Custom boot animation for Motorola bravo

For those of you who are fed up with AT&T original boot animation
and want to bring a little touch of originality to your phones;
I will give you the tools to do so and then i would like this topic
to be the display of all the talent behind your idea's. Dont be affraid
to post your creations here
So lets get started.
In order to change the bootanimation on android phone you need first to be ROOTED.
that will help you in the futur with you phone anyway... but will also give you access
to root files on your phone.
Now!!!
The file that has the bootanimation data is:
system/media/bootanimation.zip
and it is formed of 4 or less items inside.
folder : part0
folder : part1
folder : part2
.txt : desc.txt
the mechanism behind these files is simple.
the 3 folders have inside of them PNG image sequences that creates the animation.
and the .TXT "desc.txt" is the script that puts it all together.
* You will notice that inside the :
system/media directory there is an audio folder as well.
This is where the sound associated to the bootanimation is stored
originally called :
boot_att.ogg or anything else the carrier wants to call it... (we'll talk about it later)
OK. If you were Able to follow sofar you must have an idea of what is next.
the idea is to replace that bootanimation.zip file and that boot_att.ogg sound to
change the bootanimation to your own.
I highly recommand to backup these existing files just in case you want to put the
phone back to it's original state...
This is where it is getting fun!
"HOW TO CREATE ANOTHER bootanimation.zip?"
sofar the best result would be obtained by creating a flash animation
of your own using adobe flash software. The screen size to select when
creating file should be in pixel the size of your android phone listed on the specs . final file will be then
published as .SWF
Once you have your SWF file you need to convert it to a PNG animation.
(what is a PNG animation?) well it is a sequence of PNG images that are put one after the other to create an animation just like the one on part0 folder of bootanimation.zip
There is a cool software that makes that convertion. It
breaks your SWF animation to a frame by frame PNG sequence.
ADShareit SWF to Video Converter Pro v5.3.zip (attached below)
....shhhhhh!!! yes i gave you a cracked one.
so when you add your SWF movie onto ADShareit you go to settings:
-Export type: Image sequence
- Sequence : Normal sequence (interact)
... the rest will pretty much adjust to the original swf file specs.
since the convertion of your swf to PNG animated is going to create a lot of PNG images
you want to create a folder on your desktop called "part0"
and on ADShareit settings you would select that folder as Export point.
Hit OK!
and let the convertion take place.
You should have now on your destop a folder name "part0" that has your SWF movie broken into several PNG
images.
At that point you have created the main animation for your bootanimation.zip file
But since the animation should play just once and then wait for the phone to boot up, you dont want it to loop.
That is why you have to create another folder "part1" that will have inside the last image of your "part0" sequence.
and that one will loop till phone boot up.( being just one image it will feel as if movie stopped.)
so i repeat:
create another folder called "part1" on witch you copy/paste the last PNG on folder "part0" you just created.
so now you have two folders:
"part0" main animation.
"part1" animation ending loop.
That's it for the animation part!
NOW THE DESC.TXT .
is just a basic txt doc on witch you type what will become the "action script"
of your bootanimation.
here is what you type: "this was when i was creating it for a motorola bravo"
480 854 30
p 1 3 part0
s loading.mp3
p 0 0 part1
now let me explain what it stands for
-first line: is the size of your animation : 480 by 854 (motorola bravo screen resolution)
then "30" stands for the speed of your animation .(30 frames per seconds/fps)
- second line part 1 of 3 (meaning first part to play) is "part0"
- third line is the sound that will play with the animation
* i said i'd talk about this later.
so here it is:
The sound format does not have to be in .ogg only it can be .mp3 or any other format your phone
recognize. the name of it also can be anything as long you use the same name for the sound file
you want to add.
(note that in front of sound line you have a "s" , and not a "p" it stands for "sound".
- fourth and last line is always the loop image file (that will be the last thing played and it will loop)
p 0 0 part1 (part1 is to be played as last.)
save .txt created as desc.txt
We have all the files now created . we need to zip:
- part0
- part1
- desc.txt
But this is not zipped just in any manner ...
you need to use 7Z compression software from there:
http://www.7-zip.org/download.html
and zip by adding to archive and setting compression to :
-achive format : ZIP
- Compression level : store
or else it will not work if compressed any other way !!!
save compressed file as bootanimation.zip
here you go.
You have now:
- bootanimation.zip
- loading.mp3
copy both to your phone SD card. and push bootanimation.zip to :
system/media
and loading.mp3 to:
system/media/audio.
reboot phone and enjoy!
I.E: I am adding my bootanimation below along with sound that goes with it.
It was too big to attach on XDADev.
so i give you mediafire download links.
bootanimation.zip
loading.mp3

