I am also trying to get DD-WRT on this router, but without much success so far.

Though, given that I got it for a few bucks, I opened it up and identified some IC's. So here some gathered specs:

Model: F5D7230-4
Hardware rev: 4000tt
FCC ID: K7SF5D7230A
Platform & Freq: ?
RAM: 2MB (?? see IC's)
Flash: 8MB
NIC: ?
WLAN std: b/g
mini-PCI: no
Serial Port: ?
JTAG Port: -
Ethernet: 4 LAN/1WAN
Voltage/Input: 4.5V/1.5A


Identified IC's:
1x MX 29LV800BTTC-70 = 8Mb Flash
1x 88E6060-RCJ = MARVELL 6 PORT ETHERNET SWITCH
2x EM636165TS-6 = 1MB SDRAM ??

What I guess is the CPU has a cooling body "glued" on, which does not seem to be removeable without harming the device.

I have attached fotos of the upper and lower side.

Any help would be appreciated.

Regards,
Wimpi

8Mb = 1MB

Needs at least 2MB to run dd-wrt..

Murrkf: This is another version, and it is easy to brick these things (got a 1444 bricked).

soulstace: 8MB = 1MB could you please elaborate?

The datasheet for the flash seems to indicate 8Mb?

8 megabit = 1 megabyte. You need two megabyte to put DD-wrt on. Not sure if you have 2x1MB or not. The link basically said timing is everything....not sure how you could brick a router by using different timing IF you are using the right firmware.

Right. Sorry for bothering.

Just one, as you can see on the photo....no DD-WRT for the 4000tt then :)

The bricked Router was an upgrade from .3 to .4 that went wrong; however, I suspect that after too many flashing cycles and 2 years of constant operation it's not so strange, and I wasn't looking for debrick help but rather info on the 4000tt revision (they are selling them off around here very cheap, but without a better firmware it doesn't really make sense to buy more).

If you have a brick, consider donating it. I think Redhawk0, who has been missing from here for a week or so but is very helpful, is looking for bricks. So are some of the developers.

But, if it only has 1MB on it, it might be useless to everyone.

It`s never a bother to ask questions. You might have saved someone else from bricking their router. Thanks.
