iOS 9-9.0.2 jailbreak Tips and Tricks:Pangu Team website (screen-shot)

Earlier this week, Chinese jailbreaking code developer community Pangu Team released their iOS 9 based jailbreak tool to the Apple devices. However, some early adaptors of the new Pangu iOS 9-9.0.2 jailbreak tool have complained that the Cydia app abruptly crash or sometimes, it fails to open at all, thus rendering jailbroken iDevices crippled. Users will not be able to neither install performance enhancing tweaks nor custom features.

[Note: Cydia is a software application for iOS that enables a user to find and install software packages on jailbroken iOS Apple devices such as the iPhone, the iPod Touch, and the iPad.]

There is no word from Pangu Team on when the new update would be released to fix this issue. Thankfully, industrious folks at Redmond Pie come up with a workaround to make Cydia app work properly.

Disclaimer: This procedure is very technical and should be performed by a person with sound knowledge of rooting (or manual software installation) Android devices. If the step-by-step installation process is not followed properly, there are chances of the smartphone getting bricked or being permanently irreparable. IBTimes India cannot be held responsible for any damage or claims from readers if the procedure does not yield the required results or if the smartphone is bricked. Hence, users are advised to proceed with caution.

Pre-requisite:

  • Make sure the device is running the latest Apple iOS 9.0.2
  • PC must also be running the latest Apple iTunes software
  • Back-up everything

[Launch iTunes >> select- photos, contacts and others >> Right Click on your device >> Select back-up and let it sync]

  • Take your device and go to

Settings >> General >> Reset >> Erase all contents and settings >> Erase iPhone

Here's how to fix Cydia crash/ not opening glitch:

Step 1: Set your device in DFU (Device Firmware Upgrade) mode

  • to enable it, first connect the device to the computer and open iTunes (on PC)
  • Long press power and home/ Touch ID button
  • After 10 seconds, leave power button, but do not pull your finger off the home button, until the iTunes (on PC) pops the message – 'you are in DFU' mode

Step 2: Once DFU mode is enabled on the device, hold the 'Shift' key on Windows PC (or Option key on Mac PC) and tap –'Restore iPhone...' button on iTunes application

Step 3: Download new Pangu iOS9.0-iOS 9.0.2 jailbreak code v1.0.1-- HERE -- on to your PC [How to download and install -Tutorial]

Step 4: Once the device is jailbroken (with v1.0.1), turn off the Airplane mode and also make sure either the Internet data pack or Wi-Fi is on.

Step 5: Now, click on the Cydia icon and allow some time for the app to fully load. Then, the device will reboot to complete the procedure.

If the readers have followed the above steps in the right way, then, it is unlikely that Cydia app will crash again.
