Where are custom kernels being flashed to in internal memory? I've unzipped zip files for custom kernels and noticed that the majority of the files that are being applied are in a /kernel folder. However that folder is unlisted when listing the root directories using both Root Explorer and ES File Explorer. Where is this /kernel folder?
The kernel is part of the "boot image", which is stored in a separate partition in the flash memory, not in a normal file. See http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images