Ahhhh. Thank you for this. Going to give it a go when I get off work.

Thank you I hated the stock one!
Now I have a nice Android Scribble boot

Thanks for the tut, I'll try to make my own on wednesday since I have no school. In the mean time, does anyone mind uploading one they've made?

Yes jared152,
I 've updated my post, and added my bootanimation and sound that goes with it .
I'd appreciate you giving it a try. Would be curious to see your creation!
Have fun.

lecelui, Very nice job on your instructions and explanations! It got me thinking about how much I hated the AT&T woosh boot and then the dropping globe. I'm a novice at android programming altho I have got my phone rooted and bloatware frozen. I found an app called root tools by JRummy in the market and he has included some boot animations that are clever. So now I have some dancing droids!! Hopefully 2.2 froyo will be released to everyones Bravo soon, it really speeds functions up. Thanks again for your efforts!

does anyone have the original boot animation .zip file I could get? I am really stuck the custom animation I have is keeping me from being able to update to 2.2. you can pm me or email me that would be awsome. thanks

Still kinda new to this, but:
I was able to push the animation, but the sound isnt working. Phone is not on silent when it reboots either. I'm using bandroidx's RC2 rom with Froyo, and when I tried to push into system/media, the command prompt told me it was a read-only file system. So I tried pushing into data/local and the animation was working, just without the sound. Any help would be appreciated, as I would like to make my own custom animations with sound.

There's a way to mount /system as rw in adb, but I don't know it. Do you have cwm? You can easily mount /system in cwm recovery and then push the file there I think.

I have bandroidx's bootstrapper CWM from when I flashed the ROM, and found the mount /system option, do I simply just mount it and push to the aforementioned directory with adb while in CWM? As I said, I'm still rather new to android filesystems and I don't want to do anything to brick my phone. Thanks for the patience and any help you can provide.

Yea, make sure the USB cable is plugged in when cwm recovery turns on, mount /system in the cwm menu, then push the files to where the tutorial tells you.
And if you do somehow brick, there's always an sbf.

Maybe, the boot animation for that might be in /data/local/ so either delete that file and put your boot animation in /system/media/ or just overwrite the file in /data/local

Can I install the stock boot animation?

Hey Guys,
I installed SmoothROM and that took away the stock boot animation. Is there anyway I can download and install the stock "X" animation on my Nexus 7?
Thanks

Download the stock bootanimation.zip (make sure that it is called bootanimation.zip, if not, rename it) and paste it into /system/media. delete the other bootanimation.zip that is there. reboot and enjoy.

ROM Toolbox has tons of boot animations. I'm pretty sure it has the stock one.

I also prefer the original Nexus 7 boot animation; here is my copy.
Replacing the boot animation is pretty straight forward, using a ROOT capable file manager.
I use X-plore File Manager for making such minor modifications to /system.
----------------------
First, set the file managers settings to Superuser + Mount Writable (or something similar, dependent on file manager).
Next, locate (in /system/media) and delete (or backup) your current bootanimation.zip... and then copy the Nexus 7's stock bootanimation.zip into the same place.
Once done, set the file permissions accordingly (to 644).
In X-Plore File Manager this is done by LONG PRESSING on the file in question, selecting the permissions option from the context menu that appears... and then checking some tick boxes - see screenshot for details.
-----------------------
Although the above is a relatively easy and straightforward procedure, I strongly advise, before doing anything...
*** MAKE A NANDROID BACKUP FIRST ***
If you should make some mistake with this procedure, then your device could potentially become unbootable into the Android OS (known as a 'soft brick').
But if you have a NANDROID backup to fall back on, and in the unfortunate eventuality of such a 'softbrick'... it's a relatively simple matter to restore back to your current 'status quo'.
Good luck.
Rgrds,
Ged.

