP thinking that there is an update to flash. That stems from the fact that LOS (IMHO) isn't even at an alpha level for the V20, and there are several versions of TWRP.

Long story short -- yes, download the zip manually, boot into TWRP and flash. Well, now that you know how to fix it, you can keep trying to OTA as well :)
