Assorted Q&A:
Document it yourself. Just log on and do it.
Here's an example of creating a yaffs image from a mtd device:
# mkdir /cust
# mount -t yaffs2 /dev/block/mtdblock22 /cust
# mkyaffs2image-arm-uclibc /cust /sdcard/cust.img
# cd /path/to/destination
# unyaffs-arm-uclibc /path/to/yaffsfile.img
As suggested by nadlabak, we can simulate the event that corresponds to the slide keyboard being opened, which has the side effect of rotating the display.
# simulate keyboard slide out sendevent /dev/input/event4 5 0 0 # simulate keyboard slide in sendevent /dev/input/event4 5 0 1
