[Q] Strange behaviour of Lumia 928 (asks the SIM PIN code twice) - Windows Phone 8 Q&A, Help & Troubleshooting

There's something which goes beyond my understanding so I'm placing my question here if someone would know anything about it.
I purchased an unlocked Lumia 928 about 6 months ago and back then it was running on WP8.0. Been using it within Elisa (FInland) network and it's been good.
Because of Verizon's late updates I installed Developers Preview WP8.1 to it. After the installation the phone started to ask the SIM PIN code twice. After that it thinks for a while and connects me to the network.
OK, about a week ago my phone showed a message that Lumia Denim is now available. So by using Nokia/Lumia Recover tool I tried to downgrade my phone in order to get rid of DP WP8.1. After that Denim was installed. Its version number is 3051.50009.1446.0093.
When I switch my phone on, it'll still ask the SIM PIN code twice and thinks for a while. After a while it connects me to the network.
I tried (once again) to downgrade the phone but it'll only get me to the version 3051.50009.1446.0 which doesn't help me at all. So it won't go further in its downgrade process. And after that it'll still ask the SIM PIN code twice.
OK, last attempt: I made a hard reset. After setting my phone and switching it on for the first time it'll tell me that I don't have a SIM card installed but after that it'll connect me to the network.
Quite strange behaviour and I'd like to get rid of that "asks the SIM PIN code twice" procedure but I just don't know how. It seems the phone is "thinking" itself as a dual SIM phone Plus the MMS messages won't work at all.
So I'd really appreciate if someone would know a way out of this problem, whether it'd be a simple one or flashing the phone with a different SW version etc. Thanks a lot in advance!

Perhaps the second code is the code lock the Smartphone

No it's not.
When the phone asks for the SIM PIN code for the first time, it's real. I won't get any further if I don't enter the correct SIM PIN code there.
When the phone asks for the SIM PIN code for the second time, it's a fake. I can enter there a random four digit PIN code and the phone will accept it. Strange indeed.
I'd like to ask two additional questions and I'd very much appreciate if someone could answer them:
1) how to get rid of Lumia 928's MMS message issue? It's not capable of sending & receiving any MMS messages,
2) how to revert Lumia 928 back to its "from the box settings", i.e. WP8.0? Is there an unofficial way of flashing the phone etc.???
Thanks a lot in advance.

did you ask here http://forum.xda-developers.com/showthread.php?t=2515453
maybe you can use that to roll back to 8.0

having problems unlocking the sim on my phone.

I'm not sure if this is the right place to ask this question but it did say general for the htc kaiser.
I've recently acquired a htc kaiser from a friend. I contacted at&t for the unlock code but they gave me the wrong one. By the time I recieved the correct code I could no longer attemt to unlock the phone because there had already been 5 attempts. I have seen on some of the posts here that after 5 attempts the phone is permantly locked. Is there any way to get past this issue? Can i still use the kaiser sim unlocker without bricking the phone?

If you used your PIN 5 times you will need to enter your PUK code (You should ask AT&T for it, If you didn't get it when you received your sim)
I appologize I wasn't specific enough. My carrier is T-mobile and the phone is from at&t. I trying to unlock the phone so it will recognize my sim. There has been five attempts to unlock it and now it will let me input a code but I can't use the ok button to process the code. The message on the screen says "please wait until timeout is over." I did try using the puk code but it wouldn't let me confirm the code.
I already have the 8 digit unlock code from at&t.

[Q] Does "SIM network unlock PIN" necessarily mean the phone is just locked?

[Q] Does "SIM network unlock PIN" necessarily mean the phone is just locked?
Hi all, so here's the story - I bought a used Samsung Vibrant (at&t galaxy s 1), upgraded to 2.2 to get the unlock code, unlocked it. I then tested it with my GiffGaff (o2 UK simcard) and it worked fine. Then I proceeded to flash CM7.1 on it and just assumed that it remained unlocked and forwarded it onto my friend in Japan.
Now that he recieved it, he put his softbank sim in and he's getting a "SIM network unlock pin" prompt when the phone is turned on. Now, I'm a bit confused as to why that's happening because I had previously unlocked the phone.
My questions are A) could flashing to a new rom have un-done the unlock? I thought not...but I can't seem to remember if I ever read that or just think that B) does "SIM network unlock pin" indeed only point to the fact that the phone is locked? From the various threads here that I've seen that contain the same message, it appears so...but I just want to double check?
The main issue is that there's another message saying 9/10 attempts, so I'm afraid to just give him (show him how to obtain) the lock code again.... if he did try it, and for whatever reason it didn't work, would it be as good as bricked? (I can remember back in the days when I would unlock the old school non-smartphones that once you reached the X or Y tries for entering the lock pin, it would become unusable)
any thoughts would be greatly appreciated!
update: oh man, I just found out that I sent him the wrong captivate...problem solved....his is indeed locked/etc. sorry!

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

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?

[HELP] Sim Locked!!!!! PLEASE HELP!!!!

This morning I updated my note to 4.0.4
After updating it suddenly I wasn't able to make any calls or messages. I did some research and I have discovered that my phone had suddenly re-locked itself and is unable to allow my sim to work with it.
After doing more research I have rooted my phone and tried the Galaxy S unlock (which supposedly worked with the Note), and ended up with something like the attached picture. I see random icons but no specific code.
Here's a little background info that may be useful.
I bought this phone over in HK while I was there for vacation. The network lock occured when I first bought the phone but then the store that I bought it from found a way to fix it (without rooting the phone). Even when I upgraded to the OTA ICS there was no problem at all. I don't know why suddenly with this minor update it reset the network settings.
When I look into the mobile networks on my phone's settings a window pops up saying "Insert SIM card: Insert SIM card to access network services".
Which to me was kind of weird since I have inserted my sim into another phone and is able to make phone calls just fine.
Please help me! I have no way of contacting that store that I bought the phone from and I'm in need of getting my phone to work asap.
I am not lazy or anything, I have spent the last few hours trying to figure out how to solve this problem.
I have no experience in flashing a new rom and I really don't intend to do so unless i have no other choice.

You can - I believe - Downgrade to GB and run the unlock tool mentioned in that thread then upgrade again to your ICS..

[Q] Can't set APN, and other SIM problems

Hello,
I have problem with SIM card on my phone. I'm using Temasek's CM 10.1, Kowalski kernel, and V20I-EUR-XX baseband. When phone boots, I normally input my PIN, but it doesn't connect to network, I have to go to Mobile networks and Choose operator automatically, then it connects. I can call and send messages normally, but when the call hangs (me or the other side) it says SIM card error (something like that). Also I can't save APN. In APN settings there is nothing, and when I create APN manually, I input everything and press save, but it doesn't stay, APN's remain empty. I use micro-SIM with adapter, because my operator couldn't get me normal SIM at a time. I'm on Croatian provider VIP. Everything normally worked with micro-SIM from Tele-2 provider (although on CM 10, and CM 7, didn't test it on CM 10.1).
Is it related to my SIM card or SW (ROM or baseband)?

Not sure if you read my post, but I think we are having the same issue regarding the APN, etc.
Not been able to solve mine yet, perhaps together we can put out enough info that someone here can offer a solution? I haven't changed the baseband or kernel on their own, only went from stock 2.3.3, to CM10.1, then to CM7.2.
Are you able to remove the SIM PIN? If you remove the SIM PIN from security, are you able to save APN?
Does your phone access data with the native SIM card the phone was originally locked to?

It seems that PIN is already disabled in Settings-Security-SIM card lock settings :silly:
I called my old operator and they told me my phone was sold locked, and new operator told me they can't help because I didn't buy the phone from them. But then how it works now for calls and messages?
I don't have any other SIM with me so I can't test it with my phone. You say going back to CM7 didn't help? I guess I shouldn't try that then.
Maybe flashing stock ICS would? Any other suggestions?

I haven't tried stock ICS yet; maybe it would? I will try that tonight.
Mine shows the SIM PIN on, when I try to change it it asks for my old code, which I don't have of course, so I can't remove the security. Been hoping that someone else would have had experience or knowledge of what would cause the problem and have a solution or suggestion to try. The closest I came was on a different forum about a Sony Ericsson phone, but the rooting and flashing procedures are so much different I couldn't see a solution in it, though they suggested flashing the baseband iirc.
HMMMM, now that I read your reply, I can't say with 100% certainty that the phone was unlocked before I rooted and flashed CM10.1.....I had thought it was but perhaps it wasn't, and we are having a more similar issue than I thought. So the glitch, perhaps, is that it was not unlocked, the custom ROM somehow "half" unlocked it, and here we are stuck.
Okay, my only thought then is to take it back to stock everything, the most up to date I can find, then unlock it with code, and see if I can change the APN at that point. If so, I will root it, use My Back Up Root to save settings including APN (just in case so at least I can restore it that way if I can't do it manually, after)flash CM10.1 again or another fabulous custom ROM which is what I really wanted in the first place
I will try that tonight, and post you the results. Let me know if you have any (better) suggestions as well, I'm up to try almost anything at this point. Was hoping to upgrade to this for my daily phone as I'm limping along with a Acer Liquid MT that has seen better days
If anyone has a link to quickly point me towards the latest stock ROM etc. and wants to post here, I would be much obliged Might save this noob a few hours scratching his head to find what is most certainly in front of my nose already, but I digress...
Cheers
New baseband
I just flashed V30A baseband, and it didn't help. We can cross that from the list.
Well colour me confused...and happy?
I just today picked this project up again, about to attempt a different fix, again...*sigh.
Lo and behold, i insert my sim and power on the phone, and it asks me for network sim unlock.....odd because I'd used the phone with this sim before, through all my other testing, flashed different roms, etc. etc. In fact, I've used the phone on this very package, I know because there are sms messages on the phone from using it. Battery pull, remove sim and check, yup sure enough, old messages there. Hmmm...
Insert sim, reboot, asks for unlock code again. Well, what have I got to lose at this point right? As I said before, I THOUGHT I had unlocked the phone before starting this whole debacle, but wasn't 100% certain about it. Searched my email for the code since I always save them, couldn't find it. Well, in for a penny, in for a pound I suppose. Bought a new unlock code, waited for it to arrive. Input new unlock code, unlock successful!!
Reboot phone....waiting for service....(this seems like forever!!! In reality, less that 60 seconds.) Alas, I have service. And now, just to tempt fate, Apps->settings->wireless & networks->more->mobile networks->access point names..........:fingers-crossed:
I can hardly believe my eyes, there it be, Rogers Internet apn selected. It even auto-detected the damn thing!!
I can offer no further insight, I don't believe I physically did anything to arrive at this remedy. But there you go, for my part at least it's solved.
