bricked actiontec gt724-wgr

[chrisonpumkinvine]

i have a actiontec dsl wireless router gt724-wgr,i tried to upgrade the firmware and it said it went ok but could not get internet connection so i tried recvery program that came with router and it said it did the restore but cannot get on internt.the power light is green and dsl light is green but internet light is not on.i tried to use recovery again and it says failed when trying to erase.is the modem bricked and if so can it be unbricked?

From what you say, the router appears to be bricked. Any bricked router can be unbricked if you have a functional firmware image and JTAG. I do not know the chipset in your router, but it does not appear to be AR7, so I cannot offer an opinion on how you might unbrick it. You might need to ascertain the chipset, and then search for forums on hardware using that chipset.

Try this with the single image firmware...

Note that for my Actiontec GT704, I used the following MTD setup before flashing the the adam2 4 port wireless image:

mtd0 0x90090000,0x90350000
mtd1 0x90010090,0x90090000
mtd2 0x90000000,0x90010000
mtd3 0x903f0000,0x90400000
mtd4 0x90010000,0x90350000

Set these MTDs with RRT.

I flashed with this image...

If the bootloader is fine, you can debrick the Actiontec GT724WGR with this method. It's the method I used to debricked my router (with a lot of help from the FAQ and MTD_CALC). It's running Routertech 2.96 firmware with everything working, except the LEDs.

Actiontec GT724WGR/GT724WG hardware detail:
Main SoC chip: TI TNETD7200 (AR7WRD)
Wireless chip: TI TNETW1350A
Switch chip: Marvell 88E6060

Specific firmware file for Routertech 2.96
Select an AR7WRD PSPBOOT TNETW1350A 4 PORT firmware.
Latest: routertech-ar7wrd-1350A-pspboot-firmware-4ports-20110502.zip
File name: RouterTech_3.7.1B_1350A_20110502_2.96_AR7WRD_psbl_firmware.upgrade.img

1) Set your network connection to a static IP address of 192.168.0.99 (or whatever IP address that lets you connect to the router e.g. 192.168.1.3).

2) Power off the router.

3) Push and keep holding down the reset button and power on the router. The power LED should light red for 5 seconds than change to a solid amber. Once the power LED is a solid amber, you can release the reset button. The router is now running only the bootloader until you reboot it.

4) Start a terminal window and navigate to the location of the firmware you want to flash.

5) Connect to the bootloader's FTP server by running "ftp 192.168.0.1" (or whatever IP address you can access the bootloader at). The username and password are both "adam2". If the IP address above doesn't work, try 192.168.1.1 or 192.168.0.99

6)If you manage to connect to the FTP server successfully, then run the following commands exactly as show (the capitals are required):
quote SETENV mtd0,0x900a1000,0x90400000
quote SETENV mtd1,0x90020090,0x900a1000
quote SETENV mtd2,0x90000000,0x90010000
quote SETENV mtd3,0x90010000,0x90020000
quote SETENV mtd4,0x90020000,0x90400000
quote SETENV NVS_TFTP_LOAD,0
quote SETENV no_auto_vlynq,1
quote SETENV vlynq_polarity,high
bi
quote MEDIA FLSH
put RouterTech_3.7.1B_1350A_20110502_2.96_AR7WRD_psbl_firmware.upgrade.img "fw mtd4"
quote REBOOT

NOTE: Lines 1-5 sets the mtd environment variables to the value MTD_CALC calculated for the firmware we are flashing. Lines 6-8 sets up the environment variables to make the wireless work (mainly "vlynq_polarity" set to "high"). Lines 9-12 flashes the firmware into the router and reboot. Your FTP session show look very similar to the output below:

7) If all goes well, the router will be running the Routertech firmware after reboot. The LED profile will be wrong, but it does not harm the hardware. You should be able to access the router's web interface by pointing your browser at "192.168.1.1". Login using the default user "Admin" and default password "Admin".

NOTE: If you can't login, cycle power to the router. If you still can't login, then connect to the router by running "telnet 192.168.1.1". Login using user "root", password "Admin", and run "reset-config.sh".

8) Once you're login to the web interface, configure the router's modem for your ISP. If everything goes well, you'll have internet acesss.

9) Set up your wireless settings. If you can't change the security setting, then the wireless is not working. Check to make sure the environment variables below are set as shown:
NVS_TFTP_LOAD 0
no_auto_vlynq 1
vlynq_polarity high

10) Change your LED profile to "generic2" under the TOOL --> RT configuration menu. It's not the correct LED profile, but it's the only profile in RT 2.96 that gives you a working status indicator of link activity on the WAN side through the DSL LED.


FYI: Your bootloader's FTP server is still at IP address "192.168.0.1" and still with the "adam2" for user and password. In case you need to the bootloader's FTP server again.

Seems, I have bricked my GT724WGR doing an attempt to use RT (I guess I tried to upload a wrong file). Now router boots ADAM2 FTP server, no telnet, no web face, I tried to debrick it using this method, but got no luck, FTP server again and again. I have downloaded a recovery CD from Actiontec site, got a GTRecovery utility from the image, it stops recovery on transferring binary file to flash, look at the attached image.

Is there a way to see the sun again?)

Did I post enough info about my actions and router? What else should I post?

Edit by thechief: you must be careful what you post or link to here. Your link leads to a Russian web site that seems devoted to gaming. I am prepared to give you the benefit of the doubt, and to treat this as an inadvertent error. Take this as a warning.

Yeah, that Russian site was devoted to image sharing. This is a picture from a well known site) If you find it useful, please, copy this link to the previous post.

The picture simply shows that the attempt to upload the firmware image failed. It doesn't tell us much else (e.g., why it failed). And I have no idea what precisely you mean by this: " tried to debrick it using this method, but got no luck, FTP server again and again".

Maybe you want to explain, step by step, what you're doing, and the outcome of each step. Also, you might want to check the current contents of your router's environment - this could be very informative (try using the RRT or PCTool to read the environment).

[mitrich]

1) I had an Actiontec GT724WGR with firmware 3.0.4.0.11 working. Recently I upgraded firmware to 3.0.4.0.14 taken here;
2) Once I decided to try RT firmware and found this thread;
3) I followed the steps in the post of Mr everdaze but occasionaly flashed wrong file;
4) Since that my router boots with power LED lighting a solid amber. The bootloader starts FTP server, I can do "ftp 192.168.0.1" with adam2/adam2 as user/pass;
5) Tried to flash correct file taken here, got the same as in section (4)
6) Tried to run recovery program taken from the CD image on the Actiontec page, the recovery procedure stops at transferring binary file to flash (file flash ram_zimage_pad.ar7wrd.nsp.squashfs.bin) as shown at the screenshot in my previous post.

Here are mtds for my router calculated by RRT:

mtd0 0x900a1000,0x90400000
mtd1 0x90020090,0x900a1000
mtd2 0x90000000,0x90010000
mtd3 0x90010000,0x90020000
mtd4 0x90020000,0x90400000

What else I should know?

[thechief]

You are still flashing the wrong file (#5). Why do you think that is the correct file? The router is a 1350A wireless router, and what you need is a 1350A wireless firmware. The instructions and RUC report are very clear, but you are still not following them.

Yeah. Debricking successful.
