If the loader is signed, it checks the signature on itself. The bootloader (MBM) does not check any signature on the ramloader code, otherwise it would be (almost) impossible to run a kernel with boot_usb. And.. If the ramloader checks a signature on itself, it IS possible to patch it, as long as you patch the code that does the signature verification too. I will do some tests with a hacked ramloader on a1200 as soon as i have some time. -- Daniel Ribeiro
