SIM network lock after reflashing of JM5

Dear all,
I need help!I have an unbranded Galaxy S and I usually update the firmware without any problem(until now!!). Few days ago I flashed for the first time JM5 firmware without any problem. Today I had to reflash the JM5 firmware. Everything was ok but when I booted my phone I had the message: "SIM network unlock PIN"!!!!I'm going crazy because I cannot unlock the SIM!!!What's happened? Please help me!!I tried to reflash with an old firmware but no chance to reset!!How can I proceed?
Thank you

Contact your operator for your PIN code, unless you have it in the letter that you got with your SIM card.
EDIT:
Actually: Did you buy the device from Handtec?
According to this thread, they got a batch of Orange-locked phones where they should've been unlocked.
Return the device to them to get a new unlocked one.

The problem is that the phone worked properly without any restriction for 20 days with the same SIM and now I noticed this problem!!!
I cannot also unlock my phone via websites that provide this kind of codes because I don't really know also the name of the opeator that is locking my phone!!
I think that this is an internal problem of phone but I don't know how to fix it.
Other ideas?

What on Earth, same issue here.
My phone just randomly got locked.

What do you mean? Do you mean that sometimes you are able to use your phone e sometimes no? How do you unlock your your phone?

I think that you have an imported device that was unlocked from the seller. When you have restored the factory settings, probably the unlock was... wiped... I have had the same problem after a factory reset; I'm Italian and my Galaxy is an imported item from Hungary or Austria, but I don't know the original provider that locked the device. I have phoned the Samsung Customer Care (the seller is on vacation until the end of august ) and, from the IMEI, they told me only that the device was producted for the Austrian market. Without the provider it's no easy to unlock the phone, but there is a service that I'm trying: unlocksamsung.co.uk - they are partner of Mobileunlocked.co.uk, but unlock only samsung and only using the IMEI number of the phone. In the meanwhile I've ordered a I-Smartsim 2008 from Ebay...
Bye.

Did you try reflashing a different firmware?

All from JF1 to JM5.

so that means the lock in the firmware ? I was under the impression that is was not.

No, the network lock is firmware independent. I was able to flash various firmware without problems in first days. The lock appeared after the first Factory Reset using the vol-up+home+power combo.

I can confirm that the network lock is firmware independent, however my phone went into network lock before Factory Reset.
I did however try Factory Reset to fix it and it didn't help, nor did flashing several other roms, including the stock rom.
I contacted the point of sale and apparently they had a previous issue with a batch of phones but they did not expect it to happen again.
I hope if a replacement isn't honoured then we need to find a solution... :\

Once it showed up I haven't been able to use my phone as a phone.
When you enter your SIM PIN (if you have one), it then jumps to a full screen that asks for a NETWORK UNLOCK PIN.
Just to clarify, this is not PUK or PUK2, as I can use my sim in another phone just fine. ( G1 actually. )
Did you buy your phone from handtec? If so your phone is probably locked to Orange UK.

I don't know. I'm Italian, I bought it as an import "free" device and maybe the phone is from Austria or Hungary. I hope in a software workaround in the future. For now I'm waiting (and hoping in) an unlock code and/or the unlock sim buyed on ebay (till seller reopen at the end of the month...).
Bye.

Just to understand what this issue is about: now, when your phone is trying to connect to the Network, it checks your device's IMEI as "locked" and then negotiate a PIN Dialog?

Now that is REALLY scary.. Can you please try to remember what you did, or what program were you using -->right before<-- the network lock got restored ???! Something must have made the Factory Reset trigger...

Same thing happened to me 2 days ago. I removed the sim from my phone and I left it without battery for ~16hours. When I put the sim back, I got the same message to enter SIM network unlock PIN.
Fortunately for me, my phone was unlocked via an unlocking service and I had the NCK code. The trick is that I cannot unlock the phone again using this code, but I can lock it to my network with it.
The weird thing is that now I can use my phone both on the network that it was previously locked and on the network that i locked it. So, my phone is now locked on 2 networks And the other thing is: I can enter as many unlock codes that I want. it is no more limited to 3 tries.

Tell me, have you unlocked it after you bought it?

rbnet.it, let me try to clear things out and understand it:
A - Wasn't your phone dead?
B - What program did you use to check your locks?
Also i'd like to leave some general question for anyone who knows:
C - Do you think that if a galaxy S user unlocks its phone online using some kind of site, the phone will eventually lock himself up again?
D - Are the locks "predictable"? I mean, will the phone always do Network-Lock or always do Sim-Lock?
This scares me out a lot, my phone is locked to "TMN" (network only) but everything is OK as long as it stays that way... But i'm starting to believe that it won't

A: No, it isn't dead It's network-locked on a foreign countries/provider: I can't use the phone section (call, mobile networks, etc) within Italian providers, but if I dismiss the pin request (or leave out the SIM), I can use any other functions.
B: a samsung code that check the status of the phone: http://ip208-100-42-21.static.xda-developers.com/showthread.php?t=721111

Good news guys.
I contacted Handtec ( Place of purchase. ) and apparently it's a issue with Samsung Firmware or something.
The guy sent me a network unlock code, and it seems to work.
I haven't got the prompt again.

