What to do when there is no backup of the deleted data and the data is urgently required?
You could try to undelete it but there is no guarantee that the integrity of the data will be intact.
first is to turn off the machine, don't do any read write operations on that drive, this includes surfing the web
use another machine to install a portable file recovery software on a pen drive or ssd. Recuva is good.
it is a good idea to take an image of the hard drive in its existing state as well (this step can be skipped)
use the pen drive to run the software and recover the files
there is no guarantee that this will work
@others, please pitch in
^ I would've done the same. Download the portable version of recuva on another system and run it using a pendrive.
Until and unless the deleted data is written over by something else, it would be possible to recover it completely.
Important: don't try to use your phone any more after losing the data, otherwise the data will be overwritten and unrecoverable.
There are top 5 recover software in the market,you could try.
1. Coolmuster Recovery for Android
2. Wondershare Dr. Fone for Android
3. Tenoshare Android Data Recovery
4. Eassos Android Data Recovery
5. Recuva
Dr. Fone requires the phone to be rooted. I already tried that with my OP3.
^^ Hehe Yeah life got busy! Nah dude, 1st I gotta root my OP3. Even Recuva needs the phone to be rooted.
