I have a Pioneer F900BT. I put the 2 folders in the testmode.zip in the root of an SD card, I could boot in WinCE mode, I backupped the flash unit to the SD card, I turned off the ignition, I removed the SD card, and now, when I turn on the ignition, the F900BT doesn't turn on. What's happened? Did I brick the F900BT? I tried to reset the unit, unsuccessfully. Please help me!!!
