You can flash from original tp-link. Go to 192.168.0.1 .... admin/admin ....
If you flash with other openwrt and you have checksum error you can use shell command
mtd -r write openwrt.....bin firmware
I will do tftp images later this day too ....
Here are the links for TFTP. Note I did not test any of them. Use at your own risk.
You may broke your router forever or need to soldier serial port to restore.
TP-Link 840 V6.2 link for tftp-recovery is not accessible. Can you plelase have a check once again.
squashfs-sysupgrade image hasn't worked via GUI upgrade menu for me, so I decided to use it for tftp flash by renaming it to tp_recovery.bin ( the file being requestes via tftp) and so I bricked the 840N v6.2 router. Hopefully the tftp image would fix it. The original tp-link firmware doesn't work to be restored via tftp either.

Try this. Sorry but i just do not have currently 6.2 anymore for testing.
I just compiled latest. If this not working better to remove the files.
Let me know ....
squashfs-sysupgrade can not be used for tftp its different size and you need to extra pad 64k.
squashfs-sysupgrade does not work from web interface ? What is the error ?
Thanks, but this tftp-recovery image still does not work. No problems that you can't tests the images. I can test them direclty on my 840 v6.2. I will waste much more time and nerves to compile it, so..
squashfs-sysupgrade was getting the typical user error, which most users are facing. Something like the image is not for this router. I can't test that anymore. Only via tftp now.
Its important to know which version you see at your firmware page. We may have other hardware version for example with more flash or memory. I will try to find some 6.2 around and will test. Please until then i will remove files do not ask for any files because you can break your router.
