Help LG G3 S D722 Stock Firmware

Hello XDA! First I want to say I am not new to rooting but I'm still noob at it.
So here's my problem. I've rooted my LG G3 S D722 (I don't know if it is known as Beat) 3 months ago and I wanted to unroot it today for a software update. The only problem is that I haven't unrooted it correctly. Now I can't root it anymore (or I don't know how). Anyway I wanted to unroot it so I heard a Hard Reset will unroot it but it wasn't like that. After I hard reseted it, a game app which I really like it keeps giving me crashes and I don't know what to do.
I'm thinking that my last solution is to downgrade the software to the stock firmware but I don't how, again. I've searched 12 hours today and I couldn't find anything brilliant and 100% working without breaking the device.
Device : LG G3 S D722
OS: Android
OS version: 5.0.2
ROM: Lollipop
Kernel version: 3.4.0+
Bandbase version: MPSS.DI.2.0.1.c1.15-00044-M8926DAAAANAZM-1
Compiler Number: LRX22G.A1440040099
Software version: V20d-EUR-XX
The point is I want to downgrade it to stock firmware first. If I can't do that I want to root it again (if it is possible) and install a custom ROM, but I would prefer the stock unrooted firmware. Any help?
Thanks in advance!

Hello,
As i understood you don't have Root access,let me tell you some things.
First,If you proceed rooting your mobile,you may be unable to boot your phone.
Second,you should be really careful with what you do.
If you want to proceed,Go to Settings→About Phone and tell me Device Model and what V(Version)of Marshmallow you are.
Greetings.

If you reinstall V30n you aren't going to have root access.
Why not going to a custom ROM?
There is a big variety.
Fulmics it use's LG UX5 (LG G5 software) and with Xceed kernel or Gabriel the phone will have a great performance.
Cyanogenmod aka Lineage OS(The one that I'm using right now)
Great performance,stock android experience and with Gamma kernel you are going to have +more performance and battery life.
But if you don't want to install any ROM then you can flash the pre-rooted V30N and flash Xceed or Gabriel kernel.
P.S:Would you like me to provide you a guide on how to Downgrade your device?
Greetings.

LG G4 V32 Isai Marshmallow

Hello everyone!
I know this phone barely has stock rom files available for download but I want to know if any of you have the marshmallow version LGV3220g to download.
I'm stuck with 5.1 and I can't even update it on OTA because I'm not in Japan...
Or maybe a way to flash a custom Nougat ROM if possible...
Thank you for your response!
