Upgrading a device from Android 4.4.4 (KitKat) Android 5.0 (Lollipop)

• Bricking the device – If the ROM is corrupted or incompatible, the phone may become a non‑functional “brick.”
• Security vulnerabilities – Unlike official updates, custom ROMs may not receive security patches. Some “patched” files have been known to include malware or spyware.
• Loss of features – Hardware like the camera, Wi‑Fi, Bluetooth, or GPS may not work correctly because proper drivers are missing.
• No support – If something goes wrong, there is no manufacturer or Google support to help.
