#1 YOOZ mypad one tablet with damaged D+ D- Id tracks

Hi!

Got for repair dead "YOOZ mypad one" tablet
platform : C88/131206/V20

Found micro-usb power connector shorted inside and D+, D- and Id tracks burned.

Changed connector, now power is ok but could not find where to shunt Id, D+ and D- pins to motherboard, as tracks were damaged.

Need schematic or a clear topside mobo photo or any suggestion as where to link Id, D+ and D- pins to mobo.

Thank you

Hi!

Yes, it is, with very very slight changes such as MCU_RK2926 instead of RK3026.
So, thanks for the photo.

Could you P.S upload the topside of the mobo, that will help me bypass Id, D- and D+ missing tracks and fix the tablet.

Do you have schematic of this tablet ?

In the picture you can see a path after running into vias in place USB port. Just visually compare the place of destination guides on the path of the USB port.
