How to extract *.u Firmware under Windows

[ginny]

The older *.trx Firmware format could be easily extracted using 7Zip. Firmware for e.g. ASUS RT-AC86U or RT-AX92U uses a new format with a ".u" extension. Does anybody now how to extract this firmware type under windows.

Thanks in advance for your help

All of my AC86U firmware downloads as .zip and extracts to and installs from .w. I must be missing something.

Hi OE
Thanks for your reply. But I want to extract the .u firmware file itself as I can for .trx files with 7Zip in this example

Using 7Zip under Windows no problem, but I'm searching for a tool that allows me to achieve the same for .u firmware files

As @OzarkEdge said, the firmware files have a .w extension. I don't know of any tool that can read those.

Can't be done under Windows. Under Linux it requires multiple tools, as you need to handle UBI file containers, as well as JFFS2 partitions.

Thankyou RMerlin, so I think this thread can be closed
