Can someone help me, my friend's phone suddenly bootloop,
before this using Milky mod.

I already tried flash using ODIN to xxjvt. try many times.
I got this error in CWM E:failed to mount /sdcard (No such file or directory).

This phone can go to download mode and CWM without problem.
Anyone experience this before? Please help me..

Below is the screenshot in recovery 3e, after I flash xxjvt using odin.
