PinePhone Pro Explorer's edition Qualcomm modem recovery
#1
Hi guys,

i really need help on my PPPro. I was recently trying to update my modem's firmware using gnome-firmware app using this instruction in the video "4 of 5": https://forum.pine64.org/showthread.php?tid=18209
Update failed to install, and now i ended up with non-bootable modem. I searched the PineWiki and found this emergency procedure designed to boot modem in to EDL mode by shorting the test points on the PinePhone, but when i removed the back cover i only found there is no simmilar pins, or at least i don't know which ones to use on my the explorerss edition phone. Also i used this Hardware test build from here: https://wiki.pine64.org/wiki/PinePhone_P...e_Checking 
and test fails for sim card. Also in Arch build it is not listed as /dev/ttyUSB2 or any ttyUSB. Seems it is bricked, and i need to enter EDL mode somehow. Is there any hope to revive the modem?
