Sony just rolled out a new update for its Xperia Z1. The new update is based on the same Android 5.1.1 Lollipop, and brings nothing new and prominent but fixes an annoying bug. The bug we are talking about here is Stagefright. In the previous Lollipop updates, the Stagefright bug wasn’t fixed completely. Sony seems to be taking this Stagefright vulnerability pretty serious, so we are seeing this new update. This new update is reaching out the users through OTA and PC companion. Just in case you’ve updated, you must have lost the root access or in case you’re going to update your device, you will loose root access. Since the traditional rooting methods do not work on Android Lollipop, you need a different method to root your device running this latest firmware now.
We are going to overview a comprehensive method that will help you to install CWM or TWRP recovery and gain root access on your Xperia Z1 running this latest Android 5.1.1 Lollipop 14.6.A.1.216 Firmware.
Note: This method will work for both, locked & unlocked bootloaders.
1. This is only for Sony Xperia Z1 C6902, C6903 and Xperia Z1 C6906
This rooting method is only for the device mentioned above. Make sure that your model number matches the one listed above. To do so, go to Settings > About Device on your device and see your model number. Flashing this firmware on any other device will result in bricking it so make sure that you meet this requirement first of all.
2. Battery should be charged at least over 60%.
Make sure that your battery is charged enough to complete the flashing process. In case your battery is low and your device goes dead during the flashing process, you may end up soft bricking your device as it won’t complete the flashing process.
3. Backup everything!
Just to be on the safe side, you may consider backing up each and everything from your Android device. This is highly recommended so that in case anything goes wrong, you still have the access to all of your data and you can restore it immediately. You may backup everything as listed below.
- Backup SMS Messages
- Backup Call Logs
- Backup Contacts
- Backup Media – Copy your files manually to your PC or Laptop.
- Titanium Backup – If already rooted, use Titanium Backup to backup all of your apps, system data and other important content. If you haven’t rooted your device previously, skip this step.
- Backup Nandroid – If CWM or TWRP installed previously, otherwise skip this step and perform this at the end of flashing.
Note: This method will work for both, Locked & Unlocked bootloaders.
