How to unlock phone

https://wiki.lineageos.org/devices/lancelot/install#unlocking-the-bootloader (requires windows only application).

NOTE: apps allows to install correct drivers for fastboot.


How to enter flash mode

Power + volume down while it is off, then you can flash it using pmbootstrap flasher flash_kernel; pmbootstrap flasher flash_rootfs --partition=super; pmbootstrap flasher flash_vbmeta (must be OEM unlock for this, see above).

NOTE: Fastboot entered via on my phone, fastboot entered via adb reboot fastboot run into different fastboot implementation (showed blue word FASTBOOTD instead of orange FASTBOOT), which did not have implemented certain oem commands, the log from windows application showed error when running fastboot oem device-info command.
