[Q] Problem: IMEI number, serial number, baseband, etc. unknown - Galaxy S II Q&A, Help & Troubleshooting

Hello!
I have a samsung galaxy SII that has lost all network connection (wifi works though). It's just a check of the pillars and cant either call or text.
When you go in and check Baseband it says unknown. Similarly, IMEI, serial number and all network related stuff.
I have searched and found EFS Pro but it did not work following the wizard.
Is there anyone out there who can help me get my phone working again?
Would appreciate any help very much!
Im running CM9 stable by the way.

Restore your EFS backup. No EFS backup (Gee, that would be a shock. Everyone does those ) either service centre & explain what you've been doing with the phone (and hand over the contents of your wallet to have it repaired), or if you contact Odia by PM (and wait patiently for a reply, do not hound him) he might be able to recover it for you.

Have you tried to reflash baseband through Odin?

Please answer these questions:
1. Did your problem occur after flashing in CWM recovery with your phone charging?
1. Do you have a good /efs backup?
2. Have you ever flashed Siyah kernel before?
3. Post screenshots of Settings>About phone, and Settings>About phone>Status on your phone.
thanks

1. I do not know, I got the phone from a friend who had the same problem with it. He ran the phone stock. So I flashed the CM9.1 and after it worked it in about a week and then it stopped working again simply. He bought the phone used so do not know what is done with it before. However, I had the charger when I tried to flash it yesterday, it is something that you should not do?
2. I tried some kind of stock EFS I found, but did not get better for it. Then if you go into the EFS folder in your phone, there are. .bak files are dated 2011 which might be ok?
3.I got it as soon as I get access to the phone.
Thanks for reply!

1. Yes, it has something to do with it. Don't flash in CWM recovery when connected to charger. It's a known bug.
2. I meant do you have a real backup of your /efs .tar or .rar? Check your internal and external SD for anything efs
3. Ok

i have the same problem and have a backup of efs ...it has 5 folders efs,efs-163,198,200,490..i dunno wat to do please help me with this problem thank u

IMEI lost when copying nandroid backup from old phone to new
Beware.
After receiving a new Nexus 5 to replace my cracked but still working one I immediately rooted/unlocked it and then copied my old N5 backup to it. Used WugFresh Tool Kit 1.8.4 to root and TWRP to recover and both phones were at Android 4.4.4 so what could go wrong? (I thought) Somewhere along the way the new N5's IMEI number was lost (=0) and so no service. Tried factory reset and recopying but no luck.
I factory restored the phone and returned it to Google. I expect some penalty for my antics. I will get delivery on another N5 today and will refrain from tinkering for awhile. Fun.
Correction to above: The newest Nexus 5 received today came with Android 4.4.2 not 4.4.4 as I assumed (and perhaps incorrectly) for the new N5 described above. This could have been the deal breaker, copying a 4.4.4 system over a 4.4.2 one, that screwed the IMEI (?).

S2 IMEI Unkown + No Service PLEASE HELP

Hi all,
I own a galaxy s2. I'm facing a issue which i've been trying to fix for the past couple of weeks. I tried many threads in this forum, but nothing seems to solve the issue.
This is the issue,
I used to flash custom roms on my device. I used many custom roms including cm9 RC1 and when samsung released the lastest 4.0.4 update i just wanted to chek it out. so I downloaded the generic russian (SER) firmware and flashed it using odin.
After flashing it I was stuck @ boot. i was stuck there for more than 10 mins, so I ended up removing the battery. then I went to samsung recovery(Volume Up+Power+Home) and cleared the cache and user data and rebooted the phone it worked fine. At this time I didn't bother to check whether my IMEI was there but everything worked fine.
After couple of days(without rebooting the device in that time) I droped the phone. battery came off, when I turned on the device again, prohibited mark like thing came in the status bar and there was no service, when I checked the IMEI it was not there.
At this moment I was not sure whether the drop caused the issue or the flashing caused it. I later realized IMEI issue comes because of EFS but sadly I didnt back it up. After diggin for few days I found when flashing one of the custom roms, efs was backed up automatically, I tried restoring it, but it didnt help (Maybe the backup was corrupted )
I followed various threads in this forum but nothing helped me.
Please help me get the IMEI back, I really miss my device :crying:

