it may be for newbies.Difficult process let me laugh… what is difficult here ? yeah I know find someone who have been able to do it …. I´m waiting return from people who have succes with it.
it is afterall intermediate process, but given the great documentation mena and the others, they did a pretty great job making it look easy. a bonus for everyone is that they are willing to share, lest trying to make it better and easy to follow.
the hardest thing about this is just lifting the b0 point, since the chance of breaking it is great, it's also a pain that the trace is under the chip, therefore we can't supply cut the line, everything else should be doable. (cracking security levels is another thing, and that's a whole new level of difficulty since it requires glitching the glitch chip/ ie reversing and making r/w available and unfck the chip
alternately it may be safer to just lift the chip and use a socket for the package. not exactly easier, but safer.
