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

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?

Lg Optimous 2X P999 unable to Unlock

I have LG Optimus 2X locked to Wind. My son installed the gingerbread software on it around six months ago. The phone works great. I tried to unlock it but I am unable to type in the code because no window pops up after inserting the sim card from a different provider. the phone goes to home screen. I typed in the numbers from instructions provided by the person. The message reads NO ACTIVE NETWORK AVAILABLE when the sim is from different provider but if I type in the same numbers when my active sim card is inserted the USSD code start running and after few seconds the message is IME code concealed. Thus I can not get the little window to type in the unlock code. Thanks for help in advance.

What are you typing to get to the dialog for entering the code? For P990, it is 2945#*990# (I know it works, as I used it myself), so I would think for P999 it would be 2945#*999#.
Keep in mind that the phone may not be able to accept the unlock code for several reasons (not sure about your phone, though). For example, too many unsuccessful attempts to enter an unlock code could lock the phone permanently. Or, the operator-branded firmware would not allow access to this function. Places that provide unlock services usually advise you to check in advance, before purchasing, whether you can actually enter an unlock code into your phone...

I think you need to be on a stock ROM to unlock the phone. Once done, it will remain unlocked and you can restore your previous ROM from a nandroid backup and try the other SIM card. Mind you, the P999 only gonna work in 3G either with Mobilicity or Vidéotron. With the rest of the carriers (Rogers, Fido) you will only get 2G connectivity.
In regards to Wind/other stock ROMs, nandroid backup/restore, etc check the P999 (aka G2X) dedicated thread. The phone is falsely advertised by Wind, it is not the Optimus 2X. The right thread for further information:

I think that i've unloked mine with flashing different baseband.
It was locked on my network but after flashing several roms and basebands it works with every sim.
Is that possible?
And when i flash some bb my sim is locked too.

I'm having the same problem as the OP. I have a Wind phone, but no matter what I try I can't get the unlock prompt screen to come up. I've tried 2945#*999# AND 2945#*990# with no luck.
But, I do have a Paranoid Android ROM on it. Maybe I have to revert back to stock.
Does anyone know where I can get the stock Wind ROM?

[Q] Help Unlocking rooted Exhibit with custom ROM

I'm trying to unlock the Exhibit 4G this week for use on a trip abroad (and yes, it is legal to do so since this was a prepaid phone paid in full in 2012 so T-Mobile did email me the unlock code - all that is good). What I don't understand is why it is not prompting for the Unlock code at boot. T-Mobile says I must have another company's SIM card in the phone to unlock the Phone. So, I bought a Simple Mobile SIM and placed it in the phone but it just boots up to the ROM as normal without asking for the unlock code. I am using the Linaro 4.2 rom (which is amazing btw!) but I also tried with Peach Sunrise 3.0 and Cyanogen 10 - nothing but a normal boot with no phone capabilities. So I have these questions: Do I actually need to pay for SimpleMobile service first to get the phone to recognize the SIM as different and ask to unlock? (seems unlikely) - Is Simple Mobile just not a good SIM to use for unlocking this phone... Or do I have to go back to stock ROM and unroot to unlock this? Of course if there are any other apps or shortcuts that will let me get straight to the unlock code prompt I'm all for it. Any help is greatly appreciated - not finding a lot of answers out there on the net and if it is on this forum I apologize for not finding it and would appreciate a link to it - Thx!

You probably need a different sim card. As I understand it, T-Mobile phones don't need to be unlocked to work on Simple Mobile.

Meekrawb is right, simple mobile uses the T-Mobile network.

To get your IMEI go to your cell phone and enter *#06# This will give you a string of numbers you will need to unlock your cell phone. Enter *#06# as if you are going to make a call. Then you will be given the string of numbers you will need.

After you obtain your IMEI and copy it on a piece of paper, power your cell phone off. Take the back off if you have a removable back. Take the SIM card out. Put a BLANK SIM card in its place. Power the cell phone on. A screen should come up asking for your IMEI number to be entered. It should look like a rectangular box. Enter you IMEI. There should be a small box under the rectanglar box that you press. The phone should then eventally unlock itself. You can test it by putting a different SIM card in your cell phone.

You need to get an unlock code.. It's not free to get one usually.. You can try calling the original carrier and ask them for the unlock code and they might give it to you or they may not in which case you'll need to buy one from a website but do some research on the websites first don't just pay the first one you see because some are cheaper than others and you can even use eBay..