I once had a similar problem.
My imei went lost because of a rom upgrade and I DIDN'T have a backup..
I solved the problem by flashing a stock rom (any samsung stock rom will do) with ODIN.
I am not sure what happened, but it looked like that the nv_data folder was "re-generated" and I got my IMEI back.
Now I have a copy of the folder in every storage media around my house

If you have a backup, then you should be able to recover it. There are tons of threads on here with instructions on how to restore an EFS backup. Search (if you want it fixed, that is. If you don't want it fixed, keep posting to this thread in the hope someone spoonfeeds you. Might be waiting a while tho).

I tried almost every thread here in xda about restoring, tried GSII_repair, kTool to restore it but none of them recovered the IMEI. I did not made a backup of efs but when I installed the Hydra H2O ICS Rom for GS2 it made the backup i guess, because a file called "efs-backup.tar.gz" was in a folder called .hydra inside the sd card.
does the drop of the device has anything to do with the erased IMEI?

I have installed stock roms from samsung using Odin, but then I discovered that efs folder get unmounted everytime I install the stock rom, phone just starts after flashing without android setup wizard, also when I long press power button, menu wont appear, device just shut down, after I restore the efs from the backup i have, and mount the efs using the CWM recovery would bring back the power button long press menu. everything else working except for Mobile Networks. and imei/baseband shows unknown
Drop Caused this problem
Hi all,
Thank you for replying on this thread and helped me figured out my problem, I have contacted Odia and he thinks that dropping the phone damaged the baseband chip inside the main board, not a flashing of the roms or efs folder issue. i have only 2 options either replace the whole board paying LKR 35,000 (New s2 costs only LKR 65,000) or use it as a MP3 player :crying:

Need original IMEI help

Hello everyone,
I'll admit, I flashed a CWM touch recovery to my phone believing it was meant for it, turns out after CWM flashed it that it read something about Nexus 7 touch recovery successfully installed. I was like "NO!" Since then I had to restore my /efs directory from scratch. Only I still have one problem. I have a generic IMEI and AT&T suspended my service. I called them to restore it, giving them my real IMEI from behind the battery. Service came back on immediately after they confirmed it on their end however my phone still shows an incorrect-generic IMEI. How do I get my real IMEI programmed back onto my phone again? All help is appreciated. I'm currently running a CWM/SU injected stock ICS ROM.

if you are stock ics i'd just odin back to stock ukk6 or whatever it was (gingerbread). Just for a fresh start and see if that helps...other than that i have no idea.
Update
I've done enough searching to understand somewhat that this relies on the nv_data.bin file that is located inside of the /efs directory. I've gone in to look at the file through hex editor and have managed to change the model number back to my correct one (SGH-I777, it was showing SGH-I897Z or something before). My best guess is that the data in this file is either showing the incorrect IMEI but I just can't figure out which hex line it is so that I can go in and change it. If anyone beats me to the punch please let me know! Hope this helps someone else out too!
Going back to stock may help. I guess all you can do is attempt to restore your /efs again. I was in a similar situation (generic imei due to an unlock tool) and ended up having to get warranty repair. I had several /efs backups and attempted to restore it using numerous methods: all to no avail.
It appears that your options are as follows.
1. Keep attempting to restore/repair /efs (tons of threads around on it) using multiple tools. The key lies in the nvdata.bin file.
2. Samsung Warranty Repair
3. Mobile Tech Videos repair
4. AT&T insurance replacement may be an option?
Just a few questions then...
1. Will flashing to stock 2.3.4 2.3.6 overwrite the /efs directory to where it goes back to stock too?
2. Is there any harm in leaving the generic IMEI in place?
I think I'll close this thread after this.
Thanks!

