Hi, I got a pipo m9 max from my friend, it came with a ciclone voyager 2 android 4.2.
Triyed to update to Riley rom, but got BLACK SCREEN ON DOWNLOAD MODE, and my windows do not reconize it in download mode.
Im able to go to revocery, but when try to flash from there got INSTALATION ABORTED.

Triyed the TPW from arc aplication, and same result.

DO I miss my bootloader? How do I upgrade onte? Got acess to terminal emulator BUT CANNOT ACESS ADB FROM PC.

got no device on ADB DEVICE

Any help? Thanks!
