So my contract is coming to an end and I decided to flash a 4.4 based ROM. I didn't do enough research and although I successfully unlocked the bootloader, flashed a custom recovery and flashed the ROM...it wouldn't boot (which I now understand was caused by not having flashed the boot.img from within the ROM).
So anyways, I had wiped this/that/the other in order to try and resolve my above issue.
After much fiddling, I managed to get a Nandroid backup onto my phone (2.17 - restored and booted successfully). I then wanted to use an RUU to return the phone completely to stock. However, no matter what I do, I can't get the RUU to successfully install because my version-main is too new.
Firstly, is what I'm trying to do even possible? The reason why I want to be able to do this is so that if I ever decide to sell the phone on, that I can restore/reset it to as near to complete factory as possible.
Here's my FASTBOOT GETVAR ALL:
