If your phone can still be turned on to enter the system, go to Baidu to search and download the "Refresh Wizard" and install it on your computer. This software is easy to find. I won't go into details here. Then open the "Refresh Wizard" and use Use the ROOT unlocking function that comes with the software to authorize flashing, and then go to the "Flashing Wizard" to find the system version you want to flash, then download it, then execute one-click flashing, and then wait (backup, flashing)... Flashing Successfully, your phone will automatically restart (the flashing process is in progress) and wait... After the automatic restart, you will find that your phone has been completely transformed this time. The downloaded version must correspond to the corresponding model and firmware code. Otherwise, certain hardware of the mobile phone may not work properly, and in severe cases, the mobile phone may not be able to be turned on. I spent nearly a day visiting forums, checking information, doing experiments, and staying up all night before I came up with the safest, fastest, and simplest solution for flashing my phone. Try it yourself, if the poster succeeds, remember to adopt it
