Sim unlock code not working - Galaxy S 4 Q&A, Help & Troubleshooting

HI,
I purchased an unlock from a local shop. After many attempts the code was not going through.
The vendor then provided an "unfreeze code" after which I was supposed to enter the original code again. Many attempts were made, all unsuccessful. The vendor told me its an unusual situation as the codes always work and was unsure what further steps to take. (Before anyone says its a scam, I highly doubt it, as its a reputable store and they happily gave my money back)
So back to the problem, is this an issue anyone has faced before, is there a way around it? I really needed my phone as I'm going abroad tomorrow and it would've been extremely handy to have net access.
I've read in a few places people recommending going back to stock and trying, but I don't wanna risk it right now if there's no truth to it

Has anyone unlocked their g1 running on cyanogen?

Well, the story goes like this:
Bought a g1 and the second logical step was to put in cyanogen. After a while I thought that an unlocked phone would be even better. Went online and purchased the unlock code and tried to use it while running cyanogen. Did not work. Flashed to rc29, tried again, did not work. Then I went to another unlock provider and this guy, gave me the same code as the first, based on my IMEI ( I don't have a fake IMEI), he tried it as well and did not work. Then he searched for different version of the code based on the IMEI for different htc products ( it seems that they have some accounts with htc and for IMEI they receive the unlock code). We also tried it with a goldcard which only made my g1 scream that I don't have a simcard inside.
Bottom line, did cyanogen mood do something to the unlock procedure ( hard locked the phone on tmobile - on tmobile the phone works fine) ? Or I just happened to have a weird phone, Thank you.
Btw, my unlock code is 92179512. Feel free to try it. It would be funny as hell if it were to unlock someone elses phone, and if it does, let me know as well.
I unlocked my phone on a MUCH older version of CM, so I wouldnt be able to tell you if anything has changed to effect the process. However, if you're a TMO customer, you do know that after 90 days they will GIVE you the unlock code for free, right?
I also have unlocked it on Cyanogen mod, but I believe I was on 4.2.7.1 at the time.... not that long ago really.... but T-Mobile does indeed give away the unlock code for free, and it worked flawlessly.
Neither the ROM, SPL or radio can effect the simlock. It's not Cy's ROM that's causing the problem...
What do you mean 'it doesn't work'? Does the phone reject the code?
Thank you for the reply. Well the problem is that I don't have a contract with Tmobile since I don't have the money for it. I bought it off from someone and used Tmobile prepaid sim card, which works fine. And, because of that, Tmobile won't provide me with an unlock code .
Regarding the code, when I type in the code it says network unlock unsuccessful, so I can't do much about it. I'm trying to update to the latest stock donut and see what happens.
Ah that sucks :-( I really can't of any options for you, since any codes generated will always be the same...
nope -

notice in the replies above, that cyanogen nor spl, nor anything software related can change your unlock status.
you already have an unlock code, and since you've had it generated from two different sources, i believe that code is correct for THAT IMEI number. that being said, did you copy the imei number from the sticker on the inside, or from what the phone shows in "PHONE INFO" ? I'd make sure they both match.
i also have a phone that is flacky about SIMs. haven't found an explanation yet, I think some of the boards have bad solder joints, or there is another hardware problem that causes similar errors. no proof yet.
try a friends Tmo sim card, and if his is recognized, and allows data connection, you'll know it's your phone that is locked, and that all the hardware is working. i'll bet you entered the wrong code because the sticker inside was wrong, or you fat fingered it. just a guess.
good luck, please update the thread when/if you find a definite answer.
I would bet the IMEI on the sticker and on the board are different... where did you buy said phone and for how much? It could very well be a refurb, which will have bits and pieces from several different phones, and thus could have the SIM locked guts for phone 666 and the case from phone 888 type thing.
Yep, checked it 10 times the first time I bought the code online. The same imei in about this phone is on the sticker. After I saw it did not work, I went to a local unlock shop around my place and the guy there checked it again more than 6 times. So.. weird eh? And both guys got the same code from HTC based on that IMEI
Sounds like this may be a hardware error. If that is the unlock that is generated then it should just work. The unlock does not really pertain to the rom or anything else that people usually mod. Also, maybe ask that dude why he was giving up that phone, maybe there is really something wrong with it.
the only other thing left is get an turbo unlocker chip that sits between SIM and phone
pain in ass to install but I have done it with out cutting the SIM card
I am guessing someone had typed the code in incorectly .. they can be permiatly locked if wrong code has been entered
also just because it was another person does not mean their MEI source wasn't the same
I guess they worked out they work ,,, I payed $5 for mine .. now 4x the price
http://cgi.ebay.com.au/NEXT-SIM-TUR...wItemQQptZPDA_Accessories?hash=item4cec3cab8c
The unlock codes sources are all the same. I lost over 100$ trying to get unlock codes from them but 80% of them don't work (only the ones for htc phones). I use a turbo sim with my G1 and is really easy to install. just buy one and cut your sim where the CHIP from the turbo sim is located. It works flawlessly.
Im just throwing this out there to say that I was able to successfully unlock my g1 with CM 4.2.10.1
Other than that I would just be repeating what was already said if I was to give any advice.
Best of luck man.

