 +''​Note:''​ be extremely careful when soldering a serial console on TP-Link TL-WDR4900 - the design of the PCB is not well suited for soldering and important paths/​connections are near the soldering points. We have now 3 Routers which are dead, just because we used too much solder... 
 + 
 +===== Installation ===== 
 + 
 +OpenWRT may be installed [[doc/​howto/​generic.flashing#​method.1via.oem.firmware|via OEM firmware]] on both versions. 
 + 
 +v1: [[http://​downloads.openwrt.org/​barrier_breaker/​14.07/​mpc85xx/​generic/​openwrt-mpc85xx-generic-tl-wdr4900-v1-squashfs-factory.bin|openwrt-mpc85xx-generic-tl-wdr4900-v1-squashfs-factory.bin ]]

 +  * If you do not speak chinese and are not familiar with the standard TP-Link firmware, please see the screen shots below for help.

You may also wish to install the web user interface [[doc/​howto/​luci.essentials|LuCI]],​ after which you can manage your router at http://​192.168.1.1

 +==== VLAN ==== 
 +To get tagged and untagged traffic working on the same port a patch for the switch driver is needed. Refer to: https://​dev.openwrt.org/​ticket/​12181#​comment:​73 
 + 
 +===== De-brick or OEM installation ===== 
 + 
 +==== Using TFTP + Serial method ==== 
 + 
 +=== Pre-requisites === 
 + 
 +  * a serial connection (e.g. TTL, RS232) from your machine to the router. 
 +  * a terminal program (e.g. minicom, screen) set for 115200 Baud, 8 data bits, no parity, 1 stop bit, no flow control. 
 +    * It is **strongly recommended** not to connect the 3.3V (or any) voltage line - use the router'​s own power supply instead. 
 +  * a __factory__ OpenWrt firmware image into your TFTP server folder (see [[#​installation|Installation]] above) 
 +  * a wired ethernet connection from your computer to one of the router'​s LAN ports. 
 +    * IP address on this connection should be statically set to 192.168.1.x/​24. 
 +  * a TFTP server started on your local machine 
 +    * must be listening on the same link/IP address as the wired ethernet connection to the router 
 +    * v1.x models prefer the server address 192.168.0.66,​ v2.0 prefers 192.168.1.100 
 + 
 +=== v1.x Flash Write Procedure === 
 + 
 +**<color red>This section applies to v1.x only!</​color>​** ([[#​v2.0.flash.write.procedure|version 2.0 method]]) 
 +  - Router should be unplugged (power off), your serial line connected, terminal open and TFTP server installed not yet running. 
 +  - Copy your desired openwrt image for the TPlink-WDR4900 into your TFTP server folder and rename it into ''​openwrt.bin''​ (to save some typing within the flash procedure). 
 +  - First goal is to get the command prompt from the U-Boot bootloader on your router. 
 +  - Plug in your router and be ready to type "''​vl''"​ just after you see the line ''​Autobooting in 1 seconds''​ (Spamming "''​vl''"​ around this point helps):

 + 
 +**<color red>This section applies to v2.0 only!</​color>​** ([[#​v1.x.flash.write.procedure|version 1.x method]]) 
 +  - Be sure the router is powered off (there'​s a handy power switch beside the power line). 
 +  - Connect your serial and ethernet cables to your computer. 
 +  - Open your terminal for the serial connection. 
 +  - Power on the router 
 +  - When you see ''​Autobooting in 1 seconds'',​ quickly type "''​tpl''"​ to access the command line. 
 +    * there is no harm at all typing "''​tpl''"​ repeatedly from the moment you power on, I often start when I see the U-Boot bootloader header. ;-) 
 +  - Start the TFTP server running on your computer. 
 +  - At the ''​ap135>''​ prompt, type the following commands: 
 +    - ''​tftpboot 0x81000000 openwrt.bin''​ (where openwrt.bin is the name of your firmware image) 
 +    - ''​erase 0x9f020000 +0x7c0000''​ 
 +    - ''​cp.b 0x81000000 0x9f020000 0x7c0000''​ 
 +    - ''​bootm 0x9f020000''​ 
 +  - Congratulations! 
 + 
 +==== Reset Button Method (no serial cable needed) ==== 
 + 
 +If you want to de-brick/​upgrade your router using TFTP without a serial cable follow these steps: 
 + 
 +=== Pre-requisites === 
 + 
 +  * Copy a working & full OpenWrt sysupgrade image into your TFTP server folder (e.g: https://​downloads.openwrt.org/​barrier_breaker/​14.07/​mpc85xx/​generic/​openwrt-mpc85xx-generic-tl-wdr4900-v1-squashfs-sysupgrade.bin) so it will be found under the path /​wdr4900v1_tp_recovery.bin You can also use the image used for reverting to stock firmware if you prefer to do so, but it has to be placed under the same path. 
 +  * A TFTP server started on your local machine on LAN address 192.168.0.66/​24. 
 +  * Connect your LAN-port to one of the routers LAN  
 + 
 +=== Procedure === 
 + 
 +  - Router should be unplugged (power off) and TFTP server installed not yet running. 
 +  - Copy your desired openwrt image for the TPlink-WDR4900 into your TFTP server folder and rename it into ''​wdr4900v1_tp_recovery.bin''​ (as the router will search for this file). 
 +  - Make sure your card has address 192.168.0.66. 
 +  - Start the tftp server and make sure it is listening on 192.168.0.66  
 +  - Plug in your router and keep the WPS/Reset button pressed until the tftp server confirms the transfer is done 
 +  - Wait for the router to reboot, the new image will then be loaded 
 +  - A pack ready for doing this, containing TFTPD32 server and the latest TP-Link firmware, can be found here: https://​forum.openwrt.org/​viewtopic.php?​pid=236428#​p236428 
 +  - Also there'​s a video of the process: http://​www.youtube.com/​watch?​v=54PAS0gvW2k 
 +===== Failsafe / reset ===== 
 +After all else failed, I found [[http://​www.binaryfriend.ru/​2012/​10/​how-to-hard-reset-openwrt-on-tp-link-1043nd]]. ​ Extremely simple. ​ Please see the original page for more info.  Summary: 
 + 
 +  - Power the router up; 
 +  - After powering up track the SYS light when it starts to blink, when it does press and hold the QSS button till SYS lights starts to blink faster – router goes to recovery mode; 
 +  - Telnet to the router on 192.168.1.1 – no password needed (if your computer doesn’t gets IP address from DHCP assign it manually for i.e. 192.168.1.200 with netmask of 255.255.255.0);​ 
 +  - In telnet terminal type `mtd -r erase rootfs_data` to reset OpenWRT to it’s defaults. 
 + 
 +===== Reverting to stock firmware ===== 
 + 
 +You can revert to stock firmware by following these steps: 
 + 
 +  * Download / copy with SCP this firmware to the /tmp folder of the router: [[https://​www.dropbox.com/​sh/​g8dyafqrato12pc/​AADtSjx_MVot7asdqeRtvVVza?​dl=0]] 
 +  * Optionally check MD5 hash: 1148EFD09C6D9B07E6A01259A4EBEF72 
 +  * Rename to firmware.bin (less chance for spelling errors and unsupported characters) 
 +  * Open a SSH session to the router, cd to /tmp 
 +  * Execute the following command: mtd -r firmware.bin firmware 
 +  * Wait until the router reboots 
 + 
 +Note: You can only flash this firmware version because it has no BOOT in the filename. This image and OpenWRT images are the exact same size. Other images from TP-Link do have BOOT in the filename and these files are also  
 +more bytes than this one.
