officially, it's not supported, but try Tp-link archer C6U v1 (RU)

And what is the difference between them? Maybe I will help to understand and conquer it? I have a router that I can use, I have a ch341 programmer, and I have the time, desire and inspiration. how can i help?

as stated in the other thread, the ID differs ....

try using 52550000 in Support TP-Link Archer C6U v1 - #14 by Borromini

my thoughts on the topic
My first impression is the inux kernel u-boot image. in the u-boot 2048k space is allocated but the kernel of the openwrt takes 2800k. I tried to write it to the computer but the u-boot can not load it, the checksum does not match, have because the u-boot uses less

well, your error looks just like the one in the 1st link ...

but hey, whatever floats your boat.

In this (russian) topic you can download intermediate openwrt image . Then sysupgrade to whatever you want
