[Android Q&A, Help & Troubleshooting] darklord2:
Hello everybody,

This is about my Samsung Galaxy Note with 100% original/untouched hardware/software (all stock) which is currently hanged on the boot screen.

However, it can be applied to any android phone and therefore I posted it here.

What happened:

I plugged in the charger into my Samsung Galaxy Note (it was functioning normal).

After an hour I realized that the phone is constantly showing the SAMSUNG logo which appears at the boot time.

I unplugged the charger and let the phone untouched for another 5 minutes but nothing happened.

The screen was keep showing the SAMSUNG logo.

I removed the battery and inserted it back again, then phone started automatically but hanged again on the SAMSUNG logo.

I switched off the phone via long pressing the POWER button, immediately after power down the phone automatically turned on in the same hanged situation.

What I have tried so far:

0. Removing the MMC and SIM and removing the battery for more than an hour.

No success here!

1. Booting up the phone into recovery menu using the key combination (VOLUME UP + HOME + POWER).

Result: a dead Android figure appears with an exclamation mark, following by a bunch of red error messages like below:

E: failed to mount /efs (No such file or directory)
E: failed to mount /system (No such file or directory)
# MANUAL MODE #
-- Appling Multi-CSC...
E: failed to mount /system (No such file or directory)
can't mount '/system' (No such file or directory)
E: failed to mount /cache (No such file or directory)
can't mount '/cache' (No such file or directory)
E: failed to mount /cache (No such file or directory)
E: can't mount /cache/recovery/last_recovery
E: failed to mount /data (No such file or directory)
E: Can't mount /data/log/recovery_log.txt
E: failed to mount /system (No such file or directory)
E: Can't mount /cache/recovery/log
E: Can't open mount /cache/recovery/log

Afterwards the blue recovery menu appears on top of these errors and regardless of the chosen option similar error messages appear on the screen.

No Success here!

2. Flashing a custom recovery tool (WTRP) using ODIN

Downloading the WTRP from their official vebsite.

Downloading the ODIN software (

various versions

).

Booing up the device into Download menu using the key combination (VOLUME DOWN + HOME + POWER).

Connecting the phone to ODIN (

ran as administrator

).

Starting the process and immediately ODIN said:

<ID:0/007> Complete(Write) operation failed.

No success here!

3. Flashing the Stock firmware using ODIN

Downloading the proper stock firmware (

from various sources

).

Downloading the ODIN software (

various versions

).

Booing up the device into Download menu using the key combination (VOLUME DOWN + HOME + POWER).

Connecting the phone to ODIN (

ran as administrator

).

Starting the process and immediately ODIN said:

<ID:0/007> Added!!
<OSM> Enter CS for MD5..
<OSM> Check MD5.. Do not unplug the cable..
<OSM> Please wait..
<OSM> Checking MD5 finished Sucessfully..
<OSM> Leave CS..
<ID:0/007> Firmware update start..
<ID:0/007> SingleDownload.
<ID:0/007> sboot.bin
<ID:0/007> FAIL!
<ID:0/007>
<ID:0/007> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)

All above steps were done multiple times, using multiple cables, multiple ODIN versions, stock firmware download from multiple sources and the result was always identical... "Complete(Write) operation failed".

No success here!

My guess is a dead eMMC.

Any suggestion is highly appreciated.

Thanks in advance!
