[Help] IMEI lost after 2.3.4 flash !

Hi all,
New owner of a nice Galaxy Ace, i tried yesterday to flash the ROM from stock Froyo to Gingerbread 2.3.4 using Odin 4.38 and SAM dedicated firmware.
All has worked fine... except that when i reboot my phone with SIM card, it is not recognized ! In fact, checking IMEI (*#06#), i have discovered that my phone has lost its IMEI so it can be used anymore for phone services...
I have tried to explore file system (using Root Explorer with root privileges) but i haven't even found /efs folder nor nv_data.bin file on the ACE... Is this normal ? Did i erase the folder when i flashed the ROM (if yes, how ?) ?
Please help me before i send back my phone to my provider...
Regards,
Cedric.

Actually this is one of the things that people are not posting on their update guides, I too am having the same problem. Luckily my phone (which is just 3 days old) is going to be replaced from where I bought it. (I learned my lesson not to mess with my phone) lol! ) Though I hope someone could help with this issue.

Hi,
What is surprizing is the missing /efs folder and imei files on the file system, even .bak ones... and the fact that nobody seems able to explain it or to explain how it should be on the Ace. I wonder if people who have posted flash/root tutorials for the Ace have really proceeded it and if it is not a simple copy/paste from Galaxy S tutorials...
BTW, I brought my Ace this morning to my local provider, it will be sent to repair services. Mine is almost new too (6 days old) so i hope i won't have too many problems with guarantee...

I think most of them probably just copy pasted them tutorials from some other sites and takes credit for em. OH well, people nowadays. I just hope there will be a thorough tutorial/guides that will be posted by veterans/pro's about these stuff. (So we will be well guided).
Thats good, well it hasn't been a week for you. Well my case, it hasn't been 3 days yet thats why they are going to replace the phone.

Hey!
I dont know, what you guys are DONE WRONG! I flashed my phone not less then 30 time(with in 2months) and ALL good. Never LOSE MY IMEI.
Really cant help. I think you done something WRONG(not FOLLOW the INSTRUCTIONS step by step or something else). Its my opinion!
CHEERS!

Dont happen to u doesnt mean it wont happen to anyone else. Btw im also flashed my ace more than 10 times already, and never encounter lost imei problem. But reading this made me realize how critical this matter is. I know that imei on android supposedly were stored in efs folder, but on my ace i couldnt find that folder to backup. Weird...
So anyone can clarify this? Is it true that ace doesnt have efs folder? And if its indeed doesnt have that folder, where does our imei were stored instead?

That's a very good question ! Maybe if i had known where imei is stored, i would be able to restore it myself instead of send my phone back to support centre and
take the risk to pay cash for the repairing...

Don't judge the people from this forum, i have flashed as well with odin plenty of times, and encountered no problem. Flashing really takes risk, we may have similar phones but the situation in which we upgrade them sometimes is the key to the outcome, like what operating system you used, open line or operator locked phones, corrupted files, etc.
By far you were the first i saw that lost their IMEI after flashing. I'm not saying it would not happen again to others, this may be a bug on the upgrade process, but such rarity might be difficult to investigate, but taking the risk is part of the game, don't blame other's if you have failed.
Goodluck on your repair, and hope you have a successful upgrade next time.

I flash my ace couple times. Still have my IMEI.
But want to backup my IMEI, i cant find /efs folder on my ace.
Does anyone, have /efs folder on your ace ?

Don't touch EFS on Galaxy Ace. Especially do not make a dump (dd) of it.

Ok but why ?... I agree with the fact i have encountered a special case which doesn't affect other people, but i won't do any further flash of my Ace without understanding what has happened.
I have strictly followed the tutorial step by step, using Odin and a multi-package KPE ROM from SAM firmware... i am not the first one who lose his imei on the Ace after a flash, i have found several similar cases on forums. Very strange...
Above all, how are managed EFS files on the ACE ? That's the question, and until now nobody knows or wants to tell it : weird isn't ? If i had known this, maybe i would have been able to restore IMEI myself, it's a very important point.

But i cant found any /efs folder on ace.
Is there a way to backup IMEI ?