You're welcome to try it with my sim card. But you're probably far far away.

Actually, they will give you an unlock code after 90 days of being a customer and every 90 after the last time you got an unlock code. They will give you an unlock code the same day you buy the phone if you meet those requirements.
Sorry if this is irrelevant to the rest of the thread, but assuming I unlock on JF 1.5 (yea I'm behind) to ATT, and wipe everything to install a HeroUI ROM of some sort, will the unlock still be in effect or will I need to unlock the phone again?
Thanks.

You'll be ok.
I actually like JUST did it on a coworkers(I admit, going from WiMo to Android is a learning curve, but its easy), he got his from craigslist, had JF 1.5 on it. He used it for like a week, complained about sluggishness (he did have like 20 apps constantly running) Anyway, after a few beers and lurking here (it was when I was deciding what HTC to get) we decided to go to CM (latest build). Everything went fine step by step.
I cannot vouch for your particular ROM but for CM it was fine.

i337M Abrupt Signal Loss

Hi everyone,
So about five days ago I was in the middle of using my Galaxy S4 (I think I was playing a game or something) and all of the sudden my cellular signal dropped out completely—from 4 bars to zero with a little X in it. There it's remained ever since.
My first thought was that I ought to reboot the thing and see if that would solve anything. The answer was no.
My second thought was that maybe my contract was up (as that was due to happen this month), and rather than auto-renewing, they kicked me off. Weird, but possible. But that's not it: I phoned up my provider and they said that all systems are go, there are no outages, your account is active for a week still, and even past that contract expiry I'll just get bumped to month-to-month and never experience a blip in service. So that's not it.
So then I put my SIM in another unlocked phone, and lo-and-behold, it connects just fine. So clearly the problem is with my phone.
My i337M is running Liquid Smooth 2.9 and KToonSez' kernel. I decided to make a nandroid and flash back to stock ROM/kernel. Still I could not connect to the network.
I can only think of two potential problems. First, I unlocked the phone myself via FastGSM.com's tethered USB method. It was a Bell-locked phone, and I'm on Rogers. This was accomplished back in July, and since then, there haven't been any issues to speak of (i.e., the unlock worked flawlessly). I tried to see if those unlocks ever expire, and couldn't find any reason why they ought to. I personally don't think it's that, but I mention it out of interest in being thorough.
Second, I messed around with my phones NVData a few weeks back to enable the AWS network via this method. I didn't experience any signal problems after doing so. Again I mention this out of interests of being thorough. Could that have had something to do with it? I suppose I could try flashing back my original NVData, but honestly I don't see why that would suddenly kick in now since I did it weeks ago originally.
Any thoughts? This is really bizarre, and it sucks being without connection.
I was also thinking of flashing back to stock and going to a Bell shop to see what happens when I put a tester SIM in.
It sounds to me like it's hardware related. Don't see anything you've done that would have caused it. I'd flash back to stock and if it still persists I'd file a warranty claim.
Sent from my SAMSUNG-SGH-I727 using xda app-developers app
Hi, thanks for your reply.
An additional thought's occurred to me: I lost signal at or about the same day I setup Android Device Manager to allow for remote lock/wipe directly from Google. That couldn't possibly be responsible for signal loss, could it...?
Currently flashing back to stock, and I'll unroot/restore kernel/restore NVData and make it look factory, and see what the store says about it. Hopefully I don't have to pay for another unlock at some point.
Okay, this is very messed up. Nobody has any idea why my phone isn't getting signal. I can scan for networks and everything shows up, but in any case with any SIM it says "unable to connect to network". It doesn't matter what ROM I'm on. I flashed back to stock and updated to latest using KIES of all things, which found a firmware/modem/baseband update, and still no dice. I don't know what to do with this thing except take it to an unlocking store that might be able to figure something out for me, but it'll cost me. This is messed, I've never had to get someone else to look at my tech for me.
Okay, so the situation is that it most probably is a hardware failure related to the radio.
