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..

@Bajanman sorry but that guide is useless for the LTE Note 2 variants. Look for guides from the LTE Note 2 or the North American SGS3 as your main starting points to try and solve this. (My T889V LTE guide has some links to those.)
One method I'd like to hear reports about is the reboot nvrestore one, I've seen it discussed mostly on a Verizon SGS3 thread, but nothing IMHO says it wouldn't be relevant for the HSPA/LTE versions either.
Edit: The EFS and other related partitions are of a significantly different layout between the dual-core SGS3 and the LTE Note 2 or GT-I9305. adb reboot nvrestore doesn't seem to do anything on our devices.
Good luck,
Darkshado

hey i didn't find anything...i've heard that there's some custom roms that contains EFs backup that can solve my problem is this true ? if so can anybody give me a link for one of those roms ? thank you

Try to flash with odin the stock rom that you got your note 2 with. It happened to me once where i flashed something and lost my imei. I didnt backup or anything. After i flashed the stock and unrooted my phone my imei reappeared and my phone worked again. BTW it was a att note 2. I found the rom somewhere at this forum. No rom contain you Efs i think(could be wrong) but each phone has it own imei.

[Q] Generic IMEI after OTA 4.3 upgrade

Hello to everyone, I was wondering if anyone can help with this. I have a Galaxy Note 2 branded by an Italian company (3hg Italia). It recently received its update to Android 4.3 (update N7100XXUEML2). It was the official update OTA, the phone is not rooted and it had the stock ROM on it. The update somehow messed up my IMEI making it appear as the generic 0049 forcing me on "Emergency calls only" mode. I already tried flashing the same ROM with Odin and repeating the update with KIES, but while the updates always results successful the IMEI remains 0049. I never made a backup of the EFS folder for this phone since I haven't rooted it or flashed any different ROM on it yet. There is any chance that the phone made an automatic backup? I live in the States right now and Samsung tells me I need to ship it back to Italy to have it fixed, but that costs a lot and would take forever, and I would much prefer try to solve the problem locally. Any suggestions would be greatly appreciated, if not for any fix that I can try myself, at least some place on the West Coast that can fix the problem!
Thank you!
Lorenzo

Oh I forgot to add that because of Hardware problems I recently sent my phone to Samsung and they replaced the motherboard, which fixed the problem I was having. I don't know if that could be related!

I'm afraid that fix works just if you have your actual IMEI, I instead have the generic IMEI that starts with 0049. But I will check it out! Thanks!

Then you should simply flash another modem from here : http://forum.xda-developers.com/showthread.php?t=2044937 ... flash a custom recovery first.

So I found someone nice enough to give me a hand with this situation, but still no luck yet! Here what they say:
At first glance, the EFS data on the phone was corrupt. I re-generated
that data and restored it to the phone without success.
The GSM radio itself is operational, and the firmware for it is
installed and functional. diagnostic data flows to the towers and back
to the phone but it's not reading the IMEI from the copy of
nv_data.bin contained within EFS. I've re-generated and installed
those files as well, again with no luck.
I rolled the device back to it's original factory firmware and radio
baseband, then ran through the update for the radio baseband, which
also regenerates the contents of EFS, and still no luck.
Given the situation, anyone have other suggestions?

try flashing your official firmware through Odin. other users solve their imei problem by doing that. see also if you can access engineering mode with that official firmware.

lets wait for others specially those who are expert in android for some advice. I'm just an ordinary security guard so i can't help you much with your problem. what i have suggested you from my previous post was the last thing I did when my phone finally worked. for 4 days i been searching for solution because i also have an IMEI problem. i flash back to official rom, flash patched modem, flash other roms to no avail until such time when my phone doesn't boot because of broken partition :laugh:. if you still have warranty restore it back. if you're already out of warranty and you have money, you can it send it to service center.
P.S.
you can also try this if you have courage. i was able to make some secret codes work but i have'nt tried if it works with engineering mode by modifying hiddenmenu in /efs/carrier/hiddenmenu. use efs explorer to open hiddenmenu and change it to ON.save it and restart your phone and see if engineering mode work. remember that you have to be in official firmware and also rooted to do this. if its not working then you'll just have to wait for a much better solutions from devs.

Same question
I have the same problem, as owner of the thread. Any help?

Help with ZERO networks!! Before I burn this THING!!

Okay story so far, got Zuk Z2 from BG China to replace Mi5 that had a tumble
After a couple of weeks I decided to flash Custom Rom (LinageOS *UNOFFICIAL), seemed fine then I lost Network totally on both SIMS.... Zero bars! I've tried all sorts of ROMS and flashes of Baseband firmwares but to no avail. Now I think I've confused myself.
So if anyone has any advice before I cast this device from a high roof it would be most appreciated.
Thank you :good:

You flashed already different basebands via fastboot, erased modem after that?
Tried flash stock ZUI via qfil?
After all no network? IMEI's are there?

When it first gave up network I checked IMEI and it seemed to have duplicated them for both sim but after I QFIL back to ZUI 2.5 they returned perfectly... I've gone through the whole erase modemst process but still FUBAR....
Even stripped the device down to bits and checked the internal connections.
He strange part is I get the emergency only msg on sim so guessing the network is recognised but the signal is -90 dBm at best, getting to as bad as -130 dBm.
Even considering writing the IMEI from old bust Mi5 to handset to see if this would help...

Yeah I guess every other android and iOS device I've either rooted or jail broke was pure luck and the huge amount of posts on many sites including Lenovo regarding this baseband problem are all very similar 'lab rat' experiments.
Thanks for the constructive advice and answering my plea, great to know that xda developers are attracting helpful and intelligent like minded users and owners....

I had a dabble with QCN and managed to replace corrupt IMEI's but still didn't help. Can't be sure the BASEBAND was correct though.. I'm yet to try a full FACTORY DEFAULT configuration as suggested but will be this week.
Been suggested the IMEI may be blocked for some reason but seems unrealistic as it was working prior to FLASH.
