Give it a go, then come back here and tell us when you get the "this action cannot be processed right now" AKA "please stop creating spam accounts ffs we know" message. Honestly do give it a try and see if you can only change IMEI, if you only have to do that it makes it easier.
As I've only used my method and had success, and have failed when only changing a couple of things, I'm not sure. Testing is good
Just to let everyone know, you could definitely click one thing on your old account from your new account, but if people did this it would collapse our earning and the CPA network so fast. It's also a great way to get banned by your CPA network fast. So don't. I should delete this before idiots do it. Just y'all pretend you never read this.
