Samsung Galaxy S2 SII GT-I9100

This is an most populat and nostalgic android device from all entire times.According to the android collection this android was included an carrier provider inside the boot animation.To remove the logo and replace with original samsung boot animation it need root and enable boot animation via zip files.

This android It have jelly bean status bar like the Trend Lite which the jelly bean 4.1.2 firmware it have the same easter egg.The root Was performed using cydia impactor.In general it should be rooted with an custom kernel but this method is dangerous since each time booting it show GALAXY SII GT-I1900 With a yellow triangle warning means incorrect kernel or flash ?

As a method to save my stock kernel this method worked.To get the CWM it need access to install the zip without an signature error by signing the zip and apply the signed zip then no more error left.It can be used by adb sideload to load the signed zip file to access the temp clockworkmod.
