Useful article on patching Nokia DCT4+ firmware

Hi folks, Came across this article in the latest PoC||GTFO journal describing (part of) the process for patching firmware on Nokia DCT4+ phones. The good stuff is pages 22-29 of this file: http://openwall.info/wiki/_media/people/solar/pocorgtfo03.pdf Alas, this does not appear to permit patching the first 1MB of firmware, so may not be helpful for OsmocomBB. But perhaps someone with more time on their hands can take this and run with it... Cheers, -Andrew
