For the Redmi Note 9 Pro specifically:
- The Snapdragon 720G chipset communicates via Qualcomm's proprietary EDL channel using Firehose programmer files
- Standard Android ADB tools cannot access partition-level operations without chipset-specific support
- Account service operations on MIUI-based Qualcomm devices require tools that understand both Qualcomm's hardware layer and Xiaomi's software structure
This is why a dedicated Qualcomm tool like Best Flash Tool by Boss V1.7 is relevant for workshops that regularly service this device category. Using the wrong tool for the chipset not only fails to complete the job — it can leave the device in a worse state than before.
