Dear Mo, thank you for contacting. If the camera does not response to the hardware reset procedure, this is the last step to try : ( if this fails, the problem is still; then, the camera is hardware defective, no software can cure )

We try rebuilding the firmware manually ( in case the ROM is damaged somehow )

A. Please must use this tool to format the SD card on PC (SD heath)
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 [PC]
- 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
to do the update ( blue light is on )
D.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

If the blue light is still on, it may still has the good chance. Please ensure the zip files are unzipped to the root directory of SD (One file and one folder with 2 files). No any mother folder above. However, if if the camera still can not detect the booting files in the SD card; then, yes, it is possibly defective internally. Thank you.
