Could you please guid me with the steps?
When I try from CLI of router no commands were working. It says command not found ( eg apt-get)
Hi,
have a look at this post. Make sure you use the correct file as there is no check/safeguard in this process.
Please make sure you use the correct file. This process does not have any check and will just flash whatever you provide in the command line.
The file you want to use is this one:
That worked.. you are the best @kar200
One suggestion I would like to see in the future is when we do upgrading, WiFi radios are disabled status. Also not sure which one is 2.4 and 5 Ghz. Good someone fix it in the future
Glad to see it worked.
That's just because you flashed from Padavan which stores the settings differently from Openwrt. Next time you upgrade you will use the nomral sysupgrade file and if you choose to keep the config your router will upgrade the firmware and keep the same config

i am using OpenWrt 23.05.0-rc4 on dlink-dir-853-a3 i am facing Internet speed issue on 2GHZ wifi... but on 5GHZ working full speed internet.... before this OpenWrt i was using stock FW and its give me full speed on 2 GHz.... Do you have any solution or can you give me a stock FW so i can go back on stock FW
I missed your we.tl upload every time and I finally got to execute your instructions in this post, but I'm getting Input File openwrt-dir-853-enc.bin could not be opened. errors.
$ ./dlink-sge-image ~/Downloads/openwrt-23.05.0-ramips-mt7621-dlink_dir-853-a3-squashfs-factory.bin openwrt-dir-853-enc.bin
Input File openwrt-dir-853-enc.bin could not be opened.
Any insight wh that might be the case? Just in case this might be some sort of dir permission error or something, I tried with sudo to the same results.
Did you try to upgrade to the latest version of 23.05 (non RC) I don't think it'll make a big difference but it might be worth a shot.
Also look for devices with similar wireless card (MT7615DN) and see what kind of settings other people are using that might be working for them.
What kind of speed are you getting on 2Ghz and what were you expecting?
It seems I posted and incorrect command line. I forgot to add the device model.
This is with the latest stable openwrt for DIR-853. You can skip the build part. I will update the other post as well.
git clone https://github.com/s-2/firmware-utils.git
cd firmware-utils
git checkout dlink-sge-image_2k23
cmake .
make dlink-sge-image

Thank you for the correction. After the encryption, the flashing finished without any incident. I'll check it out more extensively later but for now, everything seems to be working fine.
I also want to reiterate, the YouTube video posted a while back is misleading because it skips over encrypting the squashfs-factory firmware. Without doing this, the stock frmware updating page will just error out with upgrade failure message. The download link he provides is also the regular builds available on OpenWrt, which are of course not encrypted. Since he redirected a comment about the error to this thread, to anyone coming from there: the last post is the solution, you need to follow the instructions to build the tool to encrypt the factory flashing image.
Here are the encrypted file to use on the factory D-Link web UI directly: MediaFire (I think link is live for 14 days?) and Anonym File (they say it's indefinite, but who knows)
How I generated it, using factory image on firmware selector and s-2's tool:
$ ./dlink-sge-image DIR-853 ~/Downloads/openwrt-23.05.0-ramips-mt7621-dlink_dir-853-a3-squashfs-factory.bin ../openwrt-23.05.0-ramips-mt7621-dlink_dir-853-a3-squashfs-factory_enc.bin

Apparently s-2's patch to the firmware-utils got merged, so maybe the images on firmware selector will already be available in its encrypted form. But until then, you can use the links here to get it without having to build the tools yourself.

Hi kar200
should I try and include the DIR-853-A3 in my PR with the NOR flash devices ?
ill need someone else to test this one

Hi @Lucky1 ,
Sorry for the late reply I was away. I saw that it was merged already. Thanks for including the A3 it would make it much easier now for everyone to just download the factory image and flash it directly from the web interface.
I am not sure I understand your question but I don't think there is an A3 version with NOR flash (they are all NAND).

This is great news. But is there a way to easily tell when the images on firmware selector is going to be built encrypted?
I just added it
it's the only NAND one
tho I didn't get feedback on if it worked ?
all the other NAND ones need a private key
from the next version the
Recovery images are for the recover interface and
Factory images are for the D-link web interface
lots of the NAND ones will now just have a Recovery file
I'm hoping that recovery comes up in the firmware selector
Unfortunately I don't have the device to test it although it seems it worked before with the tool provided by @s_2.
I guess we will find out. The good news is that it either woks or does not (it should not brick any device).
Tanks again!

The new snapshots seems to now build both images. From what I see there is an extra image file (recovery) being built.
Hopefully someone can test this image to confirm that it is indeed working
Firmware selector also seems to work.
Recovery = non encrypted
Factory = encrypted

i am facing problem to admin login & wifi DIR853-A3 stock FW , as i lost/missing my router Device info Label (Sticker). i am beginner so any easy way to recover it ? thanks
If you have admin access to the device from the web interface then you can install openwrt - login as admin - download the partition that contains the password (sorry cant recall which one) and then use a Hex editor to read the password.
If you lost admin access then no easy way. You will need to use the console access.

The flashing instructions can be found in the git commit -- it involves connecting the serial console referenced by @kar200, and it doesn't require the stock firmware's password. Then you can install OpenWrt and you'll be in known territory for the default state (username root, no password, wifi disabled -- connect via ethernet).
You won't be able to login to the stock firmware if you don't have that password, so unless it is known by the person from whom you got the device, you cannot do anything other than consider flashing to OpenWrt or e-cycling the device.
