Hello, I have tried updating my N9005 to the latest firmware 5.0 provided on Sammobile. After attempting to flash it via ODIN, the following error occurs:

Retried this step several times, but i have received the same error.
Following a few instructions found on the XDA forums, I tried using PIT file in order to re-partition.
The phone now reboots but will not go past the first boot screen "Samsung Galaxy Note3 N9005".
I tried pulling out the battery and performing a factory reset (along with wiping caches), but the situation is still the same after rebooting the device.
Also I have noticed that upon accessing "recovery mode", a error stating " Failed to mount /system (Invalid argument)" error is displayed.
I'm pretty new at upgrading phones and I've bought this phone recently and was unaware of the consequences of flashing ROMS via Odin.
The initial fw. on the device was 4.4.2 Official Samsung. Is there any way that I can make the phone reboot normally with fw. 4.4.2? Or any other firmware for that matter?

Thanks in advance.
