Rooting fixed my lag (via SmartPack-Kernel Manager and tweaking the governor to schedutil), but the phone now runs at an average of 45°C - 48°C on the CPU during light use.
Here is where it gets weird:
I suspect Motorola has a proprietary thermal engine (/vendor/etc/thermal-engine.conf) that detects root and falls back to a "safe" (but aggressive) throttle profile, or the patched boot image breaks the DVFS (Dynamic Voltage and Frequency Scaling) handshake with the MediaTek power HAL. root moto g 5g 2022 hot
Once you’ve cooled down your device, implement these long-term practices:
If you previously deleted thermal-engine.conf, download the stock file for Android 12/13 (Moto G 5G 2022) from XDA forums. Rooting fixed my lag (via SmartPack-Kernel Manager and
Steps via ADB root:
adb shell

mount -o rw,remount /vendor
cp /sdcard/thermal-engine.conf /vendor/etc/
chmod 644 /vendor/etc/thermal-engine.conf
reboot

| Problem | Solution |
|---------|----------|
| fastboot oem unlock fails | Your device is carrier-locked. Root impossible. |
| Bootloop after flashing | Flash back the original boot.img and try patching with Magisk Canary (beta). |
| No Wi-Fi after root | You flashed the wrong boot image. Match build numbers exactly. |
| Google Pay/banking apps broken | Install Magisk modules: Play Integrity Fix + Shamiko. Then enable Zygisk and DenyList. |
A: Yes. Open Magisk → Uninstall Magisk → Restore Images. This flashes your original boot image back. If you didn’t back it up, re-flash the stock firmware via Fastboot. The phone will return to normal thermal behavior.
