Please HELP!!!

Hi guys,
I hope you pleeeease can help me I am desperate. Turns out today I Got a new N7100 because my old one was broken so the guarantee gave me a new one. When I returned home, i made a restore backup from my old phone into the new one and by muistake (stupid stupid mistake) I didn´t backup mi EFS folder, so now the phone is not working and giving me a generic IMEI....
Please tell me that there is a way to fix it without the EFS backup... I am just about to cry here
Thanks and sorry my bad english!

Try flashing a stock rom via odin. If that doesn't fix it you're screwed I'm afraid.

I always make backups of my EFS but I don't know exactly what it is for and how they work. If someone gives you a backup of their EFS will it work or is it related to the machine?

Well, I guess you need to flash back original Sammy ROM and bring it back to Samsung, no other choice. Sorry

Like above flash back your original stock rom. Pretty sure this is the only way.

Maybe this thread can help you..i think the OP of that thread face same problem like u did..lose imei no..

[Q] efs problem after flashing ROM

Hi,(I asked a similar question on the hawkish rom thread. But maybe someone here knows a solution)
I flashed hawkish rom, and made a nandroid backup, and backed up all my apps, but not the EFS partition.
After flashing, I can't see my network operator. I'm in germany, and I see
o2 - de, E-Plus, Vodafone.de, but I can't see telekom.de. Instead, the first line of the operators is empty - has no name.
*#06# showed as IMEI 0049999....
After much fussing with the EFS directory, I managed to get to a state where my IMEI shows up correctly with *#06#.
I also tried flashing various modems, but nothing helped.
When I click on the empty line among the operators, the phone does evenually register to that network, but nothing changes -still emergency only.
"About device" shows in Status: Network Telekom.de, signal strength -101dBm 5asu, Service state "Out of service"
What could be wrong? How can I fix things?
Thanks!!

Turns out I have an efs backup
It seems I do have a backup of the efs folder as a tar.
What is the best way to restore it?
I tried mounting as r/w and just overwrite the folder, but that didn't seem to change anything - I still can't see the network operator
(the imei is correct, though...)
So, what's a good way to restore the efs?

Thats what I asked you as if you have flashed the latest dmg1 modem as that would have solve your prob as on first post u mentioned that you already tried flashing different modem just search fr the modem its uploaded by a user ,as now on phn cant search even ketan thread has that modem uploaded just flash via mobile odin n see if it solves
http://forum.xda-developers.com/showpost.php?p=31986738&postcount=6 here is the modem others can work too but since hawkish rom u flashed was based on dmg1 so better try this dmg1

I'll try. Could it have something to do with the fact that my Note 2 was 4.1.1 before I flashed? Is the format of efs different on 4.1.1 and on 4.1.2?

well there may be some change in file maybe few extra or less but that might be an issue as its not restoring the efs backup well try the modem thing and if rectified then don't ever go back to 4.1.1 . as the prob is with the modem so it should solve the problem u facing

No, that didn't help. hawkish extreme actually flashes a modem during installation (which could be where all my problems started...)
I tried now a couple of other sim cards. The problem where one of the lines in the list of network operators is empty seems to be a separate issue. On other cards I also see Telekom.de, which is missing on mine. But on all cards I get
"Registered on Network", when I select register automatically, but Service state "out of service" in About Device->status.
I checked my IMEI, and it doesn't seem registered as lost/stolen.
Not sure what to do.....

Ok, http://forum.xda-developers.com/show....php?t=1918601 worked after
installing a stock rom.
Great!

N7105 factory mode

Hi guys, i seriously need help here. Please refer to attached screenshot.
I came here after flashing sokp 4.2.2 rom, and it prompted me an error saying encryption was unsuccessful. After which, i wasnt able to use my phone since then.
I tried to flash stock rom, and I end up with this. Please dont tell me to search the forums because Ive been to them countless times. I suppose this is a efs issue, because baseband and imei are unknown and I do not have a backup for it. Tried with the writing tool for imei, doesnt work as well.
Pls ask me for any info u might need/i missed out to help with this issue.

I think it's in the efs folder, you have to use a root browser and edit factory mode to off instead of on. It's been a long time since I saw factory mode so I'm not 100%

Thanks for your reply. But even if I off factory mode, will the baseband and imei be unknown?

I'm not sure but if it doesn't the 2 things that might be worth trying are, emergency firmware recovery with kies or mskips toolkit has a rescue package but I think you have to go to skipsoft.net now as the thread was closed
Sent from my GT-N7105 using Tapatalk

It's current value is "OFF"...u have to write "ON"...i know it sounds weird but that is the value. Amd if u don't have any previous back up of EFS then there's nothing u can do at home to bring it back. Same thing happened to mine and i got it repaired from a local shop for cheap...they used z3x box...the problem is my IMEI is correct and network works fine...but everytime i flash a ROM i have to take it to the shop and get the modem patched or else it doesn't connect to network. So go to Samsung service centre and get it fixed by them...they'll charge u more but their fix is permanent.

Alright, it seems like i have a backup of the efs, bt the nv_data.bin file is not included, and i read on other threads that this file is responsible for the imei and all? This backup is dated in aug2013, but it doesnt help in restoring my phone because the efs pro software doesnt see this as a backup file. Im actually looking for one of the thread that actually taught how to edit the nv_data.bin file, but no luck till date.

This thread might help

STILL NOOO HELP
Please me, i have lost my IMEI saying NULL / NULL and im getting not registered on error. I have not backed up ESF folder as well.
Struggling from last 5 days to fix it up. some how i got Modem_N7100XXDMG1 and flashed. After that i have got some fake IMEI.
Tried flashing STOCK ROM 4.4.2, but still no luck.
Read on some forum that MODEM of 4.1.2 or J.B 4.3 resolves this issue but when i try to downgrade from 4.4.2 to 4.3 via ODIN it straight away shows FAILS in RED
IM using Note N7100 K.K.4.4.2
PLEASE PLEASE PLEASE HELP ME.

If you have no backup and the stock ROM did not work, they you are pretty much out of luck. I had a backup but the IMEI didn't come back until I flashed a different modem. I used modem_XXDME4.
If you know what your IMEI number was, then there are ways to write that number directly into the phone. Need to send the phone to someone that has the hardware though. You can buy it yourself but it costs about the same as a motherboard replacement. Youtube "N7100 Android 4 3 imei repair z3x" to see what I'm talking about.
If you don't know the number, don't have a backup, then you'll have to change the motherboard.

You can find your IMEI number on the back of your phone though.. Pull out the battery, it's printed above your device's serial number.

I have my IMEI, i just wanted the solution through software can i change my IMEI or i have to go service center that would cost about Rs. 5000 minimum.
modem_XXDME4 is S3 modem, how can i flash it on note 2 N7100.
PLEASE HELP

@dineshdotcom2000 have you tried different modem? I had the same problem like yours and flashing my region's modem didn't solve the problem. I flashed European modem - modem_XXDME4 - and the dummy IMEI changed back to the original. Maybe you should give it a try.
Here is the link https://www.dropbox.com/s/5mrtz2c6s29ibxt/modem_XXDME4__.zip
I flashed the exact same file on my device and it worked. Good luck :good:

Any way to do it???
Please help

Find a service in india that has a z3x box. They can write the IMEI directly without swapping the motherboard.

just search, a few days ago there was the same problem solved probably in Q&A thread

If your device is N7100...then yes...you can use the stock N7100 rom to repair the device..
Regarding the recovery...you can use TWRP latest version for the N7100 device.
Files can be found in that section on xda...g
