Hello everyone,
I bought a switch that doesnt power on on Ebay. After replacing the charging port and the PI3USB IC the Switch was booting and working fine.
The previous owner of the Switch has set a parental code on the console and doesnt remember it so i tried to boot on a CFW to get the Device ID and remove the parental code but the console was not detected by TegraRCM even if it was really in RCM Mode. When i plug the Switch into my computer in OFW its not detected at all. Outside of that the console is charging fine and working on a TV in the dock.
Ive check the D+ and D- rails ont the motherboard and got nothing on the ocsilloscope on the D+ and a steady 400mv on the D- while on a working Switch I got some pulses on each lines. Ive check the continuity between the pins of the connector and the test points (A1 to A2 and B1 to B2 on my picture) and its good. Ive check with a multimeter in diode mode on the D+ and D-, on the working Switch i have .500 on both but on the non functionnal one ive got OL on both. Ive check the component ive noted F on the picture which I presume is a filter and its good.
Does someone have a solution for that or the issue is coming from the CPU and there is no hope ?
Thanks
