    820-00165 liquid damage around SMC 0.02A died after UC

    Just tried this morning and it turned on, I will test furthermore. I have UC'd only the SMC area, just to make sure corrosion is not underneath. Thanks again,

    820-00165 liquid damage around SMC 0.02A died after UC

    Seems all the drama happened around the SMC Corroded track on R5193/R5117/R5177/R5100 replaced and rewired broken joints U3710 had a bad track to SMC_OOB line, rewired that After all this was repaired, it turned on and seemed ok, so I ran it over Ultrasonic Cleaner, then 0.02A and dead...

    I can see it gets to it. When I connect the usbc meter to the top port and Apple conf to the bottom one, closer to the trackpad. The usbc meter reboots after 10sec with the keyboard shortcut to DFU.

    yes tested with only bare board with SOC_DFU_FORCE pull up to 1.8V. Also in the case with disconnected audio and battery only. There is no oxidation residue apart than U8200. But again it seems to be washed with something like aerosol can as feels oily.

    Thanks. I have replaced U3100 with another one still stuck at 5V 0.23A on both ports. Still missing 1V1_LDO_BMC . Only different now under IR is that both ports seems to heat up T2 evenly, unlike before. Looking at the bootup sequence - https://logi.wiki/index.php/CD3215_Bootup_Sequence I went...

    Also want confirm if this is the expected behaviour? Could this be a cause of the system not getting detected under Apple Configurator. Maybe faulty U3100 or its circuit This is with SOC_FORCE_DFU jumper. When connected to the top USBc U3200 When connecte dto the bottom USBc U3100

    Sorry I must have not been clear. The one with oxidation was U8200. I have taken it out and cleaned underneath as it had bad solder joint on pin1 R3091 on U3200 looked like it had a corrosion marks. I was thinking it might have leaked under U3200 and was thinking to reball. But it is slight...

    Traces on the TBT ROM seems fine. LDO's are present apart than PP1V1_UPC_XA/B_LDO_BMC - 0V - Not sure if this needs to be on at this stage.

    Seems like it has been cleaned by another company. Slight oxidation residue around U8200 and R3091. Measurements around CD32s seems fine. No short anywhere. T2 seems getting slightly warm. Tried DFU both with keyboard comb and FORCE_DFU pads to 1.8 PP1V8_SLP2SR_PMUVDDGPIO which is nearby. i...

    Reballed UR500. It didn't had much underneath. Only corrosion in the area is on CR504, PP3V8_CODEC_VP side was almost gone I am assuming pins 21, 14, 7, 6 were soaked at some point. It is still same. When I press volume up, it shows volume UP OSD then, on second press shows forbidden volume...

    Replaced UR630 as balls underneath were completely corroded. Now Audio gets recognised for a second and disappears in the Audio Output secttings. Bluetooth audio works. Its strange, when i press the volume up/down it moves the volume bar now (before would just shows a forbidden audio sign) but...

    Can you try to boot external and try to install? Also perhaps to eliminate wifi, try usbc lan adapter if you have one laying around?

    I can confirm, that this model doesn't turn on without a battery. 20V 0.01A when the battery is not connected. I've replaced the battery and all is good. Thank you for your help @2informaticos

    Are you aware if this model needs a battery to turn on? I managed to FORCE_DFU and revived the system. While it is connected to power I managed to load the system, it shows the battery needs service but charging. Pulling 2A charging current. But the minute I disconnect the charger it shuts down...
