FLASH FROM FACTORY FIRMWARE
EASIEST WAY TO REFLASH STRAIGHT OUT OF BOX:
1) Download the OpenWrt factory firmware and rename "openwrt-ar71xx-generic-tl-wdr3500-v1-squashfs-factory.bin" to "wdr3500v1_tp_recovery.bin"
2) Plug the router directly into your ethernet and turn the router on. (You may have to turn off wifi (easy) or change the order of devices your computer connects to network (google it) so the ethernet device takes precedence.
3) Open Browser and navigate to 192.168.0.1
4) On the left, navigate to SYSTEM TOOLS
5) Click on FIRMWARE UPGRADE
6) Point the router to the file "wdr3500v1_tp_recovery.bin" you renamed in step 1.
7) Click UPGRADE…..that's it.
8) DO NOT UNPLUG OR POWER OFF YOUR ROUTER DURING UPGRADE or you will likely have a Brick
Thanks to the inspiration from http://www.theoutpost.org/6-techy/tp-link-wdr3600-recovery-without-serial/ who made me brave enough to try it.
With the TL-WDR3500 router, there is a catch: the stock firmware is obtained from the OEM: http://www.tplink.com/en/support/download/?model=TL-WDR3500
An example of an image file with the word "boot" in it is
Cut the first 0x20200 (that is 131,584 = 257*512) Bytes from original firmware:
dd if=orig.bin of=tplink.bin skip=257 bs=512
You should transfer the firmeware image to the /tmp folder and revert back to original firmware (if availlable you can flash the firmware via the webinterface as well):
Via the safer method using sysupgrade:
Or you use the mtd method:
mtd -r write /tmp/tplink.bin firmware
OEM TP-Link firmware for the TL-WDR3500 with the boot part removed to revert to the original OEM firmware:
For general failsafe help, consult the OpenWrt Failsafe Mode page.
For this specific TP-Link model there is an alternative way of flashing the firmware to the router. Thanks to http://goo.gl/Gp0QoR for finding this.
EDIT— THE GUIDE BELOW IS FOR DIFFERENT HARDWARE, THE 3600, not the 3500.
This method may work if you have a brick already, but see above for an alternative method using the factory firmware upgrade function.
This guide assumes you are using Ubuntu.
1. Change your ip address to 192.168.0.66
2. Connect your cable to one of the LAN ports on the router (WAN port won't work for this)
3. Setup a tftp server on your machine by entering "sudo apt-get install xinetd tftpd tftp"
4. Download the OpenWrt factory firmware and rename "openwrt-ar71xx-generic-tl-wdr3500-v1-squashfs-factory.bin" to "wdr3500v1_tp_recovery.bin"
5. Put the renamed firmware in your tftp folder (/var/lib/tftpboot/)
6. Start the tftp server with "tftp 192.168.0.66"
7. Hold down the WPS/Reset button on the router
8. Power on the router. The router will show the two arrow symbol when done correctly.
9. After approximately 7 seconds release the reset button
10. The router will now download the firmware from your server and upgrade
11. After about a minute the router will indicate a restart.
12. Change your IP to 192.168.1.2 and try to connect to Openwrt by telnet.
