Note 3 N9005 Firmware Issue

Evening,

A while ago someone rooted my phone which caused me a lot of issues. I was able to put back on a stock 4.3 n9005 VOD Samsung firmware. I recently found out that Lollipop was out for my specific phone but I knew I couldn't download it without un-rooting the phone. I looked online and followed a tutorial. I went on samfirmware.com got a stock 4.3 firmware and attempted to install it and follow the tutorial. The phone failed to install this and just restarted and worked. I thought if I installed the update of what my firmware was to a kit kat version I thought that might work but it didn't. It got about 9/10 of the way and I got FAIL! (Size).

This has of course completely screwed up the existing firmware and I am unable to get onto my phone. I have attempted to put back its original firmware but I get the following message:

<ID:0/006> NAND Write Start!!
<ID:0/006> aboot.mbn
<ID:0/006> FAIL! (Auth)
<ID:0/006>
<ID:0/006> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)

I am using odin3 v3.09 with the correct firmware e.g. UK n9005 Vodafone. I have tried different USB ports different version of Odin etc etc...

Any ideas would be greatly appreciated
