+# Manual Flash / MacOSx
+
+After trying to get the python script to work, it seemed easier to do this manually using curl and the dns-sd process in MacOS
+
+## Requirements
+- Sonoff DIY (firmware 3.1+)
+- OS with curl and mDNS discovery tool
+- `sonoffDiy` SSID on your router
+- Copy of firmware (e.g. [`sonoff-basic.bin`]) on a local webserver
+- SHA256 sum of above firmware
+
+### Verify and/or update eWelink firmware version
+- Open the device and remove the jumper labeled OTA if present
+- Power on device and connect to eWelink
+- Update eWelink firmware to at least 3.1 (mine came with 3.0)
+
+### Discover the unit ID:
+- Power off the Sonoff DIY device and install the DIY OTA jumper
+- Create a new SSID on your router:
+  - SSID: `sonoffDiy` (_**case sensitive!**_)
+  - Password: `20170618sn`
+- Wait for the Sonoff to connect
+- Using `dns-sd` search for the mDNS details:
+~~~~
+$ dns-sd -B _ewelink._tcp
+ Browsing for _ewelink._tcp
+ DATE: ---Mon 12 Aug 2019---
+ 20:19:31.956  ...STARTING...
+ Timestamp     A/R    Flags  if Domain               Service Type         Instance Name
+ 20:19:31.957  Add        2   5 local.               _ewelink._tcp.       eWeLink_1000988699
+~~~~
+
+We've found here our ID is **1000988699**
+
+### Upload firmware
+- Upload firmware to a webserver available on the SSID create above
+- Verify sha256 sum of the firmware file:
+
+~~~~
+$ shasum -a 256 sonoff-basic.bin
+ 1da0e89be4c01df033fa6da9d0c1db58c3deea354d7ad194f607d1f518db48f9
+~~~~
+
+### Flash and confirm
+- Test with /zeroconf/info POST:
+~~~~
+$ curl http://192.168.1.164:8081/zeroconf/info -XPOST --data '{"deviceid":"1000988699","data":{} }'
+ {"seq":2,"error":0,"data":"{\"switch\":\"off\",\"startup\":\"off\",\"pulse\":\"off\",\"pulseWidth\":500,\"ssid\":\"sonoffDiy\",\"otaUnlock\":false}"}
+~~~~
+- Unlock OTA updates
+~~~~
+$ curl http://192.168.1.164:8081/zeroconf/ota_unlock -XPOST --data '{"deviceid":"1000988699","data":{} }'
+ {"seq":2,"error":0}
+~~~~
+- Flash firmware
+~~~~
+$ curl http://192.168.1.164:8081/zeroconf/ota_flash -XPOST --data '{"deviceid":"1000988699","data":{"downloadUrl": "http://192.168.1.80/sonoff-basic.bin", "sha256sum": "1da0e89be4c01df033fa6da9d0c1db58c3deea354d7ad194f607d1f518db48f9"} }'
+ {"seq":2,"error":0}
+~~~~
+
+### Post Steps
+
+I carried on pinging 192.168.1.164 for about 30 seconds until the Sonoff rebooted. The normal "sonoff-XXXX" SSID was now available and ready for configuration.
+
+Carry on setup as usual
