[Q] How do I unlock my phone? - Vibrant Q&A, Help & Troubleshooting

I've got the Gingerbread bootloader, Passion ICS, and I'm (obviously) rooted... Everything on here that I've searched said I should be unlocked, but when I gave the Vibrant to my AT&T bound friend, it doesn't detect her network (or even that the sim card is in the phone, for that matter.
The phone works fine with T-Mobile, and her sim card works alright in my G2X, but could someone clarify what's going on here?

If you call or email T-Mobile they should send you the unlock code.
There's other apps/hacks to unlock bit of a hassle but T-Mobile sent unlock for me quick. Bought phone used too, they don't seem to care much about T-Mobile account or not.

You see, my other AT&T friend had it while it was rooted with Trigger rom on it, and it worked fine for him. I'm thinking it's the bootloader that re-locked it, but I may not know what the hell I'm talking about.

Get "Galaxy s unlock" app by helroz from market. Works every time.

Still didn't work.
--Disregard. How do I check if it's unlocked? *#SIMLOCK# doesn't bring up anything.

Rooting, GB bootloader and ROMs, shoudl have no impact on whether or not you are unlocked, IIRC correctly. Use the Galaxy S Unlock from the market. Run it (correctly) and don't freak out about the black screen. It's only like that for less than a minute. Once it is done and rebooted, let your phone settle down.
Go into your dialer and punch in these *#7465625#
It will give 4 items. You want the top (Network Lock) to be OFF. If it is, then you are unlocked.
Don't rule out the fact that your friends ATT card might be bad or s/he might need a new one.

1. Yes, I have run said app correctly. The first time, I didn't have busybox, but I ran it again with it.
2. *#SIMLOCK# is the same as what you typed, it doesn't bring up the menu, though.
3. Her SIM isn't bad, if you read the OP, you'd know that it works in my G2X (what I didn't mention is that she has her own phone which it works in completely fine, as well.
Mostly, what I want to know now is why *#SIMLOCK# does nothing.

Strange. There is a manual way to unlock it using ADB, but it is pretty intricate with high probability of errors.
I would suggest just calling T-Mo and getting them to give you the unlock code, especially if the apps didn't work for you.
Let me know if you want me to give you the link to the manual way to unlock. Will take me some time to find b/c it isn't in the Vibrant forums at all.

I didn't say it didn't work. I don't have another company's sim to test it with, and *#7465625# doesn't bring up the menu, so I can't check it.

I must have missed that Disregard. Odd that the code won't bring up the menu, though. Do you still need to know if you are rooted though? If the Galaxy S Unlock worked (or even the fact that you could run it at all) then you are rooted. Did you grant it SU permission? If so, there is your answer.
Do you need anything else on this other than someone else's non-TMo sim card?

Go to network operators in settings. If AT&T is detected you should be unlocked.

Very strange. It shows that on the phone, but still doesn't get signal with her Sim card in. I'll research some more, and if any of you have theories, feel free to post them.

I didn't mean rooted xD sorry, I meant unlocked. It was 3AM and I still hadn't slept.

I have an idea. Maybe you need to set another set of APNs for ATT. Just a shot but Google ATTs apns and the go into settings>mobile network blah blah APN. Hit menu and add new, the put in what you Googled and don't forget to hit save. Back out and tick the ATT one and see if that works.
Worth a shot.

Thanks, I'll give that a try when I visit my friend again.

Thanks guys, it works now

Can you post your steps Please, I have the same situation and it does not work. I also have the Tmobile unlock code but their provided procedure was not work in ICS passion.

just fyi , I have the vibrant , no longer active on tmo , my worked changed to att , so i thought hell why not.
I rooted using superone click ,
I put the ATT sim card in ,
I dl'ed "Galaxy S Unlocker from market" by DaGentooBoy
I ran it and got error , dl'ed the "pro" version
I ran it and boom , worked like a charm , now phone works on ATT just fine.
I hope that helps someone
tried other methods first , but kept getting permission errors

While you had tried to find out , was simcard in your phone? so this one Galaxy S Unlocker from market worked for you?
thanks

[Q] Phone permanently locked

I bought an E970 on Ebay and when I tried to unlock the phone it did not accept the code. I used the code 2945 # * 970 # to enter in the SIM Unlock Process, and on the Network Lock option it says "this phone is permanently locked and can not be unlocked". Is there any way to reset this setting? Can I use a box to remove this setting, or reset the counters? Thank you
I contacted LG and they told me that only AT&T can restore the phone. Is that true?
Does anyone know how to resolve this?
Sounds like a SIM lock, meaning an unlock code was typed in like 6 times wrongly.... I am pretty sure it is just locked at that point. OR it is stolen..

