I just tried those instructions, they didn't work for me. Seems like possibly a timing issue. It used to be that volume up+power would get you into recovery, almost 100% guaranteed. But on some of their newer devices, that doesn't always work. It's been reported to them long ago, but apparently never fixed.

If you're rooted then you can just use the Magisk app to get into recovery without hassle, no futzing around with buttons or having to use a PC/commands. Works every time. You will still have to wait on bootloader message to go away. It's the circular arrow button to the left of the settings icon.

Edit: That same vbmeta i linked works on 11 and 12. It's the only one I've ever used, no issues. Even when upgrading the firmware, that vbmeta continues to work.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] SavXL:
I tried using the method you said where you hold vol+ and power, but when I try doing it, it doesn't take me out of download mode. I also put the vbmeta tar in userdata and flashed it but it just brought me to android. When I used the other vbmeta and put it in AP, it sent me to stock recovery and asked me to format data. Is there something I'm doing wrong with either of these things?
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] AnonVendetta:
When I used the vbmeta, I always flashed it on top of a stock firmware that had been flashed with Odin. After leaving download mode, it didn't even try to boot Android. It just took me straight to stock recovery with a message saying I would need to reset. I expected this, having done it numerous times already. Not sure what's going on in your case.

If it only took you to Android, then maybe you had flashed that file before. Which means no signature change. I was never able to boot into android with the vbmeta I've linked, without a reset.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] SavXL:
When I was initially trying to get twrp installed, I used the old vbmeta that was different from the one you used. I put it in the AP slot and it did exactly what you described in your case. I guess at this point, I could just flash twrp again and install magisk from there and then try to change the recovery file in /vendor to keep it from changing to stock.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] AnonVendetta:
Patching your boot image is the recommended way of installing magisk on Samsung devices, not from TWRP. It also says this on magisk's official help pages. Installing from recovery may also work, but it's less than ideal.

Installing Magisk

You dont need to patch the entire huge AP firmware file, if you have already flashed the firmware package and are just wanting to root. Use these instructions to patch boot.img only (will still get you fully rooted, and you'll be flashing a much smaller file):

Patch boot.img

the boot.img also needs to come from the same firmware, dont try to use others. Best to use a boot.img whose version exactly matches the firmware.

Patching the entire AP is apparently only necessary if you want to upgrade without losing root.

The recommended order I use when installing a new Android version:

1. Flash full official firmware with Odin (I always do clean flashes only, never upgrades that don't require wiping data)

2. Boot android, connect to net, enable developer options, make sure OEM unlocking is enabled

3. Flash vbmeta in Odin

4. Reset again, and redo step 2

5. Flash Magisk. Once you are back in Android, you can use magisk to reboot to download mode

6. Flash twrp in Odin.

7. Boot twrp, flash @ianmacd's Samsung multi disabler zip (I do this mainly to disable forced encryption of data partition, if you want it then skip this. But you won't be able to do backups of data from TWRP without them being huge).

8. While you're still in twrp, do this so Android doesn't overwrite your TWRP with stock recovery.

Prevent stock recovery from coming back

9. Do a factory reset from TWRP/format data (to remove any encryption on data partition)

After this you are done, boot Android and set things up to your liking.

My process takes an hour to finish at most. It can seem a little slow the first time around. I've been doing the same thing for months and it has always worked, so I'm not changing it.

I am in need of a quick confirmation on exactly the steps I should take, please...

I have the SM-T970 (gts7xlwifi) and before I found this thread, I was able to get it updated to Android 12 and rooted with Magisk. It is working great and I just want to get TWRP added. Exactly what steps do I need to take in light of that? Do I have to do another format/wipe, or can I literally just rename the TWRP-gts7xl-3.6.0_11-A12-1a7_ianmacd.img to recovery.img, then tar it, and flash that in download mode with odin?

Or, do I need to do other steps and/or basically start from scratch? Thanks!
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] AnonVendetta:
@robroy90: You shouldnt need to start from scratch. Just do steps 6, 7 (optional, but if you do this then you must format data/factory reset to remove encryption), and 8 from my post directly above yours. Tar the recovery.img and flash in Odin.

