Bold 9900 Boot Freeze

Hello, I'm wondering if someone can help me.

I've bought a BlackBerry Bold 9900 - It was an A Class refurbished model.

Now, I come to turn it on and it freezes between E and Y on blackbErrY...

I've done some research and I've tried ;

Boot in safe mode - Failed (Freezes same place)
Reload OS - Failed (App Loader failing to reconnect)
Leave a while without battery in - Failed (Freezes in same place on boot up)

I'm wondering if this is a hardware issue, I can send it back, its just a gift for christmas and would rather not if i can fix it myself. - I've deleted Vendor file before reloading OS, and ive left for well over an hour to boot up with still failures to reconnect

It says - "Reconnecting to JVM" - Then fails to reconnect. (I also have the latest Java on my computer.)

These are the files and systems im using;

Windows Based Computer
BlackBerry Handheld Software v7.1.0.2930 (All Languages)
Blackberry Desktop Manager 7.1

If it comes to it I will have to send it back and buy another for the meantime, although any help or suggestions would be greatfully appreciated.

Thanks, Wayne x
