Samsung Galaxy S4 Android 5.0.2 Lollipop Update: How to Install CyanogenMod [Official] CM12 Nightly Custom ROM

Anonymous 05:27 , , , No comments :

American mobile software developer team, Cyanogen, has released the much-anticipated Android Lollipop custom ROM CM12 milestone series to Samsung's 2013 flagship phablet, Galaxy S4 LTE model.

This new CM12 milestone software is a nightly version of AOSP (Android Open Project) 5.0.2 Lollipop.
We would like to remind our readers that this nightly version is unstable and has some un-tested bugs in it. So, we advise you to go through the whole tutorial article before going ahead with the custom ROM installation.
Some of the features that are missing in the nightly version are:
  1. Theme Engine
  2. Quick Settings reorganization and customization
  3. Quick Settings Ribbon mode
  4. Navigation bar reorganization and customization
  5. Sound panel customization
  6. Lock-screen quick unlock
Cyanogen confirmed that the development of the stable firmware is 85 percent complete and would be rolled-out soon. Until then, users can upgrade their device with nightly update.
Prerequisites (Things to remember before installing the CyanogenMod CM12 Nightly):
  1. Users are advised to update their third party add-ons to ensure compatibility
  2. The CM backupscript.sh in recovery will ignore and remove incompatible applications from your system partition (these are usually non-CM apps that users have opted to install). You must install a compatible app (or app pack) to regain that functionality
  3. You can flash CM12 nightlies directly from CM11 M12 or CM 11 nightlies (no need to wipe), provided you read and follow the above-mentioned two steps
  4. Once on CM12 nightlies, you cannot downgrade to CM11 without wiping; if you are thinking of just exploring the release, then keep a backup of your existing installation incase you want to go back to it.
  5. Users must install Lollipop OS compatible recovery before installing the new CM12custom ROM.
  6. Make sure the device is rooted before going forward for custom ROM installation
  7. This new CyanogenMod CM12 Android 5.0.2 Lollipop firmware has to be installed on the Samsung Galaxy S4 GT-I9505 (with Snapdragon chipset) LTE model only; if tried on other devices, it might get bricked [To check your device model: Go to Settings >> About phone >> model number]
  8. Installation of custom ROM requires clearing of memory in the smartphone, so make sure to keep a backup of all the data by installing Clockwork Mod (CWM) Recovery/TWRP in the smartphone.
  9. Users make sure you have installed USB drivers on the PC, or else your smartphone (Samsung Galaxy S4 LTE) will not be recognized by the computer.
  10. Make sure your device has more than 80 percent battery as there is a risk of the smartphone getting temporarily bricked, in case the installation process is interrupted mid-way.
[Disclaimer: This procedure is very technical and should be performed by a person with sound knowledge of rooting (or manual software installation) Android devices. If the step-by-stepinstallation process is not followed properly, there are chances of the smartphone getting bricked or being permanently irreparable. International Business Times, India Edition cannot be held responsible for any damage or claims from readers if the procedure does not yield the required results or if the smartphone is bricked. Hence, users are advised to proceed with caution.]
