3DS System Version 10.4.0-29 is now available
That’s right, Nintendo published the System Software 10.4.0-29 for the Nintendo 3DS! With this release they only improve the system stability (as always) which for us means they patched exploits with this firmware.
3DS hacker Smealum mentions not to update because Nintendo changed a lot in 10.4.0-29. For example they added a check for a few games: if the game has a update you must update it otherwise you can’t launch it, like the Hax game Ironfall. But if you update the game you lose the Exploit in it.
apparently nintendo made it so you can't launch games that have an update unless you update them on 10.4. so if you update, bye bye ironhax

The good news: Smealum updated ninjhax which seems to work fine on 10.4.0-29. At the moment smealum can only test ninjhax but he still updated the other Hax payloads too. Unfortunately he isn’t sure if menuhax or n3ds browserhax still work.
