I downloaded version 1.4.3 for the tsu500 and installed it. then I updated my brand new neo and it got half way through and a window popped up that says unable to repair or install update. I have tried several times to do it again, also have redownloaded the update and used s different computer. Now the neo will not function at all, no lights no screen no response. I have tried to reset it- nothing. I have taken the batteries out for more than five hours to let it clear out but nothing. Is there anything I can do before sending this back to philips? Help from the guru's would be greatly appreciated!
