### קריאה דרושה

safecerthax is compatible with all Old 3DS and Old 2DS devices in all regions.

If your (Right/Left Shoulder), (D-Pad Up) or (A) buttons do not work, or your ISP is rerouting DNS changes, you will need to use an alternate method, like [Installing boot9strap (Browser)](installing-boot9strap-(browser)).
{: .notice--warning}

This exploit will not work on the New 3DS, New 3DS XL, or New 2DS XL. Please ensure that the device you are modding is an Old 3DS, Old 3DS XL, or Old 2DS before continuing.
