Patch

A patch for start.elf, a firmwware blob for the VideoCore IV processor used byall Raspberry Pi models, was posted toredditby /u/fuck_the_mpeg_laon 03-03-2017:

Applying it to a4.14.44 start.elf(latest as of time of writing) results in the following diff: Adobe photoshop cs6 key generator mac.

Some initial analysis was done by q3kon Hacker News:

Yes, it seems to patch a licensing function at 0xEC95FD4 [1] to always return 1,by patching the jump at 0xEC95FE2 (that should be only taken for the always-allowed H263 codec)to always be taken, thus always allowing all codecs.

Reverse-engineering

The initial entry point is disassembled using theVideoCore IV pluginfor IDA Pro 6 by hermanhermitage.

After loading and analyzing start.elf, we can find the is_licensed routineat address 0xEC96290 by jumping to the file offset given to us by xxdbeforehand. The relevant code sections are available insub_EC96290.asm and is_licensed.asm.

Here, two memory locations (0xEE86680 for MPEG-2 and 0xEE869E0 for VC-1)that point to the .bss segment are checked to determine the return value ofis_licensed. There are no other obvious references to these locations instart.elf, so memory-breakpoint debugging (TBD) is probably needed.
