ADB wont recognize my G3 - Verizon LG G3

I'm trying to root my Verizon LG G3 on 5.0.1 VS98524B, but now ADB wont recognize my device. Yesterday I was trying to root it using a one click root tool but it would fail (it would say successful, but would not achieve root). today I decided to use the LG flash tool to restore my phone and try again. then I saw that the tool (which claims to support all g3 models on all firmwares above kitkat) did not support VS98524B, but there is another that does, but surprise surprise, adb no longer finds my phone.
update... I have found that ADB on Ubuntu does find and recognize my device, and the security prompt comes up on my device. (does not come up for any window computer)
I have tried; restoring my phone again, installing and reinstalling the drivers, use different computers (2 win 7, one win 10), use different cables, on different ports, change between ptp and mtp, toggling and untoggling usb debugging, restarting my computer, etc.
adb doesn't find the phone while running a root tool, or just doing the adb devices command in cmd....
looked at many threads, and not many (if any) seem to have this problem, and all who did were able to solve using one of the steps I mentioned above....\\
any help?
update... Using Ubuntu adb does recognize my device, and prompts the security pop-up on my phone. (the pop-up does NOT come up for any windows pc)... but I cant figure out how to root the device using Ubuntu)
RESOLVED-- I uninstalled (again) the drivers, and grabbed new updated ones from the LG webpage (which ARE different than the suggested drivers on the root tool page.) then installed the android studio on my computer, and redownloaded adb... not sure which of these steps made the difference, but it worked! now rooted.

You should get a RSA fingerprint window that you have to accept on the G3 when connecting. If you're not receiving it, look in
(C:\Users\*username*\.android)
(C:\android)
(C:\Windows\System32\config\systemprofile\.android)
Delete adbkey and adbkey.pub in those 3 locations. Tap the "Revoke USB Debugging Authorizations" button below USB debugging in developer options. Set connection to internet>ethernet. Restart the adb server in command prompt (adb start-server) and plug your phone in while looking for the RSA fingerprint window to popup on your phone.

I don't think there's been an Internet/Ethernet option since before 12B, or at least before 23C.
@Coltonbyu, choose MTP for your connection type.

I did as you said, but the prompt never appears on my phone, which is odd, as it appeared before the factory reset, but will no longer appear for any windows pc. (it does appear on Ubuntu though)
