Help flashing OpenWrt on Tp-Link Archer C7 V4

Hello all,

I have tried flashing various files including 18.06 Install and snapshot. I tried the web gui way and also TFTP.

Both ways, on each file, my router soft-bricks and after boot displays a solid power light and a solid Lan1 light (where my cat 5 is plugged in).

I am using a Canadian router but after first bricking it I was able to flash it to stock firmware using the US latest version. I could not flash back to Canadian.

So every time I try a new .bin to attempt to switch to OpenWRT, I produce the soft-brick and then return it back to stock via TFTP.

Can anyone help me successfully flash V4 to OpenWRT.

Thank you kindly.
