Installation on Tp-Link TL-Wr841N v14

I have a Tp-Link TL-Wr841N ver. 14.0

on the Tp-Link page it shows: (maybe are userful informations for you):
Firmware version: 0.9.1 4.17 v0001.0 Build 200903 Rel.58674n
Hardware Version TLWr841N v14 00000014

Where can i download the correct OpenWRT?
On this page it seems that there is the version until the 13.x version...
And if i Try to put this version it shows "error code 712211"

Please HELP!

It's a 4mb flash device, they're EOL.

This can work?:

Or what of those shoud i take?

You're going to write a 7.5+mb image onto a 4mb flash device ?

So... what image can I use?
Are there someone, also old. It doesn't matter for me...
It is only for a test of OpenWRT UI, after if it works fine and it has the things i would like i will install it on a more powerful device..

Then run it on any x64, from a flash drive.

The image you might be able to boot on the v14, will not allow any additional functionality to be installed, due to insufficient flash space

Ok thanks, i will do like that
