Having a smartphone can mean two things in general, keep it with the Android system that comes from the factory (ROM Stock) or choose to install one on our own (Custom ROM) as long as there is development for our mobile in question, something that we can find out in XDA Developers. It is almost a norm or development synonym to have a terminal that has a processor Qualcomm Snapdragon, since the American company usually releases easily the controllers of its SoCs, something essentially vital for developers.
But not only the drivers are required to be released but the manufacturer also releases the source code of their device, since one of the requirements of Android as Google requires manufacturers to release the source code of the devices to the community. On the other hand there are MediaTek processors, which in the majority do not usually have a good development on the part of the community due to their negative posture in the release of the controllers of their SoCs.
With this in mind, one of the main requirements to install a custom ROM is have the bootloader unlocked Y have a custom recovery installed, which in this case and for most phones is TWRP, which has practically been standardized for being very versatile and easy to use. Once this is done, we will proceed to search and choose the ROM that is most to our liking to download the ZIP file of it and at the same time download the Gapps (Google applications) from OpenGApps in your package elder brother, although you can also use the graphic installer of the package To Rome to choose which Google applications you want to install.
one.- We restart our terminal in recovery mode.
two.- Before installing any ROM, you need to clean (Wipe) some partitions. This is done by entering the section Clean.
3.- Within the section Clean we will select the option Advanced Cleaning.
4.- Once inside Advanced Cleaning, we will mark the partitions Dalvik / ART Cache, System, Data Y Cach. If we wish to clean the internal memory of our mobile, the option will also be marked Internal memory, although it is not strictly necessary but sometimes the ROMs do not usually boot until one also clears this partition, this does not always happen because it is very unlikely to happen.
5.- Once the cleaning is finished, we will return to the main menu where we will see all the options and enter Install.
6.- Within the option of Install We will choose the storage where we have previously downloaded the ZIP files of the ROM and the Gapps to proceed to select the ZIP files for the installation, remembering that the ROM is always installed first and then the Gapps. Once the files are marked, the installation of the ROM and the Gapps is carried out. If you chose the package elder brother of the Opengapps you won't have to do anything else but if you chose the package To Rome, you have to read this tutorial to learn how to use it and mark the options indicated in it to have a proper functioning of Google applications on your mobile.
Once the process is completed and finished, you just have to restart the terminal and wait for it to start. The first start always takes a long time.
