I have two Archer C6 routers one is a v2 and the other v3.2. The v2 is running 22.02.1 but the v3.2 is only supported in SNAPSHOT so I’ve left it running stock.
I’m finding the inconsistencies between the two a bit jarring and I’d like to revert the v2 back to stock until both are supported in stable OpenWrt releases.
I found This topic, but it only talks about 19.07.x and it’s not clear whether I would have to TFTP, or if I can just upload the stock firmware through LUCI.
The instructions there are similar, but they mostly talk about bricked devices and having to use specific firmware versions, some from unofficial links.
My router is very much working and I had hoped to avoid these hoops if it’s actually possible to just upgrade with normal stock firmware via LUCI or UCI commands.
Sorry about your router issues. I have some untested ideas which may be risky. Those steps are acclaimed to have successfully reverted firmware on another TP-Link device. Let me know if you are interested.
