Hey T_r_i_s no probs I myself sometimes don't see replies. My streak reports no charger detected, I kept playing a little bit with it to see if I could go back to 0% battery juice to see if I could kick start the charging again but that didn't help. The pics you posted in MMI 09 option gives me NO CHARGER DETECTED while yours is detected, I've plugged the original, a Kodak one 700ma did a sony too nothing worked, even got a slacker dock just to try, as no one in my country has a streak that I know off.
Even looking on the internet no one seems to have fixed this issue without taking it back. My streak is a beta unit so not an option for me.
It sounds like you and PECHU77 have the same issue? Do either of you have a multimeter to check whether there is a charge/current coming from the lead?
