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

Thanks for your help.

Okay here is the problemo
i was running D4v10 with siyah Kernel
I had the dreaded unknown baseband, Unknown Imei last night after my phone randomly rebooted. Thought Okay, ill restore it with helcats EFS tool. didnt fix it.
So next i tried to restore the EFS backup with http://forum.xda-developers.com/showthread.php?t=1308546. That didnt work either.
The phone has been factory reset
So i flashed KI4 generic from Intractech's stock thread and used CF root to go with it and it worked my Baseband and IMEI are restored, However now whenever i flash any new firmware VIA Recovery (GB roms, CM9 and AOKP etc) my Baseband and IMEI become unknown. so basically my phone still works if i use a stock firmware with CF root, but i cannot flash any new Roms via Recovery. Not even LP7 Generic works...
Has anyone come across any similar problems to this?
Also Flashing the Ki4 stock firmware, Nandroid back it and then updating to CM9 doesnt work, however when i restore the backup it works again :S
tearing out hair
i flash my sgs1 an sgs2 uncountable times but i din face pblm,but yes once my efs got corrupted in sgs1 but i had bckup......anyways wat u do first factory wipe,clear cache,cache prtition then do a clean install of stock rom tht ur kies shows not any otha stock,,,then use the correct cf root for rooting an for cwm...check if all is good then install hellcat and make a new image of efs(only if phone is all good)then will c later if ya got prblm

yeah the EFS backup i have is fine. /EFS is also fine. The only way i can get it to work is if i use the KI4 stock firmware. Kernel choice doesnt even matter.

yeah but the efs back up u must have taken wen the phone was good right,an ki4 its gb rom...so u can try flashing as i told an yes kernels do matter m8,cf root the right one later u can enter neak or redpill i don sujjest siyah new versions..an flash the desired rom
Nothing but stock ki4 results in unknown baseband. That is the problem. No matter what I flash or how I flash it, results are the same.
I only managed to get it to work once with efs pro on a different firmware (lp7). The phone didn't reboot and and after a couple of minutes it was fine until reboot.

There's a known 'Unknown baseband' bug when you charge the phone and flash new roms. Take out the battery for 180 seconds. Put it back in. Go into recovery wipe cache, format cache, wipe dalvik cache. Reboot. See if it works.
Will try when I get home and I'll post the results.

So did it work? Having the same problem here.
Reboot with no charger connected, issue solved?
If not, flash another modem (doesn't matter which one) and reboot (unconnected)

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.
http://forum.xda-developers.com/showthread.php?t=1716001
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.
Hi,
I bought my phone on december 2011. It is rooted and I put the Checkrom V6 and the redpill kernel five months ago. For the radio, I think it was the KK5 one, but I'm not so sure. Yesterday, everything was working fine, when I turned it off before going to bed. But this morning, my phone couldn't join any network. In fact, it couldn't detect any simcard. I tried putting my simcard in another phone, and it worked, while putting another simcard in my phone didn't change anything. When I tried the *#1234# code, my phone was "Unknown" and I didn't have an IMEI anymore. I tried to restore the EFS files but it didn't work at all. So I tried to restore an old back up, but nothing changed. When I tried to go back to my latest backup, I kept on getting "md5 mismatch". I read this thread http://forum.xda-developers.com/showthread.php?t=976453 but nothing worked... So yeah, I'm kinda stuck and running out of ideas... Sorry if I shouldn't have post this thread, but I thought I could as I almost tried all the solutions given that I could find. But still, I'm sorry if I shouldn't have done it and thanks in advance if someone has a solution for one or both of my problems...
Try going back to stock Samsung ROM, flash using Odin and see if that works, just flash PDA and make sure repartition ISN'T ticked after that enter recovery wipe data+cache then reboot and then flash siyah kernel for root. Just a suggestion!

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.

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.
