You MUST use the dd command after booting from diags, to successfully write a main partition image. If you write main while booted from main, it often does not work correctly because the main partition sometimes writes to its filesystem. Writing to a filesystem and to its raw partition at the same time will damage it to some extent (perhaps too much to repair).You need to reset the boot counter stored in the /var/local partition, or erase the /var/local partition that contains it (mmcblk0p3). You can reset the boot counter with this command at an SSH prompt:

echo 0 > /var/local/upstart/lab126_gui.restarts

There are scripts posted that can do that for you. You can also erase the boot counter file instead of resetting it to zero.

thanks lot

i will try
