[Q] Unlocking the T989 Revisited

First:
I know there is a fully legit method to unlock this phone via t-mobile. For what it is worth, I recently tried to do this and was stymied by the bureaucracy before I was able to get it done. Specifically, they apparently had a different phone registered to my account despite the fact I had activated it with the T989 (switched to prepaid) so I had to wait 24 hours for that to get into the system. Then I was required to FAX my proof of purchase but by then I was out of the country.
(Funny story: I got my g/f a legit unlock code, who is running a Vibrant. It didn't work, and we found this out in South Africa. Luckily I brought an extra phone which I had unlocked myself.)
Second:
Has anyone taken a serious look at this? I know there are ways to do this with various (kind of expensive) hardware, unlocking websites of various pedigrees, or taking it in to certain stores for a fee. But first of all where is the fun in that, and second of all, for people in a pinch all of these methods may not work. Best to have a DIY method where all you need is adb and a hex editor.
Third:
Unlocking is a pain anyways, because from what I read you have to go back to stock to do it, and who wants to do that?
Finally:
Does anyone want to try this? I am not a seasoned developer, but I am probably going to go through the official process of unlocking my phone, which means that if there is something I can snapshot, I can do it before and after, which might provide some hints as to where this phone is unlocked. Privacy issues must be respected, meaning I probably will be reluctant to share details such as my IMEI, but maybe we can all work together to figure out offsets or otherwise find a pattern useful in unlocking this device.
Thoughts?

Same thing about the vibrant here. I requested the unlock code from Tmo, and they sent it in a about a day. When I tried to use the unlock code, it wouldn't work. I used all attempts except one and it's still locked.I called T-Mobile and they asked me to send it in.

The rep you spoke to should have asked you for your new IMEI number so they can punch it in. They can run the unlock code thing whatever with your new imei too, I have no idea why they didn't do that.Thats what I did when I unlocked my phonessssss.

I got mine through T-Mobile. Only issue i had was the dummy who sent the email forgot to actually put in the code so i had to talk to a rep who gave it to me then. But i flashed to stock entered code, and was able to use the ATT sim card perfectly no issues.
BTW the reason for putting it back to stock, i think the apk required for entering the code isnt on custom ROMs.
And just outta curiosity, how do you use ADB and a hex editor to figure out the unlock code? i always wondered where the unlock code came from wondered how it was calculated and such.. it must just be off the IMEI since thats all any company or t mobile needs to get the code..

[Q] Unlock + questions

Hi,
I would like to unlock my T989. Although I've bought it at full price from Walmart I've got an email from T-mobile saying that "The device was not purchased from a T-Mobile USA retail store or authorized T-Mobile retailer." and I've decided not to battle them for 3 months and just do it myself.
I'm a newbie and the following questions might be silly.
1) I understand there is a software by z3x that unlocks the phone. Do I need an extra hardware for it (what is the z3x-box)? If so, what kind?
2) If I root the phone, will it be immediately unlocked?
3) Is there a free method to unlock this phone (assuming I'll root it successfully)?
Thanks!

You could always just take the simple way and tell Tmobile your taking a trip to mexico in 3 weeks (Cuz itll take 2 weeks at the max for the manufacturer to send the code to tmobile) and you want to use a prepaid service down there but dont want to buy a new phone. I just did this today, but act like you dont know much about sim unlocking to be on the safe side. The lady tried to get my to buy a new phone from tmobile down in mexico or just let my phone roam and get international charges and i told her "Well im trying to use the same phone with a prepaid service down in mexico so i wont have to have any additional charges when i come back, I herd something about most phones being locked so will i be able to use the prepaid sim on my current phone?" and after that she mentioned sending me an unlock code.. She tried to play me like i didnt know anything about sim unlocking by telling me my options were buying a new phone down there or letting the charges rack up. Then tried to cut the conversation off short this was in the online chat. But if you keep asking questions and explaining you dont want a new phone or to let them add charges theyll eventually tell you about unlocking your phone and ask for you imei and email then youll have to wait for 2 weeks.
Hope i helped a few people, I tried the method above and it didnt work for me. So i took the longer route that will forsure unlock your phone. :good:

Curiously enough, I'm currently abroad.
I don't have a t-mobile account. I don't even need one according to their website. It's just annoying. But I feel like I'm tilting at windmills.
"If you paid full retail price for a device, you qualify to have the SIM subsidy unlock code provided you meet the following requirements:
The device must have been purchased at a T-Mobile retail store or authorized T-Mobile retailer.
The device must be paid for completely. You must be able to fax the proof of purchase to T-Mobile."
In any case, as I didn't get an answer in the other thread, do you happen to know
1) How do I boot into recovery mode? and how do I choose to flash a radio? Do I need to install a specific recovery software? I would really appreciate if somoeone will able to post a detailed "unlocking for dummies" guide, starting from an unrooted phone. A medal of honor will be given if the guide will start from a stock, unrooted phone.
2) I understand the latest version of the radio is UVLI. Should I use it or use the one that comes with my phone? (I would like as few problems as possible)?

