Hello, I need help.

I installed OS 5.0 on my blackberry bold 9000 and it worked.
But now im getting: "reload software 507". I tried to reinstall os 5.0 and 4.6, but when the apploader reaches " connecting to boot ROM " the phone just keeps restarting and no connection is done.

I can't install the OS! any ideas? i tried to install it without the battery but my pc won't see the blackberry.

Hey,
uninstall any previous OS make sure 5.0 is successfully installed on your PC.
if your pc is not reading the device try using different pc and let the drivers install completely.
Use BBSAK to make it easier on yourself (wiping, loading, etc..)
I had the same issue installing OS6 on my gf's bold 9700. the only way i got it to work was by using a different pc.
i tried everything! even now it's worse. I tried to remove the cord and the battery while connectiong to boot rom (some post said that) and now my blackberry is just blinking red and wont display anything..
