We bought the router DIR 853 ver A2 and we would like to make it work with Open VRT, can anyone help me?
If it's not there, it's not supported.
But from what we understand, we can do and make it work, can something be done?
Changing some settings?
Don't know, I found pretty much zero info regarding an A2 revision, so you'll probably have to open it up, and check what chipset it's using.
I opened the device to see the chipset information, but what I found on the device's motherboard is DIR-853_A1 REV 1.0.
There are two black chips on the board
The first chip is written NANYA 1927 NT5CC64M16GP-D1
91365400EP F TW
THE SECOND CHIP
MEDIATEK
ARM
MT7615DN
1923-8FSL
ACMS1FMS
MT7621 is a supported SoC, so the router's probably supportable, even thought it's currently not.
https://deviwiki.com/wiki/D-Link_DIR-853_rev_A1
The A3 revision of the 853 is supported, but you shouldn't blindly flash the A3s fw onto an A2/A1.
So I saw that the DIR 853 A3 already has it in the approved devices, but I'm not sure if I can work on this DIR 853 A2 device
Do you think possible?
Can't use another devices fw without further investigating, you're risking a brick.

Hey,
I'm doing some very detailed research to understand, but I still haven't been able to get it to work.
Get what to work?
Hi @ads119
If you are happy to compile your own image then I am sure you would be able to get it to work easily.
Having said that you should first get a backup of your whole device. If you have access to the console it would be better (to be able to see the logs)/
The A1/A2 is just the A3 with a NOR flash (A3 being NAND).
@Lucky1 is the expert on these devices I am sure he'll be able to provide more guidance.
My advice is to look at the pull request for the A3
And do something similar with the A1. Replace the Nand part with the one from your device (which should be the same with other dlink devices
&nand {
status = "okay";
partitions {
compatible = "fixed-partitions";

read-only;
};

read-only;

read-only;

partition@4980000 {

};

Do you have access to the console? Do you have a bootlog for your device by any chance?

D-Link Model Name: DIR-853 Hardware Version: A2 Firmware Version: 1.20
I access the router through the URL http://192.168.0.1 and inside the console that I access via the Web, I managed to get some log information.
Follow the log below:

I cannot access via USB, or serial model does not have this possibility, can I access a web interface via cable or Wireless?
But I sent the logs that I got, can you help me? We bought a lot of this equipment and I need it to work with OpenWRT and I still don't understand where to start..
Thanks, I guess you don't have access to the console. It would have been useful to have a complete bootlog.
Does the device have a recovery function? Can you boot with the reset button pushed in and see if you get a blinking led light please?
Hi @kar200 does have the recovery function.
Turning on the device with the reset pressed, the orange light starts blinking and enters the screen below.
Hello, I'm still researching how to make it work, it seems that the difference between the DIR 853 A3 for my DIR 853 A2 device is the memory, but I don't know how to make the compilation and change this information in the .bin file to test.
how do i compile and make the changes you mention in the post above?
You can help me too, I need to make this equipment work DIR 853 A2. Thank you all in advance.
