After going through various threads in XDA, I have come to one big conclusion. There is no way we can restore IMEI on Ace since we cannot mount efs partition. I wish I'd be wrong. This problem is only fixable at Service Centre's

So basically I have a phone (not mine) that says Baseband version: unknown, no IMEI when dialing *#06# and doesn't recognize SIM card at all.
Apparently the phone is running stock KK9 2.3.6. AFAIK it has not been rooted or had custom ROM's installed.
The owner said it recently started dropping from network, and usually didn't reconnect at all. This would indicate a broken baseband chip, since now it doesn't even recognize the card?
Any suggestions what to try?

EFS corrupted? Any backup done?
No backup done.

Apparently there is a backup of the original EFS file - is it possible to just restore it?
do u meant the original files under /efs/? If that's what you meant, try to follow the steps in the previous SGS2 link. Else if it's an external EFS backup image, then there should be no problem restoring it ie. with EFSProBackup. good luck...
Now it's getting even stranger;
the phone works fine when the battery is removed for about half an hour and SIM card installed after that. I left the phone on my desk without the battery for the night, and now it works just fine. But I know that when I reboot it, it loses the baseband once again.
You mentioned you've flashed a stock rom before, which method did you use, pc odin or cwm/mobile odin? did u do a full wipe?
After restoring ur EFS, do a nand backup if you need to then wipe data/dalvik/cache from recovery mode and reflash via pc odin with a stock rom in ur region...
It look like to me you are having hardware problem. Send it back for replace or repairing..

i just flash custom rom ChobitsDigitalisV1_ROM and finished but getting error imei and phone modem unknown..
Corrupted /efs folder. If flashing to stock ROM didn't help, then it's over, you're stuck with no GSM, and possibly all other wireless features (GPS, Bluetooth, WiFi)
Sorry to hear that, but next time flash ROMs that are tested by other people and are reported to have no problems. Yes, it can happen with every flash at any given time when you don't expect it, but I'd rather go for tested "safe" ROMs. Unfortunately, for those who are scared, I can't seem to find a way of backing up the /efs folder on Galaxy Mini!
Anyway to backup efs without the use of pc.

Did you droppe dyour device? I dropped once and my phone can't read my sim card. No pin needed after boot and can't call. Bring it to repaire. I guess it is the hardware problem
Hi everyone,
Hope you can help me solve this, cuz I'm way out of my knowledge..
My phone broke the lcd and was out of action for a few months.. After I finally got a replacement screen, the phone wasn't working and said IMEI unknown, I've tried to flash a few roms via recovery but nothing. So I just went crazy and flashed it via kies. It worked, the imei appeared but the phone was locked again..
Back to the shelf a few weeks until I could afford to pay for unlock.. When I picked it up, it was unknown IMEI again and the guy at the shop basically told me he couldn't help.
Was he right? I refuse to believe I can't recover the phone.. Can you please help?
Thanks!
Anyone?
Are you sure is that phone imei is not blocked, because provider may block if it is stolen reported.
I had the same problem after changing display IMEI unknown
But somehow it was saved from 'unknown IMEI' I don't know how.
restored efs from previous backup (twrp & philz recovery)
- no imei
I flashed stock
- no IMEI
asop
- no imei
tried different modems
again stock
- suddenly its worked
(some users reported flashing different modems worked for them)
Yes I'm sure imei is not blocked by network. Have a friend that bought a phone which he discovered the hard way it was stolen, anyway, blocked imei by network behavior is completely different.
This is what happened to me first time only valid imei after kies rom update.

If you see imei again, Make a backup using pc, there is a guide in development section. So, you can easily restore again.
HELLO EVERYONE.
i have a samsung i9305T i flashed it wth L.P rom then suddenly
my imei went 0049. i tried anything bUt no luck. so i decided to flash a stock one
4.1.2 my imei was back. But when i try to insert my network sim it says.
NOT REGISTERED ON NETWORK . tho ived used this phone before here in the philippines
so im sure it is unlocked.
any help guys.? thank you in advance does my baseband caused the issue?
please help ...
Hi,
I'm not an expert at all but i have a theory :
I think you get a corrupted EFS. You flashed L.P rom so the format of your EFS changed to V2. So when you tried to return to 4.1.2, the phone can't read your efs anymore.
I think the solution is to flash a newer baseband, for example the L.P baseband or a KK baseband.
Read more about efs format => http://forum.xda-developers.com/galaxy-s3/general/ref-imei-efs-stuff-i9300-including-t2393289
Hope it helps.
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.
