How to update Sony Live With Walkman to the new version Android 4.2.2 CM10.1 on.
Every developer periodically releases the bug fix versions. Specially when I’m writing this post, this ROM under the development. So when you are updating it to the latest version, you don’t need to perform “Wipe data/factory reset” step. But you have to “wipe cache partition and “Wipe dalvik-cache partition” steps.
Moreover you have to install the Gapps zip file again (no need to download, just use old downloaded zip file). If you skip the Gapps installation, when you boot your phone, your Google account data will be deleted.
