Problemas na instalação do OpenWRT no Dlink DIR-825

Question

Estou tentando instalar o OpenWRT no meu roteador Dlink DIR-825 com a versão de hardware B1. Eu tenho a versão do firmware: 2.06EU. e eu quando tento atualizar o Firmware e selecione o arquivo de imagem OpenWrt openwrt-ar71xx-genérico-dir-825-b1-squashfs-factory.bin , recebo o erro

The uploaded firmware file may not be correct. You may have uploaded a file that is not intended for this Gateway, or the uploaded file may be corrupted.

If the uploaded file is correct, it is possible that the gateway may be too busy to properly receive it right now. In this case, please try the upload again. It is also possible that you are logged in as a "user" instead of an "admin" - only administrators can upload new firmware.

The Gateway will not be reprogrammed.

Eu realmente não consigo descobrir qual é o problema aqui. Eu estou usando o roteador como admin. Eu sou apenas um usando este AP. Por favor, guie-me se alguém já passou por algo assim ou tenha experiência em lidar com tais questões.

    

Answer 1

Encontrei esta página do fórum do OpenWRT , pesquisando por aí.

Em particular, no final, um cara com seu roteador declara:

Then I booted vista on this notebook and setup the same ip config. I tried the standard d-link firmware upgrade without recovery mode from internet explorer 8 and it still did not work! The solution was, to also use the recovery mode (press reset for ~30s until power blinks orange), only then flashing the downloaded image openwrt-ar71xx-dir-825-b1-squashfs-backup-loader.bin did work. From there it was easy to sysupgrade to my own image.

Thank you! I hope this helps others that try this.

Ele tirou as últimas palavras da minha boca.

Você precisa piscar a imagem usando o modo de recuperação. Leia a página Wiki do OpenWRT:

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.

As instruções também estão na página do Wiki:

1. Get into the D-Link recovery console with the steps below:

   a. While powering up the router, press and hold the reset button until the power LED starts blinking orange (usually takes around 45 (forty-five) seconds )

   b. Set a static IP on your PC to 192.168.0.100/24

   c. connect to http://192.168.0.1, mind the quirks!

2. Click "Browse" and select your OpenWrt image file (openwrt-ar71xx-dir-825-b1-squashfs-factory.bin, this binary image is available in the Backfire 10.03.1rc1 download directory and above)
3. Click "Update" and let router flash the image (don't worry if it reboots before it reaches 100%). The page should display "Device is Upgrading the Firmware" in blue letters with the current percentage in red (with an incompatible Browser it doesn't). Look at the screenshot at the end of this section.
4. The router's power LED should blink orange during bootup, as soon as it stops flashing, you can connect to it
5. Tip! Note that default DHCP will allocate on 192.168.1.x, which is different subnet to the address you allocated above. This is why you can't connect until you change your IP address.
6. obtain new IP from the router via DHCP and follow firstlogin
