I have this phone, BQ Aquaris E4.5
https://tweakers.net/pricewatch/434564/bq-aquaris-e45-ubuntu-edition-zwart/reviews/
And at the moment I have android 5.
However I want to update to Android 6.
On the official page of the manufacturer I see http://www.mibqyyo.com/en-download/categorias/aquaris-e4-5/
However I see update for BQ Aquaris A4.5

Do you think If I try to update the firmware, the phone will break ?
