Hi [MENTION=2320544]rorymc928[/MENTION] !

I'll try tomorrow your new build (5.1b) and also try to flash it via a TWRP I ported myself (which will not be available until I test it and works).

I have a question; is it possible to port One UI 2.1 to this beauty of tablet? (like from the Tab S4 or Tab S6 ?)

Because I think in my opinion it would be great to have an updated Android 10 ROM on this tablet, since you're actually the only maintainer for this tablet that actually updates his ROM frequently, and your ROMs are the greatest thing the Tab S3 series have right now!.

I saw on another thread on XDA how to do that and I would like to know your opinion: https://xdaforums.com/android/general/how-to-port-samsung-rom-to-samsung-t3481114

Thanks for replying us!. :)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
Thanks, it's good to get a test on the T825.

I'll have a look at the thread, I think Samsung is making it harder in a lot of respects, I use a tab s6 now and just briefly attempted a ROM for it with no success.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
Thx for the nudge. ;)

I did it with the tweaked ROM and it was much easier than I thought.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] HippoMan:
I have an SM-T825 that is flashed with a recent (but not latest) version of this ROM. I want to flash the latest, but before I do, I have a question:

It says the following in the OP: "Best flashed over updated firmware". Does this mean that it's best to be flashed over the bootloader that is referenced in the OP?

If so, that is a dead link. Is there a better location to get this latest bootloader now?

Once I find this bootloader software, could someone point me to instructions for flashing this bootloader via a linux box? Would this have to be done via heimdall, with the following command, perhaps? ...

heimdall flash --BOOTLOADER /path/to/bootloader.bin

Thank you very much in advance.

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
If you're running a pie version at the moment, it will be that simple. However if you're on oreo it will need a bootloader update at least.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
The longer story,

When flashing over oreo with the first pie rom ,all seemed fine but it became apparent that the fingerprint reader did not function, flashing the oreo bootloader fixed that. I've just uploaded the latest oreo bootloader .

https://androidfilehost.com/?fid=8889791610682891483

I suspect the earlier pie bootloader would be fine,if thats what your on, if not you should use the latest.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] HippoMan:
Thank you for explaining. This makes sense. I'll just flash the latest ROM (after a nandroid backup, of course!), and if it works, I'm home free. If not, I'll restore my OS and then try flashing this oreo bootloader before re-flashing the ROM.

And thank you for all your work on this ROM!

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] vegych:
The question arose

Is it possible to roll back to 7 android on this firmware?

Do I need to flash the old bootloader? And which version with 7 android, because I only see from June 2018 and this is most likely 8 android.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
deleted for I misinterpreted vegych's post
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] vegych:
7 version I mean in this assembly

SM-T825 TWEAKED 2.1 02APR2018

But there is no link to this build

So I have a question, is it possible to roll back like this
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] reygm:
Install instructions?

someone know what are the installation instructions? :(
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
Post 1 not good enough?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
Not having tried, I'd suggest you'd need an earlier bootloader to get it to boot, often rolling the bootloader back that far is not possible.

All the roms are available with a search on android file host,

Splash logo query

Thanks for the tweaked rom.

Before i flash i want to ask will the tablet show warning about custom rom at startup and will i be required to press power button every time the tab is started or rebooted ?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
My T825 didn't notice.

What do you mean with the pwr button?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] nuke3dl:
My rooted Samsung A505F used to show a warning at boot splash that this device is using a custom rom, press power button to continue, then i found a fix at xda to go back to normal screen.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
No, a small script appears in yellow in the top left, but no prompt or power button requirement.

My tab s6 cycles through the screens you mention, however if you ignore the first, ie,not press the power button, after a pause on the first screen, it will still proceed to the boot screen in any case
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] nuke3dl:
Thank you for your reply
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Zera01:
@rorymc928

Thanks for this ROM.

It's working.

One thing that should be changed in the next version: magisk should not be installed as system app.

