Looking to restore Arduino to HUZZAH32 Feather

I have an Adafruit HUZZAH32 Feather which I have flashed clean with JTAG. I wanted to restore for Arduino use, how is this done?
I was thinking you can use the 'ESP32 DownloadTool' in the Espressif Flash Download Tool v3.4.8, is this possible?

it is as simple as building and flashing with the arduino ide. No need for the download tool

My goodness, it was just that the speeds were too high.
Original: 921600/80MHz
Working: 115200/40MHz
Thanks for the input and the nudge, now I am back up and running!

Speeds are interesting. I am running with 95% first time flash using 921600. I am using 12 inch USB cables between my ESP32s and a powered USB hub. Just an FYI.

it really depends on the board.
On my DOIT I can do 921600 when it's cold, when it is warm it fails 2 out of 3 times.
My Pycom lopy can handle 2m baud, 80mhz QIO flash. Hooked up on a 3m very old usb cable. And has never failed me.
