If you bought an iPhone on eBay or from another person, then you have to enter the Apple ID and password but that's exactly what we don't have access to. So, in this case, you can unlock the iCloud account by putting your phone in recovery mode or by using a third-party tool 4MeKey to bypass the Activation Lock. For this,
First, connect your iPhone to your computer via USB cable.
Then install the 4MeKey bypass tool on your computer
After the download is complete, insert a USB drive button and install the tool on a USB drive
Follow the Jailbreak tool tutorial and restart your computer
Proceed by clicking the blue buttons and follow the on-screen instructions
Now, you will be able to remove the activation lock from your Apple ID.
If you face any issues in this process, contact our support team.
