so im pretty new at this and am learning, so i used this guide ,
http://forum.xda-developers.com/galaxy-s2/general/how-to-root-stock-recovery-t1994544
the second method, and it went fine ive checked with check root and i have root access and the super app is installed too, but i cant use my virgin sim card as it says sim network unlock pin, unlock or dismiss, i thought once i followed that guide it would accept any sim card?

Hi,
Asking in the thread you linked is your best option.
Good luck!
well i used the galaxsimunlock and it worked so im very happy, can delete this thx so much to this forum, this is my first smart phone, it took me all night to find this solution, but also had to mess around installing all sorts of things to root the phone, things are never as simple as they should be either, had to install drivers to make adb cmd work and only certain ones worked, but now i got to try fix this battery draining problem
Great! This is your device section, for future reference..

Hi,
I need to unlock my device and my guess is I need to go back to Stock for the Tmobile Unlock App to work (does this even work in the first place?). So my question is has anyone used this successfully and also rooted/flashed another ROM after the unlock and it stayed unlocked?
If there are things I need to avoid after a successful unlock, please let me know that as well.
Thanks!
interesting
Well I know my N5 is unlocked under stock rom. After flashing a custom rom I lose the unlock. I've posted in other threads about this but there has not been a good answer other then getting an unlock code which I don't know how you would for tmo. But flashing an intl custom rom will let you get to the menu to enter the code to unlock. The question though is how and where would you get an actual numerical unlock code for a tmo device? Cellunlocker and a couple others I've contacted are not able to get an actual code to use for the tmo N5.

Thanks for the response. Yeah, my phone needs to get unlocked cause I'm moving to Japan and I rather unlock it than buy a new phone...until the Note 8 comes out.
I tried to Odin back to stock, but I get a DRK fail so I can't lol
I've been searching for a number of hours now, and I haven't found the answer I need. I have a rooted Galaxy Avant from T-Mobile with TWRP installed, everything is backed up and ready for any customer firmware to be installed. I need to get this phone unlocked. T-Mobile says they won't unlock it because I haven't had an account with them for over a year, but it was a prepaid service plan and I bought the phone outright. They just refuse to provide me a code. I understand that even if I HAD a code I would have to flash the MetroPCS ROM and use IT to input the unlock, but what I'm hoping for is a way to unlock with a customer ROM or something like that so I can use it with Cricket. Everywhere I've looked has either lead me in the exact wrong direction and tried to get me to purchase an unlock code, or it has only told me how to input an unlock code I already have. I'm fairly knowledgeable about all of this, but I'm stumped. Anyone who can give me a hand with this would be greatly appreciated. Thanks!
Hi !
I haven`t found any thread for sim unlocking for this device but you can post or search in here https://forum.xda-developers.com/general/help/discussion-galaxy-avant-t2845229
Good luck !
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.

Well, technically you can, but as of now it sounds like you'd lose the SIM unlock.

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.

I took the active H2o (At&t MVNO) SIM from my current device and tried it in this one. I could not make phone calls or access data, both in stock 20A and Resurrection Remix.

If I'm not mistaken, you can't unlock this phone with an unlock code.

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.

And there is no way to root the phone without downgrading to 20A right?

So if 20i is the latest, then it is possible that T-Mobile's variant of the phone could have a different model # than H830...
Hello.
I have searched the forums and they say there is no way to unlock the carrier for my model; I'm no expert, but what if I flash the ROM? Is it possible to unlock the carrier like that? So I went to the LG website and they have stock firmware files for flashing, the problem is that there is no exact copy of my model, so I was wondering if it is possible to use other ROMs for flashing my phone, like the only difference is the company carriers, there's LM-Q720MS, Q720MS, Q720TS, Q720VSP, I don't live in the USA so I don't know much about phone carriers; Since I have limited bandwidth I can't download all of them and experiment, does anyone knows if any of those ROM files are able to unlock my phone?
The answer is no this process will bricked your cellphone.

no, I don't know your answer, I'm on metro PCS, and was able to just request the unlock through the carrier app on my phone, and they did it right away