You have step by step details in the post mentioned by DupleX01.
- install recovery
- install radio SGH-T989_UVLE1_radio
- unlock the phone
- done
- you can change the radio again (look in the dev area for several radio packages that work with T989) - optional if the phone works well

SIM Unlock/Root Questions

Firstly, I'll say I'm new to XDA so thanks to all those who offer people like me somewhere to turn to. So, a little back-story, I recently got the root itch after my last ATT upgrade and it would seem it couldn't have come at a worse. For I had just recieved my ATT Galaxy s6 Edge Plus two days prior to being introduced to this site. Needless to say, I put too much effort in finding other devices essentially to "play" (root, flash, etc..) then I should. Which brings me to this...I came across this Sprint HTC 10 still with the plastic on it for a price I couldn't refuse. While trying to go about Unlocking the SIM I've encountered two issues: one being I paid to get an unlock code (actually double due to "high level of security") which ends up saying unlocked from network in a pop up but when I reboot with different carrier SIM, it still says SIMlock Enabled. So, Secondly, I figured try my chances calling Sprint even though I didn't have any of the sellers information. Only to find out, according to her, that phones aren't even elligible to be SIM Unlocked unless they have been active with the carrier for atleast 50 days. I would reallly appreciate if someone could shed light on this and let me know, since I bought it out the box and don't have Sprint, did I just buy an expensive paperweight? Also, if anyone could point in the direction of an effective SIM unlock method, it would be appreciated. And lastly, would rooting it make it easier or expand my options of SIM Unlocking? Thanks for any input.

I haven't tried sim-unlocking this phone but I usually get unlock codes from reputable sellers on eBay. If the code you received doesn't work, I would ask for my money back or ask the seller to help me troubleshoot the issue.

The source seemed to be a reputable and were extremely professional, (HTCunlockingservice.com), and said they got the code straight from Sprint server. I just don't understand why the code won't work. Any knowledge of how factual the service reps statement that if it hasnt been active for 50 days, it cant be unlocked?

SIM unlock lost by LG repair - hard to get back

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.

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.

Can I unlock a carrier locked bootloader (T-Mobile) by using the pixel factory flash

Hello. I just got a pixel 3a xl, but it is bootloader locked to T-Mobile, I see Google has a pixel repair tool to reflash the pixel to stock. My question is it asks for your carrier, if I change the carrier to a different carrier that doesn't lock the bootloader will o be able to unlock my bootloader to flash root.

While I could not say for sure, I suspect the answer would be 98 percent no.

Thanks I want to try but it's my only phone and if it is down for a while I have no phone and I need 2FA for work.
If I try I will post here

You cannot unlock it from T-Mobile or unlock the bootloader, even with the flash tool... The flash tool does not/cannot modify that part of the phone, if it was that simple people would be doing it all the time.
Only T-Mobile can unlock the SIM, once that is done you can unlock the bootloader. Your only other option is to go through a 3rd party unlock code service, which can be sketchy according to some people (I have done it a few times without issue though).

I want to verify this.
SO if I buy a used T-Mobile 3a XL that is paid in full, I should be able to get it SIM unlocked by the carrier correct and if its carrier SIM unlocked, I CAN unlock the bootloader?

As long as it is not the Verizon model 3a, then yes. You can bootloader unlock it once it is SIM card unlocked. Only the Verizon models permanently lock the bootloader.

Question 2...
SO lets say I buy a T-Mobile 3a XL and it works fine with a T-M SIM but is SIM locked... Can I pay someone to unlock it and then still unlock the boot loader?
Someone know has a new in the box T-Mobile Pixel 3a XL I can have for $225.00 but its never had service on it and it sounds like it has to be active on T-Mobile AND have had seriver for 40 days to get them to do it.

I've seen unlock services being advertised, but I have also seen people post that they don't work. It would require that someone hacked or has access to the T-Mobile locking software which isn't out of the realm of possibility, so it's possible some services do work.

Hello friends, I need your help! Who can help me raise my brick and make a full backup of my smartphone using qpst?

Update. So I ended up buying a T-Mobile Pixel 4 XL when they went on sale.
Search my name and look at the thread reply I just posted in the Pixel 4 XL forum about T-Mobile unlocking.
I included pictures.
I just purchased a Pixel 4 XL, I'm brand new T-Mobile subscriber, the phone is not paid off and I have it on a lease and I've only been on the service for 4 days.
I currently have the T-Mobile Pixel 4 XL with both a full SIM card unlock and OEM bootloader unlock.
I'm currently running the phone with an AT&T physical SIM and a T-Mobile eSIM.

Have any recommendations? I have a brand new Pixel 4 that an online retailer lied about being unlocked & is T-Mobile carrier locked & they're completely unwilling to release the Sim from their network. I'll take the sketchy unlock service. I tried one in ATL friend gave me a number but most only do Samsung's or iPhones for obvious reasons.

Not just Verizon though right? I heard Sprint does too.

