Bērziņš was initially given a suspended sentence of 20 months, which turned into a real one after he failed to comply with probation rules.
He is to be imprisoned until November 30, and the two months he spent in a Czech prison have been included in the time being served.
The request for early release on probation was turned down after Inga Stupele, a probation official at the Latvian Prison Administration, told the court she doesn't support early release as Bērziņš is not repentant.
During his imprisonment in Latvia, a phone was found among his stuff, a violation of prison rules.
"You can kill me, but I will never admit that I've carried out a serious crime. Because it's not even a crime. It's tiny misdemeanor," Bērziņš said.
His lawyer Jānis Mucenieks said the ruling will be appealed as soon as it's published.
