The most straight forward solution would be to create a very small image (less than a megabyte) of such an password-reset-SDcard that a windows-user without a lot of linux-experience can write to a SDcard and boot the pandora with. From there you can run 'password ' (replace with your actual username). The interesting bit is the part 'init=/bin/bash', which will put the system into a mode where a bash-shell is running with root-rights. Setenv bootargs 'ubi.mtd=4 ubi.mtd=3 root=ubi0:rootfs rootfstype=ubifs rw rootflags=bulk_read vram=6272K omapfb.vram=0:3000K mmc_core.removable=0 init=/bin/bash' ubi part boot & ubifsmount boot & ubifsload $ The trick is to boot that SD-card, that contains nothing but a 'autoboot.txt'-file that boots the nand, just like you would boot without SD-card with the exception of passing on an additional kernel-boot-parameter. But you WILL need an empty SDcard, that can be as small as you like (I just used a 32MB SDcard for testing) and on that you can set up a boot-able partition. It's a bit of an effort,yes, but there is no need to install the firmware to SD, if you want to change the password.
