I've been doing similar hacks for ~25 years. I mainly repair arcade games but my house alarm had an installer password on it so the user can't change any settings. I dumped the eeprom then using the installation manual I found online I did a factory reset. then I dumped the eeprom again and did a search within that dump for the known factory password. then I simply looked at my original dump at the same memory location and found the installer's password. now I can change any settings I want LOL! You sound like an Aussie... me too! I'm on the West side Perth. Where are you?
@@howiesauto so how did you know which exact byte to change? The actual security code could have been discovered by doing what i did by dumping and finding a known code in another radio and checking the same location in the unknown radio, but what you did seemed to be to disable it... although you didn't actually show it working and code disabled afterwards.
some are easy and some are hard,depends on the code type and if you have two radios the same you can use a program to compare the two dump/eeprom files@@g4z-kb7ct
some can be read on the board but due to other components like resisters ,capacitors they have to be removed,i will always try to read the chips on the board first before removing

Can this eeprom not be read/written without de-soldering using a SIOC clip reader
