I searched the thread and didn't find anyone reporting a similar issue.
I rebooted into recovery today to make a Nandroid. When I used the volume keys and built in soft keys to navigate I got the following error.
E:Can't open /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't open /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
I did some quick googling, and found that other people who had reported this same problem were able to fix it by clearing cache and dalvik cache. I attempted to do this using the built in soft keys and kept getting the same errors. I then switched to the on screen soft keys and was able to wipe the caches and make a nandroid. After wiping the caches I still can't navigate with the built in soft keys, but I don't get the errors anymore.
I may have missed a warning not to use the built in soft keys because I haven't been able to catch up and read the entire thread, but I don't remember seeing anything in the first 500 posts or so. I figured I would mention it in case that was not supposed to happen.
I'm on Task's AOKP, and I'm on the version of Fluxi before 6/4.
