I delete my files and still can't free up memory. I was reading that bloat could be located under /data/lost+found but I don't know how to access it without root. I've tried to root using SuperSu and TWRP. I downloaded Odin, I downloaded the Samsung USB Drivers, and I installed multiple TWRP files using the `AP` button in Odin.

I get stuck at the Samsung load screen, and can't run recovery mode.

I don't want to load any new Roms, I just want to get sudo access so I can access /data/lost+found

Can someone please help?

SuperSU, really? That's been dead for years, download Magisk instead ;)

The basic of rooting:

*Install recovery TWRP for your tab
*Install magisk trough TWRP
*Debloat your lovely TAB...please

If you downloaded magisk.zip ,you can also change the extension to .apk

Awesome! This is what I'm looking for! So to unlock the bootloader, I download Odin? When I put the tablet in download mode, Odin can then flash the TWRP recovery image. Then when I restart, I can install magisk?

I think I'm running into an issue where the backlight for my tablet is not displaying (the TWRP UI). I'm verifying.

Hello Androidgeek230,

Unlocking bootloader means,your /Data map will completely wiped.no more guarentee from Samsung (fun part )

* go on your tablet to the about section and tab 10 times to activate developer options, enter it and select OEM unlock + Adb USB debugging

*Install USB driver for samsung tab
*shutdown Tab
*While pressin "Volume UP + volume Down button,connect your Tab with USb cable to PC (maybe in background device driver is being installed.
*Device is in unlock mode,select volume Up again to enter "bootloader"
*Select again volume up to unlock bootloader.
Now your tab is Unlocked and will restart installing Android,couple minutes later your in Android again.

Now you must install recovery TWRP with ADB

regards

about the developer options:

Step 1: Go to Settings > About Phone.
Step 2: Tap Software Info > Build Number.
Step 3: Tap Build Number seven times. After the first few taps, you should see the steps counting down until you unlock the developer options.

Hi Tresans,

I want to see what's in my /data/lost+found though. Is there a way to do that?

Thanks for the detailed instructions! I was able to do this and I can see developer options.

I don't see OEM unlock anywhere, though.

Hello,

OEM unlock feature is in the developer options,together with USB debugging.

Or it is greyed out,cause of already boatloader unlocked.

    Sorry Nimueh,

    I downloaded Magisk. What do I do now?
    I linked you the XDA Magisk threads in my last post so you'd read them ... if your device has a custom recovery then you flash Magisk in it, if not then you have to manually patch + flash the boot image of your rom.

    Check the Magisk subforum here on XDA, if you can't find your answer there then those good folks are much better at answering your questions ;)

    Or simply use ADB App Control if your only reason for rooting is to remove/disable unwanted apps. It can do it without root, easily and with a GUI over ADB.

    Thanks for the adb control app,i will definitely use this on my tablet without recovery
