flashing stock firmware and ROM

Hello Everyone,
I am a new Android User, switched from Blackberry (had to use it for work for many reasons, employer requirement) . i have searched the forum for possible existing answer, could not find any.
i have just bought G2 At&t (D800) version from a previous owner, and it is unlocked by the previous owner. i have already rooted my device with custom recovery, it is Stock ROM 4.2.2 and software version 10o
my main two questions,
Q1 : if i flashed and upgraded to 4.4.2 using either D80220a - KOT49I or recovery friendly D80020c method, will that lock my unlocked phone? (i am using it on tmobile)
Q2 : is there is a significant difference between using D8022a and D80010d boot loader mentioned in kk upgrades candidates.
p.s. Since i am a new android user, but with enough backgrounds to be a developer. i will be starting to work on porting M8 sense 6 and contribute To the LG G2 Community. finally have jumped into the bandwagon hahaha. took me a long time lol ..
cheers

Right now there are many unforseen problems with updating g2 so stay away as long as you can

I don't mind taking risks, my only main concern, will upgrading to stock based kitkat ROM and firmware lock my GSM again and be usable with AT&T ONLY. that is my main concern in the first question.
i know for a fact, that firmware originally is installed by the service provider and is separate from the locking mechanism. Most phones can be unbranded by reflashing a different firmware version. however, i am seeking reassurance from experts to confirm such knowledge
thank you

If you are gonna flash kk I suggest you first downgrade to 10d and use Gary's method or upgrade via tot and then root/install custom recovery but I cannot assure that it will remained unlock as I have not encountered many people who unlock and flash custom roms

I see, i guess i will take the risk and re-update here. but will it matter a lot in term of FUNCTIONALITY. using international (AndroidUser00110001- power user edition) vs garyd9 method, excluding the removal of bloatware.
thanks

Well using androiduser's Rom is nice because of less bloat plus no ciq but I myself would not flash a Rom that changes the model number from d800 to d802 just because if it soft bricks it will be harder to restore via flash tool, which is why I opted and am a current user of Gary's Rom but I debloated it

Cm12 for RAZR HD?

Hello! I have been running CM12 (lollipop 5.0.1) on my XT926 for months now, only updated it once from the original version posted. I decided to update it again because a few things have become wonky; however, it seems the thread no longer exists. AM I GOING CRAZY?!?! Did it ever exist? Did it have to get taken down? Can someone please fill me in? I have absolutely been ENTHRALLED with this ROM and do not want to put something else on here if an updated version of CM12 is floating around here somewhere. I saw Validus is on here, which will serve as my next ROM if this has ceased to exist. Any info is much appreciated!
Thanks!

You probably flashed DHackers version. It was originally linked via his twitter account. Just google dhacker cm12. You'll find the updated ROM

Right on, thanks!

There is no way to downgrade if you're locked. Please search next time, this has been asked and answered a lot.

[Q] downgrade 4.4.2 and install CM12.1

I just want to say thank you in advance for any help that is given, I use these threads a lot and this is the first time I've had to post a thread because I couldn't find an answer already.
Anyway, I have a Samsung S3 SCH-I535 with Verizon running the latest bootloader and Android 4.4.2. I want to install the latest Cyanogenmod and from what I've found online. The only way to do this is to downgrade sense the bootloader is locked. I've downlaoded all the files I need but odin gives me errors because the software is not authorized. I've tried safestrap and have succussfully installed the superliterom ver. 3 but ASOP do not work with safestrap so my only option is to downgrade the bootloader and manually install the latest CM12.1. Please someone help me with this. I've exhausted all my resources and don't know where to go next.

Mobile tech videos has a site with a mail in boot loader downgrade service. Seriously reputable. Takes a couple days and when you get it back your back to 4.1.2 with unlocked boot loader and back to flashing whatever you please

If there is any way around the q-fuse, I haven't heard of it.
442 is stuck with locked bootloader ROMs, so far as I know.

There are a couple companies that offer downgrades and unlocked bootloaders, Mobile Tech Reviews being one of them, and the other being FWIW (I think).
I've heard good things about both, but have never tried them out.

