Hi guys, I know this is an another post on the same problem, but I follow all trhead on this argument without result.
I have an samsung galaxy s2 whit null emai. I lost it! But I have an old backup of EFS (I thinks it is corrupt because if I restore it, does not change anything )
I tried to restore whitouth success from this backup
I tried factory restore
I tried to recreate the EFS folder whit your two guides
I tried to flash the original firmware from odin whit auto reboot - repartition - F. reset time (I use the file from original firmware but I do not get even a generic imei, it stay null)
I don't know what I can do, and I can't pay 100$ for jtag box only for re enter my own emai
I have another samsung galaxy s2 where the software working (my sister's phone) but has hardware problems. Can I make a full dump of rom and pass it in my phone?
there is a way?
P.S. sorry for my bad english.
updating: I tried to put the EFS folder from my sister's phone to mine but the imei still remains null.
P.S. Sorry for the wrong section
Trying to put the EFS folder from another phone into yours will never work, and changing the IMEI is illegal in most places anyway if you use a particular piece of hardware that mobile repair shops/Samsung authorised repairers use to 'write' the IMEI back to the phone if you bork it.
If you don't have a good EFS backup, it's a service centre job normally, but there are quite a few threads on here which claim to be able to fix it. You might want to look at those; I can see you've obviously tried some things, unless you want to take it in to be repaired, keep trying stuff.
I don't recommend you try to fix this yourself with a JTAG box/similar for two reasons:-
1) You'll be paying for something you'll never use again
2) If you mess it up, it will be a service centre job anyway (or if you slip with the soldering iron, you could damage the phone beyond repair) which you'll pay for plus the cost of the box which you'll never user again.
So take it to someone who knows what they're doing.
No. Trying to copy details from another phone will not fix the problem because the IMEI is a unique hardware identifier which is assigned to the particular radio in your phone.
Same here!
I purchased this phone from a eBay seller and had it shipped to India. Didn't compare IMEI with the one under the battery (stupid, I know) when opening the package, or before flashing to JB firmware. Next thing I know, phone calls are not going and emergency calls only available, even though data network is working fine.
What I did after that (no particular order):
1. Flashed with stock GB, ICS and JB
2. Rooted
3. Tried fixing by steps in http://forum.xda-developers.com/showthread.php?t=1264021&highlight=recovery+IMEI
4. Tried fixing using SGII_Repair
5. Tried fixing using HC-kTool
All failed!
Next option looks like buying a SRS licence and changing IMEI to what is there under the battery. Would this work safely, and restore order to normal in phone? Anyone!! Phone is perfectly new, no signs of use, so assume that I was shipped a proper piece.

No no, I do not want to change imei! I want to put my imei xD and I think this is not illegal, I tried with my sister's efs only for using an clean EFS folder where I can work, I know all EFS are proprietary for each device.
Anyway the soldering are not a problem, but I agree with first point.
I have another question, on GT-I9100 whitouth imei is possible to put the usb in qualcomm mode? i tried with
su -c 'am start -n com.sec.android.app.phoneutil/com.sec.android.app.phoneutil.USBSettings'

but this has generated an error:
Activity class {com.sec.android.app.phoneutil/com.sec.android.app.phoneutil.USBSettings} does not exist

obviously the telephon is rooted and have su permess and busybox
is there another method?
@diffuser911 Unfortunately, I tried the same as you without success :\ Can you enter in qualcomm mode? perhaps you can solve with NV tool (it is in EFS PRO)...I dunno

Can't say I could :silly: I am quite dumb when it comes to android stuff. Which one did you try, SRS server IMEI repair? I have another guy who claims he can fix the phone over the internet for 10 EUR, google for cvxcvx, Polish site.
Have contacted him, awaiting repsonse.:fingers-crossed:

No I didn't try because in the tutorial they refer to phones with a generic imei and mine have empty imei, I would not waste money if the software don't work.
I hope you solve .
I wanted to try the tool of @lyriquidperfection here: http://forum.xda-developers.com/showthread.php?t=1308546
But I have not found a way to get qualcomm mode

That guy isn't too responsive. Asked him to check if system is accessible via the tools he recommended, he wouldn't budge beyond payment. I am thinking of going the SRS Server way.
My phone developed the 'not connected to network' problem which I'm suspecting is down to the IMEI on the software (004999010640000) not matching that on the back of the handset. I've seen the solution in the FAQ but that seems to be for rooted phones. My device is completly stock. Is there an alternative method or do I have to root my phone to get it to function again?

