I'm not really sure if you mean "flash" by "root" but yes. You can flash any stock ROM as long as your bootloader is locked. Your data will be wiped and you will no longer have root access.
It will be like a brand new phone.
Go check some guides on how to flash back to stock with flashtool.
Use Google for NSIS error fix. I think there are alot of guides aswell.
