I've tried a few services online and none of them can unlock (sim/network) my LG G4 H812 (Canada). Abit long story, but I bought this new from WIND a few months ago, but switched to another carrier (Mobilicity) recently and unlocked it fine. But soon, the G4 had issues so I received a warranty replacement with a different IMEI. During this warranty process, the service center asked who the original provider was, so I said "WIND". I assume that meant that the replacement was locked to WIND again.
OK, np I thought, I would just get the replacement and unlock it again. But for some reason no one is able to unlock it. Is it because this new phone has never been activated with any carrier..? How am i supposed to do it? I no longer have the WIND sim either.
Thanks,

I'm having this exact same issue. My LG G4 was bought brand new from Wind about a year ago, but was sent in for repair through Wind's warranty service. I had the bootlooping issue, so my phone received a new motherboard, and subsequently a new IMEI. For resale purposes, I tried to SIM unlock the phone through multiple third-party services with no luck. I then tried asking Wind for the code directly, which they didn't have (I assume this is because it is a brand new IMEI), so Wind told me they'd request a code directly from LG. I received the unlock code a few days later, but even that code doesn't work. I'm honestly stumped, and my phone's now down to only 2 SIM unlock attempts remaining. Did you ever end up having any success with your phone? Were you eventually able to get it unlocked?

What issue did you have with it to need it repaired in the first place? Since the unlock code that I received from LG directly didn't work for me, I'm a little hesitant about using one of my last two unlock attempts on cellunlocker.net, a third-party service. BUT, seeing as they worked out for you, I'm somewhat hopeful.

I had my G4 repaired last year when it suffered the Bootloop issue, It had a custom rom and unlocked bootloader back then but they still fixed it (assuming they couldn't even get it to boot fully)
Long story short, My G4's charging port began to be very temperamental, and I was getting rare bootloops so I sent it back again seeing as it was under Guarantee. After my phone sitting at the center for 2+ weeks without any updates I emailed LG to be told that because of the unlocked bootloader it was out of guarantee.
Has anyone tried to push on with LG and get it fixed after they deny the repair?
If they received your phone and IMEI was confirmed to be unlocked, then you're either getting the spare parts yourself or looking for a new one.
They actually have to repair it.
Maybe it will help if you put preassure on them.
That's not cool, how the hell unlocking bootloader could damage USB port.
Don't know the laws in UK. But lg Sweden have always repared my devices always unlocked.
One time thay couldn't repair it and sent me a store credit for a brand new device 480 usd even more then I payed for it?
Unless they can prove that unlocking bootloader caused the faulty USB (which they obviously can't) then you are entitled to it. Pressure them.
If not, get it back, relock bootloader and send back again.
i have a tmobile Z2 i bought online and was not able to unlock it. It is very clearly a tmobile version but when i tried to use the unlock from tmo it say i am not eligible for an unlock i then called and they said the device was not sold by tmobile then called moto and got the same story. as of now i stick in an att sim and it does nothing only works on a tmo sim. any advice on how to carrier unlock this device.
T-Mobile devices require usage on the network before an unlock is allowed. Sometimes they will allow an unlock without use on the network, but since you did not buy the phone from them that most likely will not happen.
What is the error message you are receiving? If it is the device is not eligible, than it is in the server database and you should be able to unlock it after you have used it on the T_Mibile network.
If however you are receiving an unknown error, than the phone is not listed and you'll probably never get it unlocked.
Either way, it might be easiest to return the device to the seller if you're still within the return period.
Well even if I cant unlock it yet I have a friend who would be willing to use it for sometime and let it get time in on his account. The phone was already in use on the original sellers account so I thought that was enough. I will slap this tmo sim in it and give it some time it's the device I plan to do development on. I have a z2 from at&t so that my daily and this one can get bricked for all I care. I want to support the Z2 community
I had the same issue. Look for my post in the older unlocking thread. It's very straightforward and you can use a prepay sim to do it.
A small warning here for those who need to send a previously SIM unlocked H932 in for LG repair:
After breaking its glass back, I had to send my TMO V30+ in for repair at LG’s center in Texas. At the same time I asked them to replace the screen under warranty, since there was a small cluster of dead pixels just above the navigation bar. They did all that. Cost $88 (including free shipping) with 11 days turnaround.
They also managed to lose the SIM unlock which I had previously been granted by T-Mobile using their Device Unlock app. Realizing this could be a problem, I had included a letter to LG Repair where I begged them to preserve the SIM unlock. Needless to say, the phone is paid off and all bills were paid (including the extra month TMO auto-charged my credit card and refused to refund).
After receiving it back, my Red Pocket GSMA SIM (AT&T prepaid MVNO) only does 3G, not LTE. The TMO Device Unlock app says the phone is “network locked” and not eligible for unlock.
T-Mobile Customer Service first requested unlock instructions to be emailed to me. After 2 days I received an email saying I had to use the TMO Device Unlock app. Duh. After much experimenting on my own (including with my now inactive TMO SIM card) I went to the T-Mobile store where I bought the phone. They were keen to help, but unable to solve the problem. We did confirm that with an active TMO SIM, everything was fine.
I then called TMO Customer Service again, this time asking for Tier 2. Here they finally escalated the case and requested an unlock from LG and said to expect a solution within 72 hours.
Different from the issue reported by @michy21 in this thread mine is the SAME phone with the same IMEI; it was just wiped by LG repair in a way that lost the SIM unlock. OR it really is a new phone or motherboard and they transferred the IMEI.
I should add that there has been no pushback or reluctance to help from any T-Mobile staff. It’s just that the company has baked everything so hard into the Device Unlock app now, so no human is able to do anything.
The only lesson here is to never buy carrier devices -- as @ChazzMatt has been stressing all along, and as I had been practicing myself in my Nexus days. But unfortunately carrier devices are where the best deals are -- which is the only thing that made it possibly for me to buy this class of phone in the first place.
I'll update this thread with the final outcome. Fingers crossed. I’ll be traveling overseas soon, really hope to have it fixed before.

