[Q] EFS issue GT-N7105 please help

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.

Soft brick - cannot flash via recovery or Odin

Basically woke up with my phone as a brick... phone crashed when my alarm was supposed to go off (luckily I was already awake) and now hangs on the boot splash screen.
Device is an i747m, previously running S3Rx 3.0 (Android 4.3) with MK5 bootloader and modem. CWM 6.0.4.7 installed.
I am able to boot into both recovery and download mode.
However, in recovery mode, I get the errors:
Code:
E: Can't mount /cache/recovery/command
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: Can't mount /cache/recovery/last_log
E: Can't open /cache/recovery/last_log
E: Can't mount /cache/recovery/last_install
E: Can't open /cache/recovery/last_install
Furthermore, if I try to factory reset, I get the error:
Code:
Formatting /data...
Error mounting /data!
While in recovery, I am not able to flash a new recovery or ROM. There are no errors when flashing, however, after rebooting nothing has changed. I'm assuming that's because the system cannot access the storage.
Through Odin, I can flash TWRP with no errors. However, once I try to boot into recovery, I am still on CWM 6.0.4.7.
Through Odin, I am unable to flash ROMs (trying to flash 4.3 MK5 stock rom). I am using Odin 3.07 on a W7 x64 computer with Samsung drivers installed and an official Samsung USB cable.
I receive the error:
Code:

It appears that there is a problem with the internal memory since I can't read/write, but I am unsure if it is fixable.
I have come across this thread, but I am skeptical if it will work since it is for the Verizon S3.
I also came across this thread in my research, but I can't get cygwin to download >.> It seems promising, but I am unable to try it at the moment.
Any help or suggestions would be greatly appreciated. Please let me know if any additional information is required.

Have you tried flashing a 4.4.2 ROM?

Yes, I have tried flashing the 4.4.2 NE6 ROM using Odin with the same result (NAND write fails).
I have also tried flashing via Heimdall. No success there either. Heimdall is able to upload the file to my device (according to the progress bar), but then terminates with, ERROR: Failed to confirm end of file transfer sequence!
Also, the PIT file I extracted from my device via Heimdall does not match a "normal" i747m 16gb PIT found on the internet... I also cannot flash the 'normal' PIT onto my device (same error as above).

It's possible the internal memory chip is damaged which is not easy to repair. Simplest fix may be to buy a used s3 with a smashed screen and do a motherboard swap.

Yeah, that's what I'm thinking too at this point since I can't get anything to write onto the memory. I just loaded up Aroma File Manager through recovery and it looks like most of the files on my internal memory are gone, even though I have not been able to successfully factory reset through recovery. At least I have TiBkps of everything.
Do you think I could franken-phone using an i9100 (international model S3)?

Boot into download to find out.

GT-N7100 Soft Brick? Phone block in Samsung galaxy Note II screen. Dont Star

Hello everybody
At dawn last Saturday, my phone rebooted only, did not go beyond the screen of SAMSUNG GALAXY NOTE II; I did wipes and did not work, try to re install the ROM stock and ODIN pulls me error. I have tried several rom stock and nothing, try using the ADB SIDELOAD method and it gives me about 55% error of loading the rom (Set_metadata_recursive: some changes failed
Updater process ended with error: 7 ")
The phone enters DOWNLOADING mode and Recovery mode. (USE TWRP V.3.0.2)
The recovery log shows a series of errors that I do not understand very well and lead me to think that there may be an error in the computer's HARDWARE (eMMC Chip?)
I would appreciate if someone could confirm the error of HARDWARE so I do not waste my time downloading files that will not serve if that is the problem.....
Thank you
Spanish version
En la madrugada del pasado Sabado, mi telefono se reinicio solo, no paso mas alla de la pantallazo de SAMSUNG GALAXY NOTE II; hice wipes y no funciono, trate de re instalar la stock rom y ODIN me saca error. He probado varias stock rom y nada, trate de usar el metodo ADB SIDELOAD y me da error al 55% aproximadamente de cargar la rom(Set_metadata_recursive: some changes failed
updater process ended with error:7")
el telefono entra en modo DOWNLOADING y modo Recovery. (USO TWRP V.3.0.2)
el registro del recovery muestra una serie de errores que no entiendo muy bien y me llevan a pensar que puede haber un error en el HARDWARE del equipo (eMMC Chip?)
agradeceria si alguien me pudiera confirmar el error de HARDWARE para no perder mas mi tiempo bajando archivos que no van ha servir si ese es el problema.
gracias

i think the same about eMMC problem, but my question is: if the problem is a eMMC bug, it can fix with any software? or the unique solution its change?

Odin stops when trying to flash the sboot.bin file because you need to use the original Samsung USB cable, use a different USB port, the rom is not for the phone, or the bootloader in the phone is newer than the bootloader in the rom.

