How to download official LG firmware for your phone

Downloading the latest LG firmware is easy when you know your device model and serial number. This is a simple trick to download an install all the latest updates for your LG device without waiting for OTA updates.

This trick will work for almost all LG smartphones. But before proceeding further, I want to say that this trick is unofficial. So it might get patched by LG servers. So without waiting any further, let’s start with this simple yet working trick.

Prerequisites:

You need to know about your device model and serial number
A working computer and fast internet
USB drivers
Charge your device for at least 50%

Don’t forget to take a complete backup of your android device

Backup Android Phone Without Root on any device
Backup IMEI and NVRAM on Mediatek Chipset Android Device
If you have TWRP Recovery, Create and Restore Backup using TWRP Recovery

Steps to check official firmware:

1. Take out the battery from your device and copy the serial number. Also copy the device model number as well.

2. Now type the following URL

http://csmg.lgmobile.com:9002/svc/popup/model_check.jsp?model=[model]&esn=[serial_number]

Now change [MODEL] and the [SERIAL NUMBER] with your phones model and serial number

for eg. if your device model number is “VM670” and the serial number is “567408034080388”. Then you would type something like this:

http://csmg.lgmobile.com:9002/svc/popup/model_check.jsp?model=VM670&esn=567408034080388

3. Now press enter and wait for the page to load. Don’t be surprised if the page is blank. In order to view the information, you have to view the page source code.

4. Open the source code of this webpage.

Safari: Right click blank area anywhere on the page, select View Source in the menu.
Internet Explorer: View —>Source

5. Search for the ESN number. You will find this number between <ESN></ESN> tags.

6. Use this ESN number in the following URL

http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=[esn_number]

e.g. If the ESN number is 5699659793570 then the following URL will look something like this?

http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=5699659793570

7. Load the page and see the source code the firmware update link. You will find this link between <SW_URL></SW_URL> tags.

8. Copy the URL into your browser and hit enter. The download should start automatically.
