Install unlaunch on development units (pandas)

This goes without saying, but BACK UP YOUR NAND FIRST! Backups are especially important with rare hardware like this.

For reasons beyond my head, unlaunch will fail to uninstall on dev units. It sounds like it's something to do with exploitable titles blanking out a register and unlaunch not being happy with it. Thankfully you don't need exploitable titles on dev units!

  1. Download a DSiWare type homebrew capable of booting an SRL off of the SD card. I suggest godmode9i
  2. Download maketad.exe. This can be found in any copy of the TwlSDK (TwlSDK/tools/bin/maketad.exe) or your favorite archive of dsi development and factory software (you should probably put exactly those last 7 words into google)
  3. Run maketad like so, replacing "input SRL" with the path to your homebrew: maketad.exe <input SRL> -s -o program.tad
  4. Copy program.tad to your DSi SD card
  5. Download and copy the latest unlaunch to your SD card
  6. Boot TwlNmenu on your DSi and install program.tad
  7. Boot your newly installed program and use that to launch unlaunch
  8. Install unlaunch
  9. Sucess!

tl;dr boot a copy of unlaunch from an installed homebrew (specifically set as a system app for full NAND access) and don't use exploits.

If you're wondering why this guide doesn't install an unlaunch TAD directly, unlaunch is missing the TID needed for maketad. Hex editing is a bit too complicated for some people, so using another app to boot just makes more sense.

WARNING: Unlaunch sets the launcher as read only, so you'll need to uninstall unlaunch in order to update via TwlSystemUpdater or TwlNmenu.

    That's a relief to hear. Do you know what happened?

    @BakerMan, Any idea what happened? I hope that your brother's doing good.
  • BakerMan @ BakerMan:
    Well, from what I've heard from my parents, he had a seizure last night, perhaps an epileptic episode, fucking died, had a near death experience, my dad called the paramedics, they showed up, took him to the hospital, and he woke up covered in tubes, and started complaining.
  • BakerMan @ BakerMan:
    He couldn't eat until after his MRI, when he had a bomb pop.
  • BakerMan @ BakerMan:
    What matters now is that he's doing alright.
  • Veho @ Veho:
    But you still don't know what it was?
  • Veho @ Veho:
    Has he had seizures before?
  • The Real Jdbye @ The Real Jdbye:

  • The Real Jdbye @ The Real Jdbye:
