[Q] 2nd level SIM locking ? - Galaxy Note II Q&A, Help & Troubleshooting

Hello,
Hope the title sounds english enough !
Well, since I've changed my phone carrier, I face a lock issue.
First of all, I thought of the SIM locking, so it tried almost every way of Galaxy to remove this lock (downgrade to a 4.1.1 ROM to perform the *#197328640# trick, for example), faced some issues (loss of IMEI... thanks again, Dr Ketan !) but, lately I found out that GalaxSim Unlock app reveals that my phone is unlocked. So I contacted the developper that told me about a second blocking system that Sammy would have implemented on its latest devices / softwares.
Has anyone of you heard of that ? If so, is there a way to get rid of it ??
The device still ask me for unblocking code at every startup and displays, in the notif barr, "SIM card not valid" (the SIM has been activated by my new carrier).

Samsung i780 SIM CID unlock?

Hello,
Is there any software around to SIM and CID unlock this amazing phone?
thanks,
Joao Oliveira!!
Hi Joao
I'm expecting my i780 to arrive end of this week and am also looking for a SIM unlock- unfortunately it doesn't seem like there is one around - even finding a website where you pay to unlock is difficult!
However, someone on Modaco unlocked his Orange i780 using a pay website:
http://www.modaco.com/content-page/264705/I780-Locked-GPS/page/40/
Alternatively, perhaps flashing the ROM will work? Must admit that I'm not going to try this method yet as posted on the thread....
How much is your network charging for the unlock?

Hello,
Thank for you response.
Any news on unlocking this device? have you tried flashing a new rom? did it work? to be honest i am very scared of flashing a new rom on a locked device, i dont want to brick it.
My network charges me 130euros for unlocking the device. Not too much since i paid very little for it but still ...
Thanks.
Joao Oliveira.
Hi - yes in the end I paid £19 to get it sim unlocked on the day that I got the phone as at the time there was only a test pda rom I think.
Anyway, my sim worked fine once I unlocked the phone but I couldn't get the GPS to work. I think the italian splitted radio rom was available after that so I tried flashing that - it didn't help the GPS, and in the end I had to flash the pda as well (the MSHC3 rom).
Now everything is working thanks to the guys here.
EUR130 is a lot of money to pay to get your phone unlocked....

