Spice was kind enough to let us know beforehand that its Dream Uno (Mi-498) is in line for Android 5.1 treat, and well, today’s the day it started distributing the 5.1 OTA update. We’ve got the download link right below, which you can use to be able to manually install the update all by yourself, using the guide below, without waiting for your turn under age-old poor gradual rollout system. The build no. of the 5.1 update is LMY47O. Credit for capturing the OTA update for all of the community goes to cool buddy Lalit, called lalitcoolbudy over at the XDA.
