I'm still with my broken SGS3 mini (GT-i8190) using it only for computer. I cannot make any call or something like that, so the internal signal doesn't work.
My phone broke about a year ago (IMEI null, not generic; Serial Number modificated; unknown baseband). This happended when I tried to flash the thirth time the ENOX ROM, and a couple of days after the phone begun to run slower, and 4 hours after (during the same day) the phone have frozen and didn't boot anymore.
Then I tried to flash (stocks ROM, stocks ROM with root, CM, Carbon ROM, etc...) and I cannot regenerate or recover the IMEI/SN/Baseband.
I have not any box to try to fix my phone, and I cannot buy one (a lot of money for me just now).
I thought that if it possible a thing, I would like to test but I don't know if it's possible.
I was thinking in take a entire EFS folder from other device SGS3 mini (same model, no L/N) and try to edit the files that contains the IMEI information and this thinks with hexadecimal editor. It would be possible? Or it's stupid try to do this? I don't know... **** (sorry).

Yes your EFS is broken. EFS is a partition and not just a folder You can backup a EFS from a another s3 mini and restore it to your one but you will get signal problems example WiFi because same MAC address) and the other s3 mini too. You should know the IMEI number is NOT saved in EFS partition, the real IMEI is saved in a hidden partition so it means you didn't lose your IMEI. But your IMEI security key code (it's saved in /efs>imei) is gone and it means you will never get access to your IMEI number again.

Thanks for all...
Imei is probably stored in CSPSA partition which is mmcblk0p9. I can see my serialnr in there and referees to modemfs, but the rest is encrypted.
I started to look at this a bit closer today to see if I can find out how this all is put together.(efs/modemfs/CSPSA).

