Follow any on-screen instructions on your device. Your device will reboot, and the bootloader will be unlocked.

Your device will reboot, and it may take a few minutes to set up. Follow the on-screen instructions to configure your device.

Practical FAQ
What if my device is not compatible with the custom ROM?
If your device isn’t officially supported by the custom ROM, you can try:
- Checking similar devices on the developer’s website

In many cases, a little experimentation and guidance from experienced users can get your device running a custom ROM.

Before starting, make sure to backup everything and be prepared to return to stock if needed.
Common Mistakes and How to Avoid Them
Custom ROMs can be a lot of fun, but they also come with some pitfalls. Here are common mistakes and how to avoid them:
- Skipping the backup: Always backup your data before making any changes. Use Titanium Backup or a similar app to ensure you don’t lose anything important.
