I have a big problem with my Galaxy S immediately after upgrading to the JPM/Froyo firmware. Immediately after the update the phone attempted to reboot, and now stays on the Galaxy S logo way too long before the screen goes blank and only the bottom two buttons are illuminated. And it just stays like that. I have a feeling that it might have something to do with the OneClickLagFix that was installed on the phone; maybe the upgrade didn't like the lag fix being there. Also, on pressing VolumeDn, Home and Power to get the recovery screen, the screen is replaced with a yellow "Downloading... Do not turn off Target!!!" splash. So there are no recovery options. Any help would be appreciated. Thanks. EDIT: I misread the screen, and it is much more likely that it was JM1 that I installed, if that makes a difference.
