Download a custom ROM

Find your preferred ROM for your handset. Download the right one for your handset as many smartphones have several variants. Verify that the ROM you are to download is fully compatible with your smartphone model. The XDA Developers forum is the best place to get a custom ROM.

After finding the custom ROM you want to install, download the .ZIP file. Don’t extract it! Install the corresponding GApps. Then save your GAPPs and the custom ROM in your SD card, flash drive or in internal storage.

Boot into recovery

Boot into recovering using the recovery buttons. On most handsets, the buttons are the Power and Volume Down. Hold them for at least 5 seconds.

Flash ROM

After booting your device into recovery, you will see several options on your screen. Tap ‘Install’. Select the ROM file and then flash the zip.

Clear the cache

After installing the custom ROM, back out and then clear the cache.


This is the most common way of installing a ROM as they are a lot of different ways of doing that. Here is a list of software that is best for the following devices.

  • FlashTool – Sonny
  • Nexus Root Toolkit – Nexus.
