content: So, I have a uni-t UTi260MIt was working until I dropped it.opened it to find disconnected pcb to usb-c connector cable connector and noticed how sharp of a turn the cable made. reconnected itthen after a while, it stopped working again. Opened it to find that at a pinch point, the cable broke completely. It was made of flex PCB and was pre pitched from factorycan see the breakpoint in photo.Have you guys had any luck, trying to get replacements from Uni T?

content: Could it be, it's a standard phone connector, epoxied into their connector holderHelp if you recognise itOtherwise I'd have to resolve to soldering wires from electromagnet to connectors to make my own cable which is pain in the cunnilingus

content: Failed at flex pcb repair.Maybe I should work at the other end where I can see a chip labeled Realtek rts5803 (it's an USB2.0 PC CAMERA CONTROLLER WITH COLOR PROCESSING)

content: What the connector boils down to.Man, USB c is so confusingI wish I knew more about it.Usb 2.0 used to be so simple with 4 wires, here, there are multiple.I know, the chip used in it is USB 2.0. i wonder if i can just cut open the USB A end of USB C otg connector and solder them to have em workingApparently there are 6 wires going out of the usb connector into the camera's connector

content: Somehow got it to work on windows, and it shows up as normal camera but it doesn't work on the android app that it used to work with (uni-t thermal) and neither with otg view. Kind of unexpected.

content: First thermal selfie after repair.There is a wire that used to run from Camera PCB to usb and connect either to sbu or cc. (I do know, one of those is for letting the phone know of connector's orientation but I'm using an OTG cable here.) Maybe that's the culprit for it not working.I wonder if there's a windows app that can map temperatures for this thing. The fact that Windows can capture it without needing drivers says quite a lot for windows 10 before it became a spyware.
