You have to read the EEPROM in order to perform immo off, not the flash.

Immo off in flash is possible

I've seen this mentioned at least 3 times on here by different people. Anyone going to shed some light on how it's done?

I already did. There is no magic "change this byte here" solution, you need to disassemble.

I'd imagine you change the function that reads the eeprom bytes for immo to always take the immo off route, regardless of what is actually in the eeprom.

finding that in the disassembly is the hard part, though...

Should be pretty straight forward to look what is the immo values addresses to eeprom, then find out what is eeprom starting address at the memory map and used DPP page. From these calculate the whole address by which can search the disassembly and find where it is used at the code.

Anyone able to give it a shot?

Just got a new cluster from wreckers and need a easy fix if possible

read the eeprom from the orig and write to the new one
