Looking for a good decompiler - any suggestions?

Hello all,

I'm looking for a good (free ) decompiler that is capable of decompiling Bitmain firmware - can anyone give me a suggestion?

Thanks.

Thanks.

Bitmain firmware is basically just an OS partition.
Nothing to do with decompiling.

Thanks kano, I realised my mistake while at work earlier.....

Can you recommend a suitable (cross platform?) decompiler for regular applications/binaries?

Why would you want a decompiler when you can just use the source code?

I'm looking for a good decompiler for software that doesn't provide source code.

There's only one that's even marginally good for compiled (non-interpreted languages), and that's Hex-Rays:

That being said, you can't recompile what you decompile, so it only will give you is slightly more insight into what they're doing...  You're better off just getting a disassembler and working in assembly - it will completely work, and you can do whatever you want, but it's also much more difficult.

Which software in particular? Its hard to help without knowing specifically what you are trying to decompile and why.

This is very true, reversing most compiled languages such as c and c++ is very difficult. The software on bitcoin miners is mostly written in c with scripts controlling execution and configuration.

Last time I looked at it HexRays was not ready for production use. With trained eyes, disassembler and debugger it's possible to locate algorithm inside a program and make usable C sketch of it, but it takes A LOT of time, think ~3 full days for 100 lines of C code.
