Have been trying to update my galaxy s2 with jelly bean, everytime i connect it to kies on the laptop it tells me a firmware update is due, downloads the update then disconnects phone from laptop and closes kies . Update not loading onto phone, any ideas...
Settings, about phone, software update, kies is rubbish.
Or
Start kies, click on tools, firmware initialisation, enter details it asks for, this will put original firmware back on your phone, and update it to jellybean after its finished.
BACK UP ALL YOUR CONTACTS ETC ETC FIRST
