    I have uploaded the file to my sd card however when I select recovery I get to choose the folder that my files are in but I only see folders and not a specific file to load, It does not seem that I can actually click on a file, am I doing some thing wrong ?

    I select recovery then the folder that has the copied files inside then that takes me to the sub directory of files which are META-INF, Patch,Recovery and System.

    If I click on any of those folders it takes me to other folders or the end of that directory ?

    Any advice ?
