Question 7: The student's tablet is locked. If you brush the computer, the contents will be gone. I heard that setting backup password is enough, but how to set it? It is the same reason that the mobile phone is swiped and the computer reloads the operating system. Generally speaking, if it is successful, the mobile phone will run faster, but it does not rule out that the mobile phone will be brushed into bricks because it can't be brushed, files or methods are wrong. Therefore, I suggest that you don't brush easily. You can learn the tutorial of brushing your teeth first, and then make further attempts. If you don't want to learn, you can take it to the repair shop of the mobile phone shop and let others brush it, and it will be successful.
I hope my answer can help you!
Question 8: If the screen of the tablet is locked and the following conditions are met, how can I unlock the Samsung tablet? Suggestion:
1. Remote control and mobile data (or WLAN) has been started.
2. The tablet has been bound with a Samsung account, and you can log in to the Samsung official website-Remote Web page. After logging in with a Samsung account, you can use this function to unlock it. After this operation, the previously set screen lock mode will directly become the default sliding unlock mode.
3. If it is invalid, you forget to back up your PIN password or it does not meet the above requirements, please send the machine to Samsung Service Center, and the after-sales engineer will help you unlock it safely.
Question 9: Apple's tablet computer is played by children, and I don't know how to lock it. I have stopped using it. How can I get 1? If the tablet has escaped from prison, you can download assistant software on the computer, such as 9 1 assistant, pp assistant, AISI assistant, etc. Connect your mobile phone, click File Management and find/private/var/keychains/keychains-in the directory.
2. Tablets without jailbreak can only be reinstalled by connecting to itunes. The method is as follows: download the latest version of itunes from the computer, open it after installation, connect the tablet, close the tablet, and then press the on-off key and the home key at the same time. When you see the white Apple logo, please release the on-off button and keep pressing the home button.
3. When you see a device with dfu status identification on the computer, when prompted by the computer, release the home button, click the OK recovery button on itunes, and click OK recovery in the pop-up selection box (some devices with locked screens cannot be recovered by clicking the recovery button, so it will be more thorough to reinstall and clear the screen password through DFU recovery mode, and it is not easy to make mistakes);
4. Press OK to continue, and then iTunes will pop up a page, prompting that everything will be erased and the resume will be verified to the Apple server. Click the OK button and itunes will automatically download the firmware. When the verification and file extraction are completed, iTunes will automatically reinstall the downloaded firmware version for the device, and then reactivate the tablet after the installation is successful.
