OK, Its been several weeks, My replacement is up and running and they have not requested the bad router back so I guess I own it. Lexridge has provided me files that may be missing in mine. How would I go about installing them ? Currently I have it back to factory firmware.

If cat /proc/mtd shows "art" on mtd8 you should first create a backup on the busybox shell with
dd if=/dev/mtd8 of=/tmp/mtd8.bin
Transfer bin file to your pc, the size should be the same as the art mtd8 you want to flash
You should do same with other mtd flash partitions you want to save.
use WinSCP to copy the new mtd8.bin to /tmp in the faulty units tmp
then do mtd -f write /tmp/mtd8.bin mtd8
wait some minutes that flashing is finished before rebooting

I hope there is no typo in the steps, the owners of this hardware should be able to verify if I'm not wrong before you proceed

Glad to hear it, enjoy it while life as you know it grabs hold for dear while being held together by spit hopes and wishes. Don't ask what that was about just wait a while and it will make sense.

Till then enjoy.

This is how far I got but I don`t know how to proceed from here.

reboot?

You also used dd instead of the command given, tbh when it comes to these things use what is known to work, dd should but meh...

I was just sitting there waiting for something to happen. Don`t know what was backed up or where. I am totally new to rewriting files like this. I haven`t done anything with the file Lexridge provided yet. I need someone to walk me thru this my 1st time. I`m so close, don`t want to bork it up now.

If this is from the good router, then you have to scp the file to your PC using WinSCP (Windows) or via command line (Linux / MacOS / *BSD). Then you can transfer it to the bad router and write it as @servicetech suggested earlier. This will require that dropbear sshd is enabled on the router(s), since you *cannot* use telnet. You will use your user/pass in WinSCP to log in via LAN ethernet, switch remote directory to /tmp, then download the file from there (right click and select download or F5, if memory serves). Then you can transfer it to the other router using similar method...

No, This output is from the bad router. Lexridge has provided me the good file from his good router of the same version. I haven`t done anything with that yet.

Then you're supposed to save it / transfer it via WinSCP as a backup, just in case that isn't the issue, I presume. Transfer it and rename it to mtd8_original.bin. Then you can transfer the good file to the "broken" router and write it to the applicable partition as @servicetech suggested.

I downloaded WinSCP and am able to gain full access to the bad router. I don`t know which directory to look in or copy. I have browsed Dev, Proc and more and find files marked as "8" but nothing marked as "art" but then I really don`t know what I`m doing. I got this far but need more advice.

I think @servicetech wanted you to compare the sizes of the mtd8 partition after DD'ing from your ROM, with the size of the partition file I sent you. They should be the same.

Just focus on the /tmp directory. Just keep in mind that it does't survive a reboot.

/tmp is stored in RAM so yes, reboot and kiss it bye bye.

@ramblin, you have the full set of instructions already from servicetech, he already described it, so there is no mystery to uncover.

What I would add and what Ive said now multiple times is, before you flash ANYTHING you should backup EVERYTHING, ALL partitions/Uboot/CFE whatever BACKUP BACKUP EVERYTHING, and confirm backups are good. Then and ONLY then get into flashing, any thing goes wrong, you at least have backups that will allow you to recover anything that was done by mistake or shit happened.

Back again with more issues. All efforts to download the file have failed. Things I have tried are, download the MTD8 file, download the MTD folder, download the Dev folder to many different locations on my computer. All fail with this message. Are there other ways to SCP the file ?

This is also misspelled /dev/mtd8
But it is questionable if you can copy the device file just like that.

The instruction was actually to copy the contents of the partition to /tmp/mtd8.bin
and then copy the file /tmp/mtd8.bin on the PC
