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!

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.

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!

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.

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.
Have any of you restored a Captivate's EFS folder with another phones file to fix network/IMEI problems? if so did it work?
I don't have a backup of the EFS folder (didn't know it even existed), did a factory reset (after a couple of months of having the stock 2.3.5 flashed) and suddenly I can't connect to my network provider (no phone calls/txt/3g).
I read different forums stating that I need to restore the nv_data.bin file to get the product code back (it's mostly ceros product code on 0188008 Not Active) and my IMEI is also screwed up.
I changed the product code and it apparently stayed changed, but the entirety of the file seems corrupt comparing to the videos of how to modify it and IMEI is still the fake one.
I would appreciate if I could get a backup of the EFS folder to modify to my phone if at all possible (I'm NOT on ATT nor in the US for that matter) sending it back for repairs is sadly not an option.
Trying to modify an existing file seems like my last shot to fixing my phone =( please help =D
U are out of luck, nvdata from other phones will not repair it there are only 2 option's
1. If u can find someone who can repair the NV_DATA.BIN
2. You can find a repair guy with the Z3X box.
Edit- OP if u want a fresh NV_DATA file just PM me ur email address i can mail u a copy.
I'm assuming you've tried the steps in this post?
Even if you don't have a functional EFS folder, just follow the steps as if you did. It might be worth a shot.
@jmtheiss I have question regarding the above procedure..
I tried the above with a corrupted nv file but the step mentioned in the thread aren't they are just for the product code ?
00188008|2e|34|00|00|00|00|ff|41|.4....A
00188010|54|54|00|00|00|00|53|47|TT....SG
00188018|48|2d|49|38|39|37|5a|4b|H-I897ZK
00188020|41|41|54|54|00|00|00|00|AATT....
If I'm reading the thread correctly, rebuilding the nv_data.bin file with the proper values should repopulate the /efs folder with the correct and necessary files.
It's possible this may run into a hiccup because you're not connecting to AT&T, but in theory, it should fix your problem.
Also, it appears that other people had good results by flashing to stock first, then trying this. It looks like the stock flash reset the IMEI, and then doing this fixed the product code issue.
Thanks for replying,
I treid every thing that i was able to find to repair the NV_DATA but apart from some links to XDA there is not enough knowledge how to repair it.
I tried every possible method to repair the imei, i have more the 25 backups of different NV_DATA files with me and over the time i had looked it to every possible file and treid to compare them with each other and they all look the same to me if we look into them with the help of a HEX editor.
I tried to change the files with 2 different phones and changing them with will give u imei code >004999010640000 but u cannot not repair it with anything.
I treid this with the phone with 2.1 update 1, 2.2 and 2.3.3 but what ever they will not work.
But after some research i found that the most of the guys who repairs the imei they use the Z3X/SPT for it and that is how i did it and its was recently some 6 days back.
I am still trying to find out how (if) you can manually repair the corrupted NV ?
You can contact connexion2005 in my sig. He does IMEI repairs for a fee. But it is worth it. he is a good person and doesn't cheat people out of money!
EDIT- Don't ask people for their EFS folders.... That is sorta really stupid.

I'm a recent customer and I was very pleased with his service. 1 week total and everything is back to normal. I have backed up this new EFS to MULTIPLE places.
sorry for the no reply, I contacted conexion, waiting for his reply.
I know asking for the efs folder is not bright, but it was my only and last shot. I triead all other threads and was able to change it to what they mention, add product code and everything magically gets fixed... but it saved the product code and the file and imei stayed pretty much the same, so I'm guessing that doesn't work =(
thanks for your replies all! appreciate the support

Use Odin or Heimdall to flash to Stock KK4 Gingerbread. That has proven to restore imei #'s for some.

I have this problem but unlike the majority, I have a working phone (i.e. I can make phone calls. WiFi, Bluetooth, and GPS are all working fine.) so I think my EFS is not corrupted. I've come across a certain ariza patch but unfortunately, it's for I9300 only. Is this the only cause and restoring from backup the only solution?

Sometimes restoring EFS wont work, and you still end up with zeros as your serial number.
Contact ariza, as i understand his fix is a patched modem. maybe he can do that fix for i9305 also.
And definitely it works.

Why one give own EFS backup to use on other device which is illegal?
Every device have it's own EFS and using multiple copies, network soon ban both the devices. I request everyone to read before sharing. Other than this this is development forum.

Thank you verymuch Dr Ketan
AFAIK , restoring the EFS backup of alone will not give me the network ( IMEI certificate PASS is mandatory to get network )
I just want to confirm the issue with the Baseband., whether chip is OK or not.
Certificate patching is currently not available for this device.
If anyone interested to help , Please share.
