OnePlus custom ROM — OnePlus phones have a strong custom ROM history, but support still depends on the exact generation and model. A OnePlus 12, 12R, Nord or older numbered model may use different firmware, partition layouts and installation requirements. Check the complete model name and codename before choosing a download.

Important safety reminder
Custom ROM installation can erase personal data and may cause boot failure when the wrong image or instructions are used. Keep a full backup, confirm the exact device codename, read the current maintainer guide and make sure you understand how to restore the original firmware. Do not flash a file simply because its name looks similar to your phone.
Frequently Asked Questions
Can I install a OnePlus 12 ROM on a 12R?
No, unless the official maintainer explicitly states that both models are supported by the same build.
Will unlocking remove my data?
Bootloader unlocking normally performs a data wipe. Back up your information before starting.
Can I return to OxygenOS later?
Often a return path exists, but it depends on the model and firmware state. Save the correct official stock firmware and follow a trusted device-specific restore guide.
