For some reason it started working when I changed the uploader to DIO flash instead of QIO flash. Also have there been issues with some of them having GPIO 4 and 5 switched? Mine are flip flopped from all the pinouts on the web

The ones I have are the same way with GPIO 4 and 5 flipped, it was a real pain in the ass in the beginning.

It is a spreadsheet. I then went to the tab called "Strapping" which is the bootstrapping information.

There you will find the following data:
