Can't login to Blackberry ID with Torch 9860

I am trying to recover photos and videos from my old Torch 9860, and I am having trouble logging in to my Blackberry ID, which is apparently crucial to getting in and operating the phone. When I start the phone up, i am required to log in to my Blackberry ID, but when I put in the correct email address and password (I know this combination is correct as I have logged in several times on my computer), it denies me access and I have one less of my ten attempts to get the email and password right.

When I try to click the "Forgot Password?" link, it comes up with the message "unable to update Blackberry ID account information while offline". Now, if I can't turn on wi-fi or mobile data to get online, how then am I to go about not only changing the password, but logging in all together? I am worried because if it's not connected to the internet, how does it even verify whether or not the email I'm logging in with is valid or not?

I have also tried connecting the phone to my computer and backing it up using Blackberry desktop software, but the computer won't recognise it.

try Hard reset to your Device
