Many Android users unlocked their bootloader and install custom recovery on their device only to install custom ROMs. No doubt custom ROMs are one of the best things about the Android ecosystem but there are some major drawbacks too. Custom ROMs are developed by third-party developers so there is a huge possibility of not getting regular updates and support for the ROM. Only popular ROMs like Lineage OS, Pixel Experience and Carbon get official support from their respective team. With time Custom ROMs do make the device slow as they are not optimized properly. Some times users experience various bugs while using a Custom ROM. And the biggest issue is bricking the device. While the installation process of Custom ROM is fairly simple but there is a huge chance of doing something wrong and bricking the device. In that case, only installing or flashing back the Stock Firmware can fix the device. [su_box title=”Vivo X20 Stock ROM Details:” box_color=”#004cf2″ title_color=”#ffffff” radius=”2″]
