A guy here posted a command,i did that and it worked.I think its a couple of pages ago...The error i was getting was -1 generic error.
This is the command i used.
go to:
"Device Manager", right-click your device, choose "open shell"
run the following command:
pkgcmd -u -t tpk -n com.samsung.health.samd.bp
I tried but the result was:
sh-3.2$ pkgcmd -u -t tpk -n com.samsung.health.samd.bp
