Done. Indeed, the cells seem to fit more snuggly.
Still no luck. All I get is a faint flash of the blue light, three times, on the FTDI adapter, the the "Unable to Connect" dialogue. The behaviour is exactly the same as if I hit "Send File" and there is no calc connected at all. It's as though the calc is just dead on the end of that cable.
Still able to flash a working unit with the same cable and set up, so those bits are fine.
Obviously something intrinsic to the unit. Indeed, I assumed the aborted flashing last night was due to dead batteries. But when I try the suspect cells in a working unit, BATT gives me 2.9 or 3. I have done successful flashes in the past with BATT returning as low as 2.8, if I work fast.
Assuming mechanical problems in the calc at the moment--perhaps a short or something involving the power supply. It isn't that terribly critical--my other two units work beautifully--but it does bug me when something doesn't work. I only paid $40 for the original 30b and a few bucks for Eric's overlay so the loss isn't huge. Still, I may consider sending the unit to one of the WP34S's Canadian friends (Neil in Ottawa, perhaps) to see if anyone can help.
If there are any other diagnostic ideas, I am open.
Where does one get the 3.2 manual? I am seeing only the 3.1 manual in the Sourceforge main download AND in the doc subdirectory of the most up-to-date Code.
PS. I just remembered that when the aborted flash failed it ended with a dialogue that said something about "time out" and "ack".
