Here is just another way to update your firmware, it only requires a tftp server and you must have a shell firmware installed.
1.change your ip to 192.168.100.10/255.255.255.0
2.start up your tftp server and make sure it is hosting the firmware.hex.bin to be flash
3.telnet your modem and type this cmd: dlfile
you will be prompted to enter the tftp ip, which will be 192.168.100.10 ,then prompted again for the firmware name, which will be the exact name firmware.hex.bin that you are hosting on your tftp server. Now you will see the some code being executed and see the tftp transfer happen, do not interupt this process!! the modem is writing the firmware to flash and will reset/reboot itself..your new firmware is now installed.
update:
Usually this command will work properly.
dload -f -i 1 192.168.100.10 firmware.bin
CODE
COMMAND: dload
USAGE: dload [-i Number] [-l] [-f] IpAddress Filename{255}
DESCRIPTION:
Downloads the specified s/w image from the TFTP server and stores it in the image slot specified. The image must be valid for the platform, and must not contain any security, encryption, or digital signatures. It must be a simple image file with only the normal ProgramStore compression header. Parameters:
-i — Specifies the image slot to store the image to.
-l — Allows a large image to be stored, spanning images 1 and 2, if
allowed by the flash driver configuration.
-f — Forces the given image to be accepted, as long as the CRCs are
valid.
Note that you must always specify the TFTP server address and filename; unlike the dload command in the Docsis directory, this command doesn’t make use of any Docsis-specific nonvol settings, so it can’t remember the last values used.
EXAMPLES:
dload 11.24.4.3 vxram_sto.bin — Stores the image to the default image slot.
dload -i 1 11.24.4.3 vxram_sto.bin — Store the image to slot 1.
cd /doc
dload
COMMAND: dload
USAGE: dload [-i Number] [-s] [-l] [-f] [IpAddress] [Filename{127}]
DESCRIPTION:
Causes the CM DOCSIS Control thread to download and store the specified image file via TFTP from the specified TFTP Server IP address. When the download is completed, the next reboot will run this image. If you omit the filename and/or IP address parameters, then we will use the ones stored in non-vol settings.
The -i parameter specifies the image number to be overwritten
(number of images depends on the platform). If omitted then the default image for the platform will be used. If present, the -s causes Secure Download to be used. The -l flag selects image1 as the target and allows a large image to be loaded, if allowed by the flash driver. The -f flag forces the image to be loaded even if the signature or compression types are not valid for the platform.
EXAMPLES:
dload 11.24.4.3 ram_sto.bin — TFTPs ram_sto.bin from the server.
dload -i1 11.24.4.3 ram_sto.bin — Same, but downloads to image1.
dload — Uses the file/server from non-vol settings.
dload -s 11.24.4.3 ram_sto.bin — Secure download.
dload -l 11.24.4.3 ram_sto.bin — Download large image to image1.
dload -f 11.24.4.3 ram3360_sto.bin — Loads a 3360 image onto a 3345 modem.
