TTGO T-beam supreme sketch not working

[YetAnotherModelShip]

I have a TTGO T-beam supreme but I cannot get a sketch working. After uploading it always displays:
ESP-ROM:esp32s3-20210327
Build:Mar 27 2021
rst:0x15 (USB_UART_CHIP_RESET),boot:0x8 (SPI_FAST_FLASH_BOOT)

load:0x403cc700,len:0x2a68
entry 0x403c98d4

... but not the output of the serial.print() command in my sketch. How can I switch modes or whatever is needed?

Did you ever manage to figure this out, getting the same error?

As far as I can tell the T-Beam is stuck in receive mode. Take a look at this thread for the same problem in the T-Beam, but no sketch is working.

Relevant part:

I looked this up and found it was a corrupt boot area leaving it in a receive state. One recommendations was to use a command line tool to re-flash the device.

I used the command line tool esptool.py

I entered the following at the command line:

esptool.py --baud 921600 erase_flash ← erased the flash file
esptool.py --baud 921600 write_flash 0x1000 system-info.bin ← wrote out the system bin file
esptool.py --baud 921600 write_flash 0x10000 firmware-tbeam-US-0.9.1.bin ← wrote out the file for my meshtastic device
