I have the Unknown baseband issue and it seems that i have a bad EFS partition . I have a thread running >> here <<about the problem and the members there told me it seems that it is a corrupted EFS partition
This is the problem :
Well, from the day one i bought my nexus i had the " unknown baseband " in the About screen of my GSM unlocked NEXUS ! ... I dunno how but i left my phone with sim card inserted for some hours and suddenly i noticed that i have a signal and i checked to see the baseband is identified as xxkk6. Now i downloaded the Factory image from google and i flashed it using the Nexus Toolbox and now i dont have any baseband again.
Tried to flash the baseband only again with no luck, It only shows in the fastboot mode but when the phone is in android mode or ( normal mod ) it shows as unknown!
Tried to flash the UGLA4 baseband and the problem persists!
What should i do now ???

The thing is i didnt backup the EFS partition and i don't know how to fix it !!
I have an Unknown baseband and no IMEI as i checked now !!
I have an Unlocked GSM GNEX
would it be possible if anybody uplaoded a copy of his own EFS backup and i might be able to flash it using something and it gets back ?
please help me out !!
try posting in the Q&A section
EDIT: saw that you did... but posting here probably won't help much either.

The EFS contains our IMEI so I don't think anyone would share their EFS with you.

Just an FYI this is the wrong section, it should be posted in Help & Troubleshooting.

You didn't say how, or what you were doing when you lost them but if you were trying some of the 4.4 ROMs it will appear that way on some phones, mine being one. Download a stock ROM and flash it after wiping all, don't have to wipe external SD. Or if you still have one of the ROMs installed pm me and i will walk you through getting it going. If it's unrelated to flashing, follow the advice given.

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

No one helped me and i think no one wont help you either i dont have M9 now if i had i'll post a efs backup immediatelly
There is no efs partition on HTC phones. It only exists on Samsung phones.
You probably flashed a GSM RUU on a CDMA device or vice versa. Return to your original firmware and hope that you didn't damage the phone unrecoverably since the partition layout isn't the same on those two variants.
