Update Motorola Defy and Defy+ with Jelly Bean 4.1.2 CM10 Custom ROM

The Motorola Defy and Defy Plus handsets can now be updated with the latest version of the Android system, the Jelly Bean 4.1.2 one, as those of xda-developers had managed to develop a new firmware based on the CM10 custom ROM. As usual, during a complex step by step guide we will be checking in how to apply the mentioned CM10 update on your Defy, or Defy+ smartphone. But before heading to the proper steps, you should first complete the pre requisites, which actually represents the most relevant part of this tutorial.

Now, you should learn how to install the Jelly Bean 4.1.2 based CM10 custom ROM firmware on your Motorola Defy / Defy Plus if you want to power up the performances of your phone by adding extra features into its internal system. In this way you can optimize and customize the OS so that you can receive more power and speed from your device. You should know though that the present update isn’t an official one, so the operation you are about to perform has nothing to do with Motorola. Furthermore this is also a beta release of the CM10 platform, meaning that you won’t receive a perfectly stable and smooth version of the same.

For the full list of features and reported bugs, you can anytime check our source page from here. Now, don’t worry as the devs are constantly working on improving the present CM10 update that suits your Defy and Defy+, so the bugs and issues will shortly be resolved and removed. As a final note regarding to these aspects, you must know that this is not the only OS improvement available for your Motorola device. You can easily search through our how to section for more step by step guides that can be applied for your Defy smartphones, so don’t hesitate and use the same.

Anyway, the present tutorial can’t be performed unless your devices are already rooted. If not, the CM10 ROM will not run and you will not be able to install the Jelly Bean 4.1.2 update. Be aware as by rooting the warranty will get void, so if you damage the system, or brick your phone, you will be by yourselves, there’s no one to help you out. That’s why you must always follow a how to guide and not to apply things by yourselves. Afterwards, you can restore the warranty if you choose to downgrade to the stock ROM, or if you want to update your Defy / Defy Plus with an official firmware provided by Motorola.

Then, after gaining root access, you must install a custom recovery image on your phone. I recommend you to flash the CMW recovery tool as it is the most popular recovery used by worldwide Android users. Up next, you must also backup the data which is being stored on your handset’s internal storage memory, as a full wipe of the system will be required. Therefore, take your time and save all you need to. For that, you can use our suitable backup and restore guides. The tutorials are easy to understand and to apply, completing them taking only a couple of minutes.

Finally, you must ensure that you can use a Windows running computer, your smartphone and of course its USB cord. The CM10 ROM can be installed only if on the computer and Defy / Defy+ there are no security programs installed. Next, enable the USB debugging option from your phone by going to “Settings -> Applications -> Development -> USB debugging”. Also, check the battery status and if there is less than 60% power left, charge the battery of your smartphone first. Apply this method only for the mentioned devices and not for similar ones as you can end up in bricking them. And with that you can safely head to the proper steps from below.
