Thank you dear Pepi for instructions. 

I read the EZS and realize that the eeprom contains the correct information. 

   

Then i found the same EZS box with the same references and the same PCB, i write the eeprom dump from the old to the new, is ok but it will not write the flash, error towards the address 0x1B7BF. 

When the original and donor flash are compared i can see in the original flash "FFFFF..." and in the donor "A7A7A7..." i would share the 2 flashes to be clearer. 

I tried the donor EZS with the eeprom from the original the key does not turn Of course i also tried to connect the donor EZS with the SQU emulator ELV module (julie) but the donor key does not work, I think the module does not work well. 

I'm sharing the screenshots to ask for your help please. 

Thanks.