Have you by chance tried to unlock the phone with the Galaxy Ace Unlock app available on the market ?

IMEI is readed from HARDWARE, not from SOFTWARE(SOME FOLDER OR FROM SOME FILE). If it was in folder or somewhere in FILE, then we can change our IMEI.
Its not SOFTWARE base number. Its HARDWARE BASED NUMBER.
YOU CANT CHANGE IT. You must change your hardware, to change your IMEI.
And back to problem: I think that software CANT read your hardware RIGHT or its not SHOWING to you your IMEI(somehow its the software problem).
If you flashing, FIRST be sure that you CLEAR CACHE AND RESET System settings(IF YOU WANT TO BE SURE THAT NOTHING CANT MESS YOU PHONE SOFT).
Maybe this can help too: REMOVE your SIM and SD, before you flashing your phone!

Not true. All that info is stored on an unmounted efs partition. Don't try to read, mount or dd that partition, as it's highly probable that it will get corrupted. Don't use unlocking app either.

OK!
Maybe you can read your IMEI from SOMEWHERE IN FOLDER OR....., but IMEI is read from HARDWARE, its not SOFTWARE BASE. If you want to change your IMEI(like SELL to other ppl phone, then you can sell it, but you CANT change your IMEI).If you phone get DAMAGED and you bring it back to SERVICE(they can change your MOTHERBOARD, LIKE IN PC AND YOU GET almost new phone. But IMEI is changed and your HARDWARE IS CHANGED TOO).
I know this by my self.
IMEI is NOT software NUMBER!
If you not belive it, use GOOGLE to search, before ANSWERING! READ THIS

Hey!
Agree with you, but IMEI never WAS and NEVER BE software based number man. Still, just use google to find out. Like I sayed, if we all know where is IMEI code, we can CHANGE IT. But we CANT(IF YOU NOT CHANGE YOUR HARDWARE).
If you dont know, DONT link to our forum(I can use the SEARCH button[LOL]). USE INTERNET, like google!
I see, you dont READ my links!

I think there is hope for you guys. I once had the same problem with my sgs2 and I searched everywhere... Until I found someone that send me a efs tar file... I told the guy it wouldn't work cause I tried everything... And I had to flash it with odin in the pda section... It totally solved the problem! I don't know where I found that guy but if you just search the net a bit longer, yoi could find it. Just search for efs tar file. It gives you another imei number so be carefull... It's forbidden in some countries...but yeah...
I also found some answers if I typed "baseband unknown galaxy note" in google. About somesort of tool...
Good luck!

Please, can I contact with you? I really need those files for fixing my phone...

You're original imei is specific to the phone and registered with Samsung and the network. If it's corrupted and you have no backup, there is no one who can restore it except samsung. You can create a new imei, but it's illegal and of no use at all. Don't get ripped off by people claiming they can restore your original imei, it's just not possible.

Have you tried flashing a 3 file gb firmware in odin? That always worked for me in the sgs1 days, if it does work get that efs folder backed up immediately

Read the post before yours. It's not possible to do it because of the unique IMEI. If you do not have your old one (written on a sticker inside your device) then there will be not solution.

Phone does not connect to Network (started after being stuck at samsung logo)

Hi everyone,
I rooted my note and was using Jon ROM V3 for the last 3 months. Never had any malicious apps and my phone was working as usual.
Yesterday I took my phone and see that it is stuck at Samsung logo (an hour ago it was working fine). Tried reset and re-flashed ROM but no luck.
Later through download mode i flashed Official Indian Firmware(I live in India). Now I by passed the logo screen and the phone shows full signal bars but not able to connect to carrier network.
(tried all basic work out like removing battery/sim and re-inserting to phone and boot up)
I pressed power key and it did not show the power menu , it directly switched off mobile.
I rooted again with Philz kernel and flashed JON ROM. Still i see that my phone is not able to connect to any network. Also I observe that even here on this ROM when i press power key it directly turns off.
This is weird. I thought my IMEI was wiped off but im lucky to see that its still there.
I need your help. Im without my phone for the last 2 days now.
-
Jonathan

Note - I find that my IMEI number has been changed (to some generic IMEI 004999010640000) after i flashed the official firmware !!!! that's why it is not connecting to any network.
Someone please help me.

