Yes , you can use it as FOTA recovery , but it doesn't works in this kernel , it will just boot to black screen instead.yes, I wouldn't be able to run it if I didn't
edit: can I use the recovery you posted before like fota recovery? because fota recovery works, you only must have recovery built with 3.10 kernel otherwise you have no display.
It works flawlessly with cm 12.1 kernel
