How to Unbrick / Flash LG K20 Plus
Step 1: Installing the necessary programs on our computer
First of all, we’re going to install all the necessary programs on our computer
Lets’ start with LGMobileDriver v4.2 installation
Double click on the setup file to start the installation. You need to install LG USB driver only if it’s not already installed on your computer.
Finish the driver installation by following the InstallShield wizard for LG Mobile Driver.
Now install the LGUP flashing tool by clicking on the setup file.
Complete the LGUP installation but don’t run the program yet.
Step 2: Connecting K20 Plus to PC in Download Mode & installing the necessary drivers
The next step is to boot our K20 Plus in Download Mode
To enter Download Mode –
Turn off the phone
Connect one end of the USB data cable to your K20 Plus
Press the Volume UP key as shown above
Keep the Volume UP button pressed & connect the other end of the USB cable to your PC.
If done correctly, the phone will boot into download mode.
“Download Mode” will flash for few seconds then it’ll change to “Firmware Update” as shown above.
Now, wait for the LG K20 Plus USB Modem & Serial Port driver to install.
We’re expecting LGE AndroidNet USB Modem & LGE AndroidNet Serial Port drivers to install successfully.
Step 3: Loading LGUP with the help of Uppercut & Flashing the Stock Firmware
After the successful driver installation, we would launch LGUP flashing software with the help of Uppercut.
If you would directly run LGUP, it won’t detect the connected phone.
Uppercut aids in the detection of the connected phone in download mode.
Open the Uppercut folder, and run the program by clicking on the exe file.
