Msm tool is posted on XDA op9p but you could try to use fastboot ROM(if it's out there yet) what I did with my op8p was flashing havoc os that brought it back to life maybe you can do that to when you have the full ota update and unpacked with payload dumper
I was to try that with my op8p from havoc os because I can't use msm tool on my PC that thing is s decade old a d doesn't detect my phone
So I just received the phone today and as I always like to do with my new phones I downloaded the latest full ota, installed it through local upgrade and when I pressed reboot the phone rebooted normally.
I went an pressed reboot to recovery and boom the phone just died, no recovery it goes to QUALCOMM crash dump and I am able to boot into bootloader but OEM unlock is still off in the developers options, cant unlock boot loader, cant flash anything in fastboot and there are no MSM tools.
Anyone have any ideas??
Be careful I was on stock rom flashed with stock latest rom with locked bootloader and no funny business and the phone just dead.
I attempted that however OEM Unlock is not turned on in developer settings and fastboot --set-active just returns an error, something like Commands not allowed.
After 16 hours I finally got my remote session, it took almost 2 hours and they attempted to flash the wrong files on to my device, thank god MSM verifies that first. Then after the tech says "I apologize, my bad, I should have checked that first, we will try again in about 24 hours."
That was a bit ridiculous and if a supervisor isn't able to get it fixed soon, I'm just gonna return it and take my business somewhere else.