1. It might work; didn't for me. I've seen it suggested numerous times around /efs threads.
2. Not really. Carrier-wise? Yes. Once AT&T blocks it, there's no way around keeping it in place; you won't be able to use it. I've also seen people report that PC market installs were wonky or occurred randomly from other origins (as a result of having the same imei as other devices).
have u tried this guide yet? as long as u have the original shipped EFS folder this should work. http://forum.xda-developers.com/showthread.php?t=1264021

No signal problem

I got a S2 yesterday. I flashed Siyah on it to get root and CWM and then I flashed the newest supernexus rom. Everything was working fine, I had signal, and I could call and send messages. Yesterday in the evening I got no service message. I thought its going to be temporary so I let it be. This morning, I woke up and I still had no service and signal. It just says "emergency calls only". My IMEI is not gone though. Can someone please help? Any help is appreciated.
'Got' an S2 from where ? Check your IMEI in settings/about phone/status, if it's correct (don't post it here, whatever you do), then I'm tipping it's a carrier-side issue (blocked IMEI or something else), so call them first. If your IMEI is the generic one (0049....), then you have problems.
UPDATE:
I tried GetIRL because I though it will work, and it didn't, and now my phone has lost its IMEI and when I turn it on it doesn't ask for the SIM lock code. HELP!
You're a fool
I hope you have an EFS backup.
Edit - Any other n00b reading this thread, this is what happens when you don't know what you're doing. You 'break' your phone. And this is why you search/read/learn/understand stuff before you do anything to your phone.
And what if I haven't?! I have a EFS backup from my old phone, Samsung galaxy s, and I remember there was a way to get it back on that one. There isn't a problem without a solution.

From CM 10.1.3 back to stock ROM, IMEI failed

Hello!
Today I decided to go back to the stock ROM of Samsung S3 (international).
So, I downloaded the original from sammobile :
http://www.sammobile.com/firmwares/3/?download=16458
Went into the Download mode of my phone:
With Odin3 (v3.07) I loaded the .tar.md5 file which I just downloaded. (by the PDA ofcourse).
Then my phone restarted and just follow the steps as you just get your new Samsung S3, like account configuration etc etc etc.
Did the tutorial to reset the flash/binary counter, just worked.
After this, I was planning to install Whatsapp again,
THEN noticed I had no network signal , except WiFi .
Probably there was no signal when the phone already got started.
I checked *#06# for the IMEI, and there it is.. the 004999xxxxxxxxxx / 08 .
So, I've checked some topics and tried a thing that should repair the IMEI.
But no success!
When I installed CyanogenMod, they didn't told me to backup the EFS folder (or I just didn't see that at all!)
So, I followed this topic:
http://forum.xda-developers.com/showthread.php?t=1264021
Didn't worked.
I'm root again btw on the stock ROM.
Then I noticed I've a backup of my phone BEFORE CM. Made it with the CWM itself, which I moved later to my computer.
So, I moved that one back to my phone. and when I go to CWM Recovery and select Restore
It says:
Couldn't open directory.
No files found.
So, checking for that error, someone came up with moving the backup files to
/data/media/Clockworkmod/backups/
Did not work!
What to do?
I'm questioning myself now, even if the restore is going to work, will the IMEI be restored too?
EDIT: Monday it will be shipped to Samsung.
- Back to stock
- Reset flash/binary counter
- Unroot
- Wipe cache and back to factory
Couldn't get rid of the 0049 IMEI and 0000000 S/N
I'll keep this post up to date when I hear something.
No CWM does not backup efs....I suggest you go here http://forum.xda-developers.com/showthread.php?t=2393289 because they will close this thread soon due to this question being asked many times before
I've seen that topic indeed, then I will put it back with flash/binary count to No , and the status to Normal.
Hope Samsung will fix it then when it just doesn't work.

Flash via CWM. If you don't want to flash it via CWM you can also extract "modem.bin" file and flash as MODEM through your Odin.

Thanks for your reply!
I've set everything back to stock and reset the counter/binary to No , and the rest Samsung official again.
Today I went to the shop where I bought my phone, and they're going to sent it to Samsung.
Forgot to mention here that my S/N is also 0000000.
Let's hope that they will repair it.
I've red a news article, that Samsung has a new policy.
They now also repair rooted devices and even when a custom ROM was installed.
I'll find out when I got a message from the service centre.
When I know something, I'll post it here.
Thanks again anyway!
Should have tried your modem.bin
I've red a news article, that Samsung has a new policy.

