Standard firmware allows the phone to operate normally, but once the security certificate of the device is altered (common during IMEI repair), the network signal often drops. Usually, you would have to "Patch Certificate" using a professional tool like Z3X Box or Chimera every time you factory reset the phone.

Root Included: Most auto-patch files are pre-rooted (often with Magisk) because rooting is required to access the modem partition for patching.
Binary Specific: This firmware is specifically for U8 (Binary 8). You cannot flash this on U7 or lower without risks, and you certainly cannot downgrade from U9 to U8. Prerequisites Before Flashing
