Okay i own a desire 816, bought it a couple of days back. I changed the lock screen security from pattern to password. After setting the password when i enter the password it says wrong password and doesn't unlock. The WiFi is turned off and so are other wireless networks, Also i cant go to hboot menu cause fastboot is ticked. ADb wont work cause USB debugging isn't enabled either. And the "forgot your password" thing is also not appearing. Help me please. I have the dual sim version.:crying::crying::crying::crying::crying::crying::crying::crying::crying:
Please help
I'm not sure if there is an "emergency" bypass for the lock screen. Worse comes to worse you'll have to do a factory reset

How does one change the settings to allow a PIN authentication before the usage of phone everytime? I tried to activate the PIN under the 'Phone Settings' option but it seems that it already has an old PIN which i am not aware of and until one knows that, it wont let a new PIN be set up. As a cautionary note, there are only 3 chances to set the PIN, i dont know what happens if you fail at all three attempts...may be it'll lock the phone/ SIM? Does anybody know more on this....care to share!
Thanks
You wanto go the the 'Lock' settings and setup that your phone locks itself after so many minutes and what password you want to unlock it.
Unlike traditional GSM phones, Windows Mobile does not use the GSM Pin mechanism due to the fact that Windows Mobile did not originate as a phone device and thus used its own locking mechanism.
I imagine you could lock the SIM card by entering the wrong PIN or if you flagged in the SIM card itself that a PIN needed to be entered to active the SIM (as thats how the GSM technology works in that even if you transfer the SIM it will still ask you to unlock that SIM card in another device). However, due to the nature of how Windows Mobile works your device would still be accesible, just not the network related tasks of calls and data. So I would recommend just using the Lock settings.
All SIM cards (unlike Windows Mobile) have a default PIN code as it can't be blank. Ask T-Mobile what it is (or it may be in the manual), but it generally is either 0000, 1111, or 1234. But don't try too many times as that will lock the SIM card and you will need a PUK code to unlock it.
Hey thanks for your reply, its pretty comprehensive and it worked for me. You were right, the options of the PIN under phone settings are :
1. For authentication at the time that the phone is starting up after a shut down or restart.
2. For SIM authentication.
But i was looking for locking my fone when i am not using it and as u said that feature is under the LOCK settings.
Thanks again for your input.
Hi everyone!
Just received LG Nitro HD which was bought on ebay.com (USA). As I live in Europe I can't use AT&T so I had to buy the unlock code and I did so. When I received the codes (NCK, NSCK, SPCK, CPCK, SIMCK) the Life's SIM was already in and I was doing some setup (can't remember exactly what, but not in wireless networks). So I decided do not reboot the phone and use 2945#*930#.
When I entered the code I get in the unlock menu. I pressed Network lock and the new menu popupd. I've entered the NCK and phone says that the Unlock was successful. Than I tried to press other menu items such as SIM unlock, Corporate unlock,... but without any effect.
After that I decided to continue my "exercises" and went to main screen and I didn't saw the network connection.
Than I've tried manual search, automatic search, other SIMs (from other carriers) - the only network which the phone can connect is life but connection loses in a few seconds. BT and WiFi works perfect.
I've tried to flash 10i.kdz, 10c.kdz, 10f.kdz, 18f.exe, 20c.kdz - only 10s and 18f.exe can start, others stuck on bootscreen.
Please help me how to connect the phone to other networks and make signal straight!!!
have you entered your apn settings for your carrier?

No, but they are received automatically somehow (maybe they are flashed at SIM?) for all networks I've tried. And they are correct - I've checked it on operator's sites.
Insert any sim and do a manual search. How many networks you see?
Also verify wether it is on 3G only or anything other than automatic cause in some devices it sticks even after full flashing. If that fails, best case scenario, antenna problem.

With any SIM or without any SIM, with manual or automatic search, with "2G only" set or not set it could see only the network named "life"
So I decided (the day before yesterday) to disassemble it and see what is happened inside. And I saw that some wire was not plugged but only putted on the board. I plugged it and powered on the phone - and IT HAPPENED!!! All the networks where found!!! So I've assembled it back and the problem was resolved. Sorry, I was so happy and didn't wrote about it.
The problem is decided, case is closed. Thanks for everyone for help.
rofl, yeah plugging your antenae in is kind of important
Phone is an S3 for T mobile running 4.1.1
I've been in phone unlocking hell for 4 days.
Closely followed the "free" unlocking in debug mode method-trouble was phone will auto lock back after a couple hours or calls.
Tried turning the flag on and off, factory reset, all kinds of stuff and still no luck.
I broke down and bought an unlock code but can't get my phone to prompt for it.
I can't seem to undo the service mode change or find a way to enter the unlock code.
The phoen will not prompt me for an unlock code no matter which way I try to reset it.
Have you tried to odin to latest jb stock ?

