[Optimus One, P500, V Q&A, Help & Troubleshooting] HardLight:
Already tried this earlier, but I done this again.

Decompiled SystemUI.apk, SettingsProvider.apk, Settings.apk, framework-res.apk and looked into their bools.xml (found 9 of them).

Yes, there are many settings, but nothing about language.
