Hi, all.
I tried to upgraded my M92 from Firmware ver. 1.7 to 1.8(recent one: 20121113).
My Memory Usage was 183/245MB and Flash Usage was 3130/3297MB.
I know how to upgrade firmware
(Copy firmware ZIP file to SD card and press ON/OFF button holding joystick/OK button until "Software update request deteced, checking updates... " message
comes up. )
But the thing is, NO Upgrade done. I tried 5 times the same way.
It took about 10 min every times. But last time, the
"No update found booting device..." was came out after
"Software update request deteced, checking updates... " message gone.
I tried to turn on M92 after pressing reset button on the back of M92.
If I press just Power button, it goes like.

If I press Power+OK joystick both, it goes like.

In both, the blue light was on forever and M92 freeze.
Battery was full. (I linked M92 to PC via USB port.)
I think it must be a software glitch since everything works fine in normal use.
(No hardware thing for sure.)
I would be happy to hear some FACTORY reset or problem solving way.
Thanks in advance.
