I think I didn't pay attention to the original fuse and lock config for 162.Īnyway, there is anyone who can help me with some information so I could make it work after the upgrade or revert to the original setup?īFirst of all, it is impossible to "back up" the firmware and EEPROM content in the conditions you have. Now I tried to revert it back to the original version (1.84) but I'm getting the same message from VCDS 19.6 - port ok, interface missing (before fw upgrade used to detect it properly). In any case, before programming I saved the old flash and eeprom. Some other information say I should remove the chip completely. The cable has an STC 12C2052 chip - I found information saying to cut pin 9 before usbasp programming and I did that. VCSD 19.6 says the port is fine but the interface is missing. I found some information describing how to detect the hardware version and successfully applied version 1.96 for flash and eeprom. I have an older VAG11.11 cable for which I attempted to upgrade the firmware and the eeprom using USBASP.
