First I flashed with the factory-to-ddwrt.bin file using the web interface (I had to modify the header first as was getting 18005 error message).
Then I flashed with the tl-wr841nd-webflash.bin file again through the web interface.
After playing around with the setup I wanted to flash back to the original firmware.
So I used these instructions

For those who may want to go back to TP-Link on WR841 v8 without webrevert file, here is the solution (I've just tested it succesfully on my own WR841n V8 ):
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 was greeted with a message

Erasing mtd failed: linux
I then found this thread after I had the error message
I have tried to upload a new flash via tftp but with no success, it seems I am not connected to the device OK, no firewalls are turned on.
I set static IP address on PC LAN adapter as 192.168.1.100, 255.255.255.0.
Plugged straight ethernet cable from PC LAN adapter to the ethernet port on the WA801ND.
Ive done these procedures from Windows 7 64bit and Windows XP 32bit.
Output below.......

Well, would this file stil be at this location?
The directory structure on the WA801ND was a little different, it was /tmp/root rather than just /tmp.
What commands can I give to see if this file is still there ?
Well, from the lack of any sort of response from the community and the tens of hours I have invested in learning.
It seems that the only way I am going to be able to unbrick the AP is by doing a hot BIOS flash.
I have chopped up an old notebook motherboard which contains the pads I require to use as the 'base' for the BIOS chip to sit on.
I already have another boxed WA801ND that I can remove the BIOS chip, connect it to my BIOS chip 'base', boot, remove BIOS chip, attach bricked BIOS chip, then hot flash via the web interface.

Last night i bricked my wa801nd when trying to revert from dd-wrt to factory firmware. I tried for about 5 hours to flash the firmware but i was unable to ping the router, i did everything as suggested in multiple forums but i have no luck. So I decided to buy the usb to ttl cable to flash it later.
This morning i downloaded this program "tftpd32.452", i decompressed it and put the stock firmware into the folder, i set the lan adapters ip to 192.168.0.66 and then i did this:
The wa801nd must be power off, then power on until all lights blinking the push the reset button for 5 seconds, only power led and the secure led indicator will be on for a couple seconds. The program will detect your router at ip 192.168.0.86 and a port (may vary) and will start uploading the firmware after that the wa801nd will reboot and it will be alive!!! And i only expend like 5 minutes. Sometimes you just need to relax a lil bit and try again later, lol.
NOTE: It's important to see the program, sometimes it changes the "server interfaces" to "software loopback". If it does, check the log viewer. I realized that my firmware's name was wrong, but the log showed the specified filename requested by the wa801nd, just rename to the right one and restart the process. You will be able to program with out usb to ttl cable.
NOTE 2: My devices bricked after following the ssh method to revert to stock.
I could brick my device again in science porpuses to make a video of the process!

i triny to revert from dd-wrt to factory firmware using the winscp to copy image of dd-wrt to factory firmware in temp
and then using putty to recovr using this command(mtd -r linux -r write/tmp/wa801nd-v1.bin linux)
but when he finish the led of power and system in AP is flashing without stable , led for lan off
