Hi Guys,
I re-tired flashing DD-WRT July 23, 2014 firmware and checked back that my WAN won't work.
Now I'm trying to get back to TP-Link original firmware by using the WebRevert file from the sticky section but I'm getting Upgrade Failed from DD-WRT and even if it says Upgrade Successful DD-WRT is loaded and not the TP-Link one. Pressed the Hard Reset button for about 30seconds but still the same. It ain't even accepting older DD-WRT firmwares(web flash files).
I've tried this before n it worked well but this time it ain't working...
Can't use the router coz of this state now..
Can anyone help me out on what can be done..
Hoping for something that can get it back.. _________________ TP-Link: TL-WR740N

this is not an easy one and some have bricked rheir router
1. You will have to flash via WinScp and before enable the ssh daemon (service)? If not, SSH administration will be greyed out and disabled. You need to enable both the service and the administration.
2. Upload the web revert (dd-wrt to stock)file using Winscp in the /tmp folder of your router.
3. Connect with Putty and give this commands:
cd /tmp
mtd -r write xxx.bin linux

write tl-wr841nv3_webrevert.bin linux, LOM corrected one of my posting Webrevert is only ment to be use with WEB-UI, and this poster says it worked 100 % here you can download a stripped FW for 740 ftp://tplink-forum.pl/orgin_bez_boot/
Every command at once hitting Enter.
Wait for the flashing to complete then restart and reset to factory defaults.
it is not the last version just upgrade normally after flashing this one

Woo..!! Thankfully I didn't need to do the SCP method...
I had completely plugged out my Router for long and after I connected tried the webrevert via GUI and in the first attempt itself it happened...
Great..
Thanks for the help anyways.. May be helpful some other time _________________ TP-Link: TL-WR740N
5 On WinSCP:
5.1 Select New Site;
5.2 File protocol: SCP;
5.3 Hostname: 192.168.1.1 (or your router IP);
5.4 Username: root
5.5 Password: your admin pass
5.6 Drag downloaded firmware from Download folder and drop in /tmp
5.7 (Important, I think...) On Transfer Settings, select Binary
5.8 Transfer;
6 On putty;
6.1 Login on 192.168.1.1 (user root and pass);
6.2 Type:
cd /tmp (Enter)
mtd -r write xxxxx.bin linux (Enter) (Sure, replace xxxx with your firmware filename...)
7 It worked for me in a tp-link wr740n v4.22;
8 Use at your own risk. (I cannot confirm if it will work on your model, router, etc.)
9 Sorry for my poor english;
