We were using u-boot, kernel and rootfs images from http://people.openmoko.org/werner/devirginate-20070301.tar.gz to pre-install the devices. This is a self-contained devirginator snapshot, and can be used at any given time to fully restore the phone (complete loss of data is implied). This is how to restore the phone:

  • Go to a convenient directory, then
tar xfz devirginate-20070301.tar.gz
  • Enter the directory:
cd devirginate-20070301
  • Disconnect everything:
    • the USB connector of the debug v2 board from the PC
    • the USB cable from the Neo
    • remove the battery
  • Connect the Neo to the debug v2 board.
  • Connect USB of the debug v2 board to the PC.
  • If you have a serial console, start it now. The device should be something like /dev/ttyUSB0.
  • Connect the USB cable of the Neo.
  • Insert the battery.
  • Power on the Neo. (If it has powered on by itself, that's okay.)
  • Start OpenOCD (if you have a local openocd.cfg, please use that one):
tmp/openocd -f tmp/openocd-debugv2.cfg
  • OpenOCD should print one line (below) and keep running:
Info:    openocd.c:84 main(): Open On-Chip Debugger (2007-01-31 12:00 CET)

If OpenOCD prints an error, please disconnect the USB cable of debug v2 from the PC, connect it again, then restart OpenOCD.

  • In another window, start the install script:
./devirginate -0 -1 -2
NOTE: The -0 option irrecoverably destroys bad block information provided by the chip manufacturer. This is only appropriate for devices from phase 0, or earlier. Instructions will be updated for later models.


Watch the screen of the Neo. The following things should happen:

  • it turns on, showing weird things for about 10-30 seconds
  • the screen goes dark for 1-2 minutes
  • the screen lights up and shows a smiling face for a few minutes
  • the screen goes dark and shows a partial (broken) OpenMoko logo for about 5-10 seconds
  • the screen goes dark again, then shows the full OpenMoko logo
  • the machine will boot Linux now and start touch screen calibration

Errata

  • u-boot can power-off the phone while in DFU mode
