Updating m33 firmware
Various other devices, such as digital cameras, wireless routers and smart TVs, may also run custom firmware.If you have OE/M33 firmware lower than 3.52 M33 please start from Section A. Emu NANDs could also be updated separately from the usual system NAND, allowing users to have the latest system version on the Emu NAND while retaining the vulnerable version on the system NAND; thus making online play and Nintendo e Shop access possible on outdated 3DS system versions.Emu NANDs were obsoleted by the release of arm9loaderhax, a boot-time ARM9 exploit that allowed people to safely use Sys NAND and update it, as CFWs started patching the OS' update code so that official updates wouldn't remove the exploit. (C.4) Go to Recovery mode (Power off your PSP by holding the power button for 10 seconds.
The modding scene of the Nintendo 3DS involves both flash cartridges which emulate an original game cart (which can be solely used to play untouched game cart ROM backups) and custom firmware (software which patches the official firmware "on the fly"), which requires an exploit to obtain control of the ARM9, the 3DS' security coprocessor.
Unlike the Play Station Portable, there is currently no native CFW for its successor, the Play Station Vita, although there is a CFW framework.
There exists e CFW for the PS Vita, too, meaning custom firmware for PSP running in the PSP emulator of the PS Vita.
However, this exploit required a downgrade to a very early system version to get the console's unique OTP, necessary for the installation.
On May 19, 2017 a new exploit called boot9strap was released, replacing arm9loaderhax and allowing users to get even earlier control of the system, granting code execution in the context of the boot ROM and thus a cleaner environment, with no downgrades or OTP required.If you have OE/M33 firmware equal or greater than 3.52 M33 and lower than 3.52 M33-4, please start from Section B.
