How to go back to QHSUSB_DLOAD mode?

I am stuck on the red nokia screen, after succesfully flashing the msimage.mbn and the HEX.hex file, however the HEX file used was accidentaly not the correct one. I'm no longer able to return to emergency download mode, and rnd mode wont allow me to flash the mbn and proper hex file.

If I try to pass the FFU file, I'll get the following;
