Unbranding One mini 2

Have successfull unlocked One mini2 from A1 Vodafone with XTC2Clip
After that i have changed CID (SuperCID and HTC__001) and flashed unbrandet zip File from Support (OP8BIMG 2.18.401.3)
Phone now unbrandet. But OTA Update not work, it says that new firmware 2.19.401.1 is available but i cant install it.
Message: On your phone is an unofficial systemsoftware…

How can i make unbrandet with worked OTA Update? I think i need RUU and not zip Files