I am a Rogers customer who bought the phone from a guy from CraigsList who apparently got it from Bell. I went into Bell and explained the situation, and they scanned the IMEI and printed me out a proof of purchase of the guy's name and told me I should take that to the Bell service centre, and it doesn't matter if I'm not the guy. I also had them check to see if he reported the phone stolen; it turns out he did not—though it should be known that if he had done so, then that could have very well been the reason I wasn't getting signal from anyone, as all providers across Canada apparently share their blacklists with one another now (including the little guys like Wind/Mobilicity).
So now I am in the process of making it look like it's never ever been hacked before: I shall restore my NVData, unroot, and update everything using KIES, and then perform a factory data reset. I'm also on the hunt to figure out what the heck the "flash counter" is and whether or not I need to reset that, but perhaps since mine is the i337M Canadian variant, I don't need to worry about that. (Any advice on restoring my phone to factory condition would be welcome, thanks.)
Edit: Figured out TriangleAway and everything associated. I'm all stock now and ready to bring it back to the factory.
MAJOR UPDATE: PROBLEM IDENTIFIED
So I got my phone back from the factory today. They reported that everything is 100% a-ok on the hardware/software side of things. The radio IC is NOT blown as was suspected.
You know what they said? The problem is on the network. I have a story to tell that I think people should hear, as I've learned something very valuable today and people need to learn this lest they get conned themselves.
Today I phoned in Rogers again, armed with new information, to ask what's up. They ran the IMEI number, and this time... it's come up on the blacklist.
It wasn't there last week. In fact, it wasn't even there an hour ago. It actually only appeared there as the clock ticked past midnight Eastern time... as that is EXACTLY 90 days from when the phone was reported missing. It took them a long time to track down this information.
To reiterate, I did not steal the phone. I bought it from a guy on Craigslist who had it brand new in box with the screen-protector sticker still on the front of it. I checked it out, tried it, and unlocked it myself and have been using it since July without issue, until a week ago.
There is the trouble of, why now? Why only now does the IMEI come up blocked? What the senior rep at Rogers thinks happened was that the guy had it delivered to his house, didn't sign for it, kept it in box, reported it as "undelivered", and flipped it to me for cash. Insurance has meanwhile hooked him up with a new phone, and the factory kept my phone in the "we're looking for it" pile for the requisite 90 days, after which they officially publish its IMEI as "blacklisted". That would explain why it worked for a while but doesn't now; and this 90-day TO THE DAY period is the same for Rogers as it is for AT&T apparently (which is where the rep used to work for 10+ years).
I am in possession of stolen property. I've little hope of recuperating my losses. I've been advised to file a police report, and I think I will actually, given that I've got a receipt with the "anonymous" guy from Craigslist's name on it which I had printed out from Bell after they scanned the IMEI number for my factory warranty receipt. This phone will officially never work in Canada, as there is no way for it to be removed from the blacklist. I've been very unfortunate in this case, and it's a real shame.
People should take note: If buying a phone, ALWAYS do it in-store and have the IMEI number run first to check and see if it's on the blacklist. Next, have the phone transferred into your name so that the IMEI and you are officially linked, and the guy can't report his gear stolen or lost. That should suffice in most cases... except in the case of insurance fraud, which is my case, where there is a 90-day delay period in the IMEI number being added to the blacklist (which is why it didn't come up on the blacklist last week when I had the Bell rep run it in-store for me). Another point of interest is that in my case, I found it was possible to lose service BEFORE the number is on the blacklist—assuming the Bell guy didn't run the number wrong last week.
So f**k me. All I can do is try to hack the number, I guess, or find a way to spoof the IMEI.
Edit: Unf***ing believeable—I somehow reenabled data and texting by messing around with QPST. Calls still not happening, though.

