Been poking around this some more, there seems to be a 2048 byte header on boot and recovery, its got a signature of 'FA CE BA BE 28' followed by an offset that (kinda) points to the signature.
the signature is at the end of the image, right after the ramdisk, according to the spec, it is where the Second Stage bootloader would be, and consists of 512 bytes of what looks like Junk...
I've changed the offset which seems to make no difference (the stock recovery still boots), but removing the signature seems to cause it not to boot.
The fortunate part is that since they 'accidentally' included a hacked version of Clockwork Mod you can easly root the device, and make some changes.. but its going put an end to things like over-clocking and custom recovery
I have this device and i have problem with the boot.img and custom rom. I use HTC Android Kitchen 0.198 for my custom rom when extract boot.img stock the kitchen not find magic header and later find with 2048. I have changed only default.prop for use adb on in the ramdisk and repack all but the new boot.img go the device in bootloop.
Sotck boot.img is 5,2 mb
My new boot.img is 3.1 mb
My ask is ---> this device have bootloader lock
? -----> Is ok only Boot.img of stock rom
When i unpack and repack boot.img the new rom go in bootloop. For unpack and reapck boot.img i have used the HTC Android Kitchen 0.198/0.197 ⃕and also manually with unpack-bootimg.pl/repack-boot.img.pl and mkbootimg but always bootloop........ (# chop off the header$bootimg = substr($bootimg,2048
) ---> for unpack. I tried also with 4096.
Same mb of HTC Android kitchen 3.1 mb
Alcatel Recovery 184.108.40.206 have problem with usb mount
I also cocked my custom rom but have problem with the process com.android.phone
