Anyways, we need to make sure you have a custom recovery and if so which one. When you said you made a backup on your backup root, how did you do that? More specifically was it a nandroid backup? A nandroid backup is like setting a restore point on your pc, however it is done while your phone is booted into recovery.
To manually boot your phone into recovery, slide open the keyboard with the phone off, then press and hold the 'x' key on the keyboard while you power the phone on. Then give me a description of what you see on the screen. It should be different than what you usually see. If it isn't try again.
Now if your power button is broken, to turn your phone off, pull the battery for a few seconds, then replace it. Slide out the keyboard and hold the 'x' key and plug the power cord into your phone while keeping the 'x' key pressed until your phone powers all the way up. If it boots into your regular system, do it over as you might not have kept the 'x' key depressed fully.
Let me know what you see, stock recovery is a triangle with a red cirle around it (or something like that, I haven't seem stock in years), custom recovery's will have text on the screen, if you get that tell me the color of the text and what it says at the very top.
Whew. Hope that's enough detail and info for this part.
