Public bug reported:

When asking abootimg to process a stock *signed* boot.img (named 
boot_signed.img) found on some HTC devices, perhaps also Motorola (not sure), 
the program reports:
"# ./abootimg -u files/boot.img -k newboot.img
files/boot.img: no Android Magic Value
files/boot.img: not a valid Android Boot Image."

HTC adds a 256 byte encryption/sign/key to the front of the boot_signed.img 
file loaded stock on their newer devices. Would it be possible to have this 
binary updated to be able to handle the boot_signed.img files? Essentially it 
would need to ignore the first 256 bytes.
Dsixda Kitchen is the only desktop product which seems to be able to currently 
handle these boot_signed.img files. Link to Dsixda's Android Kitchen -

Thank you!
