So count this to one of those strange things that happen to Android devices, a T-Mobile Samsung Galaxy Note 5 getting updated to Android 6.0 Marshmallow way ahead of everybody. Samsung or T-Mobile haven’t even announced anything close to a Marshmallow update for the Note 5 phablet, but here we are. The circumstances for getting the update are strange to begin with, but the user has downgraded and updated a number of times. It is not a dream.
XDA member “danon.brown” has a Samsung Galaxy Note 5 on Lollipop that has a broken IMEI – that is to say, at some point in time, his EFS got corrupted and it caused his IMEI number to be corrupted as well. But no worries, he’s just using it as a wifi phablet anyways. Much to his surprise, his T-Mobile phone started updating on Nov. 15, straight to Marshmallow.
Reading the thread, it almost feels like an urban legend, but it’s not. The user’s phone has been downgraded a number of times, and it still proceeded to update to Marshmallow. At this point in time, system dumps and the update itself have been extracted, and some other users have used the update files to flash it on their own T-Mobile Note 5’s as well.
Suffice it to say, there are more than one Samsung Galaxy Note 5’s out there running on Marshmallow, and since the update and system dump files have been given to custom ROM cookers, expect a flashable Marshmallow ROM to come out pretty soon for the Samsung Galaxy Note 5.
