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 don't know when people will understand that it has nothing to do with sim unlock. I have T-Mobile unlocked sim lg g5 and flashed roms, custom and stock both several times and never had any problem with sim lock stuffs. Just install twrp, root, flash custom rom, there will never hurt anything in your phone.

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.

I read the threads related to LG G5 from buyspry seller. Sadly I cannot revert the order I made on ebay I need to need few important things(to me) as I will be stuck with this Phone. I live in Bangladesh so I definitely cannot use it w/o SIM UNLOCKED.
I have known that If I upgrade or downgrade I will lose SIM UNLOCK.
Also I cannot root (till now) as it requires downgrade.
And I will be stuck with firmware it came in from the seller.
But still , Here are the things I really need to know :
1. If I compromise myself to use that firmware 20i_un (UNLOCKED) forever it comes from seller & do no modifications will the Phone be perfectly fine?
2. Does that awkward firmware gives or will give any OTA update? Cause if it gives and that accidentally gets installed I am screwed with a T-Mobile Locked device.
3. I will use my local GSM SIM , Will I be able to use Portable Hotspot with that ROM? (I couldn't, with my G2 At&t Unlocked stock At&t ROM)
4. Apart from any upgrade/downgrade(ROM flashing) is there any way I might lose UNLOCK???
Please guys, please do help me with these topics. I just recently damaged my LG G2 and lost a phone Xiaomi MI 4 (Mugged) I really am screwed

1) Probably.
2) Probably not.
3) No idea. You'd have to discuss that with your carrier.
4) Probably not, but it's still not clear how they achieved unlock via the ROM so who knows?

You lose unlock if you ever update or do anything to the ROM. Phone is garbage unless you're on Tmobile. Obviously you are going to want to update it eventually because it's assumed that LG will be issuing an official Oreo update.
I bought the device and reverted it to official firmware. With a few (lengthy) calls to Tmobile I eventually got them to white list my device for the Sim unlock app to work. I was first told that it was impossible for them to do because it wasn't a Tmobile device, meaning not purchased through tmobile (not sure how buyspry got them, maybe corporate wholesale or something).
I sent a bunch of photos to them showing the box and other tmobile documentation that came with the phone. They agreed to unlock it and after about a week's wait while tech support was working out the specifics, the app successfully unlocked it.
I am on tmobile but told them I preferred to have it unlocked if necessary for international travel.
So yeah, long story short if you're not on tmobile and have no way to get tmobile to officially unlock it return the device. Complain to eBay that the device had hacked firmware or whatever (which is 100% true) and they will let you return it.

Guide: Returning to stock firmware + re-lock bootloader.
NOTE: following this guide will factory reset your phone so back up your data before hand.
Hi all, after having to do a fair bit of digging around last night in order to return my G7 to stock firmware i
figured i would make a all in one guide to make it a bit easier for people to follow!
First half of this guide is how to re-flash stock firmware:
1. Download LGUP here:Link
1.1 Download additional file we will need later: Link
1.2 Download stock KDZ file: Link
2. Install LGUP, after it has been installed extract the file from step 1.2 and place it here:
"C:\Program Files (x86)\LG Electronics\LGUP\model\common"
You will most likely have to create the common folder first and then place the file "LGUP_Common.dll" inside, this allows the LGUP software to recognise the device.
3. Next power down your device, once it is fully powered off hold the volume up key and insert the USB cable into your device
while continuing to hold volume up, continue to hold until your device enters download mode.
4. Open the LGUP software and drag the KDZ file into the file path section within the software, if your device is not showing
it means you dont have the correct drivers installed or haven't placed the .dll file from step 2 in the correct place.
5. Once the KDZ file is showing in LGUP simply click start and wait for the stock firmware to flash! Once it has completed
your device will reboot!
6. (Optional) download and install LG Bridge and check for any software updates after the flash has completed, OTA updates
can also be checked but in my experience it didnt show any updates where as LG Bridge did.
Second half of this guide will be how to re-lock the bootloader:
1. Download and install Android ADB + Fastboot drivers. The best guide I've found for this can be seen here:Link
2.Navigate to the folder where you have ADB and fastboot installed, usually this folder will be called platform tools.
hold shift and right click inside the folder then select "open powershell window here". Next make sure USB debugging is
enabled in developer settings and then head back to your powershell window and enter the following commands in order:
"adb reboot bootloader"
"fastboot oem lock"
"fastboot reboot"
3. Your phone will reboot and go through the usual first time start up, make sure to enable developer options again and
un-checking "OEM unlock". Your bootloader is now locked again!
If you followed the above steps you should now be back to complete stock! Enjoy
I think it's better to flash stock firmware first to avoid problems when relocking the bootloader, because locking the bootloader just erases /data and /cache, and if you have some modifications like root or twrp it could cause a bootloop.
What I do is first flash stock and then relock the bootloader, with that order you will prevent any problems after relocking.

