My phone is locked, as explained here.

Since I can't find the password, I want to backup my data before a reset. I've just installed Android Studio and Samsung USB driver.

  • Boot my phone on "apply update from ADB" mode.
  • Open Windows CMD, run adb.exe devices
  • It list my device as sideload mode

How can I pull my data now??

Is there a way I can backup my data before a reset and without voiding the warranty??

No, in "sideload mode" you can only apply updates via adb sideload filename.zip, no other ADB commands are available, except adb devices of course.


Just had a similar problem. Look at this: How-To Geek - How to Copy TWRP Android Backups to Your PC for Safe Keeping

In case you have TWRP installed or manage to somehow do so, then remember to take out the "Enable MTP" option in the "Mount" section of TWRP.

  • Don't even know what TWRP is.
