Technical questions, ROMs
The EU ROM is a ROM created by a community of independent developers in collaboration with Xiaomi. This ROM is multilingual and equipped with the Playstore. We install it. on devices imported from China that were originally equipped with a Chinese ROM. Updates are done either by computer or by TWRP recovery software. A device equipped with this ROM requires a little technical knowledge. We will provide you with the necessary support but do not recommend it to inexperienced users.
The Global ROM is the ROM developed by Xiaomi for these devices intended for the international market. It does not require any special knowledge from the end user.