Magisk throws a warning at start.

I had to remove it in TWRP with file manger and do a fresh install.

And there are a lot more samsung apps that can be safely removed. I used magisk debloat + busybox module and termux app.

Debloat list can be found here:

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] switchgott:
Any idea why we cant boot a cutom kernel from pie?

I tried now over 8 weeks to build a custom kernel working on stock pie.

No way.

Does someone have an idea why the kernel wont boot?

Any security restiction inside rom and ramdisk?

I tried it also with anykernel3 to keep all stock.

No no...i never had such problems. My own kernel for s10 s20 and a lot more a working well.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] DartGerion:
@rorymc928 Hi, wanted to ask, is there a possibility to update magisk or to make it systemless?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] DartGerion:
Hi, how did you resolve that warning with magisk? Could give me some pointers?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bozkurtum:
Can't this rom be upgraded to higher android versions?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
There's no higher stock by Samsung.

You could use android 11 by @Awesometic.

He published LOS and Havoc, from which I prefer the latter.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bozkurtum:
I installed this rom on my t827 tablet to use the phone feature, but unfortunately I could not make a phone call. Do you have any suggestions for this?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bozkurtum:
Did you manage to update the magisk app?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
Has it been updated to latest stock from 2020-06-01?

It's the turkisch, not Verizon model, isn't it?

https://samfrew.com/model/SM-T827/
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bozkurtum:
yes this model is tablet
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
Well, as mine is T825 I might not be able to help you further.

Calls on mine are working.

Were they working on yours when being on pure stock?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bozkurtum:
My t827 tablet did not have a sim card and phone aroma with stock rom, so I rooted and installed the custom t825 rom, but the phone did not open for calls. thank you
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Srambo217:
Hey guys, haven't used this tablet in a while but I'm going out of town for work and would like to use this for media on my trip. I just updated to this ROM from CSH9, but I'm unable to get video service apps like HBO Max, Hulu, or Netflix to work. Enabled blocking through Magisk, but I assume it's too old of a version? Anyone know how I can easily update Magisk and block root from these video apps? Thanks.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
Update for Magisk is available directly through the Magisk app
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
Sounds like you may have forgotten the rmm bypass stage. You'll need to go right back to stock and begin again.

Have a good read of this guide,"https://xdaforums.com/t/rom-sm-t820-tweaked-rom-sm-t820-tweaked.3659433/post-84161803" follow it exactly. Good luck
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] lupick:
Thank you. Can you share your experience with this rom compare with stock one?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] KainanMaki:
Very good so far. I'm going back and forth between stock and this rom to work on other stuff, but the first impressions are pretty good.

Now I'm dedicating to debloat activities, which forces me to stay in stock most of the time.

But I can't wait to flash the rom again and debloat it.

[MENTION=2320544]rorymc928[/MENTION] will you be updating this Rom to the latest version T825JXU1ARC1? Even though the Changelist is same as ARA2, ARC1 has April Security patches included.. Thanks for all your hardwork..
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
Sorry for the delay, I'm a bit reluctant to use a firmware base from the list at the moment. I tend to choose them from more mainstream countries that don't have, shall we say, their own internal security issues. If one of them pops onto the list I'm quite happy to.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Kimple:
Thank you for tweaking SM-T825 ROM.

FYI

Oreo 8.0.0 for SM-T825 has been published on SamMobile https://www.sammobile.com/firmwares/galaxy-tab-s3/SM-T825/BTU/download/T825XXU1BRE2/218711/

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
OK new link is up

Tweaked 3.2 BRE2
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jaidev.s:
Thank you very much for this Rom..

My device has BRE3 baseband which supports VOLTE in my country..

I wanted to know if I flash this Rom, will my modem get changed to BRE2 baseband ?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
If you did a full wipe that's likely, if you dirty flash I can't be sure you may retain your present one, if not you could reflash the stock firmware to return. But you should make sure you have that on hand,

I have a WiFi T820 myself so, I'm not familiar with the significance of the change.

