For me the issue is a little different. I try to login to my account and it says that 'Account or password incorrect. For non-mainland China phone numbers, please enter 00+country/area code+your phone number.'

I did do this and the result is the same every time.

Then when i try to create a new account with google sign in option for My LeEco. I get a popup that says this phone is already bound to 006422xxxxx63 and that i have to unbind this account by typing the password in. So i type the password in and guess what i get the same popup of 'Account or password incorrect. For non-mainland China phone numbers, please enter 00+country/area code+your phone number.'

Is this a bug with the EUI 5.8 update?

I have tried a factory reset and also data reset from the recovery mode. non of the above work.
Please LeEco fix this issue quickly as i can not use some functions of the phone with out this account logged in.
Please help
