Phone lost network

Hi all,
Today I find out that my phone is not connected to Rogers network. I have US phone unlocked and unbranded. I had for 4 months now and never had this problem. Right now, when I go to Wireless setting and try to find operator it keeps looping to find one, any help appreciated.

I had to RMA my phone when this happened
I'm sorry to hear that you lost signal to Rogers. My Captivate had the same problem over the weekend (not connecting to AT&T).
My local AT&T store couldn't find anything wrong with it but recommended it was a hardware problem and can be exchanged for a working phone. Even trying a new SIM card didn't help. Luckily I had flashed to stock and had complete Titanium Backups of my apps & data.
Typing *#06# in the phone dialer brought up my IMEI number. The IMEI displayed should have been the same as what is shown underneath the phone's battery but it was not. It started with 004 instead of 351.
At this point I'm not sure the malfunction had to do with a hardware issue or my ROM flashing hobby. All I know for sure is that I made sure to backup my EFS folder before flashing another ROM.

Generic IMEI number starts with 004
It's hard to stop a TRANE but harder to BRICK your GalaxyS. It's not a hardware problem U have software is your problem and it's easy 2 fix. Just flash back to stock JH7, after that do an ODIN3 Master-Clear. When ur done all will be GOOD ur IMEI will b correct, network will be back

I9000 imei problems

Hi everyone,
at a bit of a loss here . Bought a galaxy s i9000 which someone had had issues when trying to upgrade firmware- managed to recover it , but it has serial number issues ( 004990 etc ) strange thing is phone shows as unlocked but only works on vodafone and virgin which it does fine . When another sim card is used it shows network name but out of service - could it be the imei is being blocked or any other ideas - I am on T mobile so as it stands allthough it works it is not much use to me ,
thanks in advance .

Its possible, since you are using a fake IMEI and different networks have different policies, , you could try fixing your EFS, to get back your IMEI, solution on EFS, Click MY Android Collection Link below

thanks for the reply - I can see txt in folder showing correct imei but it displays "fake" one - think this maybe getting a bit heavy for me - can this be repaired at all
cheers

Flash gingerbread through ODIN
Hey I had an issue like that when my friend failed at flashing his phone and doing an odin flash to gingerbread solved it for me with re-partition selected

Phone has gone back under warranty so hopefully all is cool - if not I will try the repartition.
cheers

[Q] HELP SIM CARD Not recognized after flashing rom

Dear XDA I9070 experts I really need some help here.
First I want to apologize if I have some errors, my english is not very good, so sorry about that, I will try to do my best to explain and give the best background information if anyone can help me.
My actual phone is an Motorola Atrix 2, and I have flashed roms several times following the procedures explained on the threads here in this awesome site XDA step by step. So being able to flash roms with no problem at all I tried to do the same on my wifes old Samsung I9070.
I followed a thread that explained how to flash a ROM from GB to Kit Kat for the I9070 step by step here on XDA. The thread is this one:
http://forum.xda-developers.com/showthread.php?t=2198341
It all went fine but being that the phone was not being used by anybody I forgot to insert a SIM CARD before the flashing procedure. I really don't know if that makes a difference, but when the mobile booted the first time after the ROM flashing I inserted my SIM card and to my surprise I didnt recognized it... booted the phone again several times and nothing, but the SIM card is being detected right away on my Motorola.
So I tried to do some research about that and some people suggested to go back to stock firmware, and others told that it was a problem with the EFS folder.
So I tried going back to stock JB with ODIN, but this time with the SIM CARD inserted, and nothing, the same problem. So I tried inspecting the EFS folder and I think that is the problem but I need some advice on this.
The EFS FOLDER has this content:
A bunch of files named CRYPTPROP...
DECRYPT_KEY
ESSIV
GUARDFIL
NV.LOG
NV_DATA.BIN.MD5
And some folders inside... Thats all. I didnt made any backups of the phone or the EFS folder
So I tried using the code *#06# and it gives a valid IMEI 3544******* etc
I really don't know how the phone still shows a valid IMEI with the file NV_DATA.BIN missing, so I checked the phone information and found this:
Inside SETTINGS:
MODEL NUMBER: GT-I9070
ANDROID VERSION: 4.1.2
BASEBAND VERSION: I9070XXLQL
KERNEL VERSION: 3.0.31 - 1485715
BUILD NUMBER: JZO54K.I9070XXLQL
Inside SETTINGS - STATUS:
NETWORK: UNKNOWN
SERVICE STATE: OUT OF SERVICE
MOBILE NETWORK STATE: DISCONNECTED
MY PHONE NUMBER: UNKNOWN
IMEI: 3544******
Maybe the EFS folder is not all bad, I really dont know, please I need some advice here. My motorola screen is dying and I need to recover this one as it is a good phone. Thanks in advance for your help.

