Guys, I need some help -- can't copy files to sdcard or internal memory after TWRP fo

Long story short -- I'm selling my Note 4 so I wiped/formatted EVERYTHING (used "format data" option in TWRP which required me to type "yes"). After that happened I found I didn't have an OS installed. Ok, no big deal right? I'll mount my sdcard and copy the stock firmware over than flash with TWRP.

WRONG. Every time I try to copy a file to either the sd card or the internal storage, I get the following error message:

Quote:

"Cannot copy Trltetmo_N910TUVU1ANJ7_Stock_Deodexed.zip Its file size is larger than the device limit."

Wtf? In file explore it says that the SD card has 29.7GB free space available. And internal storage has 24.1GB. Obviously something is not right here.

Is it possible that TWRP didn't format things correctly? I just want to know how to fix this so I can get the stock firmware back on this bad boy and get it sold. I have been out of the android scene for awhile so any and all help is greatly appreciated.

Also, not sure if it's worth noting but when I mount my Note 4 in windows with TWRP both the internal storage and sd card have like no file structure or files whatsoever. Completely empty. Also interesting is every time I reboot with TWRP, it asks if I want to install supersu or whatever to root the phone. I say "yes" but each time I reboot after that it asks me the same thing like it didn't actually do anything.
