I need to get Archer C7 clear

I got a tplink AC1750 C7v5 that was in a boot loop. I managed to get it out of the loop after a bunch of resets and can now get to and log in to OpenWRT site. Now I would like to get the tplink original factory firmware back on it but I've tried the tftp programs and it won't complete the process. I can get it to attempt to load but it just stops short of loading all the way. The last line in the program always shows 0 blk resent [01/01 04:28:23:359] I'm guessing that means that nothing has been loaded? After the attempt I notice that the router reboots but just not with the factory software restored. Is there any thing else I can try?
