See peacock thread (link HERE), specifically the first two paragraphs of note #1 might be worth a peek.

Just for grins, i'd read all the notes listed in BOLD at the top Smile

Hello everyone,

3-dd-wrt-25628-ea2700.trx

All this was done using xubuntu 14.04 and tftp 0.17-18ubuntu2

TFTP commands:
tftp> connect 192.168.11.1

tftp> trace
tftp> rexmt 1
tftp> timeout 60
**when router returns pings:

Any help or comments would be much appreciated.


The TFTP protocol used for CFE seems not implemented with standard linux tftp command. Indeed, with a wireshark I've seen that the admin password is sent in addition of each TFTP frame.

So, the only "tftp" tool that works that I've found is the Tftp.exe from windows I've found somewhere in linksys forum.

thank you both very much for helping.

I grabbed a laptop with win7 and did the following:

assigned static ip 192.168.1.5/24
gateway 192.168.1.1
dns1 192.168.1.1
disabled wifi
no AV running
disabled FW


started the TFTP.exe app and inputed:
Server: 192.168.1.1
password: <blank>
file: FW_EA2700_1.0.14.129982.SSA

started a ping 192.168.1.1 -t
plugged router ( while talking to it nicely in case it helped..)
started the upgrade process as soon as pings with TTL=100 started showing up.
Once the flash process finished the router rebooted
ping replies with TTL=100 for about 30 secs.
ping go dead.
I wait 15 minutes, nothing happens.
I unplug and replug the router.
pings replies with TTL=100 for about 30 secs.
pings go dead.
wait 15 mins just in case.
nothing...
unplug router.

I try everything from stratch, this time with FW_EA2700_1.1.40.162751_prod.SSA.
After flash finishes, router reboots..

**** The following lines repeat over 4 times.
pings replies with TTL=100 for about 30 secs
Router reboots again...
pings replies with TTL=100 for about 30 secs
****
router reboots.
pings replies with TTL=100 for about 30 secs
pings go dead.
I wait 15 mins just in case.
unplug router, wait 5 seconds replug router.
ping replies TTL=100 for about 30 secs
ping goes dead.
unplug router

I'm guessing its useless to use the HTML flash from _Robb_ since there are no replies with TTL=64?

Peacock thread states that EA routers should not be 30/30/30 hard reset yet it is mentioned
many times on this thread that ppl had to perform this step. --- confused.

I also read all pages of this thread: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=47536&postdays=0&postorder=asc&start=60

I also did everything with TFTP2.exe, same results.

If I understood correctly you upload firmware with TFTP.exe conducted correctly and the program reported you success upload, router reboot but firmware don't work and router cannot be accessed.
I also have this problem sometimes, then help only upload firmware via serial adapter.
See here: http://www.dd-wrt.com/wiki/index.php/Serial_Recovery
Exact pin connection here: http://www.dd-wrt.com/phpBB2/viewtopic.php?p=936446#936446

Edit:
I forgot the topic I have open some time ago: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=276785
Make step by step according to instructions on Serial Recovery page.

@robo77: For serial, you can see my magical command here:
http://www.dd-wrt.com/phpBB2/viewtopic.php?p=938990#938990

@JP_mud0: I haven't left blank password but I've set admin password (by default "admin" after a hard reset).

Hi guys, I just wanted to see if anyone knew when an installation guide would be available. Most of the verbiage in this thread goes over my head, but I saw the wiki guides, and they seemed manageable.

I thought I had done my homework when buying this router, trying to find if it supported a feature I now know is called QoS, and while I thought the default software kind of does, it's not as deep as I would like. So I found dd-wrt, and it sounds great, but most of the discussion so far has been way out of my scope of understanding about computers.

I'm not asking for hand holding, just a more concise guide.

@Fuli10, thanks for your comment. I'll give it a try with the password set to "admin".

@robo77, thank you very much for sharing your experience. I'm currently searching for the parts needed to do the serial connector. The Nokia CA-42 isn't showing up at a good price so I'm considering going with http://www.amazon.com/niceeshop-PL2303HX-RS232-Module-Converter/dp/B00F167PWE/ref=cm_cr_pr_product_top

Thanks again for all the input.

I bought one like this, actually 2. They work fine. It ships from Hong Kong so it takes about a month to get to North America. I had one burn out on me, so I was glad I bought a double pack.

I tested your command but it does not work.

My standard procedure to flash:
nvram erase
flash -noheader : flash1.trx
go


This works well but only with cisco firmware, load DD-WRT I get this mesage:
Reading :: Failed.: I/O error
*** command status = -4


flash -noheader 192.168.1.2:dd-wrt-26332-ea2700.trx flash1.trx (tested 192.168.1.1 router IP, 192.168.1.2 tftp IP, builds 25974 and latest 26332)
This command don't load firmware get this message:
Reading 192.168.1.2:dd-wrt-26332-ea2700.trx: Failed.: Timeout occured
*** command status = -21

Please note that CFE commands are using standard tftp protocol (without the added password). So Tftp.exe should not work.
Have you try by yourself to load the binary from the server ?

Code:

user $ tftp
tftp> connect 192.168.1.100
tftp> get FW_EA2700_1.0.14.129982.SSA
Received 13057672 bytes in 0.4 seconds
tftp> quit

I have tested command with Tftp.exe (now i know this don't work), but I also have tested the alternative TFTP server (don't know if I set anything wrong or program is a crap but its have never worked properly).

Now I tried it again with another TFTP server ( https://sourceforge.net/projects/tftputil ), this work fine and your command now works.

Thank you, you saved me a lot of time with this command.

@all: tested latest build 26348 still not work, and soft-brick router.

Don't update to version (26XXX) this not work with router, maybe softbrick it.

You are correct, do not flash that 26x builds until mods, or devs have confirmed working... There was recent changes to svn that fixed this issue, but with the new drivers was soft bricking a lot of devices.
