I successfully went through Hashcode's instructions for installing the second bootloader, rooting, and installing TWRP, and one of the Cyanogen nightly builds. All was working fine until I decided to try and go back to Kindle mode by restoring the original boot system and recovery images. The Kindle still seemed to work fine with the Kindle apps and I could use my Prime account. Now I am trying to switch back to Cyanogen. My problem is with TWRP. It does not see the sdcard files correctly. I have added some folders and zip files to the root of the sdcard but TWRP does not "see" the new files. It is like it has an image of the very original directory structure. How do I get TWRP to see the new files ????
