After further inspecting my FTDI programmer through Ft_prog, my serial #A50285BI indicates that I have been using a fake chip/programmer this whole time!

It doesn't seem to be "bricked" but this could very well be a reason for the failed flash attempts.

In regards to my sonoff, Ive tried to hold the button through the entire process on a few flashes but this still failed to produce anything different. My question is that even if i do get a complete flash every once in a while, why is there zero serial output from the port? If the board was dead it ...

I may just be flashing with improper parameters but i cannot get any info about the chip in the picture so im not even sure if its 1mb. The ones i ordered are the 4mb chips that have been talked about in other sonoff threads. link >>> http://www.ebay.com/itm/201098254024 currently 10x for $2.49 free...

I ordered another ftdi232 basic and (10x) 4mb memory chips to swap in. Unfortunately it will be a couple weeks before I get to try these out. It would be silly to have to replace the memory chips for this to work but I've noticed the ones on my board are different from others so maybe this has somet...

just tested with an external measured 3.3v battery supply and still same result. Flash firmware end up crashing less than half way through. this is the output from espeasy: writing flash ....................................................................................................................

I too have recently gotten in a shipment of 5x sonoff basic switches from ITEAD this past week and am having a very similar issue. my pins have been soldered on so I know this is not the issue. It takes about 10+ attempts to get espeasy to do a complete flash without failing somewhere in between, us...
