Battery life – Newer Android versions (4.4+) run slower and drain battery faster on the P970’s single-core 1GHz CPU.
Hardware limitations – Camera, Wi-Fi, or Bluetooth may have minor bugs in custom ROMs. Read the ROM’s “known issues” thread.
Brick risk – Flashing wrong firmware (e.g., from another model) can permanently damage the phone. Always double-check the file is for LG-P970.
No official support – You cannot “check for update” in Settings anymore.

Pros: Safe, keeps IMEI/radio intact.

Cons: Outdated OS, most modern apps don’t support Gingerbread. Update servers likely offline.

: Download and install the LG United Mobile Driver to ensure your computer recognizes the device.
