Help/Support How to use lipo function to cut the binary file in gdb?

A binary file that consists of arm64, armv7 and binary, how to use lipo to make the file to arm64?

i've seen a post "Auto lipo arm64 & armv7 fat binary tool" but not understand it, seemslike the output is the deb file?

what need to install in cydia before can use lipo function? im using 5s ios 7.1.2

Grab the lipoARM64 file and place it in /usr/bin and set permissions to 755.

Then in Terminal type in:

lipoARM64 BinaryName

---

But lipo doesn't make the file ARM64 or whatever you're asking. You'll need to use lldb for 64bit portion of the Binary.

if follow what you've said, is the size of binary file reduce? that's my concern. i cant run ida for file that exceed 30 over MB

No, it doesn't decrease the Binary size by removing arm64. It just swaps the header.

You'll need to use a tool which thins the binary..

Thanks DIDA, one more question. the old way that you use lipo the decrease the binary size is this method still work to the new game like MC5 or DH5? i want to reduce the unwanted portion of the binary..

I'm not sure to be honest, haven't tried it but I'm guessing it should work.

If you want just the Armv7 binary for DH5, get it from the hack topic btw
