tried upgrading to 5.x with mac desktop manager

i was on 4.6xxx and saw this post

h t t p : / / c r a c k b e r r y . c o m / i n s t a l l i n g - b l a c k b e r r y - h y b r i d - o r - b e t a - o s - m a c - d e s k t o p - m a n a g e r
(spaced out because i have <10 post here)

so i figured it wouldnt be that hard... and it wasnt except for the fact that my phone doesnt work.

i turn it on and i get the new loading bar, then i get the wizard on how to use the trackball, hit continue then it shows an error message "java.lang.error blah blah" so i press the only option and then, a white screen that says the OS version at the top then a list of applications ( i cant launch anything, and i cant get out of this screen)

desktop manager prompts me to downgrade and it almost does but then it says device was disconnected and i get the same thing, im in a loop here.

please please please say this is common and theres an easy fix

Pull your battery out, wait for 20 secs then reinsert and wait for your device to reboot.

If this doesn't cure your problem, then repost your question here Beta OS Forum
