Non at&t rom on at&t device. - General Questions and Answers

Dear ,
I have an unlocked LG G3 D850. It had the at&t and it was causing problems with day to day use. I put twrp, cloudyg3, and rooted. Of course 5.0 is not good, so I want to either revert back to 4.4 or 6.0, but without at&t bloatware.
My question is, can I flash the D855 on the D850? This is not a device specific question. Does at&t change the hardware? Can I flash a non at&t on an at&t device? I would flash the new 6.0 at&t but do not want the bloatware. I would also like to keep it like stock lg, without the CM launcher or that stuff.
Again, this is a general question and not device specific.
Thank you modders!
(I researched and saw no answer to my question anywhere)

If you flash a non verizon rom, you will have issues such as no WiFi and unable to send SMS/MMS and probably others. There are some system files specific to Verizon that must be in the ROM in order to work for Verizon. If you are looking for a rom with bloatware removed, there are plenty in the Verizon Android Development section: http://forum.xda-developers.com/verizon-htc-one-m8/development. CleanRom is a good one to look at. http://forum.xda-developers.com/showthread.php?t=2732877

[Q] How is AT&T with the bootloader locking on this device?

Thinking about switching from Sprint to AT&T and grabbing the G4 when it comes out. Is the G3 easily "mod-able"? I only ask because my brother has the S5 and Samsung has locked that bootloader so tight, there's no way flash custom kernels or modify radios. Is it the same for LG devices?
Thanks

LG you don't have to unlock the boot loader. It's called something (can't place my mind on the name) that bypasses so you can flash custom Roms. If you'd look at the development thread you'll see all the mods/Roms

Beware
AT&T has locked the bootloader on the G3, and likely the G4 as well.
The only reason we on AT&T have custom ROMs is because the code has been "broken" to properly sign custom ROMs and recovery images, which trick the bootloader into thinking that these are "allowed" software.
In essence, it is *as if* the AT&T LG G3 has an unlocked bootloader and development can thus move forward.
It may or may NOT ever happen with the AT&T G4. I don't think we know yet.
I suggest further reading and discussion around here before jumping in on the G4 is custom ROMs are an essential for you.

[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!!!!!

Can you install the Tmo software on an AT&T variant?

Hi All,
Is there any way to essentially put Tmo version of the software on the AT&T LG G5?
I gave my AT&T G5 to a friend, with the unlock code, and they've been fine on Tmo, but I've noticed they are not getting the AT&T updates (Sept 30). In additional I see the Tmo Updates are further ahead than AT&T anyways.
Since they are on Tmo, is there anyway to flash the stock Tmo software on?
Thanks in advance!
I hear its possible but you would run into so many problems such as bootloops and bricks. Its best advised you dont flash t mobile firmware on it. I remember when I had an LG G2 from verizon someone made a stock custom rom the the t mobile variant. That would be your best option, to make a custom rom from the t mobile g5 and flash it to the at&t variant. But since it will be a custom rom, you will get notifications saying you have an ota but they never work

Oreo or rooted Noughat!

Hello all,
Since there wasn't any thread for the general questions here, I opened this one!
I have a note 8 from AT&T with the Android 7.1.1 on it (baseband N950USQS3BRA8) which is sim unlocked so I can use it on T-Mobile.
Using the software update on the phone doesn't give me the recent update, I've already read all threads and I think the only resolution is to do it with odin. On the other hand, I like to have a rooted phone (didn't know samFail came out and always was sorry to be forced to use the stock ROM)
Now my question is which is better for me? what's the gain updating to Oreo? Isn't better to root instead? if so, what instruction to follow to root 7.1.1 on my phone?
Auxilary questions:
I don't have video call anymore (after switching from AT&T to T-Mobile), would it be enabled after root?
I don't know how to change 611 mask number from whatever number AT&T is using to the one from T-Mobile (just curious to know if there is a possible way, maybe using T-Mobile ROM instead of one from AT&T) So is it possible to use another carrier's ROM on my phone?
Please, anyone?!
no answer?!
