--- layout: devinfo app: TWL_EVA_PRE_IMPORT altname: PRE_IMPORT category: [TWL EVA] sequence: TRUE redirect_from: /dsidev/twl_eva_pre_import.html group: true preview: /preview.png --- When a DSi has gone through the factory's BOARD testing, it is left with no firmware and only the SDMC Launcher bootloader. This bootloader is used to launch PRE_IMPORT off of the SD card. PRE_IMPORT will then install factory firmware and a bootloader that is functionally like the release version.
Factory firmware is like any other prototype firmware except for the fact that it contains an autoboot only Launcher. This means that it has no accessible menu and is only able to run inserted cartridges. Autobooting is all prototype firmware needs since it is just used to launch other versions of TWL EVA. This firmware is deleted once IMPORT installs the final firmware, but headers can often still be found in unused DSis. Below is a list of all the titles and versions that make up factory firmware for retail and dev consoles.
The retail PRE_IMPORT firmware is available to download through this website in the X6 DSi and factory firmwares release!
The process list for PRE_IMPORT is shown below. The HWInfos created at this stage are dummy files.