Doubt that but just in case do let us know if Samsung reject warranty .

Did you read the IMEI / EFS post on the general forum?
I had a similar problem... to make the story short before CM 10.1.3 I was on stock MG4, after CM I decided to go back to my carrier's stock ROM (needed to send my phone for repair, USB port was faulty) and I noticed the IMEI problem. What happened is that Samsung decided to change the efs format with MG4 (July 13th) so any rom prior to that won't be able to read the efs.
If your rom is prior to that then you need to flash a newer modem (MG4 or later) so it can work properly.

Yeah, I must have red over that... But I tried fixing it spending about 10-12 hours on it, cuz of searching and read it carefully.
I had no EFS backup, stupid that the CWM Recovery didn't backed that up , and of course, stupid of myself :silly:
I will now wait if Samsung is going to repair it under my warranty.
If not, they will probably call me about fixing it for a price.. (If the article isn't true about repairing rooted / flashed devices)
Update 15-11-'13
Phone is repaired under warranty!
They reprogrammed the phone and did a software update. I'm not sure if this is the 4.3.
Can pickup my phone monday, because the shop doesn't receive delivery on saturday -_- ..
But at least, it should be working fine now.

[Q] S5830i strange rom flash imei issue -Need kind assistance!

Hello.
I really didn't want to make a thread but i've been bouncing of dead lnks and failed search results or outdated incorrect info all day and i can't seem to get the information i need. I'm sorry if i haven't done everything i can before this psot but i have rtied, i really have!
My issue:
I have a Samsung Galaxy Ace GT-S5830i which was running so slow it was terrible. I found a nice slimline rom that i read about and was happy to use.
I used Samsung recovery to then run CWM ClockWorkRec5830i, which i used to install 'update' which gave me Superuser access and rooted my phone (i think, if i understand) then i made a backup of my phones stock image, then i used it to wipe the phone, clear cache, and finally install my new rom.
...so far so good.
The rom installed, the phone rebooted, everything was working (really fast and really well, i was VERY pleased) however i have hit my issue:
IMEI data was gone. *#06# showed nothing, so i went back into Samsung recovery, loaded ClockWorkRec5830i and restored my phone back ro original using my backup. The IMEI returned! All was well again, so i got Galaxy Toolbox from Play store, ran it with Superuser access and created a backup of the EFS file.
I returned my phone back to the new rom that i had chosen and again installed Galaxy Toolbox to use the 'restore EFS' option.
The IMEI is still blank using *#06# which has me very confused.
I can open the EFS backup file in Hex workshop and the serial number data is is there. I can use Galaxy Toolkit device info and see the IMEI in there, so i don't understand what i have done wrong for the IMEI not to be showing in the phone.
Can anyone help or educate me please. I do generally want to learn more about why i haven't realised the mistake may.
I love learning this stuff but it can be overwelming sometimes until someone comes along and calls you an idiot and tells you the obvious lol! Please, "I'm an idiot" hehee.
Thankyou

