Root's Problem

[Guest Fra87]

When I have installed the rom 1.004 from, I can't see the devices with adb devices. Then I have carried out the root of my mobile phone, but in the bar notification debug usb isn't seen, seems like that there aren't permissions root, then if I click on quickboot the mobile phone crashes and that doesn't let me entry in modality recovery, all this has started when I have modified buil.prop, because I wanted unlocked the market.

How can I solve this problem?

Thanks you.....inadvance
