You need stock recovery, unmodified system and locked bootloader.
I cannot verify this as with my device I do not need a locked bootloader to flash an ota
I also can tell that the bootloader do not need to be locked for ota to install. You can be rooted and s-off, it will work also! The only requisite is to be on a stock rom odexed!
I restored the original saved rom, put back the 2.61 recovery: I could download the 2.61 ota, then the new 3.12.401.3 today, using it (with mandatory customization: supersu, xposed, sense 6 toolbox) 😊
