Seems Nintendo have released a firmware that blocks hacking, heres the info :
This is a speculative post, so bear with me. After analyzing the Switch firmware 5.0.0 changes and reading SciresM's tweets, it looks like Nintendo is adding support for a new hardware revision of the Tegra CPU/GPU which is a SOC (System On Chip) dubbed 'Mariko'. The new firmware also includes a RomFS update with what seems like new crypto and support for the upcoming 'Mariko' chipset. My guess is that Nintendo is doing what Sony did with PS3 SuperSlim (déjà vu lv0.2), they are adding a new bootrom which plugs the current vulnerability and locking the lowest firmware to 5.0.0 for the new hardware in silicon. I agree with SciresM who wrote: 'Might be a good time to pick up a console with a vulnerable bootrom