Worst comes to worst, sell the phone on eBay while at the same time buying one of the mint LS998 V30+ for $320. Immediately convert to carrier unlocked US998, bootloader unlock and root.
In the eBay listing for this phone stress the T-Mobile band 71, blah, blah, blah -- which you don't need on AT&T MNVO, but would interest T-Mobile users.
Sent via open market LG US998 V30/V30+

Thank you, Chazz!
I had a suspicion you might suggest that :laugh:
But yes, that would have to be the outcome if I cannot solve it. I'll probably file an FCC complaint first, which michy21 reported had solved her problem. But again, there is no pushback from anybody, which is a positive.
The only attachment I have to this particular phone is my 2 year warranty, which gives me peace of mind. A phone bought used wouldn't have that (or any warranty).
Thanks again!
Edit: Actually, it's not quite true that I have no other attachment to this H932: If/when T-Mobile rolls out B71 in this area, I'll probably give them another try, as they generally have far better network speeds. AT&T service here is acceptable (and widespread) but doesn't blow me away. We only switched because TMO couldn't reach through our concrete brick walls. Red Pocket supports all four carriers, so I can switch to TMO network on my current plan to take advantage of B71.
So my hope is I won't have to part with this phone. AND that @runningnak3d will release H932 root later this year

That does not make sense at all. Has the device IMEI have changed at all? Was the actual logic board replaced? The answer is likely no. So why would the device be relocked by LG? You are giving them way too much credit.
More proof that the device should have remained unlocked is that you can access the device with your MNVO (ATT), if it was truly locked you would not able to get a signal or make a call under your MNVO at all. Sounds more like user error or a miss configuration of your carrier, or both.
Also you should not be trying to run a T-Mobile Specific device unlock app under a different carrier sim,
and it might just be reporting wrong information. Had this happen to me several times in the past, when the device was actually unlocked. You said yourself, you were able to use the device on (ATT)!

