How to Install a .deb file

First of all, what is a .deb file ?

It is a package which contains everything you need to install an application (often coming from Cydia). The package is edited by hackers, they modify the code lines and then it becomes a cracked application.

 


There's different ways to install a .deb file, we will the main ones :
1st method : Mobile Terminal

 [Steps 2 and 3 are only if you never installed a .deb file with this method]

1/ Download the .deb file you want (example : LockInfo)
2/ Start Cydia, go to "Search", type "Mobile Terminal" and install it


3/ Repeat step 2 for "OpenSSH"

 

4/ Start "MobileTerminal"



 

5/ Type the following commands :
  • su  (press return)
  • alpine  (press return)  /!\ You won't see the typed password then don't worry /!\
  • dpkg -i nameofpackage.deb  (press return, replace nameofpackage with LockInfo for the example)
Note that you can rename the .deb file like 1.deb (it's easier to type)
 

6/ Reboot



2nd method : iFile (+ Safari Downloader)

Required :

* a jailbroken iPhone

* OpenSSH installed (search in Cydia)

* afc2add 1.01 fix usb if jailbreak was done with Blackra1n.

* copy the file iTunesMobileDevice.dll in the installation folder of the SSH software used.

* display the hidden files

* the file iTunesMobileDevice.dll is there : C:\Program Files (x86)\Common Files\Apple\Mobile Device Support\bin



1/ Start the SSH software you want (WinSCP, FileZilla, iFunBox...) and connect to your iPhone

3/ Install the .deb file just by clicking on it
