Unable to reset or downgrade

[anzi]

I updated from 8.1 to build 10041, had a couple of problems and decided to reset my Surface pro 3 keeping all my files. After resetting I lost the store beta app and all the windows insider feedback apps. So i decided to try and do a full reset. Now I can't do either reset keeping files or full reset. I get a message telling me there was problems resetting the computer, reset using a USB-recovery. I have an 8.1 recovery USB-drive, and when I boot from that, and try to downgrade to 8.1, I get a message telling me there were problems resetting the computer... Anyone have any tips?

The start menu stopped opening for me so I decided to do a factory reset. Now there's an error message and I am unable to do it...

Download the .iso file and run the setup.exe. That works.
