is my xda 2 locked?

here is what happened...
got my xda 2 a few weeks which was supposedly "unlocked" and installed a sim card from my local provider and i had mobile inernet for about a week and then a few days later it just stopped. i completely lost the signal and up in the connectivity section it just says "no service". i have tried a hard reset and that didnt help. i still dont know when the heck happned or what is wrong but now things have gotten even weirder. when i toggle between flight mode on and off it prompts me saying "sim card blocked. please enter PUK" does this mean my xda 2 is locked? is it possible for a device to be unlocked and then locked all over again for some reason?
i tried using the unlocking tool from this site but the one that runs off you desktop pc tells me the phone is already unlocked and the one you run off your pocket pc tells me everything is fixed but i still get prompted for the PUK?

your problem is that your SIM card is locked, not your device. This mostly happens when you try to enter the PIN code 3 times without success. The only way out is to enter the PUK code, so you can change the SIM password.
In Europe, this code is mostly given to you at signup time. Here, in the US, they make you call the telcom operator and dig it out of them, if you get a competent person on the other end of the phone line.
So, my bet is that you entered the wrong pin code for your phone -- and maybe you did this without even knowing you did it.

sigh...to tell you the truth i was hoping it was a locked xda 2...maybe that would of explained why im not getting a signal ...

You are not getting a signal because the puk is now required to access the sim/service provider. You should be able to get the puk by calling your provider or online through your providers internet site, you should then have a working phone again. To prove this to yourself just place another sim in the phone.

Problem with unlocking Rogers x10a

Hi all, I'm new here and before I tell you the problem, I appreciate all the info on these forums and the work that is put into everything. Thank you in advance.
So, I have a locked Rogers branded X10a, and I was unable to get the SIM unlock pin. So, I got the network unlock code, but whatever sim I put in, the screen always reads "no sim card" in the phone and then the activating screen loads and continues to load forever. Under settings (without a sim in the phone), there is the option for sim unlock pin, but that is the code that I am unable to get after numerous tries on different sites.
How can I get to the screen to enter the sim network unlock code if the phone in not recognizing any sim cards that I put in? Btw, I'm using AT&T. Any help would be greatly appreciated. Sorry for the length of this post and thank you.

I had similar issue my w580i. I had it after putting the unlocking code it stop recoganising SIM, havn't solution till now

Did you try using a different Rogers sim?

I don't have a rogers SIM, only AT&T. I bought the phone locked and just figured I would be able to get an unlock code like all the other phones I've had before, but no dice.

I just tried to put in my deactivated Rogers SIM card from long time ago, and I am also getting "No SIM Card" ... Not sure if your problem has anything to do with Rogers Wireless used to be "Rogers AT&T" before
If you have any friends has SIM card from different carriers, try to put those in and see if you experience "No SIM Card" issue.
Regards

Mabye it does.. I'll try and find someone with a Tmobile sim I guess.. thanks for the advice though..

Please keep me updated on this, I'm trying to unlock my X10, I got the code from cellunlock.net through the manufacturer and keeps telling me after I enter the code that it was unsuccessful.

I still can't unlock my phone either but I'm not sure about the SIM unlock code you're talking about. Are you talking about the IMEI? or the actual code that's used to unlock the phone? I've tried Mobileincanada.com but they couldn't unlock my phone and gave me a refund and I'm still waiting for this dealer on ebay. Good luck dude, keep us posted

Got an unlock code, www.cellunlock.net
Make sure to pick the Sony Ericsson Manufacturer code it's 34.99 but well worth it. It works now.

the manufacturer unlock code is the one I got, but I just don't get the option to put it in because the phone doesn't recognize the AT&T sims that I've put into it...

How old are the sim cards? If they are old, get new ones. Also, try re-installing the firmware through seus and then putting in your sim card. I never had that issue, I just had a hard time finding the code.

I had a real old one from cingular, but then I just went to AT&T and got a brand new one, but same issue. I'll try updating and see if that helps, but will the phone update without a valid sim inserted?

I had that same problem. Call AT&T or go to your AT&T account online and get the PUK number. Also, did you call AT&T and told them you have a new phone? They need your phone's new IMEI number.

I'm sorry, what is the PUK number for and also, why does AT&T need my IMEI number? I mean, the phone is still locked to rogers right now regardless, right?
Lots of noob questions, sorry.

