I got the same error when I was following the instruction to upgrade Android 7.1. I am not sure eMMC empty or not the system is in MASKROM mode. So far I couldn't find any instruction how can I fix this mode and return to normal.

Any help appreciated.

MaskRom mode is the bottom line preve ...

It was already MaskRom Mode. I followed http://wiki.t-firefly.com/index.php/Firefly-RK3399/Boot_mode/en instruction and successfully flash Android 7.1.

I am not sure if the upgrade process is deleted Linux OS or not. If not there is no option in new Andorid 7.1 version that allows me to switch the OS. Any suggestion?

--- Instruction I followed to continue during Andorid Upgrade to recover MaskRom Mode---
Keep device power on.
Use micro USB Type-C cable to connect host and device together.
Press and hold RECOVERY key.
Shortly press RESET key.
Release RECOVERY key.
Note:If device still can not be found after pressing "RESET", then try this: long press "PWRKEY" after short pressing of "RESET", before finally releasing "RECOVERY".
