| Problem | Developer Fix | |---------|----------------| | Autoloader doesn't detect device | Install Qualcomm HS-USB QDLoader driver (use zadig or legacy BlackBerry USB drivers) | | Flashing stops at 98% | Re-run; if persistent, flash only core OS (extract and use mfgtool manually) | | After flash – stuck on BlackBerry logo | Boot into (volume up+down during boot) and wipe via autoloader -wipe | | Cannot sideload .bar files | Use chrome+playbook app manager or barry (Linux) + ensure debug token is installed via blackberry-deploy | | Radio (cellular) not working | You flashed a dev OS without radio firmware — flash a full production autoloader first, then dev OS over it (without radio) |

Regular consumer autoloaders wipe and restore the device to its commercial state, which forces the user through the setup wizard—a step that can get stuck due to the decommissioned BlackBerry infrastructure.
