Please help: I think I have bricked my head unit
Ok, stupid stupid stupid, but I have been trying to reflash Windows CE on my Chinese 2-DIN gps head unit, since a couple of folks have succeeded in changing the language from Chinese to English, being able to actually store all settings made, etc.
I have followed the instructions here (post from zygo10)and have downloaded "updated firmware with wince5 in english".
So I had the files on a SD card, pointed the head unit to the executable and the Windows CE Sysupdate tool came up. I pressed the FLASH button, it started flashing, told me it had been completed succesfully and the instructions then said I had to power off and on again.
And all I got after powering on again is a white screen. That's it. No reaction on pressing the screen or any of buttons/steering wheel control, other than the white (and backlighted screen) it is completely dead.
Resetting it using the reset hole does turn it off, but the white screen's still there when powering on again.
Inserting the SD with that update again doesn't do anything, both when the unit is on or when I power it on with the SD card inserted.
I have also tried the files called "original firmware with wince5 in chinese", but without result.
Ok, again, stupid stupid stupid, I should have known better, but is there a genius here that knows how I can possibly fix this bricky mess?
I will be forever thankful.