You can always try! I would probably recommend sticking to the firmware from your carrier though just to be on the safe side. If worst comes to worst you can always use this guide again to re-flash your carrier specific firmware if you find you are having issues! Let me know how you get on if you do try or need any help

I have been reading a bit and apparently there are different modems used between carriers. I currently have an unlocked Tmobile device and was wanting to flash the unlocked firmware...just dont want to risk bricking the phone. The phone works ok with tmobile fw, just wanted to get rid of bloat since I am now using it on ATT prepaid. Can find no info where anyone has done this. I 've flashed several Galaxy phones (to diff f/w)recently and Moto G's a few years back and it worked great.

I know it's possible to flash the boot.img seperate, as I've done that already myself but I'm unsure about flashing a different modem. I imagine the process will be very similar to flashing the boot but I'd need to do some digging and find out exactly! Even if you could there's no guarantee that it would work. I'll do some digging and see what I can find and get back to you!

Assuming LG has made the same decisions for the G7 as they did for the V30, the answer is no.
At least on the V30 series, T-mobile variant can NOT be flashed to anything else because it has different RSA encryption keys from any other V30 phone. This is why back in May when we found the wonderful LG Oreo bootloader unlock exploit, every V30/V30+/V30S on the planet can now be bootloader unlocked and rooted -- EXCEPT for the the T-mobile H932. Because you need Oreo and you need (at least temporarily) fastboot flash commands.
So, all the carrier unlocked US998, European H930 and even the dual SIM H930DS (which have fastboot flash commands) can immediately be bootloader unlocked and rooted. For the others -- like the North American variants AT&T H931, Canadian H933, Verizon VS996, Sprint LS998 -- you first flash the carrier unlocked US998 firmware (aka Frankenstein) over those models to "convert" them to US998 to add back fastboot flash commands. We use dev patched LGUP. Then, after bootloader unlock and root, Sprint and Verizon users often flash back either all or part of their firmware to get back features or LTE bands (Sprint especially). They are still rooted, they still have TWRP. As a result of this, we suddenly now have tons of ROMs and custom kernels are under development.
But T-mobile H932 users are locked out of this development bonanza, because you can't cross flash anything without bricking the phone. I would assume the same for G7? T-mobile must have demanded this, because all the other North American V30 variants share the same RSA encryption keys which make cross flashing possible. If T-mobile demanded it for their V30, seems they would do the same for the next phone also.
Someone with a G7 came in to the V30 Frankenstein thread to ask if it works on G7, but that seems like something that should be discussed in this forum.

Assuming LG has made the same decisions for the G7 as they did for the V30, the answer is no.
At least on the V30 series, T-mobile variant can NOT be flashed to anything else because it has different RSA encryption keys from any other V30 phone. This is why back in May when we found the wonderful LG Oreo bootloader unlock exploit, every V30/V30+/V30S on the planet can now be bootloader unlocked and rooted -- EXCEPT for the the T-mobile H932.

did you try flashing G710EM firmware in the sprint g7? i also have a sprint variant and want to unlock it.
UPDATE: just tried to flash it but lg up doesnt even start flashing the kdz file, it gives "LAF WRITE PROTECTION" and "Cross flash is not supported" messages
luckily phone is working just fine with the original software, i mean it didnt bricked the phone since it didnt even started to flash.
in other post i saw a user that tried flashing tmobile firmware with lg v20 dll and bricked his sprint g7

I am getting same error. I have sprint LG g7. Trying to flash canadian AWM rom.
I followed this tutorial in my LG G7 variant model LM-G710EMW and works. Now, I'm downloading the specific firmware in lg-firmwares.com to install with this method.
I bought my LG G7 in Brazil, with CLARO mobile operator and now I have a LG G7 without bond. Thanks for this tutorial!
With this guide warranty come back?

You should make a post verifying the way you did it and giving proof of this happening. If you do it you will help a lot of people, and maybe it will help other variants to reach root.
How can I solve the "unsecure flashing image to secure flashing device" problem?

model number?
software version?
is it KDZ or TOT firmware?
So what I want to do is switch this phone to straight talk but want the att bloatware off this. If I install unlocked firmware and root the device would that make it unlocked? Like not carrier locked. Straight talk said I can already use a Sim despite it being locked but I wanna unlock it myself.
I don't think att will yet and not sure if they will at all. I'm converting my chapter 13 bankruptcy to a 7 on Tuesday and att bill is rolled into it so the phones will be mine once that is discharged but not sure if they will unlock them right after or if it will take months,that's why I'm asking this. I already reinstalled att firmware on this phone because I tried to install a custom room and messed up due to the bootloader issue of it being v5 I think.
