And yes I have written over the new data every time i booted into new rom. So to be precise I have formatted and written over the data more than 7-8 times.
SO please tell me how are the chances of me getting the file from Stock rom back?
PS: The files were 3 video files each around 400 mb
Waiting for your reply sir
Formatting isn't a problem. It doesn't delete the data.
Your memory is broken into blocks (Now This isn't accurate, but lets pretend it is...) so it starts at block 1 and ends at block 100...
You save a video to sdcard and its the first data stored there, it goes to block 1.. The next data goes to 2 etc.
When you format, the entires in the file system are removed, but the data remains, until you overwrite data. Since the file system is empty, after a wipe, the data starts from block 1 again, overwritting the previous data in block one.
Once this happens, its gone forever. So your chance is small....
The only chance you can save data is for example, before wipe, used 8GB memory. After wipe only used 4 GB data.. The last blocks of your previous data set (4 GB) MAY be recoverable.
