Please help me to Bypass remove activation unlock in iphone 5s
You can use CheckM8 Tool to bypass Activation Lock on iPhone or iPad running on iOS 12.4 up to iOS 14.2. The software also has a free version of the Activation Lock Bypass Tool. The main difference between the free and paid version is that the free version is an untethered bypass.
Deleting iCloud activation is a serious issue. I think contacting the Apple store would be a more sensible approach. Third-party tools claim to be able to solve this problem, but it is not worth relying on.
