First, I remember that BlackBerry officially hosts firmware updates on their website. I should check if they still have the 9630 firmware there. Maybe they've moved some of their older firmware to an archive section. Alternatively, user forums like CrackBerry or XDA Developers might have community-uploaded firmware versions. I should mention these options but caution about the risks, like voiding warranties or bricking the device unless done correctly.
However, it's essential to note that downloading firmware from unofficial sources can pose risks to the device and its data. Malicious firmware can compromise the device's security, leading to data breaches or even render the device unusable. blackberry 9630 firmware link
