how to get my datas and whatsapp messages when disabled of my iphone 6s plus

I am understanding that your iPhone 6s Plus has been disabled and that you are looking to salvage the data including WhatsApp messages. You will have to reset the passcode with the use of a computer. The process will erase all data from your iPhone. Once the resetting is complete then you can restore your iPhone 6s Plus from a backup file that you may have created either on iCloud or on your Computer. If you do not have a backup file then you will not be able to save any data. This is the only way and see below for instructions.

You can reset your passcode by following the instructions in this article by Apple ➔ How to reset your passcode on a disabled iPhone. You will need a computer for this task and all your data on your iPhone will be wiped clean in the process.

If you have a backup created then you can ➔ Restore Your iPhone from that backup file. If you do not have a backup file created then you will lose all your data on the iPhone.

 If Photos, Messages and Contacts are synced to iCloud then you will be able to retrieve them after setting up iCloud on your iPhone after you reset the passcode and sign into iCloud.
