How to update Cyangenmod 10.1 to 10.2? I have Cyangenmod 10.1.3 installed on my Xperia Z. When I tried to download Cyangenmod 10.2-20131101 nightly build in my phone's settings, no error but it silently failed after some time. I tried again but the problem persists.  

Any idea what went wrong?  

Am I supposed to download the zip file, copy it to my phone and boot into recovery mode to do a manual installation?
You should follow these steps:


Download the relevant ZIP file from get.cm
Copy the downloaded ZIP file to your devices storage card
Using an app such as Titanium Backup, do a complete backup of all your installed applications.
Boot into recovery, and follow these steps:

Wipe data (all data)
Install the zip file as usual

Once done, reboot device.
Using the backup app, restore your apps.
Reboot device.


You will now be running the latest version. The data wipe is highly recommended, but your device should still work without it - you must wipe the dalvik cache at the very least however, or you'll get a boot loop.

Important Note

If you use google apps (GApps) then you must make sure you download the version for CM 10.2. If you do not, you may experience compatibility errors.