Understanding how network/sim lock works need help

Hello,
I just bought a new desire from an auction site like ebay, seller saying it is locked to Vodafone; I bought it since I have a sim card from Vodafone Romania and assumed stupidly that will work.
The phone seems to be from Vodafone Malta. I am saying this since there is a desktop shortcut on the phone desktop leading to the Vodafone website in Malta.
I called Vodafone in Romania and they provided the PUK code for my SIM card, but it didnt do the trick.
I got a code from one of the sites mentioned by many and it didnt work.
Then I went ahead and rooted the phone...got the gold card created, etc etc and in the end installed a new ROM (version 3.1 from MoDaCo). Even now the phone is still locked, hence I believe is something that I do not understand in terms of how phones can be locked by various operators.
Would really appreciate if somebody can help me understand how is this working?
As options, should I use a different baseband then, etc? I am a bit lost since I thought that if I am flashing the phone and install a new "neverlocked" ROM version then it will be fine. Or maybe try to flash the Vodafone UK original RUU file and then try again with the IMEI based codes as it seems like there are people getting unlocked for Vodafone in UK?
My current system looks like this:
- firmware: 2.1-update1
- baseband: 32.36.0028U_4.06.00.02_2
- kernel: 2.6.29-bravo-mck-r1
- build: 1.21.MCR.2
- software: MoDaCo custom ROM r3.1
Any clue on what is triggering the network/sim lock out of those elements? or nothing to do with this approach? What is the "part" of my phone that needs to unlock the sim card and connect to the network (maybe I can change that so it is able to connect to Vodafone Romania at least)
Thanks!
As far as I am aware the Network lock is independent of the firmware and as such this will have no effect on the lock status. The only way to unlock phones is with either the official code or a vulnerability in the firmware (as discovered in the iphone).
I have unlocked a load of iphones but when it came to the old motorola v50 I had to pay £5 to http://www.fonefunshop.co.uk/ for the code. I can only say that their codes worked for me and that there are many scam sites out there when it comes to unlocking, so maybe the first ones you tried for a code were not genuine.
Hope this helps
James
What happen though if one doesnt know what is the network that the phone is locked to? I was let's say lucky to assume that it is Vodafone Malta as there was this link on the phone's desktop.
Actually my question is more around how to unlock the phone with little or no dependency on the network where the phone is locked.
I red some articles that in some cases there is a big play for the baseband as this can "dictate" the way the phone is connecting to the network, however I am just starting to look into that and it might take some time, hence more opinions are very much welcomed.
Thanks!
If I was you I would try flashing the roms as posted earlier but if you can wait then I would email HTC with the IMEI and ask who it is locked too.
Thanks so much for the suggestion with contacting HTC for telling me where is it locked...not sure if they would know this based on the IMEI, but will give it a try for sure. The thing is that I already flashed the ROM and it is still locked, or maybe I missed your point on flashing the ROMs.
No I think you are right that the flashing wont help with a lock problem but HTC Should know who they locked their phones too. I could be wrong but I think HTC do all the programming pre shipment. If anyone knows different I am happy to be corrected?
Coming back with HTC's reply to my question about where is the phone locked (provided my IMEI)
Here is the answer:
"Dear Mr.Popescu, Thank you for contacting HTC. Kindly note that your device is not SIM locked and is not network branded. Your device is manufactured for Czech Republic and is HTC branded. S/N:HT05XPL08419 IMEI:xxxxxxxx. If you have any other inquiries, don’t hesitate to contact us again."
Funny part is that my phone looks to be branded by Vodafone Malta (just the soft not something on the case) as I mentioned about the Voda link leading to Malta's website and they mentioned that the phone left HTC without a lock and to the Czech Republic.
Anybody heard about gsm operators that are locking the phones themselves in HTC's case? If they know how to lock them, maybe someone knows how they do that and becomes easier to unlock?
Thanks for the help,
Sorin.
The IMEI could be blacklisted. You can check at this site: http://www.amta.org.au/pages/amta/Check.the.Status.of.your.Handset
Dunno how to see the IMEI on HTC phones though.. does anyone know?
Sent from my HTC Desire using XDA App
Tried that link and the message is that there is no lock (reported by somebody so that the carrier goes ahead and blocks the IMEI)
Hi again mate. I am impressed HTC answered so promptly thats great news they gave too. Just so we can all be clear on the type of lock you are experiencing can you tell us or better still photograph the screen and show / tell us the lock wording. Word for word mate including all punctuation if not posting photo.
Hey, here is the sequence:
The following happens when I turn on the phone with my Vodafone Romania sim card in it:
- I am requested for the PIN code, I enter that and then move on as the PIN is accepted
- Message saying "Unlocking SIM card...", takes about 1-2 seconds
- Message on the screen: "Network locked"
- I "drag" on the screen and get to enter the code
- Keyboard is up now and message changed into "SIM Network unlock PIN"
That's all, then the code that I got from gsmliberty.net, providing my IMEI and the fact that the phone is locked to Vodafone in Malta, is not working hence here I am on the forum
found this for you mate
http://androidforums.com/all-things-root-hero/119257-huge-problem-sim-network-unlock-pin.html
I know it mentions orange but perhaps its the same problem
Will definitely try to reflash with different baseband versions just to see what happens; however dont think that it will do the trick as I was reading in multiple places about the radio problem specific to Orange phones only. Of course you never know, problem is that I cant try it now as I am travelling and dont have the required info with me, but will do that over the weekend when I am back home.
Anyways, thanks a ton for the suggestions and everything, still open for more though
Hi, new info on the situation.
Came back home and flashed various older radio versions going down as much as 32.26.00.24U_4.04.00.03_2.
Same problem with the network being locked and the IMEI based code that I got not working either.
I also got in touch with Vodafone Malta asking if they can provide some help. The answer back was that they are willing to unlock the network for 50 EUR. However, even though I said yes to it, they dont want to tell me what is the procedure; they just mentioned that I should give my credit card details by e-mail and then they will tell me how to do it. I double checked about not going to some service location or sending the phone over, etc and they said that it is not the case, bu then again I am not ok to send over my cc details just like that and asked for an account where I could send the money; they replied that they will come back with that.
Well, this paragraph is just for your fun regarding the way Vodafone Malta is considering this option...cc details over e-mail...these guys are joking
Anyways, back to the issue at hand, any other suggestions about getting past the network lock if the operator changed the "normal" codes available on IMEI based providers across the web? How to override this?
Thanks!
Hi, back to square 1. After providing the IMEI to Vodafone Malta to get my phone unlocked, they replied back that the phone is not locked by them; so the whole thing with having the Vodafone Malta link on the desktop didnt mean a thing apparently.
I continued on the path laid out by HTC directly (they said that they shipped the phone to the Czech Rep.). I have a friend that has a Vodafone Czech sim card and tried it now, but it doesnt work either, so the phone is not locked under Vodafone Czech Rep either.
Any suggestion on how to proceed? Now I am very lost as I dont even know where the bloody phone is locked, as in under what network...
Thanks!
I have the same problem
i bought my phone at Montenegro T-Mobile,
asked the HTC for information about the phone giving them IMEI
the answer was exactly as yours
Tried to flash, downgrade, still have "SIM network unlock PIN"
Any suggestions
Haven't you tried asking the seller wich Vodafone is locked to?
Android on HTC Pro 2
Hi all,
i buy a htc touch pro 2 from USA var. T-Mobile.I install android on it and everything work's great until :
1.without sim on it, when I try to connect on my wireless network the phone close.When I start it "Gen.Y DualBOOT" not work.I reinstal "Gen.Y DualBOOT" same problem.Can tell me somebody what is the problem?
2.with card on it doesn't recognize the pin number and say's "sim card is locked".What can be?
Now I am in a romanian network (cosmote).
Thank you!
ok popepope, but why you insist on malta and on vodafone?????
your device mabe have a costum rom installed before you buy it. and from there you see vodafone link and malta, but like htc said that phone it's locked in czek, but it's not nedeed to be on vodafone. can be other network...

