Hello all once again!

I am still working on my X920BT that was bricked during a firmware update sent to me by Pioneer. Since then I have managed to get it to respond to a number of attempts, bricked it numerous times and recovered it to a point where I can reliably get it into test mode without it shutting down on its own in the middle of making changes. I can also get it to recognize programs such as Condi's Hack Mode, Super Test Mode and that's about it.

During startup it will go to splash screen and then go black with the words Program Startup Error. It will allow me to put it in test mode and from there I have full access to all files. I have done a number of things to attempt recovering the unit to a point where I can use it once again but no luck. My ultimate desire would be to update the unit to something above 2.0.

I believe I need to find a way to rewrite all the files on the unit to start fresh. I am not sure if this is even possible so suggestions are welcome. If I have already tried a suggestion, I will let it be known. I warn though, I have tried so many different options that its getting discouraging. It acts like the Cardinfo file is not working as not one single update has worked. It also will not start an upload on its own and requires me to go into test mode to physically copy and paste each file. As mentioned, the only files that seem to work on their own and without me doing anything are the couple in the first paragraph.

You help is greatly appreciated!

Some people have succeeded by disconnecting the unit from the main power (ie. disconnect car battery) for about 30 minutes.  Apparently this somehow reset the unit.  Have you tried that?

I don't know what's the file structure on the SD card provided by Pioneer, but I believe it should be a simple copy.  Instead of using the Pioneer updater, are you able to manually copy the files and then set the PRG.FLG file?

Thank you for responding!

The unit is out of the vehicle and set up on my test bench. Power has been off for far more than 30min. Its defiantly not a power thing that's going to fix this unit...... The unit was in my truck when I received the SD card from Pioneer with the update on it. I followed the instructions on the sheet provided by them with the update and did so exactly as they tell you to. Shortly after I installed the SD card from Pioneer into my unit, it became bricked. I had white and black lines running horizontally across the screen. I then cycled power just to have it end up looking like "snow" on the screen with no touch screen functions or anyway to get it into test mode. This was when I removed it from my truck and moved over to my test bench. I messed with it for days and days until finally I started getting a splash screen about 1/10th of the time I did a reboot. Finally when I had a splash screen I ran across this forum. I followed all information I could find with zero luck beyond getting into test mode. Although I did get an opportunity to backup the unit, it was clearly corrupt and in my opinion, it probably rendered the backup files useless. I figured it would be pointless to revert back to a bricked unit!!!......... 

Maybe if I knew exactly what files I should copy I could go ahead and try the manual copy and paste method. I just do not know exactly what files to replace and until I can get some help in that area, I have been sitting back and reading as much as possible. It seems to me that there should be a way to get a copy of another persons X920BT files and replace my current files with theirs. I hate this and the fact that I have such an expensive unit currently no better than a paperweight.............

Like I said, if there is anybody who can tell me the exact files I need to copy, remove and change, I will do so right away. I am sure I have all the needed files in the latest update I have available to me. I just need some guidance on which ones to replace because my unit will not do the auto replace feature as it should........ Probably due to a missing file or a incorrect file in the unit.

Thank you!

Perhaps you can try installing the 2012 update.  It has the USER folder that might save your butt.

Get the update here: http://thepiratebay.sx/torrent/7672652/Pioneer_2012_US-CAN_Map_Upgrade

Installation instructions here: http://avic411.com/index.php?/topic/35230-2012-uscan-maps-cnsd-310fmuc-upgrade-updated-to-supereasymethod-beta/

Is there not a way to do a complete rewrite of all folders? I think there are files/folders that have been deleted on accident during this process of recovering my unit.......

I cant seem to figure out this torrent....... The only file I get is for some stupid video program. Its 6528kb. Not the 7 files that are over 2GB as expected. This is exactly the type of mess I have been dealing with since I started this process months ago....... Can anybody help me out please?

I just downloaded the torrent and it's offering me the expected files, including the 2.23gb one.  In other words, the torrent is perfectly fine.

OK, I was not doing it right....... Sorry.

So now the issue is that because my unit will not go to a usable screen and defaults to Program Startup Error, the only way for me to get into anything usable is to manually put it into test mode. It will not auto load from the SD card upon startup of the unit. Does this make sense? 

Suggestions?

Thank you for your help!

I'm no expert in this, but there is a "BOOT" folder in the "USER" folder (/USER/PRG0/BOOT).  I guess that the unit is looking for files inside this folder to start (I only have EU090BOT.PRG in there).  Do you at least have this folder?  If not, putting files in there would be a start.  If the unit knows how to boot, I guess it should know how to read the SD card.

Here's a DropBox link to my EU0990BOT.PRG file: https://dl.dropboxusercontent.com/u/108951927/EU090BOT.PRG

Well I wish I could say it wasn't there but it is..... That's a good start! I thought I read somewhere that it was Cardinfo file that was the one which did the card reading. I wish I knew. I followed the directions given to the T. I can get it to read and accept the RenewalIFLib-Auto-Replacer file but when I go to put in the 2012 Upgrade file it does nothing. Its got to be something easy or this thing would not be working at all.

Thank you for giving me a hand. Hopefully this will get resolved soon!

Cheers!
