Stock Firmware vs. Custom ROM: What You Need to Know

For the China Mobile A4s, there are virtually no stable custom ROMs (like LineageOS). Therefore, Stock Firmware is your only reliable choice. The Ultimate Guide to China Mobile A4s Firmware:

• Stock Firmware (Official): Stable, safe, retains warranty. Includes China Mobile bloatware.
• Custom ROM: Not recommended. Due to the Spreadtrun/Unisoc chipset, development is minimal, and you risk bricking the device permanently.
