[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!!!!!

Buy New LG G3 (ATT) - Yes or No? Lolllipop bugs?

Howdy folks,
I was going to buy a new ATT LG G3 (D850) to replace an aging Galaxy S3. At $250 it seems a good deal.
Then I read the bad news about how lollipop 5.0 push screwed things up? Should I stay away from this due to Lollipop 5.0 issues?
[I generally don't put custom roms due to lack of time, but if there is one that's bug free/stable I can consider that]
Thanks

I would recommend go for newer phone than older model. Try LG G4 or Samsung phone as your new phone.
As far as lollipop issues in LG G3, I didn't find any issue in my phone, I was very much happy.
Hope this helps.

I just got a new g3 from someone off CL. Definitely worth it. Took me 5 mins to root and put resurrection mm on here. Phone flies and no major bugs that hinder me from loving this phone

While I would recommend a new model (for LG the G4 or V10), the G3 is not a bad model for $250, especially if new. In regards to Lollipop, there are some minor bugs, but no more than I have seen on any other model in my opinion. I have not really noticed any bugs

It depends on what you want to do with your phone. What I mean by that is so you want custom roms? Or at least want to root and install a custom recovery?
Idk about ATT but I'm on Verizon and a lot of there phones have locked bootloader or no way to loki hack and install a custom recovery so that's one reason I still have my g3 after a little over a year and have not bought a g4 [emoji14]
So I say if that's what you want do some research and see what ATT phones can do that.
Also would be using a contract update or just buying it straight out, if it's a contract try to get something newer if you using a contract not the g3 is a great choice I'm running cm 13 and love my g3

Well I have had my verizon G3 since August of 2014 so it's been rooted ever since I got it . But from what I have seen on forms. You should be able to downgrade the software from the latest to older ones then root and install twrp. Unless the latest update blocks that

LG H900 ROMs

Hey, I heard somewhere that if you build a ROM off the stock kernel it would work even if you had a locked bootloader, I am going to try to learn how to make ROMs because it sounds intresting. Just a question.

can't we use flashfire to install ROMs?

Now that we have root I'm sure all these options are being looked at by the devs. Its a waiting game less you have the drive to learn how to become a dev yourself. Me personally I don't have what it takes so I'm just checking the forums daily.

Any luck on cm roms

I doubt CM roms will come out any time soon, if Im not mistaken CM roms need bootloader to be unlocked, which we havent had any yet.
Can anybody confirm if we can flash custom stock roms with flashfire?

T mobile cm-ing away wish we could flash there bootloader

Got a V10 from AT&T today
Hey guys,
We got a V10 from AT&T today in exchange for a G3 that crapped out. I hadn't heard of this phone until I took it out of the box (was expecting a G5). I saw there wasn't a CM release for the H900 and this thread is the most active one I found. I'm a software engineer and have rooted/rom'd several android phones, most recently the G3.
Short story long, I'd like to get CM working/supported on this thing. I saw a guide on stechguide.com for rooting and getting TWRP loaded via lgup/tot method that I'm going to try out. I was also wondering if any of you guys have done this, and if there are any rumors or news for cm support.

If you are on Lollipop you can root using the Tungkick method, but there is no TWRP available for the H900. The bootloader is locked and there is no unlock available for it yet. I wouldn't trust that guide.
If you are on MarshMallow there is no root available yet. Keep an eye out on this forum though, chances are it will break here first.

Hey all! Good news! A 9-year-old bug called the "Dirty Cow" exploit still exists in the Linux/Android kernel can easily grant root on any Android phone!!! See the video below.
http://www.xda-developers.com/9-year...on-of-android/
So there's another bug to exploit for root and even possibly unlocking the bootloader! The bug has been fixed recently in Linux but hasn't been rolled into Android yet. If anyone can get this working on my AT&T LG V10 (running Marshmallow) I'll give a reward of $50! Plus you'll be my hero! Now get crackin!

Have anyone figure it out yet??
Please let me know if you got it

Kriss/anyone.. I assume that nothing has happened with this? There's still interest, no? Come on devs.. Please

There is interest in this. We simply don't have enough devs. We used to, until someone pissed off JCase and he refused to work on the V10.

The key to unlocking their bootloader would be nice

Right, of course. But can I ask for something else that allows the unlock? In other words, can I reword it?
EDIT- I emailed him asking flat out for a way or a contact of his that might be willing to help unlock the bootloader. Let's keep holding our breaths.

D850 sim locked to AT&T - questions about sim unlocking and flashing T-Mo ROM

I recently received an AT&T G3 from a friend and would like to use it on T-Mobile, with T-Mobile's wi-fi calling enabled since I get terrible signal inside my home. The phone is currently sim locked to AT&T. I do have it rooted but that's as far as I've gone.
I have two questions:
1) what is the best way to sim unlock? does anyone recommend a service? I'd like to get this done quickly so that I can begin messing with it on T-Mobile.
2) will I be able to install a stock T-Mo ROM on the device to access T-Mo specific features/apps, and how would I go about doing that? I am familiar with flashing ZIPs and reverting back to stock, but I've never gone cross-carrier before. Does it even matter?

If the phone was fully paid off you can unlock it for free on att website.
No you cannot. You'll run into big issues and or soft brick you can only flash what your model is. You may flash a custom D851 based custom rom if that's available if someone's built it for the D850 but you cannot flash other models stock roms.

Thank you hyelton. Have you heard of any D851 based ROMs with wifi calling enabled that will work on the D850?

New to the ATT V10....no root for MM, I know, but a small question to clarify

Hello
I just received my V10, bought from swappa, and it has 5.1.1 on it. I see that there is no way to root MM, so we have to decide on LP rooted or MM unrooted, right?
If I want to root LP, can you point me to the thread? Also, I shouldn't accept the MM update once I activate the phone, right?

It all depends on what you desire. Some people (like me) can't live without root. Rooting unlocks the full potential and possibilities for the device. Sticking with LP rooted seems like a better choice to me. Also I've seen some people complaining about the battery life on MM as compared to LP.
Here's the link for root:

Thank you affangta. Of course i want root. Who doesn't? My question was more technical than theoretical, like your answer.
My phone forced the upgrade to MM, and thus I'm now stuck like many others; i had no way of stopping the software upgrade right after I activated the phone.
Oh well

Unfortunately, when I bought the phone MM update was already installed in it. Hence, I'm in the same situation as you. What I wouldn't give to go back to LP and root the device
