HOST -> DEV: HELLO (0x01, ver=2, mode=0x01) DEV -> HOST: HELLO_RESP (0x02, status=0, ver=2) HOST -> DEV: READ_MEMORY (0x10, addr=0x80000000, len=0x1000) DEV -> HOST: DATA (0x12, len=0x1000, <binary>) HOST -> DEV: DONE (0x04)
The process involves a "Hello" handshake where the device provides a memory address table. The QPST Configuration software automatically detects this connection and initiates the dump collection. Unlike standard file transfers, this is a raw snapshot of the system state, including both user and kernel mode memory, though it typically excludes regions protected by the Trusted Execution Environment (TEE) . Utility in Post-Crash Analysis
The secondary responder. Once Sahara successfully injects the programmer file into the RAM, Sahara terminates and hands control over to Firehose. Firehose interacts directly with the storage disk (eMMC or UFS), allowing users to read, write, partition, or wipe the device memory. Conclusion

Upgrade to the latest version of the QPST Suite, or downgrade to an older, specific version if you are working on a legacy device (e.g., QPST v2.7.496). 3. Sahara Read/Write Timeout
To interact with a device in Sahara mode, you need the QPST tool suite installed on a Windows PC. Step 1: Detect the Device Connect the device via USB to the PC.
Choose an output directory on your local hard drive where the massive memory dump files will be saved. Step 5: Start the Dump
