Sorry if this is explained in detail somewhere else, but I am relatively new to the world of rooted Droids. I have had BB v0.4 running on my Droid for about 2 weeks. In that time, I have installed Blue Energy and am currently running the RedLINE theme, both of which are awesome.I am happy and love the new world of rooted Droids that has opened up to me. I feel I have a decent handle on peeling back the programming layers to customize my phone, but I have a problem that I can't seem to figure out. I am trying to install some different kernels ( i currently run 184.108.40.206-g103d848) that is a part of BBv0.4). I am trying to install a low voltage kernel from p3Droid to see how my phone handles it. I downloaded the kernel as a .zip file straight to my SD card's main area, not in a sub folder. I go into ROM manager hit "install from SD card", find the file, I already have a backup of my existing ROM so i don't check that , and I don't check to wipe data and cache, I reboot and get a repeating message that the E: won't mount (which I know means the SD card) it then boots into ClockworkMod Recovery v220.127.116.11. Here I should share that I had this problem of the SD card not mounting when I boot, when I installed the 2 themes I have used. After 10-15 tries eventually the SD card mounted and the themes were installed and everything was fine. I can't seem to get the kernel to install because I can't get the SD card to mount. MY QUESTION IS THIS: When the SD card does not mount, shouldn't I be able to go into "install zip from SD card" while in ClockworkMod Recovery, find the .zip file and install it from there? The problem is that all of the rooted .zip files I have downloaded (BB v0.4, RedLINE, Blue Energy, and the P3Droid kernel) are all sitting in separate .zip files out in the open on my SD card. I see them when I search the SD card from ROM manager, I see them when I search the SD card on Astro, but when I am in ClockworkMod Recovery, and I go into the SD file to download the kernel, not only is that file not there but none of the .zip files on my card are listed. What am I missing? It would be nice to just install from ROM manager, but the posts are filled with non-mounting SD card issues like I have with various theories of the reason for the problem. But it shouldn't matter b/c I should be able to install the file from ClockworkMod right? Why isn't the file listed there in recovery when the file IS literally there on the SD card. Or am I totally missing something. Any help or insight would be greatly appreciated.
