How to upgrade custome ROM to OREO? - HTC 10 Questions & Answers

I have bootloader unlocked, S-ON, run custom Nougat right now but I want to upgrade to some of the custom Oreo or Pie ROMS.
How can I do that???
Flashing through TWRP (latest version) just gives me a boot-loop.

What should be done to install lollipop on the device​
Bootloader being LOCKED or RELOCKED is not a requirement for OTA.
You need stock ROM, stock recovery, and that is all. Root is okay, and unlocked bootloader is okay (but LOCKED or RELOCKED will also work).
You sure LP has rolled out for your version of the M8? What version is it, and what region are you located?

No, you do not want to do that (install a 5.0 stock ROM with a current 4.4.4 setup). Reason being, your firmware will not be updated to Lollipop firmware.
What you want to do, is go to the stock backup thread, find the stock 4.4.4 ROM and stock recovery for your CID. Restore stock ROM and flash stock recovery, then OTA to 5.0. OTA will update your firmware. This is assuming your CID has rolled out Lollipop.

Hello, I want to update the firmware from 2.41.401.4 cid_34 s/on to the latest oreo one.. I have a custom rom right now.. and want to understand what my options are

Going to Oreo you should wipe data so the best and cleanest way to do this would be to flash the 2.41.401.41 ruu. After flashing this RUU your phone will be completely stock. After that just take the OTA to Oreo. If you want to flash a custom ROM you will have to flash the latest twrp followed by ROM.
RUU can be found here.

Thanks so much both of you, I was on 1.53.401.13 and was having a nightmare trying to update my phone using windows!
I put the rom on my SD card and updated, just waiting on the OTA update now. Very very happy and relieved it all worked fine!!
