If you have already hacked your device before and have a EmuNAND based CFW setup, this guide deals exclusively with SysNAND and you should follow all instructions from within or applying to SysNAND. Σημειώστε ότι οι όροι EmuNAND και RedNAND αναφέρονται σε ελαφρώς διαφορετικές υλοποιήσεις [της ίδιας έννοιας](http://3dbrew.org/wiki/NAND_Redirection).
{: .notice--info}
If you downgrade to 2.1.0 on a 2DS or New 3DS and leave Wireless Communication off, you can re-enable the wireless by removing the battery and unplugging the charger for several seconds then booting back up.
{: .notice--info}
If you've been using the New 3DS's microSD Management to transfer files to your SD card, this will no longer work on 2.1.0. Βεβαιωθείτε ότι έχετε μια μονάδα ανάγνωσης κάρτας microSD διαθέσιμη πριν συνεχίσετε.

To use the [magnet](https://en.wikipedia.org/wiki/Magnet_URI_scheme) links on this page, you will need a torrent client like [Deluge](http://dev.deluge-torrent.org/wiki/Download)
{: .notice--info}
**For now, connecting your device to the internet is REQUIRED to continue after the 2.1.0 CTRTransfer.**
{: .notice--warning}
**Disable the parental controls of your device before doing the 2.1.0 CTRTransfer. Εάν δεν γνωρίζετε τον κωδικό, επισκεφθείτε αυτή την ιστοσελίδα [this](https://mkey.salthax.org/). Εάν δεν μπορείτε να απενεργοποιήσετε τον γονικό έλεγχο επειδή το συνδεδεμένο NNID είναι για παιδί κάτω των 13 ετών μπορείτε αντί γι΄αυτό να ορίσετε όλες τις επιλογές του γονικού ελέγχου σε "do not restrict".**
{: .notice--warning}
**Performing a CTRTransfer will remove all user-installed tickets (which allow access to games) from your device until the created backup is restored.**
{: .notice--danger}
**Ποτέ μην πραγματοποιήσετε μορφοποίηση σε ένα 2DS σε έκδοση <6.0.0, αλλιώς δεν θα μπορέσετε να πραγματοποιήσετε την αρχική παραμετροποίηση, το οποίο θα οδηγήσει σε ΑΧΡΗΣΤΕΥΣΗ ΤΗΣ ΣΥΣΚΕΥΗΣ ΣΑΣ!**
{: .notice--danger}
**Ποτέ μην ενημερώσετε ένα New 3DS το οποίο τρέχει την έκδοση 2.1.0 (μια έκδοση του Old 3DS) αλλιώς θα οδηγηθείτε σε ΑΧΡΗΣΤΕΥΣΗ ΤΗΣ ΣΥΣΚΕΥΗΣ ΣΑΣ! You MUST restore a NAND backup or CTRTransfer back to standard New 3DS firmware first!**

**Putting a New 3DS on 2.1.0 in sleep mode is known to cause a BRICK!**
**This only happens when shutting the lid _while your device is on_; this does not apply to turning your device off.**
**Your device only enters sleep mode when the lid is closed. Δεν έχει καμία σχέση με χρονόμετρο ή κάτι παρόμοιο.**
**Μόλις βρεθείτε στην έκδοση 2.1.0, συστήνεται να συνεχίσετε χωρίς καθυστέρηση για την αποφυγή ενός τέτοιου γεγονότος!**
In this section, we will be flashing your device's [CTRNAND](https://www.3dbrew.org/wiki/Flash_Filesystem#CTR_partition) partition to 2.1.0 in order to take advantage of an oversight in 2.1.0 for the purpose of extracting the [OTP](https://www.3dbrew.org/wiki/OTP_Registers) unique to your device. Αυτό το αρχείο OTP είναι απαραίτητο για την εγκατάσταση του arm9loaderhax, και **δεν είναι δυνατόν** να μοιραστεί με άλλες κονσόλες.

This is accomplished by [installing a premade CTRTransfer image](https://www.reddit.com/r/3dshacks/comments/4zhe4a/) containing 2.1.0, copying your device specific files (such as `moveable.sed` and `SecureInfo_A`) to it, then fixing the title databases.

#### Οδηγίες
##### Ενότητα I - Προετοιμασία
1. Power off your device
1. Εισάγετε την κάρτα SD στον υπολογιστή σας
1. Create a folder named `CTRTransfer` on the root of your SD card if it does not already exist
1. Copy the 2.1.0 `.bin` and `.bin.sha` from the CTRTransfer `.zip` to the `/CTRTransfer/` folder on your SD card
+ Make sure to try each URL if the first one doesn't work (some versions cannot use the first one, and some versions cannot use the last three)
+ If you get an error, [follow this troubleshooting guide](troubleshooting#ts_browser)
1. If the exploit was successful, you will have booted into SafeCTRTransfer
##### Section III - CTRTransfer
1. Allow the SafeCTRTransfer initialization and safety checks to proceed automatically
+ If you get an error, ensure you have all files in the correct locations and that you have enough free space on your SD card as detailed in [Get Started](get-started)
1. When prompted, input the key combo given to confirm CTRTransfer to 2.1.0
+ This process will take some time
+ This process will automatically create a backup of your device's NAND at `/CTRTransfer/<serialnumber>_nand.bin`
+ If you get a critical error, [follow this troubleshooting guide](troubleshooting#ts_transfer)
1. Once this process has completed, remove your SD card from your device to reboot
+ The reboot will take about 2 seconds to trigger
+ While on 2.1.0, your device will black screen on boot if your SD card is inserted before the home menu loads
+ Every time your device is rebooted on 2.1.0, you will need to take out your SD card before boot and put it back in after the home menu loads
+ For now, leave your SD card out as you will be copying files to it in the next page
+ Το παραπάνω πρόβλημα θα διορθωθεί με την επαναφορά της συσκευής σας στην επόμενη σελίδα
