Linksys WRT1900ACS V1 - Installation

Hi,

I have a Linksys WRT1900ACS V1, I would like to install the latest version of LEDE, could someone tell how to do this since this router has two partitions and how to install it on the correct partition so I do not overwrite the stock FW just in case I brick the router.

And does this need the latest WiFi drivers for it and if so how do I go around updating these once LEDE is flashed?

Currently the router has the stock FW which is the latest version it can be.

Regards,
Muffin!
