Alright, I hope I have this in the right place. I just recently flashed the TerraSilent Kernel for the Galaxy Player 4.0 US version. The Flash went fine, but my device was running extremely slowly. A re-flash didn't solve it either. I figured that wiping the cache partition might solve the problem - I decided to do this before running a backup, since no important data is stored in the cache (...right?), and since I was worried that backing up while I had this problem could make things worse - so I went ahead into CWM and did just that. Then, it reboots, and I nearly get a heart attack. The stock wallpaper is back, it's using the default launcher again (I had LauncherPro installed), and pretty much only system apps work, all the others have an icon with an SD card on it, and when clicked on, it says something like "application not installed". I did some searching, and it seemed like a reboot might help (although I didn't find anyone with a problem like mine anywhere). The reboot didn't do anything, so now I have it shut down, so that nothing can happen. The odd thing is, it doesn't seem to me like the system messed up and did a full wipe instead, either, because a couple of things I have are still there - for example, some of my bookmarks I made on the homescreen while still using the default launcher are still there. I'm really confused because I have wiped the cache partition before, when I was still on an unmodified stock kernel, and everything stayed the same, the way I thought it was supposed to. And now this happens. What do I do now? I exported my absolute most important data (Astrid Tasks and Calendar) before I installed TerraSilent (but I obviously wasn't able to do a full backup because I wasn't rooted, I figured installing TerraSilent would root it), so my absolute most important data is on my computer. I also did a simple file backup of the internal USB storage and external SD card to another computer before flashing TerraSilent. However, there is still a good deal of data still need, and a lot of data that would just be a pain in the rear to recreate, not to mention my (valuable to me) game data. What did I do wrong - or did something in the system mess up? And - what do I do to get back to where I was before?
