Description

Xiaomi 15 Ultra China ROM to Global ROM service

This remote service converts a Xiaomi 15 Ultra China ROM setup to a Global or Taiwan ROM workflow with Google Play, multiple languages, China app cleanup, and locked bootloader support when available.

Best for China ROM devices that need Google services, language support, call recording notes, and fewer China-only apps.
This is a paid remote flash service, not a public ROM download. OTA behavior can vary by ROM branch, so confirm the target ROM before ordering.
Need bootloader unlock instead? Use the Xiaomi 15 Ultra bootloader unlock service or the broader Xiaomi bootloader unlock without 7 days service.
For other Xiaomi models, see the Global ROM Xiaomi services category.

How the remote Global ROM conversion works
