How to install git or other apps on WD MyCloud Mirror

How-to-git-WD-MyCloud-Mirror.md

You got WD MyCloud Mirror or so, and you don't have some 3rd party apps - like GIT\Antivirus and etc. If you just take an app from other model, like WD MyCloud EX2 and try to install it on WD MyCloud Mirror you'll see: "Failed to install blah-blah-blah" - FAIL! But!

first of all you need some device,file and tool:

1. WD MyCloud Mirror.
2. App that you need from other model. it my case - it's GIT - http://downloads.wdc.com/apps/WDMyCloudEX2/git/WDMyCloudEX2_git_1.40.bin
3. Hex Editor - WinHex\wxHex\you name it

how to make this works:

1. open the file WDMyCloudEX2_git_1.40.bin in Hex Editor
2. replace first blocks from 1 to 7 4B 69 6E 67 73 43 61 5A (KingsCaZ) to 47 72 61 6E 64 54 65 5A (GrandTeZ)
3. save it
4. go to WD MyCloud Appstore and install it over manual install
5. Logint over ssh and check:

root@WDMyCloudMirror root # git --version 
git version 2.0.1
