Tested this with Oneplus2

When in bootloader, device is not recognized, error: "The device msm8994 is not supported"

In release 0.7.4, same situation, device is properly recognized as oneplus2.

@sahirul That sounds either like the unlock of the phone did not work properly, or your flash eMMC has some troubles.

From which Android are you coming from? I suggest you try to flash stock Android 5.1: https://dl.google.com/dl/android/aosp/hammerhead-lmy48m-factory-e01ca3b7.zip - and see if that works.

@poVoq Sure, i'm open to including any and all operating systems! I opened an issue about it a while back, happy to hear your input on weather pmbootstrap should be wrapped or re-implemented: https://github.com/ubports/ubports-installer/issues/1396

Sorry for the quick iterations, here's yet another one:

Due to time constraints, we had to squeeze another minor thing in.

@NeoTheThird thank you, I will give it a try as soon as I am in front of my PC

Might be. The snap package handles udev rules (required for device access) that might cause issues when adding new devices. Could you check if another installer package, AppImage for example, sees the device?

@thilov
I tried the snap version ，same problem.
