The 9900 was released in 2011. Over-the-air updates were slow and prone to corruption. RIM (Research In Motion) created autoloaders for carriers and repair centers. These files bypass the device’s operating system entirely—they write directly to the NAND flash memory via a low-level USB boot protocol. Essentially, you are taking the device back to the moment it left the factory.
When you download a file named something like 9900_7.1.0.1098_P5.1.0.604.exe, here is what those numbers mean for the 9900: Blackberry 9900 Autoloader Flash File

The BlackBerry Bold 9900 is notorious for a specific hardware flaw: eMMC (embedded MultiMediaCard) wear. The internal memory chips in the 9900 have a limited number of write cycles. Over a decade of use, many 9900s develop "bad sectors."
When the 9900 crashes to a white screen, it is often because the OS tried to read a corrupted sector. Standard wiping via the device's security wipe feature won't fix physical bad sectors—but an autoloader flash file will. The autoloader performs a low-level format of the user partition before writing the new OS, forcing the eMMC controller to map out defective blocks.
