Were you s-on and SuperCID, and did you try to run a Jellybean RUU? If so, that is a known brick situation. QHSUSB_DLOAD means you have a true brick and need JTAG as timmaaa said.
If S-on and superCID (plus JB RUU) and you flashed a ROM for the ENDEAVORU, that is a lot of mistakes caused by lack of research and lack of care while modding the phone. Again, like timmaaa I recommend more reading and understanding before messing with this or any phone.