Thank you. I understand where you come from. And no offense taken
The problem IS a SIM lock (or "network lock" as they call it). But not in the same way you're thinking where nothing works with an alien SIM. Both T-Mobile and LG have confirmed that.
Some details I didn't mention in my opening post (I meant to warn people here, not argue the matter):
1) LG warned me before they began repair that the phone would come back SIM locked, even though I'd included a letter asking if they could avoid it. I also talked to T-Mobile before sending it in, who said to just request an unlock code if needed (obviously that person was clueless).
2) I've seen other XDA users report how SIM locked V30s could connect on different networks, but NOT get LTE. That's what I am seeing too. One of my goals with visiting the T-Mobile store was to verify that there wasn't a problem with the phone itself preventing LTE. But once an active TMO SIM was inserted, everything works flawlessly.
3) I thought the same thing about not running the TMO Device Unlock app with the alien SIM inserted, but TMO's wording in the instructions they sent me are: "Before completing the steps below to unlock your device you must be connected to the internet via a cellular network in order to complete the steps", not mentioning it must be on TMO. And I DO have 3G internet with my Red Pocket SIM. Nevertheless, my second goal with visiting the T-Mobile store was so we could try the Device Unlock app with an active TMO SIM. And regardless of which SIM is inserted, the app reports that the phone is currently network locked and not eligible for unlock. When running this app on an unlocked phone, it shows the date of unlock -- even after a factory reset. They are obviously storing the lock/unlock state on the vendor, modem or carrier partitions or some such place. And on my phone it is in a locked state.
4) There is not much room for user configuration error here: The phone has been factory reset 5-6 times while testing this, with the only configuration being a Red Pocket APN. That same SIM and same APN work flawlessly in my Nexus 5 as well as my wife's V30 (also H932). Even if I mis-typed the APN, I wouldn't have done so 5-6 times -- and I would have caught it during one of the many times I verified the APN.
So I have no doubt that there is some form of network lock in place that is causing this. And again, T-Mobile and LG agree and have promised to solve it.
You are right that LG had no reason to replace the mainboard. But they did replace both the screen and the glass cover. I think it is possible that they sent me a refurbished phone with my IMEI transferred -- which would explain both their warning that the phone would come back locked, and why the Device Unlock app gets confused when seeing a blank (still locked) phone, but T-Mobile's IMEI database claims that the device is already unlocked (as I saw on the screen in the store).
So, we'll see if they manage to solve it or I have to sell this phone as suggested by Chazz.
Would paying a 3rd party carrier unlocking do the trick? Or does even that seem out of the question now? Before Frankensteining was a thing I did that so I could use an H931 on T-mo. It was $10 well spent as far as I was concerned.

Thank you for the suggestion. I'd have no objection to that at all, but various reports on here had given me the impression that 3rd parties aren't able to unlock the H932 because TMO locked it down so hard (as is the case with Sprint, but for different technical reasons). I could be wrong about that, so definitely something to try.
Thanks again!
Update: It's been four days since I talked to T-Mobile and they promised to escalate my problem and request that LG provide a solution. They said to expect a response within 72 hours, but I haven't heard back from them.
But yesterday, when I tried popping in my Red Pocket SIM (it's in my Nexus 5 until this is solved) everything suddenly worked: Instant LTE, which stayed all day, even as I drove an hour away across town and worked there for a few hours (using hotspot), went on several errands, and back home all last night. LTE Discovery Log showed how it had switched seamlessly between towers, without ever losing LTE. I was certain they had fixed it, and was much relieved.
Then this morning, it had locked itself again. Phone had been on all night, clearly T-Mobile must have pushed another lock. Or rather: One of the TMO services/apps locked it after pulling TMOs servers. No amount of Network Resets, reboot or toggling Mobile Network settings have worked to get it back. I promised T-Mobile not to make any more attempts with the Device Unlock app as it messes things up for them, but I am sure it it would still say "Ineligible for unlock" even though the IMEI is clear in TMO's database (and listed as already unlocked).
As always, the same SIM gives perfect LTE service in my Nexus 5 and on my wife's V30, with the same APN.
I called T-Mobile Customer Care and was unable to persuade them to transfer me to Tier 2. But they did says to expect a call within a day.
It is almost certain I'll have to go the FCC complaint route. It's sad because T-Mobile is otherwise not a bad company. Probably just a small handful of idiots who got this "bright idea" how to protect TMO phones -- which ends up causing so much trouble for legitimate customers.
@jaysus145: Which Unlock service did you use? The ones I looked at which support T-mobile unlock cost $75-150 -- and they don't seem to guarantee success.

