   MEMORANDUM

Sergio Leyva-Solano appeals the sentence imposed following his guilty plea to unlawfully entering the United States after having been previously deported in violation of 8 U.S.C. § 1326, and imposed following the revocation of his supervised release.

Leyva-Solano’s Sixth Amendment challenge to his sentencing enhancement under U.S.S.G. § 2L1.2(b) remains foreclosed after United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). See United States v. Moreno-Hernandez, 419 F.3d 906, 914 n. 8 (9th Cir.2005) (explaining that a district judge’s enhancement of a sentence, based on the fact of a prior conviction under U.S.S.G. § 2L1.2, does not raise any Sixth Amendment problems).

Because Leyva-Solano was sentenced under the then-mandatory Sentencing Guidelines, and we cannot reliably determine from the record whether the sentence imposed would have been materially different had the district court known that the Guidelines were advisory, we remand to the district court to answer that question, and to proceed pursuant to United States v. Ameline, 409 F.3d 1073, 1084 (9th Cir.2005) (en banc). See Moreno-Hernandez, 419 F.3d at 916 (extending Ameline’s limited remand procedure to cases involving non-constitutional Booker error).

REMANDED.
