Dear All,

I'm trying to port Ubuntu Touch for Motorola Photon Q.

I followed the deprecated porting guide and built and uploaded an image to
the phone.
The phone bootloops with my image (recovery mode works).
I checked the last_kmsg file, which contains the following:

[    4.291011,1] initrd: boot mode: ubuntu
[    4.339081,1] initrd: mounting system.img (user mode)

[    4.609400,0] waiting on pmic to shut msm down

Can someone please tell me what might be wrong with the image? And in
general, is there a troubleshooting guide somewhere?

Thanks in advance!

Regards,

Vladislav