Your other option would be to wait for others to flash and ask the T825 users if they have it available for use. The files exist on both the T820 and T825 but that is obviously just a standard part of the firmware.

Hope that's of some help
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jaidev.s:
thank you very much for ur kind reply :)

on Nougat it was very easy to change Baseband by Odin flashing but on Oreo Baseband doesn't change after Odin flash (am talking about trying to change baseband of stock roms)

lets hope it will change on custom rom
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
Just had a look, this firmware base is UK, and apparently all mobile services in the uk have volte available, don't know if that helps.

[MENTION=2320544]rorymc928[/MENTION] hi, when i flashed , it got struck at creating/ data/ adb screen for lover 10 - 5min, so i panicked and rebooted the device..

luckily it booted and everything is working perfectly other than occasional pop up of x posed stopped working.. thank u very much,.,
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
OK sounds like an issue with xposed if you go to the xposed installer app. Uninstall framework then reinstall it should correct it

PS. Is volte working
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jaidev.s:
after reinstalling x posed, its working perfectly.. Thanks once again,..

VOLTE data is working but for making calls , i will have to install 3rd party apps..

BRE2 baseband doesnt support all the VOLTE bands in India while BRE3 supports all of them.. i tried to odin flash BRE3 csc after installing this rom but it didnt stick :(

now i will have to pick [MENTION=4899305]ashyx[/MENTION] brain once again for enabling BRE3 baseband .. he already helped me once, hope he will help me once more :fingers-crossed:

while flashing the Rom in TWRP , it got struck in this screen..

Three posts in different threads with identical question?

Bit to much imo.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
This is A TWRP installation issue, has occurred before. I've encountered it myself. Careful following of the process solves it. Unfortunately it requires going back to scratch to start again. The ROM works for most who don't fall into the trap. This blog is for the Rom, which whilst dated is successful. Flashing of recovery binaries is covered in the twrp posts.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] onolox:
Hi, I'm havig a problem with magisk 25.2, I used titanium backup to remove the old magisk that came with this rom(and install magisk as system app is not good) to install 25.2 via TWRP.

But I can't make zygisk to work. There's an error in the log. E umont2 /system/bin/appwidget failed operation not permitted

I tried to uninstall and reinstall but to no avail.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] lasyan3:
Hi, same error with my Samsung Galaxy S7, Magisk 25.2 (even canary branch).

Edit: ok found this link stating the kernel must by 3.19+. Since my gs7 uses Android 8 and Kernel 3.18.91, no wonder it doesn't work... I'll eventually switch to the last LineageOS and let you know if this works.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] gorcutt:
Hello, maybe someone here can point me to the right direction.

Had a hard time installing this ROM but I believe it is finally working correctly, but... I'm not able to make edxposed to work. Removed the one that came originally with the ROM, installed the new one from Magisk Repository (v0.5.2.2_4683-master from soluhsu). Later after a reboot this one asked to install the full one from Git v4.6.2 but I see the red message "EdXposed Framework is not (properly) installed". It tries to download something from an XDA URL but it fails with a 404 error, couldn't see the full URL. So, is it still possible to install EdXposed, is it still maintained? The download tab also points to someplace that doesn't looks like it's working. Thanks
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] gorcutt:
Actually the message from the download item in the menu is cannot connect to https://dl-xda.xposed.info. I believe the same message appears the first time I launch the edxposed app after a reboot. Thanks.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
Hi,

I'm a little out of touch with this tablet at the present, however on the tablet I use now I've shifted to lsposed, similar implementation, good guide on xda...

What is LSPosed, and what can you do with it on your Android device?

Curious to know about LSPosed? Here's how to install the Riru module via Magisk and what you can do with the Xposed Framework's successor.