Your baseband is not missing, but anyway you can try this: http://forum.xda-developers.com/showthread.php?t=2677807
P.S. And you did factory reset after going from GB to JB?

Thank you very much for your help shut_down....
I followed all the steps and still No SIM... Insert SIM card message :crying::crying::crying:
And to answer your question... yes I did factory reset several times... wiped cache, everything... several times after flashing :crying:
Any other suggestions?, I really don't know what else to do... thanks in advance for your help and time.

What JB rom did you flash? Link? Perhaps any Baseband problem ... and where are you from?

Thank you Flo0008 for you help... I used a firmware from Sammobile... this one exactly I9070XXLQL_I9070ITVLQ5_ITV as it was one of the more recent ones.
By the way I'm from Venezuela, but I bought the phone new and unlocked from amazon, the phone is in mint condition and my wife used it for more than a year without any problems, also we use the same carrier... it was not used anymore since December 2013 and recently I charged it for a full battery and did the firmware flashing and since then I'm facing the No SIM card, Insert SIM card message.
Could it be the firmware I selected I9070XXLQL_I9070ITVLQ5_ITV the problem?... It's from Italy... maybe you can recommend using another one.
Thanks in advance!

I had similar situation once when I tried different SIM card. My solution was to put SIM a bit twisted into its bed.
[\] instead of [|].
It took few tries but finally it got detected and working.
Sent from my SGS Adv. using xda-developers app.

most likely your phone was *not* SIM unlocked before you flashed it: I did the same thing to mine and read many similar stories here and there.
I never found a solution and bricked my phone while trying to fix it. I went up to copiing a full ROM dump from another working 9070P: the copy succeded and phone worked (IMEI cloned etc...) but still no SIM card recognized (it was a spare free one so not a problem
If I manage to achieve my unbrick procedure (http://forum.xda-developers.com/showthread.php?t=2701363), we might be able to fix that by reseting the full ROM to a valid state.

Facing the No Sim issues
i am facing the same problem, and it was all of a sudden."No SIM"
I sent the phone to service center, but they failed to repair.
i have tried everything, hard reset, downgrade to GB, upgrading again to JB (via ODIN), custom ROMs, but no luck.
what i figured out is my phone works on some older SIM cards, which have square shaped Chip (like the one in BSNL sim).
any suggestions????

[Q] My IMEI was deleted. Factory data reset doesn't help.

Hi All,
Something really strange just happen with my GT-I9295.
So I got the 4.2.2 version from the box. I recived an automatic upgrade which I have accepted and installed. But strangly after installation the version still 4.2.2. One week later the IMEI number just disapeard durring the night and cannot recover it anymore.
Network
Unknown
IMEI
Unknown
I didn't installed any custom ROMs, nothing.
I found that the IMEI number should be in EFS folder after factory data reset, but this file is missing there.
I have my IMEI under the back-cover, but how I can re-enter it in my phone ?
I heard the param.bin for gti9295 could help ? Could somone drop it here ?
I bought the phone 2 weeks ago
When I tried to repair it I have root it. How I can check my KNOX counter to see if I can send it back to Samsung ?
Thanks in advance and sorry for my english!

Unknown IMEI and locked network after trying to recover

Hi everyone,
Hope you can help me solve this, cuz I'm way out of my knowledge..
My phone broke the lcd and was out of action for a few months.. After I finally got a replacement screen, the phone wasn't working and said IMEI unknown, I've tried to flash a few roms via recovery but nothing. So I just went crazy and flashed it via kies. It worked, the imei appeared but the phone was locked again..
Back to the shelf a few weeks until I could afford to pay for unlock.. When I picked it up, it was unknown IMEI again and the guy at the shop basically told me he couldn't help.
Was he right? I refuse to believe I can't recover the phone.. Can you please help?
Thanks!

Anyone?

Are you sure is that phone imei is not blocked, because provider may block if it is stolen reported.
I had the same problem after changing display IMEI unknown
But somehow it was saved from 'unknown IMEI' I don't know how.
restored efs from previous backup (twrp & philz recovery)
- no imei
I flashed stock
- no IMEI
asop
- no imei
tried different modems
again stock
- suddenly its worked
(some users reported flashing different modems worked for them)

Yes I'm sure imei is not blocked by network. Have a friend that bought a phone which he discovered the hard way it was stolen, anyway, blocked imei by network behavior is completely different.
This is what happened to me first time only valid imei after kies rom update.

If you see imei again, Make a backup using pc, there is a guide in development section. So, you can easily restore again.