Note 4 locked by Rent-A-Center

I just bought a Note 4 from a pawn shop. I checked the IMEI with as many online free checking services that I could find. After I connected it to wifi, I started getting these pop ups saying that the phone is owned by Rent-A-Center and it needed an unlock code. I did a little searching and I guess this is a fairly new thing as of a few months ago. I was able to return it to the pawn shop and cancel the transaction, so I was lucky, but other people who have had their phones for months are all of a sudden getting these messages and being left with no real recourse.
I know this is part of the risk when buying a used phone, but I wanted to see if anyone knows a work around for this? I saw some people were able to install CM and then had no more problems. Someone else was talking about deleting certain partitions that don't get wiped during a factory reset. So does anyone have some good info on this problem??? And just a warning to anyone buying a used phone, you might want to call Rent-A-Center and ask them if they have anything to do with the IMEI number in question. If they are going to lock out a phone, they should find a way to be listed on the free checking services.
Here is a good thread with some info
Found this thread here on XDA
http://forum.xda-developers.com/android/help/rent-center-locked-galaxy-s5-t3070877
It has some good info about various ways to get around the problem. I just wonder if RAC will eventually blacklist these phones instead of just having a software lock.

LG V20 H918 Unlock Code used/Successful?

Hi there guys,
I seem to have an issue, on my LG V20 H918 I order an unlock code. I figured out a method to make it prompt for the code and bypass the T-Mobile unlocking app all together, however, here's the issue.
I received Three codes in with the markers
NCK:8565570142041856
SPCK:9791172928931644
NSCK:2448289909387735
NOTE: Codes included because they do not identify me or my device directly.
First I entered NCK and got "Network unlock successful" and went on assuming that was the end to it, however, after rebooting it prompts me for the Network Unlock Pin again. After entering the same (NCK) I was this time told the unlock was unsuccessful, so I tried the other codes provided all with the same Network unlock request unsuccessful response.
So my ultimate question is, what the you suppose the first success did and how can I finish the job? If it weren't for me figuring out how to access manual code entry, I wouldn't have spent money on this code.
How I accomplished bypassing the unlock app and getting a unlock prompt was by flashing AOKP and booting with a unauthorized SIM card, I'm just confused because what did that first successful unlock do? Why would it prompt me for the unlock code again and not accept the first successful code. I'm not sure if my device is unlocked or not at this point considering that, is it possible that the initial successful unlock enabled another band to be used in an unlocked state or even unlocked the device just the app does another step I'm failing to do manually to finalize this unlock.
I'd appreciate your opinions and advice in this situation, I personally feel like this might lead to something or either I'm running into a dead end another individual has also.
If you pay for it on like an installment plan you have to pay it off completely before you can unlock it. They keep it locked so you don't just do a promo and leave to someone like AT&T.

I'm not actually sure what the status of this device was, I bought it 3rd party from an Ebay seller. Any speculation on what the first "Unlock request successful" did if anything?
No idea unlocking phones isn't my specialty. But possibly the phone is blacklisted which is making it hard to unlock. Honestly what I'd do is take it to a T-Mobile store and ask them what's up.

Tried giving them a call, they appear to get very rude when they hear the word "unlock" which is sad, I take it they don't particularly care for people getting device unlocks? She hung up on me and the other agent just completely shut me off, she tried to offer me a contract but no further details which is really irritating.
That's unlike their service. It's possible you called at a bad time. More mid day is when they're as helpful as can be. I would take it to a store if possible and just tell them your situation I've done that before and they bent over backwards for me at my store.
Any news on this?

Unfortunately, nothing more. Still haven't managed to figure out exactly what it did, I did discover that the phone does not have money owed on it.. Not entirely sure what the chock this up to really. I cannot replicate the results to investigate with logcat, I know that my attempts didn't permanently lock my device thankfully.

