Until (if at all) TP-Link fixes described problem, the only way to flash
LEDE image in these devices is to use tftp recovery mode in U-Boot:
Configure PC with static IP 192.168.0.66/24 and tftp server.
Rename "lede-ramips-mt7628-tl-wr84...-squashfs-tftp-recovery.bin"
to "tp_recovery.bin" and place it in tftp server directory.
Connect PC with one of LAN ports, press the reset button, power up
the router and keep button pressed for around 6-7 seconds, until
device starts downloading the file.
Router will download file from server, write it to flash and reboot.
To access U-Boot CLI, keep pressed "4" key during boot.
I just installed the latest snapshot onto an WR841N v13, and the wireless is working fine for me. Installation is like other new TP-LINK models where you use a tftp server. Frankly, the flashing process using the tftp server is a lot faster than I remember the older process of using the default TP-LINK firmware to upload LEDE/OpenWRT.
Latest snapshot build can't be installed via TFTP. Maybe it's too big? Unsure how to see error logs during TFTP flash. TFTP server sees repeated RRQ for tp_recovery.bin, eventually the device resets, but will reboot back to stock TP-Link firmware.
Can any one do an installation on TL-WR841N V13 and record it and upload it to YouTube and also the reverting process to the original stock firmware and show us from what distance the android or laptop able to connect as I know there is a Wi-Fi issue.
I am eagerly waiting to test it in my router but I am afraid if it not work properly than what should I do.
Yes, I have renamed tp_recovery.bin, with the right permissions, as I have done for all the other routers I TFTP successfully. Any other ideas? Could you try to verify with the latest build? I provided the details in this post to be clear about what version I am using.
