is it necessary to flash OOS 2.1.X first?So, finally we got Marshmallow.
Excuse my ignorance, but i am a bit confused how to upgrade from CM. Without bothering anyone, can you eplain how to update safely?
From what i've read the are the steps:
flash stock recovery via TWRP
flash OOS 2.1.X first
flash OOS 3.12 now
flash TWRP v41 by eng.stk via fastboot for future upgrades or kernel istallations (this step is optional)
Is that right?
