downgrade boot loader on moto v975
 

hi guys, I have to downgrade the bootloader on a v975 from 6.12 to 5.f.1, how can I do?

i don't have smart clip or other professional tools, i only have usb-smart but is not activated yet for motorola (I will acrivate it as soon as possible 'cause is cheap and gives acess to the support area with moto firmwares etc..) and now I need a free method do downgrade the bootloader... can someone help me?
