[HD2 Android Q&A, Help & Troubleshooting and Genera] HypoTurtle:
I suppose so. I believe it's a simple enough dd command. Let me fire up linux and see what I can do. Not sure why it seg faulted (I think I took the unpackbootimg from the initrd_patcherv2.zip). Couldn't get my head around it atm. Lets try a different binary first.

Add the attached to the /sdcard/bins folder and run the script:
