[HELP][Q] I9500 Stuck at samsung logo + an empty EFS folder

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.

[Q] I9505 auto restore EFS after its delete, why?

Hi,
I have Galaxy S4 (I9505) and after official update, I have faced error of unknown baseband and lost IMEI (null/null). Problem was, that IMEI and baseband were working only, when I fully discharged phone, put it on charger and turned it on. But when I called once, I have lost IMEI and basbend suddenly, same for the second start after 0% battery. I have made EFS backup via terminal emulator and "dd" operation - (http://forum.xda-developers.com/showthread.php?t=2433966) and to successfuly recover EFS, I had to delete it first. But when I delete EFS and reboot, EFS folder is not empty but is populated from somewhere. I am not able to get into "permanent safe mode" so I am unable to restore EFS.
Anyone faced the same problem? Do you know, from where is EFS folder auto-populated? I have also tried old stock ROM, problem is I cannot downgrade to original ROM before update, it was 4.2.2 and I can't downgrade bootloader. Newest 4.3 ROM also doesn't solve the problem.
Thank for any ideas

Anyone?

[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

If you don't have a backup and flashing official firmware doesn't help to revive it, nobody else can help.

I finally managed to repair the damage caused by EFS and by when I go to the root explorer I had a clean empty folder EFS whatever I tried to install the new ROM moaning and costum and wipe reset Factory me is always the folder EFS empty my IMEI was correct as it was under the battery, the only thing I had a bad signal and wifi is deenergizes.
To repair the damage I'm desperate to be ordered from stock rom sammobil version 4.4.2 because my phone was slow I then ordered stoc 5.0 then I root the phone and ordered phils latest recover and then I went under the option to mount and put the mount seytem then I have connected phone to a PC and install the adb shell on the computer I Open cmd and typed it
adb shell
su
mke2fs /dev/block/mmcblk0p11 ( skip to next step if fail)
mount -w -t ext4 /dev/block/mmcblk0p11
reboot
This will create a generic EFS files on device
Root explorer/efs and delete factorymode(OFF) and replace with factorymode(ON)
reboot in recovery wipedata factory reset...don
This last what it says to me it was not necessary because I went in and looked exporer root file factorymode where it has been on only one I did factory reset and that's it I got back EFS files and I am so done with all programs EFS Bacup :good:
P : S: because I have a bad signal or should now install new modem in order to find the best signal

EFS folder deleted and not recoverable from TWRP backup - Verizon Note 4 N910V

Guys i need help as I have lost my EFS folder. Summary of how it happened is as below:
Initially I had Note 4 Verizon version running Lollipop 5.0.1
I used a method to turn it into Developer Edition (DE) and I was successful in doing that.
Once got through that I installed customer Recovery (TWRP) and made a backup for it (including EFS folder and everything else)
After that I got SUPERSU installed and root access to my mobile.
Everything until this point was smooth and no issues until I installed XPOSED FRAMEWORK and my mobile got stuck on the boot screen.
After alot of hit and tries I used TWRP for Factory reset and WiPE DATA.
Since then I was totally lost in a boot loop.
I used ODIN with official ROM (downloaded through SAMMOBILE) for my variant and restored the boot but again my mobile went back to stock version.
Now the problem is that my phone gives me a message "FACTORY MODE IS ON ........................................."
Now my WiFi turns OFF automatically and everytime I bootup my mobile I have to enter passcodes for WiFi every single time.
I have again got it into Developer Mode and got the root access as well but when I check the EFS folder using TWRP, ROOT EXPLORER or any other software which has access to root files I can see that EFS folder is empty.
I even tried restoring the backup through TWRP (first time complete and 2nd time only EFS folder). It shows success but still EFS folder is empty.
Now I need support if anyone can either help me with the EFS file or help me restore the EFS file that I have available through TWRP backup.
In desperate need of help because I have tried every method I can find on this forum or after google results but none is working...
Any support to help it work will be very helpful and save me from losing my only source of mobile communication.
ThankS!!!
