[Q] Failed to mount /efs (Invalide argument) and not Start - Galaxy Note 10.1 Q&A, Help & Troubleshooting

Hi
My N8000 not start. ODIN flash well (no errors) but Rom not start from logo.
I flash a Custom Recovery on Odin I made full wipes and install or restore Roms, but they not start.
After Odin if I go to Stock Recovery I have:
E: Failed to mount /efs (Invalid argument)
Applied the csc-code : unknown
Can't open /efs/log/boot_cause.
On Custom Recovery can't mount /efs also.
May be I must flash a Pit File? But where is it?
Thank You

I have a backup but the Note not start. How can I restore it by Odin/Pc?
EDIT: I have efs backups format .tar.gz Can I flash this on Odin?

Must odin back to original ICS rom to work
Assuming you have CWM installed on device and have androidsdk store on computer C: drive
device must be rooted
1..Plug Device to Computer.. Reboot Device in CWM recovery/ mount storage/ mount system
2 on computer Shift+Ctrl +right click to open command window
command window type
cd c:/androidsdk/tools
adb shell
su
mke2fs /dev/block/mmcblk0p3 ( skip to next step if fail)
mount -w -t ext4 /dev/block/mmcblk0p3
reboot
this will create a generic EFS files on device
when you reboot you will see your screen with a yellow text..now time to get rid of it
root explorer/efs and delete factorymode(OFF) and replace with factorymode(ON)
reboot in recovery wipedata factory reset...done
factorymode
Now you can back up your efs.tar(for 8000 user only)
Reboot and everthing should be back to normal

How i made my 8000 work again...
Hello everyone,
i hope i canhelp. I also installed 5.0 Collective and everything worked....until the first reboot. It did not start again so i installed ICS from samfirmware and had that efs-problem and yellow text. (using TWRP 2.4.4)
I first rooted the device installed busybox (make sure to open and let install busybox)
i also installed Android Terminal (both, busybox and android from google play)
i had an efs-backup ((efs-18Marxxx.tar.gz) wich i extracted once on device then copied it to pc and extracted it again with 7zip.
So finally i had the folder again, i copied backto device extSdCard.
i opened android terminal and followed BaDas Steps (in collective thread...dont remember the post number just search pls.)
I started es file explorer gave it root in settings and copied the efs folder to / (root)
i set the rights for efs same as folder factory and renamed the file 000000000.something inside efs folder to Aaa000000000.something.
i am not sure if the last step is needed, but lately my device worksjust fine.
pls excuse any mistakes in text, if u have questions just shoot, good luck and dont worry as long as u can get into flashmode ur device can be fixed. peace
Robert

Will this method work to restore a Galaxy S3's efs files with the proper 4.0.4 image? Stuck in Factory mode and the efs folder is empty.

n8000 getting ready for v6 to flash...
hello,
will flash the collective v6 by badab!ng now, will report hopefully within the next hour.

Dear Sir,
I think my EFS is corrupted cuz when i go to service mode, i get something which reads SPEECHver: FR FR FR when I bought my phone in the usa from tomobile. Cannot read sim card. Its a note2, i don't even know how to view or where to view my efs but i am assuming it is efs corruption, imei shows up everything looks ok except not recognizing the sim. Restored and everything, will this bring me back to original efs if i install the original factory rom?
Actually how do i view my efs details cuz right now i cannot use my phone everything else looks fine except cannot read sim. Will your method work with on a tmobile t889?
Thanks.

I am having the same efs issue
HI,
I am having the same efs issue when doing a factory wipe. My Tmobile Galaxy Note 2 is stuck in a bootloop and I have flashed the current Samsung firmware from their firmware site and it changed nothing. After I flashed it and the bootloop started I booted into the stock recovery and did a factory reset. That is when I got "E: Failed to mount /efs (invalid argument). I think one problem is I am a noob, the other is I didn't get CWM installed on my phone prior to all this. I do believe it all stimmed from me downloading and running Swapper on my phone. Everything seemed fine with it until I ran that and rebooted. To make matters worse, I failed (again noob here) to back up anything. Is there any hope for my Note 2?

You do know that this is the Note 10.1 forum don't you?
What did you flash?

thanks god I see your solution but...if I didn't install CWM...and android sdk...is there any other way to save my phone? THANKS!!

Dunno if CWM is necessary, but Android SDK is. Besides, It is going to help you to diagnose and repair many other problems.

