History:
Well not really sure about what happen to the phone but when it was handed to me it was already stuck on boot logo.
I can go into recovery mode but it always say E: failed to mount /efs (invalid argument) which I reckon would be an empty efs folder since I handled some problem too before with same problem and they all got no files on efs folder.
Well what I already did was flashed it with 4 part files via Odin3 v3.07 from the rescue firmwares from here:
http://forum.xda-developers.com/showpost.php?p=30087735&postcount=6
Used XELLA and XXEMC2 with pit and it flashed all right but still stuck on boot logo
Question is, is the empty EFS causing the stuck on boot logo or some other issues like NAND corrupted/damaged already?
Or can I rebuild the EFS folder from other i9300 working EFS in the stuck on boot logo state?
Thanks in advance for the input..

Yeah seems like your /efs is wiped. Check out the discussion in the thread here.
@Glebun
Well I don't have the EFS backup as clearly stated on my first post and while replacing the motherboard is the quickest "fixed" possible, If I got lucky and I have one? But I am just wondering out of the blue if there's another workaround, I've went through a lot of threads here with same problem but unfortunately no concrete solution than send it in for replacement, anyway just trying out my luck on this thread.
Update:
Well there's a miracle happened,
I flashed it again with the XXEMC2 without the pit and now it went past to the boot logo but it just keeps on restarting now on the Samsung animation welcome screen (say a boot loop?)...

I'll check on that mate 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?

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)
Restore your backed up EFS folder .

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.
today my battery went down to zero and then my phone stuck on the menu screen.
i rebooted but then my phone got stucked on the samsung galaxy 3 logo.
i tryed to wipe files and catche but it didnt helped,
i tryed to install the ROM again but it didnt helped...
i can get to the recovery and download mode, but my phone still stuck on the stuped logo...
what to do?
sry if i have spelling mistakes...
You have corrupted one or more partitions, try a factory reset after flashing your custom rom again.
If that doesn't work then use Odin to flash a stock firmware, then factory reset.

Means you screwed the efs partition when flashing an incompatible modem with your efs version.
If you flashed a 4.1.2 firmware and got that error, try and flash a mg4 or above modem to see if it gets solved. Or flash a 4.3 firmware altogether.
Read rootSU post on efs, it's a must.
Of you ever backed up your efs or used twrp recovery to make a nandroid backup (which also backs up efs) you might get it back by restoring it.
Otherwise, a patched kernel, modem or ariza patch would be the last available choice before sending to repair.

I mean, go to the stickies in the general section and read. They're there for a reason, including steps before rooting, flashing, information on the efs partition, and pretty much everything else you could have done to avoid the situation you're facing right now.
my main problem is my EFS is totally corrupted. i have yellow writing on my ROM which i have read is permanent safe mode and that i need to restore my efs. Sadly i dont think i salvaged enough, i made a EFS backup yesterday (sort of) before i started fiddling around to try and unlock my phone. i have the .img file and .tar file on my PC but i have read you need a gz file?
When making the backup i was on custom 4.3 ROM and im now on stock 4.3 rooted.
UPDATED
i have attempted to restore my efs using a the utility here http://forum.xda-developers.com/galaxy-s3/general/tool-backup-restore-efs-imei-sgsiii-t1901098
however i get this pop up and when i reboot its just stuck on the blue Samsung logo and wont boot into the rom
http://gyazo.com/e0f93bc00b9355d7e58712f5bd162e53
History of my actions
1) had working rom perfect - made efs backup using galaxasim unlock
2) IMEI corrupt from an update
3) did super wipe on phone and installed stock rom using ODIN, after update phone just got stuck on samsung logo
4) flashed this file which got my rom working again but of course i had a corrupt IMEI https://www.youtube.com/watch?v=xJMJLdzHaAY
5) restored EFS and now phone wont get past samsung logo again (tried clearing cache and wipe data, I also get this error when doing a full wipe from phil CWM [formatting /sd-ext unknown volume for path [/sd-ext]
any help?

Already did that few times .
know this stuff, it's not my first time doing something like that .
but problem is that even flashing it with PIT file, it still goes to "android optimization" boot loop
that's why i need all 4 flash files , maybe that will help me?

have a look an that website. search for recovery firmware for your phone. it should give you the recovery 4 file firmware
http://d-h.st/mzeV
only found this , but i can't download it :|
Can anyone help me with downloading that file?
don't know what's wrong with dev-host , but can't download it .. tried 3-4 different pc/mobile and networks, with no luck
Finally fixed problem.
1)So to boot device you need custom kernel like Aroma for 925P
2) to get out of continuous restarts because of samsung security, you need to instal custom recovery TWRP and then from recovery, mount system and from apps delete every folder with Knox in name and also samsung dm folders.
That's how i got my device back in working condition. i can't remember exact folder names, but keep digging and delete everything related to knox and dm
i've even got my imei number back, so seems like efs wasn't damaged "too much" and only samsung security apps messed them up or something like that.
Anyway my phone is working now , so if you will be in same situation you can use this as tutorial
And no Z3x and similar boxes were not able to fix this, two local guys tried with z3x and similar tools with no success
