oh ha this new unihertz titan is based on a mediatek chipset line that
   has been thoroughly exploited in multiple ways to bypass its security.
   the exploits appear to be open source. they are made by human beings
   who can be talked with.
   mediatek chips are apparently arm. the author of mtkclient has an
   exploitation playground repository
   at [1]https://github.com/bkerler/exploit_me . i'm not sure what it is,
   but maybe a vulnerable binary so that people can learn how to build
   exploits to phones by reading their firmware? I'm actually not sure.
   the most prominent exploit for these devices is called kamakiri, the
   source code for which is
   at [2]https://github.com/amonet-kamakiri/kamakiri . I don't know
   whether it's relevent for my phone or not.
   bkerler's mediatek client at [3]https://github.com/bkerler/mtkclient
   has a number of additional command codes in it, many copied from the
   work of preceding developers, showing how to do useful things like
   reading and writing ram and emmc without the download agent (I think,
   not certain). this developer also has a qualcomm client they have made.
   i'd like to try to figure out what kamakiri does, and basically if any
   of these exploits are relevent for my phone. ideally i'd like to learn
   what is necessary or if it is possible to lock down my phone to prevent
   mutation of it or of firmware dumps I download from it.