Hmmm well ... i used the stock rom 4.4.2 installed in my phone before rooted; downloading from sammobile, i try with 2 different cables in the 3 USB ports of my laptop.... The bootloader theme is not clear to me ... As can be the bootloader newer than the bootloader of the rom if i try to flash the same stock rom that i haved before the problem?
its possible to flash only a old bootloader? after that flash the stock rom?

Try to confirm the bootloader version in the phone because the sboot.bin file is a bootloader. You can't flash an old bootloader over the newer bootloader and this could be why Odin stops.

Any update on this?

Did you find anything? I am experiencing the exact same issue.

Hi @mcastrojz,
I have exactly the same problem as your. Did you fix your phone yet. I brought my phone to a few phone store and they tell me storage has been broken, but I dont believe it, so I come here and saw your post.

Hi manhtidus; I have not yet been able to repair the phone; I have taken it to technical service and the only thing they are right to say is that you have to change the motherboard ... unfortunately I do not have money at the moment to do that and also to buy a new phone.....

can you try to install this file via odin
https://forum.xda-developers.com/attachment.php?attachmentid=1394028&d=1349983558
it is recovery-cache-fix by chainfire
it is only a test (in your case ) and it is not a fix ,nor a solution
and things maybe became worst (brick your phone)
so you could try it at your own risk
if the installation pass OK , so I think you have ray of hope

@xcorona: Thanks for reply, I tried install that file with hope, but it cant help, at least in my case.
P.s: In a crazy moments, I tried to download and flash anything I find on this forum, but no chance.

@manhtidus
note 2 & S 3 (16 giga ) as you know suffering from Bad manufacturing ( internal storage like hard drive in PC ) , not all the phones
This problem appears after a period , it does not have a specific reason 100% for the emergence of this problem , so they call it (insane chip)
when the phone reach that point , PC in almost cases will not solve it
it only can be done via box (as easy jtag ) or replacing the hard or the whole motherboard
and i am sorry to say that all the next steps via PC it will be just wasting time
so it will be only Your decision time vs money

Thanks @xcorona, I think you gave me the answer I finding on the internet for a long time.
Cause my phone has been working very great from 4 years ago with stock rom, util it has this problem after I rooted and used some custom rom, so I thought its a software problem (because of my stupid), and tried to find solution on this forum.
Last chance, I brought to cell store where they tall me have to replace mainboard or internal storage of the phone, but I dont think that's the truth.
Now, I'll not try to fix my phone and let it rest in peace.
Thanks again for your great answer.

[Q]N7100 - internal storage is listed as 0MB, Odin Complete(Write) operation failed

Odin fails when trying to install sboot.bin for one or all of these reasons:
the ROM is not made for the phone;
need to use the original Samsung USB cable;
need to use a different USB 2.0 port;
the ROM's bootloader is older than the bootloader in the phone; and/or
the phone's memory chip has failed and you need to replace the motherboard.
Did the ROM come from sammobile.com?

The "phone's memory chip" part is the scariest part and I hope its not
I used "RESURRECTION REMIX [5.8.0]" Rom, and I tried flash Stock Rom N7100XXUFNI4_N7100OLBFNI1_XXV but it failed.
And I don't understand part "the ROM's bootloader is older than the bootloader in the phone". Where can I check it?

You confirmed that the phone model # is gt-n7100 in download mode? Did you get the stock firmware for the n7100 from here: https://www.sammobile.com/firmwares/database/GT-N7100/ ?

Sounds like the memory chip could be defective.
Try flashing twrp 2.87 and see if that works. If it doesn't work, you can try a cell repair shop to see if they can force flash it.

I admit it doesn't look good.
A cheaper solution may be to buy a used phone with a smashed screen and working motherboard.

Thanks for your helping.
I'll look for some chance from terminal or adb sideload, bad thing is last night it still working perfectly. so sad

Maybe not right PIT file, I flashed 2 file "PIT_N7100_16GB_20121102.pit", "t03g_0907.pit" found on internet, but not working

Looks like you'll have to either take it to a cell shop or replace the motherboard.

Tried to use adb sideload to install other recovery, install perfect but after restart seem nothing change.
Tried change timezone on TWRP, but after restart, it did not save changes.

Same happened with my note 2 tried every thing but Nand is corrupted .there are only 50% chance .

Wow, I guest I'm the first one get this error:
After find out can push file to mobile by adb push XXX, I tried reinstall rom, and alot of stuffs to test, now I get this error when use "Data Format" on TWRP: "Unable to get block size for wipping crypto footer." and still

Unable to format to remove encryption --> I guess I need to do something in here
Failed to mount /efs, /cache /system /data

Hope someone will help my resolve this

Update:
Sadly, After reboot phone, everything gone, nothing saved.
In my /dev/block/ there is no file mmcblk0p0 - 16 , just have loop0-7, ram0-15