How did you flash the official firmware?
was it a tar file or a zip? I mean did you use odin?

It was a tar file The official Indian firmware I got from sammobile

either a glitch or you selected by accident clear efs.
anyways without efs backup hard to recover emei.
Do you get the simcard enter pinscreen on boot? If you dont then its not imei, if you do then you need someone like cvxcvx, search to fix it. That or Samsung

No I do not enter pin for simcard. I see my imei has been changed to 004999010640000. I tired fixing one problem and got onto another.
I guess there is no way other than sending my device to Samsung !

You have a so called "developer IMEI". If you didn't safe your EFS then there is no real chance to restore it yourself.
There is a member (cxlcxl) who has hardware and can restore the original IMEI remotely.
But you still can use your device. Try to change the Sim Pin in the settings: you can use the same Pin for old and new (this is easier for me because sometimes I forget the new number).
After this the network connection should come back.
My workaround in my Pristine Custom Rom: one different jar-file that doesn't have the checks on startup from my old XXLSC dump. With this it works completely normal: Sim and Pin are always recognized from startup. I'm using this for many months now.

[Solved] Backup ModemFS (GT-I8190L)

Hi,
I recently got a mini s3 (i8190L) and, of course, loved the smartphone.
I did root the device, installed CWM and installed a Custom ROM compatible with my version, the Dmod v5.
My device does not recognize the baseband, it says "CP" and "CSC", despite the IMEI apparently be ok.
Baseband: XXXX
AP: I8190LUAMB1
CP: XXXX
CSC: I8190LZTOAMA1
Biuld Number: JZO54K.I8190LUBAMB1
Restored the default firmware (HOME_I8190LUBAMB1_I8190LZTOAMA1.tar.md5) several times between tests and nothing working.
I've tried sooo about it and keep looking, but this hard to find a solution.
Problem: I can not get on the 3G network and not use the internet service provider (Claro - Brazil).
Can anyone help me? Perhaps a simple backup who has the same device solves. Please, I'm desperate.
#EDIT------
Someone who has the I8190L, please put backup your modem.bin?
dd if =/dev/block/mmcblk0p12 of=/storage/extSdCard/modemfs.img

Hey,
search on xda ("baseband xxxx") , the answer is already out there
you need to reflash your modem and efs !
=> you will need root (including terminal) & the two backup img
then you will need to flash these

When I open the "CSC", it gives me no option to change.
I have root on the device, select the option and the option open, but still.
I tried to use the ROM Benz in v2 (which seemed to be a solution), but then started to not catch network and recognize the SIM out instead of giving "XXXX" in number, came to be "unknown".
Someone who has the GT-i8190L of Brazil, can, PLEASE backup the EFS for me?
Is there any other solution besides the backup?
#EDIT------
The problem is that I am new to Samsung and time to wipe I formatted the modem, this was my mistake.
Would like very much that someone postasse backup for me, ^ ^.

In the first post, the user asks to post only the i8190 and not the "L" or "N".
If I play these files on my machine, I run the risk of losing it or I risk it?

But in EFS the IMEI is stored or not ?

Enox AMD3 Revenge is not only for the GT-I8190?
#EDIT---------
Before doing all this ****, I did the CWM backup, but even giving wipe everything and restoring it, still not working.
The problem is more severe or the CWM backup does not back up the Modem / EFS?

I'm saying that I use the one from ENOX revenge Rom thread. But I don't know if you are looking for that file...

I do not know if backed up with CWM and copy the folder EFS ModemFS, but I'll wipe around the cell, restore the backup and backup again, but only the EFS and ModemFS.
If that does not work out, try to Enox. ^ ^
An hour has to go right, lol.

Friend, try no to screw your EFS partition..it contains the sim-lock infos and the IMEI as well as another sim-related settings, try to flash that modem, but DO NOT try with EFS.. it isn't the first time I see someone crying because they screwed their EFS partition and losing the sim-unlock.

