: The 2021 Poco X3 Pro is notorious in the tech community for motherboard reliability issues related to the CPU soldering (reballing issues) and Power Management IC (PMIC). If your phone died suddenly while charging or gaming and does not show up as 9008 mode at all, it is likely a permanent hardware failure , not a software brick. A firehose file cannot fix cracked motherboard solder joints.

: This happens if the patched Firehose version doesn't perfectly match your chipset revision or if the Mi Flash Tool configuration is wrong. Ensure you downloaded a file specifically tagged for the Snapdragon 860 (vayu).

Until then, remember to approach any flashing procedure with caution, and always back up your data. The Poco X3 Pro is a resilient device, and with careful effort, it can often be brought back from a bricked state.
