Evo stuck on screen I've never seen before! Please Help

The Short: Phone stuck on black screen with a picture of a phone in the middle with a red exclamation point in a triangle.

The Details: My phone started acting funny today. Apps wouldn't work, the Market was acting funny, not installing anything. Tonight it started getting slow and so I started deleting apps that I don't use anymore. I noticed that my battery drained about 30% in about 3 minutes. So I turned my phone off, and turned it back on. It would get to the 4G splash screen and then reset again, again and again. I've had this infinite boot loop happen before so I figured I would bite the bullet and reset my phone to factory settings. I took the battery out, put it back in, held down the volume down button and turned it on. I was presented with the options of fastboot, recovery, clear storage, etc. I was on the bus and forgot which one i picked last time, so I figured i would just try "recovery." It started to reset, and then all of a sudden went black except for a picture of a phone in the middle of the screen with a red exclamation point in a triangle over it. I took the battery out and tried to do this again, but now I can't even get in to those recovery options, it just goes right to that black screen with the phone and triangle. Anyone out there know how to fix this? At this point, I don't care about my info on my phone, I just need my phone to be functional tomorrow. Thanks.

Easy, while youre in the recovery screen with the picture of the phone and the triangle, press volume down (or up i forget) and it will give you options. One of them is to reboot. Hit that one.

Seems like youre having problems with bootloops? Have you tried a factory reset?

Thanks, I reset it to factory settings and its working again. And thank goodness none of my pictures were lost. That was my only concern. I really need to sync my photos/contacts more often.

Your sd card won't get erased unless you specifically format it, so generally your sd card stuff is safe.

Glad a could fix you up man.

Help! Please help!

i got the same screen (black w/ pic of phone & red exclamation mark) after following root instructions listed here: http://forum.androidcentral.com/htc-evo-4g-roms-hacks/17769-how-windows-root-your-htc-evo-install-clockwork-recovery.html every time i get into the bootloader and it loads the PC36IMG it says it fails and when i reboot, i can't even get into the OS... what the hell happened and how can i fix it?

Go to the hacks section, run the ruu, and use the new method for newer hboots.

i tried running an RUU but my computer won't even show the phone as connected anymore...

Do you have USB debugging enabled on the phone? Or are you trying the to run the RUU from your bootloader?

i had USB debugging enabled but the phone wouldn't get off the "black screen w/ exclamation point of death" and into the OS for me to make any changes. i wasn't even aware you could run an RUU from the bootloader! i think my wife is taking my phone in to best buy today to get it replaced. i wish i had more time to try to fix this on my own but alas...

also, i wish i had known there were multiple hboot versions or that this would have happened based on newer software. i feel like the post gbhil made is somewhat obsolete now because i got stuck at step 3 when the batch file wouldn't restart the phone!

i hate sounding like a noob but i thought i knew more than this...
