- Power on and verify the device pops up on the Mobile hotspot Settings page
- Start ``\tool\tool_01DIY85(v1.0.0).exe``
- It should find the device
- Select it and play with ON and OFF to verify correct connection to device
- Power on and verify that the device pops up on the Mobile hotspot Settings page
- Start the `\tool\tool_01DIY85(v1.0.0).exe` utility
- The utility should discover the Sonoff DIY device
- Select the device and toggle it ON and OFF to verify you are connected to the right device
- Select Firmware flash
- Select pre-compiled or own compiled binary smaller than 500k. Do NOT SELECT sonoff-minimal as it does not allow to change any setting.
- Select the device in the flash pop-up and select OK
- Select a [pre-compiled Tasmota binary](http://thehackbox.org/tasmota) or your own self-compiled binary. It must be _smaller than 500k_. _**Do NOT use the sonoff-minimal pre-compiled binary**_ as it does not allow to change any setting.
- Select the device in the flash pop-up and then select OK
- Tasmota will be uploaded and started
Now continue as if you just installed Tasmota on the device.
Once the firmware upload completes and the device restarts, continue the setup process as if you just installed Tasmota on the device.
### Clean up
- Quit DIY mode tool
- Stop mobile hotspot
- Power off device and remove OTA jumper as it is no longer needed and might interfere with future Tasmota features using GPIO16
