Because LG has made some changes in Server settings, You can not use a browser to download the firmware from LG Server directly.

To solve the Blank page issue when trying to download LG firmware:

Solution 1;

Use XDM download manager to download firmware, – Download and install xdm6setup.msi

Once you installed the XDM download manager, Run it.

Copy the firmware download URL., for example, my firmware URL is

http://csmgdl.lgmobile.com/dn/downloader.dev?fileKey=FW44X5H752RJA7SEB7B7QKB/MS34510k_00.kdz

[csmgdl.lgmobile.com] does not work anymore.  Please use our paid service to download firmware. 

Copy the download URL and start a new download job in XDM download manager., Now you should be able to download the firmware for your PHONE.

Another solution:

If you want to use browser to download files from LG server, You need to set “LGE-ActiveDP/0.9” as your browser’s user Agent.,

To change the User-agent settings in Chrome browser, I use User-Agent Switcher plugin.
