Hi all,
I have a problem with the radio F920BT, during the update 5.00 in TESTMODE created a problem, because I deleted the folder PRG0 and do not know what to do. Radio launched again after turning the ignition switch and displays only the Welcome board and is so for a minute or maybe two (which is better in this mode works reversing camera but nothing else) and suddenly the radio resets after 2 minutes and chapel, dark screen and just shine buttons. Radio does not respond to the card insertion TESTMODE just like radio did not see nothing on the SD card. The tragedy needs help. Maybe someone fought with something like that? Please help ....

Does anyone know a service in Poland that would fix it?

Just restore your backup.  You did take a backup... did you?

If not, is there a PRG1 folder?  it might have the files you need.

I current do not have a backup, but it wrzuciłbym because I have some old year. Just like how I do not know how to get on to read from the SD card to enter into a service mode.

Or is it some combination of keys? I remember that at some forum or somewhere on the internet I found once some key combinations of inclusion and passed this test mode.

You need to have a PRG0 folder inside your USER folder.  If you don't, your unit will not work.

I have never heard of a key combination to skip something on the unit.

Well, just how to copy files to PRG0? Maybe the CD is there a way? Or if I disconnect the battery for a long time and then react to the radio and call boot from SD?

To enter Service Mode: Let the device finish starting. Press and hold "Home" then press right,left,right,left,right,left then release "Home"

Maybe someone has an idea how to flash the radio? There must be some way without interference inside.

there is no person who can help?

If there is a FLG file directly within the USER folder the PRG1 file should start up the device.

Otherwise do copy the PRG1 folder rename it and past it within the USER folder.

The device should start up.

OK, But how to get to memory and create a folder PRG1? If you can somehow get to the radio from the USB or some way through the microSD card as there is no PRG directory?

Can someone toss to download the file PRG.FLG and PRG1.FLG?
