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!

Dear all,
My moto x' IMEI got invalid after having a repair process. May I flash the raw valid imei to the device ?
You know I have my own valid IMEI number
If a repair shop messed it up, they should fix it.
You can try flashing your devices exact firmware... Same Android version and see if it fixes it.
Other than that, any talk of manually manipulating your imei is mostly illegal and definitely not discussed on XDA. ?

No hardware "repair" will just result in you to loose your IMEI it would have screwed up more! And if its a result of a software "repair" it is almost cuz of mismatched partitions, so flashing the whole firmware for your device should help to correct the issue!! If the repair guy has the "tools/power" to mess up your IMEI he should definitely have the ability to restore it back... Other than that changing IMEIs is ILLEGAL is almost ALL COUNTRIES and against XDA Rules!

IMEI is generic to the Mother board it is pre programmed into it... So if you have lost the IMEI that means the repair guy gave you a faulty motherboard... You should catch hold of him... U dont have signal right?

The xt925 was the last moto you could mod the imei on.
hi all, i have my phone repaired by non certified technicians, because i have a bootloop for my phone. when i unlock my BL it shows different imei than what shown in my box. if someone flash different TA partition, should their phone bricked? because my phone was not bricked, it was just bootlooping, after passing loading screen, it was black screen, than, it was restarted.

They swapped the motherboard for sure. You cannot change imei via software, its impossible, its encrypted. And any attempt to ask here how to change the imei will be banned.
If you need to proof the technicians that they changed the motherboard, you make them compare the imei that appears on the bottom of the phone with the one that comes up when you dial *#06#.
Good luck.

You need someone's modem EFS/QCN backup file. They need to have the exact same version phone you have

Lol didn't think of that!
Perhaps the person can alter their file and remove their IMEI number or make it all 9s.
He can open the file and edit it with his real IMEI (assuming he has his box or the real number written somewhere)

but see that's the thing, I'm pretty sure he doesn't have it. If he did it would be simple to edit the ftm partition, which has worked for others. But there's really nothing u can do if u don't have it.

That absolutely makes sense!
When shopping for mine, I noticed some of these V40s have their IMEI #s printed on the back.
Would be very silly (and lucky) if the O.P lucked out, had an IMEI printed on the bottom and overlooked it.
Otherwise, I'm wondering if he can somehow talk with someone at his phone provider tech support and see if they can share the number of the last phone that connected to their service.
Pretty sure if he catches the right person, they may share his V40's IMEI after he successfully identifies himself

I had this problem back in the LG G2 days, had trouble with my EFS too but was able to recover. Sounds like something is off and is not coming through from your EFS backup.
If you search my screen name you'll find an old thread I made about it from years ago. Hopefully the steps will be similar and can be helpful to you.
