Project description:
"I have a OnePlus 12 running the stock Chinese firmware and I need it fully converted to the global/US edition on the latest stable OxygenOS build. I’ve never flashed a phone before, so I’ll rely on you for both the process and the peace of mind that nothing gets bricked along the way.

The job covers everything from choosing or preparing the correct, signed global ROM through to a successful flash, first boot, and verification that the handset now behaves exactly like a factory-sealed global model (Google services, OTA updates, 5G/VoLTE bands, etc.). You’re free to pick whatever flashing method you trust—be it OnePlus’ official tools, MSMDownload, fastboot, or reputable third-party utilities—as long as it’s proven safe for the OnePlus 12.

Please include:

• The exact ROM package you’ll use and where it’s sourced
• A live or recorded walkthrough (screenshare or video) that lets me follow each step
• Post-flash checks confirming the phone is on the latest stable OxygenOS global build and passes basic SafetyNet / Play Protect integrity

Once those points are met, the project is done." (client-provided description)