We have the exact same model and i'm also running Android 12 CVA5 firmware, so my steps should work for you.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] robroy90:
Thank you very much, I appreciate that! I will give it a go then!
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] AnonVendetta:
@robroy90: @ianmacd posts newer versions of his Android 12 TWRP in his Telegram channel. I suggest you install the app, register a free account, and subscribe to the channel (it's mentioned on first post of this thread). Right now I'm using a newer build than the one you mentioned. My suggestion is to get the img from there instead of his AndroidFileHost link. They usually have bugs fixed. Just rename it to recovery.img and tar it, same as usual.

If you want to update your TWRP in the future, no need to use Odin. Just put it on tablet and flash the img from within TWRP (it has an img flash option built in).

No.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] Michael Carleone:
HI. Some questions:

1. how to find (and determine) what official firmware you have currently installed?

2. where to find your OEM firmware (links)?

1. where do you get vbmeta, link?

2. how to verify OEM unlocking is enabled?

Hopefully you can clarify. Thanks.

I so wish I could do this, never used to have troubles but my depression medication makes me to zombified.

Is there any Australian that have done it that could send me an image of it done?

This would be great thankyou, please
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] AnonVendetta:
The firmware version you're running should be listed in the Settings app in the About section (it's on the same screen as the build # info).

You can get your firmware from Frija. I also use galaxyfirmware.com and SamFW.

The neutralized vbmeta I use is at vbmeta. Use the vbmeta_disabled.tar file, flash it in Odin in the userdata slot, not AP. You will most like have to do a data wipe/factory reset after flashing this, Android probably won't boot. It's a 1 time thing, vbmeta will stay neutralized unless you flash an official firmware. So, backup any important info beforehand.

You can check the status of OEM unlocking in developer options. If it's disabled and grayed out (can't be toggled), you're fully unlocked. You won't be able to flash amy thing other than stock images, unless this is disabled.

Hey guys , new to the tablet modding always on note series , anywhom I have a SM-T978U 5G Tablet with Android 12 baseband CVA6 with January 1 , 2022 patch can this be rooted and modded with twrp & magisk ?

I read that after 12 update it's not possible to mod it ... I am able to downgrade to android 11

Any suggestions ?

Loving this tablet but wish I could at least root it :)

Thanks for reading and thank you in advance for any output you will have for me ...
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] Y2Ne1:
Would you happen to know the channels name or link I will definitely check those two or one group out thank you
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] AnonVendetta:
@Y2Ne1: Android 12 is definitely rootable, I did it myself. And since you have a Tab S7+, TWRP should work too. No TWRP for Tab S7 (non plus), only root. That's part of the reason I bought the plus model instead.

I've downgraded to Android 11 BUJ3, because some things on 12 werent working as expected.

I can't remember the name of @ianmacd's TWRP channel, but you can find it in his 1st post on his Tab S7+ TWRP thread.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] Y2Ne1:

[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] SavXL:
I've installed TWRP on this tablet before but I kiiiiiinda forgot the process and need to do it again after flashing stock everything for a specific need. I've patched my S7+'s firmware with magisk but I'm having difficulties flashing TWRP and making it stay. I've tried renaming /vendors/recovery-from-boot.p to recovery-from-boot.p.bak, but it fails on Solid Explorer (access denied) and with ZArchiver (completed but with errors: pretty much access denied). I could probably rename it from TWRP directly, but the issue of not being able to boot into it after flashing is giving me trouble. As far as I know, I can't boot to recovery from Odin nor can I use an ADB or fastboot command while in download mode. So I'm at a loss. Does anyone know how to get this installed and keep it installed? I've completely forgotten how to do it now.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] AnonVendetta:
I thought you were buying the Tab S8? Got cold feet and bought the Tab S7+ instead? It's still a very powerful device, I see no compelling reason to upgrade. It does everything i need it to do.

Can you get into TWRP at all? If so then just use my instructions from a previous post in this thread (it requires typing a few commands before you will be able to rename it successfully). You must be sure to do this before exiting TWRP, if you can get in at all.

If you're trying to do it from Android, make sure Magisk is working first. I was able to rename it with Total Commander when i tried months ago. Go to the file's location, in the bottom right of TC you will see an icon that has 2 squares/2 arrows. Tap it, the hidden bottom toolbar will appear. On that, tap the RW button and confirm. Then you can rename the file. If it still doesnt work, then i would say your root isnt working correctly.

