Converting a Chinese OnePlus 10 Pro (NE2210) to a Global ROM (NE2213/NE2215) involves using Fastboot tools to flash a payload.bin file, replacing ColorOS with OxygenOS for improved Google services support. This process requires an unlocked bootloader, risks hard-bricking the device, and may cause cellular issues, including the loss of eSIM functionality and potential Widevine L1 downgrades.
