flashing stock firmware and ROM - AT&T LG G2

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.

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

Update to Jelly Bean if Rooted?

Hi all, I have the Verizon GS3 (SCH-I535). When I first got it, I flashed it using this guide - I apparently installed a rom by invisiblek that stripped out a lot of the applications. Well, since I'm a first time smartphone user, I asked in that thread that since my G3 was now rooted if I should accept OTA updates in the future, to which one person told me no. Last night I got a notification that my phone wanted to update to Jelly Bean, so now I'm not sure what to do. I don't accept the update because it will brick my phone, right? And if that's the case, where do I download a rooted version of Jelly Bean for it? (I searched this forum but couldn't really find anything other than people's custom versions, like Slimbean). I'm really confused with all the different rom versions available for the different carriers and models, though I suspect I can only use one for Verizon. Side question too - "rooted" is a modified version of an official OS release, right? It's not a method of installing an OS, it's an actual modified version, right? And if I want Jelly Bean, I have to continue using these modified versions, right?

Jellybean has not been officially released in any capacity to the Verizon GSIII. The update you see is roughly 30mb at the most, it's an incremental update at best from when you purchased the phone. No, it will not brick your phone. If you have a custom recovery then the update will fail. If you do not have a custom recovery then the update will unroot and unlock the bootloader and install successfully. We're months away from a Verizon update to Jellybean.

Download custom roms from the development section. Only flash roms for the Verizon GSIII aka d2vzw. These custom roms are people's different versions of the software available for our phone either officially or in jellybean's case unofficially.

"Rooted" just means the user (you) have the ability to make changes to the system or root of the device that are not possible for stock non-rooted users. Just rooting your device means you gained administrator access to the system but nothing is changed until you install roms or other mods.
There is a truly great post in the development section by DroidStyle that details EVERYTHING you need to ask as a beginner. Here:

Ah, I see, I thought it was JB since there were reports of people in some countries getting the JB update today. Coincidental timing!
Anyways, I went through with the update but it failed.

Ah I see, so if I were to download something that's JB, it's just someone's "fan" version of it? And the JB version that leaked to the international phones today won't work on our Verizon ones?
Thank you for your help!

My pleasure, no worries! I have to much respect for any dev who undertakes developing or porting roms to call it a fan version. It's best to refer to it as "customized" which is what they are: custom versions of what may or may not be available.
Nah, unless there is a leak for the Verizon Jellybean update consider any news you hear/see about GSIII updates as completely useless unless Verizon is mentioned. The international version has completely different hardware inside the phone so any roms meant for that device will not work in the USA GSIII. You also can't actively flash another carrier's roms for this phone, it's not suggested and has the potential to render your device unresponsive.

I seriously need help with this

Okay, so my Android 4.3 AT&T Galaxy S4 is rooted (through Kingo) and the only reason I did it in the first place was to flash CyanogenMod or some stock Android variant. Now I'm being told I can't install a custom recovery on my phone for two reasons. 1) AT&T locked the bootloader 2) I'm running Android 4.3.
Now, I'm considering unrooting my phone but even that's unclear and confusing, and it's hard to find people on these forums who are willing to help with these relatively simple (to the non-newbs, of course) things.
Can I flash a custom recovery? Can I run CyanogenMod or any good ROM? If no, will I be able to, ever? If no, how do I unroot? Would it be wise to just wait for the next update from Samsung or AT&T and install it so I automatically unroot?
Much appreciated.

search for it and read you in.

[Completed] How do I keep my flashed lg g2 I don't care about root?

Okay so I have a question about Lollipop rolling out for LG G2 owners. I have the 32 gb LG g2 rooted and flashed to page plus. I just want to know would it be safe to update to lollipop OTA. would I lose my root or the flash at all?
Hi, thank you for using XDA Assist. Since you're rooted and have a custom rom the Lollipop OTA will fail to install on your device. It won't hurt it if it tries but it will fail. In order for the OTA to work you have to be 100% stock. You can see this on how to that, http://forum.xda-developers.com/showthread.php?t=2432476 but it's probably easiest to just flash the lollipop stock firmware. Back up first though off your device. Also see this for further information, http://forum.xda-developers.com/lg-g2
Also, don't forget to register on XDA to post any questions you have in the threads.
hi sorry I wasn't signed in. I wanted to say that I'm on the stock Rom still. I just have the phone flashed so I could use page plus as a carrier.

