Your highness, we’ve just secured a TWRP flashable zip file of Android 6.0 update, so that you don’t have to burden yourself with installing stock recovery back to install an Marshmallow OTA update (click the link to get OTA zip).
With this, you can flash the Marshmallow update using TWRP itself. The update is completely stock, save for the tweak that was required to make it work with TWRP.
Hence, the Marshmallow update for Android One Sprout4 devices we have here is unrooted. But do make sure that you are on Android 5.1.1 update, with build no. exactly LMY48M, as this is the base required by Marshmallow update.
Compatible devices (Sprout4)
- Micromax Canvas A1
- Karbonn Sparkle V
- Spice Dream UNO
- MyPhone Uno
- Symphony Roar A50 (8GB variant only)
- Marshmallow update for Android One Sprout4 devices — Link | File: update.zip (338 MB)
