I have LG nitro HD locked to AT&T, I have cyanogenmod ROM. I do have unlock code.
I'm trying to carrier unlock, but when I insert "not accepted" SIM card it doesn't ask for unlock code.
So I try the other method - dial 2945#*930# and nothing happens.
What can I do?

it's the cyanogen rom for sure, I don't think lg would know..
from what I have seen on my phone and other phones if you are using CM7/CM9 or possibly other custom roms that are not based on the stock rom you will not be able to use some of the dialer codes. that could be the reason you are not able to unlock the phone. you will need to flash a stock rom and unlock the phone. then you can go back to your rom and have the phone unlocked

yea thats what i did, thanks
i wish those codes would work on custom roms, like CM
Hi smashcz, did you flash a stock ROM, then you are able to unlock the phone? i have exactly some problem, without unlock, i did my flash.
so first question, there is no other way can unlock after flash a new ROM? second, where did you get "Sotck ROM"? from LG website or from backup? i did backup before flash, could i restore it?
Hey, Guys, hopefully, this is not asked now, but what exactly would happen, if I would flash XT1540 firmware on my XT1541 device? I just found this thread with differences http://forum.xda-developers.com/2015-moto-g/help/variants-moto-g-3rd-gen-t3168594 but the differences looks like just to be the frequencies. My provice uses thre frequences for LTE. 800,1800,2600, Would my XT1541 work "normal" with XT1540 firmware? Or would it brick? If it bricks, why? Are there hardware differences? So much variant for one device is very confusing..
Thanks in advance.

i had the same question btw i also have XT1541 ( Tesco Unlocked verion ) . I rooted it and i am on cm12 . I wanna flash stock rom using adb to intall OTA but i am not sure which one to flash . If i flash XT1541 Tesco Stock rom , i am afraid my device will be carrier locked . There is XT1541 Great Britain Stock rom too. Should it work ? I am currently in India not UK

Hey there friend. Let me tell you something about carrier locking today. IT HAS NOTHING TO DO WITH FIRMWARE OR ROM. Carrier locks are on a completely different partition on your phone, one that is not even easily user accessible so flashing the factory image won't re-lock your phone if it is already unlocked. Hope you understand.

I do not understand why you would want to risk this beautiful device by flashing a firmware not meant for the model you have. I'm sure factory images for XT1541 are available. And if you simply want to take this risk for Marshmallow, don't! Have patience. You will surely get it soon as the rollout will expand gradually.

Is this a Tesco BRANDED device, meaning is a customized version of the device? If so, I would tread very lightly in trying different ROMs, if it is carrier locked or using special radio firmware, it could likely bootloop on any incorrect firmware.
Carrier branded devices are often not the same as the retail versions, and sometimes they are identical... All I am saying is proceed with caution, and although a true brick is unlikely, it is possible.

Yes , its a TESCO branded phone. There is tesco label on the box itself and also the build name in ABOUT PHONE is like this OSPREY_RETGB-TESCO_5.1.1_LPI23.72-47. But its carrier unlocked right now
My question here is if i flash the same XT1541_OSPREY_RETGB-TESCO_5.1.1_LPI23.72-47_cid7_subsidy-TESCOGB_CFC.xml stock rom , will my device be carrier locked or not ?

Once your device is carrier unlocked, flashing a ROM will not carrier lock it again.

I can't say that for certain, it *should* work, but I can't tell you that for certain.
Most likely case if it doesn't work is a bootloop and you reflash stock firmware... You will not relock you device (bootloader or carrier).

Here's what I got. ATT LG G3 running stock Marshmallow D85030p with what I presume is the newest security patch (June 2016)
At this point it's not on a carrier but it's locked by ATT. They kept my number as well.. A number that was mine from previous carriers.
Will I be able to root, install TWRP, and unlock this device to use on a prepaid carrier? Keep in mind this same phone has been flashed, rooted and ran recovery mods and ROMs before. Still in perfect working condition after receiving it's last stock OTA.

First of all what do you mean they kept your number? Did you cancel? Unpaid bill? That would be a deciding factor on how to go about things.
But no root cannot unlock your device
1. If you left AT&T in good standing AT&T will unlock the device for free. Even if you don't have any account.
2. If not then you can get it unlocked for a few dollars from some eBay sellers.
3. What prepaid carrier? If Any provider that runs on AT&Ts network you don't have to get it unlocked, it will work fine with Go Phone, Cricket , H2O and many others that run on AT&Ts network.
But a note if it's no longer on AT&T due to unpaid bill, or on bad terms remember the device may no longer work on any GSM carrier within the USA due to AT&T will blacklist it.

I understand root alone won't unlock it. With all that being said can I still root and flash a recovery method that are permanent? Does MM still not have a reliable root or recovery method?

