PW3 bricked pw3 need help

[lajki]

Hello,

My pw3 has been bricked, I am unable to restore working firmware.
I have tried uploading many different firmwares via serialport.
Unfortunately it usually ends with an error: 4

There is one firmware that starts installing and ends after time with another error:

I also tried to upload firmware by logging into root account and through dd overwrite rootfs and uImage after that device stops on tree image

Does anyone have any ideas what else I could try?

Have you tried selecting the "initializes partition table" option? Are you sure you have a PW3? What is the beginning of the serial number of the device?

Yes, I tried. I also used Erase MMC0 option after which I lost access to diags but I still have recovery menu and fastboot via uboot bist
