Recover Deleted Files in Android Internal Memory & SD Card

1.  First of all - You need to STOP using your device with immediate effect to prevent any further data loss.

2.  The Best method to recover your precious data either deleted or formatted is to connect your device to your PC in USB Storage Mode (Not in MTP or PTP mode) and Download the above listed software Get Data Back for FAT and NTFS, follow the above link for further help. 3.  Run the Get Data Back for FAT application with administrative privileges, as most probably your default internal or external SD card storage would be mounted/formatted as FAT partition either 16 or 32. 4.  Now select your required drive either internal or external storage as required and thoroughly scan your storage. After this has been done, You'll be presented with the list of folders with random names. 5.  Now you need to select and copy files needed to any other media such as your local disk or Windows desktop. WARNING: Never use same storage as of recovery drive as this will reduce the quality of data to be recovered, otherwise you won't be able to recover files if you again need to scan your device for lost files. .  6. If you can't connect to your PC, Download these two softwares Undelete for Root Users and Disk Digger PRO - Both apps require Root Access, otherwise they won't work ! ! ! Also try the Wondershare Dr. Fone for Android - PC based data recovery software (More accurate recovery and  recommended)

7.  Run Undelete for Root Users and Scan your Internal SD Card thoroughly to get the best results when recovering data.

8.  You'll be presented with lots of files to recover (if available in good condition*). All you need to do is to restore those files onto External SD Card of your device. . . Remember: Never select Internal SD Card for Recovering your lost data of Internal SD Card and Vice-Versa otherwise it'll reduce the chances of recovering your data next time you use these or any other data recovery software available out there.

9.  Furthermore you can run Disk Digger PRO to get more results for recovery of files but Disk Digger provides with a lot of fragmented files as well because of the nature of Flash Memory and Android for saving files in a scattered manner when low on space. . This way resulting number of fragments of files increasing and thereby reducing the chances of data recovery (Just as in Windows, Mac or any other Operating System)

10.  You are Done . . More ways to restore data to be added soon.

* Good condition here indicates that the files deleted have not been overwritten in any manner and are in single fragment.

Update 1: I'm currently working on to develop an app to allow other users (those lacking the support of mass storage/usb storage mode + internal sd mount on their devices) to use Mass Storage/Usb Storage mode on their devices as well. . Will update this post when done in succession .
