[Nexus 7 Android Development] Balian67:
I get the error message: "failed to copy 'bootanimation.zip' to 'system/media/bootanimation.zip': Read only File System". I checked in root explorer and it is mounted as R/W.

Another question. I have made several Doctor Who Boot Animations for the HTC EVO 4G (original) and so I have done boot animations. However for some reason I have never been able to get my bootanimations to work Since like CM 7.2.

When looking into the actual bootanimation.zip the desc file is exactly alike.

The bootanimation you have in the root of your zipped directory has this desc information:

" 700 700 20

p 1 30 android

p 0 0 ATT "

I know the 700 700 is the res at which the phone should display the images in said "android" and "ATT" folders. I also know that 20 is the framerate at which it should play. I also know that p 1 means play once (if I remember right), but what is the 30? (how many times to play that picture before moving to the second folder I am assuming). Then of course P 0 0 means loop until it boots. FROM my experience it didn't matter what you named the folders as long as you have that in the desc.txt file.

My desc file consists of this:

1280 720 30

p 1 0 part0

p 0 0 part1

I have a part0 and a part1 folder each with images in it. EACH consisting of boot_0001..etc (in numerical order). Yet I can't get it to work. It flickers but the screen stays black. I am almost wondering if I have to change some other file to make it work with CM. Any ideas? For the record I copied and pasted my bootanimation.zip from the internal memory to /system/media using Root Explorer. I also tried changing the desc.txt file to 700 700 20 just for the hell of it and it is still black screen. I haven't had good luck at all with the newer CMs I maybe have tried it with Sense as well. I should try it. I would also like to find out if for some reason there is a size limit now in the newer android versions. This bootanimation.zip is 21 mbs. So let me know!

settings > Developer Options > Root Access = ADB and Apps. (Android Debugging was already on)

cmd > cd blah (to your directory) <enter>

adb root

adb remount (remount successful)

Ran your bootanimation changer .bat and it was successful flashing (copying) my bootanimation.zip to the system.

Reboot

Still black screen

So I have to assume my bootanimation is whats wrong. I am going to try 1 more thing (before saving this).

I found a boot animation creator on xda. I have been using that. NOW I have some images but it wont move to part 1 folder. This thing is getting REAL frustrating. I am playing with resolutions as well. Find a resolution I like for this tablet/images.

I got it working by just having p 1 0 part 0 then have all my images in that. It isn't long enough to last the whole boot time even if I lower the frame rate to 20. I have over 300 images sized at 1280x720. Which btw the working boot animation I have now is set to 1024 720. I know this post is very bipolar in the sense I ask for help then sorta answer my own crap...but hey. Maybe someone can read all this and know exactly what to do lol.
