So... the same issue that I've had forever, the issue that made me stop making hacks... 

 

GDB, it just won't work...

 

I watch an offset, it changes in game, GDB doesn't even notice it...

 

Happens to every game, and if not, I get something like "osabi fail" or whatever when the value changes...

 

Yes, I check the offset before I watch it.. 

Yes, the binary is cracked and thinned...

Yes, I have removed it's ASLR and signed it...

 

I'm on iOS 8.4 (iPad Mini 2)

 

Anyone else who is having the same issue?

Anyone who knows how I can fix this?

 

I'm seriously tired off it.. 

I do the whole process of cracking, thinning, removing ASLR, loading to IDA and waiting.. then it always result in the same way... It just won't recognize the change of the value... :cry:

GDB made me to stop making hacks too... I had a different story It wouldn't attach to games or it would ignore changes and sometimes even crash :(

 

Goodluck buddy!

After the value changes, have you tried hitting CTRL + C (which momentarily halts GDB), and then continuing the process by hitting C?

 

I kinda forgot how it went.

Debugging on 8.4 didn't really work because Taig did something, I remember correctly.

Are you on Mac?

._. I know that it has worked on like 2-3 apps...

 

Tried on Mac and Windows :/

GDB sucks for watchpoints now. It used to only work with Unity games but the engine was upgraded and it doesn't even work anymore.

 

Use LLDB for watchpoints. You can find many tutorials here on it.
