Updated Security: Custom ROMs often include the latest Android security patches long after the manufacturer has ceased official support.
Modern Features: They can bring newer Android versions (like Android 11 or even 16 via GSIs) to hardware originally stuck on older software. The Technical Hurdle: Bootloader Locking A significant challenge for
users is Vivo’s strict policy on bootloader unlocking. Unlike brands that provide official unlock codes, Vivo generally does not recommend or support third-party ROM flashing for security reasons.
Bootloader Status: To flash any custom ROM, the bootloader must be unlocked. This usually requires third-party tools or exploit-based methods, as Vivo does not provide an official toggle for "OEM Unlocking" that works as easily as on Pixel or OnePlus devices.

Flashing: Using the recovery to "wipe" the system and "flash" the custom ROM zip file or GSI image. In conclusion, while the XDA Developers is the primary hub for device
