Ā 

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.

How do I get that help also?? I'm in desperate need of help

I downloaded the .rar file, Ā decompressed it and copied the files to a 8 GB USB stick. Ā I had previously wiped the stick and reformatted it. Ā I'm using a Mac. Ā I formatted the USB stick first time as MS-DOS, tried it, nada. Ā Went back and reformatted the stick as ex-FAT, put the files back on it, checked to make sure they copied over. Ā Deck still did not recognize the stick. Ā Now in my case, the deck (NEX 4201) was installed with a USB dongle out to the glove box from port 1. Ā I have used this connection before to update firmware, and it works fine. Ā However, in this case, the deck did not see the USB stick, or to be precise, the deck did not go into 'factory service mode.' Ā Ā I've rooted other Android devices so the process is not completely foreign to me. Ā Any suggestions?

I found this in another thread. Hope it helps.Ā 
Ā 

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