updating to nf9 lose sim unlock?

I was wondering if anyone knew if I update the baseband to nf9 will I lose sim unlock? I just want to make sure before I do since I use att on a tmobile note 3. Thanks
Updating to NF9 or any other firmwares, roms, mods, themes
or basebands have nothing to do with sim unlock.
Once your sim is unlocked the only way it will be locked again
would be if you or someone else locks it again.
It has nothing to do with any upgrades....
Good luck!
You will not sim lock.
Tip
I turn mine off when upgrading since you reboot alot. I turn it back on when I done. Same for screen lock.
error post
So, do I understand correctly that once I unlocked my phone with chainfire region lock which supposed to unlock SIM as well, my phone remains unlocked even after firmware update?
How about resetting NV? In other words does anybody know where SIM lock status is stored and what one should try to avoid to not disturb it?
The sim lock is tied to your sim card and you can change that by going settings, security, Sim card. The sim card lock protects your phone from being used unless the pin is entered.
Chain fire's region lock is totally different, it allows your phone to change carriers.
Sorry if I confused you. I was just stating when updating your phone you can turn off the security on your sim card and screen lock, so you don't have to enter them each time you reboot. Once your phone is stable reset the security on your sim card.
I think we're talking different SIM locks, I'm talking about this http://en.wikipedia.org/wiki/SIM_lock , you're talking about SIM card lock menu, but I believe OP mean SIM lock as enforced by service provider to not use another network, otherwise the title of this thread makes no sense.

