[Google Pixel XL Questions & Answers] Chancellor:
Hi all!

I'm not so called an "expert" on android. (I work normally on Linux ) so, my *final* goal is to install a custom rom on Google Pixel XL (marlin).

For the moment i'm trying to install the official google 8.1.0 (OPM1.171019.016, Feb 2018).

I carefully followed these 4 links:

I unlocked and rooted the "marlin" with no problems.

I installed TWRP (twrp-3.2.1-0-marlin): it works but seems do not persist and every time i want to use it i have to reinstall via fastboot (strange... what i missed?).

This is the guide followed: https://xdaforums.com/pixel-xl/how-to/guide-how-to-unlock-root-flash-pixel-xl-t3507886

I downloaded the official rom google 8.1.0 (OPM1.171019.016, Feb 2018) following these guides:

With flash-all-sh and OPM1.171019.016, Feb 2018 give me this error " fastboot too old " ( adb version revision 1:7.0.0+r33-2 )

If i write into shell this procedure at a certain point all stops and an error appears:

.......

OKAY [ 1.391s]

writing 'boota'...

(bootloader) Flashing active slot "_a"

FAILED (remote: partition [boota] doesn't exist) <----this

finished. total time: 1.801s

Please, what i did wrong?

how to recover this error?

how to make persistent TWRP?

Anyway, is it possible that the 8.1.0 version is too new for my configuration?

Thanks a lot for any advice!
