How to enter flash mode

Installation

Use pmbootstrap to build your own installation image.

$ pmbootstrap init
$ pmbootstrap install --android-recovery-zip --recovery-install-partition data
$ pmbootstrap export ./

Flash the generated .zip file in TWRP. Adb sideloading (in TWRP) is also supported. Other recoveries are untested
