Are you sure you have a Meizu U20? I didn’t even know it exist. You maybe able to update your firmware through custom methods: https://forum.meizufans.eu/topic/2599/guide-how-to-install-i-international-firmware-on-your-chinese-mainland-meizu
Try method 2 , using DD and root. It maybe time consuming and i would stay on than go use a “Y” firmware.

I don’t think it works for me. As u20 does not support root, it is under Yunos and no root option…
I think I may need to wait until the G firmware support OTA…

Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
