gt-i9505 imei null / null lost baseband - Galaxy S 4 Q&A, Help & Troubleshooting

Hi, 1e thing i did was rooting device and backup efs folder all partition in efs pro
after that i installed phil recovery and make a compleet nandroid backup.
after 2 months playing with customs roms, and the latest was Omega 8, my signal was some times dropping and i'am getting the stopsign.
I find out that when the signal stops, my imei and baseband also disapeard. verry strange. So i tried to recover efs folder but this didn't solve the problem
even when i format efs folder en then restore, the efs folder is filled, but still no joy. also tried standard stockrom
where i made the first efs backup from and i tried nandroid restore, but still nothing.
I think there is nothing to do more and sent it to repair center

Can you try to flash Factory Firmware and see if your imei goes to 00/0.then restore your efs

i'm going to try that. Thanks :good:

I flashed factory-rom, that didn't work.
Also the service menu won't pop up *#0011# -> menu back -> menu keyinput 1
maybe it's hardware failure

On the N9005 the IMEI is no longer on the EFS partition (mmcblk0p11) but instead in some other partition - I think mainly in MS1 (mmcblk0p12) with something else (backup?) in MS2 (mmcblk0p13). There might be something else in mmcblk0p17, mmcblk0p18 and mmcblk0p19.
If you do not have any backup (including a larger "debrick backup" - search for that post) you can try to see which one of the partitions I listed above was supposed to be the backup of what; and if that fails there is a more complex procedure described somewhere in a thread on XDA - involving manually hex-editing your SN and IMEI from under the battery or the original box of the phone.

What about the "unkown baseband"? How can this be fixed?
Ok a managed it to get all back working, incl. baseband, emei etc (but you need a twrp efs backup with all 3 efs partitions --> simply a twrp backup)
If some others have the same problem, here you go:
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 http://forum.xda-developers.com/showthread.php?t=2567133: and do all partitions, DONT! skip the efs partitions (we have a twrp backup)
Now some further steps are needed:
IMPORTANT:
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.
Cheers
--------------------------
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.
Cheerio

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 "http://forum.xda-developers.com/showthread.php?t=2447342". So, if I tried EFS restore from above link will it resolve my IMEI null and baseband unknown issue?
Regards,

[Q&A] Restore EFS from Nandroid Failed (Solved)

Hi Everybody,
I'm really disappointed. For the second Times, I've corrupted my EFS partition. IMEI is empty, as the baseband...
The first time that I had this problem, I could restore the EFS using the fabulous fix from Fireasusman : http://forum.xda-developers.com/showthread.php?p=47014662#post47014662
But this time, It didn't work.... I'm really really sad.
Before trying to restore the stock firmware ( My problem was coming when i tried to restore stock firmware before to sell it) i made a Nandroid backup with TWRP recovery. I've an EFS/MODEM backup in this Nandroid.
When I reboot into recovery, and go to restore, I can select EFS, and it seems restore It. It wrote : Restoring 2 partitions/Restoring EFS/restoring EFS2/restoring EFS3/EFS Done/Restoring Modem/ Modem Done...
But after reboot the problem is Still There...
I'm really Angry, I lost 400$ and I don't understand why my Nandroid Restore of EFS failed...
I also try to flash modem with ODIN but it still Failed.
Note: I was an temasek CM12 (android lollipop).
Thank you very much for every help.
1. Flash STOCK ROM and take a look how it works. Sometimes only flashing it recovers the EFS folder.
2. Next time use this APP for backup/restore your EFS.
Really thanks for your help.
But i've allready try to restore stock ROM. At least twice. But efs is still corrupt. And the phone never arrive to boot...
About how many time I can consider that flash stock ROM will not repair my EFS partition ?
I've allready done twice...
Ok... I solved my problem.
As I explain in first post, I'had a EFS backup with a Nandroid Backup. But when I restore with TWRP, the problem was still there. No pin, No baseband etc...
I only delete the EFS folder using root explorer. I reboot, and it was OK. EFS folder was rebuilt automatically.... No more complicated than that...
Good finding

Because the IMEI is not stored in the EFS folder.

[Q] Help. Can't restore EFS Backup

My problem started when i tried to install a custom ROM. I was on Omega ROM v23 and all was fine but i tried to install other ROM and after the install was complete the phone turned off. I pressed power button but nothing. So i pulled the battery and the phone started. But my surprise is i have no signal and no IMEI??? I restored my nandroid backup from Omega ROM and my IMEI is back and signal but every time i turn on WiFi the phone reboots in Factory Mode and wifi turns off. After that i downloaded ES File Explorer to verify my EFS folder and is empty. So i said no problem i have my EFS backup. I did it manually and with 1 app from Google Play in .img and on tar.gz but the app doesn't restore my EFS backup. It says i have to use other app for that? However after downloading the app and restoring EFS it says i have to reboot but when the phone is back EFS folder is empty so no working. If i try to copy files it says there isn't available space. Please help. Any suggestion is appreciated.
PS: My model is N900w8 from Telcel with NH1 Bootloader and Baseband
Restore EFS through the restore option in recovery, or try rebuilding nv data via the service menu

EFS lost on 5.0.1 on 910C

Hello everyone.
Got stock 910C with 5.0.1, today made root and twrp. backed up EFS with terminal emulator (got efs.img) on my sdcard.
Also made EFS backup with twrp.
Flashed custom 5.0.1 rom, right on welcome screen - lots of FCs. Wipes didnt help.
Returned back to backup of stock rom but now EFS got erased. no IMEI and cellular network.
Tried restoring with terminal and twrp - no luck
Can someone advise?
Try to make a software repair with Kies and report back
Dont forget, EFS doesnt contain any IMEI certs or CAL data, so if u clear EFS partition IMEI willl be the same, only SerialNumber will be wiped

can u clarify please. how can be serial number be wiped?
EFS partition -> SerialNo, Bluetooth, WiFi and password + settings
IMEI certs -> SIM LOCK, Imei number. CAL data
As u can see EFS erasing will never destroy imei number

then why did i lose baseband?
When you tried to backup EFS or root you lost MD5 signature of IMEI parititon. Now its gone. In some cases it can be undone by flashing to STOCK firmware.
Please check the screenshot for correct location of EFS partition and M9K partitions
i did restore my EFS by reinstalling stock 5.0.1 with odin.

If you did a backup then you should be able to restore that backup using the same method. Eg: If you used an app, that app should be able to restore the efs folder.
The problem with the EFS folder on the latest versions of Android is that it doesn't contain the IMEI, last time I checked. The IMEI is now stored in hidden partitions, which is why when it comes to backing up this important stuff I recommend Wanam's EFS Backup tool from the Play Store. Not only does it back up the EFS folder, but also backs up those hidden partitions as well as the modem..
In this instance however, Lennyz1988 I believe has the right answer.
