I'm sorry, but there is a certain risk to the system after the root obtains permissions. According to the description, if the exception is caused by the deletion of the relevant system program or file. This situation cannot be solved by restoring the factory settings of the phone, and you need to reflash the phone to restore the use of the system.

Fastboot (DOS) can be accessed manually, but it doesn't respond to the computer, or it can't be connected.

Flashing failure solution: Turn on RSD, take off the battery and plug in the phone, press the back button and add the power button (according to your own phone brand, you can search for the method of entering fastboot for this model), and install the battery at the same time. Be careful not to release these three keys for 3 minutes until you connect to the computer 5 and the code corrupt appears on the line brush tool.

You can try it with a card swipe, install the adb driver first, install the MTK driver, and then connect the data cable, open the platform, and write data!
