Note: E7000 is a Android4.4.4 system, and the system is hiding the developer option.
1. Because there is no USB mode to connect to the computer to install the driver, so we now go to the E7 mobile phone "application."
2. After entering and then find the following "set" click on it to open the entry, the effect is as follows.
3. Slide up the screen and select "About Device".
4. Find the "build number" and then we click on the finger 7 consecutive times, will prompt "developer mode is enabled" so that the developer option has been successfully opened, we are now back to the superior.
5. Click the "<" icon, and then slide up the screen to see "Developer options."
All right, so our opening options are open, now click on it and then open the developer option. After the USB debugging, we then click to open the E7 USB mode, at this time we have the phone and computer connection can be identified.
