Flash my Xperia 10.

[Davhill]

Hello All, 

I'm looking for a saviour who can sort my phone out for me. Please bear with me while I tell the story.

I bought a new Xperia 10 from an eBay seller. When it showed up, I put on a tempered glass screen cover and put it in a wallet I'd bought for it. All was well until I couldn't enable Wi-Fi calling, the option wasn't there. I need thsi facility because I live in a mobile signal black spot. 

Extended talks with Sony and my provider (1p Mobile) showed that the problem lay in the phone's being a Taiwanese market model.I persuaded eBay into refunding me but Sony has washed its hands of any giving me any further help or advice. 

Now, I have a copy of the UK firmware. (Please see pic below.) This is a 2.131Gb ftf file.

I put the Xperia Flash Tool on my PC and it told me that my device is locked. 

I found out that the bootloader can be unlocked. 

This is where I got out of my depth. I started on PCs when IBM was king and I've never 

got into anything more than word processing and work on jpegs.

So, how about this? 

1: I post the phone to someone in the UK who can put the firmware in my phone and check the Wi-Fi calling works. I could send the UK firmware out as an email attachement or put it on a USB stick. I could include a working SIM card and send a few quid for doing the job. I would, of course, cover the postage both ways.
