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. -### Touch Board VER:1.1 + +### Touch Board Ver:1.1 ![](https://github.com/arendst/arendst.github.io/blob/master/media/SONOFF-T1-R2-UK-GPIO-PIN-OUTS.png?raw=true) 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.

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.
