I think you are confused. The spes has no recovery partition; custom recoveries cannot be flashed in fastboot. Certain ROM's have incorporated them, like crDroid, but the steps to change to TWRP on spes do not work. You can boot to TWRP, but the 3 methods within TWRP to make it permanent all fail me... I get booted back to fastboot instead of recovery or system.Sorry for delay, I can only respond once at day. ADB sideload only works with zips, not with images, anyway, it fails, you always can use fastboot for flashing the recovery that actually works fine. If you are doubting how to get that recovery you actually have, take a backup from it, then transfer to the PC (for example), then change the extension to img, to the file, then you can use it through fastboot at any time.
