Hi, my phone is flyme 220.127.116.11G. I can see there are only flyme 18.104.22.168Y for download. I try to upgrade but keep getting firmware corrupt. I have tried all the method online. However, still the same result. Is firmware G only be able to upgrade using firmware G only? Please kindly help.
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 22.214.171.124G than go use a “Y” firmware.
