CM-5 problems, no connect to PC, update CM-5 not possible!

[ROBO-TECH]

Hello,

I assembled 18 Leg Humanoid.

1. I have connect the CM-5 to PC and go online, it works fine!
2. Download "CheckAssembly(Humanoid).bpg" all okay.
3. Download "DemoExample(Humanoid).bpg" all okay.

4. By the program BCP-Management-Robot Motion, i have Transfer
the "DemoExample(Humanoid).mtn", at this time begin the
problems with CM-5 !

Wenn turn Power on, Power Led is on, Play LED is flashing,
when pressing Mode button, all Leds go off, no function.
Turn Power off and on, no Leds no function.
(akku is full)
I Turn Power off and white 1 minute, power on and the Power Led is on.

Serial Cabel connect to CM-5 and PC, will send data or another .bpg
when clicking the Download button all Leds going off, no connect
no function.

And a update for CM-5 is not possible !

Robot Terminal, pressing and holding "#" key and CM-5 Mode button,
all Leds go off no function!

I think there is no Boot loader!

Can i update or fix the Boot loader ?

Any specially software or hardware for Repair the Bootloader ?
On the PCB "J5" with 5 pins.

Can i check in a another way the Boot loader if this correct or damaged.
Have anyone a idea.

Please, help me.

I don't think the J5 is a programming connector because here are the connections to the Mega128:

J5pin Mega128pin Function
1 11 (SCK)PB1
2 2 RXD0/(PD1)PE0
3 3 (TXD0/PD0)PE1
4 20 RESET
5 GND GND

I would expect connections to SCK, RESET, MOSI and MISO for SPI serial programming and to TCK,TMS,TD0 and TDI for JTAG programming. These connections aren't all brought out on the J5 connector. SCK and RESET are but they are no use on their own.

So I am not sure at this point what J5 is for.
