[Q] G2x boot animations and SPLASH screens, please help me

On my G2x i have CM7 and the boot goes as follows.
1.) Bland LG logo
2.) Flashy colorful LG boot animation logo
3.) CM7 boot animation with spinning arrow.
I want to change either step one or two to something different, preferably step 1, its super ugly. I despise two different LG logos in a row. Some dev please help. I cant get it right. Nobody has posted an easy solution yet.
Thanks

to do that is risky business.. you have to modify the primary and secondary bootloaders... (correct me if i'm wrong) there is a higher risk of rendering your phone unusable.. (BRICK) i will research it and see what i come up with.. if you flash eb the second bootlogo is awesome but the LG is there and you can always search bootanimation and download.... out it in system/media and reboot easy peasy....

Nope! It's a pain to do, but as far as I know it's not dangerous. The splash screen (one or both? unsure) are contained in the boot.img file that can be rewritten via flashing a zip from Clockworkmod. For instance, if you flash the Trinity kernel, it will change your splash screen (to a really, really ugly one, but that's beside the point). It involves "cpio" archives and a little bit of Linux acumen.

I don't know Linux. No apk that does it for you?
Sent from my LG-P999 using Tapatalk

No there is no apk. You are editing the initrd.gz, apk's don't have access to that part of the system.
As for the first logo, when you first turn on your phone, that's really not editable without hacking the hardware, I'd highly suggest living with it.
First logo - part of the hardware on the phone, coded in.
Second log - part of the initrd.gz (logo.rle file inside it)
Third (boot animation) is in /system/media/. It's called bootanimation.zip. (Easy one to replace.)
You'll never be able to do this without linux, windows doesn't have any kind of support for cpio archives. Plus with the way linux file permissions work, it's way too easy for you to break them when you copy them to a windows partition. The number one reason for bootloops on android is improper file permissions. (For the logo when the linux kernel is loading, logo 2 i call it.)

The first LG Logo is not part of the hardware... It's in the boot.img file. It was easily changeable on HTC Phones.

No, it was. On the hd2, for example, if you wanted to change that logo (when you first turn it on, it was the tmobile logo if you had tmobile us version) you had to flash a ruu to update that image. (Yes, it was easily done, but not so much on this phone.)
I think you're confusing the second image, (before the boot animation), which is the logo.rle file. It's in the boot.img, inside the initrd.gz. (This can be easy to confuse, especially if you're running cm7 or anything based off it, because the logo is the same, and it just flashes real quick.) If you look at the 2.3.3 based ones, there is a blank screen between logo one and the boot animation. For some reason, that logo doesn't load, and that's where the second logo would be, the one I'm referring to. (On 2.2 it was the lg logo with the semi-animated loading bar underneath it.)

Hmmm, time to throw together a shell script to make this easier for those not command-line friendly.
And if you have a Mac, this should work there as well (I assume there's cpio support, there must be). Anything Linux/UNIX.

Yup. It works on mac as well, from what I've heard. (I don't use macs much myself, I can't stand macOS. But the procedure should be quite similar.)

Well, if we can extract the boot.img using a program such as unyaffs or something like that, we can swap the images.
And there's an app in the Market called BootFlash, but it currently only works on HTC Devices. It allows HTC Users to changed their splash screens. Let's hope they add support for the G2X!

Instructions from mstrk242: http://forum.xda-developers.com/showpost.php?p=15627311&postcount=1025

The instructions from that thread assume you already know how to unpack the boot.img file and can see the initrd.gz within it. If you don't, I'd suggest starting here:
http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images
*edit*
The important parts are under the section Unpacking, Editing, and Re-Packing the images, however I'd suggest reading it all. It really gives good info, and an explanation of how it works.

