Another brick

A few days later after upgrading to Lollipop the tablet failed (Google apps reported failure and closing), restarted and didn't come back. I called a factory reset and then it ended up in the "Fastboot starting..." mode. I already tried the bios_repair suggested in this thread however it doesn't seem to work. After trying to flash any image it disconnects. I have tried in Win10 and Ubuntu on all 3 USB ports with the same results. On the tablet it only remains on "FASTBOOT CMD WAITING..." message.

These are the logs from Flash Tool (using the latest 5.5.2.0)

Tried to flash directly the stock ROMs, but that didn't take me further from the EFI failed screen. I'd appreciate if someone has more ideas to try!
