Because it doesn't work the same for all the countries, the drone gets it's location and applies certain parameters to the firmware/fly app, like for example after certain version in Europe you could no longer enable the bottom light manually (which you can now with the hacked firmware), but you could still do so in US, with the same firmware/fly app version.
RID requirements on Europe and US are similar, but not the same, so the hack may only apply to the Europe version.
Unless someone leaks the 1001 .45 version, that apparently can remove RID on US too, that's basically what we have. I've not seen any other working hack around to remove RID/Aeroscope, as the Jeepdoors one is quite obsolet and only works on old drones with old fly app versions, like the
Mini 2 for example.
