Im having an issue after flashing my phone to GB 2.3.3 my service cant be recognized under the about phone gives me the correct os and build but the baseband and IMEI are unknown. I followed these steps correctly and i cant figure out my problem. Link below is what i used.
http://androidadvices.com/how-to-update-samsung-galaxy-s-4g-to-gingerbread-2-3-3-firmware/
did you back up your efs folder?
this problem more than likely pertains to the fact that your efs folder got wiped somehow during the flash the only way to fix it is with the backup
Yeah i fixed it! thanks
I just had this happen to me but I don't have my efs folder backed up. Will a nandroid backup fix it if not how can I unroot it so I can send it into tmobile?
Edit: Didn't work I'm going to have to unroot this I have KB5 on now since it was the only froyo non deodexed rom I could find but I can't seem to get superoneclick to unroot it.
Edit2: All I need is a rom suitable for turning the phone into tmobile to get an exchange done.
Is there anyway to get the the unknown IMEI and baseband back to normal and if not can someone please help me unroot the phone because superoneclick isn't working?

This didn't resolve my issue still no signal, baseband unknown, and IMEI unknown. I also used kd1 as my froyo.
Flashed on stock nondeodexed KB5 and unrooted it with superoneclick so its ready for handset exchange.
i just bought this phone on craigslist and its having the same baseband unkwon problem has anyone figured out a fix for this yet?

Is it just the baseband or do you also have a missing/unknown/bad IMEI?
Battery pull for 10 min or more? Other threads on the same topic suggest it.

Guys, you may want to try this before going forward with anything hard...
So, this same thing happened to me. I had Valhalla Black flashed on my phone, it started to glitch (reloading the home screen every 3 seconds or so and not loading any apps), so I did a CWM restore and it went into a boot loop (the splash screen would freeze and never load the ROM).
So, I used Heimdall One-Click to flash the stock Gingerbread ROM, and my IMEI/etc were all unknown. I saw all these options to use hex editors and stuff to redo the nv_data.bin file and was just about to do them...but...
I decided to check and see if it was the SIM card that went haywire. I put the SIM into another phone and the phone ended up getting service, so I thought, "Oh, sh**, I'm screwed...I'm going to have to do all this IMEI repair stuff..."
In the end, I put the SIM back into my t959v after taking it out of the old phone I was checking it with...AND BAM, IT WORKED! IMEI and everything are back and I'm getting service.
Point of the story: check your SIM card in another phone and see if you get service, then put it back in your other phone and see if you get service again.
FU** YEAH!!! No tough stuff afterall! Reflashing Valhalla Black and restoring apps, settings, etc. from Titanium...
I was running slim 4.2.1 for quite some time with no problems, i loved it. I flashed 4.2.2 and my phone got stuck in NV and my phone number would come up as 000-000-3370. On first boot everything seems to be fine except that i get an error when i try to open up the play store. On my next boot is when I would see these problems. I tried everything from dirty flashing from a working 4.2.1 rom to completely formatting everything, even my external sd, and the same thing happens. This happens with every 4.2.2 rom out there. When i reboot i get stuck on the activating screen and my phone will get stuck in NV and ruim/sim wont stick no matter what i do. i don't know what else to do. someone please help!
It isn't a rom issue it is an S 3 issue that randomly occurs when flashing ROMs. You will have to flash the stock rom and reprovision your phone. I know because it has happened to me twice and both times it was with a Touchwiz ROM. You should have backed up your IMEI just in case this happens.
my imei is backed up. but why is it only 4.2.2 roms that do this?
I was able to flash back to a 4.2.1 Rom, namely pure Google for now, with no problems. but when I flash any 4.2.2 Rom the same thing happens.
All 4.2 ROMs used to do this to me.
However.
Only also happened when I flashed miui.
Now I run liquid smooth and haven't had the problem since.

God bless the American people!
do u guys think I should Odin back to stock, then root, unlock, and try to flash 4.2.2?
Actually, there is an easier way
I have had this happen numerous times and it lef me to mess with my phone a little bit. I originally thought that setting it to CDMA/SIM and then rebooting would fix the problem, but I found a simpler solution to that. The last time I encountered the problem I simply set the phone to RUIM/SIM under mobile networks and then Turned on airplane mode for a few seconds then turned it off and I found my number under phone settings and everything. Try that and let me know how it goes.
Edit: Sorry, the term is RUIM/SIM, not CDMA/SIM. My bad.
hmmm, I'll definitely give that a shot later on tonight.
well I tried it, it works. but only temporarily. once I reboot it reverts back to how it was. any other thoughts?
anyone?

nope, none of that works either. no matter what I do ruim/sim will not stick on a reboot on any 4.2.2 Rom. I'm really getting frustrated with this.
no one has any other solutions for me?