Give it a try and post back

Good luck

I have a SM-T827V, bootloader's locked tight, can I still install this ROM? I'm on stock Pie right now.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
Afaik without an unlocked bootloader you can not flash anything which is not stock.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] NotALongUsername:
Well that's a bummer, is there a way for me to replicate the tweaks myself though? I'm looking to improve the performance of this tablet.

I've already purged all of the bloatware using the Universal Android Debloater, what else can I do on stock ROM?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
Perhaps there're additional options to get rid of some stuff using ADB but idk as I didn't try myself on my only device which is still on stock because I would loose the warranty then.

Another option may be using Netguard-no-root to block internet access for those apps you don't wanna use.

At least that's what I do.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] andrewx01:
I followed the steps from the first post, and after the first reboot, I got a "security error: this device has been flashed with unauthorised software and is locked." What did I do wrong?

Would a rom based on this India firmware solve your problem....T825JXU1BRE3/219201/
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jaidev.s:
Yes, it'll solve my VOLTE issue but I'm not sure if it'll create network issues for members from other countries :(

And Im really not sure if its worth your time to cook a rom just for me..
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
Sorry for the delay in answering, I'll have a look today. The cracked boot img may be an issue but I'll try to make one today also leaving the xposed framework out, you'll just need to install that the way you fixed the issue with xposed yesterday. It'll give me a chance to test that as a solution to that problem anyway.

There may be other volte users who would prefer a rom built for volte anyway.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
Ok uploading, BRE3 India version, try dirty flashing over what you have first, that may save reloading things.

Xposed has been taken from the zip as it wasn't loading properly, if you dirty flash you will probably have to get the xposed framework again through the xposed installer.

Things you can let me know.

If the zip installs without sticking

If xposed works OK

And have a good look at volte for others that may want to follow after you, I have no means of testing it.

PS. Make sure you have all backups, and keep the last zip version in case. The naming is the same so perhaps put it in a folder named old 3.2

Good luck
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jaidev.s:
Ok, sure.. I'll download it and flash it soon and will report :)

Thank you very much for taking so much time and effort for us :)

This is curious, sounds like Busybox didn't install, no real problem but it should have worked. Let me know how everything else goes, hope it sorts the volte issue. In the firmware there was 3 extra apps related to networks of which one or all may be what you need
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jaidev.s:
Xposed and root are working perfectly. VOLTE is not working, this has happened previously too while switching between BRE2 and BRE3 stock roms..So i will Odin flash stock BRE3 and then flash the new rom and see if VOLTE starts working.. thank u very much for ur efforts..

The rom is smooth and awesome..

Thanks once again
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
OK good, update me if anything of note happens. One thing could you look in system /xbin folder and see if there's a file called Busybox there.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jaidev.s:
Busybox is not there
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
OK thanks definitely the problem at install
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jaidev.s:
VOLTE is not there.. have attached the pics where VOLTE is enabled in stock rom while its just 4g in Tweaked rom ( in BRE2 also it shows as 4g)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
To be clear, is the settings switch, available..... Settings /connections /mobile networks /volte...

If the setting is available check that it is selected on.

If the setting is not there, flash of the India csc to match the rom should put it there

Use of the home csc through odin should leave your data intact

Could you please clarify to me whether the Oreo bootloader is the same for both t820 and t825?

I have a T825 rooted (magisk) and nougat rom AQD6 .

thanks
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
They're, not the same, the link in the op for the bootloader is for a T825 oreo. If coming direct to this rom, flash that via ODIN, if you need to update twrp do that first, best if you untick the auto reboot, saves the fumbling to beat the reboot, when that's done boot straight to TWRP for the rom flash. Let me know how it all goes

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
Yes, I've been experiencing this issue too, it will eventually get there. You can check if the screen is responsive by sliding the script up and down, or seeing if the double blue lines are still moving from the progress bar. Usually it is still working in the background. Can't be sure of the cause but suspect it's the huge size of the firmware.unpacked it's over 4gb.
