Firstly my Kindle isn't bricked and completely works, it has just had a screensaver hack done to it.

I was wondering if I can copy over the file mmcblk0p1.img (from K4NT 4.0.1 forensic images) to my Kindle in Windows using a normal USB transfer, and then run the following commands in Putty when in Diags mode.

(From Silver18 noobs guide)

dd if=/mnt/us/mmcblk0p1.img of=/dev/mmcblk0p1 bs=4K

followed by

rm /mnt/us/ENABLE_DIAGS
idme -d --bootmode main
reboot

Would that do it? Or are other steps needed?

Thanks
If your Kindle was (is) running the 4.0.1 kernel now, then just re-installing the image as noted above should do it.
Otherwise, you also need to re-install a matching (main-k4-4.0.1 or whatever the matching name is) kernel also.

The reason:
These kernels use drivers and features as loadable modules, the kernel is in the kernel image but the kernel modules are in the file system image.

Grumble: It didn't have to be that way, but it was the way lab126 choose to do it.
