Flashing Error

I tried flashing my Sony Xperia Z Ultra many times, but it failed...

Actually, that time i was flashing custom rom, but it couldn't get into the system, and then i tried to flash another rom, and it got bootloop since then...

I always got error, and the flashing aborted...

Here is the log...