GT-n8010 (Wifi) Factory Mode

Hi,
Hope someone can figure this as its wrecking my brain.
I got an 8010 (wifi only version) a few days ago.
Did the clockwork and rooting and it was all working fine, until..
Booted it up this morning and it flashed a message 'Unfortunately, Factory Test has stopped. Factory Mode is ON!!' and gave me the 'calculator' program for putting in service codes.
I've checked the efs folder and its blank, no files. (I do not have a backup, yes I know I'm an idiot)
I've since tried flashing a number of roms, including stock. None of which have resolved the issue.
When using the stock recovery it gives me an error about being unable to mount /efs
From google it appears that the efs folder is to do with the imei and other areas. As mine is wifi only version should I even have this folder?
The note appears to work fine with the exception of having a lock screen, power off options etc.
thanks
BB
Have you tried to flash it over the PC with Odin and the Files from sammobile.com ??
Have you tried to repair the EFS with this Tool: http://forum.xda-developers.com/showthread.php?t=1308546 ?

Hi,
I have tried with the N8010XWALG4_N8010XSAALG3_XSA from sammobile but am currently running the N8010-XXALH2-XAALH2-DBT-deodexed
Strangely enough I have just tried to connect with Kies, and it wont connect gives an error of 'No Sim Card inserted unable to continue communication'
I'm wondering if I've somehow confused my device into think its a 8000, when it is in fact an 8010.
I've tried the EFS Repair, it states that Locate /efs partition failed and can't locate any backups ;-((
I've just tried reflashing a stock rom via odin, selecting the re-partition and format efs section (got nothing to lose at this stage I guess)
I've also removed clockwork mod and gone back to stock recovery, which reads E:failed to mount /efs (Invalid arument)
would anyone have the .pit file / bootloader files? or are they built into the the pda rom?
thanks
BB
Pit file
Further testing has shown that the /efs partition does not exist or has become corrupt.
Would anyone have / or could make a pit file for a 32gb gt-8010?
Failing that would anyone know the terminal commands and dev location for making the /efs partition (make2fs ??)
Did you fixed the issue?

it is just factorymode file set to on
use root enabled file manager and copy to /efs over writing current one. but it's just as easy or easer to just edit current file and change OFF to ON

[Q] Bricked Note. No Samsung Logo

hi all,
So, I've been a bit of a idiot.
In a nut shell I was trying to manually remove the flash count and followed the wrong tut.
I did dd if=/dev/zero of=/dev/block/mmcblk0 bs=1 count=1 seek=3145732 and now when i try to boot the note I dont get the Samsung logo splash screen, I get a screen full of static.
I can access the recovery partition, I can also access in download mode with odin.
If I try to flash the stock rom, it completes ok but doesn't auto restart and stays on the odin mode screen.
I do get E:\ unable to mount /efs when i wipe the cache's.
I have a 2nd note 10.1 (both n8010) so I'm hoping I can fix/copy/image from the 2nd working device.
Any ideas on how to fix? or is it now an expensive paper weight?
I have flashed the stock firmware and rom from samsung-mobile but no joy.
thanks,

You are in a tough situation my friend
I think as long as the recovery and odin work there is a chance...
can you give me the link to that tutorial .. I think i may help
Or do you remember where that sector was??
Anyways you may try to backup both devices EFS (backup that of the non working device in case you need it for anything) .... (But i think the EFSPro wont work) (you may do that using EFSpro or i think it may be done through the shell by "dd if=dev/block/mmcblk0p? of=/sdcard/efs.img" where "?" is the number of EFS partition you can know that from shell command mount "i think its mmcblk0p3") .... then restore the EFS of the working device to the non-working one (EFS pro or using "dd if=/sdcard/efs.img of=/dev/block/mmcblk0p?" "i think its mmcblk0p3")
I hope this would succeed although i red that it contains MAC address data which may prevent both devices connecting to same network
(N8010 has no connection to cellular networks so i think no problem)

(But i think the EFSPro wont work) (you may do that using EFSpro or i think it may be done through the shell by "dd if=dev/block/mmcblk0p? of=/sdcard/efs.img" where "?" is the number of EFS partition you can know that from shell command mount "i think its mmcblk0p3") .... then restore the EFS of the working device to the non-working one (EFS pro or using "dd if=/sdcard/efs.img of=/dev/block/mmcblk0p?" "i think its mmcblk0p3")
I hope this would succeed although i red that it contains MAC address data which may prevent both devices connecting to same network
(N8010 has no connection to cellular networks so i think no problem)

