A: No. The V12 version is specifically compiled for ZQ03 hardware revision 1.2. Flashing on V14 may break the touch controller.

A: Absolutely. As long as you have the original stock image from the manufacturer, you can flash back using the same SD card method.

That said, the installation process carries inherent risk. If you are uncomfortable with bootloaders, MD5 checksums, and the possibility of a brick, hire an experienced technician or stick to the stock firmware.

Backup your current system, read the original forum thread at least twice, and flash with confidence. The V12 repack is worth it. Have you installed the ZQ03V12 Repack on your device?
