Please help restore stock JellyBean software LG G2 TMobile - G2 Q&A, Help & Troubleshooting

Hello,
I will ask for your forgiveness in advance. I am not a regular on the forum and do not understand all the abbreviations and jargon. I have a T-Mobile LG G2. I really like the phone. That is until I downloaded Kit Kat. Now it sucks. I hate the update for various reasons that aren't important right now.
Can someone please help me locate a thread or post directions with links on how to restore the stock JellyBean software? I called both T-Mobile and LG and they said to back everything up and do a factory reset. Well, apparently the Jelly Bean software has been permanently overwritten. It is still Kit Kat. So that was a waste of hours my time.
I'd be happy going back to stock the day I pulled the phone out of the box. Please help!!!
Thank you in advance.
Neill

As far as I know, it is not necessarily an easy process unless you have done it before. I have done it a few times, and it works, but it is a little "hairy" if you are not technical;

Thanks for the reply. I'll read over the other thread and see if I can give it a shot.

[Q] Unlocked ATT // Unable to Update from 4.2.2 to Current Version

Phone: Samsung S4 I337
Firmware: MDL
Hey guys, first post. A friend of mine referred me to XDA Dev.
I unlocked my phone via one of those "unlock websites" a while back, and just followed whatever directions they gave me. Now my phone works overseas
However I would like to update my phone from 4.2.2 to the current version 4.4.2 (if I'm not mistaken). When i try to do the OTA update, it downloads, and tries to install, but never completes the update and reverts back to 4.2.2. I assume its due to the fact that the phone is unlocked.
Did a few searches, and found a few threads that I feel may be useful, but I don't know where to start.
First question, if I return my S4 to an original firmware, will the phone lose the "unlocked" ability?
Second Question. Where do i even start? It's been a while since i've tried to 'mod' any device, so my problem is the lingo. Just even a laundry list of things I should do would be helpful, and the rest I can google/search my way through. Just need help with the terminology.
Third question, Are there mac friendly programs? or is it all strictly windows/linux
These are the three threads I found.

Unless you want to be stuck with only the ability to use safestrap recovery and roms. Once you update your firmware your bootloader will be locked, permanently! Do yourself a favor and read up as much as you can on this phone and block the OTA update. Be happy it hasn't let you do it successfully. Start in the general section of this forum and read, re-read and read some more.
ok. i'll take your advice on that one.
The real reason i really wanted to update, is so i could make advantage of the SD card slot. because my memory is filling up quickly. What are suggestions that you have?
or should i just seek for another Android phone?

Why do you need to update for that? As far as I know no update has really changed much about SD speed or capacity limit.
If you want to update and keep your bootloader, you can just flash any newer ROM. There's plenty based on stock or near to stock. If you go 4.4, you'll need to flash a modem from 4.4 from the thread in the general section.

Need Help to Flash SPH-L720 Samsung S4 Sprint

I am new to Flashing Android phones and I hope someone can help me through this process. I am technical by nature but like everything else, if you have never done something before, it's always best to consult with those who have as to not brick your phone.
I have a Samsung S4 model number SPH-L720. This was purchased from Freedom Pop so it is technically their own custom ROM on the Sprint network. I later found out that their service is horrible and want to reflash my phone to a standard factory ROM, either a factory Sprint Rom or a Factory Google S4 (Non Carrier Specific) Rom.
The phone currently has Android Version 4.4.2 but I am flexible which version OS is on there.
I am confident with all the experts on this forum, someone can lead me through this process and let me know where to get the ROM's to put on here etc.
The phone already is rooted as it comes from Freedom Pop Rooted already.
Thank you all for your assistance. I will be sure to assist others in the process once I learn it myself.
I'm not a professional, but I might be able to help.... I'll try anyway
You mentioned being fine with returning to the stock ROM. Under normal circumstances that would be pretty complicated because you would need to install using ODIN and re-root afterwards. However, assuming you are running a custom recovery you should be able to install a zip from galaxys4root DOT COM, under the "galaxy s4 rooted stock roms" tab. These ROMs are all stock ROMs that are already rooted and may have a tweak or two. I recommend checking out the ROMs on that site, until you find what your looking for.
The following article should be helpful for installation via custom recovery: highonandroid DOT COM /android-roms/how-to-install-custom-rom-using-twrp-recovery-failproof-method
As I am a newbie on this forum I cannot post links, so please replace DOTCOM with appropriate extensions. Again, I'm not a professional, in fact, this is the first time I've attempted to give any advice yet so I apologize if I am lacking clarity. If I use any terms that don't make a lot of sense to you, feel free to ask any questions and I will attempt to respond in a timely manner.
Not sure how to efficiently help people when I am unable to use links. So I'm sorry if this offends any XDA mods. And I hope that any mods who read my reply will take into account that I am not spamming. I am trying to help.
Any luck?

Still need help with Reverting back to Kitkat on S5

So I posted a thread the other day to try and find help with my S5 I just got, yet no avail. So I'm here again, trying a new one to see if it gets me anywhere. The problem is this, I believe my phone is un-able to revert to Kitkat, because Kitkat was never on it in the first place. It came stock, out of the box with Lollipop. So I'm looking for anyway to get it to Kitkat, even if I have to brick the darn thing by removing the bootloader and everything on the phone to load in stock kitkat. So any advice or questions would be so very helpful. I'm going crazy trying to find a solution! Please help!

Rooting a G2 with the LP firmware still possible.

I love my G2 so much because of the current ROM i am using and for what I use my phone for, I really don't need anything better. The problem is I fool with it so much I am concerned about it wearing out or breaking so I want to buy a backup G2 in case something happens. I imagine a new or used one would problably come with the latest firmware (5.01 or 5.1.1) and I am concerned about being able to root it. It's been so long since I rooted my phone (I think I used ioroot originally) and I haven't kept up with newer root methods so I don't know if they work with the latest firmware or has Verizon closed that door.
Is there still a way to root a G2 VS980 if it comes preinstalled with the latest lollipop updates from Verizon?
I searched through the forums but can't seem to find a definitive answer. Thanks for any advice...
Yes. Please search on LG One Click root. I have rooted my phone LG G2 F320k variant on 5.0.2
Thanks for that info. I saw the OneClick thread, but I was concerned about something they said on the first page about not working on 5.1.1. I didn't read through the whole thread so maybe that problem was resolved and the original post was never updated.

Are there any simple clear tutorials on how to go from JB to Marshmallow?

Currently have TWRP 2.7.0.0 installed and a rooted stock 4.4.2 using the D800.
Does anyone know of any tutorials that can tell me what to do? I'm not new to all this but this G2 has got to be the most discombobulated phone to tinker with that I've come across.
I'm reading that the go to MM I first have to flash KK but then I read that I need to upgrade my TWRP or something to flash KK then there's all this about different bootloaders and etc etc....
I'm just lost. Everything I can find is all from like 2-3 years ago so I don't know what's changed since then, etc.
*sigh*
Can anyone help me? Thanks!

I can help i have same phone , but i see other question in other thread . whats the situation.? right now of the phone. and ill do my best to explain the process never been in jb but i think its the same..
Which specific Marshmallow you're asking about? There is no official LG G2 Marshmallow, but there are several AOSP ROMs. Usually, the process is explained on the ROM developer site or here on this forum in the ROM's announcement.
