My sony walkman nwz b133f(b) wont start. when on, it says boot error... what should i do? do u have the firmware availble that i can download myself?

tried this and it worked, thx. but I had to do another step before the first firmware update - press and keep pressed the "vol -" button on the walkman while inserting it into the USB port and keep pressed until the nwz-b100 update program recognizes the walkman (and by the way it was nwd-b100 V1_3, and not nwz-b100 V1_3) tried this and it worked, thx. but I had to do another step before the first firmware update - press and keep pressed the "vol -" button on the walkman while inserting it into the USB port and keep pressed until the nwz-b100 update program recognizes the walkman (and by the way it was nwd-b100 V1_3, and not nwz-b100 V1_3)

almost worked for me, just had to do an additional step before the first firmware update:
press the vol- button while inserting the walkman into the usb port and keep it pressed until the update program recognizes the walkman
and by the way, it is not nwz-b100 V-1.3 but nwd-b100 V-1.3, but Muhammad Idham posted the correct firmware link anyway... almost worked for me, just had to do an additional step before the first firmware update: press the vol- button while inserting the walkman into the usb port and keep it pressed until the update program recognizes the walkman and by the way, it is not nwz-b100 V-1.3 but nwd-b100 V-1.3, but Muhammad Idham posted the correct firmware link anyway...
