Hi,
after flashing new rom and modem I have lost imei number, I dont have any backup of efs drive....
Is there a way to restore it?
I tried flashing back to older modem and stock rom, but no luck. i have still no imei and baseband unknown.
Please help
Flashing a stock mod fixed this; got loads of help from OP
Flash your original modem, or any latest full ROM in odin

We did try that a few times, it did not work. I was genuinely surprised as we used a Swiss stock rom that restored the imei number and network connectivity.

Hello there,
I live in India and my Note 2 is a Poland made and running with 4.1.2 stock ROM non rooted. But the device status was shown 'modified'. Due to that (i think) i was not able to get any updates. So i decided to download and flash 4.3 ROM via odin. I did exactly and flashing was success. But after that i was not able to connect to my mobile network. It shows the coverage, base-band version, operators around me, IMEI...etc. But failed to register on network. Sadly i found that my IMEI was changed. Then i searched in xda and found out few modem patches. To flash them i rooted device and installed recovery. Then flashed DMG1_MODEM and modem_XXDME4 but nothing happened. Phone is still not registering to network.
What to do ?
I assumed that your device history was imei null or efs corruptted which has been fixed under 4.1.2 version.by upgrading the modem it will surelly broke your efs again.use special box to repair the network, nothing else you can do.
you have to flash the factory-image via odin (i think this would be the poland one in your case). you will get this on sammobile.com. with this it recreates your efs including your imei. (had this problem also)
after this you can try flashing a different rom, but don't forget to backup the efs

Is it safe to downgrade from 4.3 to 4.1 just by flashing factory images via odin ?
If you have flashed the latest bootloader MK4,its not possible to downgrade to 4.1 as of now...

So using the phone like a tablet without GSM is the future for me ?
Hi all,
I'm planning to flash my phone back to 4.1.1 via Odin and then to to 4.1.2 firmware, found on Sammobile to carry out the unlock method.
However, I am on the DMF2 baseband, and have heard that flashing a new modem over this will mess up the IMEI.
Will this happen if I'm only flashing a stock rom over it?
Thanks in advance!
I used to flash 4.1.1 stock ROMs onto my N7100 from 4.1.2
I would go into a bootloop after flashing it but booting to recovery and wiping data and cache solved my problem. Just backup your EFS to be on the safe side though

flashing new modem will not mess up IMEI.
but to be safe, back up your EFS before you do.
Normally IMEI will be messed up if EFS corrupted during the flashing.
Most of the time, it will happened if you change ROM with different base version (and normally happened when you never read the instructions of the OP very well).
So, when you want to downgrade, please do backup your EFS first (especially if you are coming from 4.3, due to different bootloader/partition of internal storage).

I need Need N7105 EFS backup file, can any kind soul do a backup and upload here?
For 4.4.2. My baseband is unknown, I need this file to recover it
EFS is original for each other phone and IMEI too

Hi! Just for you to know, this happened to me once, and I fixed it only by doing a factory reset from recovery, THEN installing a stock rom with Odin. Unknown baseband is just an issue with something being corrupted, and can be fixed with a full 4 part Odin stock ROM. Don't worry, it'll fix. Just do a factory reset from recovery before installing the rom.
Happy flashing And don't forget to thanks if I helped you
Hey Guys,
So i recently flashed from stock to CM13 via TWRP Recovery which was installed via Odin.
After doing this my device is now almost operating perfectly (Exceptionally better than it performed on Stock),
except i now get Baseband Unknown, IMEI Unknown and IMEI SV Unknown.
- Samsung Galaxy S4 Mini GT-I9190
- I do not have any backups of /efs! (sorry!)
- I have my IMEI number written down
Any Solutions to this ?
Thanks in Advance,
Dizzy.

Can you please elaborate, i'm not sure what kies does or how to use it,
I have tried flashing couple stock roms and all had the same problem.
Install Samsung kies(jellybean) or kies 3(for kitkat). Then click on tool tab and click on firmware upgrade and initialisation. Enter the phone model and S/No as shown on the back of your phone. and it will download your stock rom which might help you restore your imei.

Hello XDA
im use N900T
previously there was no problem on my N900T , until one day I install a custom ROM N9005 for N900T and I did the patch wifi and bluetooth .
now my maximum signal only at EDGE , could not be 3G / 4G even though I 've been back to stock ROM
if anyone can help me find a way how to get back to normal.
I am frustrated with this because it has been nearly two months , my phone can not be used :silly:
thanks for advanced
Did you try flashing the latest stock rom from sammobile.com for the n900t?

I 've tried it, I now use N900TUVUFOL1_N900TTMBFOL1_TMB-v5.0.1 :crying:
Maybe the EFS folder got corrupted? If you have a backup, try restoring the EFS folder with a stock ROM.
After flashing stock, install the Samsung Phone Info app to ensure that the bootloader, baseband, etc. all show OL1.
You confirmed that the model # n900t is displayed in download mode?

i'm not have EFS backup
this my screenshoot N900T in attachment
It all looks okay and if the imei did not come back, then the efs folder will need to be created and copied back to the phone.
okay thanks for answer
i change usb port charger and my signal is back
