Samsung J5 was rooted, did factory reset now I'm lost

[Android Central Question]

Hello,

Like the title says, I have a Samsung J5, I rooted it as soon as I got it maybe a year or so ago.

I never had any issues with it. This morning, however I made a (now in hindsight) bad decision by factory resetting, dont even ask me why I thought I needed to factory reset it, I already did it.

Anyways, I did the factory reset from the phone and it instantly rebooted into TWRP, and here's where I got lost. I don't know what to do from here.

I assumed the phone would just reset itself, but it always reboots in recovery mode.

I thought maybe I had to flash a ROM again (I flashed a custom one and then stock back when I first rooted it, but my memory is terrible and I just have faint memories of it), I looked that up and found I needed Odin, the stock rom I wanted to flash and to reboot into download mode. So I got all I required and I don't think Odin is finding my phone.

My phone just has the blue screen saying downloading... and do not turn off target. Nothing else. and Odin doesn't show anything (I think it's supposed to show the device somewhere? Anyways, I'm super lost and I have no idea what to do.

I mostly just need someone to point me in the right direction, maybe some instructions I can follow or something, I'm not super experienced as you can tell but I can follow basic instructions when I'm not being dumb.

TL;DR: Did factory reset on rooted J5, now it only boots into TWRP, no idea where to go from here, stock rom flash?

First, you have to install the Samsung USB Driver for Windows (into the PC).

Second, look at [Samsung] How to flash Stock ROM via ODIN. And yes, you want to flash the stock ROM.

This is assuming that you never made a system backup in TWRP. If you did, just restore it. And restore any data backup at the same time.
