Wasn't getting notifications on my droid turbo anymore so tried factory reset of iCam HD. Never beeped. Blue light never flashed. On power-up, blue light comes on and stays on forever. Camera doesn't move/try to calibrate, nothing.
Tried to upgrade firmware by downloading but dropbox gives 404 error, link not found. Please help. Thanks.

A. Please must use this tool to format the SD card on PC
Rebuild the firmware from the external SD card : This is a manual re-build firmware procedure for your reference
(recovery and cure rate is more than 90%)
Download file
- Uncompress/unzip it to ROOT directory of a MicroSD card [PC->SD]
- Insert the card to the camera
- Plug power cord of it. CAM will auto detect the codes in the Card (beep) to do the update ( blue light is on )
- Auto motor calibration/rotation (About 40~50 seconds)
- Wait till front blue led is blinking. (About 2-3 minutes)
- Unplug power cord
- Take card out
- Plug power cord again and the blue led will keep blink ( waiting for installation )

Installation: , If you are successful, please erase the card for normal use.

PS – this is what you see during the process
Insert the card with unzipped files
Plug in power
Short beep ( camera detect and read the files ) in 5 seconds
After about 40 seconds
Two short beeps ( writing complete )
Blue and Green lights blinking – done ( wrote in )
Unplug the power
Remove the SD and erase it
