How To Guide Root Guide for Galaxy Tab S8/S8+/S8Ultra

[cbb77]

Hello, I have a question related to the update process.

I rooted my Tab S8 and downloaded the latest firmware with Frija but I didn't get any CP-file. Do I need the CP-file or can I skip this option in Odin? And if I do, where can I get it? Why isn't Frija downloading it?

There is no CP file needed. Just skip that and fill the rest in Odin. Since you are asking that I would recommend reading the instructions on the first page of this thread thoroughly. I am getting the sense that this may be your first time updating. Just make sure you are using the correct files and options correctly.

This is probably a dumb question but here I go.

I have rooted Tab S8 Plus but I want to completely remove root and leave it as factory for my wife, she doesn't care about root at all and just want to use it normally and update it normally.

If I use Odin with the original Firmware would it work?

Sorry of this is not the place to ask.

Yes, if you use odin to flash the firmware it will be "un-rooted". But the bootloader will still be unlocked. Sounds to me like that would be ok.. . Except for the dumb azz message at boot.

Edit: You can re-lock bootloader so you can get software updates and get rid of the funky message at boot.

Aren't you going to be tell him what the CP file is for?

 

[cbb77]

Sorry, you are correct I should have mentioned that. CP file is usually found for the celluar versions, which would contain the appropriate modem for that model. I assume you have the Wifi version, of which would not have a CP file. If you have a carrier version, make sure you downloaded the correct firmware version.

I have read about this on the thread about my phone. ( not Samsung ) It was bad news. They said that when the boot loader was un-locked, you cannot re-lock it. Maybe. Maybe the Samsung repair people can ?

 

[jhill110]

Ok, for those who would like to know... You can re-lock your bootloader :

With the Tab shut off press power and vol up and vol down at the same time (pressing the middle of the volume button will accomplish vol up and down) while also being connected to your computer with a USB cable you'll see:

Volume up long press unlock /lock mode
Volume up continue
Volume down cancel (reboot)

Long press volume up and choose re lock bootloader
Re-boot your device

That's all there is to it.
Bootloader will be re-locked and no more annoying red message.

Two questions if you don't mind:

1) Does this only work if you have reflashed stock firmware, or is it also safe to do this if you are running the magisk patched image?

2) Is there any difference between relocking the bootloader that way or toggling the bootloader lock button back on in the developers options?

 

[jhill110]

You can re-lock the bootloader anytime. The firmware you are running has no effect.
EDIT: Of course root will no longer exist.

The toggle in developer options will NOT re-lock the bootloader. Assuming it's not grayed out.
I don't get it. Sometimes it's grayed out sometimes not. Right now it's not on my S8 +.

My toggle is not greyed out but I am afraid to touch it, because I had read on some other topics that relocking your bootloader on a modified firmware with root could cause bootloops...
So you are saying that on a rooted magisk image, that toggle would do absolutely nothing?
And relocking the bootloader on a magisk patched firmware through the method you described would make you lose root, remove the warning message on boot, and being unable to update normally outside of odin (because firmware still not official), is all that correct?

I don't know exactly what it would do if anything .
On my Tab s7 when I re-locked before trading it in it caused a factory reset.
The warning message was gone.
And it was able to update through normal means. As far as the device knows it's all normal again.
BTW, Samsung has never said a word about the supposed e-fuse being blown. I've traded up twice post root... My Tab s6 to s7 and my S7 to s8+. They just don't care... No matter what people say. The one's that just like to make everything a crisis.
DON'T worry about this stuff re locking will just set it back to out of the box condition.

That was refering to system root. Magisk is systemless.

You mean the bootloops occuring after relocking the bootloader would only happen on a normal root, not magisk rooted roms?
Do you know the differences between relocking using jhill110 method and doing it from the dev options if the toggle is not greyed out there?

Yes, because with magisk you’re ours simply lose root upon the factory reset that happens when the BL locks.

i think that locking it using the oem unlock switch is a visual glitch, and if not, it would simply leave your device unlocked without letting you relock it (won’t give you access to Unlock/lock bootloader mode).

 

[Arealhooman]

In concept, if I used this, how would I get back to stock recovery and kernel.

That sounds like bad news if that dev options relock switch did this, leaving you unlocked with no way to relock or flash original firmware. Now I'm afraid of that switch for other reasons lol. If a brave soul tries it, please let us know what happens.

5. In Settings > Apps, search for Google Play Services and Google Play Store and clear all data (not just cache) for each
6. Reboot
   1. NOTE - This is currently only passing Widevine level 3, so Netflix is limited to SD. I'm still trying to figure out how to get L1 / full HD.

Very good. easy to follow, worked without fault. thankyou

 

[dodeca]

Have been rooting quite a number of device by now, following quite a number of HOWTOs.
None of the latter ever came close in conciseness to this Root Guide.
Got hands on my new Tab S8 Ultra today. Took me less than an hour. Done. Rooted.

Mega-Kudos to the OP!

"NOTE - This is currently only passing Widevine level 3, so Netflix is limited to SD. I'm still trying to figure out how to get L1 / full HD."

This one, keeping me away from rooting for now, as i watch a lot Netflix in the tablet.. If anyone resolve this, please post the solution..
Thanks,
