10 hours after i tried using the swapper 2...my galaxy s3 GT-I9300 rebooted suddenly and got stuck in the galaxy s3 logo. I was rooted and had sotmax v14 running on it. I flashed it several times with that ROM and also cm 10.1 from the sd card. Then i flashed it with a stock ROM using odin. I had access to download mode and recovery mode. In the stock recovery mode it showed something like "E:/eror mounting efs((invalid arguement)).
I have very little knowledge about flashing and i do not even know what EFS is and thus i dont remember of taking a backup of that efs. I flashed it with CF root to access CWM recovery. Now in CWM recovery when i chose sd car it says
"E:cant mount sd card" and when i tried to mount efs it displayed "error mounting efs".
I have been trying hard for 2 days with little food. Any help would be highly appreciated. Help me. What should i do now?? Iam stuck on the galaxy s3 logo no matter what i do...i tried everything factory reset wipe data cache etc etc. please help!!!!
please help i have the same problem when i try to restore my efs folder
i have access to download mode and costum recovery but the phone is all time in bootloop in the logo of samsung galaxy s3 gt i9300
just restore the efs backup you've made. if you didn't, try restoring any nandroid backups, maybe they have efs included. if that doesn't work, try looking in the sdcard for some files that have "efs" in the name, some kernels back it up automatically. use adb to view the files (Google it). if that doesn't work, try flashing a stock rom and factory resetting from recovery.
and that is absolutely everything you can do.

The main problem is I am not able to access the sdcard as it says sdcard cannot be mounted. I remember to have made backups with ROM manager but i dont have access to it. I had ICS 4.04 running on it when i purchased the phone. I tried flashing the phone with two compatible ROMs from Sammobile.com which are jellybean ROMs and factory resetting it, but that did not help too. Are those the stock ROM for the galaxy S3 or should I flash it with ICS 4.04??? Please help me. Thanks in advance!!!!

I have got the exact same problem with my S3 GT-I9300, phone bootloop, error mounting efs after flashing omega rom aokp. Can you please explain in detail
which stock rom 4.0.4 you used ?
which odin version you used because I am finding that it is greyed out on every flashing of rom that I did ?
any other detail you think I should know coz I am quite new to this flashing stuff.
Thanks

Hello, I got an SGS3 i9300 with stock rom now, and it is stuck at boot logo of Siyah Kernel, When i enter into Recovery mode, i try to mount EFS and get this error "Error Mounting /efs!" is there a way to make it work? Because i try many roms, i follow a guide to install a Stock ROM that i have now the latest for my country (Spain) without luck, is there a solution? Thank you.
Hi there,
just a stock firmware via ODIN.
you can find download here:
http://samsung-updates.com
I already install a Stock rom, i got a EFS Backup, but i can't put it, because i can't go into the phone it don't boot, it stop at Siyah Kernel boot logo.. And i can't mount EFS folder cuz of that..
Try a factory reset/data wipe from the recovery.

I don't get it. Maybe this is a new system or something, but on i9100 we can at least boot into the system and all. Its just that we get no signals, but everything else works fine? Why isn't your phone booting into the OS?

the EFS Folder, i get into it via Root Explorer, and the folder is empty, the phone stuck at boot logo, when i get into recovery mode appear an error that says "Error to mount /efs" i got a EFS Backup and i push it via ADB whole folder, now i got an error on recovery "E:error to mount /efs (The file is too large) and i can't even delete now with EFS Pro, the program shutdown, i got the riff box, im new with it, is quite easy to use it with "Jtag adapters" but with the small chip that came with it, im completly new, to solder the right cables to the motherboard, i know if i can do that, i can resurrect the phone, and repair the IMEI directly, im trying to get info about to know how to solder the cables.. that's why i was looking to another options to make it boot again..:crying:

Hi there guys!
I was restoring my EFS folder with Ktool in Omega v48 but the phone Freeze so i had to remove battery. After that the rom is not botting up and is stuck on animation logo. So i decide to flash my GT-I9300 back to stock trough ODIN, so far no problem, i entered download mode and flash, but when the phone is rebooted i got stuck @ galaxy s3 logo (not the animation), so I manage to install CWM and try to flash a custom ROM but this time the device is stuck on animation boot. I did a full wipe several times but nothing is happening. I can enter download mode and flash with odin but the result is the same, don´t pass the samung logo on stock rom. I got Phliz TOUCH CWM v5 installed and fully working.
The stock i already try: I9300UBELL6_I9300MVLELL1_MVL / I9300UBELL6_I9300DGTEMA1_DGT
Custom ROMS: OMEGA ROM, (i tried with paranoid but is stuck in the first logo again)
The output in the download mode is:
ODIN MODE
PRODUCT NAME : GT-I9300
CUSTOM BINARY DOWNLOAD: YES (6 counts)
CURRENT BINARY: CUSTOM
CURRENT STATUS: CUSTOM
Any idea what might be the issue?
FOUND THE SOLUTION!
I found the solution yesterday! Is neccesary to have a previous and fully working EFS backup.
Just restore the EFS folder using the Philz Touch,(if you dont have it yet go and flash Phliz Touch CWM v5!):
1. Create the folder Clockwordmod>backup/.efs_backup/ folder in external sd
2. Copy the backup of the EFS folder, can be a img or tar file
2. Reboot into Philz Touch CWM
3. Go back to Philz Setting> Custom Backup and Restore> Custom Restore Job> Select only "Restore EFS" > Start Custom Restore Job> Restore from External SD CARD> Select your backup file and restore
4. Reboot device
If you get a error about the directory: Create a backup job, delete the new files and copy the EFS Backup (The fully working) in the directory that has been created with the new custom job.
Doing this make my phone work again!

