Steps to Install LG V20 H990 Stock ROM Firmware (Flash File)
Here in this guide, we will be sharing the easy method to flash the KDZ file on your LG V20 H990 handset by using the LG Flash Tool. Before heading over to the flashing guide below, make sure to follow all the requirements properly. Also, ensure to download all the necessary stuff from the links below.
Pre-Requirements:
As usual, here we’ve shared a couple of necessary pre-requisites to read and follow properly before jumping over to the firmware flashing steps. These pre-requirements are useful to get things ready which will gonna be useful while flashing.
1. Firmware Compatibility
It’s worth mentioning that this particular firmware file that we’ve provided will gonna only work for your LG V20 H990 model. Don’t try flashing the firmware on other LG models to avoid any kind of bricking or stuck in the boot loop issue.
2. Take a Full Backup
Make sure to take a full data backup of your device before doing anything especially firmware flashing. Sometimes flashing a ROM can delete the internal data or even your data can be messed up during flashing. So, to keep things simple and save your data better, just follow this backup method (without root). Alternatively, if you’ve already installed a custom recovery like TWRP on your handset then you can also take a Nandroid Backup by following this method.
3. Maintain Battery Charge
It’s always recommended to check whether your handset is fully charged or not. Even if it’s not fully charged, just make sure to maintain at least a 50%-60% charge level before performing any task to avoid occasional shutdowns or battery juice run out issues.
4. Get Ready a Computer and a USB Cable
Before flashing the firmware file on your handset using a flash tool, you’ll require a PC/Laptop and a USB Data Cable to connect your handset to the PC. Once connected, you can flash the downloaded firmware on your device via the flash tool.
