I tried to flash the RileyRom 1.5.1 on my Pipo P9, but now I'm stuck: I can only enter TWRP (when the tablet is charging). Android does not start, and I cannot find a way to enable the recovery mode (the computer does not recognize the tablet).
Do you have any idea how to fix this issue? How can I load my Pipo P9 with RileyRom 1.5.1?
