如题，at first, i selected english as system language and used my CN icloud to recover system data and settings. then the system promptted me to input the password of US app store accout. when i enter system，it was shown some of apps was always waiting to be downloaded. so, i checked the app store accout and it was CN account. no matter i switched it to the US one or the CN one, which didn't work. thanks for your help.
