Trying to determine if this ESP32-S3 is completely dead or only "partly" dead. 'Cause if it's only partly dead that means it's partly alive. Where's the bellows?

Ordered another ESP32-S3 made by same manufacturer as the original so I can avoid the various (notably less expensive) versions often with problematic quality. The short was my fault. Also ordered some new connectors that should avoid the situation that likely caused the damaging short. So, another try tomorrow.
Managed to partially (?) fry one ESP32-C3 as I forgot one wire connected when changed power from USB to separate +5V source. Changed the damaged output for another pin and everything seems to work just fine. Has been running 350 km away now for several weeks, so I won't worry about it until snow melts, it is about one meter underground logging and transmitting temperatures.

If you coat the JTAG probe in chocolate it goes down easier.
Brownout warning loops. 3.3v supply mostly at ~3.2 dropping every 10 seconds or so very briefly to 2.9v. Regulator likely fried. I think the 3.3v supply was momentarily shorted. Board declared completely dead.
