Install OpenWRT on Mikrotik routers - Mikrotik HAP AC2

In this video, we will install OpenWRT on Mikrotik Routers. I used the Mikrotik Hap AC2 as an example. The tutorial can be applied on other models, such as the Mikrotik hEX (RB750Gr3), RB3011 and RB4011 since all Mikrotik routerboards share the same common procedures.
** Installing a third party firmware on a Mikrotik router could void your warranty, lost your license key and even brick the router. Therefore, please watch the video carefully and proceed as your own risk **
The video is long, but there are only 3 main steps:
1 - Backup your RouterOS license key
2 - Netboot the OpenWRT initramfs (Initial Ram Disk) with Mikrotik.
3 - Write the OpenWRT image to NAND permanently

After many hours i finally made it to my Mikrotik RB750 thanks to your tutorial. The hardest part was i used 19.07 soft and i dont work. Then i used 18.06 for initrams and then upgrade to 19.07

Nice video! Thank you! I'm in progress of setting up a DIY WiFi Pineapple on a RB951G2HnD. Hoping to also add external antenna's aswell. Using a USB 5v to 12v converter, allows me to power the unit via it's DC jack, using a laptop or power bank. :)

I want to try this on my rb4011 but openwrt website doesn't show its compatible. In the description of the video it says it does. Where do I get the firmware?

Thank you for the tutorial..the official guide on openWrt is correct but very confusing and general. You were straight forward :)

[pyaethukyaw]

I can't find firmware please give me a link bro

Thank you for your video! It helped me a lot to install OpenWRT on my hAP ac² from the Linux machine. But there were some difficulties. RouterOS ver.7 and later 6.xx versions DO NOT ALLOW to boot other operating systems via TFTP. So, I finally managed to do it by downgrading to an earlier (factory) firmware version 🌞

I couldn't do it without this tutorial. Thank you.

When I try to change the cable from port 1 to port 2 it doesn´t finish flashing openwrt. I never see the message RELEASE received. Any solution?

Is there anyway to dual boot RouterOS and OpenWRT?

[halfeez]

[gaudoitech]

Hi, thanks for the video! I have a doubt Can I install OpenWrt with RouterOS 7.6? factory version is 7.3.1 so in theory it's not possible to downgrade to 6.x.x right?
