BIGBIG WON Blitz 2 Gaming Controller（TMR Joysticks Model）

I love the mechanical buttons and dpad. It's very responsive. Slightly big, but no big deal. Good gyro.

BIGBIG WON Blitz 2 Gaming Controller（TMR Joysticks Model）

I bought the Blitz2 TMR (the 2000Hz version) and it was working perfectly until I tried to update the firmware using the BigBigWon Assistant.
The update failed mid-process and the controller instantly bricked.

Now the controller:

Only enters bootloader/recovery mode

Appears on Windows as VID_413D & PID_2104

Shows no LEDs, no power, no normal mode

BUpgrade says “successful” but the controller remains bricked

Seems like the software pushed normal Blitz2 firmware to a TMR model, which caused the brick

This is clearly a firmware mismatch issue, not a hardware defect.

I urgently need:

👉 Blitz2 TMR V3100 firmware (.bup)
or
👉 TMR recovery firmware

If anyone has the TMR firmware stored in their BUpgrade / First Aid Kit folder, please share it.
This controller is fully recoverable — it just needs the correct firmware.

Any help would be greatly appreciated!

Amazing

The blitz 2 has been a great controller,very responsive and fast. Thank you.
