content: Hello guys.First time to post my awful experience.The firmware is the latest (Firmware_B2L_V5.5.15_220509)As you can see the link below, when it powers on, after only 5 sec it just go freeze and dies.Pressing power button to restart doesn't solve the problem and it completely go brick.https://youtube.com/shorts/JoK44L6VJm8?feature=shareIs there any means to hard reset?Since it doesn't show the menu bars nor I can reach on the menu or connect to Hikmicro viewer app, I don't have any means to update or revert firmware in normal wayI did a quick search but I couldn't find anyone has similar experience..Maybe I have to tear down and connect UART to do hard reset? I see following astonishing work by Fraser and if it is only thing to do I am up for it.https://www.eevblog.com/forum/thermal-imaging/hikvision-ds-2tp31-series-thermal-camera-teardown-307840/msg3942805/#msg3942805

content: Easiest Fix is RMA the camera and get a new one. That seems to be a known bug.QuoteWhy would you want to void the warranty? It's a new camera - send it back to the seller and request a fix or new one.

content: Thank you for your reply.I thought it would be the firmware problem and any of other device would break down also.The bug is after I update to the latest firmware(V5.5.15_220509 from V5.5.14 210929), before update there wasn't any problem.After update, when I use only with lower thermal range, it works fine. The symptom occurred when I switch to higher temp range (100c-500c?) it just frozen then it became just like this ever since..Regarding RMA unfortunately it was from eBAY and there wasn't any purchase receipt / warranty paper...

content: Hi markb1980Thank you for the link. I am surprised they could update the firmware that quickly.Unfortunately, It is too late for me because the thingy is, whenever I start the device, it goes freeze in 5sec after start up without showing any menu (nor I can access the menu like the video I post).Therefore having new digicam.dav in the root folder does not trigger the automatically update (it goes brick before that..)Could you ask your contact in Hikmicro about my situation? I wish there would be any hard kill switch with safe mode start, or hardwire the firmware from the beginning etc..Thank you again for your trouble! I just hope I could unbrick this device anytime soon...

content: Usually that works because they flash the firmware before booting as far as I know...Try contacting the support yourself. You can also join my FB-goup. There are 2-3 folks from Hikmicro.
