Cisco EPC3925

BCM33xx

This is a DOCSIS 3.0 Wireless cable Residential Gateway. It uses an eCos operating system. It seems it shares the same hardware with the Netgear CG3100D/CG3101D, Motorola SBG6580, Virgin Media Super Hub VMDG480.

There exist GPL sources available from Netgear FTP:
CG3100_GPL_src.zip eCos source code (38 MB)
CG3100Dv2_V5.5.5.83.mp2_LxG1.0.5.83.mp2_EU_src.zip eCos and Linux source code

visit Netgear FTP, models CG3xxx seems to share similar hardware

There might be some more information about the bootloader, creating images, etc at https://github.com/Broadcom/aeolus from Broadcom. Its about the BCM3384, which might share some internals with the BCM3380

Writing a new bootloader:

CM/IpHal> bootloader

ERROR - required parameter ( IpAddress) was not specified!

COMMAND:  bootloader

USAGE:  bootloader  [-f] IpAddress Filename{255}

DESCRIPTION:
Downloads the specified bootloader image from the TFTP server and stores it
to the bootloader region.  The image must be valid for the platform, and must
have a ProgramStore header (but no compression).

EXAMPLES:
bootloader 11.24.4.3 bootloader3360_2_1_2_c0.bin     -- Upgrades the
                                                        bootloader.
bootloader -f 11.24.4.3 bootloader3360_2_1_2_c0.bin  -- Accepts a bootloader
                                                        with non-matching
                                                        signature.

or a new image file

CM/IpHal> dload

ERROR - required parameter ( IpAddress) was not specified!

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.

Debricking

generic.debrick

To unbrick your device, you need a valid bootloader and a valid image. The bootloader is 64K and should be flashed at address 0.

ADVICE: Make a backup of the bootloader and image first before attempting an erase/write!
