Since then it is not listed in devices /dev/ directory. Also $ fwupdmgr get-devices does not list quectel modem. I am sure modem needs to be booted into EDL mode as in regular PP by shorting test points on the board, but on the pro i have no idea how to do that, because they are not marked.I opened a ticket in pine64 support. They instructed me to perform hardware test in their android build, which i did. Exported a test result and sent them. Second day still no answer as of yet. I will update of the progress, but i am actually very motivated to hear any suggestions up untill then since this can happen to anyone and would really be awesome to find a recovery solution.

Here is my output of 'cd /dev/' and lsusb
