How to Unbrick / Flash LG K20 Plus

“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.

  1. bonjour, j’ai le message d’erreur “error: 0x2000, MP26010v_00_1214.kdz file does NOT support “REFURBISH” process”, que doit-je faire ? merci

  2. so i got the firmware in and it still asks for a secure startup password so what password is used? i tired every password i use and now i’m at 13 of 30 so is there a backdoor password? i guess if i make it to 0 the phone is useless and i might as well sell it for parts.

  3. I did extracted the zip file and then the firmware disappeared on me. Just turn off or disable any antivirus you have on your windows and you will be fine.
