Changing CSC resets purchased premium

[kttjarr]

I recently changed my phone's CSC and when I tried to activate premium again using google purchase code, it would say it's an invalid code. Would changing CSC make it as if it's new device? Is there any way to fix this without reverting back to my old CSC?

Changing the CSC alone should not impact it. However cross-flashing firmware from a different region may change the device model number depending on the flashed firmware. Please email us your activation code so we can check.

Nevermind, forgot that I spoofed my device.
