[Q] Cant update my LG Optimus G Pro to Kit Kat - LG Optimus G Pro

My phone has Android Jelly Bean installed on my LG Optimus G Pro. I want to upgrade it to Kit Kat ( which is just officially released) but I am unable to find Update Software app on my mobile. I also checked into About Phone -> Software Information but its missing there as well. I am unable to figure out the reason. Is it because my device is rooted and had Custom ROM installed on it? How can I find it out if it has custom ROM installed on it?
Desperately waiting for the help .... Thanks.
P.S. I am attaching the screenshot for the record.

[Q] Is it possible to recover stock ROM on LG Optimus F Pro

I have LG Optimus G Pro E988/F240S, bought a few days ago. After using it for few days, I realized that its factory installed stock ROM was replaced with some custom ROM. The custom ROM is jellybean and I wanted to upgrade my phone to Kit Kat ( official release). But I am unable to find LG Software Update on my phone. I want to restore my phone back to Stock ROM. Can anyone help me with it?
Thank you.

Debloater problems

I've successfully used Debloater 3.90 on both KitKat and Lollipop (ATT Note 4) to stop OTA upgrades. I've tried to use it on Marshmallow but I get the included screenshot (the screenshot is for only one file, not related to OTA, but every effort to block/disable gives the same error message):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Then I tried Debloater 4, but it won't read the phone at all. Update: It won't read ANY of my phones, but knows there are connected.
Anyone have any ideas? And, yes, I know that OTA updates for the ATT Note 4 stop at marshmallow, but I'd still like to get Deboater 3.9 or 4 working properly.

Developer example of LG G8s cannot update

Hello everyone. First of all Im not an expert in mobile software. I recently bought a used LG G8s. The problem is that it is a probably developer version of this phone. There is no SN and the back plate says “not for sale”. The problem is that I cannot update to android 11 or even 10. I've got stock android 9 with security packages from December 2019. I downloaded official ROM from https://lg-firmwares.com/pl/lg-lmg810eaw-firmwares/ and tried to install it by LG UP and LG Bridge, but it not worked. The both of apps detected Phone correctly, but after checking an update the error popped up.

Is there any chance to update the phone with Original Rom?
