Here is the first line from the /etc/passwd file, containing the hashed root password:

The firmware source I downloaded this evening includes an /etc/passwd file with a different root password hash, so they probably changed it between firmware versions:
Code:
root:$1$$tpzh2zeS3GkeqXlybY18k0:0:0:root:/:/bin/sh

I have bf running on root:$1$$oQoSkI0acntd1i from couple of days and can continue. what will help? stop on old one and start on new hashed? let me know if anything else I can help or test.

I've had JTR running on the $1$$oQoSkI0 password from the 1.0.15 firmware for three days now. It's still working. I suspect the other password in the source tarball is from the older firmware.

Note: Posted to dslreports.com VOIP forum Monday evening.

JP2 is the serial console port, and pins were already installed. Very Happy Starting from the pin near the JP2 silkscreen lettering:

1 - 3.3 VDC
2 - TXD
3 - RXD
4 - GND

115200, 8/N/1

Then began comparing the boot log from the console to the compressed partition header from the Flash RAM. Determined the following positions/values:

00 - 03 Partition header
04 - 07 ??
08 - 11 ??
12 - 15 Compressed image size in bytes
16 - 19 Image load address
20 - 23 Image entry point
24 - 27 ??
28 - 31 ??
32 - 63 Vendor string / Image Name

Check vendor string... Image Name: ADM8668 Linux Kernel(2.4.31)
Created: 2008-04-09 19:03:19 UTC
Image Type: MIPS Linux Kernel Image (gzip compressed)
Data Size: 5627840 Bytes = 5.4 MB (Size = 55DFC0)
Load Address: 00002000
Entry Point: 80220040

To identify:
image creation date/time
image checksum

Are you sure you didn't get some of the WRT54G-TMs (classic black/blue Linksys look)? The WRTU54G-TMs are listed at over $50 each on that site.

Or were you just in the wrong thread? Razz

They've got a WRTU54G going for $9.99 + $7.xx shipping and handling, right now. :D

I think T-Mobile received a LOT of these as returns and they're just ditching them, frankly.

Those units had CFEs, though, not U-boot. I'm not familiar with U-boot and its bootstrap procedure, though, so I'm not qualified to speak about it. I might take a look at the sources when I get a chance. Now I'm interested. Smile

I think this page might be a good introduction for U-boot.

It's wireless-G (non-MIMO), but with 8 meg Flash, 64 meg DRAM, two SIM card slots (USB-connected, I believe) and two RJ-11 UMA ports, it's got plenty of room for DD-WRT Mega. (The ADM8668 Wildpass SoC is MIPS R4000-based) Linksys/T-Mobile currently stores two separate copies of the Linux kernel and SquashFS partitions in the Flash. I guess one of those pairs is either their fall-back/recovery or a scratchpad area for live upgrades. I haven't powered it up or connected yet, but will probably open it up and install a console port soon.

Unless this device is built with two 8M Flash chips, what you said above that the device stores two separate copies of the Linux kernel and SquashFS partitions in the Flash does not make sense since a WRTU54G-TM firmware is bigger than 5M in size. The total of two WRTU54G-TM firmware copies will definitely occupy a bigger space than 10M and that won't fit on an 8MB Flash chip, will it?

I took a look at the source, and it doesn't appear to have a makefile or any build scripts that I can find... this is going to be tougher than I thought.

The second Linux partition is significantly smaller than the first, as is its SquashFS partition. I suspect these are a very minimal configuration used only for loading firmware updates onto the main partition, or possibly for recovery.

Look for a small shell script named easy.sh (or something very similar.) I believe it's the original ADMtek build script that calls two or three other scripts to perform the build. Or that might have only been in the Vinetic sources from Samsung. My memory isn't that good these days. Sad
