If the system freezes on the boot logo, you must perform a hard flash. Connect the stereo to a laptop via a USB data cable and flash the original scatter file using SP Flash Tool .
The Cortex-A7 is an efficient core, but the T3 P1’s original firmware had an overly aggressive thermal governor. Under moderate load (e.g., GPS navigation + music streaming), the CPU would throttle down to 480 MHz unnecessarily. The new update recalibrates the temperature trip points, allowing sustained performance at 1.0 GHz without triggering emergency throttle.
The T3 chip often struggles with modern, RAM-heavy apps like Google Maps or Spotify running simultaneously. The P1 update introduces aggressive background process mitigation. This ensures your active navigation application does not crash when a notification arrives. 2. Audio Processing Patches Quad-core T3 P1 Update
