1. You Will Likely Need Root Access
You may need to root your phone or tablet before getting started. This means you need to have access to the root level of your operating system, otherwise known as having administrator privileges. This is something you would generally achieve on a PC by merely entering the password of the user with primary control. On Android, things are a bit more locked down than that, despite it being open source, due to it being a mobile platform. Manufacturers and carriers generally don’t want you to tamper with the underpinnings of your phone, so you’re largely on your own with finding out how. This will typically consist of searching “how to root
2. You Will Need To Wipe Your Device
Installing a custom ROM requires you to wipe your device. This means that a successful attempt will result in your erasing all of the data from your phone or tablet. On the other hand, a botched attempt may brick the device to the point that it’s unusable. Be careful, and be sure to back up your data before getting started. Here’s a guide on how to do so.
3. Research, Research, Research
The XDA Developers forum is a great place to keep an eye on. In general, new ROMs, how-to guides, and useful resources pop up here for people interested in tinkering with their devices. There is even an in-depth wiki that can guide you through the process of flashing various pieces of software to your device. Not familiar with the term ‘flashing’? The wiki will get you up to speed on the terminology as well.
4. Pick The Right ROM For You And Your Device
One thing that will make the process much easier for you is picking a custom ROM to install. These tend to come with in-depth tutorials that explain how to get them up and running on your device. A few of the more popular or current options include LineageOS, AOKP, Paranoid Android, OmniROM, and MIUI.
Final Thoughts
There are some things you need to remember when installing a custom ROM. These are often developed by enthusiasts, and while they may have the best of intentions, they lack the resources to ensure flawless compatibility with every device out there. Even if you get one up and running on your device just fine, you might find that there’s something wrong with the camera or the GPS can no longer lock your position. Many people who install a custom ROM end up switching back for one reason or another, so I cannot stress this enough – do your research beforehand. Sometimes the right combination of launchers and apps can provide the same functionality with substantially less risk, time, and effort.