Hi there,
I have a galaxy S I9000. The IMEI i have on my phone when i press *#06# is 004999010640000.
I have NO backup of the EFS folder. Sure.
However, I know the IMEI has it is written on the back on the phone.
How can i restore that?
i have to say that i tried downgrading using ODIN... phone is ok in download mode... I did a lot of research but no luck so far.
Thanks
Hello to recover your IMEI you have to flash a stock 2.3.6 ROM and then backup your EFS folder.
After installing new version, if the problem is persist then restor simply your EFS folder.
Hi Higgins91
Thanks for your answer. With all due respect, I dont think it is a correct solution as I tried it and it did not work.
However, maybe before reinstalling the Stock 2.3.6 i should have tottaly delete the EFS folder (the one with the wrong IMEI). Then the Stock "could" recreate the EFS with the correct IMEI on the phone... (thats only what I did read in another forum - But I have not tested).
Luckily I found my previous EFS backed up. (I thought i never did it, but i did 2 years ago ehheh).
Subject closed, even if there is no real bullet proff solution for that.
Thanks
theres athread in here somewhere about that sorry cant remember where read it about a year ago and if it wasnt here it was on darkyrom Q&A maybe
Hello, I lost IMEI data from my i9305 :\
Trying to fix it whole day, but I give up now, im done.
I tried several guides (sammobile.com/forum/showthread.php?t=15196) but nothing helps.
Basicly biggest problem I face is that when I dial to *#7284# it shows "Network is not avilable" so nothing happens, or with another method with removing EFS folder, after backuping it at SDcard1 I have no .nv_data file to modify it and fix everything.
I use SentinelROM v6.0, I tried installing some modified modems, but it was retarded from me. I installed one from orginal firmware today meanwhile I was trying to fix IMEI :\
Can anyone help me?
@edit
I dont have backup. Imei and baseband - unknown ;(
I also would like to add that I know my imei (have it written down :3), but can I somehow rebuild efs based on it :3?
I feel so lucky, I flashed orginal firmware through odin and everything is fine now I just need to upload 4.4 again, and make backup for future!
That was my lesson :3 Thread can be closed.
Earlier this week I had an unsuccessful install of the alpha CyanogenMod 13.0 rom - didn't want to be encrypted so I substituted the latest HC M kernel. wasn't the first time I couldn't get a new rom to boot so didn't initially think much about it but following that flash I couldn't get any new rom to install and successfully complete setup. Each try would get stuck at step right after wifi was set up. I eventually determined there was an issue trying to connect with Google servers. Tried a multitude of fixes but nothing worked. Ultimately I found that my IMEI and IMEI ID had been hosed and both were now 0's rather than the original IMEI number. I unfortunately did not have the efs partition backed up (at least that I could find). I have tried every method, tool, etc. I have been able to locate to repair or to re-write the IMEI to the phone but so far to no avail.
I restored the original stock software (going back to the original lmy47e on the phone when I purchased it) as well as subsequent releases with a hopeit could somehow restore the IMEI but nothing has worked. I have managed to getto where I can make and receive calls and SMS/MMS but once I'm out of wifi range, no internet access. I even have trid a new SIM from Verizon but tha made no difference. Still a bit confused as to where the IMEI value is stored (and how it could be corrupted) but at this point it looks like new phone time (already ordered a new N6 from Amazon).
Hoping maybe someone might have some suggestion that might help me out. Seems like the N6 is new enough and different enough that the usual fixes don't seem to work. I know discussions around flashing IMEI's isn't really legit on xda but I'm just trying to get back my original IMEI rather than trying to mask a problem phone.
The only accepted way to get it back is to restore a back up. Having the IMEI corrupted happens when roms flash the wrong partitions. Samsung is known for storing the IMEI in a partition that is easily corrupted or erased when flashed. Not normally a nexus issue and I'm not sure which partition the IMEI is stored under.
It is not unheard of that cm roms have some issues like this. It wasn't to long ago that they bricked some nexus.
For the last month my wife has been using her new Tab S2 on WIFI only while vacationing abroad. Yesterday we got home and I inserted her sim into the tablet and she was able to connect via the LTE system and access the internet. This morning suddenly she could not access the internet via LTE. In the ABOUT tab the baseband is blank and the IMEI shows up as null. Nothing was installed nor were any updates received that I can tell. It seems clear that the EFS file is corrupted.
1. The information I have found (none of it from XDA) about repairing the problem all seem to assume a backup of the EFS file, which, of course I don't have.
2. Some require root, which I would prefer not to do, as the tablet is under warranty and don't want to void it.
3. There is an EFS Repair tool online, which is a bat file which tries to created a copy of the EFS file and then to have ODIN rewrite it. The backup phase fails with a message that there is no EFS file to backup. (It's not clear to me how backing up and then restoring a corrupt file would help anyway).
4. There is no access to the phones internal control panel via secret code, or the page that comes up is blank.
5. I tried a factory reset but it did not fix the problem.
Any help out there?
thanks

reflashing did not fix it. The baseband is still unknown and the imei is still null. (I must admit I was wondering where the stock rom was going to get the IMEI from during flashing).
Any other ideas, please?

You may need to send it back to Samsung to get it fixed they will be able to pull a log cat and see what happened.
Hello
I recently lost my s10 and now got my hands on a new one (exact same model)
I thought i was smart and restored a TWRP backup from the lost phone on the new one
I guess the mistake was that there was also the efs partition included in the backup
The rom (newest beyond) works without problems but the sim card is not recognized and baseband and IMEI both show unknown
so i flashed the original samsung firmware with odin but even then i have baseband and IMEI unknown
Did i just screw my new s10 or does anyone have an idea?
any help much appreciated
Anyone has an idea what I could try?
Or did I really kill my phone for good
My guess is that you may have wiped out the new phone specifics, such as IMEI and other things. I'm not sure if you can recover that in some way, or if you need to just find a way to get your old IMEI back. I would probably try to restore my old IMEI if I can (see if you can identify the old one from your carrier's website or something, for example).

I know the original imei, it's printed on the phone but how could i flash that to my phone? Seems to be impossible
There are ways, but they are not allowed to be discussed here on XDA. I've seen Youtube videos that cover it as well.
