Customizing a Lenovo smartphone can be fun provided you know what you are doing thanks to some clear guidance and sound advice. Sometimes the hardest part is not following the guide itself but knowing whether you need to have an unlocked bootloader or not to get things under way. It’s important information that is often left out.

For what it’s worth, there are smartphones out there that do not need to have the bootloader unlocked before they can be rooted or have a custom recovery installed. We see this all the time with Samsung devices and getting rooted with the CF-Auto-Root tool. Furthermore, we see it with Samsung when people go to install TWRP Recovery.
