Free Flash Drivers

I have Galaxy Note 2 GT-N7100 International Model running Android 4.4.2 KitKat N7100XXUFNL1 firmware. It was working fine until recently it crashed and upon reboot it stuck on Samsung Note II logo.

While flashing stock firmware via Odin I get the following error. I also tried flashing latest TWRP but end up with the same error: NAND Write Start!! and fail

Odin Says:

I hv tried different Odin versions including Odin 3.09, 3.11.1, 3.1.85, 3.4.0. Same error. Tried on Windows 10 an I dont have kies and tried all of my usb ports. Installed latest drivers + I hv never modified this device neither rooted or tinkered ever. Removed battery for each operation. I am afraid to use any PIT files as wrong PIT file may completely brick it.

Moreover, booting into stock recovery gets the following errors:

E:failed to mount /cache (Invalid argument)
E:Cant mount /cache
Installation aborted.
E:failed to mount /cache (invalid argument
E:Cant mount /cache/recovery/log
E:Cant open /cache/recovery/log
E:failed to mount /cache (Invalid argument)
E;Cant mount /cache/recovery/last_log
E:Cant open /cache/recovery/last_log
E:Failed to mount /cache (Invalid argument)
E:Cant mount /cache/recovery/last_install
E:Cant open /cache/recovery/last_install
E:Failed to mount /cache (Invalid argument)

However, I get recovery menus but cannot factory reset or wipe. I cant find a solution fo it. Any help will be appreciated.
