[Completed] [Q] Internet problem

Have updated my spica from 2.1 to cyanogenmod-6.1.1-spica-alpha8.3 build number K/Criminal.r6
Everything is perfect and I like it, but It cannot connect to internet.
Here is the phone status
Signal strength is changing but have managed to see this -111 dBm 4 asu
Mobile network-both edge and UMTS
Service state-in service
Mobile network state-disconnected
IMEI-000000000000000

Bluetooth address- unavailable
I tried to re boot, I also tried to re-install the rom but I have the same problem...I read somewhere about updating prl, but I could not do it because those #### thing are not for my network providers (my country is zambia,africa).
When I flash it back to 2.1 mobile internet service is perfect.
What is the problem here?
Your help will be really appreciated.
Thank you
Hi!
That's very bad news. Are you sure you updated with firmware for your exact device? Your imei has been erased, making the phone useless as a phone. No data, no calls and no texts.
If you have a backup from before the update, restore it. Hopefully the efs folder was backed up. Without a backup, you may need to send your device for service to have the imei restored.
See this similar thread for more of an explanation.

I hope you can get it resolved. Good luck!
Ah, you do have a backup. Restore it and don't flash that rom again. Its broken your imei.
Please be more careful what you flash and be sure it is for your device. Sounds like what you flashed was for another device.....or something just went very wrong.

[Completed] [Q] Xiaomi Mi2s - No cell signal after IMEI restore.

Hi.
I have a Xiaomi Mi2S that doesn't connect to any cell networks.
I'm using CyanogenMod 11 nightlies, and after an update the phone lost its IMEI number. I had taken a backup of the NVRAM using EFS Professional, but when I looked for it the files where 0 bytes in length (probably a hard disk problem on my computer)
After trying a lot of stuff (installing stock MIUI, putting the phone in diag mode and installing a bunch of drivers), I managed to restore the IMEI number, but the phone still can't connect to the network.
I have tried a SIM from another company and it doesn't work. And my SIM works correctly in other phones, so I think that is not a SIM problem.
I don't know what to do... I tried flashing different ROMS, tried flashing a new baseband radio, but I can't get it to work! Is the phone lost???
Can anyone help me? I would appreciate it very much!!!!

Same Problem here
Hi I'm using the Galaxy J700H phone its like 2mos old, and have the exact same problem, so please can someone help? My problem is, I think also is my IMEI number? When i dialed *#06# on my phone my IMEI is 350000000006 and FTW that's not even my IMEI anymore, I have the original IMEI number here backed up but i tried everything, step by step. But sadly nothing worked out. I used this sim card in all of my phones and lastly when i wiped out my phone and flashed custom rom in it, then this happened, then i decided to flash the stock rom that has been downloaded from the sammbobile.com website, after that nothing happened. My phone always displays EMERGENCY CALLS ONLY.. pls help

[Completed] Nexus 6 No LTE with correct IMEI! "0" Imei and LTE!

Ok, Ladies and Gentleman I need some deep thought processing here for some help with a Motorola Nexus 6. In brief here is what the problem is, a while back when flashing Pure Nexus rom, I experienced a loss of my IMEI. I can restore my IMEI but if and when I do, I lose any 4g and LTE connectivity. The phone functions in 3g with data and phone etc... just slow as molasses but if I restore my IMEI to the one that doesn't show up my IMEI correctly I get back LTE/4g and all works fine also. I've tried going all the way back to the original firmware which was saved to computer and restoring it. Same thing, I have IMEI but no LTE/4g. restore bad efs and get LTE/4g back. I've tried going through all the factory firmware's and flashing by ADB and or TWRP and nothing firmware wise will allow me to restore the IMEI and have LTE/4g signal. If I restore the bad efs and get OOOOOOOO for IMEI when using the *#06# on any firmware version, I regain LTE/4g functioning! I am using Pure Nexus 7.1 now and can still see the 00000000 as a IMEI, if I restore my efs and get IMEI back showing correctly, no LTE/4g signal! My phone can only function as it should as long as the IMEI doesn't show correctly! I have tried just flashing base bands and other segments of any rom and still the problem persist! I have even tried restoring an EFS from another nexus 6 and still no help. It's not the sims because I've tried AT&T sims and Verizon sims from other phones and it does the same thing! I've tried flashing with a sims in the phone and without. Any ideas??? It's like somehow a correlating segment of a file is not being recognized when the correct IMEI is present, like some thing some where in the efs, IMEI, and radio are not taking to each other so to speak, unless it shows the zero's! Brain waves come on and help me out here!

[Completed] Have signal but not registered on network

I have Samsung Galaxy S3 GT-I9300. When the google drive app was downloading from google play, my phone went off due to poor battery. Later when I tried to turn it ON, it has been getting stuck in the boot. So I decided to reinstall my custom ROM. Being busy with my baby, toddler, household chores and job, I gave it to my brother to flash the ROM. After a while, I noticed that my sim was bricked.
It says "Emergency Calls Only", has fake IMEI but working signal.
We did not backup the efs. I tried searching all the methods like modem installation, CSC, baseband verions, IMEI re-write, Kies Upgrade and Initialization, other people's efs restore, etc. But the problem is unchanged. Some of the followed method might have failed for not having proper knowledge like IMEI re-write tool works on specified chipset, etc.
What we noticed is that using different baseband version toggles from having network signal or no signal.
Kies shows more than four firmware versions and no other details like CSC, etc.
How do I clean up all these especially to have SIM working on my phone?
I appreciate you assistance to be brief and clear to understand steps than sending links. Because my time is stress-fully short.
Hi !
There is some confusing info in your post
What do you mean with it has fake IMEI " ? Have you changed it ?
You say that you have a working SIM on certain basebands , is this happening on a custom rom or stock ?
Have you tried to flash a stock firmware as I see that you tried to flash "your custom rom " ?
Cheers !
First of all, thank you for your response and interest to assist.
My mobile's IMEI is shown as 004999010640000 which is not original. Can you help me to change it to correct IMEI suitable for my Samsung S3 GT-i9300 chipset, if that helps in enabling sim to connect to a network? I think changing method only masks the IMEI?
I have tried flashing stock firmware and also Kies Upgrade and Initialization.
I have also changed baseband version installation on stock ROM too. I don't know which baseband is correct to keep.. for my country India or in the country where my mobile is manufactured, incase that's locking sim accessibility? Some baseband bought signal and detected the network operator name, but the message still says "Emergency Calls Only" and is unable to connect to a network.
I presume this problem arose when installing custom ROM from TWRP recovery and it messed up with efs partition?
I had successfully flashed custom ROM many times before without this problem. I think there's some next step to follow to bring back the working sim like I heard of installing modem. I did just try installing modem but same problem as my baseband is already bringing signal.
I had tested my phone from sim unlock app and found out that CSC is locked and it limited specified MCC and MNC numbers. Is this hindering connection to Indian mobile network? Or corrupt efs? Or missed to manually install something?
Bump.
