[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] whoosename:
Kingo root installed? Very bad! You have to unroot and root again. To unroot properly, flash rom and twrp again and then flash Magisk. I'd flash the 17.1.

[MENTION=4899305]ashyx[/MENTION] Hi! There is a method to update from one stock version to another without formatting data and not breaking the system? I tried to update with home csc and then flashing patches, but when I booted settings app was messed up showing weird menus and duplicate shortcuts, and overall system was bugged.

Any one updated successfully or only clean flash?

Or maybe I can clean flash and then restore data from previous Rom?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ianmacd:
It sounds as if you didn't reboot to stock recovery, following installation. That's when the CSC is installed. If you skip that, you'll end up with Korean menu options and duplicates.

You can reflash the CSC zip to remedy this.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] pankozin:
Yeah, I already figured it out.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] imasandwich:
I need help

I didn't read all of the details and flashed twrp, now I'm stuck in a bootloop. I tried flashing stock firmware but I got all sorts of errors like emmc write fail aboot and unsupport dev type. also trwp fails mount /data for some reason
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bloodstains:
This all worked for me and my device is rooted. However Im trying to get rid of the warning "Unauthorized actions have been detected......" There are alot of post here but i tried to find ones relevant to this problem. However I have already disabled "SecurityLogAgent" and have installed both T820XXU1BRE2_dmverity_patched_boot & Tabs3_oreo_forced encryption_disabler.

any ideas what next to try?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Are you sure Securitylogagent is disabled? That is all you should need to do.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bloodstains:
im using Service Disabler - which is different from the post i saw, idk if that matters though. What do you use?

The post i saw recommended using Package Disabler

but i didnt see that in the store, only Pack Disabler Pro, and the ratings where low so i wasnt sure if that was right
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Search for the app securitylogagent disable on play.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ianmacd:
Alternatively, you may already own a root app that can do it, such as Titanium Backup or SD Maid. Neither should be absent from any rooted device, IMHO.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Rattor:
I have both of those. How do you use them to disable the security logger?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ianmacd:
Select SecurityLogAgent in the relevant app module and choose the Freeze option.

Alternatively, you can mount /system and just delete the .apk, but I prefer to freeze, as the frozen status persists even after a firmware update.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Or the manual way via terminal/adb:

su

pm disable com.samsung.android.securitylogagent

So, what exactly does tripping Knox lose me? Will I not be able to get warranty service on the device? Is there anyway to reset the Knox counter, by flashing full stock?

I just got my device today, and I wanted to root early since I don't want to set everything up if I end up having to wipe it all during root, but maybe I should wait for a couple weeks/months to make sure I'm passed the early failure threshold before tripping Knox, if it means I can't return it or get warranty service.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Rattor:
I'm getting virus warnings for the T820XXU1BRE2_dmverity_patched_boot file when I try to download it. Is there another way to get it cleanly, or is that expected? Also, is there a BRJ1 patched boot file, or will this one work identically for that firmware?

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] davidk21770:
I'm not sure what option you're taking about - otg? (Maybe a language difference? I use mtp - media transport protocol - to transfer files.)

But, with an earlier version of the ROM, usb-mtp did not work, but it is now.

When I plug in the usb, there is a notification that I can toggle to mtp or I can go to the developer configuration and change it there.

If it doesn't, are you at the correct vendor? Have you tried a simple dirty reinstall of the ROM?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] risant:
i used T820 stock rom oreo rooted .. the usb drive notification keep on flashing connected then disconnected... usb drive cannot be mounted in recovery TWRP
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] davidk21770:
Sorry-I thought I was in the ROM thread.

USB has always worked for me with this twrp.

You probably tried this - but have you tried a different cable?

SM-T820 USA Odin files 10/1/ 2018 Android security pach level

I am thankful to have my working TWRP backup of my rooted xposed SM-T820 thanks to [MENTION=4899305]ashyx[/MENTION]. But if any want to reinstall [MENTION=4899305]ashyx[/MENTION]'s rooted TWRP recovery from the latest USA stock Oreo 8.0.0 Odin image, info is here on XDA forums.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Rattor:
You actually don't need this. I didn't use the patched boot because Magisk disables dm-verity during install. It pulls your current boot image, injects the dm-verity disable, and then flashes it back to your device. As long as you flash Magisk during the first TWRP cycle, it'll disable dm-verity and not throw you into a bootloop.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Nonny_SA:
Hello,

I would like to ask something because of my OTG isnt working , before it was with the cable an usb drives , on my Note 8 with the same methode rooted it still works, here some info

Everything is working well and its an exelent manual for rooting the tablett , that at first !

