Thank you very much! Everything works now
And I am able to OTA update to Version 212 successfully!

@Luksus

Thank you very much for bringing UT to FP3. I have been long awaiting for this.

I have downloaded the latest image and successfully flashed to UT.
As soon as I boot to UT, the OTA update starts to download. I tried a few version and the results are as follows:

Version 207: when the phone started to reboot, it showed the failed message and could never be boot to UT again.

Version 208: when the phone started to reboot, it showed that the OTA update was successful. However, it then kept rebooting to fastboot.

Version 211: same result as Version 208

All these sizes were >500MB. Hope these information can help. Thank you.
