Soft Brick - FAILED TO MOUNT SYSTEM - Help

Good night guys, so there's my problem:
I was on DN 0.6.1 custom ROM, TWRP 3.0.2.0 and rooted. Today, i wanted to go back to stock ROM, so, I downloaded the stock firmware throught sammobile, and tried to install it throught ODIN 3.11, but it's stopped at system.img, and remained stuck in it for a long time. so i decided to restart the phone..
Then it's showed the follow message:
firmware upgrade encountered an issue note 4. Please select recovery mode on kies and try again.
So, i tried to re-flash throught ODIN, but stucked at system.img again, after it, I downloaded KIES and tried restore it, but it's stopped at 2%.
I wasn't abble to go to recovery mode, only download mode, so, i extracted the ROM file, and flashed only the boot.img through ODIN. Now it's boot to recovery...
I wiped data/cache, but the following error showed up:
E: Failed to mount system (invalid argument).
and now i can't find a solution for it.. tried to do amost anything that i could find on the internet, but none solved my problem...
I'm wanting to flash PIT + CSC + PDA file, using the repartition option on ODIN, but i'm afraid that may brick my phone for ever...
I'm following this tutorial by now: http://forum.xda-developers.com/not...te-4-pit-files-repartiton-f-g-c-t-w8-t3282641
And i need this CSC file, because my phone is the C version, could someone give me link to download it ? couldn't find in any place.
ANd there's someone who could help me ? i'm very concerned about it because i don't have money to buy another phone at the moment...
Thanks, and yes, already looked at XDA for a answer but couldn't fine any.
THANK YOU :good:

Hello I am using Yureka
Yesterday I was flashing Hexagon ROM by Sushant More. Thats why I wiped the Data,System and Dalvik Cache & Cache but after wiping out it showed some errors

Corrupted partitions?

Hello, I was trying to downgrade from N to MM and somehow i lost my system and data partition. I have the custom revolution recovery and i cant mount data or system on the mount menu, also when i try to flash any package it gives me the error "cant mout /datad/system oartition". I also tried to extract system from a original firmware and tried to flash it with fastboot, but it gives me the error "FAILED (remote: sparse flash write failure)". Is there a way to get back my partitions and reflash MM on here, or have i just won a new (very slim) paperweight? Any help would be much appreciated sice im kinda dependent on this phone.

For some reason system is able to mount now... but still nothing in the data partition , it show 0B

i have the same issue

Have you tried to flash oeminfo?

Try flashing right modem through recovery, or use Odin to flash stock rom or you can try kies to recover it.

Thanks for your reply.
Currently got stock rom on phone but it won't boot, it's stuck at Samsung logo.
Device is rooted and got twrp.
Kies is stuck trying to figure out the device that is connected. And when i try recovery of firmware or something of the like(Kies is installed in french) says this model cannot be reinitialized.
Also like i said i have no backup, so no recovery key for kies either.
But the internal sdcard is recognized by Windows.
Don't know what else to do. I had no problem flashing modem.img flashed OK and such.
Is it normal when in recovery mode when i run a graphics test it says error?
Is it just a bug from the recovery mode?

Hoorray! Found Something that worked for me i'd like to share with you. Thanks to this post : https://forum.xda-developers.com/s6-edge-plus/development/updating-t3210266
Many thanks!!
