This wiki will consist of explaining how to elaborate about every single proccess known for Lenovo z5s (also known as Jd2019-L78071) and providing the tools and links that might be needed for them. will begin for the basics as how to unlock bootloader to how to fix the most of the severe problems as very deep brick phone. Will also include shortcuts for every single section of this guide to avoid any annoyances of looking for specifics during any proccess
I'd recommend that you already have a little of knowledge of what is, and what is for things like platform tools (adb minimal tools, fastboot tools etc etc... are all the same with the difference platform tools are the most updated and less jaggy), bootloader (fastboot), recovery and how to use CMD, also i would like to clarify this is not a guide for developers, maybe later at some point a developers section might be included for the wiki, but as it is for now this guide is for those who wanna install and test roms, and wanna fixed some common issues the phone might have during flashing and installing any related recovery software
