Reverse engineering a feature phone firmware
Reverse engineering a feature phone firmware
(29-12-2019, 03:57 AM)Koken2003 Hi. I have a feature phone it5081 and it is a spd chip based device. I want to make some modifications in its firmware so i downloaded its binary firmware which was available on internet. I came to know about some programs like binwalk, firmware mod kit etc used for reverse engineering. But, all the guidelines and discussions available on internet is all about binary firmware of routers, smart tvs, android phones etc. So, is it possible to extract a feature phone binary firmware somehow?

I personally myself think that it is possible to modify feature phone firmware.
Most of feature phones based on ARM 9 or ARM Cortex platform, we have to find base address for IDA Pro to reverse engineer it.If you did all still there are CRC32 Checksome which prevent to modify firmware.
We have to disable it.
I also need someone to teamwork for it, if you have time or you did read this message @Koken2003 then contact me.

hey, it's been long and good to know you're still here
maybe you could try reaching out to the OP via email if he's still interested
