Firmwares For Conexant CX82310 Based ADSL Router

After successfully unbricking the Aztech DSL305E ADSL modem, which is a Conexant CX82310 based ADSL router, I realized the firmware that I used for the job was quite old and not up to date, this triggered my obsession to search for the newest firmware for this beast, so I did a little digging around at Aztech's site and some others, the results are as follows:

Aztech's
Their web support page no longer put up any links to firmware download for both DSL305E & DSL305EU, may be there were too many people having their modem bricked after uploading their firmware using modem's web manager, this is especially true for these type of modems if firmware updates through modem's web manager are not following incremental sequence from lower to higher version and jumping or skipping version in between, this will definitely results in error and a bricked modem!!
Anyway the firmwares for DSL305E/EU are still lying around inside their FTP site and it took some effort to figure out which is the most latest one.

Firmware Update Notes
a) Firmware updates via router's web manager must follow incremental sequence from lower to higher version, otherwise jumping or skipping version in between will results in error and bricked modem!!
b) Firmware updates via USB flash is the safest and foolproof method provided that the USB flash programmer is bundled with the firmware package.
c) Firmware package with bundled USB flash programmer can be use for both non USB type modem and USB type modem.
d) A special USB cable is required to flash write the firmware for non USB type modem without an external USB-B connector but with an internal USB header connector (e.g. Aztech DSL305E, refer to my previous blog post).

Repair Guide

Conexant CX82310 Based ADSL Router Repair Guide
The following symptoms will indicate a bricked router with corrupted flash memory:-
a)	After power on, only Power & LAN lights are lit.
b)	DSL light stays off & no blinking.
c)	No response to http/ftp/telnet/ping to 10.0.0.2.
d)	Reset button not working.
In this case you will have to do an USB firmware flash in order to fix it.
You will need:-
1.	A PC with an Intel or Via chipset (Intel is best) mobo with on board USB ports running a processor speed of 900Mhz or less and Win9x/WinNT/Win2K/WinXP OS.
2.	A cross/Philips head screwdriver to open the router's casing.
3.	For router without an USB-B receptacle; A special USB cable to connect the router's internal 10pins (based on Aztech DSL305E's J7) USB header to the PC's USB-A port. For router with an USB-B receptacle; A standard USB cable to connect the router's USB-B port to the PC's USB-A port.
4.	A jumper block like the ones used on the back of hard drives.
5.	A firmware package bundled with USB flash programmer.
Stage-1: Cracking open the router
1.	Unplug all cables from you router, turn it upside down and lay it on a flat surface.
2.	Unscrew any screws that you can see, if not then look for any small round rubber feet, gently pry them off with your fingernail or flat-blade-screwdriver, you will find the screws hidden under them.
3.	Turn the router back up right and carefully pull the two halves of the router casing apart, the circuit board should sit flat on the bottom casing.
Stage-2: Add jumper & connect router to PC
1.	Discharge any static electricity from your body by touching something earthed like a PC's exposed (not painted over) back panel metal casing.
2.	Locate a barcode sticker label with MAC address above or under the circuit board or under the bottom casing, note down this router's MAC address for later use.
3.	Locate the jumper pins (pair) on the circuit board, the pair should be situated near to the small shiny metal component (clock xtal), place the jumper block onto the pins, try to avoid touching any of the circuit.
4.	Disconnect all USB devices or plugs from your PC's USB ports.
5.	For router without an USB-B receptacle; Insert the special USB cable's 10pins socket to the 10pins (based on Aztech DSL305E's J7) USB header on the circuit board, make sure the pin #1 of the header is aligned with the triangular mark on the socket, plug the other end of the cable into one of your PC's USB ports. For router with an USB-B receptacle; Insert a standard USB cable's square plug into the USB socket on the router and plug the other end of the cable into one of your PC's USB ports.
Stage-3: Flash the router
1.	Make sure the router's circuit board is lying flat on the bottom casing.
2.	Connect the power cable to the router and switch it on, make sure the POWER light comes on.
3.	Boot up the PC into pure DOS mode.
4.	At DOS prompt, change directory to where the firmware files and USB flash programmer utility are located.
5.	For router without an USB-B receptacle; Type "rm.bat" & [Enter] at the DOS prompt and wait for further instruction. For router with an USB-B receptacle; Type "rm_usb.bat" & [Enter] at the DOS prompt and wait for further instruction.
6.	When prompted for "Start Ethernet Global Mac", type in the router's MAC address (the one you took from the barcode sticker label) & [Enter], e.g. 00-09-F3-00-DB-1D.
7.	When prompted for "End Ethernet Global Mac", type the same MAC address as before but change only the last byte to FF & [Enter], e.g. 00-09-F3-00-DB-FF.
8.	When flashing is over, take note on the final messages on screen, make sure there is no error messages and the DOS prompt returns.
9.	Wait about 1 minute, then power off the router and PC.
Stage-4: Reconnect the router as before
1.	Remove the power cable, USB cable and jumper block from the router.
2.	Do the reverse process of the router casing opening procedure.
3.	Connect the power cable and DSL phone line back to the router, then connect the router back to the PC via LAN/USB.
4.	Power on the router and make sure the POWER light comes on, wait about 1 minute.
5.	If the flash process is successful, the DSL light should start blinking within 1 minute from power on, it will change to solid if connection to DSLAM is established.
6.	Power up the PC and boot it into windows mode, make sure you can open the router's web configuration page.
