The Droid Razr is still a decent Android device that has enough power to offer even for an experienced user. However, due to hardware limitation, Motorola will no longer release OTAs for this device. That’s why, if you still want to receive and enjoy the latest Android features and apps on your own Droid Razr, you should choose to update your phone with a custom ROM firmware. Well, in that matter, I have something great for you: the new CyanogenMod built, which is based on stock Android 5.1 Lollipop OS.
Thus, CM 12.1 – this is the ROM I am talking about – has been customized and optimized especially for the Motorola Droid Razr. Unfortunately, this is not an official release provided by the CyanogenMod team as the update is currently developed by those of xda-developers. So, this is an unofficial variant of CM12.1 based on stock Android 5.1 Lollipop OS that can be anytime downloaded and installed on your Droid Razr.
However, this is only the alpha version of the firmware, so do expect to notice some minor bugs and software related issues included on the main CM 12.1 platform. But, if we are to believe the users who have already flashed the Android 5.1 OS, the system is good enough for a daily use. Therefore, you can now tweak your Droid Razr while experiencing the latest built of CyanogenMod.
Don’t forget that this is a custom ROM and not an official Android update provided by Motorola or by Google. So, if you choose to update your Droid Razr with CM 12.1, remember that you are about to complete an unofficial update procedure – the warranty of your device will get void and if you aren’t an experienced user, you can end up in bricking your phone (learn all the risks implied by checking this dedicated tutorial).
Also, for being able to install the Android 5.1 Lollipop CM12.1 OS, first you have to root your Motorola Droid Razr. Then, you have to install a custom recovery image (like CWM or TWRP recovery) on your device and finally you should save the current ROM from your phone for being sure that you can afterwards complete a downgrade operation.
