1. Loaded Firehose for SDM845 (prog_emmc_firehose_845_ddr.elf).
2. Issued a Sahara memory dump of the first 100MB (containing bootloader, modem, and persist).
3. Compared the dump to a known-good dump from another device.
4. Found that the abl (Android Bootloader) partition was all zeros.
5. Flashed a clean abl image back into the memory range (offset 0xE00000).
6. Device booted into fastboot immediately.

Without the Sahara dump capability, the device would have been e-waste. Loaded Firehose for SDM845 ( prog_emmc_firehose_845_ddr
