How to I reboot when i cannot connect with my computer because of error 507

I bought an old Blackberry 9790 Bold a couple of weeks ago. Yesterday I wanted to charge it on my macbook and suddently my software started to do some updating, which has not worked before. My big problem is that every time I try to turn on my phone I get "Error 507". I have tried to download the desktop software on a windows computer, but it will not connect with my phone. I do not want to update my phone. I like it a little old school. I just want to do a fabric reset.

You don't need to reboot, you need to reload the OS as it's become corrupted.

When you connect you phone to your mac or pc, does the desktop software see it? Can you do a Factory Reset? If not you need to reload it manually >>https://forums.crackberry.com/showth...l=1#post281396
