 Here is a good source to find how to open the box.

Definition Commands (usbjtag NT 0.08 and up):

Backup firmware
getram cfe
getram kernel
getram nvram
getram cfe
save 9c000000 800000
(Note, I recommend you do cmpram after getram. eg.
getram cfe
cmpram cfe
This is because the watchdog might cause the getram to get the wrong data).

Drbrick the device. (Must use 0.08 and up. This is used when detect give you 0xffff,0xffff or 0x0000,0x0000 as flash type
