This is a thorough guide that will ensure that you back up all of your phone’s information, so be sure to do it so that it’s simple to recover your data when you install new firmware.
Step 2: Downloading the correct ROM
As we’ve said earlier, the best method is to go on the XDA Forums on your particular device and search for a ROM that best fits your needs. Custom ROMs are based on the device; therefore, you should download a ROM designed especially for you.
Different versions for the same model are also based on region, carrier, etc. So keep this in mind. Choose the correct custom ROM for your specific device. If you’re unsure about asking about compatibility, you can do so on the Forums of XDA.
After identifying the ROM you wish to install, you can download the zip file on your computer or phone. It is important to note that you’ll have to wipe your phone’s data during the subsequent procedures, so it’s recommended to complete the file transfer later following the data wipe; however, ensure that your phone is connected to your laptop and accept files, to ensure that the device driver is working. In the future, you’ll be required to copy the ROM files into the root directory of the device’s storage. Do not remove the ZIP file.
Step 3. Downloading GApps as well as Google Apps
Custom ROMs are incompatible with Google’s services and apps already installed (except a handful). Suppose you wish to log in with the credentials of your Google account and access Google’s services such as Sync, Play Store, Gmail, Drive, etc.

Notice: Certain custom ROMs, such as Pixel Experience, come with installed GApps. In these instances, you don’t need to install the GApps file on your own.
Step 4. Booting into TWRP
After you’ve transferred your ROM as well as GApps files into the internal memory of your phone, now is the time to start TWRP to install the files. If you’re not used to the process of booting into Recovery mode, we’ve got instructions on how to enter recovery mode on your phone so that you can follow the steps to start up TWRP. After you’re in TWRP, there are a few steps you’ll need to take care of before installing the ROM that we’ll discuss in the following step.
Step 5. Installing your Custom ROM
After you’ve entered TWRP, It’s a good idea to create an android backup of the entire system before proceeding. This is useful should you encounter an unsuccessful installation. You’ll be able to boot into TWRP and then restore the backup to the state that was previously on your device.
To do that:
- Choose the Backup option from TWRP, and then select Boot System Image Data, Modem, and EFS.
- Swipe to save.
- Wait until it’s finished.
This process will wipe your phone completely. Return to the main menu of TWRP and choose Wipe. After that, Swipe to Factory Reset. Choose Option to Format Data. Select the Format Data option, type in “yes,” and click the tick to reformat your mobile. Noting that formatting the /data partition requires a reboot so that TWRP can recognize your newly-created file system.
Additionally, because your internal memory on the device gets deleted when formatting, you need to transfer the ROM and GApps files to the phone’s storage.
- It is possible to do this via TWRP within the application itself. Navigate towards the Mount section, and then select an Enable MTP option.
- Then, connect your phone and computer, which should be recognized as a storage device. Transfer the gapps and ROM files.
- Afterward, go to your main menu in TWRP and click Install. Please navigate to the folder in which your ROM was saved and the GApps files. Select the ROM, then swipe to install it.
- Go back to the previously used menu and choose to install the GApps file. Also, install it once the installation has been completed, then select Reboot to the system.
If your system isn’t booting after this sequence, you may have to flash/install the ROM. Restart into recovery, after which you flash your GApps file. A second reboot is required in certain situations.
Now you have a custom Android ROM running on your cell phone! It will help if you wait for your phone to boot. The initial booting procedure could take some time, so don’t worry; the phone will start the set-up procedure.
