Downgrading back to 2.17 from MicroSD?

[aznmode]

I might be mistaken but I thought the Sd card method works on all bootloader. however I know for sure it will work with olipro 2.40. Search for the HARD SPL unlocker. Run it completely and let it load on your phone. You should then be able flash with any nbh in the card. I have 2.17.nbh and 3.16.nbh stored in my PC and I can copy either to the card and rename it to TITAIMG.nbh. Put my phone in bootloader mode (hold power and camera while rebooting) and it always flashes no problem.
