Miraclebox Ultra stuck on Booting

[Tunder]

Hello Friends
I need you help on how to recover this receiver, Its been a good receiver so far until recently, I was playing around with multiboot, I decided to switch to another image and it got stuck on booting, I try to flash the receiver with another image but is not recognizing the USB with the new image, it goes to booting and stays there.
I seen recovery procedures using Putty, may be this is the last resort, if it is please guide me to one of these procedures.
Any Ideas will be appreciated.
Regards.
Tunder

Try flashing the newest bootloader

You flash the bootloader exactly the same way as you would flash an image.
