I think some other partition was corrupted and thats why the twrp efs restore didnt worked (just a twrp efs restore).

I did following: (you need a efs backup!!!)

Folow exactly this guide and do all partitions, DONT! skip the efs partitions (we have a twrp backup)

Now some further steps are needed:

1) When you put in back your battery, boot back into twrp and restore your TWRP EFS Backup!! Dont boot in the OS!!!!
2) Then reflash with odin a stock based rom without any other checkboxes (NO EFS PHONE CLEAR, NO NAND ERASE ALL!!!!), just a normal odin stock rom flash
3) Let the phone reboot into OS and YES: Baseband working again, EMEI working again
Hi, I have the same problem as you did, my baseband is showing unknown and the imei is showing null. This happened when I was installing a different modem via ODIN. I do have a EFS backup, however, it was done with philz recovery instead of TWRP and has 4 files ('efs.ext4.tar'; 'efs.ext4.tar.a'; 'nandroid.md5'; and 'recovery.log'). Are these the same that you would get with a TWRP?

I also have another efs backup that I did which is one file only, 'efs_20140531_122400.img'. Would I be able to use this for anything?

The phone is an N9005 on Kitkat.

Thanks for any help in advance and please let me know if you need any other info.



Just to let you know,

I had tried flashing flash latest full UK NF4 system before and it didn't work. However, desperate as I was, I went again and gave it another shot and incredibly enough, it worked!!!! Phone is back together again!!!! Yeeahh!!! There goes an incredible load off my shoulders. I guess I did something in between that actually helped, we may never know.

But now even if i restore my backup in TWRP or via the Windows Batch Backup Script, my Baseband and EMEI and EMEISV is still "unkown"

Can s.o tell me the steps i need to do, to rewrite my Baseband and EMEI with my available EFS backups?

What i have:
- EFS Professional
- 2 different EFS backups in TWRP
- 2 windows back tool EFS backups (i mean this script:
- Working WIFI
- Working BT
- Stock N9005XXUENA6_N9005OXXENA5_N9005XXUENA2_OXX file(s)
- Stock N9005XXUENB4_N9005DBTENB1_N9005XXUENB1_HOME file(s)
- Stock N9005XXUENB7_N9005DBTENB2_DBT file(s)
- Odin + 9005 PIT Files
- Correct SerialNumber in DeviceInformation->Status

I'm on the new Bootloader and KitKat OS

Thank you very much for all your help!

Best regards,

Hi Hundsbuah,

I upgraded my Note 3 9005 Hong Kong Version 32 GB from Jelly Bean to KitKat without taking backup of EFS and now I have IMEI Null and Baseband unknown. I found backup of other user's note3 EFS at "". So, if I tried EFS restore from above link will it resolve my IMEI null and baseband unknown issue?

If I've helped you, hit the Thanks button!
