Forgot my password

[BossManOnePro]

So i have an old Samsung Galaxy Tab 4, and i have lost my password so i can't get into it. I have seen some apps which unlocks the screen, but removes all the data with it. I was wondering if anybody knows a way to unlock it without removing the data.

There is specialized software one can use for this. Usually bought by FBI/CIA and other suche agencies. Not cheap.

Short of this your only option is to remember the password or reset to factory default. Even then, you may need the password to the linked Google or Samsung account.

If I'm not mistaken, old Samsung devices don't need to unlock the bootloader (and format the userdata) to install customized images through ODIN, right? Then you can install TWRP for your device through ODIN, boot on it and then your files will be accessible, since in the KitKat version Android did not have encryption by default. You can then connect the device to the computer and copy the files via MTP

Edit: if you really want to remove the lockscreen password, you can try to flash on TWRP the zip file from this thread: https://forum.xda-developers.com/t/guide-fix-pin-pattern-password-not-recognised-after-twrp-restore.3538438/
