To Enable the Developer Options on your device follow the below steps:

Now Scrool down to and Toggle the USB Debugging option on. CONFIRM
Back out of settings

Power off your device. Press Volume Up + Volume Down THEN plug your Tablet lnto a PC to boot into download mode.

Oem unlock is not there!

If you want to unlock your Bootloader and your Tablet is less than 7 days old (USA)
OEM unlock option will not be available

Heres what to do:
You MUST be signed into WiFi and your Google account or your Samsung account

Open Settings on your Tablet
Go to General management
Tick Date and time
Untick "Automatic date and time"
Tap "Set date"
Set date to a month ago
The system needs to think you’ve had the device for more than 7 days.
Back out

In Settings go to Developer options
Untick Software update
Back out of Developer options

Go to Software update
Untick Auto download over Wi-Fi
Back out

Reboot your Tablet
OK! OEM unlock option should be available now in Developer options

Hey can you make a detail guide like this to root s7 plus WiFi version, I see a post by a user name nightmare but it’s not detailed and I’m new to rooting, thanks.

  • Hey can you make a detail guide like this to root s7 plus WiFi version, I see a post by a user name nightmare but it’s not detailed and I’m new to rooting, thanks.

    set it up, connect to internet, enable dev settings and toggle oem unlock, turn tab off then hold all buttons down while plugging in, long press up to unlock bl, let it wipe, set it up, connect internet and make sure bl is unlocked, flash disabled vbmeta (optional), flash twrp then hold buttons to go to recovery, format data, flash disabler, flash magisk?

    its really easy

    just follow twrp guide then flash magisk

    Ok, I'm going to make a couple of assumptions here :

    1. Bootloader is unlocked.
    2. I assume you have a magisk patched AP file or BOOT file (see my patched boot file thread in this forum) . If not follow instructions for making one elsewhere in this forum. MAKE SURE patched file is from your current firmware version!

    Flash magisk_patched file in ODIN (AP SLOT) and let ODIN reboot your device.

    If magisk manager is not installed install it.

    Install magisk 20.4 from magisk manager and let it do it's thing and reboot.

    That's it.

    There seems to be a little confusion about tripping KNOX when rooting....
    Unlocking the Bootloader and Rooting with Magisk Manager DOES NOT trip KNOX. You can root and still maintain your KNOX warranty status.

    If you're OK with just using Titanium Backup and not TWRP your KNOX status will remain OK. 0x0

    you are mistaken.. unlocking bl and rooting with magisk absolutely trips knox.. just because magisk uses magiskhide and sets props to make it appear not tripped to try and bypass some security checks doesnt mean knox is not tripped.. unlocking phone and flashing any modified firmware including magisk patched boot.img trips knox.. always has and always will

    I am a bit confused reading all the postings about rooting and tripping knox.
    I'd like to root to make use of adblockers etc, but I want to watch netflix/amazon still in HD (wdevine 1 needed).
    Is that in any way possible when rooted?

    mind letting us know if the procedure worked and if u r still on widevine 1?

    Bootloader unlock, TWRP and Magisk.
    Getting S7+, then planning to unroot and lock bootloader on S6 and sell on. Hopefully people will still buy even though knox tripped. I'll have to disclose that

      @jhill110: Unlocking the boot loader has worked on my new SM-T970 as described. Thank you very much for the detailed steps! Now going further to root and TWRP now.. :)

      I fat fingered the firmware number... it's SM-T878U.
      Looks like TMB is the only one available for download.
      Samfrew .com has SPR, TMB, USC, and VZW.
