[MOD] Custom Boot Screen *SGS II I777*

---

Hi guys/girls,

I picked up an I777 SGS II the other day and decided to extend my development of the SGS boot screen MOD to it and was able to port it the same day as not much has changed in the way the param.lfs operates. I know this works just fine on the AT&T I777 SGS II in which the param.lfs calls for logo_att.jpg but if it fails, you can always re-flash a stock param.lfs to restore the boot screen which I have also included. I have written this for (I897, I9000, T959, T959V, I9100 and now I777). Per XDA's rules, I'll just attach the RAR package as an upload at the bottom of this post.

If you appreciate my work, just tap THANKS, SUBMIT THIS TO PORTAL or DONATE me a drink or two if you are feeling generous. Here is the read me in case you don't want to open it with an additional text editor:

Thanks to Entropy512 for the stock param.lfs dump...

REMEMBER, THIS SCRIPT INSTALLS THE LATEST BUSYBOX INSTALLER, THIS MEANS IF YOU DIDN'T HAVE BUSYBOX INSTALLED, YOU MUST OPEN THAT INSTALLER AND ACTUALLY INSTALL BUSYBOX. IT INSTALLS AN APK TO USE TO INSTALL BUSYBOX, IT DOES NOT ACTUALLY INSTALL BUSYBOX ITSELF DURING THE SCRIPT.

ONLY USE THE LATEST BUSYBOX BY STERICSON TO ENSURE THIS WORKS BEST. IF YOU DON'T WANT TO USE THE SCRIPT FOR THE LATEST VERSION, BE SURE TO DOWNLOAD THE LATEST FREE INSTALLER OR DONATE VERSION IN THE MARKET BY STERICSON.

If the script doesn't work for you, it should if you have ADB installed, a rooted device plus the latest BusyBox (no offense but it's user error otherwise) just use root explorer to paste your logo_att.jpg in /mnt/.lfs AFTER running the custom param file via ODIN.

I'll get a video up for this model soon on how to do this without any product placement so it's XDA approved.

Just tried to do this, got an error when it tried to install busybox (already installed, that's ok), but then I get this error:

cp: can't create '/mnt/.lfs/logo_att.jpg': File exists

I didn't get an the SU request either

Sounds like you didn't flash the custom_param file with ODIN.

Is this a custom splash screen? If I'm correct

Out of curiosity, what does the custom_param file do?

Change logo.jpg to be writable?

Good work dude

It changes logo_att.jpg to be writeable in this case for the I777. But yes I've removed the file via hex-editing which is the only way to allow for a new one to go in it's place. Fortunately for us Samsung has not changed anything since I discovered this loophole way back in the Captivate days.
