I've tried to update from ANDROID 7 HMD-2.0.0 2016-11-17.184554 via rear pin push as well as flashing with the recovery files on usb to the following firmware with no luck at all. the first Android logo comes up and then I get the red exclamation mark again.
HMD-2.0.0 2016-11-17.181855
HMD-2.0.3 2017-04-12.095905
Any suggestions? Seems stuck on that base firmware.
