Is reboot working? 按鈕需要長時間，30 to 40 sec.

有需要的話，用serial console, issue the command "rm /persistent/.unpacked

But I can tell you that it is not always working in IP01. Serial console is more reliable.

I am going to try to flash switchfin firmware sometimes in the next few days. Hope it works and will report here. Of course, serial cable on hand to ensure no problem,

Bubblestar has provided me a great page

The website told me how to fix a permission error. You can see my report and picture in other thread. It is now 9:00 hours up time. I will try to build a better equipped firmware.

But always need a serial cable.

A handy tool is puttytel, freeware to do serial console. Only problem in my desktop PC, serial port is still but now working. I have to move to other PC to do serial console.
You are right as long as boot firmware is untouched, you are safe to flash a new kernel.
