Setting up DHCP to debrick the Xiaomi 4A router (OpenWrt)

I’ve left this guide here but it is outdated, for a much easier guide check out this video and debrick tools available here.

This guide shows how to quickly set up a DHCP server and TFTP server to allow us to upload the stock firmware to the Xiaomi 4A router and debrick it. I made the guide quickly due to a request on the OpenWrt forums, someone had asked how I had set up the server, essentially we use the DHCP and TFTP server found here and the 4A firmware found here to repair the 4A router.

This guide inspired our next video, a much larger how-to on the installation of OpenWrt and a much easier method for unbricking the router, you can find that here.

Installing OpenWrt on the HooToo TripMate HT-TM05 via TFTP

The HooToo Tripmate HT-TM05 is another great travel router, like the Ravpower but just without an SD slot. Once again we can use the TFTP method to upload the firmware as I have spoken about in detail here. The installation of OpenWrt is painless and adds a lot of functionality to the HooToo router. My favourite thing to do is have it set up to connect to my VPN then I know wherever I go I have a secure connection. You can also install a USB cellular stick for internet connection on the go!

In the video, I suggest the version from the OpenWrt official page, but in fact, newer versions such as the gl-mt300n found here have been confirmed to work too so keep that in mind. With any version of OpenWrt, it’s best to update it after a fresh install. To do so you can login via SSH:

ssh [email protected]

#Change the IP if you’ve changed it from the default

Now we need to get the latest infomation on our installed software:

opkg update

If you have any issues with the previous step ensure you have an internet connection and that it’s not being firewalled. Next, we issue the upgrade command to install the newer versions:

opkg upgrade

This may take a few minutes to complete, once done it’s not completely necessary but its good practice to reboot:


Your router is now up to date!

The opkg tool used above and be really useful, although you can achieve this in luci from the software tab, you can use opkg to install software as well, it’s very much like apt for ubuntu. To install a software package:

opkg install package-name

#Where package name is the name of the software you wish to install, don’t forget pressing tab can help to auto-complete the name if you don’t know the full name of the package.

Installing RTX Voice on a Non-RTX GPU

RTX Voice is an amazing piece of software that I’ve been regularly using on some of my newer videos, it cleverly removes all those background noises you don’t want to hear like computer fans and keyboard and mouse clicks. By design, it’s only supposed to work on the latest Nvidia graphics cards but people soon figured out this was purely a installer limitation no that the software couldn’t run on older hardware, in fact it runs really well, even on GPU’s that are a few generations old, like my own GTX970!

In this video we show you how to install V0.5.12.6 of RTX Voice and modify it not to check your GPU to see if its “compatible”, the result is we can install and use the software!
