Bricked o2 joggler 修复o2 Joggler的启动失败问题

Try the blind typing thing with a bootable USB stick.  

If you get it to boot then reformat the MMC a couple of times and rewrite the EFI boot partition to see if you can get it to boot from a USB stick.

Only try the boot from a directly plugged in USB stick either inside or on the side and no USB hub.  Plug the USB keyboard / mouse combo into the second USB port (remove the USB wireless card for the time being).

Blind typing procedure:

Recovering an unbootable Joggler


1 - Before you do any of this, it is essential that you have a working usbstick with an efi partition and a working OS with all drivers.

2 - If something you do leaves the Joggler in a non-booting state (i.e. stuck on O2/OpenPeak screen) take the following steps:
A - Don't Panic
B - Attach keyboard and known good usb stick, and apply power to the Joggler
C - Press escape frantically (oh yes just like the good ol' days)
D - Once the num-lock key has lit, press escape a few more times. The process has worked if the numlock/caps lock key switches on and off when you press the appropriate key.
E - type the following: fs1:boot and press enter. You are typing blind thanks to the jogglers boot screen.
F - If it doesn't boot the USB stick repeat the whole process.
G - It it doesn't work repeat the whole process but type fs0:boot and press enter

3 - Once booting into Ubuntu delete the MMC parition, create one EFI boot partition (DD or just copy it with GParted).  

4 - Test the booting to USB with the newly written EFI boot partition.
