This is mostly a libctru bug (well, sort of). This can only happen to built-in sysmodules, and to processes waiting for err:f, that fail to obtain handles through svcConnectToPort first try; and only prior to 11.0. Prior to fw 11.0, kernel didn't zero-initialize output handles, and thus the output handle gets filled with junk (leaked kernel stack data) in case of failure. Libctru does not account for this, and closes such handles anyway (in srvInit, errfInit, and possibly more). The problem is that, in our case, that garbage was equal to 0x8000, actually a valid handle, in fact the first handle to be created (and not closed) in a process... a handle to KAddressArbiter. Accidentally closing this handle resulted in one or more KIPs spin-waiting and starving core1, resulting in an inability to boot. We fix this simply by replicating what recent k11 does, in kext (for svcConnectToPort). For srvGetServiceHandle, add two layers of safety.
Luma3DS
Noob-proof (N)3DS "Custom Firmware"
What it is
Luma3DS is a program to patch the system software of (New) Nintendo (2)3DS handheld consoles "on the fly", adding features such as per-game language settings, debugging capabilities for developers, and removing restrictions enforced by Nintendo such as the region lock.
It also allows you to run unauthorized ("homebrew") content by removing signature checks. To use it, you will need a console capable of running homebrew software on the Arm9 processor.
Since v8.0, Luma3DS has its own in-game menu, triggerable by L+Down+Select (see the release notes).