Are you inserting a non T-Mobile sim card into your phone? ( I am assuming that your cell phone is the t-999) That is the only way your phone will ask for the unlock code.

yes, inserting non t mobile sim- it doens't prompt for unlock code
If I root and flash a different rom does does it bypass all hte lock/unlock BS or am I still going to have to figure out how to get that code entered
Also tried reinstalling drivers from kias- just rooted phone-it wouldn't be much trouble to install a different rom if that is the fix.
also I bought an unlock code but don't see a place to enter it in
Not 100% sure but I was under the impression the simlock feature was null on sgs3. I have no issues with mine using straight talk wireless full unlimited ($45 per mth). Aside from that, if you can give me some info on what you have done I might be able to help more. There are a few settings that need to be changed as well as phone based service menu changes.

ok
Inserted foreign (non t mobile sim)
Got a prompt for an unlock code, which I didn't have.
Used Google, found a way that looked promising by going in the service menu.
*#197328640#
Main Menu
[1] UMTS
[1] Debug Screen
[8] Phone Control
[6] Network Lock
Options [3]Perso SHA256 OFF
(after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in
[6] Network Lock then choose
[4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone
Ok did that then phone worked. Kinda. It works for about an hour or a couple of phone calls, then the phone says "searching" and I don't have any network connection.
Also tryied turning the SHA256 back on, back off, intializing, every combination you can imagine, same result, phone doesn't work.
Bought an unlock code but can't get the pop up to come on to ask for it so I guess it is worthless.
Tried reinstalling firmwire via Kias. Same thing.
Rooted phone thinking that might be the answer. Worked for a day then same thing.
Spent countless hours on google and these forums trying to figure out a way to fix it.
is flashing a rom a solution?

What APN's do you have?
never mind got booted off again...
phone says "searching"
internet was off
this thing is crazy
It will work just fine then all of the sudden nothing-move sim over to my flip phone and it works fine.
It's like the phone is shutting itself down.
Have you changed your service address? Sounds like your sgs3 isn't finding the correct path to your new network. ....
In your Phone: Go to settings<more settings<mobile networks- then touch the option network operators to scan the available networks in your area, wait for some moment, let your phone scan, a list of available networks in your area will appear then, select the network name of your service provider to register it and you are done. You can restart fore more efficient use then.
This is from another site, I have cm nightly so my options are a lil different now. That being said after manually selecting my network with stock rom, setting my APN/WAP had no issues. With the cm nightly I didn't have to change anything. I'm thinking one of the os updates might have made it hard to access or change this option. Will try to grab a dev friend to look into this for ya.

My service provider is Cellular One.
I have three options
Select automaticly
Default setup
Search now
Selected search now
It has two
T-Mobile
311040
I selected 311040 and nothing....still got the "searching".
then selected "T-Mobile" and my phone connected to "cellular one".
please please please let this thing be fixed!
Ok we are getting somewhere.
Last night after I "registered" to T-mobile the phone did fine.
Today I stopped in at Cell one on the way home and told them I thought it was fixed and what I did.
She said that isn't good because I will get booted off when my bill comes because 50% of my useage has to be on cell one network.
So she scanned there at their store and set it to cell one.
I get back home and I'm booted off again. I tried to put it back on T mobile and I get an error now that says my Sim does not allow to register on this network.
Is there anyway to get ALL of T-Mobiles stuff off of this phone?
Would flashing a ROM do that?
I want to make sure I provide as much info as possible and I appreciate any help which is offered. I'm currently in Latvia with my T-mobile Note 2. I received the sim unlock code prior to leaving the U.S. and applied it upon purchasing a Latvian sim and entering the sim card pin. The phone grants me access but immediately begins locking up and issuing an error window stating "unfortunately, Com.android.phone has stopped."
When I enter the mobile settings (which is difficult to do in between crashes) the latvian network is recognized shortly but I cannot change any settings and the network indicator in the pulldown always says searching. I've tried to change the network mode before hand from Automatic LTE/3G/2G to 3G/2G or whatever, but that doesn't help.
If I place the device into Airplane mode, it stops crashing and I can use wifi (which I'm doing now)
Here are my device details:

Short of trying a factory reset, have you tried clearing data from the telephony related APKs?
Perhaps the SIM is a dud?
"SIM Suddenly *Perso* Locked?!" <-- (Thread Tittle Typo)
Hello XDA. Mayhaps you can help me solve a problem that came out of literally nowhere.
I'm using an AT&T Galaxy Note II on Metro PCS with Cyanogenmod 13, and I have been using this setup for a few months now with almost no issues. Now don't get me wrong, I've had some hiccups here and there. Random reboots, camera issues, once I even lost ALL of my personal data for seemingly no reason at all.
Right this very moment, however, my phone just randomly rebooted, which I'm used to, but upon unlocking my phone after startup all I get is "Unlock Sim Network Pin" - "Sim Perso Locked Emergency Calls Only"
I have NO idea what is going on or why this happened in the first place. I don't have the slightest clue on how to fix this at this hour other than paying for an unlock code from a third party, but there's no way I'm doing that! Please help.
TL;DR
My phone rebooted and now the SIM is locked for no reason. Pls hlp
How did you sim unlock the phone in order to use Metro PCS? You mean the sim is locked in that the sim card is asking for a pin?

When I bought the phone off of a friend they asked at&t to unlock it and they obliged.
Yes, that's exactly what I mean. Every time I restart the phone it asks for a pin to unlock SIM.
I'll update with screenshots.
Once the phone is unlocked via code, it should be permanently network unlocked. Do you still have the unlock code?
If the sim is asking for a pin, sounds like a setting in the security may have been changed to prompt for a pin. Did you try entering 1234 or 0000?
Same thing just happened to me, what was your solution? Phone worked fine yesterday, powered down from battery use, when I plugged it back /charged it, it was doing the perso lock thing.
