Samsung Galaxy S4 - Can't Mount E: /sdcard problem then bricked

[Ya Basha]

Hello Experts,

I need some help please, yesterday when I was entering a new phone number in my rooted (S4 I9500) suddenly it restarted and kept restarting when reaching Samsung Logo then I went to the recovery mode and did wipe data/factory reset, the following errors messages appeared:
Formatting /data
Error mounting /data!
Skipping format
Formatting /cache
Formatting /sd-ext
Formatting /sdcard/.android_secure
Error mounting /sdcard/.android_secure
Skipping format
E: Can't open /cache/recovery/log
E: Can't open /cache/recovery/log
E: Can't open /cache/recovery/last_log
E: Can't open /cache/recovery/last_log

I tried all the possible things in the recovery mode but no luck and can't mount /sdcard error message came, then I went to the download mode to install the stock rom but on the odin screen fail error came at that point when I restarted my phone it was bricked and couldn't boot the device. :'( :'(

I think that my internal sdcard was corrupted, did I lost the phone? is there any solution?

I didn't do any issue to cause this I was just entering a new phone number, I rooted my phone before 4 months and during this time it was working correctly.

Any help will be appreciated,
