Hello. I´m asking for help on how to install the stock firmware on this device.
I was successful installing openWRT 18.02 on this device. I had to return to the stock firmware, downloaded it and installed it via MTD write to the firmware partition. The device rebooted and never came back. The only led that lights up is the power. No TFTP has been successful. Can anybody point me in the right direction to recover this device.
This device is a bit similar, so you may like to try the method described here (but of course with the firmware for YOUR device https://openwrt.org/toh/tp-link/cpe510 under Debricking
No, I don't know about this device more than what's in the link, but the TFTP recovery is mentioned on the OpenWrt wiki, so I imagine this suggests that it should work.
Have you tried placing a switch in the middle as the page mentions?