I don't think the Nexus 7 bootanimation will work for Nexus 10. Does anyone have the Nexus 10 one?

Change lock screen pics on Kindle Fire HDX

Hey everyone,
I recently upgraded from the original Fire to the HDX. I searched high and low on how to change the lock screen pics on the HDX and turned up nothing. However, I did find a different way to change the lock screen on the original Fire and thought it might work on the HDX. After rooting, safe strapping, making a system back up and several hours of searching for the lockscreen pics folder, IT WORKED!! I apologize if this has already been done on the HDX but I wanted to share for those of you who couldn't find it either. I urge you to follow these steps EXACTLY or you could end up with a very expensive door stop.
**Before Starting** Your HDX must be rooted. I would highly advise installing safe strap and making a backup of your system (I boot looped twice before I finally got it right!) Down load 7-zip and install on your PC. Download root explorer from the Amazon market. Credit goes to Josepho1997 for posting this on the original Kindle Fire. I just took his method and tweaked it for the HDX.
1. Using Root Explorer from the Amazon Market, go to: /system/framework and copy (do not move!) framework-res.apk to your SD card.
2. Plug your Kindle into the computer and move the framework-res.apk (from SD card) to your computer and make a back up copy.
3. Use 7-Zip to open the one you intend to modify
4. Open the "res" folder then the "raw-xhdpi" folder.
5. You'll find 22 jpeg images in this folder, 11 images with the "_p_" in the file name.
6. Replace the "_p_" jpegs with the images you want, keeping the names exactly as they are. DO NOT delete any images. You can use 11 different images or the same one over and over again. I highly recommend formatting each picture to 1600x2650 like the originals.
7. Close 7-Zip and the new framework-res.apk will be saved, move this back to your SD card.
8. Open Root Explorer.
9. Copy the framework-res.apk to /system.
10. Long press on the framework-res.apk file and change the permissions to rw-r-r. (This is critical, failure to do this will cause a bootloop)
11. Move framework-res.apk to /system/framework. Overwrite the existing file.
12. The Kindle will automatically reboot and your new wallpapers will appear on the lock screen.
That's it! Good luck :good:

This is awesome! I think I may wait though if you suggest safestrap. It's currently not available for the 8.9.
Sent from my KFAPWI using xda premium

I don't blame you. There is nothing worse than that pucker factor you get when you go into boot loop without a backup. Hopefully, our awesome devs will safe strap your sweet 8.9" machine in no time!

I've only just got mine Kindle Fire HDX 7 to use Google Apps. Playing around with the rest of Amazons interesting design choices is the next step. This looks like a brilliant idea! Time to get my HD space pictures in there.
Thanks!
--- I have just tried this. I can copy the file to a visible directory but then i cant see it in there...
It isn't hidden or anything, thoughts?

There is a check box in Root Explorer preferences that enables you to see hidden files. Make sure this is checked first and then copy the file to the root of your SD card. You should be able to see it.

It's showing up now.
Thanks!

Sweet:fingers-crossed:

Because I am pure awesome, I managed to bootloop it too haha.
I have recovered it though and had another go with much better result haha
For anyone else having a go at this, I can't stress enough cthebadge's point about moving it to "/system" first, changing the permissions, and THEN moving it to "/system/framework"!

My next step is trying to find the gray background pic on the carousel screen. If anyone finds this before me, I'd appreciate the location. I don't see why we couldn't customize this background image as well..?

the lock screen pics doesn't bother me ,but I want to make the nova ;auncher show it's wallpaper.

