Help/Support App crashes after modifying binary

jay181020 · January 2, 2016

Here's the rundown on what I'm doing from beginning to end

I use clutch 2 to dump everything

Then I use ifun box to transfer everything over to computer

Once over to computer I load the binary into Ida

Being that I have been dealing with a lot of sub_xxx games I find what I'm trying to hack

Once I find the offset I load the binary into hXd

Change what needs to be changed then out the binary back into the game folder

And transfer it back over to my phone

Why don't you do the hex editing in IDA?

@diversityy I always change everything in Ida and see how everything looks and fan out but I thought you couldn't save the actual changes to the binary through Ida ?

Set the binary permissions to 777

This is mean click all of them

read, write, execute

Also 755 mean

user: read, write, execute

group: read, execute

world: read. execute

I've done that but the app still crashes ... And I've been hacking for about 3+ years on android and as far as signing the app etc etc was pretty much in the program I was using so do I need to resign the binary or something

If you removed the ASLR and you have iOS 8.3+ then yes sign the binary
