I would appreciate some help.
It seems Samsung or Whatsapp updated my mobile and all my Wahatsapp contacts and chat were deleted.
Unfortunately, I did not have backup.
I am trying to recover the data using " Free Android Data Recovery "
Unfortunately it is not working . Asking for Rooting Permission.
I have tried software from
Downloaded the PC software from Kingo above ( Not the mobile App ) . Its process went to 100 % and then reported : Fail.
Not sure what else I should do to make it work . I have allowed Debugging and OEM.
Or I need another reliable and safe software to use on my PC ( Windows 7 ) to get my mobile rooted.
I don't want to download apps on my mobile as it will overwrite my data. Also I have turned off wifi on my mobile to stop further data coming in and overwriting my Data.