Thanks for the warning.
Because, everything works normal, be called, sms, wifi, bluetooth, etc.. Only what does not work is the internet's operator, because when I'm in phone status, it says "Unknown" in "Mobile network type" and does not recognize the "Status" it.
Anyway, still in search of a possible solution or the backup (if I can) solve the problem.

Restored the default firmware (HOME_I8190LUBAMB1_I8190LZTOAMA1.tar.md5) several times between tests and nothing working.
I've tried sooo about it and keep looking, but this hard to find a solution.
Problem: I can not get on the 3G network and not use the internet service provider (Claro - Brazil).

Is your phone locked to Claro? If it is, then you're flashing the wrong FW.

You need a file named NV.DAT, it's missing from your /modemfs/PERM/PROT
Use this one.

He is unlocked by default here in Brazil, but even so, I've tried the Claro, Tim and Hi, besides the Clean ROM, but none of them worked. : (

[Q][GT-I9305] EFS, IMEI Repair

Okay everybody,
I decided to write a new thread for my problem because I think my prob is a very special thing.
I'm from germany, so please don't wonder about my english. I think it is a understandable.
The story begins with a software update for my GT-I9305. After the update, the IMEI was just "null", after some work with google I found out that the efs partition was broken. With my bad knowledge for this case, I destroyed the whole EFS folder. I installed perseus kernel. And, there it was! The whole and correct IMEI. The solution was the perseus kernel (stock doesn't work, neither reflash). But then, after a while the phone doesn't boot anymore. I flashed Android 4.4.4 and my phone was revived but the IMEI was again "null". I have no backup or anything else!
So I spent approximately 20 hours or more to understand the efs thing. I found much solutions but nothing worked for me. So, here I am.
What I've tried before
-reflash KitKat
-reflash Perseus (not compatible anymore)
-formatting efs partition for a blank and new EFS for editing
-tried to edit nv_data.bin with HEX
-tried to backup efs with a 3rd party app and edit this with hex (the app doesn't support my GT-I9305)
and then, there it was:
-tried to use a working EFS partition from another GT-I9305
-editing with Qualcomm NV Tools! (I think THIS is the solution!)
I tried NV-items_reader_writer (1.0) and EFS Professional (2.1.73), but in both can't find my phone:
What I've done in NV-items_reader_writer
-dialed *#7284#
-at "Qualcomm USB Settings": "RNDIS + DM + MODEM"
-enabled USB Debugging in phone
-connected the phone
-opened NV-items_reader_writer
-checked the both boxes near the SPC box
-selected the right port (last: COM4)
-clicked on "connect"
-clicked on "read"
-> here it search the phone, but it can't find it and says "Failed.. Phone does not answer"
What I've done in EFS Professional
-dialed *#7284#
-at "Qualcomm USB Settings": "RNDIS + DM + MODEM"
-enabled USB Debugging in phone
-connected the phone
-opened EFS Pro
-clicked on "Qualcomm NV Tools"
-refreshed the Available COM Ports
-selected "SAMSUNG Mobile USB Serial Port" (last COM4)
-clicked on "Connect"
-> Here it takes few seconds and he stops and says: "Phone connection has been lost!" and "Unable to send SPC to the Phone!"
What I've tried to solve this problem
-tried QUALCOMM USB Settings: "DM + MODEM + ADB"
-reinstall all Samsung drivers
-tried to install Samsung Modem with Qualcomm drivers (failed due to wrong platform; I've Win7 X64)
-reinstall Samsung Kies (for actual drivers)
-tried to dial *#9090# (in my case, this menu is totaly blank)
-tried in factory mode
It could be that I forgot some....
Now, my question to you all is, do you know what I've done wrong? I mean, this is working for the most users, but why not for me? What do you think? Did you think I really forgot something?
Some informations:
Phone: GT-I9305
Android: 4.4.4 KitKat
Kernel: Stock (3.0.31-2760029 ; [email protected] #1 ; Fri Sep 12 13:08:24 KST 2014)
Buildnumber: KTU84P.I9305XXUFNI3
Windows: Windows 7 X64
Do you need more informations? Post it!
Please help me, I want to bring this phone back to life!
And yes I know, to change the IMEI to a number which is not your own is ILLEGAL and to prevent this, it is not well seen to talk about, but this is MY PHONE and I want to change the "null" IMEI and IMSI to MY ORIGINAL IMEI. If this is a problem, I can send a PM to an mod with my phone (where you can see the IMEI), my username on a sheet of paper and the original box with the IMEI printed on. All on one picture!
Simply... I need a hero! Be MY HERO!

