I'd get back to forums that cover rooting and ask them for ideas.
http://forums.androidcentral.com/ambassador-guides-tips-how-s/499009-guide-samsung-how-flash-stock-rom-via-odin-new-interface.html for example.
And what a mess that is. Odin may have malware. A pox of that house.
My tab 4 had crashed one day while I was using it, and it restarted itself. Since then, it was stuck in a boot loop (the samsung logo screen), and hard reset in ODIN mode did nothing. It just goes back to a boot loop upon restarting. Apart from sending for a replacement, is there anything I could possibly do to salvage it?
