    Help me verify my NAND dump (attached) from LG SK10Y soundbar stuck in PLEASE WAIT - is it missing critical data?

    Hi everyone,

    I’m trying to bring a LG SK10Y soundbar back to life. Currently it is stuck in the “PLEASE WAIT” loop.

    My conclusion so far is that something fails to boot fully, but it does start via eARC and can play perfectly good sound until watchdog shuts it down.

    After dumping NAND with a T48 programmer, extracting with binwalk and exploring with Ghidra I think:
    • Kernel B is present, but no Kernel A. Is that normal?
    • SquashFS A/B are present
    • Bootloader is present
    • UBI region is completely empty (only volume 0 / layout volume exists)
    • No system.cfg, no dsp config, no wifi config, no calibration, no logs

    Can someone have a look at my dump, or provide a working dump (or the UBI volumes) from a SK10Y/SK9Y unit?



    Any help is much appreciated!

      Firmware file for LG SK10Y Soundbar stuck in Please wait loop needed
      by Daniel Larsson
      Hi,

      My LG Soundbar, SK10Y, has somehow ended up in an endless "PLEASE WAIT" loop and I am now starting to suspect that the firmware is causing this, and I can't manage to connect via the app to push a new firmware in as it never really starts.


      I can trick it to start via HDMI ARC and it actually starts up, flashes OPTICAL and then goes to ARC where the sound (including sub) is perfect, but the white led indicator keeps blinking and after 20 seconds it says "GOOD BYE" and shuts down.
      During these seconds the function button is not working...

      LG SN9YG Soundbar - Stuck with Please Wait
      by pauldow
      Another dump find, so someone must have given up on it already.
      The list price was $700, so I figure it's worth giving it a try.

      When I plug it in, the display briefly says Hello, then the volume level, the scrolls Please Wait. There are 4 LEDs under the display words that go in a three second loop of 2 inner on, all 4 on, all 4 off.

      From the remote, the volume level changes on the display, but that seems to be the only activity.

      The owners manual says to hold the microphone mute button for 5 seconds to reset, but nothing there.
