I was in the process of updating the firmware with the micro SD when my friend hits the Star on call button that interrupted the power. The screen just flashes from very dark grey to black. I turned off the truck and waited 30 minutes to see if it would reset. Nothing. I called Pioneer and they said I might have locked up the memory and would need to send it to repair. Before I go back to the dealer is there anything else I can do to try to fix this? First post here. Just looking for help. Thanks!

Can you boot to testmode (i.e., testmode.key file on sd card - search for testmode.key on this forum)?

If you cant boot to testmode:

pull the battery fuse to the radio and/or power harness on the avic and wait for at least 20 mins.

Then power everything back up and see if you can boot to testmode now.

If not, you are bricked. If this was a legitimate (purchased) update, or if it was a legit minor update (downloaded from pioneer website) and all instructions were followed, or if it is still under warranty, you might be in luck. If not, it will be expensive to repair. I think pioneer charges about 200 for a refurb.

Somebody else mentioned that one of the various "repair shops" available by ebay can fix this particular problem. I doubted it, but they messaged one of the sellers, who claimed they can fix this. So if you can verify with the repair shop that they cover this particular failure (be sure to mention that you lost power while the unit was updating and exactly how it behaves now) - then you can probably get it fixed for less than 150.

Good luck.

I am having a hard time downloading the correct testmode files. I tried to download Condi Hack's zip file for 1.4 Base install and when it unzips is asking for a password. On top it states use Av.exe for password, but it will not accept it. Am I using the correct files? I also tried these below with no luck. I really appreciate your help!!

Why are you messing with Hackmode? Follow pionara's instructions. Use Testmode. Hackmode modifies files on the AVIC. So it is dangerous and can make matters worse. Get testmode.key on an SD and insert it into the HU. If is starts up the maintenance screen, you aren't totally bricked. Oherwise, as pionara said - time for a repair shop.

I believe all the passwords are avic411.

Are these the correct files for test mode?

What you want is one file. Get it here: http://avic411.com/i...ode#entry256194 You'll have to unzip it first.

Testmode is a build-in service mode menu. There's nothing to install, just boot into it by having the file TestMode,key in the root of your SD, If you can't boot into TestMode, you're SOL. Then you'll need to send in your unit.

Great I really appreciate all you guys help! I have a MAC at home and when I download the zip file it tries to open in Keynote and keep getting format invalid. What program should this file be in? Sorry for all the knob questions.

there is one file called "testmode.key" that you put on the SD card, and then boot up the unit with this installed. If it goes into testmode your unit is salvageable. If it doesnt seem to respond or do anything at all, your unit is bricked.

Just google mac zip - you'll see several alternatives. Ive heard good things about WinZip for Mac. If you still can't unzip, try downloading the file again. Funny, its a small file - not sure why it's compressed anyway.
