Have you tried the Nokia product support tool for store, that comes with the Nokia Care Suite. With that you can download the firmware with the respective product code which you can find it here.

Dunno if Nokia product support tool for store is still working for downloading roms, but is worth a look.

And here in WPC forums someone have the mexican L920 white Country Variant rom which is essentially a carrier free version of the rom and it seems is willing to upload that file to Mega. Ask Ripper Cornelio user about that.
