Update Galaxy Grand (I9082/I9082L) with CM12 Android 5.0.2 Lollipop Firmware

Android 5.0.2 Lollipop official update isn’t available for your Galaxy Grand (I9082/I9082L); but, you can already update your phone with a compatible Lollipop custom ROM. An unofficial release of CM12 has been made available by those of xda-developers and you can anytime choose to download and install the new firmware on your phone. In case you need help on the flashing process, don’t hesitate and follow this step by step guide. During the guidelines from below I will show you how to update your Galaxy Grand with CM 12 Android 5.0.2 Lollipop OS and also I will explain other relevant details that are related to the installation process.

CM12 for Galaxy Grand brings Android 5.0.2 Lollipop OS, the latest Android firmware that is available on the market. Of course, you will get a custom version of the stock Lollipop OS, as CM 12 is a custom ROM and not an official Android release. Thus, the firmware can be only manually installed on your Galaxy Grand and only by using the steps from below. The guide is complex and risky so you should read all the lines from below if you want to safely add CM 12 on your smartphone.

This release of CM12 is not official. The ROM is developed and offered by those of xda-developers and not by the CM team – thus this is not the Nightly build of CM 12 Android 5.0.2 Lollipop OS. Moreover, the firmware is still in development stage which means that minor issues might be included on the general platform. Anyway, according to the devs and to other users who have already flashed the update, CM12 works without problems on any Samsung Galaxy Grand device. Therefore, this Android OS is stable and smooth as there are no major bugs or lags reported – you can safely use the Lollipop OS on a daily basis.

Anyway, since CM12 is still in working phase, you shouldn’t complete this tutorial unless a Nandroid backup is ensured. With the Nandroid backup you can now save the current ROM that is featured on your Galaxy Grand. So, in the end, if CM 12 will not run properly, you will be able to return the stock and stable Android OS, without completing another complex tutorial.

Updating to Android 5.0.2 Lollipop with CM12 custom ROM is not an official operation. Your Samsung Galaxy Grand warranty will get void once you start to apply the steps from below. Thus, if you will brick on damage your handset, you will have to fix your phone by yourselves, or if you will take your device back to service, you will have to pay for the technical assistance. That’s why you should be careful when completing these guidelines.

Your Galaxy Grand must be rooted and installed with a custom recovery image, like CMW or TWRP recovery. This guide can be completed only if root access is ensured because a custom ROM must access and modify in built programs and processes; on the other hand, the update comes in form of a .zip file. You can install .zip files only by using a custom recovery image, so that’s why you now need to replace the stock recovery with a custom tool.

It is important to know that during the update operation a wipe will be performed. Your data will be wiped out and you can lose everything from the internal storage memory of your smartphone. Because of that a general backup should be applied. With compatible backup and restore apps from Google Play you can save your contacts list, call logs, text messages, EFS folder, market apps, internet settings, images, videos, audio files and other personal data, info and accounts.

CM12 can be installed manually; so a computer is being required. Your Galaxy Grand and your phone’s USB cable should also be near you as a connection between your devices will be required. This connection can be safely ensured only if on your phone USB debugging option is enabled – you can do so by heading towards “menu – settings – developer options”. Moreover, from your computer you might want to temporarily deactivate security protection. Do that because antivirus – like programs might interfere with the update process.

Updating your phone to Android 5.0.2 Lollipop OS will take a few minutes. It will be important to charge your Galaxy Grand before heading towards the steps from below. If the battery level is lower than 50% then your phone might get turned off during the installation process – and if that happens, your device might also get bricked. The CM12 custom ROM from below is compatible only with Samsung Galaxy Grand model number I9082/I9082L – try not to mess things up.