1. when i boot i have in the upper left corner a message with yellow letters says Set warranty bit: Kernel <--- i belive thats it

2. i Used here the Magisk root 17.1 + TWRP 3.2.1-1

3. all is exelent working !! :D

But the OTG with the before root working Hardware dont work anymore.

I connect the OTG cable and it keeps flashing like : USB Adapter conected , then USB Adapter Disconected ... and that all , its like in a loop , is there maybe someone who know how to fix / repair this ? would be nice :)

Like i say this Tablett and the Galaxy Note 8 are very close in rooting but in the note 8 its working fine , no problem with OTG ...

Thanks for the good rooting manual

Greetings

I am in same boat, so>

0. I am on stock stock BRJ1 for t825

1. Install twrp (as boss described)

2. format data???

3. Instal magisk latest, all over???

4. reboot and have stock magisk rooted, is it?

thanks
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Rattor:
I did this:

1) Install TWRP like it says in first post.

2) Boot to TWRP

3) Flash forced encryption disable

4) Format data

5) Don't reboot, go back up in the TWRP menus and make sure you can mount data in TWRP

6) Flash Magisk

7) Reboot

If all went well, you should boot into the TabS3 setup procedure.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ivanox1972:
Thanks friend! [MENTION=1271181]Rattor[/MENTION] which magisk, latest?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Rattor:
I flashed the latest. I think it was 17.3?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ivanox1972:
And [MENTION=1271181]Rattor[/MENTION] if I just want to install custom rom (only one twz which exists) how then to do?

As I understand it has dm variety inside patched so: just twrp, format data full wipe and install?

Is it?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Rattor:
Yeah, I think that should do it. And that ROM is pre-rooted, so you shouldn't need to install Magisk. Just follow the instructions on the ROM page for activating root.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Reneval:
I have the same Problem with USB OTG.

Stick connects and reconnects and again and again.

Iam on BRJ1 right now (T820).

Would be Happy about some help.

Thank you!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Is this in recovery?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Reneval:
It is in recovery and in OS, too.

With BRE2 the USB OTG is working great.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Nonny_SA:
Hello I can confirm that it isnt wotking on TWRP "mount OTG" and also not in the OS , in my case its Oreo 8.0.0

I have the SM-T825 with firmware BRJ1 , the rest looks working fine so fare just OTG is missing :(

Please take a look at this

Greetings from Southamerica

Nonny :cowboy:
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Considering its both the OS and twrp then I can only assume Samsung disabled OTG in the kernel as TWRP cannot affect the OS.

Can anyone confirm if OTG worked previously in TWRP?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Nonny_SA:
Uh , i didnt tested it but as i reflashed everything from scratch (4 parts firmware over Odin) , otg was working , then i flashed with odin the TWRP and after this no more OTG was working , before i didnt tested it , sorry :(

Greetings

Nonny

EDIT: i found also out that 2 files where missing ,

1. android.hardware.usb.host.xml

2. android.acessory .... something i have to take a look,

and in the file: handheld_core_hardware.xml

under permissions was text missing

<feature name="android.hardware.usb.host" />

it trys to connect but cant finish the process and trys it again and again ...

well buut without flashing anything like all stock it was working well ...

Nonny
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Reneval:
Yes, i can confirm that exactly.

As soon i flash TWRP, i can't mount any USB in OS or TWRP. It works only with firmware BRE2.

Greetings from Germany!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Hang on, you're saying with no other mods whatsoever, no root, no custom kernel that as soon as you flash twrp, OTG doesn't work in the OS?

I honestly have no idea how that is even possible? :confused::eek:
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Nonny_SA:
As strange as it sounds but here the same , first i was thinking i made something wrong so i resett everything to "0" and then it works fine , TWRP flashed and the OTG mount is gone , its true i tested it on the Oreo 8.0 2 times , and cabel an usb drive was working before TWRP , in my note 8 cabel an UBS drive ist still working so the cabel and Flashdrive are fine ... looks realy like there is something deep hidden in the TWRP .. , in TWRP it self the OTG mount funktion is visible but not possible to activate with cable pluged in or without no activation possible ...

