HTC One S to Android 5.0 Lollipop Using CyanogenMod 12

Android’s characteristic as an Open source project makes it very unique and flexible in the sense that even devices that are not supported by OS updates can still get a version of the desired OS. HTC One S can now have CyanogenMod 12, and before proceeding with the installation, it is important to note the following:

  • As an unofficial version, the installed update can have bugs and issues with it.
  • Calling can become troublesome because of bugs, but this can easily be solved by rebooting the device
  • Location Notifier in the Status Bar is not functional
  • Wi-Fi hotspot is not functional

 

This article will provide you with a step by step guide to upgrade your HTC One S to Android 5.0 Lollipop using CyanogenMod 12. Before beginning the installation process, here are some notes that you have to consider:

  • This step by step guide will only work for HTC One S. If you are not sure about your device model, you may check it by going to your Settings menu and clicking ‘About Device’. Using this guide for another device model may cause bricking, so if you are not a Galaxy Note 2 user, do not proceed.
  • Your remaining battery percentage should not be less than 60 percent. This will prevent you from having power issues while the installation is ongoing, and therefore will prevent soft bricking of your device.
  • Backup all of your data and files to avoid losing them, including your contacts, messages, call logs, and media files. This will ensure that you will always have a copy of your data and files. If your device is already rooted, you may use Titanium Backup. If you already have an installed TWRP or CWM custom recovery, you may use Nandroid Backup.
  • Also backup your mobile’s EFS
  • Your Samsung Galaxy Note 3 should be rooted
  • You need to flash TWRP or CWM custom recovery
  • Download CyanogenMod 12
  • Download Android 5.0 GApps

 

Note: The methods needed to flash custom recoveries, roms and to root your phone can result in bricking your device. Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers. Be responsible and keep these in mind before you decide to proceed on your own responsibility. In case a mishap occurs, we or the device manufacturers should never be held responsible.
