Which ROM is your phone on?
Do you know your APN setting?

I had the same problem till I ditched TWRP for CWM. My I717 seems to like ClockworkMod better. Just couldn't get TWRP to flash the modem correctly. *#06# will give you the "Null Null" IMEI message if you have the same problem as me. Use Kies to recover and initialize the device, its under "Tools". When done you will be on JB with proper IMEI. Flash CWM through odin and go from there.
**EDIT**
Turns out that the problem I was having might have been because of outdated modem files. The issue is resolved for me with the modems at the following link. 4g lte has never been this fast before these drivers. Fast and stable, be sure to give the OP a thank you.

I've been having the same issue. I started with Stock, went to CWM ver 6, CM 10.1. Decided to flash a modem, and then it would say unknown baseband / no phone number / no IMEI. After trying many modems and restores, I have restored through KIES back to factory as of now.
If anyone has an idea, it would be appreciated.
I live in Florida the only way I get 4g LTE is with stock modem...I used to have the same issue...so I just keep it stock...

Hey all.
I was on MIUI 1.9.2 and flashed VillainRom (wiped everything as usual) and after the reboot, I couldn't get any signal. Went to the mobile network screen and I get an error saying I don't have a sim card in my phone.
My baseband and IMEI all read unknown.
Tried restoring a nandroid with no luck.
Are there any fixes or do I need to send it off to be fixed?

Another problem with Custom Rom!
Anyway, do a Factory Reset, if it doesn't work then flash Stock ROM.

Didn't realise there were CWM modems available. All I've found are for Odin..

This might be a long shot but try toggling airplane mode on, reboot the phone and once fully booted toggle airplane mode off.
This issue has nothing to do with the Rom you flashed, (not VillainRom anyway) it seems in all your flashing you may have messed up your EFS partition, some people got it back when they flashed a stock ROM, if you don't, you may need to get in contact with Odia, he can assist you with getting your IMEI back

Flashed KG3 fully, nothing.
looked inside the KG3 zip again and found a tar with EFS in the name. flashed it via Odin and all is well.
Thanks for your help.

Good for you it worked .
Hi. I just Odin'ed back to stock firmware after experiencing no 4G data, only Edge, after flashing the Tmobile recovery through Rom Manager while on CM9 nightly #2. I had wiped and reflashed CM9, with no luck. I thought Odin'ing would fix the problem but it did not. I also tried removing the SIM card for a couple of minutes. Anyone have any suggestions what i could try? Thanks
Update: So far flashing CWM recovery using Rom Manager has set the IMEI to 0, on mine and MacTheRipperr's phone.
Anyone else with similar issues after flashing recovery through Rom Mananger?

Are you sure it wasn't a Tmobile problem? Maybe you should try other kernels and/or roms... I'm using AOKP on my Galaxy S since february and on my Galaxy SIII since June 19th, I haven't experienced any problems with mobile data, the link is below.
I hope it works.

Check your imei under the phone status. Do you have a 0? If so the same thing happened to me.
Do you have a back up of your /efs from the root?

Thank you for your response. I'm 99% sure it's not a Tmobile problem. I didn't have any issues with mobile data at all. This happend soon after i rebooted after flashing the tmobile Rom Manager custom recovery. First thing it did was give no signal connection at all. Then i reflashed the CM9 rom, which then was only able to get Edge network. Even after Odin'ing do i still only get Edge. I haven't tried a custom kernel yet. With certain devices, I've known of issues with modem's are sometimes fixed by flashing a standalone modem rather than going through the whole Odin process. But that isn't an option that is available for the T999 varient.

Yes it reads 0 and no i do not have an /efs backup. The root process I used was the Sprint root zip file flashing CWM and root using Odin. I wasn't aware of a backup that was made. After Odin'ing back to stock, i did the same root method and have flashed Redrum Lean Stock Mod which im currently on. Where would i find the /efs if this method did make a backup of it?
Question for curiosity s sake did you flask the cwm touch recovery
You should backup your EFS folder before flashing any rom, if you'd lost your IMEI you will have problems with mobile data and/or phone service.
I've found two topics about it here, the first one has a link to recover Tmobile and the second is more general. I hope it works!

You guys are freaking me out about losing IMEI. Thankfully mine is fine after rooted and flashing several ROMs.
How do I backup my EFS folder?
/sigh re-read all the imei threads, there's like 10 of them. Backing up the efs folder will not help you at all. The nv data.bin file is not there anymore and nobody has found it yet. Your only option is odin back to stock, take your phone back to where you bought it, and say this POS broke and i can't get lte even though i paid for it. If you're still under warranty hopefully they will replace it.
Everything has been running smoothly on my T-Mobile Vibrant until suddenly I lost my data connection (nothing was changed on my end). I am able to get a 2G connection by checking the "Use only 2G Networks" box, but when it is unchecked I get no data.
I pulled the SIM card and put in another phone and that phone did get a good 3G signal.
I flashed a new ROM - I am now using Slim Bean 2.6.0 with the KA7 modem. I replaced the SIM card with a new one. Still just 2G and only when that box is checked.
I'm stumped.
Is that the same modem you were using before?

No, before I was using KB5
http://forum.xda-developers.com/showthread.php?p=9734167
You'll find the KB5 modem there if you want it back. Flash it in CWM.
Is data enabled? Dumb question, but it can solve all of your issues. Also, make sure you have APNS.

Sorry, I meant that I was using the KB5 modem before I switched to the KA7, however I don't get 3G with either one. The modem change, ROM change, and new SIM card were all things I've tried to fix the problem.
My data is enabled and I double checked the APN. Sigh... may be the end of a good run for this phone.

Maybe try returning to stock and then re-root, CM10, etc.

Does your IMEI match the one on the back of the phone under the battery?

Yes, it does.
Well like stated above, the next step I would take would be to go ahead and Odin to stock. Reroot with update.zip and flash a ROM.
I recommend trying Paranoid Android. It runs very well. I would imagine whatever is amiss will get resolved.

just re- flash stock (yes stock OFFICIAL) look on the on the general thread. and once done, try boot into recovery and will most likely get into it. Then wipe data (formats SD card) and wipe cache, then reboot and all will be fine. I always re-flash stock TWICE when coming from AOSP/AOKP/CM10 and always wipe data.
Hello, i have a strange problem. My device has no service, but in "status" i get asu (10 for example). The imei is good and its not a carrier or sim problem. I downgraded for stock 4.1.2 and lost root and everything and it wont go. Any answer??

Could be a number of things, you don't give any information so very hard to help.
Which rom have you come from, which version of stock are you trying to flash? Have you tried another sim in your phone, or your sim in another phone? Is the APN and network settings right? Is your IMEI blocked or not matching the one under the battery?
Try helping us and we'll try to help you.

I flashed omega 46.1 and the problem started. I think it messes up my efs folder. Now i run cm10.1 after full wipe and i get signal but suddenly "no service" but i get asu in "network strength". The apn is good also. I changed carrier and sim and the problem remain. My imei match the same imei on the box. Its something with the software im sure. But how can i fix it?

Go back to official stock rom and test again.
I did it. Downloaded from samobile the latest firmware for my country. Lost root and it changed my kernel, modem, system and cleaned it all except sd card.

You've either flashed an EMG based rom, in which case you can only use EMG baseband from now on, our you have corrupted your efs folder.
If you don't have a backup of your efs then you will have to pay for a repair.
