An Autoloader is essentially a script wrapped around the RIM Loader Utility (Loader.exe).
| Feature | Autoloader | BlackBerry Desktop Software | |---------|------------|-----------------------------| | Requires OS boot | No | Yes (device must boot) | | Wipes user data | Yes | Optional | | Flashes radio + bootloader | Yes | No (only OS update) | | Recovery from 507 error | Yes | No | | Carrier branding preserved? | Depends on autoloader | Yes | | Speed | Fast (5 min) | Slow (20+ min) |
Before you download random EXE files from the internet, you must understand the naming convention. A legitimate BlackBerry 9900 autoloader file typically looks like this:
9900_7.1.0.1098_7.1.0.523_P6.15.zip
BlackBerry 9900 uses a secure boot chain:
Autoloaders are signed by BlackBerry (RIM) – third-party autoloaders (e.g., from leaks) are often repackaged but must retain original signed partitions to flash successfully.
The 9900 supports two low-level modes:
| Mode | Activation | Use | |------|------------|-----| | Device Mode | Normal boot, USB connected | High-level OS updates via BlackBerry Desktop Software. | | Engineering / Dead Mode | Device off, battery in, USB connected | Autoloader flashing; no OS required. |
When the device is in 507 error state (missing OS), it automatically waits for an autoloader.
