Android 7.1 (PINE A64(+))

[mmmarcus]

I have been successful at getting the 6.0.1 image working. I think the issue originally was the power supply (although this was one purchased from pine64)

I am trying 7.0 or 7.1 with no luck. After some reading i may need to edit a file to enable video.

I am using a pine64 2gb (not LTS although i have an LTS also)
I have the LCD from pine64 (this worked with both a linux ver and the 6.01)
I am not using an EVO card. I used SanDisk Ultra 32 A1 UHS1, also tried a SanDisk Extreme 4k UHD, U3 V30 A1

I have been using etcher over DD.

When i plug the power in; the lcd does not display 'all winner' like 6.01. It displays nothing
on the attached HDMI monitor i can see that the center portion of the screen lightens like it wants to display... but nothing.
It stays like this indefinitely.

Any suggestions would help.  I can see that power can be an issue. From specs it seems that the SanDisk Extreme is faster the the EVO.  Has everyone whom got it working used an EVO card or just a fast A1 speed card?
