Help tv box does not boot

Hello,

I have device based on Allwinner A20, google play listed it as "BBA22". Here is the view - http://i.ebayimg.com/00/s/ODAwWDgwMA==/z/yy8AAOSwrx5UVykv/$_57.JPG
Device have root access. This device does not have power button, so I installed "holo reboot" app - https://play.google.com/store/apps/details?id=com.scartech.holoreboot - it works ok with items "reboot" and "power off". Once I tried "reboot bootloader" item... Device rebooted and hang on displaying android logo. On normal boot android logo displays few seconds and booting continues. But now it display android logo forever. ((

I found small hole on device side and micro button inside it. I pressed this button and attached power cord. Device show progess bar, which completes in few minutes. (I guess it restore factory defaults, or so). But it does not help - it still hang on logo.

Also, device have only "regular" usb ports like on PC, and not have mini/micro usb ports to connect it to PC, so I don't know how to connect it to PC.

Any ideas?
 
Solved, I attached serial-to-usb adapter to main board and got terminal i/o, pressed Ctrl-C to enter into loader menu, and issue "reset" command. Then tv box boot normally.
