For this smartphone, there are two working ways to get root rights without mandatory flashing. These methods are implemented using different programs and are suitable for different versions, choose the one that is suitable for your device.

We get root rights using Framaroot

This method is verified and 100% runs on the P715 version. If you have a model P710 or P713 with a 10e firmware or later firmware, then this method will most likely not work. On the P710 and P713 with the firmware 10D everything will turn out.

Step 1. Download the Framaroot and install it on your phone. (Unfortunately, all the files found by us are infected with various viruses, so we do not give links to download)

Step 2. Start on the Framaroot smartphone, choose SuperSU, press Gimli, Sam, Frodo, Legolas, Aragorn, Gandalf, Boromir - in general, any character you like if it is available. In my case, a version of the choice of SuperSU + Gandalf was worked. After reporting that the superuser rights are successfully obtained, reboot the smartphone.

P.S. After receiving the root right, this method remains the ability to update LG Optimus L7 II via Wi-Fi. At least, the P715 with the firmware 10c was updated without problems on the firmware 10D. If you still have problems with updates and the phone when you try to update, it gives a message that it cannot do this due to the availability of superuser rights, delete the RCT and RCT.CFG files that are in / Persist..

We get root rights with the help of the Chinese program VROOT

If you have a single version of LG Optimus L7 II, then the method described above may not work. Then use this method that is checked on the P713 model with 10e firmware.

Step 1. Turn on USB debugging. To do this, go to "Settings" -\u003e "Developer Menu" and set the appropriate check mark. If the "Definition menu" is not displayed in the "Settings" item, it means you need to activate it. To do this, go to the "On Device" point and taping to the "Assembly number" item (about 10 times) until the "Developer Menu" is turned on.

Step 2. You download to the PC and install the VROot program, having previously turned off the antivirus on the computer. The installation interface can be displayed by krakoyabram instead of normal letters, but there is nothing terrible.

Step 3. Run to the PC program VROot, connect your smartphone via a cable to a PC (drivers must be installed on the PC). At the same time, "debugging via USB" and "Installation from unknown sources" must be active on the smartphone, and in the USB connection should not stand opposite the MTP and the camera (RTR). VROOT program must define a connected smartphone.

Step 4. Press the green root button (right below) in the Vroot program and expect. After the smartphone restarts itself, it can be turned off from PC - the superuser's right is already present on it.

Step 5. Since the Chinese program, then the SuperSU is Chinese. Replace it into Russian. Download the SuperSU file, throw it on your smartphone and install. Next, we go to "Settings", activate the daws opposite "Allow Super User", "Survival Mode", "Re-registration of applications", "Trust by the system user", after which we go to the "System" subcategory and taping on "Installation in System" -\u003e " Proceed". After rebooting, we remove the "Chinese" and reboot again.

P.S. Make Unroot, that is, delete root rights from the LG Otimus L7 II smartphone you can also use the Vroot program. To do this, you need to start Vroot on the PC, connect the smartphone to the computer and after the program determines the device, click on the gray button (left below).
