Cant restore stock firmware on Nami

I tried the script to install Full UEFI BIOS on a Acer Spin 13 (Nami / AKALI360) and installed Windows and it was working great but I needed to start it without the battery or wont even start… I tried to revert to stock firmware, the script worked well flashing the backup I saved before but now im struck at Recovery Mode. It looks like doesnt boot any USB or SD Card. I already tried to Esc+Reload Reset, and power up without power 40 times…

You need a USB Stick with the right ChromeOS recovery image, only it will boot with stock firmware
