Backup firmware getram cfe getram kernel getram nvram getram cfe save 9fc00000 400000 (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 detect tap c tap a ffffffff (You should now see "DEBUG ON" on the lower right coner). detect (You should now see the flash type. If not start over again. ldram cfe erase cfe sprogram cfe (I found slow program works better than the normal program on this modem. Possible because of the watchdog). erase kernel sprogram kernel erase nvram |
