Update Motorola Droid Razr M to Jelly Bean 4.2.1 with Eclipse Custom ROM
If you want to go “dark” and use the Eclipse custom ROM firmware on your Motorola Droid Razr M, now you will be able to do so, as thanks to those of xda-developers the Android 4.2.1 Jelly Bean based software has been made available and can anytime be flashed on your Razr M device. Therefore, during the present tutorial I will show you how to prepare your smartphone for the update operation and then, by using dedicated steps, you will learn how to install the Eclipse JB 4.2.1 ROM on your Droid Razr M handset.
The Eclipse software is popular among Android users (the platform isn’t available only for the Motorola Droid Razr M) due to its dark UI and powerful features and apps that can be used for powering up the performances of your device. Also, in our case, Eclipse brings Android 4.2.1 OS, so you will be able to enjoy the same on your own Razr M smartphone. As mentioned this software is being perfect especially if you want to improve the performances of your phone and also change its looks. Well, after flashing the Eclipse system you will be able to customize and optimize the internal system of your Droid Razr M, gain more speed, upgrade the battery life, add a new UI and a lot more.
If you still haven’t decided whether to apply the Jelly Bean 4.2.1 Eclipse firmware or not, I recommend you to take a look over our source page (go here); you can find there everything (features, capabilities, apps and so on) related to the software, this being the perfect way in which you can make a proper background idea about the same. Then, return here and resume the rest of the lines from this tutorial. Do read everything from below, or else you will risk in bricking your device.
The first to begin with is the backup process. As we are dealing with a custom ROM and not with an official OTA update, you have to apply some preparation tasks before heading to the proper flashing process. And, as usual, a backup must be completed before applying anything else. Therefore, save everything you need to, starting from contacts, messages, market apps and ending with the current ROM. Later, a wipe will have to be performed so all of your personal info will be erased.
Now, when we know that the data is in safe hands, there are other and more complex operations that must be completed. And first, you will need to root the Motorola Droid Razr M. By rooting you will provide access to the internal system of you device, which means that the Eclipse custom ROM will be able to make changes to the same. You cannot update your Razr M to custom Jelly Bean 4.2.1 without previously gaining root access. The, after rooting, you need to get and install a custom recovery image (like CWM recovery) on your phone. This tool will be used on the flashing procedure, so it is important to complete these pre requisites.
Be aware as by rooting and updating with a custom firmware you will void the Motorola Droid Razr M warranty. Of course, you can restore the same if you reset the flash counter; this can be done by downgrading your handset to stock ROM, or by updating with an official software released and provided by Motorola.
Up next, just before starting the update tutorial, make sure that: you can use a computer, or notebook that has access to internet; the smartphone and its USB cable are near you; you are deactivating or uninstalling the security programs that are installed or running on your computer and handset; enable the USB debugging option on your Razr M; charge the battery of your device if there is less than 60% power left.
Finally, it should be clear for you that this step by step guide has been developed and can be applied only by the Motorola Droid Razr M users. Trying to install the Android 4.2.1 based Eclipse custom ROM on a similar handset will make you brick your device, so don’t mess things up.
