I bought a used vehicle this week, problem is power was lost to the battery over the winter and it now has a password lock screen on the unit.

Pioneer wants $80 password reset fee plus I have to pay to ship it and return it.  anyone know a master reset password?

As far as I know there isn’t one. Since the previous owner changed the password you don’t have a choice.

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