Don't consider yourself idiot at all lol. You have explained everything so clearly.
Well,
This problem is so much common with this phone. Don't know why !
Many people including me facing this problem.
Sometimes you just reboot your phone and you will see ur IMEI is gone. Reboot again and its back. -_-
Its really strange issue actually.
You already knew all methods to get IMEI back. This is comman issue with this phone. Suffer it.
Maybe @iamareebjamal have figured this prob out.
Sent from my GT-S5830i using Tapatalk 2
The rom i found was great. It performed so much faster, did not take up much of the very limited memory on the handset, it was the perfect solution to my needs but whenever i use it i cannot make any calls etc due to no IMEI (*#06# shows a complete blank box) and i have tried rebooting the phone so so many times, repeating the process of installing the rom again and again and not once can i ever get it to show IMEI in *#06#. I could understand if the EFS backup also showed that the imei had reset or become corrupt, but it looks fine in Hex Workshop, shows up in device info on Galaxy Toolbox app, i just can't conclude anything from it's behaviour.
Using my original phone's backup the IMEI is restored instantly, and i have taken the EFS backup whilst running the phone on it's original state.
Could it be because something is not right in the rom? Is the rom changing something that i could possibly correct myself? Or something in the rom not suitable for my model and version of the GT-S5830i handset (compatibility issue)?
I really want to be able to use this rom and other's seem to be able to use it without issue which just makes me more determined to find the cause and correct my issue. I also see that many people do lose their IMEI and the EFS backup/restore method seems to work perfectly for them, because they seem to have their IMEI turned to blank values when checking in HexWorkshop whereas mine is still showing as expected.
I cannot make sense of this scenario at all lol.
I appreciate ANY and ALL advice
The rom is was trying was MEHDI ROM v2. I am in the United Kingdom using a GT-S5830i on o2 newtwork with no network locks or restrictions.
Make a new backup of your IMEI(make sure it is lost by once or twice rebooting) . And open via Hex Workshop.
If you see your IMEI in there, then reflash stock ROM and flash this Custom ROM without wiping anything.
If it doesn't solve your issue now too
Try restoring the efs partition before Media Scanning starts and Reboot the phone after media scanning is started.
These all are hit and trial methods. I've myself never found a fully satisfying solution
If nothing works, you'll have to try any other ROM.

Hello.
I really didn't want to make a thread but i've been bouncing of dead lnks and failed search results or outdated incorrect info all day and i can't seem to get the information i need. I'm sorry if i haven't done everything i can before this psot but i have rtied, i really have!
My issue:
I have a Samsung Galaxy Ace GT-S5830i which was running so slow it was terrible. I found a nice slimline rom that i read about and was happy to use.
I used Samsung recovery to then run CWM ClockWorkRec5830i, which i used to install 'update' which gave me Superuser access and rooted my phone (i think, if i understand) then i made a backup of my phones stock image, then i used it to wipe the phone, clear cache, and finally install my new rom.
...so far so good.
The rom installed, the phone rebooted, everything was working (really fast and really well, i was VERY pleased) however i have hit my issue:
IMEI data was gone. *#06# showed nothing, so i went back into Samsung recovery, loaded ClockWorkRec5830i and restored my phone back ro original using my backup. The IMEI returned! All was well again, so i got Galaxy Toolbox from Play store, ran it with Superuser access and created a backup of the EFS file.
I returned my phone back to the new rom that i had chosen and again installed Galaxy Toolbox to use the 'restore EFS' option.
The IMEI is still blank using *#06# which has me very confused.
I can open the EFS backup file in Hex workshop and the serial number data is is there. I can use Galaxy Toolkit device info and see the IMEI in there, so i don't understand what i have done wrong for the IMEI not to be showing in the phone.
Can anyone help or educate me please. I do generally want to learn more about why i haven't realised the mistake may.
I love learning this stuff but it can be overwelming sometimes until someone comes along and calls you an idiot and tells you the obvious lol! Please, "I'm an idiot" hehee.
Thankyou

As about these issue i do flash a Custom Kernel after flashing Rom with no IMEI Number
So After Flashing any Custom Kernel my IMEI Gets back
You can try it with any kernel

try any custom kernel...it helps me every time..
i have wiered problem, i can't use custom kernel on stock rom...or stock kernel on custom rom, both of these combination makes my imei disappear every time.

Hey, did you solved your problem? i had the same problem once and it was just that the backup made with galaxytoolbox didn't match. So the best solution is to do a backup again and you will have to open the new file and edit it with the HEX editor and input your imei number manually. Here the thread with the info http://forum.xda-developers.com/showthread.php?t=2064034&page=1 and this video is great, but it's in spanish. http://www.youtube.com/watch?v=1kbY0EZYsXE Hope this solves your problem.
I cannot use the galaxy toolbox for my restoring unfortunately as the galaxy toolbox is not working with my current rom, if you know of another program that can help me fix it, i would appreciate it.
Thanks,
Fab

