-==== Info ====+The latest firmware available is the release build [[https://​downloads.openwrt.org/​barrier_breaker/​14.07/​ar71xx/​generic/​|Barrier Breaker]], with working ethernet and dual-band wireless (disabled by default), and webUI.  
 + 
 +If your wireless cannot be enabled when using wide channel modes, this may be due to the friendly neighbor "​feature"​ that prohibits operation of such a mode and you may have to use the standard modes before wireless can be enabled. For some people radio0 works only when radio2 is also enabled. ​  
 + 
 +Note that in 14.07 VLAN related [[#​switch.ports.for.vlans|switch driver bug]] still not fixed? ​ Fix has been included in trunk since r42653.

 +===== TFTP auto recovery in revision 1.5 ===== 
 + 
 +At least some revision 1.5 routers contains bootloader recovery TFTP client. To activate it press and hold WPS/Reset Button during powering on until WPS LED turns on. Connect computer to LAN1. Using TCPdump, you should see ARP requests from router having address 192.168.0.86 looking for address 192.168.0.66. 
 +  
 +<​code>#​ tcpdump -ni eth0 arp 
 +ARP, Request who-has 192.168.0.66 tell 192.168.0.86,​ length 46</​code>​ 
 + 
 +Set up your computer to address 192.168.0.66,​ netmask /24 (255.255.255.0). 
 + 
 +<​code>​ 
 +# ip addr add dev eth0 192.168.0.66/​24 
 +</​code>​ 
 + 
 +Using TCPdump, you should now see request for new firmware image: 
 + 
 +<​code>​ 
 +# tcpdump -npi eth0 udp 
 +IP 192.168.0.86.2195 > 192.168.0.66.69: ​ 44 RRQ "​wdr3600v1_tp_recovery.bin"​ octet timeout 5 
 +</​code>​ 
 + 
 +Rename factory image to given name and put it into TFTP server root.  
 +-> [[doc:​howto:​generic.flashing.tftp]] 
 + 
 +:!: In case you are flashing back original firmware, make sure original firmware image name does not contain word ''​**boot**''​ -> [[#​back.to.stock.firmware]]. 
 + 
 +<​code>#​ cp openwrt-ar71xx-generic-tl-wdr3600-v1-squashfs-factory.bin wdr3600v1_tp_recovery.bin 
 +# atftpd --no-fork --daemon .</​code>​ 
 + 
 +After downloading,​ the flashing starts immediatelly. After cca. 1 minute, the router reboots automatically. 
 + 
 +=====Back to stock firmware===== 
 +-> [[doc:​howto:​generic.uninstall]] 
 + 
 +{{page>​meta:​infobox:​dangerous&​noheader&​nofooter&​noeditbtn}} 
 + 
 +With the TL-WR3600 router, there is a catch: the stock firmware is obtained from the OEM: http://​www.tplink.com/​en/​support/​download/?​model=TL-WDR3600 
 + 
 +  * in case the file name of this firmware file does not contain the word **//"​boot"//​** in it, you can simply revert back to original firmware 
 +  * in case the file name of this firmware file does contain the word **//"​boot"//​** in it, you need to cut off parts of the image file //before// flashing it: 
 + 
 + 
 +An example of an image file with the word "​boot"​ in it is ''​wdr3600v1_en_3_13_34_up_boot(130909).bin''​. 
 + 
 +Cut the first 0x20200 (that is 131,584 = 257*512) Bytes from original firmware: 
 +<​code>​ 
 +dd if=orig.bin of=tplink.bin skip=257 bs=512 
 +</​code>​ 
 + 
 +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:​ 
 +<​code>​ 
 +sysupgrade /​tmp/​tplink.bin 
 +</​code>​ 
 + 
 +Or alternatively you can use the mtd method: 
 +<​code>​ 
 +mtd -r write /​tmp/​tplink.bin firmware 
 +</​code>​ 
 +

 +==== Useful Information about Stock Firmware ==== 
 + 
 +Updated versions of stock firmware have [[https://​forum.openwrt.org/​viewtopic.php?​id=46371|Firmware Recovery Mode]]. Recommend upgrading latest stock firmware before flashing to OpenWrt for the first time so you can utilise this if necessary.

 +==== U-Boot 1.1.4 modification for routers ==== 
 +Forum member [[https://​forum.openwrt.org/​profile.php?​id=72549|pepe2k]] made a modification of **U-Boot 1.1.4** for **Qualcomm Atheros** SoCs based devices (the project is still being developed, so new devices and SoCs will be supported in the future). Up to date information,​ binary images and sources can be found on official [[https://​github.com/​pepe2k/​u-boot_mod|GitHub repository]]. 
 + 
 +This modification started from [[http://​code.google.com/​p/​wr703n-uboot-with-web-failsafe/​|wr703n-uboot-with-web-failsafe]] project, but supports more devices, all modern web browsers, has a lot of improvements and other modifications (like U-Boot NetConsole, custom commands, overclocking possibilities etc.).

 +===== Hardware Modifications ===== 
 + 
 + 
 +==== USB Modification ==== 
 + 
 +The task was to make ext-root without using the default ports. 
 + 
 +It turns out that the GL850G chipset used by the TP-Link in WDR3600/​4300/​4900 models can handle up to four ports. 
 + 
 +{{:​media:​gl850g.png|}} 
 + 
 +Analysing the router'​s PCB it appears that pins 8(D-), 9(D+), 11(D-) and 12(D+) are unused. ​  
 +Aditionaly each factory USB port has separate power section. 
 + 
 +GND is at the TP7 pin point. +5 V was taken directly from the MOSFET.
