Dear User,

Run the Modify OEM info in ADB mode and then reflash the phone with the USB Firmware Update. Use a firmware file which is compatible with the newly selected model version and vendor id.

Best regards

Dear User,

Yes, flashing should be supported, but if you want to upgrade the EMUI version it is stongly suggested to do it with OTA updates.

Best Regards,
