    So, I managed to reformat my internal storage on my phone (to FAT) and now I can't boot the phone. It just bootloops.
    If i boot into recovery and try to wipe i get the error
    E: Can't mount /dev/block/mmcblk0p1
    (File Exists)
    Error mounting /data/!

    Now, i tried to reformat data from adb shell by doing:
    adb shell
    su
    format /data

    but SU is coming up as an unrecognized command... format also

    anyone know what I should do or should i chuck this out the window :)

    some info that may (or may not) help:
    rooted + s-off
    cyanogen 6.0.2
    kings kernel #2

    just google it. theres tons of instances of this happening. its a bit of a long process to fix, but definitely not irreversible

    So did you mainly just follow the steps in post #7 of that thread? Any other tips you can share? I would like to compile all available documentation for this problem because I have not found tons of info on it. I ended up at the same thread as you when I was searching.

    Anything at all you can add would be helpful. Thanks.

    Yeah i followed post #7. Once I did that the errors went away, however, I still could not boot properly even after a fresh wipe + install. I switched to a different ROM and then was able to boot. After that I was able to switch back to CM6.0.2 with no problems and my phone is back to normal.

    And if you wouldn't mind telling us how you ran into your problem in the first place so that we could potentially avoid it, that would also be appreciated.

    I can probably answer that. When you connect to the PC in disk drive mode, both the internal memory and the SD card show up as drives. Most of us have formatted our SD cards to FAT32 due to file recognition issues on the FAT format. If you inadvertantly select the internal drive instead of the SD card when formatting, you end up with this problem.

    Quite possibly the case. Glad I did not make this mistake.

    ^this... for whatever reason cyanogen 6.0.2 brings up the "oh no! you need to format this device to use it!" dialog when you mount the phone's internal drive to your PC.. so i, in my infinite wisdom, said "hey, let's do that so i can use the internal storage! for science!!" and then formatted it and made my phone very angry.

    Sorry you had to deal with that dymmeh, glad you got it worked out. And thanks for the recap on how it all happened. I'll make sure not to follow in those footsteps.