As I noted above I'd be very careful with mobile tech videos as a ton of users have reported a not so great experience with them

[Q] Request Lollipop 5.1.x original from AT&T

Hi, I bought last month a LG G3 D850 from AT&T, I'm from Argentina.
I must say that I'm very disappointed about this phone by the way, the extraction of the FM chip is really anoying.
But I have it, and for a year maybe I must use it.
The problem is that AT&T only update Android if you have a SIM Card from AT&T, and in Argentina AT&T doesn't exist.
I rooted the phone and try Cyanogem (the graphics are really poor and the performance is poorer) and Cloudy G3 (that has A LOT of bugs and problems with the system).
So I ask you, if you can help me, the official AT&T Room of Lollipop. I prefer a lot of AT&T programs (that can be uninstalled) that have a rom that crash every 5 minutes.
I apreciate your help a lot.

You can follow my LG G3 back to stock guide and use the tot method. But there's no lollipop. You'd be stuck with kitkat, as OTA doesn't work. There's no official D850 lollipop tot and probably never will be. You'd have to flash KitKat. And hope OTA might some how work or try manually downloading the OTA after rooting the fresh install of kitkat.

That's a shame.
But anyway, it's secure to come back to kitkat? Or there's a chance of broke the phone without a chance of recoverying it?
Can you put the link of the guide?
Thank you!

There will always be a way. . Just like ever since it first came out. It's just very doubtful that a stock lollipop will come out.
It's not easy to link when mobile but here you go. http://forum.xda-developers.com/showthread.php?p=53452990
Also just googling LG G3 back to stock that guide is the first one.

If you are OK with keeping root and TWRP, there are in fact stock ATT lollipop roms that you can use.
http://forum.xda-developers.com/att-lg-g3/development/rom-lg-d850-20f-lollipop-5-0-1-extras-t3052041 - Stock ATT 5.0.1 ROM
http://forum.xda-developers.com/att-lg-g3/development/rom-20f-stock-rom-debloated-t3059610 - Same stock ATT 5.0.1 ROM but with most ATT apps removed

Thank you very much!!!!!

Bought a used d850, got a few questions

Hi. Bought a used d850, got a few questions.
I'm running lollipop 5.0.1. Is there any way to upgrade to marshmellow without an at&t sim? If no, what's the best way to get a sim if I'm located in canada?
Secondly, how do I go about rooting this thing? How stable is the most stable marshmellow rom that exists for the phone?
Cheers.

CyanogenMod is your best bet for stability now and no you don't need a sim card. Just Google rooting 5.0.1 and once rooted your good to flash CyanogenMod 6.0, you HAVE TO FLASH 6.0 GAAPS with it as well. Google all this and you'll do well, good luck!

Got a bunch of outdated results when I googled "rooting d850 5.0.1", any chance you can link me to an up to date guide?
Also, how stable is the latest cyanogenmod 6.0 when compared to stock android 5.0.1 that I'm running right now? How stable is cyanogenmod compared to lg based roms? What's the most stable lg based rom?
Also, some other questions. Is the d850 missing any features that the other lg g3 variants have? How do I go about making those features work?

Well I'm on an lgg3 850 running CyanogenMod 6.0 it's stable. If you like stock rom then stay with stock. Not sure if you could OTA without a sim card though.

I don't need at&t sim card if im getting cyanogen mod, right? Can i root my 5.0.1 without sim? What lg features are missing on your cyanogenmod? Can you double tap to unlock and double tap to lock?

No there is not sadly. Cheapest way is a go phone sim or H2O sim if you can get ahold of one.
There's no root for MM.

Yes, just won't have the LG phone or any of the LG apps, CyanogenMod has plenty though, YouTube CyanogenMod. No there's no root for MM you'd have to flash back to Lollipop gain root then flash CyanogenMod after you root Lollipop. http://forum.xda-developers.com/showthread.php?t=3249803

Sry if im taking longer to understand this than usual, its my first time.
So if I want LG's Marshmellow, I have to get my hands on an at&t sim and that way I'll never have root access. The other way is to downgrade to kitkat, get root access, then get android 6.0 cyanogenmod/fulmics. Is that a correct understanding?
What features of lg get disabled with cyanogenmod/fulmics? Does the camera work fine? Does the battery life last as long as stock?
Also, another question i couldnt find an answer to - does my d850 have qi wireless charging? Can it get qi wireless charging?
Cheers.

Every single question you have has been answered and discussed here on XDA. Some of these questions I know for a fact have been discussed quite thoroughly in multiple threads. Please do your research.
