This tool is a utility for patching firmware updates for sony walkman devices.
It has only been tested on my personal device (NW-ZX300) but should™ work* on all devices with V2 update encryption, listed below:
- NW-WM1A
- NW-WM1Z
- NW-ZX300
- NW-A30
- NW-A40
- NW-A50
- DMP-Z1
* With the exception of the injector, which will only work on the NW-ZX300.
I welcome PRs, or working with people with the following devices to add support for V1 update encryption:
- NWZ-A10
- NW-A20
- NWZ-E350
- NWZ-E450
- NWZ-E460
- NWZ-A860
- NWZ-A850
- NWZ-A840
- NWZ-E470
- NWZ-E580
- NWZ-S750
- NWZ-X1000
- NW-ZX100
- NW-A820
- NW-S10
- NWZ-S610
I'd also love help from anyone with devices other than the NW-ZX300 to add injector support for your device.
first, you'll need to install all packages with:
npm i
then you'll need to grab your update UPG and place it in the root project directory with the name FW.UPG
you can then run the script with ts-node index (if you have ts-node), or you can compile the typescript and run with tsc -p . followed by node index
the script will then unpack all the files in the update into a directory called ./bins
once you finish modifying the files, you can then hit enter in the script. It will detect modified files and repack them into a UPG called FW_MOD.UPG
it will also attempt to run the injector on this modified binary, by copying the file into inject/Data/Device/NW_WM_FM.UPG and running inject/SoftwareUpdateTool.exe
- You are running windows
- The connected device is an NW-ZX300
- The 7th data sector in the UPG is compressed
- The 2nd data sector in the UPG contains a hash for the 7th data sector
While this script was orignally made for my use, i'd love to work with people to reduce and modularize these assumptions.
