Hello I have at my disposal a Jetson Nano emmc 4GB module, which refuses any attempt to flash: Flash
error log output:

I know that on this module fuses have been burned. (public_key_hash and odm_production_mode).
I was wondering if my flash failure could be related to the burnt fuses?
Is it possible to reflash a module with firmware that is not signed? in this case I understand that the start cannot be done, but is the reflash possible?
In my case, is it possible that the access to the EEPROM board information is corrupted? EEPROM HS or other?
Thank you for your response.
