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!

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!

CHEERS!
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.

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

Hello partner!
I had the same problem with imei after years of using various roons.
In my case I had a rom lollipop, between a night and other My IMEI is gone. Follow almost the same steps you. After a long time searching the internet was found a case was solved by installing an original rom Samsung via Odin.
Just wiped everything on the recovery and follow this tutorial and today I am with my IMEI back, and well relieved.
I hope it helps you too.

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.
after installing the baseband.img and radio.img from this thread:
[ROM] [Stock-Debloated][6.0.1][MMB29K][08/12/15][Layers]Rooted-Deoxeded-Fast & Stable
i am receiving a 'no sim' message when setting up a new rom. if i do a restore from a backup, it loads up fine, but i get the slash through the 4g bars in the notification area and under 'about phone' it shows 'unknown' baseband info.
any comments or helpful suggestions?

I'm having a similar problem (i.e. no sim but I did not install the radio you linked to) but I had a backup of my efs partition as part of my nandroid. I tried restoring everything (including efs) and still have a no sim. I've tried other sim cards and the same thing. I also tried putting some tape on the back of the sim slot to tighten it up to ensure that contact is being made but that didn't help either.
Any help would be appreciated.
Thanks.

that is the only way i had ever flashed bootloaders or radios up until this time. this time i used the NRT to push the bootloader and radio *.img files over to it and a corruption resulted (not blaming the files or wugfresh's tool.. i think this was a freak occurrence....).

I also tried putting some tape on the back of the sim slot to tighten it up to ensure that contact is being made but that didn't help either.
Any help would be appreciated.
Thanks.

i don't believe i can help you much. i already ordered a replacement phone and might try to send this one back to motorola. perhaps it can be fixed for a small repair fee?

that is the only way i had ever flashed bootloaders or radios up until this time. this time i used the NRT to push the bootloader and radio *.img files over to it and a corruption resulted (not blaming the files or wugfresh's tool.. i think this was a freak occurrence....).

Why don't you download the full stock image from Google, extract the radio and flash it with fastboot? Nothing to loose i guess.

way ahead of ya.. already reflashed the google image on it and relocked the bootloader. still says 'unknown' under the imei and 'no sim' in the notification panel.
thanks for the suggestions though... would be nice to get 'er working again as something other than a tablet

under 'about phone' i see Baseband version 'unknown'.
under 'status' for IMEI information it shows unknown for imei and imei sv.
pretty weird, huh?

ok, then it's indeed your efs partition.

speaking of which, i see a lot of folks saying that twrp backs this up.... i made a backup before i made my changes, but there was no /efs to be found.... any clue where this is?

if you don't check/enable the option 'efs' just before backup starts....
I backed up my efs, then restored it and still have this problem. Thoughts?

Did you back it up before your issues?

Yes. I have multiple EFS backups prior to the issue and restoring them doesn't help. I still have a no sim card message.
Thanks in advance for any help.

I was able to solve my problem. Although I had a backup of my efs partition restoring wasn't helping. This time I mounted system and firmware (both were unchecked when I entered the mount settings in twrp) then restored efs. This time it worked and I got my imei/basband back.
I just thought I would let others know just in case it could help.
Thanks.

Wow, one of the very little people that also let others know that a problem is solved and how it is solved! thank you!
thanks for the info, this seems to be the exact issue my device was having, i'm just going to return mine since it's new and i never unlocked the bootloader or anything (device was like this out of the box) at least now i know i probably couldn't fix it since it never worked so i have no backups from a working state.

after installing the baseband.img and radio.img from this thread:
[ROM] [Stock-Debloated][6.0.1][MMB29K][08/12/15][Layers]Rooted-Deoxeded-Fast & Stable
i am receiving a 'no sim' message when setting up a new rom. if i do a restore from a backup, it loads up fine, but i get the slash through the 4g bars in the notification area and under 'about phone' it shows 'unknown' baseband info.
any comments or helpful suggestions?

I have wiped my efs file and cannot make calls or receive emails. can someone let me have a copy of the efs folder for the above. thanks SM-N950F
If they did that your phone would be using their phone's IMEI, as that is stored in the EFS partition.
Instead, I would recommend searching for a repair guide as I have run across those, and they will help you fix your own EFS and restore the phone's true IMEI so there's no funny business going on. I can use my Google-Fu skills for you after work if you are not able to find what you need on your own.

I have sorted it . the problem was connected to wrong csc file . I'm on o2 I flashed csc for t mobile. thanks
So I did a stupid and flashed over a single-sim N9600's EFS partition with a dual-sim N9600's, and now the single-sim one won't accept any SIM cards with an invalid/network locked SIM error. I've tried just about everything besides zeroing the EFS (because I don't know how to to that) and so all I can do now is ask all of you beautiful people if anyone could share a TWRP EFS backup from a single-sim N9600 to (hopefully) save mine.
My apologies for being dumb, and thanks in advance everyone.

I'm not so sure you can use EFS from one other phone, but if it works then, what consequences might have the owner of the original phone if there is in question security breach?!

I'm not 100% sure myself, but some if the Snapdragon devs said it might be able to rescue it. As for security concerns, what sort of security breaches would you be referring to?

EFS is my phone identify, imei and serial number is in it, if happen to do something illegally over internet, social-media, money laundering or any other crazy things, justice might or will hold me accountable, and is not good idea for me to share that.
But, i think is better for you to check about how to resolve EFS problem, there is e developer who posted one article about to rescue or generate and solve this problem, so check about note edge or note4 as much as i remember.

Fair enough. What's odd is that the IMEI still matches the phone itself. When I didn't know what I was doing and overwrote the EFS partition with the backup TWRP did say the restore failed, and was unable to write, but the devs said seeing that was normal. Could the problem be the modem partition instead, or something?
I saw the Note 4/etc threads about zeroing EFS, but since they're quite old I wasn't sure if those instructions still applied to newer devices and if they would break things further than they already are. Should I make another thread asking about that for contemporary devices or would those old instructions still be okay?
