Tablet bootlooped because of bootanimation.zip ~ No TWRP/CWM support So I installed a bootanimation on my tablet and it bootlooped because the bootanimation basically crashes the boot sequence

So can I somehow delete bootanimation.zip file? I tried fastboot erase system/media/bootanimation.zip and it says RESULT: FAIL(unable to format) 
Any help is appreciated
Use this temp bootloader to sideload twrp from a PC via fastboot. Can confirm this will work with K013!
Get an SD card format it too EXT2, not anything else. Then use the link below. Now u can back up and thusly manipulate your system partition thru twrp or pull a backup via sdcard and do some magic on the pc with the resulting zip file, repack it ans load the backup.  Either way this intel temp recovery thing works on K013 with 4.4.3 kitkat. All the custom recovery that can be actually put on the device require update to 5.0 lolly and above, as this reformats the hidden boot partitions Asus used...the boot is nit normal. Finnally bootanim.zip must be set to be the exact screen resolution the device expects. Can't use just any.
