Hi everybody! I have a problem with EFS partition, I'll try explain my problem on the better way possible because I don't speak english.
After several flash via odin and CMW the EFS partition is broke.
When I flash the stock ROM with odin the IMEI is there, but when I flash a Custom ROM the IMEI dissapears and I don't know how fix this!
I tried with EFS pro but print an error:
Device Connection: okay!
Root Access: okay!
Detected 'efs' Partition Location:Failed!
Error:Can't Locate Mount Point!
EFS backup Failed!
Also, before all that, I tried with Galaxy Toolbox, and I did a backup but, this backup not works. I know that because I tried restore the EFS partition on the Custom rom and the IMEI isn't appear.
Somebody can help me please? I want restore the EFS partition.
My SGY is GT-S5360L
If you need more information about my phone, just tell me.
Thanks for read!
Greetings!
Hy everyone,
I'm a little desperate now. my i9500 is stuck at Samsung logo even the animation sound that not complete, i had mokee rom 4.4.2, made a restore from a previous nandroid backup, barebone prism rom V3.0 worked perfectly, installed nandroid manager and restored some access point passwords, worked perfectly so far, my phone reached 1% in battery then turned off after a while. when i wanted to reboot it, the phone freezes in Samsung logo.
Recovery: Philz touch recovery
I tried everything that i know about,
1° reboot in revocery and restore from a previous nandroid backup (NOT GOOD)
2° reboot in recovery, perform a full wipe, restore from a working previous backup (NOT GOOD)
3° reboot in recovery perform a wipe reset (NOT GOOD)
4° restore via odin in download mode last stock firmware for my phone I9500XXUEMJ8 (NOT GOOD)
5° i tried mounting all partitions for check and .... Eroor mounting /efs!
i checked efs folder with aroma file manager ... 0 files inside :crying:
i had a previous backup for EFS found in kies in .tar.gz format
i tried to restore it with several methods
http://forum.xda-developers.com/showthread.php?t=2392632
guess what ?? NOT GOOOD
i tried manually to copy files in EFS folder and changed the permission for EACH file with the same permission from the backup in my laptop then i reboot in recovery, the files still inside but when i reboot the system, the files are gone
i've read somewhere that there is two type of efs , and the efs made by some old stock rom won't work for a new one (Personally i don't know but like i said i'm desperate) so i downloaded from sammobile the FIRST rom that was in my phone and put it via odin (Re partition was never checked) then i tried the methods above ... :crying::crying::crying:
because i only have .tar.gz i tried restore it and witout rebooting the phone ===> (EFS Folder not empty YET) made a backup in .img format so that i can restore in /dev/block/mmcblk0p3 still not good
so i REALLY need your help and plz do not ask me to go to service center, warranty binary status is 1
Thanks everyone and have a good day

you need to flash a efs partition via odin. in tar format.
the your phone will boot normally. unistall knox and only then you could put your efs backup to the phone.

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

Flash a lollipop modem and your imei is back.

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.
I was doing some rather regular restores from TWRP when all of a sudden I lost my Baseband with no [apparent] way to recover it.
I flashed 4.4 and 5.0 stock ROMs. Nothing. I flashed the modem [CP_N9005XXUGBPB1_MODEM.tar.md5] a zillion times. No luck.
I tried flashing this baby, made by a fellow XDA'er:
http://forum.xda-developers.com/showthread.php?t=2507403
It's based on a script that supposedly fixes this issue. Also no luck. Still stuck on "unknown" baseband, no mobile network
Any help is MUCH appreciated. It's 00:18 and for the past 3 hours I've tried to recover from this...
P.S.: I have a full backup of ALL my partitions, so I think I can recover from this. Somehow...
Can you restore your EFS folder from a backup?

Well, I tried to restore the entire OS via TWRP from my full backup. And now, since you mentioned it, I also tried restoring ONLY the EFS. No go
Do you have an actual backed up EFS folder .

I have these files among my TWRP backup files:
efs1.emmc.win 14 MB
efs2.emmc.win 3 MB
efs3.emmc.win 3 MB
I always back up all partitions.
Upon restore, I can see an "efs" folder in the root (along side etc, acct, mnt etc) but the folder is empty.
I have NOT taken any manual backups of the efs folder (as in copy the folder itself), nor did I use a tool such as EFS Professional. I found out about these too late
I was hoping that TWRP does what it says when it "backs up" data. Am I to understand that I just destroyed my phone because TWRP didn't back up my efs?
Sadly thats not an EFS backup .
A shop with a JTag should be able to fix it .

Ouch. Much appreciated, despite the bad news .
I'm quite angry on TWRP now. What did they mean by "efs" backup, if there's no actual backup?
So this means they have to access the phone motherboard to do... what? What should I ask them to do? Flash me a new IMEI?
