You can extract the flash memory via the debug port of the box and the esptool. Keep your backup! Please use a recent version of [esptool](https://github.com/espressif/esptool). (>v4.4)
Please connect the jumper J100 (Boot) and reset the box to put it into the required UARTmode. Connect your 3.3V UART to J103 (TxD, RxD, GND).

## Introduction
Grab your favourite USB-UART **3.3V** interface, recommending those with DTR or RTS port to automate board reset. You may also use a CC3200 Launchpad, but then you will need to reset it by hand. SOP2 need to be pulled high while reset to set the cc3200 into UART-Mode.

You may have a UART to USB adapter that supports both 3.3V and 5V. In this case you should find a jumper on the board to select the correct mode. You can see examples of such jumpers here (but there are others.)
**In any case, make absolutely sure that 3.3V (often labelled 3v3) is set or you will frie your board!**

### Checks
* Did you do the reset?
* Did you connect Toniebox rst to UART dtr and use the --reset dtr parameter?
* Which UART version are you using?
### Solutions
* Do not use a USB-C UART. They seems not to work reliable. Choose a mikro-USB version instead.
