HELP!!!
After i tried using App2sd on my rooted S3 I9300 (Intl version), my phne went into a boot loop, and apparently i tried fixing it by installing a new rom..now, here comes the real problem..I installed a wrong ROM, it seems (although the rom is for i9300, it is for a different region)..
So after installing this Rom using odin, i get the message "e: failed to mount efs folder"..
Now im lost, especially because i have no backup of any kind...Is my efs folder corrupted??? and the phone still wont go past the samsung logo..only hope i have is that i can enter into recovery mode
Any suggestions ??? Please..anything...

Unless you have an efs backup, or flashing an EMG modem enables your efs partition to be read again, then you are basically screwed and need a service centre.
Hei,
I was running 4.3.1 Dirty Unicorns and wanted to flash Smartdroid.
So, flashed Devil recovery and tried to flash the ROM.
It gave me message that there's an error in the zip file.
I was just playing with the options available in the recovery and selected some option, which I don't remember now.
After that, the went into bootloop. "Samsung Galaxy S3 I9300" appears on the screen and the phone reboots again and again.
This loop continued.
The phone could be put in Download mode.
Then, I flashed CWM 6.0.4.4 and flashed 4.1.2, which I downloaded some time back.
It went on well. I could boot the phone and had set it up.
However, I couldn't connect to network.
The IMEI was some default one.
Rooted the phone and tried to restore the backup of efs folder using HC-Ktool.
After restore, when I booted the phone, it didn't boot.
"Samsung Galaxy S3 I9300" appears on the screen and the phone reboots again and again.
I tried flashing the ROM again, CWM again etc etc.
Nothing worked.
In one occasion, after installing CWM 6.0.4.4, I restored from NANDROID backup. Restore was successful.
But, it wouldn't boot.
Same "Samsung Galaxy S3" appears on the screen and the phone reboots again and again.
Once, I flashed Dirty Unicorns ROM from zip via CWM. Still the same.
What is happening and how to solve it?
Any help is greatly appreciated.

Wipe Data/Factory Reset -> Download mode
Flash latest Android 4.3 from Sammy through Odin, preferably XXUGMK6 or newer.
Hei,
This worked!!!
Thanks.
Why flashing 4.1.2, Dirty Unicorns didn't work and this one worked?
If you can explain, that will be helpful to all.
Now, though the phone is booting, the efs folder is corrupted.
IMEI number is not what it should be.
I have a backup of the efs folder taken using HC-Ktool long back.
So, the ROM on which efs folder was backedup will be different that the ROM I have now. (Does it make any difference?)
Can I just root and restore that efs folder using HC-Ktool?
Thanks for the help!!
Regards,
Babloo
Edit:
If I flash CWM Recovery 6.0.4.4 and restore the NANDROID backup that I took before I started screwing my mobile, will everything be fine?
Sounds like you tried to flash a corrupt file, always check the md5 before you flash.
EFS is totally separate to the rom, format the partition, restore your backup then factory reset should return your imei on the current rom.
Nandroid will not fix the efs, unless you used a custom backup process that included the partition -the default settings would not do this.
Hei,
"format the partition, restore your backup"
For this, can I just root the phone and use Ktool to restore backup?
If you suggest any other procedure, pls give me more info.

Hei,
After the previous post, I could restore my phone from NANDROID backup that I took yesterday, before the whole mess.
After that, I tried to restore the efs folder using HC-Ktool from efs.img.
It gives the message that restore is completed.
But, after reboot, the IMEI remains the same wrong one (the generic 004999...)
The size of efs.img is 20.48 MB.
I tried to restore using the terminal method.
With the command "unmount /efs" I get error message "sh: unmount: not found"
How can I restore the efs and get back my IMEI?
When I tried to "open" the img file in Windows, it couldn't open. It says that the file is corrupted.
Could it have been really corrupted or it is just that Windows is unable to open it?
I restored the efs using the same backup file.
Why is it not working now?

You are trying to skip essential stages and hurry to finish, but your partition is still corrupt -you can't restore anything to a corrupt partition.
Search and read someone who has succeeded doing the same thing, follow their guide exactly.

I have been searching for a proper procedure to format the efs partition since your post.
Whatever I found didn't work for me.
Can you please point me to any post that you know?

Guys,
Any ideas?

I have a gt-i9300 with ap I9300BUALE6 cp unknown csc I9300VFGALE6 on android 4.0.4 problem was that i wanted to reflash the software because my sim card/wifi didnt work (doesnt see any wifi networks) also wont see any sd card and baseband was unknown.
Downloaded from sammobile latest firmware for vodafone germany I9300XXUGNH4_I9300VFGGNH2_VD2.zip and i flashed with odin v3.12.7 hit AP box and extracted the firmware zip file, selected the md5 and it flashed succesfully but the phone now is unable to enter on android, im stuck with samsung logo and blue led.
What can i do? I also reflashed again and entered android system recovery <3e> hit wipde data/factory reset and also wipe cache partition but i am still in bootloop. There is an e:failed to mount /efs (invalid argument) error, i had this also with 4.0.4.
Is there any way i can fix this? did i flash the wrong rom? what can i do to bring it to life?
I think the EFS folder is where the imei and MAC address information is located. Do you have a backup of this folder? If not, you may have to have the phone reflashed at a repair shop that can also restore the imei.
i dont have a backup of efs folder.
cant i reflash it without going to a repair shop?
@Zedgor: since you flashed firmware for Germany, this repair-tool might help, at least to get a booting system. You loose your data by repartition and cannot go back to outdated 4.0 afterwards, due to 'new' bootloader.
my phone is galaxy s9+ korean, G965N.
i installed twrp but i got this error message("failed to mount '/preload' (invalid argument)") when i install something or format system or whatever i do.
i know there is no wipe option for preload partiton(this is main problem of this situation).
i searched solution and found two method
one is flashing cwm recovery -> there is no cwm tar file for my phone so failed.
two is flashing new original rom -> i don't know how can i do it. i know just odin flashing method. i can't do other method(adb or fastboot) because my computer can't recognize my phone with that two method.
is there anyone that know solution of this problem?

i can't boot normally and i can't even see samsung logo but i can boot normally after flashing pure android 10 firmware using odin. after pure firmware install a problem happens when i install twrp and dm-verity that is flashed to boot partition(kernel partition).
my phone is SM-G965N(galaxy s9+ korea version).
