Ok ! I finally arrive to do something.
There is a LineageOS Recovery here :
https://drive.google.com/file/d/1gYAVTitz5uSP5_MO4KkXdYOvPmIvC2oJ/view?usp=sharing
- Once you get it, boot your phone to fastboot.
adb reboot bootloader
- Then, install the LineageOS-recovery.img
fastboot flash boot_ab LineageOS-recovery.img
- Boot to recovery :
fastboot reboot recovery
- Erase your data.
- Go to Apply Update, then SD card and apply the Arrow zip file.
- Wait for it !
- When on LineageOS recovery again, reboot system now.
And, you got it !
