Hi I have new model of router called D-Link DIR-853.
I have found some information about it here: http://www.dlink.com.tr/lv/products/9/2238_b.html5
I was able to access it using telnet and got some more information using console: https://gist.github.com/a2nt/10b96f421d18f501ed238a063601291e4
Looks the same as D-Link DIR-860L rev. B1 by specification so I think it is possible to install LEDE.
Also I have wrote a message to dlink and got testing version of firmware:
file -k ./DIR_853_MT7621AT_3.5.0_internal.bin
./DIR_853_MT7621AT_3.5.0_internal.bin: u-boot legacy uImage, DIR_853_MT7621AT, Linux/MIPS, OS Kernel Image (lzma), 1724041 bytes, Fri Mar 16 13:51:16 2018, Load Address: 0x80001000, Entry Point: 0x803A10C0, Header CRC: 0xBA54E809, Data CRC: 0x4D6C3FBC\012- data
How to build LEDE image using this information?
