This is a really simple to do guide on changing the lockring on both a stock Samsung circle lockscreen and the AOSP lockscreen on ALL SAMSUNG, AOSP & AOKP ROMS and essentially this same method should also work on ALL ANDROID ROMS that are both ODEXED & DEODEXED. I have tested both using my own phone which is a Samsung Galaxy SII GT-I9100 which is running a stock Samsung odexed rom. I have been told that it also works on a Sony Xperia Arc. Your specific rom may have the lockring file named as something else, so you may need to go into framework-res.apk/res/drawable-hdpi (or-xhdpi or -mdpi depending on what device/rom you're running) to find the correct file. If you need help you can attach your framework-res.apk in here and I will do my best to help you out.
This is really easy to do for even a beginner like me, so I’m sure anyone that reads this will be able to do it. There are a few prerequisites to this mod – first of all you need a computer with an unzip style program like 7Zip, your phone needs to be rooted and you also need some kind of file manager (I use ES File Explorer but lots of people say they use Root Explorer). You will also need to have access to a program like Photoshop or Irfanview or Pixlr or Greenfish Icon Editor Pro if you want to change any pictures yourself. I have detailed everything step by step below with pictures so it should be very easy to follow.
Here's the guide…
(Lockrings in 5th post) PLEASE MAKE SURE THAT YOU MAKE A NANDROID/CWM BACKUP BEFORE TRYING THIS - I CAN'T BE HELD ACCOUNTABLE FOR ANY PROBLEMS YOU FACE, BUT I WILL DO MY BEST TO HELP YOU OUT IF YOU DO RUN INTO PROBLEMS
Step 1 - You will need to download the lockring that you would like to use. I have used different styles from HERE and also from HERE and also made my own. You can find some lockring collections made by martintspedersen HERE and by shishircoolin HERE. If you are smart enough to make your own using a program like Photoshop or Pixlr then top work. Just make sure that it is definitely a PNG file. Also make sure that if you want any of it transparent that it actually is (I made this mistake and it didn’t look very good, so I had to get my gorgeous fiancée to fix it up for me, as she is highly skilled in the art of Photoshop). Save the lockring onto your computer somewhere (I keep all of my stuff in a Mods folder) and you will need to modify it soon.
Step 2 - You will need to make a copy of framework-res.apk (which is located in /system/framework) and put it anywhere onto your phone’s SD card. Again, I use a folder called Mods which is easy to locate and remember.
Step 3 - Plug a micro USB cable into your phone and then plug the other end into your computer. Open the directory where you saved framework-res.apk (for me it is GTI9100/Phone/Mods) and move it onto your computer’s desktop.
Step 4 - Now right click on framework-res.apk and select 7Zip – Open Archive.
Step 5 - Within the opened 7Zip archive, navigate to res\drawable-hdpi\ (or res\drawable-xhdpi on a Galaxy Nexus) and locate these files:
For the stock Samsung Circle Lockscreen, find unlockscreen_lock_01.png to unlockscreen_lock_20.png. These usually have a padlock ranging in different stages of unlocking, but I have used the same picture in all of them. You can do the same or modify them slightly, it's up to you.
For the AOSP Lockscreen, find ic_lockscreen_handle_normal.png which is the lock that is visible when a hardware button is pressed, and ic_lockscreen_handle_pressed.png is the same lock with the ring around it that appears when you press the lock.
Step 6 - Change the name of the lockring PNGs that downloaded earlier and want to use to the corresponding file names. For example, I have changed the PNGs in the first picture to use in the stock Samsung Circle lockscreen and the PNGs in the second picture are for the AOSP Lockscreen:
Step 7 - Now drag the renamed PNGs into the res\drawable-hdpi folder. Click yes when it asks you to confirm.
Step 8 - Close the 7Zip archive and now copy your newly modified framework-res.apk back onto the SD card of your phone. Again for me, I use the Mods file so it's easy to find.
Step 9 - Now on your phone, open your file explorer and navigate to where your modified framework-res.apk is. Long press it and select Move To and move it to the System folder on the root directory of your phone.
Step 10 - Now navigate to the System folder and long press on the framework-res.apk and select Properties. You will see this:
Notice how the Permissions is set to rw- rw- rw-? We need to change this otherwise you'll have big problems. Click the Change button and you will see this:
Step 11 - Uncheck the Group - write and Other - write boxes so that it looks like this:
Now click OK and you will see this:
Now click OK.
Step 12 - Now long press on framework-res.apk and select Move To. Move it to the Framework folder within System.
You will see the following warning:
Click OK. Now your phone will freeze. This is ok. It will be frozen for roughly 1 - 1½ minutes, then it will restart.
Once it reboots, you will be staring at your new masterpiece!
Stock Samsung Circle Lockscreen
Ok below are a bunch of lockrings for everyone to use. I have also included the Stock ICS lockring and the Stock Samsung Circle lockring so that if you want to modify them yourself then you can. The other lockrings were made by me (apart from Metallica which was made by martintspederen). Just click on the picture you want and it will open up a new tab where you can download it. Once it's downloaded, extract the files and rename them to the appropriate file name for your particular lockscreen. Requests are both welcome and encouraged!
ALL OF THE LOCKRINGS HAVE BEEN MOVED TO THE 5TH POST, SO PLEASE SCROLL DOWN TO SEE AND DOWNLOAD THEM
Now if this post helped you I would love to know about it, so please post a reply. Even post screen shots of what you have done would be great.
