Hello, I have Android 2.1 and I wanted to upgrade it to 2.2 so I downloaded Kies on my laptop but it is blank when I open it, I mean in the sidebar there's nothing, all texts are written in gray except Tools and Help, under the File menu even the Add file to GT-I5500 is written in gray. Last night it worked a little bit, the option wasn't in grey and it let me transfer files to my mobile phone, when I clicked on Upgrade Firmware and Initialisation it asked my S/N and Device Model, I wrote the GT-I5500 and the Serial Number written on my battery but it said the S/N was wrong. Today it doesn't totally work anymore, my phone keeps on ticking USB debugging mode when I plug my mobile in my PC even though I have unticked it. PS. Could anyone kindly respond me via Google Talk too? I rarely visit this forum, I thought I could give my Google Talk to anyone in case they would like a fast response.
