Modded an OLED with a picofly. Glitched perfectly, booted OFW fine, went into Hekate and started backing up the eMMC. About 15-20 min in I got a glitchy pattern on screen. Powered off, tried to boot back to OFW, got a loud buzz, then on the next boot I started getting Error 2162-0002 (X1: XTJ10830545244 / X2: 22.0.0).

Tore it back down and checked everything:

  • No shorts on any of the main rails but 3.3 rail is reading a little lower 0.2v in diode mode, was reading 0.38v before.
  • CPU/SoC rails all reading fine, nothing shorting on the caps
  • Picofly injection/power points all reading correct
  • eMMC is on the opposite side of the board and was never touched during the install
It glitched cleanly and ran OFW + Hekate for ~20 min, so I don't think the CPU is dead (it was clearly working during the session). Thermals were looking good too. The failure happened mid-eMMC-backup, which makes me lean toward an eMMC issue, but I want a sanity check before I conclude anything.

I've modded a dozens+ switches and never hit this. A few questions:

  1. Anyone seen 2162-0002 specifically after a Hekate eMMC backup, with clean rails?
  2. If Hekate can still read the eMMC when I retest, does that rule the eMMC out and point me elsewhere?
  3. Any known failure mode here that isn't eMMC and isn't a shorted rail?
If it makes a difference, this was sent in by someone, but they never used it. It was directly sent to my address and I can confirm it boots, but I don't know much else past that, if there was anything up with the emmc before.

I too sometimes get these 'untouched' and 'brand-new' items on my desk.
Never take a customers word for it.

Buzzing sounds are usually caused by coils, which in turn points to the power management MT92.
The coils are probably fine but the MT92 or some capacitors might not be,
Did you also check what the voltage rails look like on a scope?