OnePlus 8 T-Mobile Repair Nightmare

Figured I share my repair experience here as OnePlus has set a new low in my book for customer service. Started when I sent my device (unlocked by T-Mobile) for repair last month. I was given the option of repair or replacement but chose repair so I wouldn't have to unlock again. I received it back about a week later but with no documentation as what the repair was (found out through my calles it was a motherboard replacement. I did notice the SN was the same but the IMEI was different. Used it for 3 days and called T-Mobile to have it unlocked but their system now sees my device as a non-T-Mobile phone and they can't unlock it (and they have tried 4 times since Sept 25th). Over the past few weeks I have conferenced on T-Mobile support with OnePlus support in an attempt to get it unlocked and every time I call it's like starting from scratch with OnePlus. Four times now I've been told to wait 24-48 hours so they can hear back from there repair facility, I've made 14 total calls to check status (they have never called me back once). T-Mobile has been absolutely great and were on the phone with OnePlus with me for over an hour. So for know unless a miracle happens I'm stuck with a phone that can't be network unlocked by any carrier. Looks like the repair facility perhaps used a standard motherboard and flashed the T-Mobile firmware on it from what I can determine. If you need service for a T-Mobile device ALWAYS choose a replacement if you have the option)
Rule #1: Never ever choose repair when replace is an option. XDA is rife with people complaining about repair issues with every phone manufacturer. But I think you know that now. Also, I would hardly fault OnePlus in this situation. Its a simple issue of the IMEI not being in the T-Mobile database. Thats not OnePlus' fault. Thats a T-Mobile issue. IT can be added to there database. Verizon does this but for a completely different reason. But ultimately fault is in the eye of the beholder.
Also, to further support my claim think of it this way... T-Mobile (and Verizon) request the bootloader / SIM lock. If you buy the non carrier version from One Plus this would be a mute point. Again, a T-Mobile issue, not OnePlus. If you really want to get technical fault the US Congress for allowing them to lock in the first place. Ok Ok... Way off on a tangent...
Now... Some questions for you...
Have you ran the IMEI against an IMEI check database to see what kind of device it returns as? I would be curious to see. Another way to find out if its a T-Mobile device is to check the IMEI against your last phone. If the first few digits are the same or different will support your claim of the device being different.
Have you tried to tried to toggle the bootloader unlock switch or is it gray'ed out?
Have you tried popping in another carriers SIM just for giggles?
Lastly, have you tried to unlock it yourself by using the built in unlock program in network settings?
If that fails you may want to consider sending it back to OnePlus again for replacement. I can only assume that you do not have insurance? If you do then you may want to check with them about replacement faulting the IMEI as the issue. Might be a hard sell but I'm sure it could be done.

Same situation here, mine was unlocked did a replacement and it was locked and T-Mobile has no record of it. It took me 17 days to get the replacement and every day I checked the status I get told wait 24-48 hours. Now after I got it I'm told every day to wait 3-5 days for an update. Really one plus?
One plus sucks at anything customer service. Can you not do a warranty through tmobile?
Hi, i have the same problem. I was able to unlock my OP8 the moment I bought it. But after sending my OP8 for repair, it was locked when sent back. I got the error "server 255" when I tried to do a permanent unlock.
I contacted Tmobile and they said I need a valid tmobile account, which I don't:
"One of our mobile device unlock requirements is an active T-Mobile account. Since you don't have one you're going to need the get the unlock via a 3rd party company. Our apologies for this."
I have contacted OP 4 times now. They say they'll escalate my problem to the relevant team.
So how did u ppl solve it? Anyone tried the mtd below:

I hate oneplus with a passion I'm 8 months and still going with an issue they keep BS'n me on
Hi, I would like to post an update. After contacting OP support a few times thru chat, they agree to help me talk to Tmobile directly. I told them I can't use the phone, I'm overseas (really, no joke), and I contacted Tmobile but they refused to help.
After waiting for a few days, my IMEI is whitelisted and I was able to unlock the phone. So I guess if you are persistent enough and tell them tt you've exhausted your options, they will help. So I guess they're still nice ppl (kudos to Sophia!)
Hope someone with similar problem can try what I did.
Just wanted to fan the flames that OnePlus is still up to their BS. I sent my phone to repair the back glass after I recovered from unbricking my phone rooting after the Android 13 OTA. When I get it back, after all these warnings signs something was off I realized when I tried to put my unlock_code.bin and it kept failing that they gave me a new motherboard. Luckily I AM a Tmobile customer, but holy heck, what if I was not? Luckily somehow I was able to get in to get the info to request another code to unlock my bootloader even though I'm still carrier locked.

I just had my op8 repaired back with a motherboard replacement so that it can't unlock the sim as I am not a T mobile customer. I used online chat several times and complained about sim-unlock. Finally, after I gave them both old and new imei and strong complain, they unlocked my sim card. Not a good experience, but the result turned out to be good.