Also, i already spoke to AT&T, Rogers and Sony Ericsson about the issue, but none of them are any help of course. The PUK did nothing for me either. I feel like I am running out of options here...

welcome to the club
http://forum.xda-developers.com/showthread.php?t=717414&highlight=phone+stuck
so far no solution

So, I tried repairing through PC Companion and then I also ran the update and go the newest firmware installed now, but still same problem. Phone does not recognize the AT&T when inserted and therefore, no option to enter the network unlock code. Any others have any luck/make any progress??

wow... i guess i'm in the club as well. I just got back from the Rogers store and they wouldn't let me replace the phone anymore. I've bought the manufacturer's code which is suppose to work 100% but it didn't...so desperate

Sorry to hear that...
You said the code you got didn't work? In what way? did you try to get a refund by providing video evidence?
On a side note, does anyone know how to access a keypad on the x10 that enables you to imput the left arrow, *, * left arrow method to input the code? I realize I need to have a valid rogers sim inserted in order for this to work, but I do not see how to input the arrow keys. Any suggestions? As I've said, I'm new to android and to a device with no physical keyboard, so maybe this is very simple...
thanks and good luck to others in the same spot as me right now..

LG Optimus Unlock -- Strange Security?

Hey guys, strange problem:
Got a Telus LG Optimus 7. Want to unlock it to Rogers. Got the unlock code, however when I use my Rogers SIM the Optimus asks for a 'PUK' number.
Long story short, I called Rogers, they gave me the PUK for my SIM. When I enter it I get 'SIM Error'. So I went to a Rogers store and got a new SIM card with a new PUK--same error. Tried someone else's Roger's SIM--still asks for PUK.
I called around, no one has any idea what's going on. Google can barely help. Telus tells me I have to pay $50 to get it off their network, but I can't trust the rep knew what the problem was and they won't just give me an unlock code I already have. A 'cell phone repair shop' tells me LG phones are impossible to unlock anyway (? really?). So my question is:
How do I unlock this phone? What kind of security is this (could the PUK refer to someother other than a SIM's PUK)? Anyone have experience unlocking a Telus Optimus? Can I flash this thing and see if it'll bypass the PUK part?
Any help would be deeply appreciated. Other wise I have to try and resell this phone.

So, I re-flashed the phone anyway, just to see if it works.
Now it's a little different. Now it asks for a PUK and once I enter that it tells me to create a PIN. When I do it says SIM ERROR! So while I can get a little farther it still errors out!
I've tried both the Telus flash and the Mexico flash.
So if it's not the firmware, what could be causing this?!

PIN & PUK security depends on SIM card functionality, in this case phone software is transparent and does not verify PIN. IMHO it looks like incompatibility between SIM card and WP7 phone or strange configured SIM card. Try on another non-WP7 phone, maybe if you set or disable PIN code card will function on WP7 phone.

Thanks for the tip elektryk. I think you're on to something.
I have tried the SIM in a non-WP7 phone. It works fine. I put it in both an iPhone and BB. Using the iPhone I created a PIN then tried the Optimus. It now asks for a SIM pin--which I input, then goes back to the PUK screen which still fails.
It seems to be a very strange incompatibility with the SIM, even though I've read reports of Telus Optimus being unlocked for Rogers SIMs.
Bad luck I suppose?

I have exactly the same problem. I put a SIM with PIN security enabled, and after I enter the correct PIN requests the PUK!! and if I disable the PIN secure, request inmediatly for the PUK. The Phone say: Your phone is Blocked. Contact the Service provider for an unlock code.--- the only problem is that I don't use the AT&T service, so I can't contact them!! HELP!!!!!!!!!!

Fabian, I could not find a way around the problem so I sold the phone. Luckily there was another e900h which was unlocked for sale. The guy followed the same steps I did but it never asked for a PUK. Weird how some phones do and others don't (especially considering both phones were from the same provider).
EDIT: Hey, try this, see if it works: Try without sim card for enter the unlock code. and type 2945#*900# for enter the unlock menu

Hey, start the phone without sim card, but no unlock code required, no where to type.

I've a E900h where none of the 5 unlock codes provided worked for some reason. Haven't ask for PUK yet but lost as to what to do right now.
Typing 2945#*900# just produces a failed msg - top left hand corner is a file icon with lock on the left.

