Download Galaxy S2 Marshmallow Update: CM13 and other ROMS


Page content:

Yessss!! Marshmallow update for the Galaxy S2. it’s the best update for the best Android device to date — for me, personally — in the at-its-time manner. Official updates have not taken S2 beyond Android 4.0 Ice Cream Sandwich, but unofficial love continues to shower upon — quite deservedly — the device. Here we are, with the Android 6.0 update for Galaxy S2 in the form of some popular custom ROMs.

We’ve got the Galaxy S2 CM13 ROM below, as well as other ROMs that provide feature or ten more than CM13. As all are free, which you must know by now for sure, go ahead and try them all out, giving each ROM at least 3-4 days to make its case.

With 1GB RAM on board, you can’t expect the Galaxy S2 to run the show on Marshmallow update without stopping to catch a breadth here and there, but it should do well. Minimum requirements hasn’t changed till date since Lollipop, and it’s still 1GB RAM.

We’ve cover Marshmallow custom ROMs for not only the international Galaxy S2 (model no. GT-i9100), but also for AT&T Galaxy S2 (SGH-i777) and T-Mobile Galaxy S2, Hercules (SGH-T989).

With the Android 6.0 update for Galaxy S2, you will be able to use the famous Doze mode, greater app permissions, better app control and much improved battery life than current one. Also you get to sue stock UI on your Galaxy S2.

Running the latest Marshmallow OS on five year old device in current times when tech is rapidly advancing is darn exciting thought. We also have our Galaxy S2 lying somewhere and it’s about time we looked for it and gave it a new lease of life.
