I'm new to all this Root stuff so please don't ask me any compilicated questions, 
I first brought my HTC Desire off eBay about a year ago (June 2011).
The screen wasn't working so I brought a new screen a few months after buying the phone and then replaced it with the non-working screen.
After I put in the new screen, I 'Hard Reset' the phone using the button method and ever since that day, the phone does boot up but just stays on the HTC Logo.
I need major help guys?
