[Sprint HTC EVO 4G LTE] neutopian:
So I wanted an appropriately shiny boot animation for my newly Fresh-rommed Evo, and I found this page:

http://droidmodderx.com/galaxynexus/how-to-install-100s-of-bootanimations-for-your-galaxy-nexus (Full of previews, will bog your computer down!)

That phone has the same screen resolution, 720 x 1280, so most of these seem to work for me. I didn't bother with flashing them from recovery, as the bootanimation.zip file can be easily extracted and placed in /system/media using Root Explorer. Your mileage may vary. I am using Spyro at the moment, nice ICS-ish colors.

SOME of them did not work, or rather they worked, with intermittent flashes of a white screen..I am not sure but suspect it's something to do with frame rate? Anyone?

Updates.................

Directories: Your individual rom maker may have put the animation package in one of several locations. These include:

/system/media

/system/customize/resource

/data/local

I have seen still other locations used on my old EVO 4G (and new roms are coming out all the time), so if you just cannot find anything, try doing a search for 'animation.zip' from the root level, with your file browser.

Filenames: Your rom maker may have used one of several slightly different name variants for the bootanimation.zip package; it really depends on what they started out with as a base. Sense-based roms, for example, will tend to change things up. You might have an 'HTC_bootup_one.zip' instead of a 'bootanimation.zip'. You can't go wrong by naming your new package the exact same thing, and putting it in the same folder. (BUT you also have the option of deleting all oddly named animation packages you find in odd locations on your phone, and just using the standard 'bootanimation.zip' and putting it in /system/media. This is the Android standard location, and it will almost certainly look there if it can't find it elsewhere. Note that if you do this and fail to find and delete the other package, it will still use the other instead.)

Permissions: You shouldn't need to change permissions on the package file, at least that's never been an issue for me. If you are having problems there, I'd suggest trying the standard 644 setting one usually finds in the system folder, or RW-R--R--. (As long as the file is Readable by the owner, I would think that it would work.)

I can't delete or change these files! You may be using ES File Explorer, which is not the easiest app to drive. It requires root permission being set in its settings, and if you don't do that, hilarity can ensue. (I again recommend Root Explorer by Speed Software, which is not free but gives the most straightforward file browsing experience you can imagine, a big plus if you're new to rummaging around in your phone's innards!)

You absolutely cannot play with this stuff without root, so don't even try, okay? And when you want to change anything in a root-level folder, you will need to remember to set that folder RW (read/write), and then remember to set it back to RO (read only) when you are done, yes? You smart folks already know these things, I just want to make this post as complete as possible.

But I need MORE animations! I found the link above by googling 'bootanimation.zip 720x1280' so have at it!

If you've any more questions, please ask..
