Dear Ravi, thank you for the mail.
The manual firmware rewriting is the last method to recover "a solid blue light, no response to hardware reset at all" camera. Please try it again. If failed, then the camera may need a physical repair service.

A. Please must use this tool to format the SD card on PC
https://www.sdcard.org/downloads/formatter_4/index.html

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%)

- Uncompress/unzip it to ROOT directory of a MicroSD card [PC->SD] ( one
folder and one file )
- Insert the card to the camera
- Plug power cord of it. CAM will auto detect the codes in the Card (a beep)
to do the update ( blue light is on )
- Wait till front blue and green leds are 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: https://www.youtube.com/watch?v=V-j_OzXsANo , 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
