Ethernet Isn't Working on Kali Linux(Recovery Mode)

It all started when i was trying to change my display manager from Gnome to KDE, I ran this command to remove Gnome:

sudo apt-get remove gnome-core kali-defaults kali-root-login desktop-base

Then i ran this:

sudo apt-get install kali-defaults kali-root-login desktop-base kde-plasma-desktop

but then my laptop lagged so i had to restart it and then the Grub loading menu has changed a bit and when i booted to Kali i get stuck in a black screen, even the log in menu doesn't appear so I tried to go to recovery mode to download a display manager by using an Ethernet connection but when i tried the previous command again it showed the same thing, it couldn't connect to the internet, one of the good guys here tried to help me (Ciuffy) by telling me what, so i shutdown the laptop, plugged in Ethernet connection,booted to recovery mode again and tried ifconfig but i only get the lo, no eth0 or wlan0 (sorry i couldn't upload an image because i kept getting errors)

and my kali version is 1.0.9

its gonna be hard to reinstall kali from the start so i hope someone can solve this

Thanks in advance
