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:

I have already used this modem. Right now i have some fake imei with "004999010640000/1 i want to replace this IMEI with my original imei on Note 2 N7100.
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

IMEI 0049...

Hey guys soo i rooted, then got a recover but forgot to backup and then i did advanced wipe where i deleted everything. I then got a custom rom and everything worked fine until I realised baseband was unknown and imei was nowhere to be found. I then went back to stock firmware via sammobile. Baseband is back but imei is now 00499.... I've looked for hours and can't seem to find a way to get it back. Ia there anyone who can help? Perhaps a software to rewrite imei? Any help is much appreciated guys
EDIT: i can get my hands on another note 2, can i simply copy the efs folder and replace it into my note 2?

INVALID/00 [re-write] IMEI without any backup

As there's no solutions yet for the problems above hope you guys or some devs. can help/produce some solutions.. more specific situations:
1. you never backup the imei numbers
2. device totally bricked (fatal error/failed while flashing fastboot rom).
3. device fall into qhsusb_bulk, which no fastboot or recovery access..
4. bring it back to live with testpoint process(hardware) jtag likes on other devices.
5. its back to live with known baseband, esn but the 00/invalid imei.
what to achieves :
1. find ways to bring back its default imei numbers.
ive do some research and ive start a thread on miui forums too
you can see it here http://en.miui.com/forum.php?mod=viewthread&tid=166001&mobile=2
some people does have this problems too.
Anyone who wanna contributes some help some posible files needed to make it work:
1. A QCN backup from working/normal phones
2. NV backup files, again from normal phones with imei

I too lost my basesband, imei and wifi mac address.
But i got them back after restoring a few efs partitions that i downloaded from a blog I found.
It seems that I cannot post any links so i added some spaces in the url
Here is the url- www . amw-android.my . id/2015/05/fix-imei-baseband-xiaomi-redmi-1s.html?showComment=1445024870694#c3080464083769125141

did that procedures.. at the 1st try but seems its not working for me as my situation is Baseband is safe (not unknown) but the imei was 0..

CLOSED!!!! Since i succesfully write down the SIM1&2 IMEI, but still cannot get any signal, seems EFS partitions totally breaks

I had the same issue. Then I flashed with the fastbootrom country specific, i did India based using miphone flasher. In this you need to specifically select flash_all.bat, so that it erases the entire IMEI and updates with default from your phone. Once you do that, it restores the baseband MIUI rom. Then you can flash TWRP and then any custom rom. This worked very well for me and I could use my phone. Also the both the sim cards are restored.

Strange that, after flashing the Indian Fastboot ROM, i ended up with known Baseband, Wifi address. But IMEI still invalid or 0.
Any help please?
Thanks

Note 2 IMEI Generic 0049** Exynos how to restore without efs backup?

Hi Guys,
First of all sorry for my bad English.
So I decided to fix my old Note 2 that I ruined few years ago by Flashing it to hell!
The problem is : Generic IMEI , like 0049******* .. I tried almost everything but couldn't find a solution .
It has a exynos processor so Mobileuncle tools, MTK, EFS Pro etc. wont work on my Note 2.
I don't have a backup of the efs folder. How can i modify (rewrite) my IMEI ?
Thanks in advance!

Did you try flashing stock carrier rom with odin?

i will subscribe to this thread... i had this issue yesterday and same i am on Exynos..
a Null IMEI ... no EFS backup

Galaxy S20 ultra G988B/DS SIM Network Not available (status ng) after flashing stock ROM

Hi Guys !
Greetings to y'all!!!
I'm honored to be a part of this prestigious community at last and looking forward to give back, someday soon. My huge respect for all the contributing members, I have been using this forum to get help since 2016 and without even posting anything I've always managed to get helpful information to resolve every problem encountered till now ((rooting & flashing)).
:'D
So here goes my first thread:
A friend of mine recently tried flashing stock ROM on his SM-G988B/DS since his update firmware option wasn't working for some reason. Even though it was a success, in doing so he flashed wrong version of firmware and caused network failure, flight mode if tapped got stuck (greyed) (wrong modem was flashed). There was no backup and original firmware number wasn't mentioned so I tried flashing different versions of firmware (U1,U2,U3,U4 & U5) and finally got it working on flashing CP(modem file) of G988BXXU5BTJ3.
However, for some reason I still was unable to make a call, so I searched for it and found out that by dialing *#0011# my IMEI status is NG which is bad , even though my IMEI number is still intact as found on the back of the phone. I researched a bit further and found out that this has something to do with the EFS file and whilst going through comments in another forum I found someone else had the same issue and got resolved by deleting nv_data.bin file and its backup and IMEI folder in EFS file after rooting and reflashing stock ROM. I tried the same but found that nv_data.bin was missing in EFS folder, so I backed up EFS file and deleted just the IMEI folder in it and reflashed stock ROM, have tried flashing different CP versions aswell still no success .
I've seen some videos of Chimera IMEI rewriting and certificate patching and Z3X tool on youtube but in their case IMEI is missing and I don't want to go for those solutions for the instance. I'm wanting to learn from all this exercise and want to know whether what is what and how to resolve this manually (maybe by writing some hex code or script etc) if possible.
Summarized:
Phone: SM-G988B/DS
ROM: Stock (G988BXXU5BTJ3) (rooted)
Status: SIM Card Registration failure ( IMEI status NG)
IMEI : Intact (As on the back of the phone)
EFS file ( nv_data.bin and .bak missing)
Previous Status: SIM Card was working fine before flashing ROM
Your valuable suggestions in this regard shall be highly appreciated.

First, do a TWRP backup, all partitions including efs & modem.
Open the root explorer app, open the efs folder, delete the files named nv_data.bin
, nv_data.bin.md5 & the folder called imei. Then open twrp, wipe all partitions. Flash the latest firmware with Odin.
