iOS Soft Dev Pack to Jailbreak iOS 7.1 on iPhone 4

Recently, a Russian hacker Smolk published tutorial on how to jailbreak iOS 7.1 running on iPhone 4, but the jailbreak is tethered.


Below is a detailed tutorial.


  • This tethered jailbreak only for iPhone 4 running on iOS 7.1.
  • Before jailbreaking, make a data backup for your device.
  • Make sure your computer installed JRE 32-bit (download link)
  • A tethered jailbreak means that whenever your iPhone is turn off you need to do a quick “Just boot” to get it back on.


Step 1: Download iOS Soft Dev Pack JB v2  from the this link (Only for Windows) which is a software based on Opensn0w (created by Winocm)

Step 2: Launch this tool after it downloaded.


Step 3: Connect your iPhone 4 to computer and click “tethered jailbreak iOS 7.1 for iPhone 4”  in the lower left corner.


Step 4: You will see 3 easy steps appear on the screen shown above, click on “1)Run SSH RD Tool” A window as below will pop up, which takes a while.

Run SSH RD Tool

Step 5: Then manually enter your iPhone 4 into DFU mode, you will see the codes running until the green success appear.


Step 6: Now, your iPhone is like this. After the green success appears, do not close the above white window, click on “2) Run SSH Connect” then there will be a black window.

Please confirm whether the following code appears:

Mounting /dev/disk0s1s1 on /mnt1 ..
Mounting /dev/disk0s1s2 on /mnt2 ..
If not, please click re-click 2) Run SSH Connect, until the black window and the codes appear.

Step 7: If all goes well, do not close the black window, click the button “3) Jailbreak data send” also a black window appears.

Step 8: Wait until the windows automatically closed, the phone will reboot, and then there’s a iTunes & USB logo, then choose the phone model belongs your iPhone belongs from the“Tethered Boot”buttons, model can be viewed at the back shell of the phone.

Step 9: But no Cydia icon after reboot, do not worry, don’t touch your iPhone, over forty-five minutes, the phone automatically restart, iTunes & USB appears again, then click the button again,then you will see Cydia icon after the device reboot again, but still need to wait until phone respring. Wait a while, you can enter cydia, Congratulations, iPhone 4 is jailbroken.

This jailbreak utility is new so you may faced some weird errors or unable to jailbreak your device. Just try a few times and it should work. I tested it on my iPhone 4.

    Hello! greetings…

    I am confused step 9.

    Step 9: But no Cydia icon after reboot, do not worry, don’t touch your iPhone, over forty-five minutes, the phone automatically restart, iTunes & USB appears again, then click the button again,then you will see Cydia icon after the device reboot again, but still need to wait until phone respring. Wait a while, you can enter cydia, Congratulations, iPhone 4 is jailbroken.

    It says “…thenclick the button again,..”.

    What button do you mean here?
    What I did, was, I clicked the “Teether button ios 7 model 3.1”. I rans well but most applications and settings don’t work; Wifi, music and others.

    Now I repeat the process. I am now on step 9, at second reboot with itunes-USB logo.
    After 1st reboot without cydia the phone will reboot and pops up the itunes-USB logo. So you said I will wait for 45 minute to come back from itunes-usb logo.

      Same here. Its all success but my iPhone 4 restarts and then got stuck at recovery mode! What do we do? I tried redoing all the steps and again, success but unfortunately, the restarting issue still occurs.
