Well, short of sending both to someone who has done it before and has a
known go physical setup. You may have only one option, buy another one
or two...
I would be willing to try the updates for you if you pay for shipping
both ways. This assumes shipping is reasonable and you are in the U.S.
Maybe time will pass and you'll have an "Ah ha" moment. Maybe buys some
fresh 9V and try the flashing. A fresh 9V should be enough to at least
flash.

I see your point Chad. Actually now I am trying to upgrade/downgrade
the firmware in A position + external supply (USB 5V 1A to IOIO JST
connector, homemade adaption made by myself, works fine) but still no
luck... I don't know what to do anymore... I think I have tried almost
everything!

My experience with PIC chips has taught me that "not enough power"
during the burn/flash/programming time will give significantly
inconsistent results. Your problem is sounding more like that since
you've basically done it on two IOIOs and not a procedural problem
like
I faced. At the time of updating the firmware there was insufficient
power applied or the IOIO was in H instead of A - these are my
theories.
I would encourage you to re-update and/or roll back to a prior
versionsV0330. fwiw I used a 9V battery and it did not last long
powering the IOIO OTG or for that matter any PIC chips from my
projects
I used prior during the flasing process. I dropped it quickly and
found
a usb power supply terminated pins on it and connected the IOIO.
My plug
runs 5V DC @ 2A. Try updating again verifying all power needs. I am
going way out on a limb for this IOIO OTG PIC model but I know my
other
PICs require 12+ Volt minimum to achieve a good flashing, the PC's
USB
will provide some power, but is likely needing to be supplemented
with
external. Again stating this from experience and not looking at the
IOIO's PIC's specifications/requirements.

them sometimes works with my smartphone other times doesn't. The
other one doesn't work at all. This makes no sense I know...

that's what I was trying to say on the first post, it is highly
probable that I've done that and also with H position on switch...
I can't remember but I think I've done it.

those tries and procedures I managed to make them recognized as
COM ports in both H or A positions.
