Hello. My phone was accidentally locked by a child with a drawing pattern, and I can't ask the child, my phone is a miscellaneous brand, can I restore the factory settings without unlocking? By the way, my phone is a smart Android.

Read it carefully, it will be helpful to users.

1. The general Xiaomi account is registered with a mobile phone number or email number, and the mobile phone number or email number is the Xiaomi account. After registering an account, the system will randomly assign a set of digital ID accounts to the user, so as to avoid the leakage of the user's mobile phone number or email number. The digital account does not need to be remembered, as long as you know the mobile phone number and email number used when registering, just like citizens only need to remember what their name is, and they do not need to remember their ID number.

If you want to know the complete digital account, you can click on Xiaomi on your phone**, you can see it in your personal information, you can also log in to Mi Talk, and you can look at the digital account of Mi Talk.

2. If the Xiaomi account is not registered by the user on the Xiaomi network, but a set of digital ID accounts appear on the mobile phone, in fact, this is also registered by the user himself. When the user uses the Xiaomi mobile phone for the first time, he continuously clicks the next step in the boot step, without careful operation, the system registers the account with the mobile phone card inserted into the mobile phone by default and automatically sets the password.

Users can go to Mi.com or Mi Cloud, click to log in, and then click Forgot Password, and use their mobile phone number or email number to retrieve the password.

3. If the mobile phone number and email number used when registering a Xiaomi account are not used, or the mobile phone is not the user's own and there is a Xiaomi account on the mobile phone, in the above two cases, in the case of forgetting or not knowing the password, if the system of the mobile phone has been updated to MIUI7 and MIUI7 or above, it is impossible to unbind the account, the general flashing is useless, and there will still be a Xiaomi account prompt to enter the password to activate the mobile phone after booting. Because MIUI7 and MIUI7 and above systems are locked in the boot, no one can activate the phone without a password. If this model of mobile phone used to have a MIUI6 system, you can find a way to flash and downgrade to the MIUI6 system, and you can remove the binding of the account, but this is basically difficult.

If this model of mobile phone leaves the factory with the MIUI7 system, then it can only be recommended to go to Xiaomi after-sales service to negotiate and solve it.
