my French is not good, so I will write in English and translate with deepl:
Which Lineage Version did you install?
The current Version is 18.1 and this is no longer compatible with TWRP.
So I would flash the Lineage Recovery and then use this to flash Lineage
Quelle version de Lineage avez-vous installée ? La version actuelle est la 18.1 et elle n’est plus compatible avec TWRP. Donc, je voudrais flasher le Lineage Recovery et ensuite utiliser ceci pour flasher Lineage.
