Dear Alex, thank you for the mail.

Rebuild the firmware from the external SD card :
A. This is a manual re-build firmware procedure for your reference (recovery and cure rate is more than 90% )

B. Download file : [ to PC ]
- Uncompress/unzip it to ROOT directory of a MicroSD card
[PC->SD] ( one file , one folder )
- 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
