Jesty Thor Fix
A free, open-source utility that truly powers off the Thor's bottom display, stops AYN Dashboard from pinning CPU clocks, and shows live CPU/display telemetry.
Description
Jesty Thor Fix addresses two separate AYN Thor firmware problems. First, Top Only mode can leave the lower display looking black while its physical display hardware is still active — the display controller stays on and can even come back after wake. Second, the AYN Dashboard can leave LITTLE/BIG CPU cores pinned at maximum clocks instead of letting them scale down at low load, which wastes power and produces extra heat. The same pinned-core behavior can also appear when using apps in single-screen mode through AYN's own implementation. The app is free and open source, and requires no accounts, credentials or cloud services.
What it fixes
The app provides two independent switches, because the Thor has two different problems:
- True Bottom Display Fix — in TOP mode it powers down the lower display hardware; after sleep or wake it checks and restores true-off if Android reactivated it; in BOTH or BOTTOM mode it leaves the lower display available normally. It never chooses a display mode for you.
- AYN Dashboard CPU Fix — stops CPU cores from staying pinned at maximum clocks while the AYN Dashboard is open, and also fixes the same pinned-core behavior when using apps in single-screen mode through AYN's own implementation.
Which switches should you use? If you use TOP mode and want the lower display truly powered off, enable True Bottom Display Fix. If you use the AYN Dashboard or regularly use both screens, enable AYN Dashboard CPU Fix. If you switch between TOP and BOTH, enable both fixes. Your choices are saved and restored after a normal reboot.
The app also shows live telemetry — the current display mode, CPU clocks and a live power estimate — so you can see both fixes working.
Setup guide
Download and install the latest release (v1.3.0). No Magisk, no terminal and no rooting are required. Open the app once, enable the fix or fixes you need, then close it — the fixes keep working in the background. Use Check now to verify the current display and CPU state. Note that enabling or changing the AYN Dashboard CPU Fix restarts the Android framework once and closes open apps; the displays stay black briefly while Android returns.
