How to switch back from wp8. 1 to wp8.0?

First of all, you need to back up all the information on your favorite mobile phone, such as mobile phone contacts, important short messages, Microsoft account information, Nokia account information and so on.

Second, you need to prepare a data cable, the original one is the best! A PC computer, it is recommended to use win8 system! If it is a notebook, pay attention to plug it in! It is recommended that the mobile phone be charged for half an hour before being ready to brush! Finally, prepare a downloaded blockbuster, tea, drinks, coffee and other snacks (in the case of the original charger)!

Third, finally, we need a tool to brush the machine! Nokia Software Updater is a customer-oriented online upgrade tool for mobile phone software just launched by Nokia. The size is about 120M, and Baidu can find it at once!

Now, let's get started!

1. Open the downloaded Nokia software updater, and it will prompt you to connect. Plug in the cable and it will connect automatically. If you can't connect, try several times. If it still doesn't work, refer to step 2.3. Please skip step 2.3 for direct connection!

2. If you can't connect, turn off the phone and click "My device is not started".

3. After clicking, connect the data cable and wait for its automatic connection. During this time, the mobile phone will automatically start and enter an interface with only the words Nokia (let's call it service mode for the time being). After about five or six minutes, the phone will restart and then enter the standby interface! Let him go!

You will find that your mobile phone is magically connected! Needless to say, tick to continue the next step.

5. Update or cancel? Must be updated! Which of these two will come first? Guess, I don't remember)

Start downloading

7. It must be restored after downloading! At this time, the screen of the mobile phone turns red directly, or the Nokia logo, and there is a blue progress bar below, which is synchronized with the computer! This is faster and will be finished in a few minutes.

8. Guess what will happen after recovery?

9. Set the phone after restarting! The computer will return to the fourth interface! If the recovery fails after downloading, don't worry, follow the tips on the computer.

Turn down the volume and turn off the button to enter service mode again! Repeat step 5.6.7! Try this method several times! (Note: After logging in to Microsoft account, there will be a backup option, which can be restored directly! That was backed up when your mobile phone was still in 8.0. If you don't want to use the previous one, you can reset it! If you don't have a backup on your mobile phone, you don't need to read it. )

Finally, look at the mobile phone information. Is it successful to brush back to 8.0?