Does your phone display an IMEI number?
Settings->About->Status
Don't need the number, just to know if you have it there....
Also do you still have Root/Unlocked bootloader?
yes, i have an imei. i lost it once before so now its backed up, i'll never make that mistake again. it was a nightmare trying to get it back. and yes, i am rooted and unlocked.

Have you done a complete factory restore through Odin? You would lose root and unlocked bootloader, but it may be faster to restore to stock, and reroot/mod than to try to find an "easy" fix. I was having some issues the other day in between a few ROM's, but I just factory restored, and restarted from "scratch". Now I am running perfect.
You may have already tried, but on page 1 you asked if you should, and I did not see a confirmation you did so.
Had the same problem... And yes, the phone must be reprovisioned. Although sometimes you can just adjust the network settings and change it from NV. That worked for me also.

I flashed root 66 via Odin, bootloop. flashed the ma2 stock image, bootloop. then flashed the lk3 stock image with success. but still with the same results as before.
tomorrow I'll try flashing g1 and start from scratch there. what do u guys think?
well, I odin'd back to bone stock G1, rooted with rootdebugfs, flashed cwm with ez recovery, unlocked my bootloader with ez unlock, flashed liquidsmooth 4.2.2 rc2 and guess what. same ****!!!!!!!!!!!!! i'm really getting fed up with this. someone has to have a solution to this cuz this is really pissing me off.
Okay, I had upgraded to 10.1 Aries and it was working fine and I tried changing some things with UOT kitchen and I got a "no service" problem. I have tried reinstalling from stock a couple of times but it doesn't make any difference. tried flashing a different modem and that didn't work either. The phone boots up and wi-fi works, but not the phone or data. Tried flashing an efs restore file and that didn't work either. Bill's paid for tmobile. I tried restoring from a nandroid backup and there is no change. IMEI is all zeros IMEI SV is 02 mobile network state is disconnected.
what to do?
Flash back to stock then reflash cm10.1
I use this one click to restore my IMEI/service issues

Flash CM10.1

er... I flashed back to stock about three times and it didn't make any difference. I used Odin to flash KC1, then KJ6, then a kernel with CWM.
Have you upgraded from a GB ROM to an Team Acid ICS ROM? Their upgrade script automatically backs up you efs files.
Try extracting the tar file from the backup and taking the contents and stick it in the efs folder. That worked for me once :/ there is also a script Team Acid posted per my request somewhere in the Stupid Questions Thread.

Flash back to stock then flash aries release 3. Next time u get the no connection turn off wifi and just wait longer. Sometimes it just takes a bit after boot. Reflashing the modem (make sure you are flashing fb padded modem). That should do it. I started reflashing a modem after aries every time then realized i just had to wait an extra 20 seconds after booting up. Release 3 pretty good with this

I have the same issue. Had been running Aries beanstalk since it came out, switched to dao's pacman and after a couple days it seems the radio chip quit or something. Tried different modems, restoring nandroid, flashed back to stock, went and got a new Sim card. Nada. So... Yeah I had to pay 5 bucks for a new phone lol

After doing more testing.. Kb5 and kc1 dont flash... You need to flash kd1 and up and make sure they are padded.

And if u do install aries then flash kc1 by mistake it will say baseband unknown imei unknown.. But you dont have to do one click.. Just flash padded kd1 ki1 lb6 anything besides kb5 and kc1. I think it has to do with byte size of modem file.

I don't remember exactly where but there should be a folder on your SD card with all the efs backups created when you upgraded to mtd.
The filename should be efs-backup.tar and it could also have numbers in the backup name

I tried restoring from some other efs backup but I'll look around and see if there is any more backups. I have the sd card saved on my hard disk as well. There should be several backups. Somehow, though, I don't think its the imei or 10.1 is storing the IMEI in a different place or folder. This is too bad because the Aries version of 10.1 is really nice.
I pretty much have the same problem. After upgrading to 10.1 I can't get any reception even though I tried flashing stock and padded modems on 10.1.
i found several efs backups in the backup folder, but expanding them and replacing the efs folder on my phone makes no difference at all, IMEI is still 00000000 ..... unless 10.1 uses an efs folder in a different location that is. This is acting like there is a second backup location for the phone information that,if you don't delete it or overwrite it, restores the bad efs informaiton.
Nvm... deleted.

Does anyone know whether the imei information is located in a different location with MTD roms? I have been using the efs folder.
back on my old Galaxy Apollo for the time being -- they are still developing for this phone. Must be a lot of them out there.
I have the same problem. I was using Aries 10.1 just fine. Everything worked great. Then all of a sudden I get no signal. I tried restoring back to stock oneclick w/ factory reset several times. I have an EFS backup which I've restored several times both manually and automatically. No signal, no baseband version, no IMEI. It says unknown on settings for IMEI.
Any help would be greatly appreciated.

