Consult flash.layout for a better understanding.
There are two ways of installing firmware, either by using normal D-Link firmware update web-interface or by using firmware recovery mode.
Installation using firmware update page
Note: Since original Firmware 2.05WW Build: 05Beta01 it is not possible to flash OpenWrt via the firmware update page. (worked on a B2 revision with Ubuntu’s Firefox in 2.05NA and 2.06NA) It looks like Firmware 2.01EU behaves the same way. Please use the firmware recovery mode instead.
Note: This method works for revision B1 with Firmware 201EUB15, once the firmware identifier is fixed as follows: sed ‘s#00AP94-AR7161-RT#01AP94-AR7161-RT#’ –in-place openwrt-XX.YY.Z-ar71xx-generic-dir-825-b1-squashfs-factory.bin. Use the following to get the firmware identifier: hexdump -C DIR825B1_FW201EUB15.bin | tail -3
Note: This method works for revision C2 with Firmware 3.00 using Ubuntu’s Firefox. I used openwrt-ar71xx-generic-dir-825-c1-squashfs-factory.bin
Installation using firmware recovery mode
Phase 1: OS specific quirks
Note: The firmware recovery mode has following quirks:
Phase 2: General steps
Flash Layout
First, for familiarity you can look at the concept of flash.layout. It is also recommended that you know flash layout of DIR-825 before generic.sysupgrade, generic.backup, generic.debrick or failsafe_and_factory_reset.
| D-Link DIR-825 Rev B Flash Layout | ||||||||
|---|---|---|---|---|---|---|---|---|
| Layer0 | m25p80 spi0.0: s25sl064a 8192KiB | |||||||
| Layer1 | mtd0 u-boot 256KiB | mtd1 config 64KiB | mtd7 firmware 6208KiB | mtd5 caldata 64KiB | mtd6 unkown 1600KiB | |||
| Layer2 | mtd2 kernel 1024KiB | mtd3 rootfs 5184KiB | mtd8 caldata_copy 64KiB | |||||
| mountpoint | / | |||||||
| filesystem | overlayfs | |||||||
| Layer3 | mtd4 rootfs_data 3328KiB | |||||||
| Size in KiB | 256KiB | 64KiB | 1024KiB | 1856KiB | 3328KiB | 64KiB | 1536KiB | 64KiB |
| Name | u-boot | config | kernel | rootfs_data | caldata | caldata_copy | ||
| mountpoint | none | none | none | /rom | /overlay | none | none | none |
| filesystem | none | none | none | SquashFS | JFFS2 | none | none | none |
*Note* The partitions “mtd1 config”, “mtd5 caldata”, “mtd6 unkown” and “mtd8 caldata_copy” contain vendor specific raw (without filesystem) config values about your router, like WiFi calibration data, MAC addresses, etc. It’s a good idea to make a backup from them. Similarly, “mtd0 u-boot” has some specific codes for Dir-825 (e.g. its “firmware recovery mode”); So you can backup that partition too.
*Note2* You can check mtd partitions of your router yourself by using commands “ cat /proc/mtd ” and “ dmesg ”. Refer to this link.

Physically breaking into the DIR-825
Note: This may void your warranty!
To remove the cover simply:
To remove the board from the casing:
Serial
| PIN1–>3.3V PIN2–>RX PIN3–>TX PIN4–>GND |
Remember to use 12V↔3.3V serial port voltage converter or you might break the router by over-voltage.
COM port settings: Speed:115200, Data bits:8, Stop bits:1, Parity:none, Flow control:none
How to connect to JTAG interface, and how to reflash the device with JTAG tools
See port.jtag for more JTAG details.
See the LED section in /etc/config/system on general LED configuration.

