[Q] S4 rooted with towelroot, factory reset, stuck at odin topic

Hi guys.
My son broke his phone so i got him a 32gb s4, brand new and decided to root it last night before xmas morning. I was successful with towel root, but unsuccessful loading a custom recovery. I decided to give up and restore to factory default. The phone went to reboot and then went to odin screen
product name : sch-i545
current binary : samsung offial
system status : custom
csb - config - lsb : 0x30
write protection: enable
start (224, 1440)
sw rev. check fail : fused: 3,binary:

I have tried to odin back to factory image and it fails with odin 3.7 and 3.9
I am 99% sure it was factory stock....i do remember it was running 4.2.2
At this point, I just want the phone to work again.
Any suggestions?

Rooted with Towelroot - how do I unroot? topic

I have a T-Mobile Note 3, stock 4.4.2 and rooted with TowelRoot.

If I want to unroot, what is the best way of doing so? Since there are different way to root the Note 3, I assume there are different ways to UNROOT it.

PS: When I had a Note 8 that was rooted, I unroot it by using SuperSu (it has the option to do so). However, the root did not get removed. Hence I am asking here.
