Open the virtual keyboard and type *#7370#. Note that there is a *. I didn't see how all soft spaces were wrong at first. Ha ha.

Specific method

1. Please write down the code of your computer before it becomes soft. (This is very important. The reason why the method provided by those prawns can't solve the problem is to omit this step. )

2. Press *#7370# password: 12345 to make the phone soft (memory card is put before soft).

3. After the computer restarts, you will be asked to choose a country or region (note: this step is the most important). At this point, you must correctly select the country or region corresponding to the code code, and then confirm. At this time, the computer will restart, and then select the language you want and the modification time. At this time, the problem of certificate expiration is really solved. After installing software, the certificate will not expire again. Unless, of course, you need to sign! ! (That is to say, the code you recorded in the first step corresponds to the country or region. If you don't know your password, just turn on the battery on the back cover of your machine and take it off. )

Note: The following are the countries and regions corresponding to the CODE. People who don't know their own code can find it below (the following code is compiled from: generally not good? ):

The first is the Asia-Pacific region:
