Phone will not recognize sim/ imei "Unknown"/ baseband "Unknown"? *Updated* - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Phone will not recognize sim/ imei "Unknown"/ baseband "Unknown"? *Updated*
Updated title because problem has now changed.
current problem--
Phone is stock, randomly stopped getting signal factory reset phone using keypad, now phone will not recognize sim card, the imei is blank and the baseband is unknown. Tried reseating the sim, and powering on off.
initial problem--
After having a problem free note for some time now it randomly stopped working. I cannot make a call/ text or use data but the wifi works and the phone functions outside of those uses. When making a call I get various errors in the form of Mobile network not available/ Not registered on network and when i go into mobile networking settings> network operators it takes a while when searching and tells me to either try again later or gives me a message "error while searching for networks." When i take the sim out all together I get bars of service but when the sim is in it either gives me a circle with a line through it or a empty signal bar triangle.
I called straight talk customer support as i thought it was a problem with the service and they told me I had a bad sim card. I have since checked the sim in another phone and it works fine. I have tried multiple working sims in other phones and no luck in mine. The phone appears to be recognizing the sim as the apn settings are adjusting based on what sim i put in. I have tried to take out the battery, take out the sim, factory restore but nothing seems to work. I have also checked the imei number online to see if it was blocked or something and it said it was not. I took it to a local phone repair shop but after toying around with it for a hour they didn't know what was wrong, so here i am, hopefully someone can point me in the right direction. thanks.

May be the phone is network locked. is it asking for some kind of key or pin anytime or when restarting the phone?
where did this begin to happen?

No, its not asking for anything. I was like 10 miles from my house when it began happening and has continued since I got home.

have you tried changing modems?

After doing a factory reset using the keypad, *2767*3855#, it now says it doesn't recognize my pin and when i type *#06# IMEI comes up with nothing after it. Also, my baseband is now unknown. Is my imei corrupted or something?

Are you on a custom ROM...do you have imei backup... did you try to reseat the sim card

I know the sim isn't the problem as it works in another phone.

You may want to try flashing stock GB with PC Odin...then with stock GB recovery do a factory reset.
Don't do anymore factory resets if your on ICS and completely stock - you will kill your device...see the brick bug sticky

I'm assuming i have to root my phone in order to look at this folder? I'm looking into this now.

yes.

when restarting phone do you get the password prompt for the sim pincode, could be sim is not registered?
Anyways a stock phone should not do this. Its a case for customer service to fix efs. That appears to have instantaniously corrupted(!) first case I have ever seen of this.
Almost cannot believe it.
Without sim, is the imei there? I am suspecting your emei was gone before which you never noticed then. Is it even a new phone?
note rooting might void warrantee, so be careful

[Q] Samsung Galaxy S I9000 No Service!

Hope Someone can help.
I had a problem with my Samsung galaxy s i9000 and i was told to flash it using Odin, i downloaded the files from sam firmware and put android 2.3 onto it, when it had completed the phone will not get a service, everything else works fine and it reads the sim card and the contacts etc it just wont connect to network?
Can anyone help?
Thanks
Josh
Does it work wireless ?
Does it get phone network, or both data and phone services are unavailable ?
Do you have in wireless and network settings under mobile network the "use data packet" switched on ??
Did you try with a sim from another operator just to see if it's a matter of specific operator settings ?
I got italian language, maybe settings name are a bit different from the ones i mentioned, but that's the concept.

Check if your IMEI is correct, you find it under settings, about, status.
Your correct IMEI is on a sicker under the battery.

nope when i try and make a phone call or send a text it says "mobile network not available"
mmmm....
are you sure you downloaded the correct rom ? I mean there are different roms for different countries.
While you just reflashed, why dont you go back to original stock rom or to a stable one (one i remember is JPY_JPY_JPY) just to see if everything works fine ?
Anyway....which was the problem you had that required you to flash with odin ??
Yeah you prolly downloaded a rom fir another region if your imei is in tact and ya vant even make calls. If you can make calls and just cant use data then the rom doesnt have your apn settings and you will have to add them manually.

Have you bought it used with this problem?
If so there is a chance that the IMEI is reported stolen and blocked at the service provider.

[Q] S i9000 unable to connect to network

Hi, I'm hoping you can help. Total noob so please bear with me.
I got a Si9000, it says it is unlocked.
When putting in sim card I got data network not available error.
Installed S1_Odin_20100512.pit
In PDA option I put in code_i9000XXJVS_CL565837_REV03_USER_LOW_SHIP.tar
For phone option I put in modem_i9000XXJVS_REV_00_CL1059471.tar
For CSC option I put in GT-i9000-CSC-MULTI-OXAJVS.tar
After I was told to type in *2767*3855# to reset phone.
Phone has been updated to 2.3.5, but now getting not able to connect to network error. It says mobile network unavailable. Any Ideas?
Thanks

Yep, but wifi is the only thing thats working. No data or mobile network, no GPRS either
Which network are you with and what settings do you have in APN ?
Would recommend ...flashing Rom and Re-Rooting*
I am wondering if it's just something in the connection settings. When I went to Japan last year I had to fiddle with something in the settings before I could pick up signals. It was in mobile networks. I think you can select cdma or something like that.

