So I can't replicate this accurately with my MagTag, but I did experience something similar yesterday.
Here's how I fixed it:
1) Enter ROM bootloader mode, https://learn.adafruit.com/adafruit-mag ... -3076820-1
2) Download the bootloader for MagTag, https://learn.adafruit.com/adafruit-mag ... -3077972-6
3) Used the Web Serial ESPTool to erase the magtag, then upload the new tinyusb bootloader binary, https://learn.adafruit.com/adafruit-mag ... al-esptool
4) Restarted the MagTag and dragged a new WipperSnapper UF2 onto the BOOT volume.
I'm not yet sure where/how it's getting stuck in the bootloader.

Re: Bootloop on Magtag
Do you see the WIPPER drive mounted on your computer? Or any boot drive?

Re: Bootloop on Magtag
On a win10 box, it does pop up long enough to show a "wipper" disk with a secrets.json and wipper_boot_out.txt
I was able to double click the txt file before the loop only once, but the file was blank.

Re: Bootloop on Magtag
SandPig + Scottlnrd - I spent today working on this issue. Attached is a new version of WipperSnapper for the MagTag. Please let me know if it has the same issue, or creates new issues.

Re: Bootloop on Magtag
First, you work too late. I hope you love what you do. I just wrapped a 16hr day and there is zero love there! (totally my fault)
Second, it worked! MagTag is online and button presses (seemed like a good test) are working as expected. You rock!
The neopixels do flash green every few minutes, but it doesn't seem to be an issue so I'll assume that's a positive feedback thing.
I'll report any oddities that I come across.

Re: Bootloop on Magtag
This is to be expected, that's a status indicator letting you know the hardware is still connected to IO.The neopixels do flash green every few minutes, but it doesn't seem to be an issue so I'll assume that's a positive feedback thing.
NOTE: Beta.4 has been released and includes the fix for the magtag bootloop.
