I'd like to test my solution I need backup from your HTC partition (mmcblk0p7).
If my solution works you will get a sim unlock code for free. Only the first 5 backup playing!
pls don't ask anything about my solution it's just an idea. At the moment I don't want to sell or share.
Instructions(this will copy your partiton into the sd card):
adb shell su dd if=/dev/block/mmcblk0p7 of=/sdcard/htc.bin
Upload the htc.bin to somewhere. Mediafire, mega, dropbox...etc and share the link pls
