following commands:

Patched kernel written to kernelcache.release.n90.patched
Created script make_ramdisk_n90ap.sh, you can use it to
(re)build the ramdisk
The script creates a patched kernel file called
kernel-
cache.release.n90.patched
to the current working directory. For the iOS 5
IPSW file, it also creates a script called
make_ramdisk_n90ap.sh
to build the cus-
tom ramdisk. Pay attention to the file names because they may differ depending on the
iOS device model.
Building a custom ramdisk
Give permission to execute the
make_ramdisk_n90ap.sh
ramdisk build script and
execute this script to create the custom ramdisk as follows:
$chmod +x make_ramdisk_n90ap.sh
Before executing the script, edit the file and fix the iOS SDK path as follows:
$sudo nano make_ramdisk_n90ap.sh
As we are using iOS SDK 6.1, append 6.1 to the
for
loop, as shown in the following
code:
for VER in 4.2 4.3 5.0 5.1 6.0 6.1
