Fairphone 2 LineageOS 15.1 (Android 8.1) Installation Error

[Shnoulle]

With a new phone, i have to use twrp-3.2.2-0-FP2 to install lineageos, maybe same for you ?

Twrp 3.2.3-0 OK, lineageos not OK

OK, seems there are an issue with last twrp and version control of phone ? I install previous twrp (twrp-3.2.2-0-FP2) , install last lineageos without issue after reboot computer + phone. About unauthorized : it’s in twrp, i use adb to send lineageos zip, but suddenly the phone seems to reset connexion, before rbotting (on twrp) : seems to be unauthorized