Ok, I figured I'd make a super detailed howto on how to do this, so here it is:
First off, download the following file:
http://jamezelle.com/myfiles/split_bootimg.zip
Now, unzip that, it's a pearl script. (split_bootimg.pl) Copy that, and your boot.img to a directory. Type the following:
./split_bootimg.pl boot.img
This will create 2 new files in the directory, boot.img-kernel, and boot.img-ramdisk.gz. The ramdisk is what you want. Now, inside the directory you created and split the boot image, make yet another directory (I'll call it temp for the purposes of this howto)
cd temp
now, type the following:
gunzip -c ../boot.img-ramdisk.gz | cpio -i
Now, inside the directory you have successfully decompressed the ram image. (Which on my other post I refered to as initrd.gz, same thing, different phone in this case )
You'll see a bunch of files there, the one you are interested in for the init boot logo is called initlogo.rle. THIS is the file you need to edit to change the boot image to whatever you want. (If you are unsure how to do this, google rle editing, or something similar, not going to go into that here.)
After making all the changes that you want (also a useful tip, the init.rc is a very useful file as far as android booting, if you take the time to learn android's init script language you can do some cool things.), go up one directory. (cd ..)
now you should be back in the directory that has the following:
boot.img, boot.img-kernel, boot.img-ramdisk.gz, and split-bootimg.pl. I'd highly suggest copying your boot.img-ramdisk.gz that's in that directory (which is the original) to another folder, then delete it. (Otherwise you're going to overwrite it anyways). After you have done this, go back into the temp directory that has all the files you changed.
Type the following;
find . | cpio -o -H newc | gzip > ../boot.img-ramdisk.gz
This will create the boot.img-ramdisk.gz in one directory level up (It's important to do it this way, otherwise you'll end up packing a ramdisk file inside another ramdisk file).
Ok, almost there, now you just need to repack the boot.img file
To do this, you'll need mkbootimg, which i highly suggest compiling from the android repo. (Google it, again, not going into that here.)
Copy the boot.img-kernel file and the boot.img-ramdisk.gz file to another directory, so you don't pack uneeded files into the boot image. Go to that directory, and do the following:
mkbootimg --cmdline 'no_console_suspend=1 console=null' --kernel boot.img-kernel --ramdisk boot.img-ramdisk.gz -o boot.img
If you have done it correctly, you'll see a boot.img file in there. You're done. Replace this in the cwm zip, and flash.

Ok, one more little helper (because I'm in a good mood today ), here are the files you'll need. I have included bootsplit file and the mkbootimg file, so you don't have to bother compiling them (the bootsplit is the same as the link I gave in the post above, but I figured to be nice I'd pack them both into one easy zip file.) With this, no mkbootimg compiling required. (Keep in mind this is compiled for x86, since that's what I use. For x64 you'll have to compile it yourself.)
Good luck everyone.

Oh man, thank you. Ill let you know how it goes tonight.

Splash Screen

Could somebody please direct me to a tutorial or explain to me how to change the splash screen on the G2x because i was able to change my bootanimation.zip quite easily, but apparently the splash screen is a whole nother story, and really dont want to screw it up. Thanks in advanced!

What are you referring to when you say "Splash Screen"?

the screen that pops up right before the boot animation

Rom toolbox will allow you to change it alot easier then messing with system files
Sent from XDA premium G2X running CM7

It is part of the boot.img, which is what contains the kernel. You would need to extract all the files in boot.img, replace the splash and then compress it again in the correct format. Or you can compile your own kernel and change the splash screen when you make your boot.img for flashing.
People that work on custom kernels can give you more information about this than I can.

Boot logo location?

Hello, I just want to know where is the boot logo (not the boot animation) file locate in the root since I can find the boot animation in /system/media/ but I can't find the boot logo which is single image and not am animation. I just want to have an opportunity to change it to make the device virtually "fully customized." Thanks :beer:

Usually in the kernel.
EDIT:
Some devices even have separate partitions for the "splash image" or "boot image"

This might help https://forum.xda-developers.com/android/software-hacking/guide-how-to-create-custom-boot-logo-t3470473
For my EXYNOS samsung s7 edge the boot logo was in a file called PARAM under /dev/block/platform/155a0000.ufs/by-name/.
I opened the file with winrar and found the bootlogo there. Pretty sure other devices especially snapdragon variants wont be the same.
If not, try to look for a working custom bootlogo for your device, and look for update-binary in the zip and open it with a text editor you might find what you need to know there.
Hope this helps.

