I tried to switch to text mode after getting into graphics mode, but it looks like the background doesent reset propperly, so its all glitched out.

You can fix it by turning off layer 0 with:

POKE $9f29, $21
Or you can just fill the screen with a background color that isn't 0, such as:

COLOR 1,6:CLS

@Greg King answered that in this thread:
Where I had pretty much the same issue: Here is the answer. My issue was even a little bit bigger (reset the palette and stuff), but if you just want to get back to a blank text mode screen that is what works.
10 SCREEN $80
20 POKE $9F25, $80
30 SYS $FF81

Yup, calling the reset kernal routing is another way. Would line 20 actually be needed in that case?

Line 20 is the VERA reset. In my case that was the only way to reset the Palette and all pointers to where they belong (I moved the tilebase etc.).
You can try without the VERA reset. Maybe it is enought in your case.
The above resets the screen to the original setup after startup.
