Tried to upgrade the firmware three different ways with no luck:
1. in mobile app, go to advanced->update deco, but app tells me I'm already up to date
2. in web interface, click firmware->upgrade->download from internet, but interface tells me I already have the latest
3. download latest firmware update from tp-link website, unzip bin file, then go to web interface, go to firmware upgrade page, and select the bin file to upload and update. X60 goes through steps of applying the update and rebooting, but after restart the firmware version remains as the old version from 20191216.
I would really like to update the firmware to the latest. Anyone have any luck updating the firmware on the Deco X60?