I don't know much about this but I don't think that's true. SIM unlocking the phone doesn't happen over the networks so AT&T, other than having the correct code, doesn't have much to do with it. Also, nothing is permanent on the phone other than /system which requires root to change. I think you could solve your issue by factory resetting the phone. That should clear out what ever file or app is saying you are permanently blocked after incorrectly entering a code.
You could also try clearing data for certain apps that have to do with the SIM card and phone app. But I have no idea which ones and it could cause problems.
EDIT: I saw whoamanwtf's post. I have had my phone sim locked before and yes contacting the original carrier will get you the code. I thought you were talking about sim/network unlocking.

I am talking about SIM/network unlocking.
I bought the E970 while in the US, but I live overseas in Europe. I used the phone in the US with a AT&T Sim card, when I returned to my country in Europe I tried to unblock the phone so I could use it with Vodafone, but the code didn't work. The phone is already rooted and have the bootloader unblock all by me.
That's when I used the code 2945 # * 970 # to enter in the SIM Unlock Process, and on the Network Lock option it says "this phone is permanently locked and can not be unlocked".
The previous owner must have tried to unblock the phone using Internet codes, you can only insert 10 wrong codes, before the cellphone locks itself for good, meaning it stays blocked to AT&T. My question is does anyone know how to remove the setting of permanent locking? The phone works fine, but I cant change the SIM card to my carrier, it won't accept the SIM.
I was told that those kind of setting are in a different part of the phone, in dedicated chips and you need to use special tools like the SE tool box, or the Z3X box. But none of those boxes currently support this phone.
Does anyone know more about this? I really need to use the phone and I can't because my Vodafone SIM card is not accepted.
Would installing a custom ROM reset everything so you could try unlocking again?

This is just guessing, but no, I don't believe so.
This isn't a ROM issue.
The only thing that I can think of that MIGHT work is lgnpst... or maybe even the n4 conversion and then back to the stock OG.
The only reason I think that may work is it completely overwrites some partitions that are otherwise untouched by recovery/flashing/etc.
Mind you, the process is really dangerous and not supported by most of the devs (including those who pioneered it).
OP - either try and sell it for ~$100 and get another one... or try those methods since it doesn't do you much good atm.
Or go to the irc channel and see if the much much (much much much) more knowledgeable people in there know a fix.

Where can I find the lgnpst?
Usually this kinda of problems can be solved using dedicated hardware/software, such as service and repair tools.
I'm sure LG have them, since they're the ones who made the phone, so it's a matter of time until someone makes a commercial repair tool.
I just need to know if someone as ever tried to read/write or at least located the EEPROM with the hard network lock.

You'll have to use the links here to get them from IRC, it is not allowed to be posted on XDA.
(I would ask somebody in there if it is even possible).
LINK.
But again, Idk if that will do the trick or not, it is the best chance though.
Does anyone ever tried to find were the phone saves the information about the sim card? Or about the carrier?
Maybe it's possible to fool the system.
Does anyone know where the information is written?
Does the phone uses a separate chip or is it in the internal memory?
Sorry about all the questions, I just want to understand why the sim lock can't be removed.
If AT&T can remove the lock, it's just a manner of finding were that information is.
The phone searches for the sim card only after booting, right?

LGNPST it and see if it fixes it. or like Bleached said, do the LGOG conversion then fastboot erase everything.

I believe I read that there are some partitions the conversion leaves intact.
So since you have to go the irc anyways to get lgnpst, I would ask them there if that would even fix your issue. If it won't they can save you from performing a few hours work and risky hacks.

