W850i

My daughter lost some water on this,only minimal amount i think,nit into sink or anythng like that however it does not power up,red colour on the back of phone,this was 2-3 months down the line,took it to shop then and told me ruined however reading now i realise we tried to power it up and this was a mistake,dug the phone out today and whne i put the battery in the on/off button vibrates but nothing else,is there hope for it i wonder.
put the battery and the phone separately in the airing cupboard to try and dry,maybe too late now.

any views appreciated

Read this XS++ 3.1 Guide-Flashing, Customizing, Recovering - Top Sony Forums and try to connect your phone with XS++ and if XS recognize phone post log here without IMEI number and than will see

Hi, it should have opened, and dry, or cleaning with alcohol, it should have no power, if they have hopes, only to clean it with alcohol with the phone open.
PS: a flash did not work here, this is physical, it is no system.

greetings.
