Phone is working again!!!
Thanks On Droid1234 for the information. I flashed it with the file you told me about i5500XXJED and the phone is working now. I tried to upgrade it with Kies but it gave me a message that my phone can't be upgraded. I looked for the version of android 2.2 for my phone - pcode: GT-I5500KAVOP but can't find it.
