what power supply are you using (voltage and amps)?
what max resolution does your tv support (1080p or 720p)?
what brand, size & class is your microsd card?
did you plug in the ethernet cable?
If you like my work be sure to check out my site or wish to donate to the cause

easiest way to find out whether your pine is doing anything is to hook up a serial console to pins 7,8,9 (9 GND) on the EXP connector. note staggered numbering. http://elinux.org/Pine64#Serial_Console I used my ch340g (the one I bought for ESP8266 development, so it has that kind of connector... I just used some male to female jumpers) at 115200. figured out that it was booting, so I let it finish doing the ext4 format thing and then used reboot -p on the serial console to shut down.

in my case the problem was that I only had 1 monitor that would properly support 1080p. you might have some other problem. I took my pine out to the TV after it didn't work with 2 monitors, that worked. So I made space for my other fancy-pants monitor (it was cheap with 3 dead pixels but it's a samsung 25.5 IPS... main one is a burned-in viewsonic 25.5 IPS) Smile and lo and behold, it worked.

if you interrupted the (lengthy) format process on first boot then you need to start again. the serial console is a way you can keep an eye on the first boot process. an absolute cheapest serial interface should work fine.

I also bought the official power supply. your lg g2 charger might not actually be capable providing 1A, let alone 1.8A. Without an ammeter (You can get a USB power meter for about $5, but you will need wacky cables to use it in this application) it's hard to know. The Pi is also very sensitive to power supplies.

Hi,

My TV does'nt support only 1080p24 and 25Hz max.
720P all refreshs is ok and 480 720p too.

But how to boot on my TV ?

Can I change the display resolution without boot on my TV ? With a USB too TTL ?

Thanks

We plan to release the new Android build on this week and default the display out to 720P. We are working on this build for a while and hopefully out on this week.
