After kernel upgrade I can't get the open source radeon driver to work

Hey! I've always wanted to check out what goodies the new kernels bring so I finally decided to give it a shot. Did everything the same way Head_on_a_Stick described in his guide (https://forums.bunsenlabs.org/viewtopic.php?id=1257) but after rebooting my radeon driver just spits out few errors that state it couldnt load required files (log: http://pastebin.com/Kudf5iY9). I've tried manually downloading the files it couldnt load and replace it but no luck. I'm out of ideas because it's the first time I had to switch to open source ones since fglrx went all crazy after the kernel upgrade so I decided to stick to the solution that actually works at least decently. Any ideas how to fix it? Thanks in advance!

//EDIT
Forgot to mention what kernel I'm running: 4.3.0-0.bpo.1-amd64. Switched from 3.16.something.

I assume you are aware you can boot the old kernel, and get your graphics back?

My humble apologies onemadriven, there was a critical error in my guide.

The 3.16 kernel can be selected from the "Advanced Options" sub-menu in the GRUB bootloader screen.

You need to add the "contrib" & "non-free" components to the Debian jessie-backports line in the file at /etc/apt/sources.list so that it looks like this:

deb http://httpredir.debian.org/debian jessie-backports main contrib non-free

Then update the package database and install the firmware:

sudo apt update
sudo apt install firmware-linux-nonfree/jessie-backports

You should then be able to reboot into the 4.3 kernel.
