Dude. Amazing work. Will test Monday when I'm back. What commit on your
git?
Latest in 840N-v5 branch, still gotta make some adjustments tomorrow.
@robimarko, I would love a copy to test as well, I have a 840N-v5 right next to me, just waiting to install LEDE on it 
Ok.
Here is the sysupgrade image:
https://drive.google.com/file/d/0B1VOQQ-_EIXKNWU0SFBPVnBSODA/view?usp=sharing
Just flash it through the firmware upgrade in TP-Link web UI.
Wait until the green LED stops flashing and the device should be ready for use.
NOTE:There is no LUCI web interface in the image since device has only 4MB of flash and therefore it does not fit with LUCI,so you can manage your router through SSH.
Also,on my router TFTP recovery is broken since TP-Link reused bootloader code for v4 and that does not take int account only 4 MB of flash and bricks the device.
So do not use TFTP Recovery or you will have to rewrite SPI flash like I had to 3 times.

Confirmed, issues with TFTP recovery are due to reuse of v4 bootloader.
I have compiled new one that correctly flashes over TFTP.
If you want to test it contact me.
Absolutely, ready to test, thank you very much! Do you know if the adjustments you made to the wireless make it more stable? in V4, it was terribly unstable. Constant disconnects render it virtually unusable.
Like so.

That is only difference.
I will send you sysupgrade image with unlocked boot partition.
From it you can flash new bootloader.
Any bugs found or I can open PR?
nice one...
I can test monday morning since i'm out of the office until then. quite sure it will work well! I'll just git clone your 840 branch and flash the TFTP, correct?
You gotta build if you want to clone my branch.
You can use the provided images,and do not use TFTP because you will have bricked board.
Just flash sysupgrade image through stock web ui.
In order to use TFTP you need to have image with unlocked bootloader partition and then flash new bootloader
Ok built the commit you made 2 days ago from 840v5 branch. (sysupgrade)
Código de Error: 4503
El archivo cargado no fue aceptado por el dispositivo.
The loaded file was not accepted by the device.
Versión del Firmware:0.9.1 3.16 v01e4.0 Build 170503 Rel.71903n
Versión del Hardware:TL-WR840N v5 00000005
This directly from the WebGUI of 840v5
I tried your Google Drive Image - it did not flash.
I checked out
commit 4c74f19a858ea6b93a0f92768615b5e47d6a7193
From your 840v5 branch. and built
lede-ramips-mt76x8-tl-wr840n-v5-squashfs-sysupgrade.bin - it didnt flash either. same error - 4503
Weird, that means that firmware version on your router was probably different.
This worked on EU firmware, what version is yours?
UN or other?
If so It may be needed to append regional metadata for the router to accept it.
Do you maybe USB to serial cable so that you can pick up an actual error message?
ok done. 840V5 GUI FLASH:
[ rsl_sys_updateFirmware ] 2126: Firmware version check failed
[ rdp_updateFirmware ] 345: perror:4503
Ok,
what version of firmware and which region are you running?
Firmware:0.9.1 3.16 v01e4.0 Build 170503 Rel.71903n
It reads as 840n Ver 5.0 (ES)
Can you try downgrading to oldest firmware available?
If that does not help I will look into adding regional metadata tommorow
Tried flashing TL-WR840N(EU)_V5_170608 onto this ES via TFTP - Apparently bricked the device. I can still flash via TFTP, but now it just flashed a green led after flashing the image. TL-WR840N(ES) does not have an image to download and flash.
