This happens when the ROM installation script checks the device model string and encounters a mismatch. Verify that your zip file corresponds explicitly to the Z300C, and not variant models like the Z300M (MediaTek) or Z300CL (LTE Intel).
Select > System . The first boot may take 5–10 minutes. Recommended ROMs and Best Practices
(it originally shipped with Android 5.0 Lollipop), it does not support Generic System Images (GSIs) Community Efforts : Most development on platforms like XDA Developers
If you are flashing an optimized stock .zip configuration or an unofficial custom image, follow these installation steps: Asus Zenpad 10 Z300c Custom Rom

Use a high-quality USB cable connected directly to a motherboard port (avoid external USB hubs). 3. Charge the Battery
Asus ZenPad 10 (Z300C) is a challenging device for custom ROM enthusiasts due to its Intel Atom x3-C3200
