[Q] Flashtool cannot get passed System.sin

[Gnubaver]

I think my Z1 is semibricked. I can enter flashmode and stuff and it vibrates. It sometimes boots up and says Update failed connect to computer and try again. (This was after it failed with Sony Companion)

Now im trying to flash with flashtool in flashmode. It writes alot of files but it always stops at system.sin

What should i do?

I have tried with two different firmwares.

( The phone is a C6903 Unbranded)

I now flashed and excluded system.sin

It went thru. But now its stuck on Sony Boot Logo.

Any idea what the next step should be?

I reinstalled Sony Companion and reinstalled Flashtool Drivers, but the problem still exists. What am i doing wrong?
