[Galaxy S 4 Q&A, Help & Troubleshooting] nniicckkss:
You'll need to be rooted to try this, and I'm sure you will need to be running a deodexed ROM based around original ROM.

I have edited the SecWallpaperChooser.apk three ways to try to get the Wallpapers working the way I tried to explain in my theory a few posts back. Here is what I've done;

I've created a new Wallpaper and added it to the SecWallpaperChooser.apk, I want all of the attached .apks to work, but if not, I'm hoping that at least one will!

The original .apk file contains 7 different wallpapers, labelled 'fhd_01.jpg' (main WP) and 'fhd_01_small.jpg' (I guess this is a thumb), and the are numerically ordered up to '08. there is no '07' in the .apk I'm using (from the original deodexed I9500 system dump - should be the same for I9505, right?), so the file names go up to '08'.

Please extract the .zip file at the following link, it will contain three folders, each folder is labelled as follows:

7Included - I've added my new WP to the file and added it as filename '07', all original WPs are included too.

8Overwrite - I've added my new WP by overwriting the original file number '08' (nobody used the photo of twigs, do they? :p), all other original WPs still included.

9Added - I've added my new WP as filename '09', all original WPs are still included.

What I think you'd need to do with these files is:

Navigate to the root of your device: system > app - and look for the file called 'SecWallpaperChooser.apk' - back this up somewhere.

With root access active on your favourite file explorer app, copy the first file you want to try out from one of my folders, don't rename it though, and paste it over the original 'SecWallpaperChooser.apk' in the system > app folder. Set the permissions to 'rw-r--r--'.

Exit your explorer app, then reboot your device.

It would be good to wipe cache/dalvik if you can, but I don't know if we have custom recovery yet to be able to do this - is there another way to do this - does it need to be done...? I'm not sure. If you're not sure too, then please don't try this.

Hopefully, the next time you try to set a wallpaper, you will see my new wallpaper as an option too.

This is the test WP I made:

If it works, all you need to do then is make your own WP and add it to the app. A bit long winded, but if you don't change your wallpapers very often then it doesn't matter. Depending on which of my .apks work, you might be able to add a few new wallpapers to the .apk. I'd keep to the original WP dimensions too, as per original image files.

Here's the link to my modified .apks - fingers crossed... http://db.tt/bsbEFMJz

If none of these work, then just reinstall your original backed up .apk.

I haven't tried this so please test it at your own risk, I won't be able to help you if you get into issues, and if you do, please don't blame me - I'm only trying to help. Maybe you shouldn't try this if you don't know what you are doing.

If you do try this, then please let us know how you got on. Thank you.

:cool:

EDIT: None of the above worked, but I decompiled the wallpaper app and swapped out some of the stock wallpapers with my own (and renamed them correctly), then recompiled it again, and now I have my own wallpapers with transparent status bar and no modified System UI, and I don't have transparent top bar in apps (which can look a bit odd sometimes) like you can get in the popular transparency mod to the System UI.
