How To Capture OTA Update on T-Mobile Revvl 2 Plus
The most basic and easy way to upgrade your T-Mobile Revvl 2 Plus is to wait for the airborne software update. It will knock into the device on its own. It's fairly an automatic process, but sometimes the automatic update gets stuck. You may not get to see the update even after weeks of the rollout of the software. Here you can search for the update on your own and capture it as well.
To do it, go to your device Settings > System > About phone > System updates > Tap on Check for Latest Updates. If the new software update is available it will show up with the recent changelog and the build number A4ZUMZI. Then just tap on Download to initiate the update process. Keep in mind to charge the battery of your device up to 50% to avoid power related issues. After the installation, you will be prompted to restart your device. Doit and the device will boot up with the new patch of January 2019.
