No boot CFC (bootloader) NightHawk X10 R9000

Hi, everyone! Nearly i bought (secondhand) wi-fi router Nighthawk X10. When i power on, it light power, WAN(without insert internet cabel), guest wi-fi, usb 3.0 (2 led), wi-fi, wps, and light 6 lan led, then light 5 lan led (light off 6 lan led).....Then all lan led light orange, after it light off in all lan led. And that is all. Not responding router. I open router case, and find uart pins. After i open console terminal Putty, and power up router. I see only "CCCCCCCCCCCCCCCC" ........... After i think may by it com speed wrong, but no. What is it? Broken bootloader? Or CPU?

This metod working if router have good (not corrupted) bootloader CFC!!! If in UART connection in console terminal have life, then it metod will work!!! In my case no life of console terminal only "CCCCCCCCCCCCCCCCC". I think it or corrupted CPU or bootloader. But i do not no where bootloader save in nandflash or in CPU or in eprom flash.

   I know nothing about the low-level soft/firmware in these devices,
but are you looking at an XMODEM/YMODEM request to send a file
(repeated)?

      http://textfiles.com/programming/ymodem.txt

      [...]
      As in the case of single a file, transfer, the receiver initiates
      batch file transmission by sending a "C" character (for CRC-16).
      [...]

   Even if that's true, exactly what you should sent to it is a myatery
to me.
