Last updated: December 4, 2018.

The Sony  Xperia Z1

Sony had released a new update based on Android 5.1.1 Lollipop for the Xperia Z1.  This update basically fixes the Stagefright bug.  The update carries build number 14.6.A.1.216 firmware.

If you have an Xperia Z1 and have installed this update, you might welcome the loss of the Stagefright bug but not so much the loss of your root access.  Installing this update wipes root access in your device.

In this post, were going to show you how you can gain root access on an Xperia Z1 running Android 5.1.1 Lollipop 14.6.A.1.216 firmware.  We are also going to show you how you can install CWM or TWRP recovery.

Lollipop with build number 10.7.A.0.222 firmware with Sony Flashtool.

Prepare your phone

  1. This method should only be used with a Sony Xperia Z1 C6902, C6903 and Xperia Z1 C6906. Check your device’s model number by going to Settings>About Device.  If you use it with other devices you could brick the device.
  2. Charge battery to at least over 60 percent to prevent your device from running out of power before the process is done.
  3. Back up important contacts, SMS messages and call logs. Back up any important media files by copying them to a PC or Laptop.

 

Note: The methods needed to flash custom recoveries, roms and to root your phone can result in bricking your device.  Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers.  Be responsible and keep these in mind before you decide to proceed on your own responsibility.  In case a mishap occurs, we or the device manufacturers should never be held responsible.
