You don't have to boot into recovery mode if you have root explorer installed. In root explorer you have to mount R/W first then rename it.
[After applying R2D2-bootanimationmod.zip, you can easily disable the boot animation sound by renaming /system/media/d2_r2d2_pu.ogg to something else, like d2_r2d2_pu.ogg.bak. Then, re-enabling it is as simple as renaming the file back to its original name.]
