[Help] Stuck Boot Logo

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?

You are wrong. If he doesn't tick repartition and doesn't use pit file. His mobile will not be correctly partitioned according to partition table.
Help me too
Help me out.. My friend's ace with this same model too is suffering from the same problem. I was the one who tried to wake it up after the hard brick. I repartitioned and flashed the stock firmware through odin, flash was successful. But the error mounting data appears and the device stucks on bootloop. Also i saw something like unable to move data_recovery_log.
I usually come across mount data errors after flashing stock firmwares in my Galaxy Y duos (s6102) but for us it is known that it would be resolved with a stock data wipe.But that too failed in this case. I am not familiar to the repartitioning things..

Phone stuck at logo screen.

Hello,
As the title mentions my phone is stuck at the logo screen (the one that says Samsung). Because of this I'm pretty sure it soft bricked (caused by me playing with link2sd) and thus will need a fix. The phone is a Australian Virgin Phone 4G Samsung galaxy s3 and so I tired using Odin and a 4.1.1 Optus MD5 to restore it. However, this has not worked and so I will be needing any other advice or ideas you have.
Please note: I can get into Download mode and recovery mode easily and when I do go into recovery mode it says failed to mount /efs (invalid argument)

I have the EFS folder on nandroid. However, when I used Odin to restore my phone it deleted CMW. Is there anyway to install the nandroid or get the file off nandroid or put CMW back on the phone to install nandroid and would this work?
hi
try this link
http://forum.xda-developers.com/showthread.php?p=41593409#post41593409
Reinstall CWM Recovery using odin (donwload mode off course). Ensure to install the same version you used in your nandroid backup for compatability.

[SOLVED] GT-I9300 Brick? Stuck on Samsung First logo

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.

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 ;

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.

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

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 )

If your device cannot turn on and you have flashed a PIT file then you need a service repair or new motherboard .
if you cannot turn on your phone,you can try to flash a stock rom in download mode,
if more worse,such as pc no respond in download mode or cannot turn phone into download mode,you may need a physical repair.
Thread closed, please read and/or post IMEI or EFS related material in the dedicated FAQ thread for this.
Thanks
