Help! My Galaxy i5500 was bust, so I went to use my old i7500. It all went well, and it started up first time, it then tried to update all my emails, and ..... dead!! Since then I've occassionally been able to get it to start up when plugged in (say three times over a week of trying), but it falls short of a full boot up and goes dead again. Tried both of my batteries, and when plugged in it seems to be on full charge, but nothing. I had upgraded to IK4, but nothing major else done to it. Can't get it into any recovery mode or download mode at all. Just stuck now ... anybody help?
