Please provide frequent updates for Xolo Era 4k .....
All my friends' phones are getring Marshmallow and Nougat updates. Please provide it for Xolo phones also. I really need it !!!!
Unfortunately, there's still no official Marshmallow nor Nougat update for your phone. Zrana is correct, your only way as of now is through a custom rom.
One way to update with Marshmallow is through custom ROM.
