Is there nothing when the phone is refreshed? Do you still have a phone number?

As long as you brush the computer, there is nothing, including the software you are using now. To brush your computer is to format your whole computer and make a new system, so there are no phone numbers, text messages and a series of things, so you should save it or save it first and then brush it. It's best to make a backup of the system before brushing, considering that if the firmware you downloaded is not suitable, you can brush it back. Besides, be careful when brushing.
