I really want to change the bootanimation on my Poco F1 (MIUI 11 based on android 10). However, whenever I try copy-pasting the bootanimation.zip to System(Root)/system/media/theme/cust_config/global and change the permissions to rw-r--r--, the zip file suddenly disappears. I have mounted the system to read/write. I have tried it in Mix explorer - it does work but if I were to exit out of the global file and enter back the bootanimation disappears too. Is this supposed to happen? I know I'm not supposed to ask here but I'm desperate to change the bootanimation.
