I am trying to install the snapshot OpenWRT on my TP-Link RE650 v1. I see that people have installed them here but not sure how to achieve it. On my TP-Link TL-WR902AC, I installed by resetting (holding down reset button while powering up) and use TFTP. Only other way I know of is using the Firmware Upgrade of the stock Web Browser but neither of those methods worked for me.
If there is a generic method, I'd appreciate help.
