Error icuuc36.dll with blackra1n
After solving the problem with blackra1n not found ASL.dll
This time we solve the error of another DLL (icuuc36.dll)
This problem, keeping in theme iPhone has plagued some users intent to
Blackra1n use to run the jailbreak your device.
The solution to this problem, as regards the implementation of Blackra1n is quite simple. It will simply copy the executable of the tool designed by GeoHot Common Files within the directory located within Program Files. More precisely, the paths to copy the executable Blackra1n depending on the version of operating system currently in use are:
Windows 32bit: C:\Program Files\Common Files\Apple\Apple Application Support
Windows 64bit: 64 Bit – C:\Program Files (x86)\Common Files\Apple\Apple Application Support
Once copied Blackra1n in the right path you can run it from there or create a desktop shortcut to solve the problem calmly and run the jailbreak.
