Try option 1 **OR** option 2. This will cause the unit to reboot into flash mode. This is confirmed on a serial console (74880 baud) by the boot mode displaying (1,x) indicating that we are booted to the bootloader and not the flash. You can also confirm booted to flash without a serial console, the main led should be off and the backlight LEDs lit dimly.
There is no longer a need to solder anything to GPIO0 or to ground it while powering up for Ver1.0; this step is replaced by the above button sequence. However, GPIO0 to GND is the only way for Ver1.1 boards.

Notes:
1. There is not enough room with this reversion to fit a header pins on the programming port and still close the case.
2. GPIO0 is connected to the Helper chip on this version. Therefore, the only way to get Ver1.1 of the board into flash mode is to solder a lead onto the resistor R19 from pin 15 on the ESP chip (i.e., GPIO0) and connect this lead to GND on power up; the device will set all the touch pads to dim and the WiFi LED D3 will NOT be on at all.
3. Log on the J3 header is GPIO2
1. There is not enough room with this version to solder header pins to the programming port and still close the case. One possibility is to slightly bend the pins of a 4-way header and push it into the holes, removing it after programming.
2. GPIO0 is connected to the helper chip on this version, so the only way to get Ver1.1 of the board into flash mode is to solder a lead onto the resistor R19 from pin 15 on the ESP chip (GPIO0) and connect this lead to GND on power up; the device will set all the touch pads to dim and the WiFi LED D3 will NOT be on at all.
3. The connection marked 'LOG' on the J3 header is GPIO2.
**WARNING!!** Do not attempt to power the device from your serial-to-USB adapter when connected to the relay board. This draws too much power and will cause the ESP to reboot frequently and will reset all the configured settings.

## Sonoff T1 EU
For most devices, the [UK version flashing guide](https://blakadder.github.io/templates/sonoff_T1_1_uk.html) may work. However, for **2 Channel board version 1.0**, you need to solder (or otherwise permanently connect) GPIO0 (R19) to GND before powering the board and only disconnect them once the flashing is complete.
