I brought a meizu note2 two years ago. that was from jd. i never bothered to register a flyme account. now i noticed it cannot upgrade because there is no Meizu account. so i registered an account, still could not login. the error was there is account needed to be logged off first. first i couldn't understand this, then finally figured out that the phone had been registered to another account before. phone reset won't do anything. no wonder the phone came with a lot of malware. now i am worried whether the person did this can do anything to the phone, such as taking private information. i am sure i am not the only person had this problem. really need to be careful when purchasing phones from China.
the original deal was https://www.ozbargain.com.au/node/210042
