Unfortunately there is no new firmware or patch tool for this device available. I need WireGuard and maybe mesh network support for that device.
So I decided to compile my own LEDE / Openwrt. Unfortunately there is only a profile for Tl-wa730re v1 and not for v2. The Hardware is slightly different and more similar to Tl-wr741 v4. Unfortunately my device doesn't take the firmware of Tl-wr741 v4 because of HWID Problems.
I need this HWID tool or fitting profile to update it to the right version.
My router always refuses the image with the following message
root@OpenWrt:/tmp# sysupgrade openwrt-ar71xx-tiny-tl-wr741nd-v4-squashfs-sysupgr ade.bin Invalid image, hardware ID mismatch, hw:07300002 image:07410004. Image check 'platform_check_image' failed. root@OpenWrt:/tmp# sysupgrade openwrt-ar71xx-tiny-tl-wr741nd-v4-squashfs-sysupgr ade.bin -F Invalid image type. Image check 'platform_check_image' failed.
