No basisband, IMEI unknown: EFS corrupt? - Galaxy Note II Q&A, Help & Troubleshooting

Hello,
i have the note 2 lte from my friend. He tried to root but i don't know what he did. He says that he flashed a "bootloader" but it was for the s3. I think i took the auto-root but flashed it in the "bootloader" and not "pda" in Odin.
The phone didn't boot.
I flashed a complete stock rom. Now it boots but IMEI is unknown and no basisband information. I made a first EFS backup here. I tried to flash a modem but it didn't help.
After several tries i get the "hidden menu" with EFS Professional. Now the NVTool works. I can read the IMEI over it. In the phone is the right IMEI so i don't need an injection.
Restore the EFS with my backup above don't help. I tried to make a factory default with Kies but it didn't help.
What is wrong? What can I do? Maybe the partition table is corrupted and so it has no baseband firmware? Why doesn't it show his IMEI when the NVTool (EFS Professional) can read it?
Thanks for your help and sorry about my bad english.

No, because my friend flashed "something" in the bootloader and bricked the phone. He gave me the phone.
I flashed a stock firmware over Odin, the phone boots and at this time it shows no baseband version and no imei in the settings menu.
I made an EFS backup but it was (maybe) already corrupted. I flashed older stock roms, modems only and tried the factory reset in Kies, nothing helped.
The NVTools in EFS Professional 2.0.35 shows me a correct imei number!

Unable to flash anything but a stock rom.

I have a glide that for whatever reason only works on a stock AT&T ROM. either the gingerbread or the ICS but only stock ROMs. Any custom ROM I flash the phone looses its IMEI and will not function on the network. Once i either restore it from a backup or use the Samsung Kies app to do a firmware reset the IMEI is instantly back and the phone runs fine. I have a backup of the EFS file and once I've flashed a custom ROM if i restore the EFS still no IMEI I am at a loss up to this point any help would be appreciated.

I have the same problem and I get the generic imei, I also have an unknown baseband
I'm presently having issues with my phone displaying generic IMEI, but I can still use the phone on my network. I dont know how long I was using this for, but I can't seem to restore my IMEI from my EFS folder. I have a backup of my efs from November when I unlocked my phone using FastGSM. There are some posts in the SG2 forum and youtube videos but they are inconclusive with the testing I have done to restore my stock IMEI. I have a stock EFS backup that I'm attempting to hex edit but it isn't a rogers one so I'm really fingers crossed hoping for the best.
In the meantime, try and revert back to stock GB on your phones grabbing the firmware from Samfirmware ... sometimes you'll get your IMEI back, if you do backup the efs folder on your phone ASAP save it safe .. email it to yourself or do something static where the file will be saved in a unique place that it can't be changed.
I'll post a how-to if I get mine restored .... otherwise I'm really not sure what to do. It's super complicated to get it back without sending it in for service.

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

In samsung mobiles the first thing to do before doing any rhing custom is backing up EFS partition and modem and leave them in a safe place .. U could fiz it by patched modem but when u get that defult imei u loss ur efs partition .. Now u had to fix it by z3x box or spt box

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?

IMEI unknown

Hi
I flashed to stock Jellybean and rooted my GT-i8160 (UK) version. Everything seemed fine except my IMEI is blank and shows 'unknown' in settings/about.
I did not backup the EFS partition/data but I understand that the IMEI is not stored there on the GT-i8160??
Anyhow, what do I need to do to write/hexedit the IMEI back to the phone so it can detect a SIM?
Baseband displays correctly.
Please help.
thanks.

Well, I did a bit more research and i think the only way forward with this is to use it as a brick or pay money out for hardware that can restore the IMEI back.
Can anyone suggest an altenrative method restoring the IMEI back?
I would highly suggest you finding stock gingerbread ROM on Google then open Kies and update it there to jelly bean. If that will not fix then I dunno.

Can someone provide me their g960f EFS folder? (NOT the IMEI or anything sensitive)

Long story short, I screwed up and I deleted everything from my EFI folder. No backup (captain hindsight) Doing a stock flash with Odin seemed to kinda restore the EFS, but I have generic IMEI and no network support. I have my IMEI (its on the back of the phone). I tried to write it with z3x, but it gives an error. I think its because my EFS is not "correct". If someone could provide me their EFS folder. NOT the IMEI folder or anything that you consider as sensitive (beggars cant be choosers) I would be grateful.
I am struggling 3 days now trying to get my phone back, every forum post and youtube video about restoring IMEI is a scam and/or full of viruses.
Any help would be appreciated, every guide that seemed legit is outdated and doesnt work on s9 with android Q.
Thanks in advance.

Did you ever manage to get this sorted, i have exactly same problem?
If your imei is screwed up try flashing the proper base band. Imei isn't stored in efs. And the imei is based on a cert file. Cannot just be written to the device
