  • How to use Partition Manager for Linux/Android?
    For L4T Linux you can use the official Ubuntu Bionic 3.2.0 or newer release or any other distro betas.
    For android you need to build Android P or Q which support/require the new partition scheme.

  • My Joy-Con drift when in Nyx, how to fix?
    Nyx applies an auto calibration at boot. That happens when you hear the rumble. If you press the sticks before, then a wrong calibration will get applied.
    To fix that on the fly, simply remove the Joy-Con and re insert it. This always causes a new calibration. Just make sure you don't touch the stick when you reinsert.

  • I don't care about emuMMC/Linux/Android. Can the Part manager be used for something else?
    Yes. You can still reformat your SD card to a single FAT32 partition.
    You can even use it when you have exFAT and you want to format to FAT32.
    It is also suggested to format your sd card via hekate. That's because it prepares it for performance. something that many partitioning tools neglect.


Check readme.md for more.

For maximum performance of UMS in Windows, you need to run nyx_usb_max_rate__run_only_once_per_windows_pc.reg, only once per PC you have.
It only affects hekate's usb device. You can also view that file with text editor and see what it does. Linux/Mac OS users do not need that.

How to update:

  • Drag n drop bootloader folder into sd card root and hit merge/replace.
    No need to delete that folder first, especially if you want your configs and payloads.
  • Inject the new hekate_ctcaer_x.x.x.bin payload at least once.
    You can avoid re-injecting hekate if you replace bootloader/update.bin with latest hekate_ctcaer_x.x.x.bin.
    • If you updated while in Nyx then just hit Reload Nyx and it will check if update.bin is newer and load it.
    • Or you can copy hekate in /bootloader/payloads and launch it from Nyx Payloads menu.
    • Or if in HOS, you can r2p into newer hekate.
