Firmware is software that is responsible for the correct operation of the phone. Over time, due to careless handling of the phone, defects may appear in the firmware, leading to "glitches" or a complete freeze of the device. In this case, you need to install a custom, "factory" firmware.
Instructions
Step 1
First of all, you need to sync your phone with your computer. In the box in which you bought the phone, along with the charger, there should be a disk with drivers, as well as a date cable with which you can connect the phone to the computer. If these components are missing, you can find the cable at any cell phone store. Make sure the cable fits your phone before purchasing - the connectors must match.
Step 2
Use search engines to download synchronization software and drivers for your phone. Before installing, make sure that the drivers are correct for your phone. The best option would be to download drivers from the phone manufacturer's website. Install drivers and software, then connect your phone to your computer. Make sure the computer "sees" the phone. Copy all personal information from your phone - photos, videos, audio, messages, as well as the phone book. This data must be saved on the computer as it may be lost during the firmware installation.
Step 3
Download flashing software and factory firmware from the web. You can use a search engine to find software, but it is best to download the factory firmware from the cell phone manufacturer's website. Install the software, make sure that the computer "sees" the phone, and perform the operation exactly following the instructions for flashing. During the operation, the phone can be switched on and off several times. In order to avoid switching off the phone, start flashing only with a full battery charge.
