I flashed DD-WRT v24-sp2 (06/23/14) std on my W841ND v9 router. I see really bad performance with web interface and I wish to revert back to my firmware. I followed these steps:
1. Download WinSCP and Putty (if you are using Windows machine).
2. Enable SSH and Telnet on DD-wrt.
3. Connect PC with router with LAN cable.
4. Download orig firmware from TP-LINK, extract and change name for more convinient for example: tplink.bin
5. Connect with WinSCP with SCP file protocol to router.
6. Transfer tplink.bin from PC to /tmp directory on router.
7. Close WinSCP, run Putty and connect to router with Telnet type connection.
8. While logged on router type the following command
mtd -r write /tmp/tplink.bin linux
and hit enter.
But I am getting this:
Writing from /tmp/tplink.bin to linux ... [e]Erasing mtd failed: linux
I tried searching the forums, but I am not getting any specific answers for v9. Many posts say v9 is not supported, but I downloaded the firmware for v9 from the official list.
Is there anyway I can revert to my tp-link firmware? I am pretty new to dd-wrt. Any help would be really appreciated.
I seen QUALCOMM in second picture. You need wired connection, no wireless.
I have Qualcomm Atheros Ethernet Controller. I have plugged in to WAN port of router. I just have to setup TFTP server as per screenshots and just connect the router? I dont have to do anything on TFTP window?
Some progress. It starts transfer now, but it throws timeout error mostly at 25% (it reached 44% once). Any idea, how can I work around?
I use default tftp settings. When you power on the router see if the tftp change address to 172.xxx or something else might be. see in pc's adapter speed. It must be 100 or more. try another computer ot tftp if you have
mine is in c//tftp see my settings in attachment. On youtube there is a video about tftp recovery mode. Watch it

I was able to transfer after changing anticipation window, but the router didn't reboot automatically. I waited 10-15 minutes, but nothing happened. The power LED was on and rest of the LEDs were blinking simultaneously. I rebooted manually, but its still the same.
