Hello,
I have found firmware for TP-Link WR840N v6 but i can't manage to fit OpenVPN, I tried to build my custom firmware which I can include openvpn but no luck since I don't have enough knowledge to do. Can someone build me firmware? I am willing to give free 1 Month of DO account server of your choice as a thank you reward. Thank you 
For reference it can be found here:
I only need OpenVPN, SSH Access & WiFi. Thanks!
Even if just OpenVPN?
For US$20 or less you can buy a current, supportable router that will likely outperform the TP-Link unit. The GL.iNet units, for example, already have well-supported, OpenWrt installed, including various VPN options.
This is the only router that sells on us others cost $50
I can see you can build only OpenVPN on WR840N v5: https://milankragujevic.com/openvpn-in-4mb-or-how-i-learned-to-stop-worrying-and-love-the-tl-wr840n
But I can't build it to v6 can someone please help me building it? For it requires some memory editing, based on the reference.
https://store.gl-inet.com/pages/shipping-return -- Brazil is listed, assuming you're in Brazil
https://store.gl-inet.com/collections/travel-routers/products/gl-mt300n-v2-mini-smart-router -- US$20
The blogger's approach was to load several large files onto the RAM disk instead of flash. That will not work on a V6 since it only has 32MB of RAM, while the v5 has 64.
Which also means that, even if you could somehow get it all to fit in flash, it will likely crash due to memory (RAM) exhaustion at run time.
32 MB can work for minimal router/AP functions, but may repeatedly “crash”, depending on your hardware and use case
Can I try can you build for me? I cant build it
Excluded pppoe, ipv6, and opkg. Included luci, openvpn-mbedtls, and a few extra things. Might be overstuffed, good luck with that.

On a side note, stop buying TP-Link junk. It stopped being a good brand ever since they revised their logo. They'll just keep pulling scams like this where they cut corners with every new hardware revision of any model that gains traction in the market.
is this wr840n(EU)v6 ?
There is no US v6.
its eu v6 sorry mistype in a rush i thought its us
