[MOD] Custom Boot Screen *SGS II I777*

[connexion2005]

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.

That's correct... The first one you see when powering on. I refer to the other one as the boot animation. For reference the kernel screen is only in between the boot screen and the boot animation is only changeable during a compilation of the kernel. This tutorial would be way to involved which is why I never made it.

@connexion2005

I got My SGS2 last Sunday. Nice to see familiar folks coming from SGS.

Awesome work as always... It worked like a charm. Thanks!

I've attached my logo file in case someone is interested.

 

[clown_luv]

Con can you show us the pic used and this will not affect my kernel correct?

Custom Boot Splash!

Awesome work Josh...Thanks for bringing this over to the AT&T version of the SGSII for us! You have some good stuff going on over at MTV (No pun intended) keep up the good work for all the phones...Hope to see more coming soon for this one!

 

[connexion2005]

Thanks! More coming soon as you'd expect including full JTAG support (will take some work though as surprisingly they changed the board from the SGS I9100!)

 

[clown_luv]

So con I flash in Odin and what is the splash screen pic? ? ( just wanna know and what slot PDA?

I think there are a number of hidden under-the-hood changes - NFC is not the only one.

If you've opened the device up - Is there an Si7409 (FM chip) or not? If not, I'll give up on trying to probe for it.

Another difference is that even though the MAX8997 PMIC Samsung uses in our phone has a battery charger, in the I777, Samsung has offloaded charging to a separate chip (MAX8922). Which means we don't get all of the charge current control hacks available to the I9100 unless there's some way to restore control to the 8997. (not likely)

 

[connexion2005]

I have opened up to begin research, documentation and produce repair possibilities for JTAG. At the time I was ONLY looking for JTAG interfacing though so I didn't pay any other attention. I put it back together but I'll check again when I'm done and maybe make a tear down thread with detailed pics for people to download and zoom in on.

EDIT: One good thing is that most of the internal hardware are interchangeable (flex cable assemblies and what not). I'm also going to see if the front housing w/ lcd and center button from the I9100 swaps over to it to allow use with I9100 roms. I know the ROM's load and run fine they just don't have the correct button mapping obviously. I personally like my i9100 much better with the center button than the i777...

Read the OP. You pic whatever one you want. I've included 3 in the base package but literally you can put whatever you want to name logo.jpg in the folder you run the batch script from. I advise less than 100KB in size although that's been dis-proven in the past anyhow.

 

[hkeyman]

No-Go...

I have tried three times and no go...I am getting everything to work perfectly but no image is producing. I have tried one of your logos and got the same results. Following the OP to the 'T' (I know you have heard that all to often...But this time its true) I'm not getting any error or failings to occur. Image is copying to the sdcard root but it seems its not passing it to the blank .lfs portion of the phone.

Is the file for the logo supposed to be logo.jpg or logo_att.jpg? Here is the excerpt from your script.

echo Preparing to copy new boot screen...
adb shell su -c "busybox cp -r /mnt/sdcard/logo.jpg /mnt/.lfs/logo_att.jpg"
