I am a rather experienced user when it comes to flashing/using odin and I had successfully updated to JVK from JV1 and had been using it for a few days. I decided I wanted to use a ROM now, so I went to http://romkitchen.org/beta/ and downloaded a no-wipe rom. I was already rooted but needed CWM so I flashed the new version of CF-Root. Everything worked fine so I used CWM to flash the rom. It started an endless boot cycle (Just the galaxy s i9000 words over and over again) so I decided to just repartition and flash JVK with Odin again as I had a backup and wouldn't lose anything. That worked normally but once the phone started restarting (before it got to any boot image) it went to a password entry box. These were the exact same files that I had used to to flash gingerbread before and I have never had this happen to me before. The only physical button that does anything is the menu button which dims the screen. Pulling out the battery/restarting/reflashing JVK or JV1 doesn't help. Froyo (JS5) does work though so I am using that now. I have tried 3 different versions of Odin, going to JV1 then JVK, different .pit downloads, bootloader and non bootloader version of JVK, none of them make a difference, always the password. I have tried all my passwords, and none of them work.
Anyone have any ideas?
