Hecate 6.0.3

  • Added mitigation for bad chainloaders leaving sd gpios bad.
  • L4T: Now some 2019 Samsung T210B01 RAM chips can be overclocked to 2133 MHz for Linux/Android.
  • L4T: Added a mandatory change to support DDR200 UHS SD bus speed for Linux/Android.
  • Fixed an edge case where if hekate was run and the rtc alarm was triggered after that, booting from HOS would shut down the device. Since the Switch was woken up via power or USB in that case, all flags are now cleared during HOS auto power off checks.

Nyx 1.5.3

  • The SD Card/eMMC benchmark now hangs less between each read, in order to stress the cards more.
