AT&T give me a unlock code. My phone is unlock now. If I debrand, flash, update firmware (with XS++), play around with it, would it LOCK my phone again?
Beside, what's the different between debrand and flash and update firmware with XS++? I thought that to update firmware, we flash the phone. And when we flash it, that means we debrand it.
If it's different, somebody please give me the link to the guide to flash, debrand and update firmware so I can actually know what I'm doing.
Thanks
