iDirect 5350 Bricked

Hello Everyone,

I am having an issue with a 5350 iDirect modem. The modem has been bricked and has entered the classic recovery state "Can't reload stack."

Typically I would halt the RedBoot process by pressing the space bar at start-up but it doesn't exactly start up like a typical modem.

Here is its out-put in HyperTerminal as soon as power is applied:
Speed: 9600
Data Bits: 8
Stop Bits: 1
Parity: None
Flow Control: None

Begin modem out-put:

A full boot out-put list is attached to this post.
I have tried multiple baud rates, different COM adapters, WinSCP, Putty, HyperTerminal, etc. with no luck.
As you can see, it's only when it first starts that it has the odd symbols.

Any suggestions?

I think I have seen this before but cannot remember what steps I performed to unbrick the modem.

Usually I would do as you suggested and stop loading Linux at the redboot.

Perform the following steps to recover the root password for the iNFINITI
1. Connect a PC to the modem via the console port. You can use Hyper
Terminal or Tera-Term for this operation.
2. Reboot the iNFINITI NetModem.
The message DRAM Test Successful displays.
3. Press the Spacebar 3 - 4 times.
The Redboot> prompt displays.
4. Type: fis load Linux
The Redboot> prompt re-displays.
5. Type: exec -c ďroot=/dev/mtdblock2 console=ttyS1,9600
The /# prompt displays. This indicates that you logged in without a
6. Enter the command: passwd
You are then prompted to enter a new password.
7. Enter a new password.
8. When prompted, type the new password again to confirm.
9. Once you are successfully logged in, reset the iNFINITI remote. You can now
log into the iNFINITI remote.

Then also confirm that you can gain IP access to the modem.

1.† The easiest way to determine the NetModemís IP address is to establish a
console session and type the appropriate console command
2.† Open a console session to the 0NetModem. (See Appendix A for details.)
Note: Use the† ifconfig command to find out the currently-configured IP
3.† At the Linux prompt, type the following command: (for 3000 series, type:
ifconfig iXP0 )
ifconfig iXP1
4.† Check the IP address and subnet mask of the Satellite Router.
5.† Configure your laptopís IP address to be in the same subnet as the Satellite
Routerís interface.
6.† Use the following commands to change the default gateway of the Satellite
Router to be the same as your laptopís IP address by entering the following
route Ėn
route del default gw
route add default gw

Once you can ping the modem you should then be able to reapply all the image packages using iSite. Then apply an options file with correct SN.

I've tried to halt the boot process but it ignores the space bar interrupt. As you can see at the beginning of the modem's start-up, the characters are not typical to a standard modem's boot. The prompt to interrupt Red Boot on a regular modem comes at the same time the strange characters on my modem appear, and like I've said, pressing the space bar does not stop the boot. It is all very strange.

I've tried various settings for the communications port such as baud rate, but I cannot get the modem to display normal characters when power is first applied. It will only display normal characters after the first few lines.

I have conducted the procedure for reloading modem images and options files via command line before, but thank you for the input fluffymassive.
