Qualcomm HS-USB Qloader 9800

Hey Everyone,

I am working on a Few F6 devices, trying to fix these phones. They only show Qualcomm when connected to P.C. I have attempted to reflow the devices and remove epoxy that may be preventing the flux to reach the solder points. I am wondering if anyone has or is currently working on any have been successful. Replacing motherboard is not a resolution for this case. need them fully working.

If they only show Qualcomm via USB, flash is completely wiped, that's truly bricked. What do you mean "reflow" and "solder points" ? Are you trying to do JTAG directly into the boards or something? What kit have you got there?

No Kits, Just and Air Gun and Flux. I am reflowing the board with heat and flux attempting to get the soldering points under the chips to reconnect to the board. It's worked on other devices that I have worked on.
