Once a flashcart has been flashed with **ntrboot** it is typically no longer usable as a DS flashcart (with the exception of certain flashcarts such as the Acekard 2i). It is possible to restore a flashrom file back to an ntrboot compatible flashcart to return it to it's previous functionality. If you followed the ntrboot guide, you should have a copy of the flashrom backup.
### Required hardware
To remove ntrboot from your flashcart you will need:
- A flashcard that has been flashed with ntrboot
- A hacked DSi/3DS running ntrboot flasher in order to restore the flashrom backup to the flashcard
- A flashrom backup of your flashcart. If you followed the ntrboot flashing guide, you should have this as a `.bin` file in the `ntrboot` folder from your flashcart MicroSD card or DSi/3DS SD card
- If you do **not** have this backup, you may download the corresponding flashrom backup for your flashcart from the [3ds.hacks.guide ntrboot guide](https://3ds.hacks.guide/installing-boot9strap-\(ntrboot\).html#section-v-removing-ntrboot). These are available as magnet links and require torrent client like [qBittorrent](https://www.qbittorrent.org/download.php) or [Deluge](http://dev.deluge-torrent.org/wiki/Download) to download them

1. Place your flashcart's flashrom backup in the `ntrboot` folder on your DSi SD card. Create this folder if it does not exist
2. Download the [ntrboot flasher](/assets/files/ntrboot_flasher_nds.nds) to anywhere on your SD card
3. Insert your SD card into a modded DSi, then run the ntrboot flasher
4. Follow the instructions on screen. Select your cartridge from the list, then choose the `Restore Flash` option. After the restore has finished, your flashcart should now work as a DS flashcart again

1. Place your flashcart's flashrom backup in the `ntrboot` folder on your 3DS SD card. Create this folder if it does not exist.
2. Download the [ntrboot flasher](/assets/files/ntrboot_flasher.firm) to your SD card as `sdmc:/luma/payloads/ntrboot_flasher.firm`
3. Insert your SD card into a modded 3DS. Power on your 3DS while holding `START` to open the luma chainloader, then select the ntrboot flasher
4. Follow the instructions on screen. Select your cartridge from the list, then choose the `Restore Flash` option. After the restore has finished, your flashcart should now work as a DS flashcart again

### Troubleshooting
In some cases, the restore may fail. This may be due to either an incorrect flashrom backup file, or your flashcard may be incompatible with the restore. ntrboot uses a hardcoded name for restoring flashrom backups. If you renamed the `.bin` file and do not have the original name, you can create a flash dump which will create a `.bin` file of the correct name of which you can then use to rename your flashrom backup.
