When a mobile phone has a problem, such as a hang, a dead battery, a phone lock, or an FRP lock, all of these issues can be resolved by installing or flashing software on the phone. Only a PC can install Flash or applications on mobile devices. To attach to the computer, the device is linked via USB. Furthermore, mobile devices that do not have EDL points, will be unable to connect. That's why we sort the EDL point to put the phone in download mode. To do that we securely open the phone's back panel. After that, we have to remove the battery. Then we have to find the EDL points on the mobile motherboard. We have to connect those two points and then we can connect the mobile to pc to download and install the software. Also, some new smartphones provide the feature by pressing the volume up and down button together while putting the USB cable to enter EDL mode. Also, some allow us to just press the volume up or volume down button to take to the EDL mode.
