v13 is based on MediaTek MT7628NN with 64 MB of RAM and 8 MB of FLASH.
And you can find specification in commit message I linked to in this topic.
Sorry!!! My mistake!!! I misunderstood the specs that I saw on another website.
I read on: https://wiki.openwrt.org/toh/tp-link/tl-wr841nd
it says about V13:
Major hardware difference to previous models, now Mediatek based, Wifi not stable, WAN↔LAN Leakage during boot
So there is a known problem with WiFi.
UP
Someone can give me a real feedback on LEDE on this device ?
I've one of these but last comment on WIFI problem got me down ...
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.
I have installed this fw on my 841N V13. Now I want to back to stock tplink fw? Can you tell me how to do this?
Cross-posted here...
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.
Version with error is here: https://downloads.lede-project.org/snapshots/targets/ramips/mt76x8/
Name: tl-wr841n-v13-squashfs-tftp-recovery.bin
Sha256: c41c5cbacb45a31c2cb66f95cb1f4a049f7b7b4850da7a827967b19bd2e4ade7
Release date: Sun Dec 3 20:29:01 2017
Then that's what you need to name the LEDE firmware file.
Hi,
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.
I can give you a example link of video for installation.
Tp-Link 841n v13 upgrade Openwrt (Lede) + Luci GUI
Here is another video link from revert to stock firmware.
DD-WRT TP-LINK TL-WR841N/ND V10 back to stock TP-LINK firmware
My router firmware version is TL-WR841N(EU)_V13_171019.
Thanks in advance.
Hope someone do this for helping every one.
Sorry for my bad English.

It is all there, you just have to read this thread.

I was so excited to see your post but after reading it I became hopeless.
I read all the thread. That's why I posted my previous post.
Installation may be successful but

not sucessful.

Yes, I tried. But my router gone brick after flash this file with “tp_recovery.bin” name.
I flashed LEDE fw after brick to save it. :((
He also post in the TP-LInk forum.

It would be good if Lede allow to install firmware to go back to stock firmware.
LEDE does allow reverting to stock firmware...
Routers do not have a common revert process...it differs by manufacturer.
When all else fails, a serial connection can be used.
There is always a risk in flashing firmware, and issues can happen.
Having a recovery plan is important before flashing.
Until there is a proper way to go back stock firmware I will not test it because I have no serial connection system in here.
If anybody able to revert using TFTP please inform here.
Can you give it a try revert back to stock firmware.
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.
See this OpenWRT thread and the post by "gesucristo"...
Solved - my problem + How to REVERT to STOCK firmware !
Problem:
Would be nice If someone could help me.
I got two TL-WR841N V13 (one for a friend, the other one for me) and flashed openwrt snapshot on both, with the help of these: tutorial, openwrt-docs-luci and yt-video.
One is working really nice, but on the other one I just can not install luci.
If I try to install luci on the second device (on the first device luci is working well):

How I solved the problem + How to revert to STOCK firmware !
1. I did revert to stock firmware : (use at your own risk)
Flash instruction to revert to Stock firmware (same as flashing openwrt/lede, I only had to delete header of original tp link firmware):
Configure PC with static IP 192.168.0.66/24 and tftp server (this yt-video could help) .
Rename "tp_recovery(TL-WR841N(EU)_V13_STRIPPED).bin" (this is my changed version, never use original firmware, when I did I stuck in boot loop 
hopefully I was able to revert)
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.
After it finished flashing, configure PC IP back to automatic.
(changed @braian87b's Lede Flash instruction for my purpose, by the way thanks for your instruction 
)
2. I did flash openwrt/lede again
I used this Flash instruction. I connected over scp with Winscp to 192.168.1.1 with account name "root", I stayed on root folder and started the console. Before I typed in the commands from openwrt-docs-luci. I plugged in my Modem's LAN cable to TL-WR841N WAN for the internet connection.
I think, I only had to stay on root folder, but now I can share how to revert to stock firmware 
I just soft bricked my TL-WR841N V13 three times before I realized that I only had to change a small part
I hope I was able to help you.
Yours sincerely.
Important information:
Guys I do not recommend you to revert to stock firmware, Tp-link TL-WR841N stock firmware is infected with a VPNFilter malware, like all other devices on this list. So if openwrt is working well for you, do NOT revert to stock firmware.

@ralaud after using your given link I am able use openwrt and back to stock rom also. But I have a Dell inspiron N 4010 Laptop that has Intel Centrino N 1000 this wifi device is unable to connect with the router using win 10 and also in ubuntu. so i revert back to stock rom otherwise i wanted to use the openwrt. anyone has any suggestion?
@khandakershahi
It could be a bug, openwrt for our version isn't stable at moment, for example my https server for luci gui just crashed, but on my second device not (due to it has an older snapshot build installed). Just try the next snapshot build (there are daily builds), testing it next week again would be my recommendation.

@ralaud
thank you for suggestion. I already install openwrt to my router but as I previously said my dell laptop won't able to connect to router so I have to leave the router wifi access to no encryption and install nodogsplash. By using nodogsplash username and password now it can connect easily. I don't know how much secure is my access point now. Any advice please.
