Inside that pack have the market (vending.apk), you forgot they there or rly need apply with language pack?
I've flashed the Vivo Leak and got the pt-br (Portugues Brasil) and es-mx (Español Mexico) language files. Just apply the attached update.zip file and you're good to go!
EDIT: Reported that vending.apk was included in the update.zip file. I mistakenly forgot to remove it. Uploaded new update.zip pack. The attached file is the right one with only tts files from Voice Commands.
