Hello
I am trying to fix an old good phone, a W800i.
I remember I had the same problem some years ago and I restored with Sony Ericsson Update Service or reflashed the firmware somehow, if I remember correctly.

I'm trying to update it again, using SEUS but SEUS auto-updates and my phone is no longer on the list so I will need other methods to recover it.

Can somebody help?
Post some guides and where I can get the firmware for this good old phone of mine?