I flashed the original AT&T ROM using lgnpst and it's the same.
From the experience I have from old phones (especially Nokias) the permanent lock is written on a special chip.
Normally you need to use special software/hardware like the Z3X-Box or SE Tool Box.
They can repair almost everything on a phone, but right now they don't support the LGOG. I think it's because they're from Europe and E970 is America only.
Anyway I'm going to send the phone to America, maybe the guys at AT&T can repair the phone. But I have my doubts since I purchased the phone on Ebay and don't have any type of receipt. And if you permanently block your phone that's normally your fault, so they refuse to repair.
One thing you could try add a last ditch is to pull the battery by opening the case. Then factory reset and start over by root freegee.

[Q] Using P769BK with Net10

Is it possible to do the adb reboot oem-unlock using a sim card that is not from T-Mobile? As I said in the title I am using Net 10 and I'll leave the phone plugged in all night and I still don't get the menu.
I also tried calling T-Mobile and they said they won't give me the unlock code since I did not purchase from them and am not using their service. I also tried LG and they said no since I could damage the phone.
So you want to unlock the bootloader, or the simlock? Sorry, dont quite get it...
Sent from my LG-P760 using xda app-developers app
Try getting the code from Net10. As long as you have a SIM that registers to a cell network and has internet access the bootloader should unlock. If you don't have internet on your plan try leaving wifi connected. Don't forget to set wifi to always stay connected in wifi settings.

ohh... I had seen that about leaving the WiFi always on, but it never registered. I do have a data plan with them.
So, is it the same procedure, I give Net10 the IMEI and they give me a code?
Does it matter that it is not a TMobile sim? I've seen scattered reports of other users having issues, but they seem to give little details. I am not sure what is enough to give. I tried a logcat but have nothing from that. I also just did the OTA of V20F, I am going to go back down to V20D before doing the unlock to see if that makes a difference.

You need to have the Euro P760 ROM. That is the only one that works if you want to unlock the bootloader.

Changing carrier and phone not working with new SIM

I have been using ATT service on this i777, now going to China and will be using their carrier for a long time. I learnt I have to go to either China Mobile or China Unicom if I'm to stick with this device. However both carrier's SIMs resulted in "SIM card not provisioned" notice and it's not working.
I am wondering if calling ATT helps, or I need a SIM unlock code, or I have to install a custom ROM to somehow bypass the SIM check? Or even more? I love this phone so I don't want to buy a new one here in China.
Any help is greatly appreciated!!

Your phone needs to be sim unlocked. If it is not unlocked already, then by far the easiest route is to call AT&T to get the unlock code.
oh I'm sorry, I think I already unlocked it (spent a few bucks and got the code on a website)
I put in China Mobile's SIM and entered the code in the prompt box. Do I still need an unlock code from ATT ?

Thanks for the reply. I replied you above but didn't quote.
If the phone is already sim unlocked, then you don't need to unlock it again.
I've never gone through the unlock process, or traveled over seas, so I'm not the best person to answer your questions. I think "not provisioned' indicates that the sim is not activated, or that the phone is not set up for the network, or something like that. You may need to input the correct apn for the network. Maybe you could go to the carrier's store and find someone who could help you?
Maybe someone with experience will jump in and help.

Tethering Issues With WiFi on Straight Talk

I am on Straight Talk with this phone and I have been running the TrevE Mod WiFi tether and PDAnet tether app on all my phones and they work fine...This is my only GSM phone and both tethering apps show that there is a connection but no internet access....and yes I have and internet connection on my phone.
With the TrevE WiFi tether it says on my laptop that it is "connected" with great signal strength but no "internet access".
On PDAnet, I tether using USB and it says its connected but when I open my browser and type something in it tell me "cannot find the server"
If anyone else is using Straight Talk and can tether with this device please let me know how you did it..
My device is Rooted with Elegancia Rom.
If you just want to tether in general, I use wifi_tether_v3_3-beta2 and it works fine with straight talk. But I'm not doing usb tether so can't say how it works for that. At any rate, maybe give it a look and see if it helps.

