I came up with one idea. Without connecting the ground. Using Nor Flash Backup. To do a factory reset. Can you confirm if it can be done? Attached screenshot. Is this what Nor Flash Backup and its options look like?

Hello. Regarding the reset button, it does not restore the factory settings, it only resets the clock. As for the handbrake, this may be a solution, but while removing the radio, I may have accidentally disconnected the cable from the ground. For now, I will leave it as it is. What mattered most works. I do not want to disassemble half of the dashboard again to remove the radio. Again, thank you for this image and I encourage z9200dab owners to check your image because it works very well. Best regards

Thank you very much San4os for the image. A strange, magical thing. In my avh-z9200dab radio, I made a step forward thanks to your image because previously the 4500 only image did not start the FM radio. In your image I got the FM radio but did not start android auto and dabfm. The magical thing is that I cannot restore the factory settings because this option does not light up just like the update that I would like to try to start android auto. A strange thing. Such a small step as restoring the factory settings and unfortunately I cannot do it. Maybe you know what to do with it. I can report

can you tell which file you used for z9200dab? 4400nex or 4500nex? Regards
