whatWhat you are trying to do is very possible, but your methods will never work. firstlyFirstly, you gottagot have to know that there are two different com.whatsappcom.whatsapp
folders. The one you were just talking about is so useless that anyone on any device can access, you it.
You need the whole directory from <root/data/data/com.whatsapp>root/data/data/com.whatsapp
. toTo copy this, you need root permissions right, and to copy them in a new device you need root as well, so that you are able to put them in the root dir.
