Things have been running stable for me since my last post - I'm using a dedicated 5v 2.5A USB micro power supply and the same SD card, along with a wired mouse, keyboard and USB controller on an unpowered hub. I've since added a nice 15mmx15mm copper heatsink for the CPU and two small aluminum heatsinks for the RAM.
I also added a power button using the header on the side of the board. I scavenged a push-button from an old DVD player that works perfectly.
I'm running a SNES emulator (Retroarch Snes9xnext core) with a graphics-heavy game under Android as a benchmark - and the CPU gets extremely hot. However, it is completely stable during the 40+ minute test run. I'm not certain if the system throttles when temperatures hit a certain threshold, but it seems to stay at full speed now that the heatsinks are in place.
In any case, things are running well now.
Glad to hear things are running more smoothly for you now, that's great.
I believe the CPU heat issue has been addressed several times on the forum. Andrew2 did some very interesting investigations into this area:

Can you link to the dedicated 2.5A power supply that you're using?

I typo'd - it's 2.1A. But there is a 2.5 listed on amazon:

I am successfully using the 2A USB charger that came with my Oneplus One.

I'm stuck on the first step, installing img file (RemixOS, Lollipop) : It don't want me to play with my new toy
Diskcheck OK
Img file OK
Startup Mode
Format to Normal OK
Burn KO
"Error" shown after "Start Burning...", after "[phoenix card_00]Burn Sucess, after few seconds after "[boot]Burn Sucess", or "[misc]Burn Sucess, while I think writing img on microSD card.

I tried so much time quitting and relaunching software, rebooting my PC, another microSD card (8 noname, 16 sandisk, 32GB lexar), another microSD card reader, or USB port (2.0, 3.0, front, back). I also try to format microSD cards with SDFormater, or cleaning them with Diskpart
Can you please help me ?

if you have 32gb(or larger) card you can try the dd image I linked here: http://forum.pine64.org/showthread.php?tid=141&pid=4056#pid4056
RE: Pine A64+ won't boot? - afr0 - 03-30-2016
janjwerner i've got the same problem
I also tried another psu (work on RPi 3) but the red led is the only thing on the board, and Lollipop/Arch-Linux IMGs.

Did you also exchange the cable between PSU and board? Or just a different PSU?

SD Formatter and Diskpart are absolutely useless (often recommended but that's just the result of people doing copy&paste from Raspberry Pi installation guides where SD Formatter is necessary for SDXC cards with 32GB or more to get them FAT formatted which is absolutely useless on any other board prior to writing an image) but you should check whether you're able to burn an image successfully. That means: Verifying the process and not blindly trusting that it should work.
Choose the slowest SD card you have and connect it to the slowest USB port available, then let one of these tools run:

And then do the same with your fastest card on an USB 3.0 port. Maybe just to realize that many USB card readers start to corrupt data after some time when they overheat (which in turn might be responsible for the errors you see from Phoenix card and the inability to boot any image since they crash at boot stage)

Follow @Andrew2 suggestion - check different PSU / cable, and test the card.
As discussed some time ago production boards have just red LED so that is completely normal.
RE: Pine A64+ won't boot? - pine.tree - 03-30-2016
Yeah, i think a lot of people are freaking out and not giving enough time for the Pine to boot, just because they see the red LED. I do think that Pine64 should have not changed the consumer version to have a red LED, that's just confusing. I saw somewhere that it can take up to 10 minutes for the OS to boot up for the first time, after that it should be much quicker.
Personally i would gather as many cables and adapters you have, and try each combination with 10 minutes running to make sure there's nothing wrong.
