Install OpenWrt on Kingston MLWG3


Looking for anyone that has successfully flashed OpenWrt on the Kingston MLWG3 router. I have found a GitHub resource, but it is old (2016). I am not sure what the best way to proceed is, I have done what I think is the build for the router, but really need some help.

I have been able o connect via JTAG and pulled the details, I can get to the point of TFTP flash, but the file name is not .bin its .ram and I believe from the research - there are 2 kernels ?? SO how do I go about flashing OpenWrt and if I get it wrong?? BRICK.

Looking for experience / knowledge or help of any kind. Thank you.

Maybe the guy who created the factory to OpenWrt via SD card/USB stick images for the MLW221 and the mlwg2 ( can help?
