What are the prerequisites to Install a Custom ROM in your Android?

If you want to change your android a little bit and customize it, installing a ROM can be an option. Not only that, it will add some cool features to your device as well. Just think of amazing UI with premium functioning of the device; yes that is possible with ROM. Now, each ROM is different. And therefore, you need to choose according to your choice.

Well, now after choosing it, you need to install it. If you’re finding it a bit difficult, let me tell you how to install a custom ROM on your Android.

Why install Custom ROM?

One of the best things about Android is the flexibility to utilize custom ROMs. An entirely new version of the Android operating system is contained in a custom ROM. The ability to install, or flash, a ROM has many advantages.

  • You may use a ROM to install the most recent version of Android on your phone if the manufacturer is no longer providing updates for it.
  • You may install a ROM on phones with significantly modified operating systems to get a more “stock” Android-like experience.
  • You may frequently discover ROMs that transfer features from devices made by other manufacturers to yours if you like them.
  • It’s possible to get ROMs that are optimized for speed or power consumption if your phone is sluggish or has a short battery life.
  • De-Googled ROMs are also available, which place a higher priority on maintaining your privacy.

Pre-requisites to Install a Custom ROM

Before you begin, you need to do a little amount of preparation. We’re going to assume for the sake of this guide that you already have everything set up.

  • You require a unique recovery. This little piece of software is used to flash a ROM and generate backups. When you root, a custom recovery is frequently deployed.
  • An unlocked bootloader is required. The majority of phones come with a locked bootloader, which must be unlocked to change the system files. If you haven’t previously unlocked the bootloader, we have instructions for you.
  • Active USB Debugging on your phone, the Developer settings window is where you may enable USB debugging.
  • Turn off security. Before flashing a ROM, it’s a good idea to turn off your security settings, especially if you utilize a fingerprint scanner.
  • Make a data backup. Although a full backup will be made during the flashing procedure, the software Titanium Backup makes it simple to back up only your data. This calls for root.
  • Plug your phone in or charge it. You don’t want your phone to lose power in the middle of flashing a ROM.

Now after this installing your ROM is simple. Follow the simple steps given below.

  • Make a gadget backup.
  • Install drivers for smartphones on PC.
  • Install the platform tools for Android SDK.
  • Enable OEM unlocking, USB debugging, and developer options.
  • Bootloader unlock.
