Okay, I was going to install 2.2 on my phone which had been previously rooted, and i seemed to have locked up the phone because i forgot to clear the cache and what not. I remember when I went to root 2.1 using sprecovery and rsd lite and what not, there was a key combo i could press to boot into sprecovery. I have a bunch of backups that i can restore from, but I cannot for the life of me remember what buttons to press to get into sprecovery. If you could help, I would appreciate it much. Thank you.
