How to Unbrick Cubot X30 via Fastboot Commands

In this guide, we will show you the detailed steps to unbrick your Cubot X30 device via Fastboot Commands. The devices from this Chinese OEM are scaling the heights in custom development at quite a decent rate. Be it for flashing custom ROMs or installing a custom recovery like TWRP, there’s a lot to try out. Along the same lines, you could also root your device via Magisk– by either directly flashing the Magisk ZIP via TWRP or by flashing the patched boot.img file.

Once you have obtained administrative privileges via Magisk, you will then be in a position to flash Modules, Xposed Framework, Viper4Android, Substratum Themes. However, carrying out these tweaks could prove to be risky as well. If you end up flashing an incorrect binary or flash it to an incorrect partition, then it could result in a brick or bootloop device. Well, even if that happens, you could easily unbrick your Cubot X30 device via Fastboot Commands. And in this guide, we will show you how to do just that. Follow along.