Greetings

Nonny
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
TWRP is located on a totally separate partition to the OS .You don't even need an OS installed to boot to TWRP. The ONLY modification TWRP does is to patch a file in the system partition which prevents TWRP being overwritten by stock recovery. This file has no relation whatsoever to anything USB related.

if you can get it working again in the OS, plug in the OTG device then using adb or a terminal app type mount and post the output.

Also the output of:

ls -laR /dev/block

would help.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Nonny_SA:
I can tray to do that but in that case i have to resett all over again , that can take a moment if that is ok i can do that later on , i could be that i need some help for get the log files corect or this ADB installet this i do not have on my mashine here righte now ....

if there is norone else how can do this i will re-flash all but later on , not right now :)

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Reneval:
maybe it's because of that file:

T820XXU1BRE2_dmverity_patched_boot

because its optimized for BRE2 and this firmware works fine with usb in my case ?

iam not a dev or something, its only a Suggestion ?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Nonny_SA:
I tryed to see the terminal program helped to see the momands "Mount" and "ls -laR /dev/block" are working , this was the output :

do that help somehow , no right ? i belive i need a explanation how to take out the logs in a good way ...

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
The USB device needs to be connected for it to be of any help.

Also I suggest using Terminal emulator for Android by Jack Palevich.

Termux has issues.

Before typing any command you need a root shell.

Type 'su' first then the command.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Thanks, you're doing fine. Unfortunately nothing regarding the USB mount point is showing in the output.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Nonny_SA:
Ok , i was thinking that too because it dosent compleete the mount process , ok then i will flash again but i need a little time for that , i will post the logs then when i am done , do you have a link for the ADB install , i remember long time ago there was a slim version of ADB for some fast boot comands you have maybe a link so i can download it for installing , the compleete ADB is a big program i belive just for the logs its too much ...

EDIT: here i found this : https://www.xda-developers.com/install-adb-windows-macos-linux/ ,, this should do the trick right ? there is a ADB download file i will try this one !

Thanks.

Btw. Otg works
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Reneval:
Ok, today i test some things regarding USB OTG.

I got the T820 Model.

First, i flash the latest firmware BRJ1 (DBT) from scratch again.

Reboot the OS and OTG works fine.

After that i installed TWRP and Bootpatch.

TWRP works fine, data partition is mounted, but it cannot find the stick.

In TWRP in red letters stand: e: recv error on uevent

data partition is still mounted, that is no problem.

after that i boot in OS and it cannot find the USB, too.

the stick is mounting and dismounting in a loop. i can see that in the statusbar.

so i think its something in the TWRP, that is not working with the 2 firmwares, that came after BRE2, which works perfect.

they must changes anything in firmwares BRG3 and BRJ1.

so i think, we need a fixed TWRP for that firmwares or something.

hope it can help.

too bad, that OTG is a very important feature for me.

to have OTG and a fully functional TWRP iam thinking to go back to BRE2 firmware.

greetings and a nice weekend to you all!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Nonny_SA:
Exactly that happends here , i dont know is that the same with the before firmware , no idea i dont teted it , but when its working fine with the before firmware and TWRP well mybe when there is no other solution that could help ! :cowboy:

thank you, i wish that to you, too :)

---------- Post added at 02:04 PM ---------- Previous post was at 01:53 PM ----------

without bootpatch the same result.

TWRP says: recv error on uevent and cannot recognize the stick.

Update: after all i have installed this rom

SM-T820_BRJ1_TWEAKED_3.8m_DB4_by_rorymc928

over anything without format data.

now the OTG in OS works again with this rom. a few posts before somebody has confirmed that, too.

but in TWRP its not working like before.

strange ?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Nonny_SA:
It looks like this is for the SM-T820 , do you have this model ? Maybe the TWRP is for that reason differend because you have the SM-T825 ?

---------- Post added at 08:10 AM ---------- Previous post was at 08:08 AM ----------

@ashyx , just a question , was the log somehow helpful ? or like the logs before nothing showing up with the OTG mount ?

It shouldn't give you any options. You should just select the file and then there should be a slider at the bottom of the page to start the installation.
