Weird issue happened to my Evo

[groovdafied]

Luckily I backed up my phone before I did this "update" that was pushed to my phone. It said it was a needed software update that automatically showed up on my phone, I let it run then my screen got stuck with an yellow exclamation point with the android robot. I assumed this was bad and that it totally bricked, so I restored back to my latest backup.

Does anybody know or recommend anything about this update? I can't tell you exactly what it is, because I don't remember...but it was something like 3.23.1.xxxx

Thanks!