How to change Kindle Fire HDX carousel wallpaper
ONYXis, you are awesome my friend!
Anyone that would like to change their carousel screen wallpaper, it's basically the same steps as I listed above for changing your lock screen wallpaper, only the pics are in different directories.
Following ONYXis's path, you want to copy the Launcher-released-signed_xxxxxxx.apk from the system/app directory and move it to your SD card. Transfer to the PC and open with 7-zip. Open the res folder and locate the portrait picture in the "drawable-sw600dp-xhdpi" folder named "home_bg.png". The landscape picture is in the "drawable-sw600dp-land-xhdpi" folder listed as "home_bg.png". Take both pics and replace them with the ones of your choice. The resolution for the portrait pic is 1200x1869 and the landscape pic is 1920x1149. **Make sure you save your new pics as .PNG and not .JPEG. Overwrite the old stock pics with your new pics keeping the name exactly the same. Close 7-zip and transfer the .apk file back to your SD card. Move the file to /system and change permissions again to rw-r-r. Move the .apk file to the /system/app directory and overwrite the original .apk file. Your Kindle will reboot on it's own and the new wallpaper appears! Thanks again to ONYXis for finding the pics!

Thanks. BTW this TUT http://forum.xda-developers.com/showthread.php?t=2373563 works too.
Notice that new resolution for HDX is 562x562 and 198x198.
My screens http://imgur.com/a/g559a and some icons from me attached (put folder "images" from archive to system/vendor/data with overwrite and reboot).

Hi,
I've mistakenly skipped step 10 and done step 11 , now, as you've anticpated, my Kindle Fire HDX 8.9 has gone into bootloop at the Kindle Fire logo. Can you help? Many thanks!

You are a braver person than I for trying this hack without safe strap my friend. The have been searching for a fix for your 8.9" boot loop and could find nothing. I am by no means a developer and will only experiment with things if I have safe strap installed. I would recommend posting your question in it's own thread and hope that someone can help. Sorry

Is it really that bad? Thanks for your suggestion anyway. I've post it in other thread already. Have my fingers crossed:fingers-crossed:

Well..it's not good! Lol Normally, I won't even attempt root without a fxz or sbf file to flash in case I boot loop. You just changed a system file when you dropped that file in the framework folder. The only way that I can think to fix it would be to somehow be able to access that file via computer and overwrite your modified file with the stock file. You did make a backup of the original file I assume..?

I followed the directions except I don't know how to "replace" the images in the file without deleting the old image files. I used the same file names for my images and copied my new images into the file after deleting the old image files.
When I moved the .apk into /system/framework several programs shutdown and I thought the tablet was going to reboot but it never rebooted. Eventually I just used the power button and shut it off. When I restarted the system all I got was the grey screen. I shut down by holding the power button for about 10 seconds and then tried a second time.... no joy.
Since I am using safestrap I am up and running, I will rebuild my rom-slot1 from backup. Curious what I may have done wrong or if I am missing some small step...
HDX 8.9 rooted, modified so google playstore works.
The _p_ files are portrait, the _l_ files are the same picture in landscape. I will figure out what the dimensions are for the landscape files and reformat all the pics for a retry.... all are 1600 x 2560 (not 2650!)
Ok, replaced all the _p_ and _l_ files, make sure they are the right dimensions and in portrait or landscape shape. It all worked and now I just need to kill the Amazon advertising.

change boot animation xdauto 1.6.2c

Hi,
is there a way to change the boot animation in xdauto 1.6.2c ? I would like to see my Chrysler car logo animation.
Thanks in advance

any luck with that yet? been thinking of changing the boot animation too.

