Launching rxTools without needing WiFi or Cubic Ninja - MSET!
All users -
Want to launch rxTools via MSET so that you don't need to connect to the internet? You can either:
Download
this version of rxTools 3.0 beta 8
If your system version is already on 4.X or 6.X, you do NOT need to do the following lines: 1, 2, 3, and 7.
If you are on 4.X, select the 4.X MSET option in line 7 and 9.
If you are on 5.X, follow all the instructions except use the 4.X MSET instead of the 6.X MSET in lines 2, 6, 7, and 8
1. Go
HERE. Name of the thread is "[MEGA] [CIA/BIN] MSET 4.X & 6.X backups, Browser backups, Update packs (All Regions)").
2. Download the 6.X-msetdg for your region (in .bin format)
3. Inside will be a msetdg.bin, put it on your 3ds sd card root
4. grab the rxtools.dat from the beta 8 and replace the one on your 3ds sd card
5. On your sd card, delete the "rxtools" folder, and put the rxtools folder from the download onto the root of your sd card
6. If you don't have a DS flashcard: grab the code.bin for rxTools from the "mset" folder and put it on your sd card root.
- If you do have a DS flashcard, you only need the rxCakeROP.nds or rxinstaller.nds on your DS flascard's sd card. Then you would put the flashcard in your 3ds, launch it, then run the rxCakeROP.nds or rxinstaller.nds file and install the 6.X MSET (Install the 4.X MSET if you are on 4.x system version)
-Note: the "DG" beside the system version number means "downgraded". So if you are on 9.x using the 6.x mset, you would use "6.x DG". If you are on 6.x system version, you would use simply "6.x"
7. Launch rxTools through the browser and hold R to open the menu. Go to Advanced Options, then Downgrade MSET. Turn off your 3DS afterwards.
8. If you used a DS flashcard in step 6, then skip this step! In the mset folder, open the QR Code named "URL-5.X-6.X-7.X-8.X-9.X" and scan it on your 3ds. Wait for a bit (it should crash and send you back to the home menu). If it doesn't crash after a minute, press HOME and it should crash.
9. Now you can launch rxtools by going to System Settings-> Other Settings-> Profile-> Nintendo DS Profile
