It will stuck after Progress 100.0%, but it seems that not all partitions will get stuck. For example, lk partition can be written normally.

You should provide a --debugmode log, I have a hunch you have some relevant details in there. Are you able to read the same slice of memory?

EDIT: I'm having the same problem with my MT8781 device, but this is because my device has DAA enabled and I can't patch the bootloader, so I'm using the stock one. (and I've tried patching writeregistry to use the built-in command, but had no success with that)

If given the opportunity, I will try. Thank you for your guidance