I'm running Elegancia Rom, in your opinion would that have anything to do with it, I don't think so myself. I'd like to run something by you and ask for your feedback on it....I got the unlock code for my phone from At&t and they said when I put the ST sim card in it I would be prompted to put in the code but that never happened, I never had to put in the code, I just put in the card and it worked....I asked ST and they said if I had internet on the phone it was unlocked...Do you think that might have something to do with it or maybe even the new sim cards they have, I wonder if getting to old ST sim card from Ebay might get around the block...
BTW, thanks for entertaining my questions.

From what I understand, Elegancia should already have the fix to make the tethering work built in, plus he's been pretty thorough about testing and maintaining the rom so I wouldn't think that's the issue unless it's marked on his known issues list. For the sim question, I've found that the sims from straight talk are somehow branded, so if you put an at&t st sim in an at&t phone it doesn't actually need to be unlocked because the phone thinks it's an at&t sim(at any rate back when I was on T-Mobile that was how it worked for me). So my first guess would be that it's not unlocked and that's why you never saw the code request. I would not think that had anything to do with it unless you were on a stock rom. The stock rom will tell you to dial 611 and upgrade you data or something like that, but again, elegancia is supposed to have already patched that is my understanding. And technically I guess it is working, it just isn't working correctly. That's why you have tethering, but no net access...this may be a silly question, but did you configure the new connection properly on your pc? I know on mine(win7 64bit) it asked me again if it was a home/work/public network and I had to choose home,etc again before it worked(otherwise it gave me the same issue you're getting). You probably already checked that, but thought it might be worth mentioning just in case.

Thats some great feedback, thanks....I did choose Home when it asked about the network. I will try taking out my ST sim and calling At&t about the unlock again. I have the code but I will see if they can unlock it themselves....Man I hope I get this working, I'd love to be able to tether with 4g...

I don't know if it was the flashed rom, maybe I should have used the stock rom. I will try a device reset to see if it will go back to Att settings and push a stock rom and reinstall the ST sim and see what happens. :crying:
When you got the unlock code from At&t and put the ST sim in, did you get a window to input the unlock code?
Please tell me how you unlocked your device. I never got an unlock window. Plz message me with details if you need to....thanks..

Well, I went a slightly different route. I buy all my phones myself and have for a long time, so I got mine off ebay long before at&t was even willing to give out the codes on it. So I paid an online place to get my code and send it to me. Once I got it I inserted a TMobile sim into the phone and it asked me for the unlock code, which I then entered. I know on some phones there is a numerical code you can enter in the dialer to bring up the sim unlock option, but I don't recall what it is...

I was thinking about getting one of those "original" ST sim cards but decided to go with the ones they offer on their site. I read that if the sim doesn't have the unlock code script built in it won't ask for one and since its "At&t compatable I bet thats what they did). I guess I'll try and get one of the original ones....great, more money...LOL. Thanks for the info.

UPDATE: I used a Verizon sim for a sec and got the unlock notice to unlock my phone. I got it unlocked and thought that would fix my tethering problems but it didn't. I just don't know what else to do...HELP
My guess is you have the LTE tfdata SIM and that is why tethering does not work. Tethering connects but you get the "no internet access".
gokun , your tethering works but what SIM card do u have and what's ur apn setting? Tfdata or att.mvno?
I posted a reply to this thread and it appears to be gone. Did I do something wrong?
If it helps, I have Straight Talk and am using a jailbroken iPhone, running MyWi 5.5. Tethering worked fine up until a couple months ago, at which point I could connect to the Phone just fine via WiFi, but not access internet.
Found out that MyWi uses Google's DNS server (8.8.8.8), and apparently Straight Talk is blocking the connection. If you I access websites using IP address, then it works fine.
Might be something to experiment with and see if the software can provide a work-around.
I also have the same problem. Running an unlocked and rooted galaxy s2 and treve mod. Worked great with tmobile, switched over to straight talk and it immediately stopped working.

johnnylingo, that was my problem. Thanks for posting the solution. Straight Talk is blocking DNS server 8.8.8.8.
Changing the DNS server from 8.8.8.8 to "only" 8.8.4.4 worked for me.

