C3FFF0E · April 16, 2015

Ok. Just to let you all know, my iDevice is: iPad Air, 64bit, arm6, v7.0.4

***Instructions***

1.) Go to this website: https://code.google.com/p/networkpx/wiki/class_dump_z

2.) Download the "0.2a" version.

3.) Once it finish downloading, open it up on "iFile/Filza".

4) Find the "class-dump-z 0.2a.tar.gz" then "Unarchiver it" using the iFile/Filza.

5.) Inside the file, you'll going to see this documents:

iphone_arm6 (Folder)
linux_86x (Folder)
mac_86x (Folder)
win_86x (Folder)
LICENSE (.txt File)
README (.txt File)

6.) Delete these following documents: (You won't need them)

linux_86x (Folder)
mac_86x (Folder)
win_86x (Folder)
LICENSE (.txt File)
README (.txt File)

7.) Open up the folder "iphone_arm6". Inside of it, you'll going to see these following: (You made also delete the "README" .text file)

class-dump-z (Important File)
README (Not so important file)

8.) "CUT" the "class-dump-z" file and paste it here "/usr/bin/*HERE*".

9.) Be sure that you have install "pcre" from Cydia to run the class-dump-z on your arm64 iDevices.

10.) You're DONE!

NOTE: If you want to know if the class-dump-z is working also to know some basic commands, simply type this on Mobile Terminial:

class-dump-z

or

class-dump-z --help

NOTE: You must sign-in first as "ROOT".

username: su
password: alpine

11.) To use that class-dump, you may type this on the Mobile Terminal:

class-dump-z -H /var/""/"Binary.app" -o /var/""/"The folder where the class-dumps will go".

Example: class-dump-z -H /var/mobile/1 -o /var/mobile/2

***Problems***

I somehow saw that the binary that you dump will not correctly go to its "Folder" path and the result will "null" or no files inside.

To fix this:

1.) You must "Clutch" first the app you want to class-dump.

2.) Once it finish, uninstall the app you have downloaded and install the crack one.

3.) Copy and paste the crack binary on your desire folder. (I recommend putting it on /var/mobile/*Folder*/***HERE***)

Overview:

/var/mobile/*Your Folder*/***PUT HERE YOUR CRACK BINARY***

To clarify:

1.) Make a folder on /var/mobile/
2.) Then put the crack binary inside of that.

4.) This is what you'll going to type now on Mobile Terminal:

class-dump-z -H /var/mobile/*Your Folder*/*Name of the crack binary* -o /var/mobile/*Your folder*

Example:

class-dump-z -H /var/mobile/hack/tinytower -o /var/mobile/hack

Overview:

All the class-dump files will now successfully extracted on the designated folder.

5.) Enjoy & Good Luck on finding the correct Class-Targets!
