Very beta: expect bugs and performance issues. Keep the stock firmware on the card as the way back.
Install: unzip the -sdcard.zip onto the SD card's root (it holds Firmware/ with the image and an
ot_restore.txt that flashes it at the next power-on), or copy the .ptf into /Firmware and flash it
from Config > F1 Firmware (or the stock updater).
