The 6 most common reasons why Pine64 won't boot

[tllim]

Hello! I have problems with my pine64 also. My conf:
2 GB with BT+Wifi module installed
5V 2A adapter (tried several different)
NO Ethernet cable connected.
Direct HDMI to Phillips TV 1920 x 1080
64 GB SDXC

I was very-very careful about static, so the board is ok.

What do I have. I've tried to installed both Android (all 3 images) and Remix OS using PhoenixCard.
RemixOS has been installed (it was not easy, but installed at the end). But when it boots up it works EXTREMELY slow (reacts in 10-15 secs after pushing "start"-button), shows black screen, error messages (ex "Process system isn't responding. Do you want to close it?") and reboots.
Thereafter it may boot or not (depands on I have no idea what).
Android OS did not boot up at all. First it shows up "Powered by Android"-screen, then just PINE64 logo and that's it.

Any ideas? :-)

Looks like microSD card access issue. I have similar experience using on SanDisk 64GB microSD card, and the problem goes away when switch to other card.
