Anyone want to help out a noob? (excuse my incorrect terminology/ knowledge) I am venturing into unknown territory. The only experience I have is rooting/flashing firmware on my phone and installing OpenWrt/DD-WRT
I have a Japanese digital media player from NTT called HB-1000 光BOX＋ I want to install OSMC (https://osmc.tv/) or something...anything that's not what is on there now.
The media player is running Android 4.2.2, I think. I can access the GUI and open some preinstalled apps but in the settings some options aren't available (like developer options). I connected the device to my router and did a port scan. I couldn't find the SSH/FTP/Telnet ports open.
NTT's website indicates that the firmware can be upgraded when the player is connected to the internet. Maybe I can use Wireshark to help me figure out what's going on during a firmware update. NTT's website states that downloaded files can't be saved to SD card or USB.

- Telechips TCC8930 Dual ARM Cortex A9 @ 1.2GHz ARMv7-A
- 4GB NAND flash
- 1GB DDR3-800Mhz RAM
- LAN 1000Base-T
- USB 2.0 (x2)
- SD card slot
- Wi-Fi 802.11n
- Bluetooth 4.0
- A reset and WPS button
- Green blinky LED lights (very important)
The circuit board is manufactured by OKI.
I found some software from the chip manufacturer (I'll add link)
I also found a website talking about a leaked Android SDK (I'll add link)
I've managed to connect a (UART/TTY to USB) device to some debug or serial connector ports. There are 14 "holes" and I managed to connect to the correct ones to see something when I use Minicom on my Ubuntu 14.04 computer. I don't see any sort of command line. If I hit a key on my keyboard, the media player reboots.
I can provide some pics of the circuit board and my terminal screen upon request.
Can anyone help or guide me to a better place for my question or somewhere I can learn about what's going on inside when I turn the power on?
