    Hi, I would like to unlock my blackberry classic SQC100-4, but the carrier is unknown. I know my PRD number, could that help?

    Thanks

    There might be a way, if you have a Windows PC.

    1) Download CFP and save it somewhere: https://mega.nz/#!jUkFWYSB!PrVDI1YNT...VAjMcJJ8gecCeY

    2) Open a command prompt/PowerShell window in the same folder as the exe file (https://www.howtogeek.com/howto/wind...ht-click-menu/)

    3) In the window, type "cfp-3.10.0.57.exe info" (add a .\ to the beginning if you're in PowerShell). You should see it wait at "Connecting to Bootrom:".

    4) With the Classic turned off, plug it into the PC running CFP, then turn it on.

    5) If it works, then the LED on the phone should turn green, a progress bar pop up in the window ("Uploading RAM Image"), and then a bunch of info on the screen.

    6) Post the "Branding" item if any. ECIDs are how BlackBerry maps carriers.

    With any luck the ECID that's in there corresponds to a known ECID for a carrier. That it's a SQC100-4 narrows it down to the Americas anyway, if not just North America.