Thanks, that's my weekend sorted.
If you dont have backup of system search for 123unlock download use test user make repair imei in advance option insert your sn and imei and start.pay 25 euros and repair imei.make backup of efs folder for future.2 things, sgs2 must be rooted and on android 2.3.6.
My network provider has agreed to repair the phone if I send them it after a second phone call.
I've bought it like this and i thought it can be repaired, i had a similar problem with my i9500 a while back and i fixed it by flashing some modem on the right firmware, i don't even know what i had done but it took me 3 full days of trying, truly frustrating. I haven't got the phone's imei as it came without a box or accessories hope you can help me out !
Here is what i've tried so far :
- Flashing 3 different 6.0.1 stock firmwares, none of them worked and after every single flash i would encounter device root key error, i have no idea why but it's easily solvable by flashing some kernel as i've seen on some ytb tutorial.
- Backuped the efs folder from phone root on PC then deleting it from the phone root, restart the phone and proceed with replacing the nv_data.bin and the other similar-named file with the ones i backuped then changing permissions to 1001. <--- This i've seen on some forum, i thought it might help, but it didn't change anything!
I really hope you can help me out, i'm bored of searching the web for answers, most of solution i've found are related to some z3x box or octopus and i believe these cost a lot of money and there is no service in my city that can repair phone's imei
Heloo
Hi i had same problem 920f after flash a wrong rom the only fix is octopus box ...they must rewrite imei it cost me 30 euros!
As i said, there is no such service in my city (I live in Braila, since you're romanian too ), but i'm pretty sure it can be solved without special equipment. I think the owner flashed the 6.0 using odin and spooked when saw fake imei then rushed to sell it. It happened the same to me 2 years ago with a i9500 but i eventually solved it without prior backup.
Hey everyone!
I have a Samsung Galaxy S6 Edge G925F that will not connect to a cellular network and wont display my IMEI serial number or SIM Status.
I have tried everything:
Flashing Stock ROM with ODIN (Just get a fail)
Flashing multiple modems and AP's
Backing up and restoring my efs
The phone still boots and I have backups of my supposedly corrupted EFS
This happened after flashing a 5.1.1 rom in ODIN
My stock rom is: G925FXXS4DPIB
Nothing works. Please I need help and I dont have access to a Octopus box to re write my efs either, is there a way I can fix it.
When I put my phone into diagnostic phone with qualcomm's tools I just get a "Device has malfunctioned" error, I'm using Windows 10 64bit

Wow that's the most awful thing that can happen to you.. I had the same problem as you on a MTK device.... I don't know about this device. But I tried with a app that let's you rewrite the IMEI number.. but this didn't worked for me.. maybe it will work for you.. wait some other guys here will respond asap .. also check on YT about your problem. I am sure there you will find what are looking for.

The imei app your talking about only masks the imei number and doesn't permanently change it back to what it was. Thanks for trying to helping though
It's almos a year that I have damaged something and my BlackView BV7000 Pro keep saying "Invalid IMEI" (https://forum.xda-developers.com/android/help/invalid-imei-problem-t3898950).
No app or windows software works, I just managed to restore ONE of the two IMEI, but still having problem with some SIMs.
I finally managed to set my IMEIs, and the way is so simple that I wanna destroy it.
REMEMBER: this guide purpose is sole for restoring your IMEIs due to problems with your phone (like I did formatting all in the memory).
Using a different IMEI is illegal in most countries (if not all countries).
Here you go:
- dial *#*#3646633#*#*
- in Telephony tab scroll down to GPRS option (note: "CDS Information" option doesn't exist in this phone)
- now you can write both your original IMEIs (you found them on the back of the phone or on your phone box)
- reboot
I just find it randomly checking every option. And I used all tools I could find without luck (SP Flash, MTK Tools, IMEI Changer/Restore apps, etc).
Now my problem is fixed.
Enjoy.
Where should I enter the IMEI on GPRS option? thanks for your help man.
