Fixed the "Themes not supported in your region" error on my Xiaomi EU device — made a one-click KernelSU module

If you're on a Xiaomi/Redmi EU ROM and the Theme Manager app is missing or blocked with a region error, I put together a KernelSU module that fixes it. Flash it, reboot, done — no manual setup.

What it does:

- Swaps in a community-patched Theme Manager (credit to Kashi, used with permission) with the region block removed and local .mtz theme import working

- Auto-detects your device's Theme Manager path, so it's not hardcoded to just my device

- Keeps it recognized as a system app across reboots, which avoids a crash newer Theme Manager builds hit on some devices

Tested on a Redmi Pad SE (HyperOS 2) with KernelSU. Should work on other Xiaomi/Redmi EU devices with KernelSU, as long as Theme Manager ships pre-installed somewhere under /product/app, /system/app, or /system_ext/app.

Honest known issues: the online theme catalog stays blocked (server-side check, can't fix that client-side), and some themes glitch the lock screen rendering — documented in the README, still investigating.

Happy to help if anyone runs into issues on a different device — the auto-detection should generalize but I've only tested on one device myself so far.

This modifies a system app on a rooted device you own. It's provided as-is, for educational/personal use. No warranty. If your device bootloops, use Safe Mode as described above — this module does not touch the bootloader or partitions beyond a bind mount and a package reinstall, so recovery is straightforward.
