Thanks for the write up. Are there any instruction to force the device to enter EDL mode?

I have used the wvthoog.nl instruction (here is the archived version: https://web.archive.org/web/20260220053304/https://wvthoog.n... )

I got it working and can ssh in, till I delete the hotspot connection following the instruction on the site:

nmcli connection delete hotspot

Now the device is bricked. Well I guess linux is running on it, but there is no way to get to it. Any tips? I have used the instruction on wvthoog.nl but they didn't work.

Once you flashed the debian, edl is gone, go through recovery in fastboot mode, if it stills fails, do the hardware recovery by short USB D+ to ground while plugging it in.