You can still get signal with an unknown imei it will just take a not longer the first time to connect. I know it isn't a fix but just a thought.
No luck here. I let it sit for 30+ minutes.

Also worth nothing that while on CM7 I tried every modem without any success. And I did try doing the oneclick back to stock with the same outcome.
I tried flashing cm one day and after hours of not being able to connect to the network I realized my imei was deleted. I restored it flashed back to paranoid 4.3 but have been having connection issues. Next to no service in my house and places I had 4g I have 1 x or searching for service. I noticed my prl is 0, imeisv is 0 and also my eri set to 0. I flashed back to stock and everything was fine but as I excepted ota to upgrade firmware the mentioned above went back to zero. I believe I didn't do something correctly it's more than bad reception. Any ideas?

So, to clarify, on stock you have normal connectivity and the imei and meid is present in settings>about phone>status?

I'm completely lost I have a feeling I didn't do something correctly when I restored imei. Either in qpst or In hidden menus on the phone. I just tried going back to out the box without any firmware updates and I have the same connectivity issues

Restore from a previous TWRP or CWM backup. I had the same problem before and restoring a backup was the only thing that worked. I even tried manually restoring the IMEI through QPST without any progress.
I'll give it a try thanks

For whatever reason I can't access my back ups. In twrp I go to restore and folder is empty. My back ups are on my sd card which I've used several times before. I tried going into install then go directly to that folder but nothing happens just goes into sub cater gory. I'm so lost this seems to not be a common issue so there's. Of a lot of info out there

I recently got through this issue too. After fixing my IMEI, ERI and MEID my phone would recognize a network but could not make calls. What I had to do was ODIN back to a stock unrooted ROM then complete a factory reset from INSIDE THE ROM, not from recovery. Reflashing a nandroid from recovery wouldn't work and simply flashing to a stock ROM wouldn't work, it was only after doing a factory reset using the ROM (Menu->Settings->Backup and Reset->Factory data reset) that I got connectivity back fully. This might work with a Touchwiz rooted rom but I don't know for sure. Obviously after that you'll need to re-root and re-flash whatever ROM you want or restor from a previous saved backup. ABSOLUTELY backup your IMEI information, if I knew what I was doing the first time and knew how simple it was and how little time it takes I would have done that first and avoided all this hassle!!

Sorry I fell off the map on this, life's been busy lately!! All the links to the files I used are infact down. Were you able to get your hands on a stock rom? For all the repair work I used CleanROM, but I only flashed a stock ROM to do the factory reset. I'm actually wondering if doing a factory reset from the menu in CleanROM will do the same thing. Do your research so you don't brick your phone.
I went and looked on my computer and saw the file I used for a stock rom was a Root66 (pre-rooted) ROM.
For what it's worth, here's the links I used:
I started with this return to stock guide. Step three led me to this guide to flash a stock rom using ODIN. Step five of that guide had the links to the stock ROMs and stock pre-rooted ROMs. I was having trouble downloading a 4.1.2 ROM so I used a 4.1.1 instead.
If you still need a stock ROM let me know and I'll find a way to get the one I used to you.

Hey, no worries.. Life is much more important. Thanks for responding. I did get fixed.
I went back to a 4.1.2 ROM, couldn't fix everything. Eventually got back to 4.0.4. Got everything straightened out. And backed that _ _ _ _ up.
Was than able to upgrade to 4.4.2 aosp ROM, of course without needing the backup. But I have it.
Thanks again....as is usually the case, not reading enough up front did me in. Let that be a lesson kids.

Hello XDA!
I've got the I9105P version, and after I've flashed a few rom's, I saw that my IMEI is changed to 0000000000. Although, I can make phone calls and have data connection on my phone. How could I restore my original IMEI? I have it on the back of the phone, with the serial number along.
Please help me!
Thank you!
Hello,
You can try and restore some backup if you have one, It should solve the problem.
If you have a EFS Partion backup, would be better.
Meanwhile see this 2 link:

Best regards,
Thank you for replying, but I already did what's in the first tutorial. The problem is that when I flashed a custom rom, I didn't knew that I have to backup EFS files(noob). Now, after reading and reading, I know that this is important. I reflashed my stock Rom 4.1.2 and nothing, and then reflashed 4.2.2 ultimate update from sammobile, and still nothing. Is there any other way in restoring my IMEI?
Hey guys! I search a lot in the forum, but unfortunatelly, I don't have the NV Data files in my EFS folder. I think the only solution is to get the phone to a gsm service, that has a Octopus Box.
If you think that I have a solution without this, text me
