how do i get the hitachi back to 1.4 i have it back to stock but when i try to flash it gives message cant open 1.51 i have took the 1.51 out of the j/f firmware folder and put the 1.4 in but no go do i need to use an older version of j/f thanks

does jf say firmware cant be loaded even tho its in the firmware folder?when it does this to me i just selct the firmware file manually..make sure its the correct drive revision and you should be good to go..let me know how you get on
