Bypass "ptrace: Operation not permitted" or get around small dump size problem


5 posts in this topic

Recommended Posts

Have "ptrace: Operation not permitted" error when you try to debug a game using GDB? Follow these steps

 

 

 

 

"PID" stands for Process ID

 

 

 

 

 

The game is EDEN Avalon Legends (th.co.tdp.eden).

 

 

 

 

 

Turn off the Advanced Task Killer app, if it is running.

 

 

Open the game, and press the HOME button to minimize the game.

Type

 

 

 

 

 

dumpsys meminfo

 

 

 

 

 

to view all running processes.

Take note of the number next to "pid" (PID stands for "Process ID" and changes everytime a process starts). In my example, I'll take note of the number "383".

 

 

 

 

 

Now, using the PID you just noted, type:

 

 

 

 

 

 

 

 

 

This will give a list of clones of the main PID and depending on the game, can attach to it regardless of if ptrace is denying the main process id (PID), if that makes sense.

 

 

 

 

 

Attach to a clone of the process

 

 

 

 

 

gdb -pid xxxxx

 

 

 

 

 

Example:

 

 

 

 

 

gdb -pid 4546

The symbols are loaded which means the game is debugged

Dump as normal with gcore

 

 

 

 

 

gcore /sdcard/DUMPEDFILE

 

 

 

 

 

Do not worry about any warnings like these you may read in the Terminal app:

Extract the DLL file as normal with cracked Winhex

 

 

 

 

 

Proof:

But EDEN Avalon Legends will not run if you replace the modded DLL file, due to crc32 check.

Note: Games such as GrandChase M doesnt work. Even the clones found through "ls -l" still deny ptrace it basically depends on the securty the game has but its good info and you never know what seems a really hard game might just work as did avalon legends which like 4 i know are trying to bypass ptrace for

Is there a way to encrypt the files again after modding? the games seem not to work with the decrypted dll's in place

i don't know but encrypting it back doesn't help since the decryption key is different