im in the exact same problem as you. the reason nv tools and efs reader is not seeing your phone is because you have NULL well usb wont work. so try installing the original 4.1.1 firmware, then install perseus, then nv tools and efs software will see your phone. if you end up fixing it please help me out. upgrading to a later firmware is where I get stuck. just stays on the boot logo. and like you said perseus isn't compatible. you seem to know how to use nv tools so hopefully you can get somewhere. as I don't no how to use it. GOOD LUCK.

take your phone to the samsung if you have warranty.otherwise give to a phone repair shop for repair because your problem can only be solved with special boxes and equipments etc, and they have it. it will not cost too much.

I tried this, already. But I can't downgrade from 4.4.4. I don't read very much about this. I just know that this is a new security option from samsung (or Android)... I will tell you when I know more

The warranty is already expired...
This will be the last step I will do. Before this, I will try my very best to do this at home... But thank you for this tip
Edit:
What do you all think about this idea:
-I try to find somebody with a working EFS on GT-I9305 Android 4.4.4
-I get a backup from him
-I restore this backup to my phone
-I edit the duplicated IMEI with NV Tool to my IMEI
This requires that the NV Tool will with work with an existing IMEI and the the phone will be THE WHOLE TIME IN PLANE MODE to prevent IMEI ban...
What do you think? Will this work? Do I need somebody from germany (DBT) or is this not needed?

Take it to a phone repair shop they might have a way to fix it. And if they don't they might know someone who can and it would likely be cheaper than Samsung service center

Thank you, I will try this, too. But this is more if your efs isn't mounted. My partition is there but just clear.
I will tell my experience after testing.

Now I tried my idea with the EFS partition from somebody with a working GT-I9305. In my case, this isn't working... I think I must try the next step and try to repair it from a shop or so...

Hello,
someone could give me an EFS file because I deleted mine but my camera would not boot and remains on bootloop
thank you in advance

Repair shops aren't as expensive as you think to get my camera replaced all up cost 50$ au dollars and when I first got into Android I trashed heaps of phone's (low end thankfully) before I knew what the hell I was doing and never cost me more than 80$

I want to update all you guys.
I flashed the old bootloader so I was able to downgrade to Jelly Bean. There I installed perseus and now I could connect to the Network, but I don't want. IMEI ist still 0.
But now I can enter *#9090# menu. But I can still not connect the phone with any DM Prog

If you were to 4.4.4 Official Stock rom can`t do downgrade the bootloader.What you have done is downgrade to Firmware with extracted knox bootloader.But you still with EFS corrupt partition.

Hm okay. I applied a "old bootloader" before here from xda. I don't know what it was exactly. There was a boot.so or so in it.
I will try my best. I mean, if I can beat this, this is a really great success for me. My next step is to restore a full NAND backup from a friends of mine (from a GT-I9305).
I wondered about that, after I restored a working EFS, there were no NV data.

Hi guys, i had the same issue: after a botched restore of nandroid backup (something to do with it being over 2GB, different story though), I lost IMEI (null/null) and no baseband.
I was running CM so I tried to flash the original Samsung ROM, to no avail. Then a whole bunch of other stuff that didn't work, until:
- I flashed kitkat (which failed due to some error in the install script, dunno why)
- then flashed my last nandroid, which I had already flashed with no restoration of phone functionality, HOWEVER,
- I then flashed over that nandroid the modem files (see here: dropbox.com/sh/d2ljv1ylvr9nvib/M7UzMgux4f) , mine was Modem-I9305-XXUENE2.zip for i9305 LTE Intl.
- tadaa! fixed
hope this helkps anyone, took me some 20 hours of tinkering

aside from the dropbox link in my post above I did not use much else. I downloaded a stock kitkat rom, but don't know from where.
