I bought a Yi Home 1080P (48USYJH1YF) yesterday, configured it, all worked well. Then I tried to install the firmware from https://github.com/shadow-1/yi-hack-v3 1 (by following the instructions). For my camera this had to be rootfs_y20 and homey20. I got a orange blinking light, then a solid orange one. This is not good.
Then I tried a couple of scenarios:

• Put the official firmware back on the SD card
• Tried the recovery file from https://app.box.com/s/cibs7n1mgvhqaqjlidtveegu1uajt5yr/folder/23494084746

Finally, I found your repository and tried to use it. The orange light blinks for a while at first, so there's definitely something going on, then it becomes solid orange after a while (a minute or so).

SD card was MSDOSFAT32 formatted, there are no file extensions in the filenames, I reset the camera a couple of times,… So I’m out of ideas of what I can do now.
So, the camera is bricked for the moment. Any idea how I can unbrick it?
