I'm trying to install OpenWRT in a TP-Link TL-WR743ND.

I've downloaded OpenWrt Buildroot and applied the patch available at https://dev.openwrt.org/ticket/10057

The patch applied cleanly.

I expected to see a "TP-LINK TL-WR743ND" target profile to choose inside "make menuconfig" but there was none so I choose "TP-LINK TL-WR741ND v1".

The compiling process produced a "openwrt-ar71xx-generic-tl-wr741nd-v1-squashfs-factory.bin" file. When I tried to upgrade the router firmware via web I got the following error message:

"Error code: 18005
[18:03:38]    Upgrade unsuccessfully because the version of the upgraded file was incorrect. Please check the file name."

Any ideas on how to proceed and/or further debug this issue?

There should be a profile called TP-LINK TL-WR743ND v1 if the patch was applied properly. Check your target/linux/ar71xx/generic/profiles/tp-link.mk for the following entry:

define Profile/TLWR743NDV1 
     75            NAME:=TP-LINK TL-WR743ND v1 
     76            PACKAGES:= 
     77    endef 
     78     
     79    define Profile/TLWR743NDV1/Description 
     80            Package set optimized for the TP-LINK TL-WR743ND v1. 
     81    endef 
     82     
     83    $(eval $(call Profile,TLWR743NDV1))

My "target/linux/ar71xx/generic/profiles/tp-link.mk" was already ok but I had no TL-WR743ND available inside "make menuconfig".

I've just tried running "make distclean; make menuconfig" and I finally got the TL-WR743ND target option inside "make menuconfig". I believe the problem was that I runned "make menuconfig" once before applying the 743 patch.

I will recompile everything again and will report back.

Thanks for your help MBS.

There is a Chinese version of WR-743N router which includes a USB port for 3G dongle.  Does anybody know anything about it?
