If (u8*)0x10000000 bit 1 is clear (which means that this happens only on hard reboots), it does the following things:
 
−
* Hashes data from the region 0x10012000-0x10012090 using SHA2.
 
−
* Initializes AES keyslot 0x11 keyX, keyY to the lower and higher portion of that hash, respectively.
 
−
* Decrypts arm9_bin_buf+0 using keyslot 0x11, and initialises keyX for keyslot 0x15 with it.
 
−
* Initialises KeyX for keyslots 0x18-0x20 with the output of encrypting a certain binary sequence using keyslot 0x11. These are presumably New3DS-specific keys.

It sets KeyY for keyslot 0x15 to arm9_bin_buf+16, the IV to arm9_bin_buf+32. It then proceeds to decrypt the binary. When done, it decrypts arm9_bit_buf+64 using a fixed key and makes sure it's all zeroes. It it is, it jumps to the decrypted addr. Otherwise it will just loop forever.

The following system-modules were updated: AM, camera, cfg, codec, gsp, hid, ac, cecd, CSND, dlp, http, ndm, NIM, NWM, SOC, SSL, PS, friends, IR, BOSS, news(notifications), RO, NS, and act.

The following applications were updated: System Settings, Download Play, Nintendo 3DS Camera, eShop, System Transfer, and NNID settings.

The following "applets" were updated: ErrDisp, Home Menu, camera, Instruction Manual, Game Notes, Friend List, Notifications, error, Software Keyboard, appletEd, PNOTE_AP, SNOTE_AP, extrapad, mint, Miiverse, and Miiverse memolib.

An applet with TID-low 00008B02 was added, "solv3". The description from the ExeFS icon is "Post to Miiverse".

The following titles were also updated: 0004009B00012302, EULA CFA, NGWord bad word list CFA, Nintendo Zone hotspot list CFA, NVer, CVer, 0004001B00018002, 0004001B00018102, and 0004001B00018202.

NS_CFA was updated, the following new file was added to the RomFS: "qtm_black_list".

NATIVE_FIRM was also updated.

New3DS

New3DS versions of most sysmodules were added with this upgrade.

This upgrade included 3 new sysmodules:

  • NFC -- talking to NFC hardware (over I2C).
  • MVD
  • QTM -- camera headtracking? (over I2C).