[Q] Galaxy S2 Won't Register on Netowrk

Hi all,
I'll explain my situation. I had a work supplied HTC Sensation. The most god-awful handset known to mankind... except the iPhone. I digress. We are on Vodafone UK. When it came to renewing the work phones I was given an "upgrade" iPhone 5s. Long story short, I'm not using it. I have a Samsung Galaxy S2 which was on T-Mobile. I was given it and I thought I'd give it a go as it has to be better than the HTC Sensation.
Firstly I put in my Vodafone SIM. As I expected it didn't work. I have checked the IMEI number and it hasn't been blacklisted. So I thought I'd unlock the phone and root it. I followed the advice in this thread:
http://forum.xda-developers.com/showthread.php?t=2365701
After the first go of installing Jellybean which is what was on there initially I got to the end, rooted it and it wouldn't unlock using the method given. The method goes on to say that it works with ICS. So, I went through it again and installed ICS. Rooted it. Ran the unlock. Still locked.
Question 1: Is SIM lock the same thing as Network Lock?
At the moment, I have the stock ROM from the above thread for ICS installed. 4.0.3 I think it is. If I put my Vodafone UK SIM in this phone, when I try to make a call it says "Not registered on network". Tried following lots of advice in different threads. None worked. I thought, maybe that it can't register on the network as I am boosting my signal through a Sure Signal. I tried going to a place where I know I would normally get signal and tried doing it there. Still no luck. I keep digging and I come across the DEBUG MENU on the device:
http://forum.xda-developers.com/showthread.php?t=1882796&page=4
It suggests this:
dial "*#197328640#" to enter debug menu
click "6 [common]"
click "6 [nv rebuild]"
click "2 [erases three partition!]"
Except in the 3rd option there is no menu option 2. I have kept digging and then came across the "Personalizatiob Status" (http://forum.xda-developers.com/showthread.php?t=740167) and it shows this:
Network Lock
[OFF]
Network Subnet Lock
[OFF]
SP Lock
[OFF]
CP Lock
[OFF]
Please note that during all this my Vodafone SIM is NOT in this phone. It is in the HTC Sensation and is working just fine.
Question 2: Do I have to have my SIM in the phone when I do all this?
Question 3: How can I get this phone to register on the network with my existing Vodafone UK SIM that is working just fine?
I've tried the Galaxy S2 Unlock apps on the market store. The unlock code and unfreeze code show gibberish.
What am I missing? I don't actually care for using the stock Samsung ROMs because the phone is way out of warranty anyway. I just want to avoid having to use the iPhone I've been given.
Any advice welcome.
Any advice from anyone?
Cheers.

If you dont know what it is; then one would presume you havent tried it.
You can do a google or xda search, or charge up the iphone.........

Nope, haven't tried that one. I will give it a go later on this evening. I've tried a couple of unlockers that have been recommended in other threads and neither have worked. I'll keep you posted.
Any thoughts on the other questions I had on the original post?
With regards to the iPhone, I think I'd rather stick with the HTC Sensation despite its multiple daily crashes/restarts and almost constant need for recharging.
I tried the app and it said everything was unlocked except for CSC Lock. Now, I did some reading on that lock and that seems to be a geographic lock applied by Samsung. As this phone was bought in the UK and I'm putting a UK sim in it, then this won't affect me because both the original TMobile SIM and my Vodafone SIM are UK.
It said my unlock code was 00000000. I doubt it is that, but on the slim chance it is, where do I even put the unlock code in?
Attached is a screenshot of the lock status from GalaxSim by Spocky.
It now shows everything is unlocked. Any ideas?
I can see the sim operator is listed as Vodafone and the registered operator is O2 according to that. Weird as it had a working T-Mobile sim in it prior to my getting it.
Thanks.
Any further ideas? There has to be something I've missed.
Well, I have still not managed to find out why this phone won't connect to the network. Sadly my old HTC Sensation has pretty much now become unusable and I've had no choice but to start using the iPhone provided by my work as I've not been successful in getting the S2 up and running.
I cannot believe just how bad the iPhone is. I've always said they were rubbish from day one despite having never owned one. Now I have one, I can justifiably say that I was correct in that they are dreadful things, however, I didn't quite realise just how rubbish they really are. Now I know.
