The instructions have been given previously in this thread, follow the same procedure and you should probably be good.

You can do it by entering test mode and copying and/or deleting the user profile. Grad the test file from here: http://avic411.com/index.php?/topic/81469-avic-development-mod-device-backup/%C2%A0for%C2%A0this. copyit to a usb stick, insert to your pioneer HU and start the device. Choose file maintenance and enter the extdata partition look up user and there you have it.

I missed your response but yes that was what I was talking about. Either way sorry if I hurt your feelings not my intention. The situation is kinda resolved, I can access the system but every time power cuts it asks for password which is very annoying.

I remember that I had issues with the extdata partition, if I am not wrong the folder with the user data is empty on my unit on the extdata partition. Resetting from testmode didn't do anything to remove the password. I have lost my usb drive and am not able to enter the testmode at the moment but will get a new one pretty soon, I will post here any updates on unlocking the unit. Thanks you for your help I will join the groupchat!

Couldn't find the database files containing the passwords and resetting settings to defaults did not help. I am starting to think that the headunit has more faults than just the password. Thanks anyway for the help!

Seriously RonS, I don't understand why you choose to pick on me. The user before me got a PM that helped him solve the problem. He did not share any information on how it was fixed for him and you didn't jump on him. Chill out a bit, I got the same help that he got and provided about as much information back to the community. I would love to contribute more to the board but my knowledge and skill in programming is quite limited.

No it would not have killed me. Whats up with the aggression? I did not go in to details since it seems to be kept a secret how to remove the password. The user that helped me got his gratitude in a private message.

Issue got resolved!

Hey guys, I would need the specifics on how to recover the password. I have been trying to use the guide provided here: http://avic411.com/index.php?/topic/81468-the-avic-development-mod butI dont seem to succeed if anybody could help me out with the steps it would be great. I have a AVIC-4100NEX that I would need to unblock. Eternally grateful for any help!
