Thks Tearex for the reply.you need to update with full update package. This little OTA will not install.
As you mentioned "update with full update package"? Can help point out where to download the package. Thanks.
I also tried the update "miui_CAMELLIANGlobal_V12.5.5.0.RKSMIXM_b5dd99bb03_11.0.zip". It has been notified that an update is available through my device. After the installation is complete, it is prompted to reboot the system. I rebooted, and the reboot is stuck.
After stuck on recovery mode fixed, a screen says "Couldn't install MIUI".
I also tried "fw_camellian_miui_CAMELLIANGlobal_V12.5.5.0.RKSMIXM_b5dd99bb03_11.0.zip". A screen says "Can't verify update. It's not allowed to upgrade to unofficial ROM pakage".
I downloaded OTA Update "version 12.5.5.0.RKSMIXM" from
