I'm new to this site, and new to the whole rooting of the HTC Evo thing. Total newbie. I hope you can help me.
I am trying to change the ROM in my phone with another from the xda developers site and got a tutorial online on how to do this using the Recovery in the bootloader. But when I go to bootloader and click on recovery I get a black screen with a picture of a phone and a big red triangle with an exclamation mark.... What did I do wrong and how can I set it right, do you know?
No, i know i'm not rooted. But I did the upgrade to 2.3.3 when it came out - is there any way to go back to the older version?
Why am i getting the warning sign?
Right now there isn't a way to go back to 2.2 or root 2.3.3, it's getting closer. You are getting that warning because that is the stock recovery. You can't flash from that. You need a custom recovery (but need to be rooted first) like Amon_RA or Clockworkmod.