Thanks for the replies, but unfortunately i have not yet resolved the problem.
I have gone over the process again and again, repeating it the same way, trying slightly different ways, the outcome is always the same. Everytime i try i take a EFS backup (taken while the phone is restored to running on it's original stock rom and setup, with the IMEI all working and displaying via *#06#) the EFS file shows the IMEI in Hex Editor. Everytime. It's always there.
Then, as soon as i flash a rom and reboot the phone i have no IMEI. I use the good EFS backup and restore the EFS to the phone (which has the IMEI data intact) but the phone still will not display the IMEI via *#06# and if i check the EFS again it is still showing the IMEI as being in the EFS backup and still good.
So i have no idea why the phone is not seeing the IMEI because apparently it IS still there!
I'm installing roms by using the recovery method to 'apply update', using Samsung basic recovery mode, but could i use the CWM recovery to install? Would that have a different effect? Is it safe to use CWM to install roms as the guide i read said to only install roms using Samsung restore as CWM adds a risk of crashing or bricking the phone?
So many people are able to successfully flash a GT-S5830i and i just do not know enough yet about phone roms to feel confident to do more daring things with different methods for fear of making a critical mistake. So much of the information i have read contradicts itself, and other information neglects to explain certain things or simply assumes you know about bootloaders, CSC files and the like...
I've modified so many gadgets before and am fairly confident with doing such things it's just i can't seem to educate myself correctly over the modifying of these Samsung Android phones.
I just bought a Samsung Galaxy S GT-i9000 today and wanted to remove some of the bloatware so that's my next phone to read up on.
I have been put off a bit because of the issue of losing IMEI. It seems to be a big risk with this model, do other Samsung models have issues with IMEI loss?
Thankyou to all who are taking time to post. I read and appreciate every post, and am enjoying learning about this new topic to me.
Perhaps i shouls restore back to my original working setup, then install the rom using recovery (or via CWM recovery - i have no idea which is safest and the correct method as i read conflicting information) then install the rom without resetting/wiping anything? Would that help?
When i select roms should i be making sure they contain a compatible baseband or something?
I don't understand this area.

About recovery use CWM
If you do not wipe then there will some problem occur may be like the phone will not boot after flashing Rom so must do wipe
And about baseband and all don't worry you can use any stock Rom for flashing Roms.

I'm not sure if you missed this step.
I did efs backup on stock rom and tried to restore with galaxy toolbox on the new rom and IT DIDN'T WORK....
you have to copy your imei number manually (or directly from the sticker) and once you are in the NEW ROM, make a backup of the IMEI. of course if you open it with the hex editor it will be EMPTY.
Then in this new back up file newly created you have to manually input your IMEI number using the HEX EDITOR.
This should work.

Don't ask the same question in two different threads.
Galaxy toolbox works almost every time.
Did anyone having a similar issue manage to resolve it or can suggest other steps to follow?
I am having the exact issue but for the life of me can not make the IMEI appear even though galaxy toolbox reports it is fine. Here is my post from another thread, before I found this one.
Flashed ROM, all working fine except as above, no network connection (mobile connection). Wifi, etc all working. IMEI is blank when I do *#06#
Have tried
1. reboots, sim out, reboots, etc
2. tried using galaxy toolbox to backup imei/efs and then restoring after flash. nope no help.
3. tried backing up imei and editing with hex editor but the image already has correct imei. galaxy tool box does report correct imei.
4. just tried flashing rafel kernal using instructions but after doing so, phone does not boot past samsung screen.
5. reflashed back to stock room and crap radio still not working lol
so any suggestions? i need a kernel and then one that works with this rom.

Since the above, tried thunderbird kernal and I am still without IMEI.
I would just like to ask. Is it possible, at some point I have deleted EFS partition? Should I be able to see this EFS partition somewhere? Browsing through PC, on SD card or through CW recovery?
My only idea is that I have deleted efs partition so galaxy toolbox has no where to restore to BUT the app itself reports correct IMEI as does the hex value with a backup file.
Ideas, rants and possible suggestions welcome!
Thanks
