I am not able to alter any variable (except Date) or boot from USB. Firmware update also not working.
Disabling Secure Boot, Reset to Setup mode, Restore Factory keys or restore to factory defaults show no effect (after reboot settings are the same, efi dbx database still filled up).
Tried also Windows EasyUEFI and Ubuntu efibootmgr.
What is the correct solution to install and activate the EFI shell?
In my opinion the EFI NVRAM is full or defect and the bos not able to handle it correctly or provide a solution for cleanup/fix.
PS: would it work to Flash the SPI IC on the board in place without desoldering with my Miniprog?
I can live with the situation but it is highly uncomfortable not being able to boot from USB stick.
