That heat sink sucks! Found solder balls stuck under it. Used a staple to pry it off. Watch out though! That solde could pop of and hit your eyeball. It did for me. Dang that hurts.
Ok i'm new to serial flashing, but feel pretty confident I can manage it, any chance you could point me in a direction to get started, or give me step by step directions to follow for serial flashing this router.
- tftp server (I'm using tftpd-hpa under Ubuntu)
- the firmware.bin for this device (NOT the webflash-one)
- terminal program (I'm using minicom)
First set your terminal program to use 57600 8N1 as comms parameters, no flow control. Connect your device via its LAN-ports to your network. Place the firmware.bin in the root of your tftp-server. (The default in Ubuntu is /var/lib/tftpboot).
- On the boot menu you need to select something like "Load system code then write to Flash via TFTP". In my case this is number '2'. (In my case the boot delay seems to be set to near zero, so I start pounding '2' while turning on the device).
Then, we are greeted with:
Code:
2: System Load Linux Kernel then write to Flash via TFTP.
Warning!! Erase Linux in Flash then burn new one. Are you sure?(Y/N)
Hit 'Y'.
We are then asked for the device IP. Make sure it's in the same IP-range as your TFTP-server and it is unused on your network.
Next, the following appears:
Code:
Input server IP (192.168.99.8) ==:
Enter the IP of your TFTP-server.
Next, we're asked for the filename to flash, enter firmware.bin (or whatever you named it, it's the file you put in the tftp root).
If all goes well, you'll see:
Code:
Using Eth0 (10/100-M) device
TFTP from server 192.168.1.249; our IP address is 192.168.1.42
Filename 'firmware.bin'.
TIMEOUT_COUNT=10,Load address: 0x80100000
Loading: Got ARP REPLY, set server/gtwy eth addr (00:10:18:53:9d:6e)
Got it

Thank you! I pretty much figured it would be something simple like that, but wanted to get a clearer idea before I broke out the soldering iron. Just waiting for the ttl to rs232 converter now.
I've got to say just been messing around with the stock firmware for the Senao ESR-9752, it's pretty damn good... probably the best stock firmware I've seen so far, still want to put dd-wrt on these puppies but once again I'm impressed by how much senao delivers for such low prices.

I have experience flashing DD-WRT on quite a few devices but I am having alot of trouble with my engenius esr-7952. It sounds like the device you guys are using has a serial port on the back, and mind does not.
I have a Cisco style cable that goes from ethernet to serial (female) that i've tried, having the serial end plugged into the pc and the ethernet in either the wan or lan ports on the esr-7952 and am getting nothing in the terminal program.

Any Ideas?
You put the serial connection into the LAN/WAN ethernet ports? That ain't gonna work. You have to actually open the damn thing, use a RS232 to TTL converter to get to the console.
GraveR.. Thanks for the quick reply. I figured it worked like a cisco pix.. but i guess i'll have to get my hands dirty and take this thing apart. Thanks again
Hello
I'm sure that I'm more stupid than usual, but I have to ask; how do I open this box?
I've found one screw under the label under the router. There are no screws under the rubber feets.
I've removed the screw under the label, but still can't open the box!

If you have the WL-342, then the only option is to force the box open after removing the single center screw. The other supports seem to be glued to the case.