In our country ones you buy a sim from network provider.
they give us a card with a PUK code for the sim we buy.
Try to contact your service provider.
Unlock codes is For unlocking SIm Only.
you can switch different SIM f u have unlock codes.
it is different with SIm Pin Code.
You can get Ur PUK Code to your service Provider.
what country were u from??
PRESS THANKS IF I HELP!!

[Q] Sim Unlock on CM9??

Is there a way to unlock the SIM for all companies on CM9? I tried the "classic" sim unlock for cm7, but it didn't work.
Thanks in advance.

Hey,
I have the same problem on an MB526 Can`t Downgrade Baseband or other Calculation has not working.
An other way to Unlock the device?

I would like to know this too. Just got a new sim card and no unlock options pop up after boot ...
how do I do it?
using cm9 on defy
----
so, I went and flashed the latest sbf back to normal froyo. I then realised the sim card wasn't inserted properly as froyo at least told me that 'no sim was present' rather than just saying there was no network. DOH!
So maybe it would have been possible in CM9 in the settings > secuity > sim unlock

Royal pain
If there is a way, to unlock a Captivate with CyanogenMod9, I would be most appreciative to hear it!
I have CyanogenMod9 , a Terminal Emulator, ROM swapper, and other brilliant stuff that I have no idea about but it came with the used phone I got from family.. who got it from someone else.
What I have tried:
1. Code Companies
2. Watching Video of 'Wei' from XDA over Youtube
3. Downloaded and ran 'SGS Unlocker' from Google's 'Play Store'
4. Read up on methods until it became info overload
The complications:
1. Code Companies- Want all the normal info that you'd submit to AT&T forms anyway but the Code Companies charge for a service anyways. They want to know the IMEI easy; the make&model- easier still; and the original service carrier - Straight Talk is AT&T, but then they had sueing issues and fighting and dropped support and junk that makes your head spin... the kind of info I can't even imagine where to start after it's been a hand-down three times. Then it takes 24hrs to get a code; a physical store that does this is even worse- they require more money and three days. Not to mention that you'd be the holder of the AT&T account to do it the simpler-/+Easier way through AT&T 'unlockdevice' .. and I don't recognize the SIM card except that it may be straight talk based off one result from a Google search using 'SIM 89014' .
2. Wie's video was informative, but when I typed the *#7465625# into the phone, it resulted in and error 'no network connection'(I can't begin to figure what that means); So no telling what locks are on the phone, the '*#746..' doesn't work for me.
3. Downloaded and ran SGS Locker from Google's- Play Store, but it results with 'no codes found' (*sarcastic* Peachy).
4. Read XDA forums.. at least five threads with multiple results each, but this is the only one I've found relevant to my issues with the CyanogenMod9.
So I'm burnt out and sick of learning about the Samsung Galaxy S1 aka Captivate aka i897 aka Vivid aka SGH-I897 aka WHATEVER! I just freaking want to use the phone on T-mobile services , unlocked or locked... I've lost care about unlocking to no carrier.
I have a Terminal Emulator though. Is there a step by step input that I can use to find the unlocking code I need?
Thanks.

SIM unlocked Galaxy S4 got locked again?!

So, I am very ignorant regarding cellphones, so I hope someone around here can help me out. I have a rooted Samsung S4 GT-I9500 that I bought in Guatemala from Claro company. I moved to Africa to work, so for me to be able to use my phone I bought an unlock code that worked just perfectly. My phone got sim unlocked and I was able to use it for several months until recently. One night my phone ran out of battery, so I plugged it to the charger and charged it all night [turned off]. Next morning when I turned the phone on, the phone was sim locked again and my sim card was not recognizable at all. the following message appears
"PIN to unlock SIM service provider"...when I click dismiss and scroll down the upper tab it says "Invalid SIM card...Network locked SIM card inserted".....
I tried reentering the unlocking code that I previously bought but with no success. I tried factory resetting and reentering the code, also no success. I also inserted my old Claro Guatemalan Sim Card and it is also not recognized by the phone. Does anyone have any clue or suggestions about what it could be and what I can do about it? Please make the explanations "for dummies" since as I said before, I am not that good with cellphone stuff. Thanks for your help.

Hello dollagaray,
I´m having the exact same issue. Did you find any way of solving it? I have flashed several firmwares and modems but nothing would unlock the phone again.
Thanks in advance!

I had this issue and ended up replacing the SIM card tray.
