Amazing work and it's exactly what i been looking for 👏

i just have an issue with a RK3399 board

i can only boot into MASKROM Mode through a hardware test points

RKDevTool can read the mode but cannot excute any of the commands available

and i don't have the firmware

so i managed to get another working board and dump the firmware out of it and flash it on the other board

Rockchip device is not in MCS or LOADER mode

How can i switch from MASKROM to MCS or LOADER Mode?

Thanks Anyways.

EDIT: if switching isn't possible, i can boot the other board normally, can i switch to LOADER mode from adb and dump the firmware into single flashable img file to flash it into the other board through MASKROM Mode? if so, can you please instruct me on how to:

1-Reboot into MCS or LOADER mode from adb.

2-How to Dump the firmware into Flashable IMG File to use in MASKROM Mode.

Update:

I could reboot into LOADER mode on the working board through adb and i tried to dump the firmware to test dumping process but it fails and here is the log:
