I want to come back to the OEM firmware for my TP-Link Archer C2 v1 (I want to sell it).
I did not find any procedure for this in the device page :
But the installation method is a bit specific and described with a specific ArcherC2V1_tp_recovery.bin file (for including the U-boot binary extracted from OEM firmware).
It appears then that OEM and OpenWrt firmwares are different on different perpectives (U-boot, etc...), and I don't really feel capable of recovering this device if it would be bricked for some reason ...
My question is simple : what is the best proper way to come back to the OEM firmware ?
Do I simply need to flash the OEM firmware from OpenWrt Luci web interface ?
Or do I need to build a special binary file ?
Or another methodology ?
Currently the device is on OpenWrt 22.03.3 release.
Everything works fine so far on this release.
I read this post but did not really understand its meaning, especially what is 'orig.bin' (is it OEM firmware ?)...
Do I have to do next a 'cat' command after that to merge with another binary (which one ?) ?
I don't get why the OEM firmware would need to be stripped
The mentionned archive forum was going in many directions that it was hard for me to follow them...
Does that mean that if I was trying to flash a 'tplink.bin" from tftp as described before, it should be easy to recover to OpenWrt in case of failure ?
