After playing around with some button combinations I think we finally got the ESP32 web installer working consistently for the T-Beam Pizza Supreme.
Here is the process we used:
- Open flasher.meshtastic.org in chrome
select Tbeam S3 Core, firmware, wipe and reinstall - Plug the Tbeam Supreme into the computer and wait for it to power on
- Power off the Tbeam Supreme
- Press and hold the PWR & BOOT button simultaneously
- Within the Web installer click connect, select the COM port
- Click INSTALL TBEAM-S3-CORE
- I release both buttons when it says Erasing.
- When it is done power off and power on your Tbeam Supreme and it should display the firmware that was flashed on the splash screen.
Let me know if this works for you guys.