But before all these go to shell and try "dd if=/dev/block/mmcblk0p3 of=/sdcard/efs.img" and "tar -cvf /sdcard/EFS.tar /dev/block/mmcblk0p3"
if these commands succeed you would have a backup of old efs before changing any thing (keep it in a safe place)
Look you may try just backing up and then restoring the same EFS of the device
Try this first: use the tar command to copy the files of EFS "tar -cvf /sdcard/EFS.tar /dev/block/mmcblk0p3"
then do " mke2fs /dev/block/mmcblk0p3" the last thing is to restore the tar with "tar -xvzf /sdcard/EFS.tar -C /dev/block/mmcblk0p3"
I prefer you try what i said first as it's shorter and makes nearly the same thing except that it takes all files not just the nv_data.bin
You can then try that tutorial in the link i think it works and you can get the that file nv_data.bin from your other device or from the non-functioning one if you can extract it from the tar backup in the first step
Cheers for the replies guys.
I'll find the tut I followed and post a link.
I'll also look into the link and suggestions you've mentioned.
My main issue seems to be that I can't get a adb connection to the device as it won't boot.
Even with cwm 6.1 installed, I still can't connect. Bear in mind, I've flashed back to stock but not been able to boot it to put it into usb debugging mode. does this mean I'll never be able to get a shell open?
I have managed to create a efs.img from the working device but have no way to push to the broken one.
Any suggestions?
Thanks

You say that adb wont work even from CWM??
Try this and see if it works http://www.dominantwire.com/2012/11/how-to-solve-adb-device-not-found-error.html
yep, even when booted into cwm recovery i still can;t connect to adb
just downloading a custom rom now to see if it's the stock rom causing the issue.
although I am able to access adb in cmw recovery from the other working device, even with USB debugging turned off.
sadly that link is no good.
I'm able to connect to the working device on the same cwm recovery version, using the same cable, so setup and PC are ok.
I dont know if the roms are the same (maybe not) but I'll flash the broken one with a custom 'pre rooted' rom in case it helps.

Ok try another rom as i think roms have diferences in adb !!
if not working also and If you know you can safely flash a new recovery .. try TWRP it has an inbuilt shell .. the keyboard is not that good but you can try it better than nothing
ok so....
I've flashed an different custom rom via cwm install from ext_sdcard. After a reboot I now have the samsung logo back!!!!
It's hung on the samsung logo for a wile now, 5 minutes or so, but I'll let it sit there for a good 30 minutes to be sure.
I'll see what happens from this rom flash, but failing this I'll stick TRWP on and have a go with the inbuilt shell. even if i can mount ext sd I should be able to restore the block i over wrote.
getting closer!!!
thanks so far,

Good to hear .. i hope it finishes the problem .. but in case it fails before flashing TWRP try from adb .. adb kill-server then adb start-server and adb usb and see if it works
will do, thanks.
I've just noticed that the command i ran I outputted to mmcblk0 and your commands refer to mmcblk0p3.
Am i right in guessing the the 0 part lists the disk and the px part is referring to the partition on that disk (so to speak)?
so my original command which broke it basically wiped the internal storage? this would explain a lot about failed connections as well.

Did the device work or did you manage to get adb connection??
Anyways ... from what i read during searching is that if=/dev/zero and bs=1 count=1 seek=3145732 parts of your command writes zeros only to one byte, one time after seeking 3145732 blocks of the storage which seems to be in EFS partition which says cant mount ... So the commands i wrote are to take a backup of whatever files in there then format the drive and restore the files back to it ... after formating using mke2fs reboot the device before restore and see if it shows the cant mount message again
arh ok, that makes sense.
I've managed to tar the efs files form the working device.
I then opened the shell in twrp and did a mke2fs /dev/block/mmcblk0p3 which completed ok.
But when i try to tar -xvzf EFS.tar -C /dev/block/mmcblk0p3 (from the external sd dir, it tells me that the mmcblk0p3 isn;t a directory.
any ideas?
thanks again
how about doing a dd if=efs.img of=/dev/block/mmcblk0p3??
I got a efs.img from efs pro on the working device..

try remove -C from the command it's for directory my mistake
and you can also try dd with (if=/"path of extsd"/EFS.img) but try the tar first .... after that see if it tells you cant't mount EFS by opening mount and select EFS and see if it becomes with an 'x' then going to the upper right corner of the screen and pressing the icon beside back and home and see if it shows cant mount EFS
sorry, before you replied i went and did a dd if=efs.img of=/dev/block/mmcblk0p3
I then flashed the stock ROM and BOOM!! im in!!
YEAH BABY!!!
only issue now is that the boot loader isn't quite right.
1 - it doesn't show the 'Samsung Galaxy Note 10.1" splash screen
2 - instead of above I get a screen showing the last thing i was doing, ie, download mode, but with static across it.
any ideas on how to correct this?