T-Mobile called me back yesterday and assured me they were still working on it and they would get this phone unlocked and please sit tight another day. They confirmed there was nothing on the phone's IMEI or my old account that should prevent it.
I'll check out unlocking services if it comes down to it.
Thanks again!
Final update on this (and solution):
T-Mobile solved the server side problem with a manager override, so that the Device Unlock app now says "Permanent Unlock approved". But it continued reporting "Unlock Failed" nevertheless. Some say because the phone is already unlocked, personally I think because the servers report the phone as previously unlocked. The app also says "Phone is currently network locked" when first running.
Notably, the connection problem persisted, and T-Mobile (after discussing with LG) said it had to be a bad SIM card or a problem with that SIM ICCID and my phone's ESN. As previously described, I get perfect connection and service using the same SIM in my Nexus 5 and in my wife's V30. T-Mobile said that was all they could do.
I then decided it was time to take the matter in my one hands. After much searching and countless Factory Resets and Network Settings Resets, I managed to get the phone working right with the following steps:
1) Remove Google account to disable Device Reset Protection.
2) Factory Reset from the Service Menu: *#546368#*932# (replace 932 with your model number, though this is likely a T-Mobile only problem). From there SVC Menu - Factory Reset (R&D Only). This takes quite a bit longer than normal Factory Reset.
3) Initial setup with WiFi, no Google account. No APN. Phone shows usual connection slowness.
4) Airplane mode, then WiFi on.
5) T-Mobile Device Unlock app, Permanent Unlock. Got the same "Unlock Failed, but Approved" message.
6) Enter APN.
7) Network Settings Reset (Android Settings - Reset menu). Wait for reset to complete. It may go straight to LTE already here.
8) Power off/on.
After this, everything is back to normal. Instant signal and LTE connection, even after subsequent Factory Reset. It's such a relief :laugh:
Edit: I should add that it is quite possible that not all of these steps are required. Probably the Service Menu Factory Reset was the key to undo what LG had done during the repair. I am merely listing all the steps which I used, and which brought my phone back to life.
Well since I have found zero threads about AT&T bootloader unlock. Does anyone have any solution? Whenever I put in any other sim, it just says that unable to use any other sim apart from AT&T. So I just factory resetted my phone and blocked the device setup app from accessing the internet via the Netguard app. That's allowed me to use any SIM card apart from AT&T however it's not a permanent solution but I'd like to know my options. Any chance of me working around a carrier unlock or possibly bootloader unlock? I bought this phone outside the US, and to my stupidity I never factored in that this was also a possibility that it's carrier locked, that too with a bad standing. I tried unlocking online but it just says that there's payments overdue and that I should log into my AT&T account. Tried calling their customer service, however they're useless and unhelpful. Learned the hard way, depressed that I've kinda wasted my money. Can there possibly be a way to carrier unlock my device and bootloader unlock?
Can you return the phone? The seller should have disclosed that information and the phone will technically only be used on AT&T until it's paid off, and currently on AT&T (for 60 or 90 days before they will sim unlock)
I tried going back to the shop, they just said that there's no way that they offer returns and that I should just contact AT&T for this issue. I'm running out of options and patience. I'm basically stuck with this phone. There's really no check and balance here when it comes to these matters
