Possible idea: just reboot with different random values until it works. April fools issue or not, the whole thing really is madness. Hardware blocks that decide not to work without a key. The point of buying the license keys is to enable hardware decoding of MPEG-2 and VC-1 — see Why does the Raspberry Pi need a MPEG-2 licence? For more information on why you might want this. While there was much rejoice recently at the patents expiring for MPEG-2, this makes little difference to Pi users, it seems.

This is an effort to reverse-engineer the Raspberry Pi license key check forMPEG-2 and VC-1 hardware video encoding.

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:

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.

How Do I add an VC-1 license key to my Raspberry PI?

Before purchasing your License from the raspberry pi shop you will need your Pi’s serial number. This is quite simple to do.

Windows 7 ultimate crack key generator. Get Your Raspberry PI Serial Number

  • Boot UP your PI.
  • Goto system > system info > network.
  • Note your serial number – should be something like 000000000ffae29e.

Once you have your Serial number go to http://www.raspberrypi.com/vc-1-license-key/ fill in the form and pay your money. 2-3 days later you will get an email with your new License code.

How Do I add an VC-1 license key to my Raspberry PI?

In the email you will find a line similar to decode_WVC1=0x7654321 the “0x7654321” is your License.

Add your License to your OpenElec / XMBC Installation

  • Insert your SD card in to your PC or MAC etc.
  • Open up your SD card in your file viewer of choice.
  • Open config.txt.
  • Scroll down until you find # decode_WVC1=0x00000000.
  • Delete the #.
  • Change the 0x00000000 to your new license.
  • Click save.
  • POP the SD card back in your PI and reboot.

Note – Some versions of XMBC have a field in their settings tab to allow you to input your license directly via the interface.

That’s it your job is done.

If you use multiple OS versions on multiple SD cards you will need to add the License to each.

Test your License

This process uses SSH, i would suggest you use a program called putty get it from http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

Default SSH username and password on openelec is username = root and password = openelec

Get your IP address from system > system info > network

  • SSH into your Pi.
  • Type “vcgencmd codec_enabled WVC1” without quotes.

You will then get either a WVC1=enabled or WVC1=disabled.