Can you answer some questions??
what do you mean by you are in?? .. can you get to android or not yet?? ... what do you mean with getting download mode with static ??
would you try going to recovery and clear cache and dalvik cache to try??
sorry, by I'm in I mean that I can now boot to Android.
when i say download mode with static, image the download screen but fuzzy and punctuated with white nose.
I've done a cache format and a reset to factory but I still get the same issue.
Also, I'm still unable to get an adb connection to the device.
I have noticed that the serial number has now changed to the same as the working device but thats expected as we copied the efs contents from one to the other.
thanks for all your help. you saved my bacon

Is there a way to delete/uninstall an APK and its data from fastboot?

so i went into FKU franco kernel updater and changed my CPU max speed from 1500 back to the default but did not change my voltage settings back to default. now the device is softbrocked and just boots to the google nexus splash screen
I have tried flashing:
system.img
boot.img
bootloader.img
stock 4.4.4 kernel
yet regardless of flashing the above the device still is softbricked and wont get past the nexus google logo.
the only thing i have not flashed over is my user data and thats because i dont want to lose my pictures and video of my little boy that i didn't get to back up yet due to my dropbox just hitting its limit.
Im hoping I can remove the franco updater app and its user data and boot but maybe thats not possible?
Thanks for any and all help!

Do you have a custom recovery? If so, use adb while in recovery to pull your files. If not, then flash one then pull them.
Not sure why you mentioned "boot.img" then "stock 4.4.4 kernel", boot.img = the kernel lol
Don't know why your device won't boot even after flashing stock boot.img, but if you use TWRP you can use the file manager to delete the .apk/other files.

thanks, i deleted the franco files and still cant boot.
i want top pull files but it looks like I need ADB and currently i can only get into fastboot mode.
(i'm using wugfresh toolkit, i know some say manual is the way to go but right now this is what I have to go on and have had no issues thus far with it)
i was using the button pull files in the tool kit but its not detecting the device since im in fastboot mode.
i swear I did a factory reset before and my photos were still present but many articles online say in 4.4 that a factory reset will wipe your photos.

since i can not boot, i am forced to use TWRP recovery and then go ingo CMD shell and ADB there however when I do ADB Devices i get the serial number showing its connected but then it says RECOVERY at the end.. much lke when you are in fastboot it says FASTBOOT at the end of the device.
i tried doing a pull using this:
adb shell
mount data
exit
adb pull data/media/0 c:\MyBackup
but when I do ADB Shell, the command prompt says this
~ # ←[6n
if t that prompt i type mount data then I get this:

~ # ←[6n
im not sure how else to get to a working ADB to perform a proper pull if i cant boot into the device fully

It could say "device busy" if data is already mounted. Does twrp have a "mounts and storage" menu like CWM? Where you can mount data? If so, check if it is mounted there (would typicall say "unmount data" if it was mounted, otherwise it would say "mount data" if it is unbmounted)

and when I hit enter it just shows a list of ADB commands as if it didnt recognize anything yet when I do ADB DEVICES it shows the device and ID

If you're going to put spaces in your folder names, you'll have to enclose the entire path in "...
Example
adb pull data/media/0 "C:\Users\srobertson\Desktop\Nexus 5 7-15-2014 DCIM"
Best to avoid spaces though.
I'll put this in the guide, thanks.

I ended up taking the leap and performing a Factory reset from TWRP and when I logged back into the phone I saw all my media was still present Whew.
just for posterity I went ahead and tried your code in ADB to make sure the quotes worked and it did so thank you very much and i will keep those notes handy for next time.

