Help/Support HELP: APP Crash after Patching the BIN File

[MrTepes 48 iPad Air 2 9.3.3]

Hi all :-)

I can´t open an App after Patching the BIN File on IDA. I followed this steps:

 

1. I CLutched the app

2. I Extracted the BIN and opened on IDA

3. I Used "Strings" Method to modify it with a HEX Editor

4. I Saved the new BIN and after that i put it back in the .App with 777 Permissions

 

After that and when i tried to open the App again to test it with the new BIN the App Crash all the time.

I asked on the Chat and somebody asked me to use "ldid" to resign the BIN, but when i did it nothing happened (no errors or other messages:-)

 

Now i´m stuck cause i don´t know what to do to make the Modified BIN works in the APP.

What could i do to make it work?

 

I hope i explained myself (english is not my language:-)

 

Thx a Lot to all of you in Advance for your Help!

It's ldid -S with a capital S.

Does a normal bin work? Cracked but no modifications?

[MrTepes 48 iPad Air 2 9.3.3]

@DiDA YES, if i put back The original Bin The app works fine.

 

i have a question though. I put The patched Bin in "var/mobile"

after that i cd /var/mobile and "ldid -S (name of The Bin file:-)

when i see /path/to/bin i assume that path is ok, right? And in The other hand, as i don' get any Message from ldid... Do i need some kind of response/Message from ldid telling me everything is ok? Or if nothing happens (just a couple of seconds waiting and that's it:-) it's ok/done...

i don't know if i explain myself....:-)

The game probably has security but try not cding and just using /var/mobile/binaryName because I think for current directory it's ./binaryName
