[Q] EFS issue GT-N7105 please help - Galaxy Note II Q&A, Help & Troubleshooting

Hi all,
I have a Note 2 GT-N7105 which has always ran stock firmware and never rooted.
The phone gets stuck on the Samsung logo and won't boot any further. When I get it into the Andriod diagnostic mode (Not sure what it is called) I get the following EFS error;
E:failed to mount /efs (Invalid argument)
E:failed to mount /efs (Invalid argument)
I have flashed the phone using Kies which hasn't worked. I have also downloaded Odin and used that to flash the phone with a stock 4.3 image using a PIT file and repartitioned the phone with still no luck. I don't have a backup of the EFS folder. How can I remount/ repair the EFS folder?
I have connected the phone using ABD but I'm not sure how to enter commands or even if it will help.

We both are having the issue here. Though, I'm on GT-N7100.
Things I have tried and the result is failure:
1. Changing USB
2. Updating drivers
3. Tried KIES firmware recovery
4. Tried to root
5. Tried to flash original ROM/firmware
6. Tried to flash PIT
7. Tried to nand erase all
These are the logs:
<ID:0/005> Erase...
<ID:0/005>
<ID:0/005> Complete(Write) operation failed.
Other than that, I can't do any **** on this. I'm tired.

failed to mount /efs

Hi,
I have somehow managed to make me tablet unusable. I do not get any wifi or lte connectivity (SIM is not read correctly).
I tried to flash via odin and using kies emergency firmware recovery. While not flashing the custom recovery, entering the "original" recovery throws this error: E: failed to mount /efs (Invalid argument)
Could someone please help me restore it? (maybe you can take a backup of yours?)
I have a p605 16Gb LTE

failed to mount /efs (Invalid argument) Issue
Hi, First Off I should state i'm still a bit of a noob with all this stuff...I'm currently experiencing trouble with my Samsung galxey note 2 GT-N7105
Its stuck in a boot loop and When I go in to recovery It comes up In red writing E:failed to mount /efs (invailed argument) I DID have CWM recovery But for some reason Its gone and Only comes up with the stock android system recovery.
I've tried everything I can think of.. I've done a factory reset with no luck, I've tried re-installing CWM via odin , I installed a stock rom via odin no luck and when I try connecting it to kies It recognizes that its plugged in but just keeps Saying "connecting"
I'm really stuck here and out of my depth.
thanks in advance.

Bricked: SGH-317 using n7100

Tried updating my phone today. Rooted SGH-i317 on 4.2.2
Thought i had the correct file but now it appears i dont
getting E:failed to mount /system (invalid argument)\
#manual mode#
-- appling Multi-csc...
E:failed to mount /system (invalid argument)
can't mount '/system'(invalid argument)
E:fialed to mount /system (invalid argument)
it looks like i may have used an N7100 file to flash and thats when s*** hit the fan.
at the top of recovery mode i have
Android system revoery <3e>
KOT49H.N7100XXUFND3
end result would obviously like to be back to a working phone and up to date on 4.4.2. Any help is greatly appreciated. I have tried flashing a few files in odin without success. A lot of the files are nowhere to be found at this point, online, and would appreciate any input. Thanks guys.
i was SUCCESSFULLY able to get back to a stable working version, 4.1.1 i cannot attach of the file i had to flash with Odin, but if you search for KIES_HOME_I317UCALJ2_I317ATTALJ2_215287_REV04_user_low_ship.tar you will DEFINITELY find it. . Basically went back into download mode, selected this file with odin under AP, then plugged in and hit start. Flashed, worked, success. now to update to 4.4..

** ODIN Stock flash fail **

Today I was using my T-mobile galaxy note 2 (sgh-t889) perfectly. I've recently installed the OCT-OS Lollipop rom by hedwig34 and its been working fine until today
My phone rebooted and it displayed the Samsung Galaxy Note II Splash Screen for a while so I tried to do a battery pull but It kept displaying.
It just displays and shows nothing else, no reboots, just "Samsung Galaxy Note II"
Anyway, I've been trying to flash the stock roms that are on the Android Development forums, but when I do, Odin shows me this:
<ID:0/008> Added!!
<ID:0/008> Odin v.3 engine (ID:8)..
<ID:0/008> File analysis..
<ID:0/008> SetupConnection..

