Meaning, we need no hex editor to edit it. And the save file is also a plain text file. There are even easier problems, such as the game Aqua Pet. Now, we can hex edit the save file freely as we like. Push the newly edited library, then start the game. So, to make the game load the plain binary save file, we need to disable calling “decode” function in the “load” function as the method discussed above. If it is a plain binary file, then we success! If not, try until you want to give up.ĭo not restart the game yet, because the game will load the encoded save file, not the plain binary save file. Now, check the newly saved file with hex editor. Run the game, load the save file, save the game, then exit. Make sure backup the original library and also the save file. Then, we can objdump again to check whether we have disabled the function call.
That means, we disable calling “encode” function in “save” function. Edit the hexadecimal value of the opcode that calls the “encode” function within “save” to “00 00 00 00”, this will produce NOP operation. Use a hex editor to open the shared object. In this case, it will be quite easy to solve the problem. Study what the functions they are calling.įor example, in the “save” function, it might contain a call of “encode” function, then only “write” the buffer. This is because normally, they will call encrypt or encode before write the file (save). We might find some functions such as “encode”, “encrypt”, “decode”, “decrypt”, “save”, “load”. And also, need to look for open file, read or write file, and close file. Now, what we can do is just study the functions. This will create “asm.txt” which contains the disassembled data. path-to/objdump -dC libdhunter.so > asm.txt #pull the library file first, not doing this in adb shell

The objdump can be obtained from Android NDK package. shared object (.so).įor example, if there is a library called libdhunter.so, we need to use objdump (ARM target, not x86 or x86-64 target) to disassemble the shared object. So, my only solution is to edit the library file, i.e. We cannot understand anything about the file. Advanced problem and solutionįor other games, the save file is really a pain. ( Please always make a backup before editing). We can understand the file with the hex editing, such as the value of the coins, the level of the weapons, the status of the hero such as strength, vital, hp, and so on. I push it to /data/local/tmp folder, so that I can use it without pulling and pushing the file.įor some games, the save file is plain binary file. I personally wrote a small command-line tool, so that I can do hex editing in adb shell. Use a hex editor, such as bless, ghex, hexedit, etc. So, pull the save file you want, the name such as Save0.dat or similar name.
Now, since we can access those data files in /data/data folder, meaning that we can pull them, edit them, push them back. So, to edit the save file, we must have the knowledge and experience on hexadecimal editing. My hacking method is not memory editing, but save file editing. This folder contains the game save data and also some libraries. After we gain the “#” from “adb shell” (refers to my previous post), now we can see all the files in /data folder. Okay, this is the main purpose I learn about Android rooting. Thank you.įrustrated with some Android games? Want to hack? Want to kill the monsters with one slice? So, if you are asking about a specific game, please find it on other channel.
#RESPAWNABLES HACK 2016 HOW TO#
And what I shared here is only how to hack the games in general way, without permanent root the Android. Sorry to say, I am not that expert in hacking those games, and I don’t have much time to play and hack the games. Read this first: Quite a lot of readers asked me how to hack this game or hack that game.
