DLink DIR-853 A3

Hi @mitsos,

It seems that @s_2 has created a very easy way to encrypt the factory file. I have not tested the file itself as I do not own the device. I just downloaded the factory file for the DIR-853-A3 from the openwrt and encrypted it with his tool. You need to be aware that bricking your device will not be recoverable without using a USB TTL.

Before sharing the file I want to share how to use the tool as the download link expires after a while.

This is taken from here

git clone https://github.com/s-2/firmware-utils.git
cd firmware-utils
git checkout dlink-sge-image_2k23
cmake .
make dlink-sge-image

Then use the tool to encrypt the image. Running the tool will give help on how to use it. For the snapshot version these commands can be used.

./dlink-sge-image DIR-853 openwrt-23.05.0-ramips-mt7621-dlink_dir-853-a3-squashfs-factory.bin openwrt-dir-853-enc.bin
