    Dump nand content on working ac86u

    What thickness should I get the cooper shim in? I am afraid that it would crack the die with a shim too thick. Currently having a fan blowing over the heatsink but I still think my sensor is somewhat faulty since the temperature doesn't increase significantly (beyond 2-3 celsius) without a fan...

    Dump nand content on working ac86u

    Fixed the issue partially, ran the jumper wires for Power Good Indication and Analog Voltage In. Now the temperature is hovering around 80 degrees Celsius instead of 120. Voltage measured at the inductor also fell to 1.46V instead of 1.65V which may be the reason that the CPU had such a high...

    Dump nand content on working ac86u

    I have a fan blowing on the rear heatsink 24/7 and the heatsink is barely warm to the touch. I think the sensor is fried since the graph shows a straight line rather than fluctuation under normal operation. The output goes to 1.62V I believe. Not sure if that's normal.

    Dump nand content on working ac86u

    Update, I received the replacement IC today and replaced it today. With the ripped pad for analog voltage in, the voltage supplied to the circuit is not 5.2V. Neither does Power On Good signal connected to the board. However, the router does boot up. I will add a jumper wire down the road if the...

    Dump nand content on working ac86u

    Would be doing this, I think I see where the trace PG leads to, but not AVIN. Will have to probe around and see where that gets me. Thanks for your help

    Or a wired router but there are better options out there I would say

    Dump nand content on working ac86u

    I have worked on it for a little bit last night. While wicking the pads, I realized I was using a non leaded solder with a tiny tip. I have ripped some pads but crucially its AVIN and PG which are pin 10 and 4 respectively. Any idea if it will work without them? I also tried a tiny DC-DC...

    Dump nand content on working ac86u

    That would be great! Saves me the trouble to source a NAND flasher and CGE. Still new with trying to fix routers and I did not find any schematics so far. Keep me posted and thanks in advance

    Dump nand content on working ac86u

    Hi, could you please update me if you manage to get a good dump of AC86U? I just took apart mine and I see both a UART connector and a JTAG connector. My router most likely has a bad CFE since the only LED that's on is the 4th ethernet port. Thanks!
