Hard reset will do nothing to remedy the Asian JCV problem with US/EU device. The link to 'How to reset a Garmin device' thread was only there because you asked in your post '[Only registered and activated users can see links. ]'

You cannot simply 'edit' the splash to enable local jcv. To see a particular Asian jcv you would need to flash the corresponding fw, in your case SG/MY. Each asian jcv is encrypted differently, i.e. SG/MY device won't see TH, PH, TN etc and vice versa, but at least it won't crash and reboot like US/EU fw encountering asian jcv. The choice for you is:

1. Leave your device as US/EU fw, just use the map but don't load the SG/MY jcv (my recommendation).

2. Try to flash SG/MY fw so that you will see the local jcv. But .... don't do it unless you know what you are doing and are prepared to risk bricking it. If you use original US boot bin you should be able to flash back though. Further discussion here would be OT, so seek advice/assistance elsewhere on the forum if you want to try. Even if you are successful and local jcv works, there may be other downsides such as TTS voices not performing satisfactorily so chances are you'll not be 100% happy anyway.
