man i suggest to u to learn ASM for micro controller..
i only looked at reversing nokia firmware, and this is based on ARM architecture (very similar to ASM for PICmicro)..
if u want to make programs with the knowledge u gain from reversing the firmware (like flash patcher or unlock by cable for example), i suggest to u go learn C++ or maybe even visual basic..
i also learned ASM for windows, but this is not such a good language to use everyday..
i only learned that cos i was interested to reverse win32 applications..
there are many good forums for help with all these languages and also reversing/cryptography..
best site to use as ur homepage; http://www.google.com :) |
