Install a third-party ROM on your Android mobile or tablet It can be one of the best ways to give it a new life, especially if it is a relatively old device, which has stopped receiving system updates from its manufacturer. However, there are many mobile device owners who They do not dare to install ROMs on your devices, either due to ignorance or believing that it is a more difficult or dangerous process than it really is.
The reality is that installing a ROM on an Android mobile is a simpler process than it seems. In this guide, we explain how to do it step by step.
Install a ROM on your mobile step by step
Of course, before proceeding with the installation of a ROM it is necessary take into account some requirements. The first is the need to download a ROM compatible with your device. For this, we recommend you take a look at our list with the best third-party ROMs for Android, which offer versions for a large number of models from different brands.
In addition to that, in the vast majority of occasions we will need to have the bootloader unlocked. To do this, we recommend you take a look at our guide to unlock the bootloader of any Android device. You will also need to have a modified recovery, and for some of the procedures, it will be almost mandatory to have a computer with the installed ADB drivers on hand. When you meet all the requirements, you can continue.
Install a ROM via ADB Sideload
ADB Sideload is one of the best methods to install a ROM, and at the same time one of the least used. It is fast, safe, effective, does not take up memory on your phone … The use of TWRP Recovery has been highly standardized thanks to its compatibility with a large number of devices of all kinds, and many have already left out the command console, however, it is still an extremely useful tool and convenient, it can get you out of more than one trouble. Still, keep in mind that you still need to have a modified recovery to be able to install a ROM this way, unless your intention is to install an OTA or official factory image provided and signed by the device manufacturer itself.
The main advantage of a recovery is that you do not need a computer to perform operations such as installing a ROM, only for the first time you install it – and, in some cases, not even that. On subsequent occasions, you just have to download the ROM from your mobile and install it. But what if your internal memory is damaged? Or, if you have never changed the ROM, wouldn’t it be more convenient to install it directly from the PC, without taking up internal memory of the device? We will explain how to install a ROM by ADB Sideload, since it is extremely simple:
First of all it will be download ROM package that you want to install on your mobile and store it somewhere accessible on your computer.
Now, connect your device to the computer with USB debugging enabled and, through a command window, executes the instruction “Adb devices”. If the serial number of the terminal appears, everything is correct and you can continue.
Turn off the phone and boot into TWRP recovery mode manually –normally, keeping the Power and Volume buttons less while turning on–, or through the command “Adb reboot recovery”.
Navigating through the volume keys, we must position ourselves above the option “Advanced”, and then select the “ADB Sideload” option.
On the computer, open a command window and type the command “adb sideload [ARCHIVO ROM].zip _ “**, being [ARCHIVO ROM] the path of the downloaded update file. If everything is correct, the installation process will begin.
Once finished, you can restart the device or perform any other operation that you deem convenient.
Install a ROM through recovery
If instead you want resort to the modified recovery already installed on your device, the process is much shorter and simpler. You just have to make sure you have a modified recovery and have the ROM in the internal memory of the device.
Important | In some cases, the ROM installation process itself will completely format the internal memory of our device to carry out a “clean installation”. However, it is also recommended to format the device ourselves through the recovery “wide data / factory reset” options. In any case, it is best to have a full backup on hand so you don’t lose any data.
Download ROM: On the official website of the platform, download the corresponding ROM package for your device, and store it in the internal memory of the Android phone or tablet. It may also be necessary to download the Google Apps package.
Boot the device into recovery mode: To install the ROM, you will need to have a modified recovery like TWRP, which will have been previously installed. To access this menu, the most common is having to keep the Volume Down + buttons on for 5 seconds when the phone is turned off.
Install the ROM: in the recovery, access the “Install” menu. Select the option corresponding to “Install zip from storage / sdcard”, and in the file explorer that will appear, search for and select the ROM package that you downloaded in the first step. Once the installation is complete, it would be time to install the Google Apps.
Thus, You will have already installed the new ROM on your device. Although we have not included it in the procedure, in some cases it is recommended to perform a “Wipe” of the different partitions of the system, such as Caché or Data. However, it will depend on whether the ROM is being installed for the first time, or if it is an incremental update. For this reason, again we recommend that you inform yourself on the official website of the ROM that you intend to install.
Another aspect to take into account is that, although this ROM installation guide will work on the vast majority of current devices, in some it will be necessary to resort to specific tools such as Odin from Samsung or Xiaomi Mi Flash Tool.
