Locked out of AVIC 4200NEX


Recommended Posts

Glad I found this forum, 

 

I like to hack around with stuff so I will probably end up doing more later... and posting results.

 

However my current predicament is as follows:

 

I had to clean off my battery terminals and forgot my password apparently. ( swear I have the right one) .  I've ran the perl script and created my testmode_a.key and have placed it on a fat32 formated usb, however... I can't get the faceplate to open up to be able to insert said usb...

 

any help is appreciated.  I don't want to have to remove the device from my truck.  Before you ask, I have tried the pin to the right of the eject button.  All it seems to do is cycle the device into post and boot, and then ask for the password again.

 

(NEX 4200)

 

I'm a systems and database administrator with production databases on RHEL 7 and HPUX so I think I can make my way around an andriod device ok with a little help from smart people about the pioneer.  I just need the damn faceplate open for my next step.

I'm in the same boat. My new 8200NEX(less than 2 weeks) will no longer eject(move motorized panel to the eject position). The disc and sd card icons are available but inop. The tilt icons are grayed out. I've tried unhooking the battery and doing a factory restore but nothing has worked. It does not even try to open...
