I’ve powered up both ways and every other way i could think of, with and without resetting. I’ve heard about flashing via uart. But, i havent seen any sort of guide on how to do it. I dont suppose you might be able to point me in that direction?
There are pictures of the board somewhere on the forum of the steps using a GL-AX1800 Flint. Some people have done it with alligator clips but you should really solder pin connectors or wires.
I asked about the power, because technically you should have the cable plugged into the router then plug into the wall. If you have it plugged into the outlet then the device you can short it out and I have observed a spark on both the GL-AX1800 Flint and the GL-AXT1800 Slate AX.
Thank you so much for the time and trouble. I’ll give that a try and break out the soldering iron.
As for the power, i started off just plugging and unplugging from the wall. I didn’t start unplugging from the Flint until after the router LED stopped coming on and i was looking for any reason it might not be powering up. But thanks for that info about the barrel jack
