If you are looking to flash a Stock Firmware on your LG phone or Tablet then here is a Step By Step Beginner’s guide explaining How to Flash/Install Stock LG Firmware kdz files using LGUP flash tool. I will be covering everything with simple Step By Step Guides including the impact or affects of installing a Stock Firmware on your LG Device.

DISCLAIMER:
Manually upgrading a firmware requires patience and a little bit of technical knowledge. Flashing a new Firmware will delete all the data on your LG Phone/Tablet. Before proceeding further you may consider backup your all data. Also understand that YOU are the only person making changes to your phone and I cannot be held responsible for the mistakes done by you.

You must understand that your phone’s data will be erased if you flash a Stock LG Firmware using this method. But not to worry, I have a backup guide for you. If you are on a stock LG Firmware without a custom recovery, or if you want to migrate your data after stock FW installation then follow the below guide:

A NANDROID backup can only take your LG device to a pre captured snapshot but you cannot extract the Contact details or Messages out of the NANDROID Backup. If you want to restore your existing contact, Messages, installed Apps etc. then you should consider the first backup guide.
