    My lumia 640 XL bricked when I tried to upgrade to the preview builds. There is no response whatsoever even after pressing volume down + power. When connected to WPRT and use the emergency flash tool, it downloads the packagae but results in operation failed. So next I tried using the THOR2 tool from the WPRT. After generating the GPT0 and GPT1 files, I am stuck with the HEX file. Where can i get the HEX for lumia 640 XL or how to generate them manually with the RKH generated using the THOR2 ??

    I believe your only chance is to try it with the latest Windows Device Recovery tool. It recovered a L520 for me that would not boot at all after a failed W10M update. The next step is to contact MS Support (Lumia Help) to see what can be done.
