I'm sorry for posting this here but after about almost a day searching the entire internet for a proper solution, I have given in and have created this thread. So recently I was using my phone and all of a sudden it froze, and after pulling out the battery, it hasn't able to boot. Thinking that it was just another random soft brick, I proceeded to TWRP in order to perform factory reset and wipe data in order to flash a new rom. But unfortunately I keep getting the following errors:
E: Unable to mount '/efs'
E: Unable to mount '/cache'
E: Unable to mount '/system'
E: Unable to mount '/data'
E: Unable to mount '/preload'
...done
E: Unable to mount storage
I have tried to format through adb but haven't been able to find a proper command, most require the phone to be at least booting. Please can someone help me out, I don't want to lose my data but also want to be able to use the phone again!

The problem is most likely twrp. Flash a clockworkmod recovery from the official website in .tar format. Flash via odin as you would a rom. You could also flash a stock recovery the same way.

Exactly, not only have I tried to install cwm but also tried to upgrade twrp but even through Odin it fails and I get a NAND Write error. Any ideas on how to over come that?

This looks like my problem, but after trying to wipe in recovery, I can no longer boot into recovery at all. Download mode doesn't work either, no Samsung logo is shown, just a completely white screen.

If odin cant see the phone it's pretty much dead as you need odin to flash a stock rom. If you can get it seen by odin just flash a stock rom.
