With all the excitement surrounding the Jelly Bean source code release, and the subsequent flurry of development work, it was only a matter of time before someone started modifying it. While more involved modifications have yet to make their appearance, users can now modify the Jelly Bean lockscreen on the Amazon Kindle Fire.
Instead of simply providing various recovery-flashable update.zip files, XDA Senior Member Josepho1997 has written a short tutorial explaining how users can do it themselves. This is a nice, simple, and introductory tutorial into theming for anyone who wants to give it a shot. Users will need Photoshop or some other image editing program, such as Gimp. Additionally, users will need 7zip. From there, Josepho1997 runs through all the files that need to be altered for the lock screen to get completely themed. For Photoshop users, Josepho1997 also gives some tips on how to easily change the colors without too much work. Then users re-package the files, and use their favorite root explorer to push them to /system.
While this was originally intended for the Kindle Fire, due to the generic nature of the modifications, this method could actually be used on any Jelly Bean lock screen. Users looking to get started in the world of minor theming should head over to the original thread.simlock, calculators, unlock, codelg ultimate remover v0 8 9 rar