Well, I have gone through a series of trial and error, and have successfully gotten my own created boot animation to work. However, I havent figured out the max resolution I can use (my animation looks to small from the one I originally created. Using xdAuto, the current boot animation resolution is at 480x292. Anything bigger than that, causes a black screen during the boot process (or at least this is what I've led myself to believe, if anyone finds anything different please update let us know.) Although I was under the assumption that I could use 1024x600 but my animation won't work if I use this big of a resolution.
It goes basically like this:
1. on your computer - Create a new folder and rename it to bootanimation
2. Create a folder inside bootanimation called part0 (you can add more parts if you wish increasing by increments of 1. part1, part2, part3, etc.)
3. in the part0 folder, make sure all images are in the same format. I used .png format, and make sure the pictures are in order, eg. 00000.png, 00001.png, 00002.png, etc. (You are essentially making a slideshow that plays at a max of 30 frames per second)
4. Install "boot animation creator." You can google for this or search for it here on XDA. (I cant post urls yet.)
5. open boot animation creator, follow the prompts to make your boot file, don't forget to add a loop when that section comes up for making your bootanimation.zip file.
6. place your bootanimation.zip file in your android HU (I'm using a carpad III).
7. (root required) go to the root of your Android HU/carpad. Go to this path /system/media
8. make a backup copy of the current bootanimation.zip file and place it in a safe place.
9. copy and paste your created bootanimation.zip file in /system/media
10. reboot, if done correctly you should see your new bootanimation.
Hope this helps.
Update: So my main problem, was that root browser was giving me a "operation failed" error. Its strange because sometimes it would let me write to the /system/media
folder. I was able to get a 819x432 bootanimation.zip to write. But now for some reason I can't get anything else to write to it... very strange. I am pretty sure that the max resolution for bootanimation.zip for Carpad II / III is 1024x600, getting it to write when I want it to is the issue I am having now.

Okay, well I found out why I was getting the write errors. Well, at least this worked for me.
I went into SuperSU, settings, and unchecked Mount namespace sepraration.
This allowed me to write my bootanimation.zip file to the /system/media/ folder.
I was also able to use my original 1024x600 bootanimation.
Hope this helps.

Possible to change leanback home background from the green blood cell wallpaper?

Hi, I recently bought a 2017 shield and Im now running the latest Android TV but to my dismay I haven't been able to figure out how to change the background from the, in my opinion, tacky wallpaper of the green blood cells? Is this possible at this time?

This is not my work but here you go:
Anyone interested in a tutorial on how to change the default wallpaper on your Nvidia Shield TV? (And possibly Android TV in general, have to figure that out first)
Root required..
Step 1: Edit your own wallpaper image so that it is named nv_wallpaper.png with dimensions of 1920x1080. Don't just rename a jpg to png, convert it.
Step 2: Back-up the NvCustomize.apk file in the /system/priv-app/NvCustomize/ folder to a secure location. Or use a backup tool.
(Note that when you copy the file back, the permissions have changed and you need to change them back to chmod 644 (for the apk) and chmod 755 (for the folders, which you don't need to backup per se)
Step 3: Copy a second version of the NvCustmize.apk to a location you can access on your PC or an easy to remember location you can access with a file explorer. Not all file explorers let you write to the apk when it's still in the system folder. So copy it anywhere else.
Step 4: Somehow merge the new PNG you made with the NvCustomize.apk, without decompiling or extracting the apk. You can use Winrar, but DON'T extract it. leave the file intact and just copy the nv_wallpaper.png to the location of the same png in the file and overwrite it. Done.
You can also do this on the device itself, with some effort. I use X-Plore for that (in the ATV Play store). To open the file as a zip and copy the png inside that apk.
the correct folder inside the APK is: NvCustomize.apk/res/drawable-xhdpi-v4/
put the file there (within winrar or the file explorer on the device) and overwrite.
Step 5: Copy the modified NvCustomize.apk back to the /system/priv-app/NvCustomize/ folder and overwrite it.
Step 6: Check the permissions of that file. In X-plore you can long press the apk, scroll down and select permissions. There you must see 644 in the bottom right. Or all Read checked and one write (owner) checked. Owner should be root.
Step 7: Reboot!
Done.
Hope that helps!

Thanks, that certainly does help, but heavens is that convoluted for such a seemingly simple request.