That's just what I was wishing for =)
Since yaz00us told us that his phone locked himself up, it had to be a Samsung Bug.
By the way, does the given code work for future times? If so i might ask mine right away... =)
thanks for the good news

Have you tried the app found in the market? (you need the original Sim card from where you got the phone and any other company's sim card
Try searching for "SGS unlock" in market place. It should be called the "Samsung Galaxy S Unlock Tool".
Simply Run the app after installing (while using the original Sim card) and it should give you two codes: an unlock code and an unfreeze code.
Once you get them, I suggest writing it down and/or emailing it to yourself.
After that, turn off your phone and swap the sim card to the one you want to use. The phone "should" ask you for the unlock code when you turn it back on and after it has booted. Simply enter the unlock code and you phone should then tell you it's unlocked (if everything works ok otherwise it will say it was unsuccessful).
Note: I am on Bell in Vancouver running the stock 2.1 firmware and it's worked fine for me. There have been people who were not so lucky and it did not work for them. There are even those who have gotten their phone locked due to trying to many time when after it fails to unlock, but that is what the unfreeze code is for. If you're with Orange mobility, I've read that some of their phones were already unlocked. You could always just try a different sim card and see if it accepts it if you haven't done so already.
Hope this helps.

Thanks for replying, new to this site not sure what I'm doing !
When i paid to have the phone unlocked i had already canceled my o2 monthly contract so the phone had no Sim in it when being unlocked, i don't have the o2 Sim anymore, i brought the phone from o2 so they might help me out I'll have to ask them. I've just put a o2 pay as you go Sim in the phone & it didn't ask for the Sim Network Unlock Pin but with the 3 contract Sim it does ask. I have installed the SGS Unlock tool but i haven't run the app. I'm having the phone unlocked again tomorrow so he hopefully can sort it out. Thanks again.

I tried to "SGS unlock tool" and nothing does not give me the codes. When I go to the root gene codes told me: "Sorry, no codes found. File not found: Do you have S Business"
I have no idea what to do.
Is there some other way to decode or knows someone why this is happening?
I also tried with Generate Unlock Windows, error is: can not find nv_data.bin

Help trying to unlock verizon xt862

Hi guys, noob here, but not so noob on android OS
I was trying to unlock my verizon droid 3. And when I´d inserted a sim from another carrier, it just says "subsidy lock, call provider".
How can I make the phone ask for the unlock code?
I read somewhere that this message appears when you tried too many codes, but havent tried anything. I read that this problem was solved on other moto phones by leaving the phone idle at subsidy lock screen for 4-5hs and the phone will ask again for unlock code, but thats not the case
Anyone experienced this problem?

call verizon tell them your going our of country on a business trip and you have a european SIM already that you would like to use, but you need to unlock your phone. viola

Im already outside US. Problem is phone dont ask for unlock code.

Alltel or Verizon Wireless do not use any type of subsidy locks on their CDMA phones. Default Code:000000 or 123456 or 654321
that is what i found by looking up the subsidy lock error you described. tell me what happens when you input one of these. im still doing more research for you

Hi, it just says "subsidy locked" and a discard dialog box, there is no box to enter any number
Phone is dual cdma/ gsm 3g, Im trying to unlock the sim part.
I´d read this forum.xda-developers.com/showthread.php?t=1406812 but Im missing the enter code dialog box

the fact that their is no dialog box is weird to me. can you press the menu key? does anything pop up? i googled this but did not find anything. ima check some other sites. do you have an account with verizon?

Yes, phone was working on verizon till the day I leave my city.
The only option when I put a foreign sim card... it´s just the subsidy lock legend and if I hit the discard dialog box, phone goes to android home menu. But obviously with no gsm signal.
I can do everything, flash, root, everything. The only thin I cant do, it´s downgrade, phone was updated to last verizon 2.3.4 OTA when was connected to verizon network, and as other thread says, it´s no downgradeable atm. Im thinking that verizon could have put some newer simlock protection to latest updates...

since subsidy lock is simply by the carrier you can contact verizon and they can tell you what to do. if you dont have anyway to call the usa, you should email them.

