Because i never could...

Flashtool stopped working while I was flashing nAa-11 kernel. When I restarted flashtool it gave me the error.

hi, i was flashing the same kernel onto my sisters x10 mini pro and when i went to flash i got the error before it allowed me to flash the kernel, i used PC companion to repair, located in the software update section once i did that, i just unlocked the bootloader and root. hope this helps you.

I have triede with pc companion, it will not let me update, and it is not possible for me to put the phone into USB debugging, because the phone do not startup. I realy hoped that someone other than me has had this error before. But when I google the error, it doesn't come up with much.

I guess there's nothing to do then. I hoped there was some one other than me who had experienced the same as I did. Can anyone tell me if there is other things to try before I throw it into the graveyard.

Hello, I just recovered a friend's phone from this problem. Nothing worked before but I found the solution, at least for me.

First I want to tell what I tried:

• Flashing with PC Suite
• Flashing with PC Companion
• Flashing with FlashTool
• Flashing with SETool Box 2

Nothing worked. Mainly because the dumbass of my friend tried to update latest version while it failed (don't know if battery problem, cable or whatever).

The problem is that it just hanged in "Sony Ericsson" screen and not recovery possible.

And when flashing I got:

ERROR - ERR_SEVERITY="MAJOR";ERR_CLASS="SECURITY_CLASS";ER R_DYNAMIC="SIN header verification failed"


=== Now how I solved it ===

What I did is download the u20i1.6 binary fron XDA developers. It said it's a zip but it's just a RAR.

I had to uncompress it in a folder. And create a bundle with FlashTool with those files. I will try to upload this.

Then I flashed it. It worked without the error.


-------------------
- At the time of writing this. I upgraded the phone with the PC Companion but
- after updating the phone just got hanged again. It just flash red light when
- swithing on. I don't know why. Have to see.
- Update: Was not hanged I just had to force off (long press on the power button) and then on. The PC Companion finished updating.
- Update: Flashed last version and now SETool Box2 is not able to unlock. Better to stay on 2.X.
