Sola in boot loop. Cannot use PC companion.

Hi,

My Xperia Sola (MT27i) is in boot loop. I cannot use PC companion to update/repair because the device won't start.

When I try to use flashtool I get the error, "ERROR - Drivers need to be installed for connected device." and "ERROR - You can find them in the drivers folder of Flashtool". I have tried installing the drivers from drivers folder but that didn't help me.

Is there any other way I can boot/flash my device?

Z1 Compact connection through PC Companion error

Hi! I used to tranfer files to my Z1C through PC Companion's Wifi Connection, on WIndows 8, but now that I updated to Windows 10 it doesn't work. What should I do?

Update Via PC Companion not working

Hello all.
I need some help how to update the z2 to lollipop.
I've read stuff on internet, but I simply can not do it.
The error 2003 is killing me... And I do not know what to do.

A month ago I bought a z2 for my brother and it was/is on kitkat.
Today, I bought a z2 for my father and there was lollipop already installed.
I bought both phones via Ebay.
The phones have the same Model Number.
On the kitkat z2 I cant update via OTA either.

Could you PLEASE tell me what to do?
I have read something, that my bootloader may be unlocked and I have to relock it.
Is that true? And if yes, how can I check if my bootloader is locked?

Thanks in advance!
