Recently, a leaked Samsung document had revealed that the Galaxy Note 5 and Galaxy S6 Edge+ users are going to receive Android 6.0 Marshmallow in the next month. Its arrival seems close at hand as an owner of Galaxy Note 5 on T-Mobile has claimed to have installed a rogue edition of Android 6.0 update.

Danon, a T-Mobile Galaxy Note 5 user has revealed on XDA Developers that when he encountered an issue with the IMEI number of his handset, he installed the stock firmware by using the Samsung Odin tool. The software update installed the Android 6.0 Marshmallow update on his device.

According to TMO News, the System Update that Danon performed should have installed the N920TUVU2COJ5 software version. However, instead of it N920TUVU2DOK5 update was installed that brought Android M to his Note 5.

Danon has also uploaded several photos of the Android 6.0 MRA58K.N920TUVU2DOK5 build that he installed on his handset. The publication has reported that it is the same software update that was also made available to Nexus 5, Nexus 6 and other Google Nexus devices in the recent past.

Danon had installed the stock firmware to fix the issue associated with the IMEI number. However, even though he managed to install the rogue build of Android 6.0, he was unable to resolve the IMEI issue.

The official release of the Android M for Galaxy Note 5 handsets is imminent since the user managed to accidentally install the update. The leaked Samsung document revealed by Times News also suggested that the estimated timeframe for the roll out of Android 6.0 for Galaxy Note 5 and Galaxy S6 Edge+ is December. Hence, it is very likely that both the handsets may be blessed with Android M within this year.

The Samsung Galaxy S6 and Galaxy S6 Edge are slated to get Android M by January 2016 whereas the Galaxy Note 4 and Galaxy Note Edge are expected to receive the Android upgrade by February 2016. The exact timeframe of Android 6.0 roll-out for Galaxy S5, Galaxy Alpha, Galaxy A8, A7, A3, E7 and E5 handsets is currently unavailable.
