 +==== 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):

 + 
 +In case you failed the right timing just reboot again until the prompt appears 
 +<code>=></code> 
 + 
 +  - (//optional//) Now lets check what kind of parameters the u-boot loader expects (e.g file name of firmware, IP via TFTP & load address). 
 +  Type ''tftpboot'' & press ENTER … 
 +<code> 
 +=> tftpboot 
 +Check for phy link status

 +Load address: 0x1000000 
 +Loading: T T T T T T T T T T  
 +Retry count exceeded; starting again 
 +</code> 
 + 
 +  - As you can see, uboot expects a firmware image file name "''uImage''" at TFTP server address ''192.168.1.104'', 
 +  then, just change you local ip into ''192.168.1.104'' and start your TFTP server. 
 +  - Start the uBoot's TFTP client to download the image from your local machine by typing: ''tftpboot 0x1000000 openwrt.bin'' + ENTER 
 + 
 +<code>

 + 
 +  - The last line needs to show a size of f80000 hex, otherwise your image is unsuitable. 
 +  - To select the SPI flash memory type: sf probe 0 
 +<code> 
 +=> sf probe 0 
 +SF: Detected S25FL128S_65k with page size 256, total 16 MiB 
 +16384 KiB S25FL128S_64K at 0:0 is now current device 
 +</code> 
 +  - Now we need to erase parts of the flash memory to be able to copy your fresh loaded firmware into it, 
 +    just type in the prompt ''sf erase 0x60000 0xf80000'': 
 +<code> 
 +=> sf erase 0x60000 0xf80000 
 +SPI flash erase successful 
 +</code> 
 + 
 +  - Now just copy the image to the right place by typing ''sf write 0x1000000 0x60000 0xf80000'' 
 +<code> 
 +=> sf write 0x1000000 0x60000 0xf80000 
 +SPI flash write successful 
 +</code> 
 + 
 +  - So, in case your image is the correct one, you should do just a single reboot to have a working TL-WRD4900 back on your desk. 
 +    Type ''reset'' or just un-plug and re-plug the power of your router and watch the boot process. 
 +<code> 
 +=> reset 
 +</code> 
 + 
 +=== v2.0 Flash Write Procedure === 
 + 
 +**<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: http://downloads.openwrt.org/snapshots/trunk/mpc85xx/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 or wget this firmware to the /tmp folder of the router: [[ftp://everbest.ftpserver.biz/Share/TP-Link/TL-WDR4900%20Firmware/wdr4900nv1_en_3_14_1_up(130304)_beta.bin]] 
 +  * Open a SSH session to the router, cd to /tmp 
 +  * Execute the following command: mtd -r write wdr4900nv1_en_3_14_1_up(130304)_beta.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.