Repair LEDs after flashing OpenWrt
If you want to see the BLUE POWER ON and the BLUE GLOBE ( planet ) blinking when it receives information, then do the following setup:
For UCI configuration of the LEDs use this set of commands:
After rebooting the device this setup becomes active.
Buttons
The D-Link DIR-825 has two buttons:
| BUTTON | Event |
|---|---|
| Reset | reset |
| WPS | powersave |
The WPS (WiFi Protected Setup) button is located at the right side (or the top when standing) and can be easily pressed with a finger. Also the WPS LED is integrated into the Button. For some unknown reason this control is named powersave in various places.
The Reset button is located at the back and cannot be pressed with a finger, you need a small item to push it in.
Switch Ports
Numbers 0-3 are Ports 4 to 1 as labeled on the unit, 5 is the internal connection to the router itself.
| Port | Switch port |
|---|---|
| CPU (eth0) | 5 |
| No port | 4 |
| LAN 1 | 3 |
| LAN 2 | 2 |
| LAN 3 | 1 |
| LAN 4 |
Hardware Mods
Second USB port
It was reported that in order to enable second USB port it is sufficient to solder in two straight bridges in place of L66 (take a look to the corresponding photo in the “Photos” section). After that you will need to solder in second USB header or – easier way – to solder in short-tailed female USB type A connector (sample photo is also available in the “Photos” section).
In the stock firmware, after you have soldered the bridges and USB head, if you connect a USB device (e.g. a USB Flash Drive) to the second USB head, the USB LED will turn blue.
Discussion and more information can be found in this thread.
128 MB RAM Mod
vavasik did this mod and reported his experiences in this thread.
Next to the soldering, the bootloader (U-Boot) and the calibration data partition has to be changed, because the D-Link bootloader/calibration data partition does not start with the 128 MB RAM. He used the bootloader/calibration data partition from Netgear WNDR3700. It’s done through a full reflash, check the forum for the binary. It turn the D-Link DIR-825 into an Netgear WNDR3700.
The Netgear stock firmware does not recognize the 128 MB RAM, it only shows/uses 64 MB RAM, but it starts.
An detailed tutorial from vavasik can be found here.
Don’t do this if your are inexperienced in soldering, you will for sure destroy the contacts→Trash!
Connection Information
Other Info
Feel free to add here any info we haven’t covered yet! Thank you!
I was able to upload the openwrt-ar71xx-generic-dir-825-b1-squashfs-factory.bin in recovery mode with Internet Explorer with compatibility view enabled (menu Tools/Compatibility View). Without it it was loading forever. Other browsers (Chrome, Firefox, Opera) were not working. Tested with Windows and Linux. Also I switched my 1Gbit cart into 100Mbit mode.
It may be necessary to run the original firmware and configure the device at least once. I flashed the router right away using the firmware recovery interface which resulted in configuration problems in OpenWrt. All wireless network devices did not have valid MACs instead they used 00:00:00:00:00:00 and refused therefore to work properly. Even trying to read the MAC from the sysfs failed. After flashing the original firmware and configuring the device once using the D-Link Webinterface everything worked as expected after flashing OpenWrt again.
Besides flashing in recovery mode from a MacBook Pro using Google Chrome and the default Gigabit plug worked just fine!

[edit] Выбор версии прошивки для DIR-825 Rev.B
ВНИМАНИЕ! Прошивать надо обязательно с интернет експлорера бо на любом другом возможны проблемы
( Эта ссылка, к сожалению, уже не работает. Ищите вручную на сайте по названию DIR-825: http://dd-wrt.com/site/support/router-database dissertation writers)
1. Выбираем последний релиз.
2. Находим директорию dlink-dir825-revb.
3. Скачиваем файл factory-to-ddwrt_WW.bin (похоже все продающиеся официально в России имеют релиз WW).
Теперь готовимся сообственно к прошивке 🙂
[edit] Прошивка роутера DIR-825 Rev.B
Прошивка производится через проводной интерфейс.
1. Зажимаем Reset любым подручным инструментом и ждем
45 секунд до момента, когда светодиод питания станет оранжевым и будет моргать с частотой 1 раз в секунду.
2. Выставляем в настройках сетевого подключения:
3. В браузере набираем:
Видим тривиальную страницу для загрузки прошивки в роутер.
Кстати в отличии от информации в интернете были опробованы Internet Explorer 8, Opera 10.10 и Firefox 3.6. Все три отлично справились с заливкой прошивки в роутер.
4. Нажимаем кнопку "Обзор" и выбираем скачанный файл прошивки.
5. Нажимаем кнопку "Save" и идем нервно курить/пить кофе.
Процедура заливки занимает примерно 4-5 минут с учетом самостоятельной перезагрузки роутера.
После загрузки DD-WRT светодиоды питания и WiFi не горят, светодиод WAN светится фиолетовым цветом
[edit] Доступ к роутеру после прошивки
1. Выставляем в настройках сетевого подключения:
2. В браузере набираем:
Радуемся и начинаем играться с настройками.
Для тех, кто дружит с Линуксом по умолчанию поднят Telnet по адресу 192.168.1.1:23.
[edit] Восстановление оригинальной прошивки
Восстановление проводится тем же способом, что и прошивка DD-WRT, с той лишь разницей, что Reset нужно делать по системе 30/30/30 (зажимаем на 30 секунд, не отпуская Reset выдергиваем питание на 30 секунд, не отпуская Reset подключаем питание и ждем 30 секунд, видим оранжевый мигающий светодиод питания).
