Every smart phone maker is busy rolling out the latest version of Android 5.0 L to its devices. Sony also joined the list by coming up with Android 5.0.2 L roll out for its Flagship series – the Xperia Z2 and Z3. The update will be made worldwide. Xperia Z1 users can expect the update for their devices within a month.
Sony is allowing Xperia Z1 users to install CyanogenMod CM12 ROM. So if you are impatient about moving onto the new Android v5.0.2 and can’t wait until the release comes, you could move to the new custom ROM. But the new CM 12 version hasn’t completed its testing phase and may have many unfixed bugs. It is just a nightly update and the main version is currently under development.
A good way to ensure that no compatibility issues arise is to update your third-party add-ons. Otherwise certain system files in CM will either remove or ignore incompatible apps. The only way to get the functionality again is to install some compatible app.
If you want to move back after upgrading to CM12’s night update, make sure to have a backup first. It is not possible to downgrade without clearing everything. You should be installing a recovery compatible with Android L before installing the new CyanogenMod CM12 custom ROM. The device should also be rooted and make sure that you install the nightly update on only Xperia Z1.
The ROM installation will require that the phone’s memory be cleared. It will be essential to take a backup by installing CWM Recovery. Besides, the phone should have its USB drier installed on your PC, else it will not be recognized.
While Sony rolls out the Android L v5.0.2 update on Xperia Z2 and Z3 smoothly, it can be a rough road for Xperia Z1 users. So if you want to be on the safe side as a Z1 owner, it is recommended to wait until Cyanogen has a stable update.
