Patching libg.so

[clugh]

dd actually does the patching. xxd is simply used to write the key to a file using its hex representation and read them back out for verification. That said, you can use the hex editor of your choice to manually update the key in libg.so, though this method is more prone to human error. If you use this method, note that the offsets are listed in base 10 (decimal), so you may need to convert them to hexadecimal before using them.

To do this with HxD:

1. Open libg.so.
2. Click Search -> Goto... in the menu bar.
3. Enter the Offset, check the dec radio button, and click Ok.
4. With the new key in your clipboard, click Edit -> Paste write.

Note: Be sure that the key is pasted into the hex values on the left, not the ASCII representation on the right.

I did just that, and when I try to lunch CoC, it just returns to main screen of android. If I restart, I can lunch clash of clan and everything works, but I don't see anything on coc-proxy-csharp except "Listening on 0.0.0.0:9339

UPDATE: Now I am stuck on Loading, it seems that it is unable to connect to the proxy

Sounds like you aren't properly routing the packets. What method are you using? Are the client and proxy on the same local network? If not, are you forwarding port 9339?

For simplicity, I suggest using Hosts Editor (requires root). Do the initial tests on an unpatched version of game, so if your base loads, you'll know the packets aren't being rerouted. If it fails, the proxy should have a note about not being able to decrypt the login packet; otherwise, it isn't receiving the packets.

So it seems like the packets are being received, now I am getting this error:

Listening on 0.0.0.0:9339 ...
System.IO.DirectoryNotFoundException: Could not find a part of the path 'D:\CoC\coc-proxy-csharp\bin\messages\definitions'.

EDIT: I fixed this part. I got another error. I will attempt to fix it and will update if I need any help

Thanks for being so helpful <3

Do you mind posting your solution, in case anyone else stumbles on the same error and ends up here?

From the sound of it, you hadn't initialized the repo's submodules:

I don't know what caused my first issue, but I managed to fix it simply by putting the messages folder in the D:\CoC\coc-proxy-csharp\bin\

My other issue consisted of not having the pulling and pushing to the right path using adb, since I am using Kitkat I needed to use the path listed on the wiki
