Why can't I Jailbreak my iPhone 5c?

If you're getting "cannot retrieve package info" in evasi0n, this fix is for you:

Evasi0n workaround

Mac OS X:

• On your Mac, go to your “Applications” folder.
• Now navigate to the “Utilities” folder.
• Launch "Terminal".
• Type "sudo nano /etc/hosts" (without quotes) and hit return.
• Enter your password. You won’t see anything change on-screen when you type your password; this is normal.
• Use the down arrow key to scroll to the bottom and enter a new blank line without a # at the beginning.

Type this line there, exactly as written:
97.89.129.19 evasi0n.com

• Exit the nano editor by pressing Ctrl+X, followed by Y, and return.

Close Evasi0n if open, then open Evasi0n. You should be able to jailbreak. Once jailbroken, follow the above steps to erase the line you added.

Windows:

• Click Start, followed by Programs and Accessories.
• Right-click Notepad and choose “Run as Administrator”. On Windows XP, if your account is an administrator, you can simply click to open Notepad, otherwise you’ll need to choose “Run As...”
• Click “Open” from File menu.
• Browse to C:\Windows\System32\drivers\etc.
• In the dropdown menu that says “Text Documents (*.txt)”, select All Files.
• Double-click on “hosts”. (or if you use Internet Connection Sharing, "hosts.ics")
• Use the down arrow key to scroll to the bottom and enter a new blank line without a # at the beginning. .

Type this line there, exactly as written:
97.89.129.19 evasi0n.com

• Click “Save” from the File menu. Make sure the file type is "all files (*.*)" and not .txt (or if you use Internet Connection Sharing, ".ics")
• If Windows complains that the file is in use by another program, temporarily disable your antivirus and try again.
• Close Evasi0n if open. Open Evasi0n and jailbreak.
• After jailbreaking, repeat above steps but delete the line you added.

Enjoy!
