Micro820 Failed Downloads lead to a bricked unit

its already scheduled to be sent back to our dealer under a warranty, they took care of it last time.
This was using verion 4 or 5 of CCW so it was several years ago. I could download to a PLC and brick them just by downloading. The only way to get it back was controlflash. My apprentice never had a problem bricking one. The exact same program, i could brick it and his would work. The difference was the button we used to download to the controller. I used the dropdown menu and he used the direct button. Everytime it made a difference. The AB distributor didn't believe me until we showed him over and over with his PLC.
that's pretty believable considering the BootP button/right click difference that people have known about for years.
so if it was bricked, how were you getting a connection to communicate with controlflash?
Yes, unfortunately the DF1 driver through rs232 is not working either. It just doesn't get far enough into the boot to activate any communcations. tried all possible settings, multiple usb-rs232 adapters, etc etc. I believe i've tried every possible outcome to get it to work.
short of opening the case and trying to get to the pins on the ICs (which i wont do so we can get our warranty on it), there isn't much left to work with.

Yah, thats not good
I have maybe 500-700 or so that I have programmed and never had an issue BUT with 98% of them I use the flash drive, now that said... I have not had any customers tell me that they had an issue either
Is it the same PC that did the other one also?

Same PC. I can't imagine it would be an issue related to one specific pc though. a different coworker has had some issues before with download errors, but never so bad it wasn't recoverable. If it was myself that had the problem I'd have a bit more direct info as well as screenshot of the errors, but oh well.

Hello,
I got the same situtation, the Micro820 is bricked.
Same LED's stays On, and after a little while the Red fault button comes On.
Tried everything you tried, like SD card, RS232, but nothing worked.
Did you manage to find a solution?

The solution has been this so far.
1) Return the unit to whoever sold it to you and ensure you have cash in hand.
2) Never suggest or sell Micro 800 series again.
In short, no, nothing worth putting time into to find out why it fails to run after a simple download.

Please enlighten me…
Surely, this isn’t a secret trick to make bootp more reliable .?
It's funny, but not like a Ha-Ha funny....
Instead of fixing the problem, they just put a technote out to address it.

one of the many things to try that they list if it doesn't work.

Ahh, I must try that next time.
Surely the button & right click must call the same code underneath though.?
