If you are stuck on this build and the manufacturer is unresponsive, you have three options:
Search for 00017 update.zip or 9212a firmware on Chinese forums (e.g., 51CTA, Mudan Forum). Warning: Flashing unsigned firmware can brick the device.
Rating: Utilitarian
The device may power on, show the Android logo for 30 seconds, then restart repeatedly. This often occurs because the bootloader (version 00017) has a mismatched trust zone with the kernel.