[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.

I know it can be done on my GS3 SCH-I535

Hello everyone. This is my first post and I am quite new to the world of smartphone modding. Literally, I have only been learning about this for a few hours. In those few hours I have been able to root my SCH-I535 4.4.2, soft brick it and reflash the stock ROM using odin. So I learn fairly quick and can follow basic instructions. Anyways, thats my intro.
So here is my goal:
1) Update my GS3 SCH-I535 FROM 4.4.2 TO Marshmallow 6.0.x.
So here is what I think I know:
1) The SCH-I535 has a locked bootloader which cannot be unlocked and therefore recovery programs such as TWRP or Clockwork will not work which means I cannot install any ROMS via that method. Correct? This is how I bricked my phone using TWRP.
2) There is a recovery program called Safestrap which CAN be used to install ROMS but these ROMS have to be specifically written to work with Safestrap? Correct?
So here are my questions:
1) Can anybody point me to a tutorial or help me achieve my goal?
2) Where can I find these Safestrap specific ROMS? I have read there is a version of Cyanogen13 for Safestarp. Is this correct?
Thanks in advance.

Correct, your device will never be able to use custom recovery or custom CM/AOSP based ROMs, you're stuck with Safestrap Recovery, modified stock ROMs and Xposed framework if you want to use it in addition to a ROM for more customization.
The safestrap compatible ROMs are stock based and there are no 6.0+ or 5.0+ versions for Verizon S3 that I know of unless I'm missing something.
If you want Lollipop or Marshmallow you'll have to port a stock firmware from one of the other S3 variants or other Samsung devices with similar hardware that has 5.0+ or 6.0+ stock firmware available for it.
Porting is done to convert the firmware from the device it is made for to the device you want to use it on, you'll need a copy of Verizon stock firmware and a copy of the firmware you want to port, then you extract them both and switch the vital stuff from the Verizon firmware over to the firmware you want to port. It's probably too complicated for someone with just a few hours of experience though.

Not to mention there's also no 6.0 stock roms available on any S3 variant.
Additionally OP, it's more than being compatible with safestrap, the roms have to be compatible with the stock kernel because you are unable to change that.
Only way you can get a 6.0 rom is to compile your own AOSP rom, delete the AOSP kernel, and configure that rom to run off of the Samsung kernel. It would be a difficult task, but it has been done before. Nobody has done it yet for this device. And I wouldn't have the slightest idea where to find the information to do that.
Well thanks for the replies. I guess those videos I watched are fake or maybe I just didnt understand them properly. I guess my wife will have to be happy with kitkat..
Now I just need to figure out how to root my SG5 sm-900v. Can someone point me in the right direction? I tried using a guide I found here on XDA but just ended up softbricking my phone. I reflashed the stock though.

It depends on which stock firmware version the S5 has, typically it involves flashing a kernel then using Towelroot to root then install SuperSU then disable Knox then flash a second kernel as mentioned a few posts down in the thread linked below, it has two links you'll need to follow, a few posts below the post with the links mentions the order that you do it in.
androidforums.com/threads/verizon-rooting-samsung-galaxy-s5-sm-g900v.908621
But I think in your case your firmware might be too new and is probably locked down. It's another device that can only use Safestrap and stock based ROMs. That's pretty much what you'll get with any Verizon Samsung device these days, they're all locked from 4.3 and up, its possible to root but no true custom recovery or custom ROMs.

There is a thread linked below that is a discussion of a service provided by a company called MobileTechVideos .com to unlock bootloader for you or unbrick a locked device that has been bricked by flashing TWRP. I don't know if they still offer the service though. They may even do it for the S5, who knows.

Thanks for that post. I checked the links and it requires me to downgrage to 4.4 which I don't want to do. I am on 5.0 and I just want to root it. At this point I dont want to install custom roms or modified stock roms. I'll keep checking for a tutorial for an S5 5.0 root. I tried one here on XDA but I softbricked so I had to reflash the stock.

There isn't a working root for Verizon S5 on 5.0+ that I know of, Samsungs usually require flashing TWRP or CF Auto root but those can't be flashed on locked bootloader devices, only results in softbrick/bootloop or bricked.
