So the other day I wanted to flash the Open Thread firmware (the Open Therad-only firmware, the files that start with "ot-rcp") on my second Sonoff ZBDongle-E using the awesome web flasher on my Mac.
Low and behold ... it got stuck at 0.0% ... so the question arises: did I brick my dongle or not?
Proofs it did not. I just had to do two things:
1. Use the SiLabs USB driver for my Mac.
You can find the drivers here for Windows and MacOS (worked with Sequoia 15.3.1).
Download, unzip and install. Make sure you follow the steps to allow kernel extensions (the installer will tell you what to do).
Note: this comes with an uninstall script as well.
2. Boot the Sonoff ZBDongle-E in a kind of recovery mode.
We just have to disassemble the dongle, which is really easy;
Note: for some reason this did not work the first time, so I reinstalled the USB driver and then things worked. I also flashed the normal firmware (listed in the webflasher dialog) first and did the Open Thread firmware. Aat this time I used "ot-rcp-v2.4.5.0-zbdonglee-460800.gbl".
