Don’t extract the zip file.Ĭustom ROMs do not come with Google’s apps and services pre-installed (with the exception of a few). Later on, you will need to copy the ROM file to the root of your phone’s internal storage. Note that you will need to data wipe your phone in some of the later steps, so it is advisable to do the file transfer later on, after the data wipe - but ensure that your phone can connect to your computer and can receive files, just to be clear that your device drivers are in place. Once you’ve found the ROM you want to install, download the zip file either on your computer or on your phone. If you’re not sure, ask about compatibility in the XDA Forums. Locate the appropriate custom ROM for your exact device. Also, there can be multiple variants of the same device based on carrier, region, etc. Custom ROMs are device-specific so download a ROM that’s made specifically for your device.

Now you have everything ready to install a custom ROM, we can begin the process.

This guide is a general list of instructions and does not take into account any special device instructions. If your ROM of choice comes with its own instructions, please follow them instead of this guide.

Please note again that custom ROM installation instructions can and do vary by device and ROM.
