If your SOM board does not enter fast bootfastboot, then most likely its bootloader is corrupted. Re-flashing the bootloader may be able to revive the board. Unfortunately, you can't re-flash your bootloader on your own since the process requires some Qualcomm proprietary tools. The tools are proprietary because the Snapdragon processor security requirements allow only a trusted source to re-flash the bootloader.

Please note that there is no assurance that re-flashing the bootloader will revive the board. If re-flashing does not revive the board, we do not attempt any other repair. You will be required to pay the fee of US $80 only if the Devkit is recovered, or you want the non-recovered Devkit SOM on your DevKit/HDK/ADP to be shipped back.