How to unlock LG-VS870 4G LTE by Verizon

Hello XDA community,
I have Verizon's LG-VS870 4G LTE smartphone [http://www.lg.com/us/cell-phones/lg-VS870-lucid2]. Now I'm in Canada and would like to use this phone instead of buying a new one, therefore I was told to unlock it. Apparently it's legal to unlock your phone now: http://lifehacker.com/you-can-now-legally-unlock-your-cellphone-heres-what-i-1614787933
So I searched online for how to unlock my LG phone. Found many results that tell me the first half of the steps. Found a couple of threads here too about it, but no concrete solution. Some people said this phone isn't going to work on GSM after you unlock it, but I found this patch thread here that says otherwise: http://forum.xda-developers.com/showthread.php?t=2394689
I have the original Verizon SIM card with me too.
Won't ya kindly help a bloke out and tell him how to get the unlock code for his LG-VS870?
So, I tried to root it and was successful with Framaroot. Then Installed Clockwork. Then attempted to install the above mentioned patch using Clockworks recovery mode, but it didn't appear to fix the GSM lock. Whenever I insert my SIM card I get an icon that looks like a SIM card with a question mark inside a red circle at the top right. And when I try to dial a number, any number, I get some chineese lady saying something.
Any idea what does that mean?
I just unbricked/unrooted my phone back to 711A firmware and 4.1.2 Android as it was all the way from the beginning.
Here's the vocaroo recording of the chinese lady(WARNING! TURN DOWN YOUR VOLUME FIRST!): vocaroo.com/i/s0C5ObqOLK6Y

N7100, standard software, lost Network unlock after freeze, can't now unlock again.

Standard device, running 4.4.2, not rooted or changed other than by downloads provided by KIES, originally on 3 Ireland network, was unlocked and moved to Vodafone over 12 months ago with no issue, using unlock code provided by 3 after the end of contract period was reached.
Had a few strange issues recently but nothing I could be sure of, then one night this week, the phone locked and would not accept any key presses. Removed battery to force power down, then restarted, which has always worked in the past on the rare occasions when this has happened, but this time, when it restarted, it asked for a Sim Network Unlock PIN, which at the time I didn't recognise as being the unlock code supplied by 3.
I don't know if there are issues about the number of times this code can be entered, if there are, due to all sort of errors by Vodafone Support, that limit has probably been exceeded.
The other possibility is that a hardware issue has developed, but as it is only the phone network won't work, my instinct is telling me that this is a software and security issue that may have been triggered by too many failed unlock requests, though it still asks for an unlock code on power up.
So, what have I tried. After several frustrating calls with Vodafone and Samsung support failed to resolve the issue, I dismissed the PIN request and made sure I had some backups of things like Contacts, which worked, so the phone can communicate via USB, and it's also working with no issues via WiFi networking, as I can access things like Facebook via WiFi. My Google account is also working, it's downloaded and updated the applications that are installed on the phone,
In the absence of any real assistance from Vodafone or Samsung, in desperation, I've tried a factory reset, and also tried wiping the cache, but neither of these options are getting rid of the Unlock Sim request, which suggests to me that there is a flag or code somewhere deep in the system that's not allowing a full reset, and that may be related to too many failed Network PIN Entries.
Can I recover this phone, or am I better to just abandon it and get a replacement device, which in all honesty I don't need, the Note II is doing all I need at the moment, and a replacement is going to be an expense I'd rather not have to commit to right now.
I have all the details of the versions, IMEI etc, they are all accessible from within the phone using various *# codes, and they all are still correct and match what they should.
Talking to a local repair shop, if they ask for an unlock code, they are saying that the code they get will be the same as the one I already have received from 3, and as that seems to be not working, they are saying there's no point getting a code from them.
So, where do I go from here? Somehow, I think I need to find a way to wipe everything in the phone, and then reset the IMEI to the correct value, which should in theory allow the device to work again, and recognise the unlock code. That's a lot more than I've done on a phone, I'm computer literate, but not Android and phone experienced, so a lot of the buzz words are not familiar, or mean different things to what I've been used to on other systems.
If I am going to be completely wiping it all, is there any way I can change the service provider to get rid of the issues with the network unlock code, or is that asking for more aggravations?
Thanks in anticipation.
There is a free method that can be used to sim unlock the sgh-i317m which is the North American version of the Note 2. You had to flash back to a stock 4.1.1 ROM, and follow this guide: https://forum.xda-developers.com/showthread.php?t=2014982
The 4.1.1 ROM for the sgh-i317m Note 2 from sammobile.com does not include the 4.1.1 bootloader which is why the downgrade from stock 4.4.2 to 4.1.1 works.
