This was the dev teams approach to unlocking Bootloader 4.6.

As noted during the CCC talk that the dev team gave, this exploit was actually never fixed in baseband 1.45.00, only in the next rev, so they were able to use it as an injection vector for some of the earlier hacks that they did on it (downgrading the baseband version to 1.43.00, backing up their seczone, etc.)

Exploit

This relied on a buffer overflow in the STK.

Leaked Source

Note

Zibri removed it from the Google Code page, but the source is still easily available via google cache, or the fact that Google Code wiki pages are svn based and you can easily just look at an earlier rev :)

On the page before the source got deleted, Zibri referred to it as C source, although by the looks of it he may have failed to realize that it is a payload meant to be run off of a TurboSIM
