A: No. Hard-bricked devices show no signs of life (no backlight, no vibration). Your device still enters the bootloader, which means it is 99% recoverable via software fixes.
: Windows often treats "Fastboot Mode" and "Fastbootd Mode" as two different devices, requiring you to install drivers for each mode separately.
High-quality data cables are required; charging-only cables will fail.
You are attempting to flash files intended for a different model or software version. Step-by-Step Fixes 1. Update Android SDK Platform Tools
If locked, unlock it (note: this wipes data): : Windows often treats "Fastboot Mode" and "Fastbootd
it usually means the transition from the bootloader to "fastbootd" (userspace fastboot) is blocked. This often happens during firmware flashes or custom ROM installations when the device cannot find the necessary partitions to enter this specialized recovery state. 1. Update or Reinstall Fastboot Drivers
, as third-party cables may lack the data integrity required for partition flashing. 4. Flash a Complete Fastboot ROM

If you can still enter (Stage 1), you may be able to fix the missing components.
Handles low-level partitions like boot , recovery , vbmeta , and dtbo .
