Google's Android updates are always carried out in stages. This explains why some devices or subscribers receive firmware access sooner or later than others. For Samsung Galaxy S4 users still waiting for their devices to get the Lollipop treatment now have the option to upgrade via a custom ROM.

The latest update comes from the CyanogenMod team specifically via the CyanogenMod 12 custom firmware. Similar to what Google promised, the Android 5.0.1 custom firmware offers a number of fixes and under-the-hood improvements. Nonetheless, the team clarifies that the CyanogenMod 12 Android 5.0.1 Lollipop remains at its beta stage so users may have to wait for iterative updates from time to time for additional enhancements.

Prior to installing the update, users should:

-back up personal and other important data

-enable USB debugging. To do this, go to Settings > Development Options > USB debugging.

-root S4 handset

-charge the handset at least 60%

To install the update:

1. Connect the handset to the computer and transfer custom ROM's zip file to the device's SD card.

2. Disconnect the S4 from the computer.

3. Boot to recovery mode by pressing and holding the following buttons: Power, Home and Volume Up.

4. Do a Nandroid backup by selecting the following: Backup > backup and restore.

According to another report by Christian Today, Google has also been working on bringing the Android 5.0 Lollipop update to the LG G2 device while the Moto G will soon receive the Android 5.0.1 OTA update. The LG G2 information came from a leak showing the device running on the Android 5.0.1 OS. Users in Korea will receive the update first.