Change Boot animation?

So i've tried to use the bootbox app to change my boot animation, i've used itvon my old phones bu t this is 1st Samsung, what's the proper way to change it?

I'm also interested in this.

You might want to read this thread my friends ...
http://forum.xda-developers.com/showthread.php?t=2073775

So yea, the reason I rooted my phone in the first place was to hopefully be shed of that obnoxious boot animation, but it seems our phones are "unique". I've done the bootanimation.zip replacement and permissions, I've done the individual files (my media directory has both, as well as one in the bin). And I STILL get the obnoxious virgin mobile animation. I followed the link above.. and uh..whaaaaa??
I'd like to hear from anyone that has successfully changed their boot up animation to something cool on their SM-J700P.
Would going to a custom ROM work? I have hesitated since I have marshmellow at present.

I have boot animation support. Depending on the response I get back I might write a "how to" thread. Plus I have a BUNCH of boot animations. I can post the directions and Samsungani files needed.. right now my phone boots up like PlayStation

Do you have the Android default boot animation system working, or just support for the qmg system?

Got it working. Look up bootanimation4U... Flash it. If you can't find it lemme know and I'll post it

Then, manually change out your boot animations or make a flashbable zip

Help here
I accidentally deleted bootanimation.qmg file in my Galaxy j7 and after that the samsung boot up screen is not showing... I tried flashing and manual methods to fix it but nothing seems to help.

Devs please provide different boot animation flashable zips..

[GUIDE] Modify Boot Logo

Hi
I managed to modify my Bootlogo to a black one and want to share how I have done it
Do this on your own risk, I'm in no way responsible for damage you do on your device!!!
1. Backup the logo partition from your device
You can use adb or a terminal shell for this
Code:
dd if=/dev/block/bootdevice/by-name/logo of=/sdcard/logo.bin
2. copy the logo.bin to your pc or pull it via adb
3. download Motorola Bootloader Maker
4. Within the program, open the logo.bin
5. Extract the existing images to edit them if you like
6. Replace the Images you want with a modified or newly created one
I created one with the red Lenovo logo on a black backround
and saved it as a 8bit color png with a resolution of 1080x1920.
7. Save the new logo as a .bin or .zip file as you like,
I attached my flashable zip to this post.
8. If you choose zip, you have to modify the script, as the included one does not work with our device.
Change all the partition paths to /dev/block/bootdevice/....
You can use the script from the attached zip or replace the included logo.bin with yours.
Use twrp to flash the Zip.
9. If you choose .bin flash it via fastboot
Code:
fastboot flash logo logo.bin
Enjoy your new bootlogo

Ähm, I still don't get your point.
Boot animations don't need to be made for a certain device.
Just use the one from your thread if you like
Nevertheless I made one matching my boot logo.
Copy it to /system/media and modify permission to how they where set before.

Isn't the stock logo some kind of a precaution measure? The lock/unlock symbol shows whether the phone gets permission to boot. When I was experimenting with Magisk I noticed the phone wouldn't boot. It had something to do with dm-verity, but I wouldn't been able to tell that easily if I had replaced the boot logo.
Of course you only have to worry about this when you're messing with files which have an impact on verified boot.

No, it's just an indicator if the bootloader is locked or unlocked.
You can change both images independently.
If you want, just use a different one for each.

Took a look inside the Zip to see what the boot animation looks like. Great job.

Thanks a lot for this. That blinding white was really annoying.

Thanks a lot for this zip, Perfect...
That blinding white was really unbearable.
This seems to be done for an amoled.
Better than Lenovo.

Can anyone elaborate backup process?