<ID:0/008> Get PIT for mapping..
<ID:0/008> Firmware update start..
<ID:0/008> boot.img
<ID:0/008> NAND Write Start!!
<ID:0/008> FAIL!
<OSM> All threads completed. (succeed 0 / failed 1)
Whenever I try to install custom recoveries or root by itself, it shows something similar.
I don't think NAND Write start FAIL looks anything good.
Can someone please help me!
Edit: I'm now able to enter recovery (TWRP 2.7.2.0) but it says I have no OS installed:good:
Recovery Problems
So, I've gotten myself into TWRP v2.7.2.0 and I was checking Install to see If I can install a new ROM and first thing I see is (Internal Storage 0 MB) and I'm scrolling through the stuff and it shows folders like cache, data, dev, efc, lib, preload, sbin, system, tmp and others. I can't mount anything (It doesn't give me option for USB Storage Mounting. the log shows something like this:
E: Unable to mount ' /data'
E: Unable to mount ' /efs'
E: Unable to mount internal storage.
E: Unable to mount ' /storage'
And so on..
And when I insert my SD card and reboot into recovery, It still shows the internal storage(0 MB) and doesn't show the contents in my SD Card.
OK I did some research and it seems that somehow i formatted all the data on the device. I've managed to transfer the Note 4 DN4 rom that I found on the Android Development forums. when I try to install it, It'll give me this:
Error flashing zip '/sdcard/DN4_v2 for lte(2).zip'
Updating partition details...
E: Unable to mount '/efs'
E: Unable to mount '/data'
E: Unable to mount '/data'
E: Unable to mount '/cache'
E: Unable to mount '/system'
E: Unable to mount '/data'
E: Unable to mount internal storage.

So, Heres what I know now:
I've got no OS installed on the phone now. I have several partitions corrupted. .Pit files probably could fix it. t889 doesn't have any working .pit files. Even if they did work Odin wouldn't flash them anyway.
I've received no help so far from anybody and nothing seems to be working... I can't believe this topic has 60+ or so views but theres 0 people to help.
ANYONE??? I've been waiting all day for any response!
I literally just got the phone 4 days ago...
Even if you can't give me an solution, atleast tell me what's going on?!?!?
I had a 0 MB problem on my HTC One X. Boot into TWRP, mount USB, connect to PC, format data partition using fat32. Good luck. Hope fully, this will allow you to access internal memory.
Did you try flashing Odin without a pit file or re-partitioning? Did you try the stock firmware from sammobile.com?

I have exact same issues.

so is your issue resolved now?
news about the problem?
There is nothing that explains a resolve to this situation. twrp absolutely useless as it doesn't even recognize usb or the ext sd card. odin fails, and no info to get thru it. Wish someone could post some fix. Have tried everything in the book. wanted to fix my note 2 for a family member.
Same issue
I had my phone working perfectly with an unofficial CM 13.1. One day my battery ran a little low, and after I charged it the darned thing got stuck at the "Samsung Galaxy Note II" boot screen. After going into TWRP I noticed that it could not access any of the partitions, nor the external SD card. I have googled about every combination of search terms I can think of, but this thread was the only one that came close to describing my situation.
Following a suggestion I saw somewhere, I have tried flashing the stock rom but Odin chokes at the system.img file. I then try to boot into recovery (now stock) and it says the flashing went wrong and to go back to Kies in recovery mode. I am able to use Odin to re-flash TWRP and boot up in that, but it cannot mount anything. The /etc/fstab file has entries for the partitions but they are invalid and do not point to any device. I looked in /dev/block but there is only one partition showing for the mmcblk0 device, mmcblk0p1. There used to be at least 16 (/data used to point to /dev/block/mmcblk0p16). I tried using Odin to flash a .pit file but it does nothing.
At this point my Note II is a doorstop. This is my only phone so I am stuck. Any help will be appreciated.
Help me, Obi Wan Kenobi. You're my only hope.
My note 2 started same way, some apps starts to stop, getting a lot of errors, then I tried to factory reset, now only shows t samsung logo, tried odin.

Of course I did. I have twrp recovery, I cant format my device. Unable to mount any folder.
If you tried using different USB cables, USB ports, and different versions of Odin, the phone may need to be force flashed using hardware like an Octopus Box or the memory chip is defective.
Same. Let my battery run dead on t0lte that was running lineageOS and now it boots to Samsung Note II . TWRP cannot mount internal or external storage. This is bad!
