Why Downgrade from Marshmallow 6.0?
While there are numerous reasons on why you need to downgrade from the current beta version of Marshmallow 6.0, there are no radically and mind blowing feature for which you may want to keep Marshmallow OS in your Nexus device unless you are a developer. Let’s check out some meaningful reasons for downgrade.
WIFI Mac Issue: In the latest Beta 3 release of Marshmallow 6.0, WIFI MAC address changes upon after every reboot.
Battery Drain and Heating Issue: Battery in Nexus 9 drains no less than water. For us in Marshmallow the device started heating which led to faster battery drain than in normal condition.
Force Close Issue: Even though it was a clean install, apps like twitter and Google Play Services are giving force close issues.
Pre Requisites before Downgrading from Marshmallow:
SMS – SMS Backup & Restore
Call Log – Call Log Backup and Restore
Photos, Music and Videos – Take manual backup in your computer,
App Data – App history can be found in Google Play Store but the downloaded data in your apps will be lost and will have to be downloaded.
Battery left in your device should be a more than 50%. Make sure that ADB is properly configured in your computer. Without this it’s not possible to perform this downgrade.
Let’s proceed to the next step we have mentioned steps to downgrade the OS in your device.
