    Hello,

    I will to try to explain the problem:

    I get a 2nd hand Nintendo Switch with water damage. After my inspection I can see few water damage in (and around) usual chips (corrosion in M92T36, BQ24193, PI3USB) and battery connector (and bottom PCB in same area) then I clean the PCB and check some weldings, all looks like ok.

    I don't know the installed firmware. Only shows Nintendo logo then turns off.
    I can test that can charge with an usb tester but don't shows the charge icon in the screen.

    I checked the capacitors (and others) around M92T36, BQ24193 and PI3USB for any issue and all looks like ok.

    I can join in RCM mode but when I try to launch Custom or Oficial firmware I have the same problem, only "Nintendo" logo and off.
    I try to restore BOOT0, BOOT1 and RAWNAND extracting my own keys downloading and using an original firmware with TegraRcmGUI v2.6, memloaderv3, HacDiskMount1055 and ChoiDujour122b following this tutorial:



    Following the tutorial all looks like ok but when I mount rawNAND in TegraRcmGUI with memloader and I went to HacDiskMount step (minute 00:44) I can see something different, in the video the boy just mount sysNAND and ok but in my switch appears a message that tell me "Please select partition table. Primary and backup GPT are both valid but not the same, which one to use?" I don't know which is the correct so I try it with "Primary", then I finish the tutorial and no repaired, then I repeat with "Backup" and same problem.
    I try different firmwares (v9 and v6) and same problem.

    Now I can't see "Nintendo" logo and it's more difficult to join in RCM mode. What happened? How can repair my Switch?

    I have a NAND backup with the initial problem before do all this things.

    The chips looks like ok but I thing that I need to try to change it, because it's strange no see the charge icon.

    Some ideas?

    I appreciate some help.

    Regards.

    You should try restoring the backup, go into recovery mode, and formatting it. But who knows with water damage

    First thanks for your answer.

    I can't join in recovery mode.

    Keep in mind that this backup are just the initial problem data (just "nintendo" logo and power off) then don't solve the problem.

    Regards.

    I restored my (deffective) NAND to begin again to try to repair it.

    Now I can see again the "Nintendo" logo and then the console turns off
    and continues no showing the left charge icon during charging (but charge).

    I don't know if try with other firmware or... what?

    As I say the console gets hardware damage (water) but looks like a software issue but who knows.

    Try to change the BQ24193 and see if the problem with the charge persist.
    With the multimeter check pin 5 and pin 6 on M92t36. Plug the charger. If you have between 3 - 6v on pin 5 and 6, then M92t36 it's ok.
    You can still try a reflow on M92T36, BQ24193.
    You should try with another battery.

    It's reflowed with flux around some corrosive areas (maybe I must to reflow again) and I tried other battery that I can see in Hekate that is charged to 100%. And we are here, with the issue.

    I'm waiting to receive in... around 5 days a few of chips to try to change BQ24193 (or M92T36, or PI3USB).

    I test your suggested pins (I remember saw this suggestions in other threads and keep in mind to check).

    Here the results always with charger plugged:

    M92T36:

    Switch console OFF:

    PIN 5: 4,49v.
    PIN 6: 0v.


    Switch console ON (in Hekate menu):

    PIN 5: 3,29v.
    PIN 6: 3,31v.

    What do you think? looks like ok. I suppose that 0v. in pin 6 when console is power off it's ok but I don't know.

    Thanks for your answer.

    Regards.

    PIN 6: 0v.
