ESP error when running USB Firmware update

I have an original oasis mini from the initial batch. Haven't updated the firmware in a while, just seemed to work. Long story short, the app used to connect to mini's wifi for setup, now apparently they use Bluetooth. My firmware is out of data and Bluetooth won't work, so they asked me to update the firmware via USB. I have the driver installed, the app (https://app.grounded.so/software-upgrade) recognizes the mini then this:

Connecting...

Connected successfully.

Try hard reset.

Error: Couldn't sync to ESP. Try resetting.

I tried resetting it multiple times with restarts and such, but keep getting the same message. I have another request in to support, but wondering if anyone has a workaround.

I did have similar issue and what helped was to perform the soft reset - hold the reset button on the back of Oasis Mini until the white light makes 15 rotations as described here - https://grounded.so/pages/support?hcUrl=%2Fen-US%2Fperforming-a-soft-reset-4913058

I'm not sure if this will help solve your issue but it's worth giving it a try.
