PW4 Debricking PW4

[keitherz]

Hello,

Has anyone had any luck on debricking a PW4?

I recently acquired a PW4 which seems to be bricked its current state is:
- Stuck on tree with boy screen on startup
- When connected to pc, it gets detected but shows an empty drive (hidden drive with 0 bytes, on linux it shows as /dev/sdb with 0 bytes as well)
- I have accessed its serial port using 1.8v UART was able to access fastboot mode but the flash commands are locked, no recovery menu as it boots directly to "BOOTING DEFAULT" if I let the kernel load.

Was there any progress made on unlocking the fastboot of the PW4?
Or is there still a way I could do a factory reset on this device on its current state?

Thanks in advance!
