ctrcheck is a custom GodMode9 script that does a large number of sanity checks and checksums on a 3DS' firmware and SD card to make troubleshooting easier through fault isolation, though it can also automatically fix certain issues.

Required Reading

ctrcheck does not fix the majority of issues by itself, and instead only informs the user that they exist. Some of the issues it checks for may still require large amounts of knowledge to fix - this script is not a 'miracle cure' and should not be treated as such.

Additionally, ctrcheck cannot check whether the SD is damaged, only certain specific issues with reading its data. If you have an issue that might be caused by an SD being corrupted or formatted badly, the pages Formatting an SD card and/or Checking SD card integrity will be far more useful.

Instructions

What You Need

The latest release of ctrcheck.gm9
- To download, right-click/long-press the page and select Save page as... or similar, then rename the downloaded file to ctrcheck.gm9 if it is not already named that
A device that you can use to transfer files to your 3DS, either via an SD slot or via FTP

Section I - Prep Work

Power off your console and insert the SD card into your device
Copy the downloaded ctrcheck.gm9 into sd:/gm9/scripts on the SD card
If GodMode9 either is not installed or is outdated (the latest version is v2.1.1), install the latest version now
Reinsert the SD card into your console

Section II - ctrcheck

Hold START, and while holding START, power on your console. This will launch GodMode9
Press the HOME button, then go into Scripts... -> ctrcheck
- If ctrcheck does not appear here, enable file extensions and then make sure the name of the script is exactly ctrcheck.gm9
Based on the type of issue you're having, select one of the top four options
- If you are even slightly unsure about what type of issue it is, pick Full
Accept any prompts to fix issues and unlock sysNAND write permissions that appear, then read the results on the top screen once the script finishes
If you are following this guide at someone else's request, send a picture of the results to that person. Otherwise, if the results include any of the following, do the matching instructions:
- ______ installed to firm0/firm1: If the result type is Information, you may ignore this line. If the type is Warning or Critical, follow either Updating B9S (if using boot9strap) or Updating fastboot3DS (if using fastboot3DS) to get the latest version of a known good bootloader. If the type is Error, ask for help in the Nintendo Homebrew Discord
- Critical: NVRAM is inaccessible: If your console is an old model (no ZL/ZR shoulder buttons and no C-Stick), try reseating the Wi-Fi module on the motherboard. If this does not fix it or you have a new model, download the special build of Luma linked in the fourteenth word of this sentence, rename it to boot.firm, and put it on the root of your SD card
  - This build does not fix the issue, only stop it from causing system crashes. You will still be unable to play DS games, and if you were unable to use Wi-Fi it will also stay broken - fixing these entirely requires a hardware replacement
- Warning: The SD title database needs to be reset: Using this picture as a guide, reset the title database. After you reset, follow Finalizing Setup to reacquire the homebrew apps
- Warning: There is no boot.firm/boot.3dsx in the SD card root: Follow Restoring / Updating CFW to reacquire the file(s)
- Critical: NAND is unreadable at _______...?: Your console's internal storage is damaged in a way that may require advanced troubleshooting to fix. Ask for help in the Nintendo Homebrew Discord
- Bruh Moment: movable.sed is from Seedminer: You have made a mistake. Find your original movable and restore it to the folder 1:/private, or else uninstalling CFW will be guaranteed to brick your console. If you cannot find your original movable, ask for help in the Nintendo Homebrew Discord and provide every piece of context you know about this issue
- If any other result(s) of the type Warning, Critical, or Error appear, you may want to ask for help in the Nintendo Homebrew Discord and provide the full output of ctrcheck there

The results of this ctrcheck can also be found on the SD card in sd:/gm9/ctrcheck_latest.txt - however, if you run ctrcheck again, this file will be overwritten with the new results. If permanent logging was enabled, it will also be appended to the file sd:/gm9/ctrcheck_log.txt.
