With some helpful advice from these forums, I was able to replace the China Unicom boot animation from my Xperia ZL with a stock version. FYI, this was located in /system/media on my phone.
However, I still have the China Unicom shutdown animation playing on shutdown. Any ideas on where this might be, and how to remove/replace it?
Please help me get this annoying Chinese branding off my phone. I would sincerely appreciate it.