Well... more news. Contacted verizon tech service and they teach me how to get to the unlock screen. But for the code I have to wait almost 6 more months.. lmao

Well... more news. Contacted verizon tech service and they teach me how to get to the unlock screen. But for the code I have to wait almost 6 more months.. lmao
At least I can try any code now

sorry you have to wait. i should have said there is a certain wait period for each person [i think 10 months] before their eligible for an unlock code. butttt you can always get one online. glad your initial problem was solved though

Yep, thanks for helping. Maybe Ill try some online code but I think they wont work
If anyone is experiencing the same problem, the only way to get the unlock code input screen is setting to only gsm mode and then turn on/off airplane mode a couple of times and magically unlock dialog box will appear.

there is one that works. ima go find which forum i found it in and post back tonight. probably within the hour. well i cant personally garuntee it works but it had good reviews from xda memebers

That would be nice In case you dont want to post link here, just send me a pm

I have to do some things for the rest of the night and its too much too look up on my phone. If I don't get on again tonight I always check xda whe n I wake up so ill have it first thing tomorrow morning at the latest
Sent from ICS Droid3 using xda premium

Maybe share what you did to get the unlock code dialogue to open. Save others the time of having to call Verizon themselves, since you already did that
Why do you have to wait six months? Was your line on Verizon too new to get an unlock code?
Droid 3 with stock xt862 ROM working on T-Mobile via xt883 radio.img & custom build.prop

Yep, first rule on a forum: dont say it works, say how you make it work
Its a couple of post above, set only gsm mode, turn on off airplane mode a couple of times, and unlock dialog will appear.
I'd unlocked other phone some time ago on verizon and for the next one, I have to wait half a year
Anyway Im not coming back to states anytime soon, so I'll have to throw it through a window
Btw fisrt ebay code didnt worked.

My bad, didn't see this whole second page when I was on mobile lol. Second rule on a forum: read all posts! Good luck.

ebay switftunlock freedomobile and unlock_fusion
whichever you choose and they can send you and unlock code. these are based on reviews from this forum

Thanks, I´ll try one of them

Weired unlocking prob P990

Hello I just bought a LG optmius 2X from fido and i have went out and got an unlock code ( yes i made sure i had the correct iemi number) BUT here is what happend
I went to the dialer typed in 2945#*990# brings the unlock panel so i begin typing my code the first one went quickly and the phone quickly restarted so i thought yay i did it so i threw in a rogers sim but to my suprise nothing happend.. so i tryed again with a bell sim and once again nothing happend so now i was checking the imei number and that matches with the unlock codes so i have no clue what im doing wrong as well i tryed all the other codes that i was sent with no luck as well
what am i to do?
PS When booted up it says NO SIM as well i have NEVER had a accutal fido sim card in the phone as well i have updated to android 2.3 and that effected nothing

207 views yet no help

If you're not getting replies it's because nobody that has seen this yet knows how to help (me included).
In my case it was quite simple as the companies over here are forced to give the unlock codes, all I did was put a SIM from a company other than what I had (as said on the instructions) and then bring the unlock menu and enter the code.
Don't know if using a different SIM before unlocking is necessary because of the model itself or just the company I was using, it wouldn't hurt trying that way so put another sim first and then bring the unlock panel.

Thank you very much for the reply. I have tryed two other sim cards. both givethe same result now isthere a way to check if the phone is ulocked not buy puting in an new sim? Also the phone has never had a fido sim in it could this cause problems?

The easiest way to check is using a non accepted sim card and getting network. I don't think never have used a fido sim is the issue.
I just want to be sure you're doing the steps right,
1.- Insert a non accepted sim and start the phone, when the phone has loaded you should see the message "locked network/sim" (don't know exactly what it says in english)
2.- Dial the sequence 2945#*990# or 2945#*999# and then input the unlock code, you should get a message saying the request to unlock the phone was successful (again, or something like that) and then the phone will restart
3.- Once it loads again, you should see the name of the network provider and have signal.
Now try again, and tell exactly where it's going different for you to see if someone can help you, if not there's always the option to unlock by software.

Thank you but i get an error when i send the unlock code says networking error of.somthing also is softweare unlocking easy to do?

Network Unlock issues..

Ok so first off I've searched and its how I got up to this point.
In a nutshell: Im from Puerto Rico, have a Ace S5830L on my hands, did the BLM5 method to get network unlock key, box didnt appear so had to upgrade from 2.2.1 to 2.3.4. Put the code in, unlocked the phone. When I do the *#7465625# all locks are [OFF] but when I put in a T-Mobile SIM(the phone is Claro) I get a message saying (No Service) | Network Lock and I get a new box saying to insert Network Lock Control Key.
So question is...what the he-- is this Network Lock Control key? What do I have to do to get the Tmo sim working when the phone is apparently unlocked already.
Thanks

bump...
sorry for the bump guys its just that I've been searching pretty much for like 12hrs now, here and on htcmania, which some people recommended but I cant find any definite answer, the questions been asked by others but I see no response and those people havent posted any solutions either. Again...thanks for taking the time to read the thread. Hope to hear from someone.

Some stock firmwares, even unlocked, have problems (telcel in mexico, for example). Have you tried with a free (unbranded) firmware or any custom rom?

I havent tried any custom roms, but I am running the unbranded KP7 stock 2.3.4 rom.

youre right, my apoligies.
Yea I checked the imei and its still there, didnt get deleted. I also read that supposedly some companies do a double lock which is what the Network lock control key thing is. Any chance this is true? If so, any way around it?
