I had to do that on my Xperia T because getting into flashmode the normal way didn't work
Thanks for the suggestion but it didn't appear to make any difference but something I realised is that I might have been holding the volume - fir too long. Also the green LED indicating flashmode doesn't stay on just flashes briefly. Still I was able to get PCC to see the flashmode and 'repair' it but it has made no difference. In USB mode MTP the battery is not charging hen connected to a PC and is when connected in MSC mode. I realise it is not hugely important but it would be nice to have it working the way it as two days ago
PCC doesn't recognise the phone nor Media Go; maybe it is pc driver issue though I have uninstalled and reinstalled the pcc software.
