My xperia neo/v is not booting after updating software. only 'sony' and then 'xperia' and then repeating the same continuously.
Take out the battery and put it back in.Have you tried that?
If that doesn't work then re-install the latest update with SUS
Update Service (SUS)
PC Companion (PCC)
Bridge (for Mac)
