Android 6.0.1 Marshmallow stock firmwares have begun to roll out. If you are rooted or need to upgrade manually (using ODIN and stock firmware, follow our unroot directions), you can grab these stock firmwares yourself and flash. Please see updated Marshmallow stock firmwares on our Galaxy S6 Edge stock firmwares. If you are rooting and installing custom ROMs, it may be a good idea to always have the original copy of the stock firmware for your model of Galaxy S6 Edge handy just in case something goes wrong (that way it will save you time to restore your phone). Also, rooting the Marshmallow stock firmwares can be seen here.
For those of you who are rooted or didn’t receive the Android 6.0.1 Marshmallow update on your Galaxy S6 SM-G920F model, you can update manually using ODIN and stock firmware (see our unroot guide here).
For those of you who want to root your Samsung Galaxy S6, S6 Edge, or even Note 5 on latest Android 6.0.1 Marshmallow, you can do so using SpaceX kernel.