Im with Go Conquer in Ireland, actually brought the phone to a shop to be unlocked, as it was Vodafone, but they said it already was unlocked. They have their settings up on their website so I have entered them.
I'm going to try putting it back to its original settings again, and rooting it again, do you think that might be it? Ill also try the cdma settings.
Thanks to you both
Follow my Guide below to flash Rom and then Root it
Why did you go to a shop to unlocked it ...theres apps on here free??
Did you manage to get it right again? I'm having the same issue as you do. I did a factory reset with cwm and now when I enter the sim card it doesnt connect to network or 3g. Wifi does work. I am on original rom 2.3.5 and I dont know what to do. I tried a other sim and that didnt work either. Please advice. Thank you.

Well, I'm not sure about the problem; if you are on a custom rom, it might be because of that, or incorrect flashing. Try using another ROM, and if problems persists try Stock ROM meant for your region. (it might be possible that you flashed a ROM for a different region and because of that you might have a problem..)
AND NEVER POST YOUR IMEI NUMBER ONLINE.

pop your sim card out for 15 min. then put it
back in your phone.
In the second pic it is clearly showing 1 bar of signal
So how can you say sim is not being detected

[Q] Invalid SIM card error/SIM network unlock PIN request on boot I9305

Okay, I posted this question in the I9300 Q&A section by accident (was a bit distraught, didn't read the section title properly), but for some reason a mod appears to have deleted the thread instead of moving it, so here it is again in the correct section.
So after using my I9305 for about 8-9 months now, I woke up this morning to find my phone nonoperational. The phone requests on boot a "SIM network unlock PIN". If this window is dismissed, the pulldown notifications drawer states "Invalid SIM card" with subtitle "Network locked SIM card inserted". Quick Googling reveals that these notifications and errors typically show that a phone is locked to a specific carrier. Now that's understandable, but this phone is unlocked, and I hadn't even taken the SIM card out until this error occurred. The SIM card works just fine in another phone.
I've tried rebooting the phone (first port of call), and using the code *#197328640# in the dialer to SIM unlock as per this post (but I didn't have "[4] NW LOCK NV Data INNITIALLIZ" as an option). I tried using "busybox chown 1001:1001 /efs/nv_data.bin" in terminal emulator as root, after seeing this post, but it came with an error of "chown: /efs/nv_data.bin: NO such file or directory". So... how bad do things look? And no... I don't have a backup of my efs. =[

Since then, I also tried *#06# in the dialer, and my IMEI is intact.

Not sure why doing anything with the battery would be in any way related with the SIM. I also forgot to mention that I had already tried cleaning the SIM card at the start with alcohol. In any case, the SIM card works fine in another phone, so it appears that there isn't problem with the SIM card. In any case, I managed to RMA the phone, now the long wait to get it back...

i have same problem with you 5 month ago with copy battery
Got my phone back from the shop today. Kept an eye on the shipping tracking when I sent it out, and they sent it back out half a day after they took delivery, so I'm guessing they used a SIM unlock code since it's definitely my phone that I got back. Didn't have to pay anything, so I'm happy. Still not sure why/how the phone decided to lock itself though...

Hey
Have you checked your IMEI number to make sure the phone is not blacklsited? Dial *#06# and then input that number into www.swappa.com/esn and or www.checkesnfree.com and hat'll tell you.
If you need help with anything and find out you're black listed (which it sounds like you are) or just have questions feel free to Message me.

My IMEI is not blocked...
Could be a damaged NV file. If you're clean imei and everything that would typically indicate damaged software to me. Have you tried flashing stock firmware to the phone? That might help repair the damage, afterwards perform a factory reset and wipe cache. A .qcn file written over a smart card usually fixes those connectivity issues. Just some ideas.

The first thing I'd do is ODIN to restore to 100% stock ( I know you've done it but I'd do it again.. make sure you put it in download mode with the 3 button combo, not any other way.) on the stock rom, do you have this issue?

Been on stock to fix this issue but nothing has worked.. There obviously no other way to odin the phone unless if its in download mode which i did.. I'm thinking hard ware issues
Did you do a nandroid by any chance? I had the same issue when I flashed a Rom, it corrupted my IMEI, nothing worked until I restored from my backup..
Were did you get this device??
