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-WRTI have a Japanese digital media player from NTT called HB-1000 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.lk is used during the boot processhttps://github.com/littlekernel/lkSpecs: Telechips TCC8930 Dual ARM Cortex A9 @ 1.2GHzARMv7-A4GB NAND flash1GB DDR3-800Mhz RAMLAN 1000Base-THDMIUSB 2.0 (x2)SD card slotWi-Fi 802.11nBluetooth 4.0A reset and WPS buttonGreen blinky LED lights (very important)The circuitboard is manufactured by OKII 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?Thanks!!
