Moved you to where the help is....

 

It looks like your friend of a friend has RSD Lite working correctly because your friend of a friend is flashing all these various files.

It sounds like your friend of a friend still wants to root their phone. Can you ask your friend to ask his friend which rom he wants on his phone?

If the phone is not booting up there is a good chance your friend of a friend's phone has a low battery and your friend of a friend should put it on the wall charger until it will boot up.

To get back to stock:

Use RSD Lite flash the stock 2.01 sbf file

Then use RSD lite to flash the SPRecovery sbf file before the phone updates to android 2.2 (if it does that's ok, your friend's friend still can flash sprecovery at that point)

Next you want to tell your friend to tell his friend to to make a backup of his phone via SPRecovery's Advanced Nandroid backup feature.

And finally, your friend's friend can flash the rom he wants.

 

Been a long day, I'm getting punchy.

One of 2 things is occurring. The battery is low, or something went wrong with the flash to the rom. I'd recommend the first link in my signature and follow those steps if the phone will boot. Use the Froyo rom. Wipe cache/data a couple of times before applying the rom. No wipe of data/cache and funky things happen when moving from one rom type to another.
