[Q] Bricked or not ? MMC: mmc_read fail.

Hy, I own an S5 G900F. I flashed a stock rom latest version then my S5 root before flashing a rom Omega 2. Everything worked perfectly until I decided to change my sdcard having taken care to move all the files present on my old sd card on news.
At start of my S5 nothing worked, I have the screen that lights up with the SAMSUNG GALAXY S5 logo, powered by ANDROID but the top right I have the following message in red: kernel is not enforced seandroid and yellow: set warranty bit kernel.
I can not switch to recovery since disappeared, I just can enter download mode.
With odin so I tried to flash my S5 with stock rom (XEF-G900FXXU1ANE2-20140519102224).
Here is the odin message when I load this rom:

Enter CS for MD5 ..
Check MD5 .. Do not unplug the cable ..
Please wait ..
900FXXU1ANE2_G900FOXX1AND3_G900FXXU1ANE2_HOME.tar. md5 is valid.
Checking MD5 finished Sucessfully
..
Leave CS.

My S5 is well recognized by odin, it tells me blue com port 3 and
Added!

Top right of the screen of my S5 I have these messages:

ODIN MODE
PRODUCT-NAME: SM-G900F
CURRENT BINARY: CUSTOM
SYSTEM STATUS: OFFICIAL
LOCK REACTIVATION (KK): OFF
KNOX WARRANTY VOID: 0x1 (4)
QUALCOMM SECUREBOOT: ENABLE (CBS)
SWREV RP: S1, T1, R1, A1, P1
UDC: START

I run flash with odin:

Odin v.3 engine (ID: 3) ..
File analysis ..
SetupConnection ..
Initialzation ..
Get PIT for mapping ..

There is no PIT partition.
All threads completed. (succeed 0 / failed 1)

The flash stops with S5 on the screen messages:

MMC: mmc_read fail
ODIN: flash read failure

I do not know what to do! Is it a hardware brick or a simple software problem??
Thank you for trying to help me if it is possible. I hope to have been clear :confused:
best regards,

Sorry for my english, this is a google translation :(
