M8 no OS, "system ui has stopped"

Hi,

I'm having a weird problem with my m8. Last night while it was charging it started to do random "touches." The problem was the charger usb it was connected to, but at the time I didn't know that so I thought maybe wiping dalvik would help. But because it was randomly checking boxes in TWRP it ended up wiping other things too.
I'm not sure what all was wiped, but my nandroid backups that were in the twrp folder and my external sd folders are gone. No big deal I thought, so I got the Android_Revolution_HD-One_M8_43.0 zip that was on it already and reinstalled it via external sd. It worked fine, but when the phone first starts it says "system ui has stopped," and my nav bar and status bar are gone, making the phone pretty much unusable.
While looking at different things, I notice when I boot into recovery it looks like this:

***Software status: Modified***
***UNLOCKED***
M8_UL_CA PVT SHIP S-OFF
CID-11111111
HBOOT-3.19.0.0000
RADIO-1.25.21400021.06G
OpenDSP-v48.2.2-00564-M8974_FO.1211
OS-
eMMC-boot 2048MB
Jan 15 2015,22:51:08.0

It has nothing in the "OS-" space, but I can start it, just not do much without the system ui. In TWRP it says v2.8.5.0

While looking for a solution I read it might be the firmware, so I tried updating that to 4.16.401.10 also by external SD in TWRP, but it fails each time I try.

Any help would be welcome.

Thanks
