 +===== De-brick or OEM installation using the TFTP and RS232 (serial) method =====
 +
 +If you want to de-brick/upgrade your router using TFTP you follow these steps:
 +
 +
 +==== Pre-requisits ====
 +
 +  * Serial RS232 connected from your machine to TL-WDR4900 & a terminal program (e.g. minicom, screen) set to **115200 8N1**, no flow control, 3,3V.
 +  * Copy a working & full OpenWrt firmware image into your TFTP server folder (e.g: openwrt-mpc85xx-generic-tl-wdr4900-v1-squashfs-factory.bin).
 +  * A TFTP server started on your local machine on LAN address 192.168.1.x/24.
 +  * Connect your LAN-port to one of the routers LAN ports.
 +
 +
 +==== Written Flash Procedure ====
 +
 +  - 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'':

 +
 +In case you failed the right timing just reboot again until the prompt appears
 +<code>=></code>
 +
 +  - 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
 +Speed: 1000, full duplex
 +Using eTSEC1 device
 +TFTP from server 192.168.0.104; our IP address is 192.168.0.136

 +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>
 +=> tftpboot 0x1000000 openwrt.bin
 +Check for phy link status
 +Speed: 1000, full duplex
 +Using eTSEC1 device

 +</code>
 +
 +// UNCOMPLETE (needed flash memory address)//
 +
 +  - The last line needs to show a size of f80000 hex, otherwise your image is unsuitable.
 +  - 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 0xXXXXXXXX +f80000'':
 +<code>
 +=> sf erase 0xXXXXXXXX +f80000
 +[...]
 +</code>
 +
 +  - Now just copy the image to the right place by typing ''sf write 0x1000000 0xXXXXXXXX 0xf80000''
 +<code>
 +=> sf write 0x1000000 0xXXXXXXXX 0xf80000
 +[...]
 +</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>
 +
 +
 +
 +===== 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.
