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?

Hi everyone,
I don't like to post here, as I prefer to find the thinks by my self,

I was running foxhound + boeflla kernel witch I read that support swap, and I'm trying to get this work,
i download the app called : swapper 2 or something like that, I ticked some options on the app, and PUF my phone restart and stick at bootlogo, I can enter in CWM and Download mod,
1- I tried to flash the combo that contain all the files ( mix.pit, bootimage, rom, csc and modem ), and tick re-partition, but still at bootlogo,
2- my s3 go until the samsung bootlogo ( pass the samsung galaxy s3 gt-I9300 ) but stick there, i've tryed a lot of things, even in CWM, like do a full wipe and install other rom, or make and nandroid recovery, but nothing happened
3- when i try to do a full wipe on CWM I get a mensage E: /data partition can't mount, if I try to mount /sdcard the CWM retorns the same mensage, somethimes it shows E: failed to mount /efs (invalid argument)
so, my phone is bricked ?, the only way is to do a unbrick JTAG ?
:crying:
Could someone please help-me ? =/
if someone have tha correct pit file for international SGS3 16 gb, i found a lot of files but none have a functional link,
sorry for my bad english if I have a mistake .....
Re: [HELP] Please help with: Can't mount /data and internal storage
Why would you mess with your phone if you have no idea what you're doing?
restore your efs for starters. google how
hi,
my internal sd card is currupted, i can acces the others partitions like /system etc, but i cant acces the /data and /efs,
my phone stick on bootloop, why can I restore the efs partition ?, I have tried to restore to stock in Odin, they show pass but the phone stick on boot ( samsung logo ).
if don't want to help please dont be rudge, i'm not a noob, and not just because I'm new I do not know what I'm doing...
any way, is there a chance to flash a rom, and start it in external storage ? i see that if i change some parts of a kernel and repack it i can do this.......
i was searching a lot on google, and nothing can help me, that's why i post here !
please someone that are expert, help me !
U have deleted EFS folder ( i had the same problem this weekend, send my s3 to servise.) Try installing (first that u had) stock rom 4.0.4 and install whith odin. If u have your efs folder backedup is the best solution.
Sent from my GT-I9300 using xda app-developers app
However if you don't have your /efs folder then... BRICK. Your last choice is probably some restore options like repartitioning of /sdcard (option from CWM/PhilZ) but if that doesn't help then game over.

You mean that flash android 4.0.4 can make something diferent than the 4.1.2 ?
i have a backup of my efs partition, but the problem is that i can't boot my phone, only recovery and download, and i have tried to partition my internal sd with CWM and with PIT file on odin, but nothing happen =/
I think that the only way is to buy an JTAG kit and make a unbrick process, someone have another idea to solve my problem ? my phone is under warranty but my flash counter show 6, is there a way to reset the flash counter to 0 using Odin or CWM ???
this will be a very hopefull information, please if someone know how to reset the flash counter usin only Odin or CWM tell me !!!

Same here, still didn't found how to fix it.. I guess our motherboard just died..
Howewer I have a solution that "almost" worked for me.
Get a stock firmware in odin and turn on Nand erase and T-flash
When it's done phone reboots and you'll see just "Downloading..." mode when you turn it on.
Then got to Kies and Select firmware recovery...
Enter s/n and model name and wait for the flash to complete.
With it , I got past boot logo and actually booted into android but the phone crashed because I guess I have a memory issue..
Well , gl. If you don't find anything else helpful , try going with this method..
there is soulution for this look in cwm-mount/unmount-format data,sd,.... last option and after reinstall sys using odin to oryginal android or some custoom room if rooted (offcourse):good: i just did like this and it workd !! boot screen some seconds and please enter pin code

This actually worked! Thank you for posting this. That option in CWM was the only one that actually recognized the /data and removed the corrupted image/preloader I flashed previously using the S5 SIII rom.:victory:

I had this same issue, but I solved it now running DeoDex 8.1 with Magisk and TWRP.
Basically, this is a brick, but Knox doesn't let you recover from it the normal way. As long as you can boot into TWRP you should be good. Usually caused by safety net issues.
Access TWRP. Select Wipe and then press format data. Once this is done you should be able to boot to your carrier logo or phone logo and be stuck.
Basically what's happening is your phone (Knox) is preventing you from rooting. This is a method Samsung uses to validate that damage to a phone was from Custom Rom, Custom Recovery, Root, etc. Samsung doesn't have permission to void your warranty without proof that the brick was directly from the mod/hack.
In order to bypass this you need to trick the phone to think you undid it, even though you didn't. First off, boot into Odin. It cannot be done through recovery, as that skips a step. Next you'll want to press Volume Down (Cancel (Reboots Phone)). You will be on the logo for a while, than you should see a loading symbol. Once booted into android, you'll want to boot back into recovery.
From here, you want to do I standard factory reset. Once that is done, reboot. Once Android is up and running boot back into recovery.
Select Backup and make sure only the standard three options are selected. Press backup.
Go ahead and install your root, and if something happens press Restore and select your backup.

Can you please describe in a little more detail how you managed to trick the Knox system? I have an I9305 where neither internal och external storage is possible to mount. I can boot TWRP but every try to wipe or format the system is failing because one cannot mount the storage. I also can put the phone in download mode and connect to Odin, but the same happens, that every operation fails... probably because the internal storage cannot be mounted. In download mode I can see that the Knox flag is activated, and I hope that your trick can help to get access to the internal storage again. Can you please tell step by step how you did it? What does "boot into Odin" mean? Can it be done differently than starting Odin and connect the phone in Download mode?

Sorry if I was confusing.
Basically what I meant was boot up the phone into Download mode, and once at the screen instead of pressing volume up, press volume down, and you shouldn't see the original error anymore.

