Are you sure all resistors and traces near UR930/40 are good?
You can try changing UR940.

I found nothing. Returning it to the customer.
After putting the board back i see a round circle with an exclamation mark. What do i do now?
Device isnt detecting in DFU Mode. I tried the key combination method and the jumper method too.
I am stuck. Require immediate assistance
Tried with Power Button / Audio Board / Battery / Display Removed as well

I have connected the switches but its till the same. I think the machine goes into dfu as the trackpad stops clicking , but it doesnt detect.
Connected to the port closest to the screen. tried different cables as well.
SOC_DFU_STATUS is 1.2V
Tried a different Host Mac as well.