Keep in mind there are SIM locks and bootloader locks. Every US carrier SIM locks you phone if it was bought in an installment plan. Once the phone is paid off, I think every carrier will SIM card unlock the phone.
All recent Pixel versions have to be SIM card unlocked before the bootloader unlock option is available. So you have to have a SIM card unlocked phone before you can bootloader unlock. But Verizon is the only US carrier that has asked Google to permanently bootloader lock their phones. Sprint and others don't weigh in on the subject and Google's policy is to allow bootloader unlock. This isn't necessarily true with other phone brands however.
As far as getting the phone SIM unlocked, the policy is to not do it, so it's rare to find a call center person that is willing to do it whether you call in or chat with someone online. However, the success stories that I do see are usually done by DMing the carrier's support group on Twitter of all places. Explain that you need to get the phone unlocked and many times they will do it.

I can confirm this. I'm on TMO and I reached out on Twitter and got results. I'm not a big Twitter fan nor do I really use it, but customer services seems to be more in the loop there. I told them that I wanted to try the dev preview of android 11 and I needed to bootloader unlock. For that to happen I needed them to permanently sim unlock my phone. (Technically you can install the preview with a locked BL, but since it's a preview you can't re-flash anything lower or rollback without the BL being unlocked). Hence the dev preview. Anyways, I was polite and truthful about my intentions and they got it sim unlocked, fairly quickly too.

Its bootloaders unlocked I was almost done rooting it but haven't; refrained because I don't want to violate the software warranty incase I need to return it, & find another way to do so for a refund. I called support multiple times same answer, & then Twitter dm'd last night they were again unable to do anything so they say.
They cite "privacy issues" but I know it's a ****ing money grab they don't want to unlock it unless you want to pay for one of their plans & get tied in a contract for a minimum amount of days first & I'm not going to ****ing do that. It's ridiculous to me carriers behave this way. This is why I believe in hacking because you can't trust companies for absolutely ****.

You got results? Look at my next post, can you tell me your secret because they're being serious assholes here. Not a single company involved with this situation is helping at all.

I'm a little confused. You say it's bootloader unlocked and you were about to root it but decided not because of warranty concerns correct?
Typically, whenever you unlock a bootloader your warranty is void then and there. That is in most cases and I assume is the same in this case, though I don't know that for a fact with a TMO Pixel 3a XL. I just assumed it was and most likely is. The reason being is you can flash anything you want, and there is no way to guarantee that whatever has happened to warrant a claim wasn't due to user error or unofficial software. A locked bootloader kind of guarantees that nothing unofficial was flashed and that's why warranties are usually based around their status and why a flag is marked when it is. So even if you re-lock it, the flag still shows it was unlocked at one point.
As for actually unlocking it via TMO, the phone uses a TMO app to actually unlock it. It basically checks your imei against their server to see if it is eligible for unlocking. As for citing privacy concerns, basically you have a TMO phone and no account it seems, and you want it unlocked. For all they know it could be stolen, and as far as proving it's yours legally without any account... probably more than they want to deal with and I'm sure they have liability reasons as well.
All I know is, I've had an account for quite some time. I've bought several phones through them, so no issues. Technically I'm still on installments with this phone, so they could have easily said no, not until it's paid off, but I like to think they said "Oh it's Airwalk... he's cool af, go ahead".

Only Sprint & Verizon manufacturers lock the bootloaders of their phones T-Mobile doesn't. TWRP doesn't even exist for Pixel 4 because dude's too busy with wife & kids to update so flashing is difficult until you root it first unless you feel like doing a tethered through ADB. I know Samsung has the "Knox" & figured it's similar to that. Unless it's tripped it's negligible.
I know how the unlocking app works. Also, It's not stolen my situation is similar to the below it's "super whitelisted" I've had multiple services run the IMEI & it's come back clean. The phone meets all the unlocking criteria of which is being legit paid for is one of them.
They're just not releasing from the network. I need a workaround, I'm not trying to go through an entire claims process & have it sent back when aside from "network lock" it works just fine.
****ing Greedy ass corporations.

Ah, Pixel 4 needs sim unlocked, I was confused because this is 3a XL and I wasn't paying enough attention. I see your frustration now. I don't know about that one, just (bonito) here and it was all easy for me. I suppose that if you don't meet their requirements it's all too easy to just lock you into their script. I can't help you here, sorry. I think you'll just have to be 'that guy' and persist with them. Good luck.

No quicker way to loose all goodwill and help from people than bad mouthing the generous developers.
Feel free to come up with your own TWRP solution. Until then, STFU.

That isn't even the subject of the thread. If you're going to ignore everything else I was saying & completely miss the point to focus on a single cherry-picked remark that triggered you then you can take a hike. Don't respond. Go invest your frustrated energies elsewhere
You know what? Maybe I will take the source code & develop my own unofficial TWRP build for it. Hacking & Technological communities don't just stop because you want to "move on with your life" we still need these tools. You think journalists whistleblowers & Chinese protesters can "do without" Tor?
