Before diving into the patched version, let’s understand the terminology.

A Firehose file (also known as a programmer or loader file) is a proprietary binary blob used by Qualcomm chipsets to communicate with the device when it is in Emergency Download (EDL) Mode (9008 mode). When your phone is hard-bricked (no display, no recovery, no fastboot), EDL mode is the only interface left. | File Name | Source | Status |

The official Firehose file allows authorized Xiaomi service centers to reflash the device. However, for security reasons, Xiaomi started signature checking on these files. If you try to use an unauthorized Firehose file, the phone will reject the connection with a "Sahara fail" or "Firehose negotiation failed" error.

Alternative: EDL cable (DIY or bought) that shorts D+ and D- on connect. Verify before use
