Then MSMtool program already running, it just detect it and do all for you.
The culprit was, you have to install the driver once in Qualcomm Crashdump mode connexeted to PC, then unplug it, swithch the phone off, launch the MSMtool, hold the volume up on the phone and at the same time just plug it to PC. I managed to fix my Op6t with Windows ( yeah, unfortunately not Linux. I'll give it another shot and then just repair shop, I guess. So many versions of MSM tool, so many versions of drivers to try. I might try again to use MSM tool, but since I don't use Windows, it's rather a pain to do it. Never happened to me with any other phone, well, not in such a level that I can't fix it myself.
I was flashing TWRP recovery and I already had UT on it.
