[Elecraft] FW Loading error

[a.yoshida]

I tried to load FW ver2.76. (previouly ver2.67)

Just after starting loading process it stops with error massage.
I do not remember what message is.
Now display shows only "MCU LD" and "TX" LED blinks.
Pushing "Power" sw does not work at all.

TX LED goes out if unpluging DC cable. But it blinks again if pluging
DC cable and plushing "Power" sw.
I tried above with unpluging RS232c cable but had sane result.

Holding shift/Lo knob and pushing "Power" sw does not work at all.

This is first experience. All FW update has been OK without error.

Any idea please.
