Solid Red LED NeoPixel
The ESP32-S2 was working fine from a battery bank until this dawn, transmitting data from the I2C devices to AdaFruit IO. Then the battery bank run out of fuel, and everything was dark by the morning. I disconnected the battery bank and plugged the board into the USB charger in the outlet to restart the data flow and recharge the battery. However, I see only a solid red neopixel led and no connection attempts. So I get into boot mode, reinstall wippersnapper, the json... but the disk never changes into "wipper" it just remains "FTHR2BOOT"... and the neopixel LED remains solid RED when I am not in bootloader mode (then it is green). I guess I am missing something? Thank you very much!

Re: Solid Red LED NeoPixel
Could you try following the steps on this page to factory reset your device: https://learn.adafruit.com/adafruit-esp ... tory-reset
Then, try re-installing WipperSnapper

Re: Solid Red LED NeoPixel
Thank you very much for the suggestion, as the bootloader was functional and I was able to access the FTHR2BOOT disk I tried the "Factory Reset Firmware UF2" method and then tried the reinstall. Unfortunately, it did not work. Sincere apologies for not remarking on this in the original post.
What puzzles me is the meaning of the solid red neopixel LED... Any pointer to its decoding? Thank you very much!

What is on the FTHR2BOOT volume?
