    Just posted the output in my last post.
    Where to look for the HW revision?

    Turned off the device. Found the label under the battery.
    As for the 4-digit code, I only see a big 0434 between CE and the ! in circle. Is this what you want to see?

    PS I can't boot the device without the charger as the device doesn't wake up on battery alone.
    My microsd is a SanDisk 4GB Class2. I made three fat partitions, the 3rd being fat16 with boot flag all done by fdisk on another linux box.

    It is better that the device is not plugged.
    If I use another partition, can you please provide the manual commands?

    Thanks to another member's tip I got the backlight back (hit some key when uboot loads, enter 'reset'). Now I see the whole output and the correction is in this post.

    I am also curious about this because I see "mmcboot" in the short list of commands upon booting in uboot.
    Issuing mmcboot gives this:
    Code:
    Booting from mmc ...
    Wrong Image Format for bootm command
    ERROR: can't get kernel image!
    So would it be possible for someone to create a bootable image so that we can boot off SD and then find ways to repair the system?

    1 - Expand attached archived on SD (must be on third Fat partition)
    2 - Start N900 and enter on u-boot interactive console (by booting with open keyboard and pressing any key).
    3 - Type mmc init and press enter
    4 - Type run loadbootscript and press enter
    5 - Type run bootscript and press enter

    This should run maemo with stock PR1.3 kernel (included in the zip file).

    After booting I suggest downgrading to power43 kernel with the command (as root):

    apt-get install kernel-power=2.6.28-maemo43 kernel-power-modules=2.6.28-maemo43 kernel-power-flasher=2.6.28-maemo43

    And I request that people will tell me about having this problem, including the HW revision of their device.

    Saying it "doesnt work" doesn't help. Posting any error messages, any observations is of more help.

    ...
    so uboot loads no matter how.
    battery out -> start flasher -> plug usb -> battery in?
