Ok, I decided to update my phone to Froyo today through the latest version of Kies, the firmware downloads but when it comes to upgrading, it doesn't proceed, instead, my USB device apparently becomes unrecognised and the whole thing stops. Meanwhile, I restarted my phone and loaded up Kies again in attempt to try it, apparently, I had to recover the firmware or something of that sort and Kies told me to hold DOWN + MENU + POWER to get into the recovery mode. When pressing those buttons, I get the the same "Download...Do not turn off Target!!!" message instead.
Loading up "recovery mode" by pressing UP + MENU + POWER works fine though so I don't know what recovery mode Kies is talking about. Any help with upgrading to Froyo would be appreciated. Thank you.
P.S. The phone also works fine after restarting.