You would need to downgrade to KitKat to do that. But remember once you downgrade you'll no longer be able to go back to any official firmware Past KitKat without an AT&T SIM card of some sort to ota update it.
Also remember if you get an unlock code you need to be running stock D850 firmware or else you won't be able to enter the unlock code.

Are there any unofficial MM or Lollipop ROMs that are worth looking into? I couldn't care less if it's official honestly. And that last bit you said, you mean if I wanted a phone unlocked I'd have to basically wipe my phone?

If you unlock before you leave behind stock then no you don't have to wipe. Once you install any custom ROM, your only option to unlock at that point is to revert back to stock, which means wiping.

Yes you can, if you are on stock. You will need to get the unlock code from AT&T, be on stock firmware, and have an active SIM card from another carrier (I.e. T-Mobile or of it's MVNOs like MetroPCS). Once you have the unlock code, put in the SIM card, turn on the phone, and you will get the prompts for the code you got. Then you're done.
This is an unlocked T-Mobile G5, but why have a special ROM for unlocked phone? I wonder if I flash other ROMs, I could lose the unlock. Anyone have any problem rooting and install twrp?
Conclusion after a month long discussion:
G5 with H83020i_un ROM is NOT factory unlock. Upgrading or downgrading will result in SIM lock to T-Mobile, period.
Once locked, it can only be unlocked by T-Mobile customers via T-Mobile unlocked app. Some has to go thru T-Mobile customer service and request SIM unlock by adding IMEI to their database.
I bought 6 (New to New other) unlocked H830 and 2 has the hacked ROM H83020i_un and 4 were completely locked to T-Mobile. Yes, those stupid sellers on ebay just keep sending lock phones as unlocked phone! Good luck getting a unlocked one.
No, you cannot install TWRP or root this version.
I ended up returning mine.
You shouldn't lose the unlock by flashing another ROM.
A ROM isn't just about 'locked or unlocked'. The ROM is the operating system. While it will still be Android no matter what you do, different ROMs are modified differently to provide additional features, or more control over the settings or just a slightly different user interface.
This has NOTHING to do with the phone being unlocked for use on any GSM network.
For example some people want to be able to control the CPU processor speed on the phone more. Some ROM's give you that control built into the settings and use customer kernels that allow the CPU to run faster than it does running stock. Other people just like a more simple UI that you get on base Android ROM's (rather than some of the overlays LG puts on)

I can't confirm this personally, but @autoprime mentioned on IRC that everyone who tried flashing other KDZs over this specific firmware lost the SIM unlock.

I don't know when people will understand that it has nothing to do with sim unlock.

It seems that this is not a regular unlock. When I open the T-Mobile app, it says the phone is still locked, but it works anyway.

Did you confirm that by trying the phone with a non T Mobile SIM on a different network? Or did you just let the T Mobile unlocker app tell you it's still locked?
The app isn't the most reliable thing in the world. It's known to say it's not unlocked when it is or that it can't be unlocked when it already is. Etc etc...
Unlocking it manually (through codes, ADB, root, etc....) messes with the unlocker app. But the unlock itself should still be valid.

Maybe it is something to the specific phones people are getting from the ebay seller. They are being sold as new yet are not factory sealed and missing the Tmo sim card. People are claiming Android pay doesn't work and the phone isn't rooted. A new out of the box phone shouldn't have that issue. So something isn't necessarily kosher.
Guys, I have the same version (H83020i_un) and it has April security update and T-Mobile has different version #s on their website. I have checked for update, but nothing came up. So I can't get T-Mobile updates?
The software version H83020i_un is apparently not an official ROM released by T Mobile or LG.
There is a lot of speculation on Slickdeals (a website for coupons and stuff where this eBay deal has been discussed quite a bit) that the unlock was done by flashing a modified ROM. If so that would explain why flashing a new ROM loses the unlock.
Additionally people are saying that Android Pay doesn't work on this phone with that software update, presumably because it's not official firmware. I've never used Android Pay so I have no idea if it works or not.
All in all if you have the H83020i_un software and bought the phone 'new' I think you got conned. It's not new and that seems to be unofficial software.
I spent a lot of time, with help from @autoprime, trying to figure out where the unlock is stored. I was able to dump the partitions from 20i_un using the method here. After I downgraded to 20A and flashed TWRP, I flashed back all the 20i_un partitions (besides recovery, cache, and userdata), and it still wasn't unlocked. So I'm baffled as to how the unlock works.

I see. It will be used as a second device, so it is fine. I flashed the phone with stock T-Mobile H83020a, then got few OTA updates. Now my phone has H83020i, but T-Mobile's page(below) shows an "f" version as the latest. So is the H83020i, the latest update or not? Also would be good if anyone with real T-Mobile unit could chime in.

You cant root a phone to unlock it... just place a non att sim active or not in the phone. If it asks for an unlock code it means it's not unlocked