I already read the BASICS, the problem is that the device is not booting.
To be clear, your phone is booting, its the ROM that isn't
If you are getting stuck at the animation logo, that would suggest one of two things.
1) Its possible your EFS partition is corrupt. A warning message should come up as it tries to boot. Do you have a working backup?
In my experience, an uncompressed backup is the only saviour.
2) The ROM you are flashing is not compatible with your phone (MODEM FIRMWARE CHANGED??)
Have you tried installing a stock firmware, even better, an original firmware (i.e. the one it came with)?
Is there a reason you were trying to restore your EFS partition? Was it corrupt before you started flashing?
The answer to these questions is the difference between you getting a working phone and/or going to repair centre.

Yes, i have lose my IMEI a few weeks ago. Make IMEI repair with a box (very expensive by the way), when the phone arrived i have made a backup using efs pro and ktool, the installed ROM in the moment was stock I9300UBELL6_I9300DGTEMA1_DGT. Since that incident i always have to restore imei when i install a new room and always use the stock rom for restore the phone until now.
The download mode and CWM is fully working!!
Greetings.
I have the same problem. Same happened, wanted to restore EFS with Ktool and soft bricked. I found out that the only thing i can flash is the stock ics 4.0.4 XXBLFB and when i do that i still don't have mobile network. Tried flashing stock firmwares / roms but everything else than already mentioned ics gives me bootloop/ freezes on boot. I've sent it to repair today but if you find something out please update us.
Cheers mate
Sure mate, i will try a emergency rescue via KIES and will update the post soon.
Well..I made a emergency recovery trough KIES. he flash the original rom but is stuck on the Samsung boot animation, i rooted and install CWM trough ODIN make a wipe data/cache/dalvik and nothing happen is still stuck on the boot animation.
I will download the original firmware from sammobile i see if i can flash trough ODIN.
Any other recomendations?
I can only comment on my own experiences, but here goes.
I tried to flash an Omega ROM and lost my IMEI number and serial.
Fortunately I had several backups of my EFS partition.
I restored it. I found that every time I rebooted the IMEI was erased again.
I then saw a post about about setting permissions for files in EFS. I set and since no problems!
My EFS backup was made through TWRP recovery.
To set permissions I used a terminal app, but it can also be done by ADB.
Check the flashing basics post/sticky and all you need is in there.
The important thing is that you have an EFS backup.
Sent from my GT-I9300
Thank @IRPnet
But the problem i got now is the not booting ROM, i already install the original rom trough emergency recovery with KIES; download the same rom trough sammobile and flash via ODIN and the result is the same, the device is stuck on samsung boot animation it won´t start.
PLease somebody can help with this? I already have made a wipe on the device several times and nothing is happening
Ok, I found the a comment I have used previously.
So, assuming you have a backup EFS, restore it. (If you don't have backup this is not gonna work for you)

Open terminal emulator and type as ;

rm /efs/FactoryApp/keystr

echo -n ON >> /efs/FactoryApp/keystr
echo -n ON >> /efs/FactoryApp/factorymode
chown 1000.1000 /efs/FactoryApp/keystr
chown 1000.1000 /efs/FactoryApp/factorymode
chmod 0744 /efs/FactoryApp/keystr
chmod 0744 /efs/FactoryApp/factorymode
reboot
You now should not see the that message anymore. Its because of an EFS corruption. ( Thanks to yesilcin*com (sawgent) ) for exact solution.
Hope it helps!!!

This will ensure that your EFS partition "sticks". Otherwise, when you reboot your phone you will have to restore EFS again!
Hope this helps.

Without a backup EFS you cannot do anything. It will be a shop repair.

use following method for those who do not have efs back up :
1. flash full stock rom
2. it will be stuck at samsung shining animation.
3. pull out the battery
4. put back the battery and boot into stock recovery by pressing vol up+ home key + power key
5. wipe data and cache.
6. reboot , and your s3 will be boot up sucessfully ( if you are lucky enough like me )
