FYI Netgear WNR1000 uses the Broadcom 5356 SoC, therefore I can't help much with that, since I am extensively working with the 6358 installed in the Westell routeres. Since so far only OpenWRT seems ...

A90-750045-07 is an edition of the 7500 (as opposed to the 7501). The first 4 digits after A90 specify the board model, the two digits after that is the market (ISP) the router is being used/distribu ...

I think the CFE6358 is encrypted or compressed, as I can't see any text visible in the binary. Can't find any source for it either, so adapting it to the flash doesn't seem likely.

Tried compiling ...

Well, tried to move on and replace the CFE, have it run its initialization procedures, then take a "snapshot" of the "NVRAM" area (offset 0x580). Problem is the CFE that hanschan ...

It's been taking me forever to put the stock flash back as it was. Tried to do it in sections (bootloader, kernel, writable FFS filesystem, readonly Squash file system, fix up the boot vector at the ...

Got the original kernel back. Found out the last few bytes at the end of the flash is the vector to the beginning of the header where the kernel resides.
It of course complains that there's no rootf ...

This is getting scary.
First I accidentally wipe the bootloader by forgetting the 0x1e prefix when writing the original kernel back to its original spot.
I get that fixed, but even after I reinstall ...

Looks to me that the Verizon flash layout wastes a lot of space.
The 7501 has 8MB of flash (7500 only has 6)
The bootloader takes up (discounting the 0x1e000000 offset) 0x000000-0x020000 or 131KB.

I had set it up where the whole bin was treated as one upgrade section, but in reality th Westell style upgrade file is two sections: first is the kernel, the 2nd is the readonly root, the 2nd section ...

I was able to generate an App.upg that the web would accept: Using hex editor, removed broadcom bin header from 0x00-0xff. That leaves just the kernel and the new filesystem.
Then use FlashImageBui ...

I am examining the headers in app.up, similar location in flash backup, and openwrt-96358VW2-generic-squashfs-cfe.bin. Perhaps the bin can be patched with the proper header to get the web to install ...

You could probably install the firmware by renaming openwrt-96358VW2-generic-squashfs-cfe.bin to app.upg but do at your own risk, as the bootloader may fail to hook into the new firmware. Note though ...

Hi All,
I have a Westell 7500
Unlike the 7501, the 7500 has an ADSL port and no USB port. Supposedly one of the LAN switchports can be set to a USB A port with a special cable. As someone mentione ...
