Nintendo Switch V2 Softmod ((install))
While minor userland exploits like "Caffeine" existed for very early V1 firmware (up to 4.1.0), no equivalent has been found for the V2's kernel or BootROM.
It became a game of whack-a-mole. Hackers had to find new browser exploits to keep Caffeine working. It was a fragile softmod, prone to breaking with every new system update, and it wasn't a "true" coldboot solution. It required an internet connection and a specific DNS setting to trigger the exploit. nintendo switch v2 softmod
