Back in 2016, LG has launched an entry-level budget segment smartphone called LG X Max. Although the K240F variant is for South America and the K240H variant is for the North America region, the specification is the same. The handset came with a quad-core processor and Android Marshmallow out of the box which becomes quite outdated right now. So, some of the users may find it difficult to continue using the LG X Max due to slow performance. If you’re also one of them, follow the steps to install LG X Max K240F / K240H Stock ROM Firmware (Flash File).

Android is known for its customizations and plenty of users want to customize their Android devices either by flashing a custom firmware or rooting or installing mod files, etc. However, it can possible that your device may get bricked or stuck in the bootloop issue for some unfortunate reasons. If that’s the situation for you, try simply flashing the official stock firmware and you’ll be good to go.

Alternatively, it can also possible that you’re still running the outdated stock firmware on your handset which may starts lagging, stuttering, slow in the performance, battery draining, etc. It’s quite obvious for an older device with outdated software. So, in this scenario, you should also install the Stock ROM to fix multiple common issues. So, before heading over to the guide, let’s take a quick look at the device specs below.

Steps to Install LG X Max K240F / K240H Stock ROM Firmware (Flash File)

Here in this guide, we will be sharing the easy method to flash the KDZ file on your LG X Max K240F / K240H 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 X Max K240F / K240H 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.
