Hello my friend has a samsung galaxy s3 mini recently the phone has been connected to kies and during the connection there was a problem and this problem does not allow access to the phone itself, the links at the bottom of the page you will find photos that they were made by the owner of the phone itself that shows the error that gives the terminal.

The questions that I have:

1 - it can reinstall the boot (as in windows with fixboot and fixmbr) so that he can restart the phone without losing data?

2 - you can boot your phone into Safe mode and you can save the contents or on a Micro SD or cloud?

3 - and possible after re-flashing the system retrieve the data and thus treat the phone's memory as if it were un'hdd a pc?

Thank you all for any help you can provide me.
