K5 Debricking Kindle PW

Hi, my Kindle PW is frozen and does not boot after hard reset and is not seen as a device when connected to a PC or MfgTool. I connect to it via the console - it cyclically restarts. It tries to boot a diags mode was unsuccessful because both partitions - main and diags were damaged. After that I switch to fastboot mode and flash the image and the kernel for diags partition, boot into diags mode, connect the drive via USB Device mode and began to copy the image to main partition, but received an error writing to mmc (after 70% writing of image). I tried using fastbot erase main and diags partition, but unsuccessfully – I again received an error writing to mmc. Then I typed:
fastboot eraseall
fastboot flash diags
fastboot flash diags_kernel
fastboot reboot
It was a big mistake - eraseall, now uboot is not available, log:
