Xiaomi 12 (cupid) Qualcomm SM8450 Loader File – No Auth

Free download for the Xiaomi 12 EDL Loader. This original Firehose file is compatible with QFIL, UnlockTool, and Chimera for communicating with the device’s UFS 3.1 storage.

The Xiaomi 12 (Codename: cupid) is a compact flagship device powered by the Qualcomm Snapdragon 8 Gen 1 (SM8450). However, incorrect flashing, system updates, or software corruption can lead to a “Hard Brick,” where the device is only detected as Qualcomm HS-USB QDLoader 9008. To revive it, you need the specific Firehose Loader (Programmer) file tailored for the SM8450 platform.

• Hydra Tool
• Miflash Pro (Requires Xiaomi Auth Account)

How to Use Firehose Loader

2. Open Flashing Tool: Launch your preferred professional tool (e.g., UnlockTool).
3. Select Model: Search for “Xiaomi 12” or “cupid”.
4. Load Custom Loader: If the tool does not auto-detect the loader, manually select the prog_firehose_ddr_cupid.elf file in the “Custom Programmer” field.
5. Connect Device: Boot your Xiaomi 12 into EDL Mode. (Note: This usually requires shorting Test Points on the motherboard).
6. Execute Repair: Click Flash or Factory Reset to begin the unbricking process.

⚠️ DISCLAIMER: Advanced Chipset Warning
The Xiaomi 12 uses the Snapdragon 8 Gen 1 (SM8450), which has strict security protections. Using an incorrect or old Firehose file can permanently destroy the UFS storage. Ensure you are using the specific loader for cupid. If you do not have a professional tool or Auth account, proceed with extreme caution.
