SystemUpdater

The SystemUpdater is a collection of cartridges/SRL files that allow you to update or downgrade an IS-TWL-DEBUGGER. These were mainly used for development consoles, and they do not work on retail units.

Features

The features for this cartridge are very simple. The cartridge contains updates for all regions (including China and Korea since v1.4) and they will be installed when selected. When a region has been selected, all the data will be deleted from the NAND and devsigned TAD's will be installed. Unlike regular TWL carts and exploits that do not have NAND access, this one does. If done correctly, the tickets, TWLCFG0.dat, TWLCFG1.dat and the system menu, with the bundled DSi applications have been installed. TwlNmenu and NandFiler are optional.

The cartridge can also detect if you're on a Panda or Debugger. If 16MB of memory is found, it will be listed as TWL CONSOLE (Panda, IS-TWL-CAPTURE). If 32MB of memory is found, it will be listed as IS_TWL_DEBUGGER.

Surface

On 09-02-2019, a user named Voodooween started DMing Trash_Bandatcoot about a specific TWL cartridge that can update to v1.4 and change regions. With no dumps being possible, Voodooween did send Trash_Bandatcoot screenshots to see the cart in action. At the time, both were not sure how the cartridge worked and how it operates.

On 1-5-2019, after conversations with d0k3, the creator of GodMode9, another user named Normmatt said that he has 3 SRL's versions, not only for v1.4a, but also for v1.4 and v1.3a. He also stated that the cartridge works on an IS-TWL-DEBUGGER and that it does contain devsigned TAD's. Later, the SRL files were made publicly.

Available versions

With the updater comes a HTML file for instructions and troubleshooting. On the bottom of the page is a changelog listed.

Notes

• Holding SELECT and A at the same time when continuing an update skips the installation for TwlNmenu and NandFiler.
• Instead of the version number being (eg.) v1.4E, it says v1.4E_dev, notifying you it has been updated using a SystemUpdater cartridge.
• The dev-version cannot import or export .bin files from the system settings like a retail unit. It can only delete applications, therefore, TwlNmenu must be used.
