Moto G XT1032 5.1 GPE- How Do I Flash Stock?

[Dnlz]

XT1032 5.1 GPE to stock?

I'm trying to flash the stock 5.1 rom on my XT1032, but I get lots of errors since I'm new to flashing roms.
Could anyone explain to me how I can revert to stock? I flashed 5.1 GPE over 5.0.2 a few days ago but I kinda miss the Equalizer and the Moto Gallery. I tried flashing several zips to get the gallery but no success.

Thanks in advance.
