I think I Bricked it?

[msp116]

Pretty sure I bricked my Dahua PTZ trying to upgrade firmware....can anybody point me in the direction of a dummy guide on how to fix this?

Now the camera can't access from webpage? Still can ping the IP? Can try to make a hard reset and test again.

If camera can be powered and can't access from webpage, camera bricked. Need ftp to do serieal port flash to bring the camera back

Yes the camera powers on, but no I CANNOT access the web interface. It tries to communicate with the switch then after about 5-10 sec it goes out and starts all over again. How or where would I communicate with it over a serial connection?

I recommend you to read through the above thread first.

If your camera still has a working bootloader (assume it does) then you can flash it easily, because:
The camera tries to download a file called "upgrade_info_7db780a713a4.txt" from a TFTP server running on 192.168.254.254 and executes the commands in said file in the bootloader (U-Boot) shell.

I really appreciate....can you confirm what is the latest working firmware for this?I didn't realize I tried to upload a US version firmware...

 

[msp116]

I purchased the UART cable. I have tried using the RS485 on the pigtail of the camera but I cannot get it to work. If anybody has any suggestions or knows some that can assist in repair I would appreciate....Tks

 

[tigerwillow1]

Somebody else will know more than me. I believe the pigtail RS485 is used for controlling the PTZ functions, and the serial port you need is somewhere inside the camera case.

 

[msp116]

Yea...I cracked open the back of the turret...there doesn't seem to be a serial port Connection that I can see...was hoping to find some sort of diagram online but bo luck...

 

[msp116]

Ok so Im stumped I have tried every connection I could find in the turret and in the housing. The only place I seem to get anything is the 4 pin connector under the top housing of the unit see pic....the other 3 pin connector on the turret next to the SD card and reset switch has a jumper on it...I tried checking it with a meter but get nothing...anybody out there have any other ideas I'm open to suggestions.....
