Firmware Change Update On Blackberry 9790 Bold Work < QUICK — 2025 >

The process mandated a full backup via BlackBerry Link, disabling of the password keeper, and, crucially, a battery charge above 70%.

This fragility instilled a culture of caution; many users would wait weeks after a release to ensure no fatal bugs existed.
