FAILED (remote: 51 partition update fail)
finished. total time: 177.853s

Thereafter i tried to reboot it, and it went straight into the HTC Logo with 4 warning triangles in each corner, like this: http://i.imgur.com/Qzo3Nvi.jpg

So yes it turns on but if i try to get into the bootloader the screen phone just turns off and comes right back onto this screen.

Thank you in advance!