Thanks for the clarification. I have now tried that, but unfortunately the phone is still stuck on the first boot screen, and TWRP is not able to mount any storage.

When you say any storage, do you mean it is all unmountable, or do you mean the certain ones are unmountable, and the rest are listed as 0b?
Anyways, there are many more options, the only problem is most of them do in fact require you to lose your data. Hopefully you allowed Google to automatically back up your Android device, and if so you won't lose any data. Check out this thread, but it is designed for the J7, so when you download something, make sure it is designed for the Samsung Galaxy S III 19300/19305.

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.
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..

restore you efs backup. if you didn't make one - replace the motherboard

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?)...
@dhirend_6d
I'll check on that mate thanks..

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)

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.

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?

SOLVED!
Hi @IRPnet!
I found the solution yesterday! Is neccesary to have a EFS backup.
Just restore the EFS folder using the Philz Touch:
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 Backup EFS > Start Custom backup Job> Restore from External SD CARD> Select your backup file and restore
4. Reboot device
Doing this make my phone work again!
Greetings
same problem here, but i don't have a efs backup. what can i do?
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 )
Hello guys,
yesterday i tried to install a rom, i accidentally formatted everything (including internal storage) and when i tried to reboot; it didn't. I just tried to install a stock rom with SM-G925F BUT not corresponding country of mine (on kies3 mine has AFG in paranthesis .wtf. ?), then i downloaded firmware from sammobile which has name;
G925FXXU2BOGB_G925FOJV2BOG8_G925FXXU2BOGE_HOME.tar
I kept flashing this rom and twrp recovery to reach into adb mode to flash any rom to just save my ass from losing efs/imei even if i did. But it doesnt.
To tell the problem in a way more understandable way;
The device cant boot itself.
I cant reach it from mtp or adb.
I can only get in download mode. whatever i do flash doesnt work.
it also says that cant mount efs (this part is im scared of.)
EDIT: I dont have any backup of efs.
The phone was 5.1.1 also tried to downgrade.
also tried flashing g925f pit file
EDIT2: Bought otg and flashed another rom but still the same issue... Please help me guys...
EDIT3: The Required download links will be on the top of the OP
Thanks for answers!
Did you try to flash stock firmware with Odin ?

yes I did, I also tried different kinds of roms for g925f to just make sure. I also fetched the rom that smartswitch wanted to flash; which means I have already tried all the methods from the choices of a noob like me ( if i get to this point this means im noob ) will ever know.
I will appreciate a help to unbrick my phone so i can enjoy my beer with him

Hi
i had a big problem with anability to mount any partitions through the flashed TWRP recovery i had on the S6 edge, lucky me i had a full backup including the EFS partition, and could either boot into download mode or TWRP, but as you unable to flash anything properly.
Odin, flash multiple roms...
Samsung Smart Switch and kies, emergency recovery providing the model + serial number failed
To top it all, i had reactivation locked enabled....
Now for the EFS, if you are able to get TWRP installed and running from it mount a USB OTG and backup the EFS partition
Here are links for Kernel by Alex-V
https://www.androidfilehost.com/?fid=24052804347765201
TWRP from Team Win
https://dl.twrp.me/zeroflte/
You would need to root after that, but thats not your problem at the moment, and for me the kernel is needed or else i will stay stuck and can only go into downoad mode
When almost everything for me was at the point i had hard bricked my phone i fixed it with Odin in the end
Firmware SM-G925F / G925FXXU2COH2
http://samsung-firmware.org/download/Galaxy S6 edge/31bd/XEU/G925FXXU2COH2/G925FOXA2COH2/
At first this also did not work, but i kept looking and was thinking if it cant mount anything, partitions might and probably were corrupted
PIT files that can be used, normal and ones with different HIDDEN sizes
http://forum.xda-developers.com/gal...925-pit-files-multi-thread-download-t3171636/
For me the first standard one failed at the hidden.img everytime until i used the last one which was
ZEROLTE_EUR_OPEN_HIDDEN300M.pit
Flashed completed all the way and rebooted on its way to the android normal post flash install process
During the process it first complained about DATA partition being corrupted and needing to flush it, then rebbotted to complain about internal storage needing to also be flushed.
On the final reboot, it went all the way in to the normal setup, accounts etc.
At this point i was again stock and 100% fixed minus the EFS partition
At this point rebboted into download mode, flashed TWRP
Remember to copy the modded Alex-V kernel and the super-su zip files if you want to avoid sweating some more!!
I plugged my USB OTG with my full TWRP nandroid backup and restored it all, EFS included, at this point the state of the S6 was again 100% operational
Hope this helps you and others.
PS. Verify before flashing anything that those can be used on your phone or if not find the equivalent files you need to do so.
The culprit that caused the problem to start with was stickmount app by chainfire who makes Super-SU!!
What happened is i instaled it, then it told me it needed to copy some extra files, at that point during the copy, the S6 rebooted and was stuck in an endless bootloop
That happened with the abobe firmware linked above, using that kernel and that version of TWRP flashed on the phone with Super-SU 2.46 installed
Even going with Aroma Explorer and deleting everything i could find on the phone related to stickmount did not fix the problem

will try this mate if it works for me too, we should open a new post or update this one to inform people
Update: Nothing worked until now. Does flashing a rom from an usb-otg or internal storage differ? Also I can't connect to computer via MTP or ADB... Need serious help guys.

1) efs partition is deleted
2) emmc files are deleted
if anyone knows how to fix emmc please write here efs is easy to deal with....

it doesnt flash because eMMC files "mmcblk0" are wiped.. Maybe a jtag issue. Is it possible to repair it without jtag?
If adb cannot detect it..i guess jtag is the only hope
