    I did everything the guide says but I never got asked to update when I loaded the bootloader

      Did you rename the file to PC36IMG.zip?

      Sometimes, the Windows doesn’t show the file extension, therefore, if you rename the file to PC36IMG.zip, it’s actual name should be as PC36IMG.zip.zip. (note the double ZIP)

      Follow the tip I gave above and you should be good to go.

    Do you have to have the SD it was rooted with in the phone??

  • Jordan

    what if it shows a $ sign instead of a # sign in the command prompt?

    • http://www.techlisten.com Mahesh Makvana

      It means the command that you’ll type won’t be executed as Admin (Root). In simple words, if you don’t get a # sign, you can’t uninstall a system app.

      Hope you get it!
