Ok, that wasn't to painful. I deleted that file. After I rebooted, I got a message saying that no applicable program is available and the unit won't do anything after that. The only thing I can do is use the SD card to go back into testmode.

Sounds like you deleted more than just one file. There's no way deleting just PRG.FLG would cause that. If it did, the file is easily replaced. It is just an empty file indicating which of the two latest software versions to load.

Path: USER

 

..                                         .DAT

 

 

PRG                                    .FLG                                AR

 

This is roughly how the menu looked and the letters highlighted in red was the only thing I deleted. What software do I use to recreate this file?

I hope there are also directories named PRG0 and PRG1. If not - game over. That "no applicable program" error means the unit can't find NAVI.EXE which is in both PRG0 and PRG1. The one it tries to load depends on whether PRG.FLG exists. If it is not there, it runs the files in PRG0, otherwise PRG1.

 

To create the file - on your PC open a text editor like Notepad and immediately save as PRG.FLG.

No, the other files are still there. My daughter was playing on my phone so I couldn't take a picture at the time and I was just trying to show you the only file I deleted. Do I put anything inside this notepad file or do I just leave it blank and name the file prg.flg all caps?

It can be an empty file. Doesn't really matter since the presence/absence of the file is all that matters. The case of the file name doesn't matter since windows is case insensitive.

 

Oh, another cause of that "no applicable program" error is installing Condi's Hackmode. Has that ever been installed on this unit?

No it hasn't. I knew better than to do that. Ok, so my SD card should look like this?

TESTMODE.KEY
PRG.FLG

Then I just copy this text document file from the sd card and paste it to the path I deleted it from correct?

Yes, but it is a pain to do because TestMode is so un-friendly. I just remembered, I wrote a script that will do this. Just download and copy the included 3 files to SD, and insert.

Cool thank, I'll try it out. Quick question though. How do I get out of testmode once I'm done making these changes? I'm wondering if the very first time I went into testmode if I did something wrong. It says press the navigate button or what I'm guessing is home on my unit to exit. This allowed me to get out of the file extension I was looking in back to the main testmode menu. So I just took my SD card out and turned my car of. Is there a reboot sequence I can use? I'm pretty sure I shouldn't have done that, but I figured everything would be fine since that's what I did after installing the short fuse hack and updating the maps.

To get out of testmode I just eject the SD then turn off the ignition. I've never found a way of gracefully exiting.

Well, I ran the script and the unit is once again operational for the most part. But I'm still getting the tuner restart error. Do you know if there's a way to remove the display of error messages somewhere in test mode? Because the unit is working fine, it's just that the error message blocks your view and prevents you from using the menus without hitting the ok button constantly.

in your script, replace reboot with RESET 1

Wish I could:
- display my phone display on the z120bt (BTVideo)!
- install Android on the z120bt and use BTDUN to browse the web!
