How to enter flash mode

When the device is booted, keep pressing Volume Up and Power. When the screen goes black, keep pressing the buttons for ~5 seconds, then release them.

Alternatively, you can run adb reboot bootloader from your PC when running Android.

Installation

Currently, it is only possible to install postmarketOS directly on the device. However, it seems the tablet could boot from an sd card.

First, install rkflashtool:

- Arch Linux / Manjaro: it is in the AUR

- Others: see rkflashtool GitHub repo

$ pmbootstrap init # Select klipad-rel device
$ pmbootstrap install
$ pmbootstrap export
$ rkflashtool w boot < /tmp/postmarketOS-export/boot.img-klipad-rel
$ rkflashtool w system < /tmp/postmarketOS-export/klipad-rel.img
