Advanced Settings: You gain access to hidden menus, such as manual band selection, TTL fixation (often used to bypass tethering limits), and IMEI management.
Security & Stability: Universal updates include the latest security patches to protect against vulnerabilities. Where to Download Huawei B315s-22 Firmware