[Q] Accidentally Wiped /system, Can't Flash ROM

I was going to install a superuser.zip file to root my M4 but when I went to wipe the /cache the /system get wiped as well. I can boot into either CWM or TWRP and have full fastboot/adb, but when I try to boot into Android it just brings me back to the bootloader. When I try to install a stock ROM it just says it's flashing it but hangs at a certain point, I even had it run overnight and it still didn't install. When I try to flash a custom ROM suh as Cyanogenmod it either completes the flashing in about 2 seconds or greets me with an error. RUU and FUU don't seem to work. I'm 100% out of ideas now, and I'm open to anything to try.

flash your ROM in recovery just like you would normally (select .zip from sdcard) and boot up
run rumrunner, it should work, giving you S-OFF which will let you flash absolutely anything. If it doesn't, let me know and I'll come up with a workaround.

Well first:
~ # ←[6nmount data
mount data
mount: mounting /dev/block/mmcblk0p37 on /data failed: Device or resource busy
But instead I just used a USB OTG and flash drive so no big deal
And then Magio popped up with its installer and I went through that and then hit "reboot" to be greeted with the bootloader, so I hit "reboot" in the bootloader, but it still brings me back to the bootloader immediately after a black screen, so I thought "Oops, needed to flash the boot.img", so boot.img was then flashed. Now the green HTC logo is sitting there and isn't doing anything, probably frozen.
Code:
mount: mounting /dev/block/mmcblk0p37 on /data failed: Device or resource busy
means /data is already mounted
I actually got it up and running from a nandroid restore, I tried it once before but the restore didnt finish so I thought it wouldnt work. Thanks for helping me out anyway though!

Stuck at YU logo

1) Accidentally wiped all data including Internal Storage
2) Twrp 3.0 is working, but can't able to install any rom, Getting E:failed to mount / cache (Invalid argument) etc etc..
3)Getting "NO OS Installed" message in TWRP &- Internal Storage size is 0 (TWRP)
4) Followed Steps to flash factory image (WINDOWS)
Download the factory image fastboot package
Extract the contents of the fastboot package into a folder.
Download this flashing tools package
Extract the contents of the flashing tools zip into the same folder
To make sure, check that system.img, boot.img etc files are in the same folder as flash-all.bat, fastboot.exe etc
Connect your phone in fastboot mode, steps for which are : -
a. Power off your phone
b. Press and hold the Volume Up key
c. With the Volume Up key, connect the phone to your PC/Laptop with USB cable
d. You can let go off the Volume Up key when Fastboot Mode is displayed on the screen
Run flash-all.bat by double clicking on it.
A command window will open and flashing procedure will start
DO NOT disconnect the device during flashing procedure
The command window will close after the flashing process is over.
Disconnect the USB cable, and boot the phone normally by long pressing the Power button
But getting this error while flashing: http://imgur.com/g3NozUJ

Yuphoria stuck at YU Logo.
I had got notification for the OTA Cyanogen 12.1 Update and I had updated it. But even after reboot, the same 12.1 Update-notification would still appear again.
Later, I switched off Yuphoria to take out the External-SD-Card for data-transfer. Then when I switched on the Yuphoria, this Yu-Logo Boot-Loop Problem has started.
Now, My Yuphoria is Stuck at Yu-Logo on boot... and showing 'cannot mount partitions' errors when I boot custom-recovery twrp.
I have unlocked the bootloader.

My friend is an embedded service engineer. He is saying its just a soft brick and the device is perfectly working. Those knowledgeless idiots dont want to find solution for this, the simply trying to change the board. Friends the problem we have is 100% a software issue, pls dont fall in their trap............
Same issue
Guys anyone got the solution ? Please help ...
Anybody got solutions, please respond
Same here
I tried everything but nothing seems to work. Someone help....
Seems to be Soft-Brick Software issue....
TWRP Recovery is not able to mount the /system , /cache and /data partitions...
but inside TWRP Recovery FileManager , we can open and browse all partiton files and system folders/files in /dev directory....
Also the TWRP Terminal shell can be used to run e2fsck and mke2fs commands...
So I think the /system, /cache and /data , and other corrupted android partitions like /misc can be repaired and mounted again, using the right steps and procedures....
Then I believe TWRP Recovery will mount partitons again and work, and we will be able to install/flash new ROM... Phone will boot into OS again...
We need Somebody with enough technical know-how to run Terminal Shell commands and repair corrupted android partitions.
Please if someone can help, would be greatful...
I used my Yuphoria for 10 months... now lying useless for one year...

Same problem here !!
Tried to flash the ROM with QFIL but the port is not detected by the software.
Also tried with fastboot.exe method still the same sometimes it says write failed for Size too large of system.img and if I change the default size limit (with -S option) it says "Error : Write failed"
