Install CM10.2 Jelly Bean 4.3 custom ROM on Sony Xperia Z

Sony Xperia Z is one of the many devices that are not complete without Android 4.3 Jelly Bean. Thankfully, developers were aware of this, so one of them came up with CyanogenMod 10.2 version (or CM10.2 in short).

Apart from having protection against dust and water, your Sony Xperia Z deserves to sport the Android 4.3 JB version. A stock firmware does not have a lot of customization options for a gadget. The CM10.2 does. And with it, your device will have an improved Linux kernel, virtual surround sound, permission manager, the possibility to enjoy Bluetooth connection with gadgets of low power and many other new features.

Requirements

The update file will become yours once you are done with these pre-requisites first:

After you are done with this upgrade stage, your handset will not have its warranty anymore.Sony-Xperia-Z

Instructions

  1. To begin the guide on a good note, download Gapps from here and the Jelly Bean 4.3 CM10.2 custom ROM (file name: cm-10.2-20130926-NIGHTLY-yuga.zip) on your laptop.
  2. Then grab hold of the Xperia Z, plug it to the notebook and then do this: take the files from the notebook and send the both of them to the handset’s SD card root (but don’t unzip them). Unplug the devices from each other.
  3. Now do the following: power the device off and enter the same in Recovery Mode; by doing this: press Volume Up a couple of times while the device is booting; as soon as the screen of the recovery tool shows up, you need to stop.
  4. The content of your smartphone should now be wiped with the help of these instructions: opt for Factory Reset/Wipe Data, confirm, return to the Recovery Menu, choose Wipe Cache Partition and then opt for Wipe Dalvik Cache from “Advance”.
  5. Then opt for Install zip from SD card. When done, select Choose zip from SD card, find the update file and choose it via “Power”. The confirmation of this task is done like this: opt for “Yes – Install cm-10.2-20130926-NIGHTLY-yuga.zip”.
  6. The CyanogenMod 10.2 firmware will then end up on your Xperia Z. To get the Google Apps package on the same phone: repeat the actions which flashed the previous package. Return, after the two installation phases are over, to the phone’s Recovery Menu.
  7. When you are in that location, you should select the restart option; then wait for the restart of your handset. Wait a couple of minutes now; the update firmware will then be on your phone for good.
  8. However, in case the new ROM is not what you had in mind, you can always get the device back to its former ROM by doing as follows: enter the Sony Xperia Z into the Recovery again, then opt for “Backup & Restore“. Choose your ROM from a list that will pop up in no time at all. Then wait to have it returned where it should be.

If you wish to get data from Titanium Backup back on your phone, don’t.

After the update tool is on your beloved smartphone, you should expect some minor bugs to visit you now and then. You will get rid of them once the developer upgrades it to a superior version.

Should the smartphone remain stuck in boot loop, you can do this: opt for Wipe Cache Partition, then choose Wipe Dalvik Cache. Restart your phone to complete the process.