So far I'm back to running Android 11 BUJ3 (didnt like 12 so i downgraded). I have Magisk and TWRP installed, i've always been able to get into recovery (using my own methods that i've posted here).

Is it possible to update firmware through TWRP and keep magisk ?

If yes, please provide steps 🔥🔥
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] DHGE:
No
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] Arakawa.:
No, you can't do that with official firmware.

But it can be done with a lot of third-party firmware. The question is, this tab have no third-party firmware…

So, in your case. If you wish to update your firmware. You have to flash updated official firmware then flash magisk again and you will lose your data in the progress.

My recommendation is if there are no issues you need fix or some new functions you want. Then don't update. Not worth the trouble.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] aliabd0:
I always update firmware using Odin with patched AP file .. This way I could keep my data and root access

I just wondered if there's an easier way
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] Arakawa.:
As far as I know, no easier way.

And about your method. It seems you're missing things from BL and CSC? Like optics and prism. Incomplete update may or may not cause problems.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] kgursu:
Hi everyone.

I have a question about correct selection of TWRP for my device and if it is possible to update it without wiping data.

I have a SM-T970, which has firmware with a name ending "_1_20210121210134_84ml313a23_fac.zip" installed.

PDA and CSC codes are T970XXU1BUAA and T9700OXM1BUAA respectively.

I have a TWRP installed, which seems to have code 3 and that could be incorrect. The full code is 3.5.0_10-A11_3_ianmacd, which I've got here before.

I need to update firmware with SM-T970_1_20211013115614_pst141die2_fac.zip, which PDA and CSC codes are T970XXU2BUJ3 and T970OXM2BUJ3 respectively.

I want to update with Magisk patched AP file, which is a tar file only, which secures the update without data loss.

Could I update TWRP without data loss? If not, would the previous installed TWRP be affected by ODIN dirty flashing? Also would the previous TWRP work with the new firmware? Is it incorrect because of that coding mismatch?

Thanks.

[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] kgursu:
After several chat on Telegram, these happened:

After carefully considering, I decided to flash Magisk patched AP file with BL and HOME_CSC, added to this your recovery twrp-gts7xl-3.5.0_10-A11_3_ianmacd.img shall be renamed to recovery.img and put it in a tar file and flashed as Userdata.

I think the keycombo for Download mode and Recovery mode are a bit complex, as you need to follow these:

Download Mode: Hold Volume Down, plugin cable, then use Power-Side-Bixby button

Recovery Mode: Hold Volume Up, plugin cable, then use Power-Side-Bixby button

I disabled Auto-Reboot on Odin, but I couldn't shut down my device, as it can be restarted with Volume Down and Power button only, by pressing them 7 seconds.

I have recommendation of booting into recovery with key combination, while USB connection remains, in my notes, but this was not valid for me.

After waiting a while, the device powered off itself, thankfully.

I flashed multidisabler on TWRP again, and rebooted. System optimized apps for the new version of firmware, but I cannot pass the logo after that. I got back to TWRP and wiped Dalvik and cache. The result is the same.

The new question is:

Shall I update the TWRP from twrp-gts7xl-3.5.0_10-A11_3_ianmacd.img to this twrp-gts7xl-3.5.2_10-A11_1_ianmacd.img? I saw some issues related to this, where devices are unable to shutdown on Download mode. Is that the case?

Even so, that would require a complete data reset.

Most importantly, how could I correct current status of my device? Could multidisabler the culprit and be troubleshooted?

Thanks.

@ianmacd: Samsung has pushed the first Android 13 updates for the Tab S7+, about to flash. For now, I'm going to try the A12 TWRP to see if it will stIill work with the new firmware. When and if you have time, maybe you can push a new TWRP build too? In the meantime, I'll keep an eye on your Telegram group, it's usually the first to know about new releases.

Did the new firmware work with the A12 TWRP?
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] AnonVendetta:
From what I can tell, the new A13 firmware works 100% with A12 TWRP. Rooting process is the same. I'm not running the stock rom anymore, I went right back to an A13 gsi ROM (by @phhusson).

I just had to try it though, Samsung's version. Definitely feels improved. But when I do flash new firmware, I mainly do it to ensure that critical system components like bootloader/vendor are up to date. There honestly is nothing in the stock roms that would make me want to continue using them, the gsi ROM experience is so much better. To me, anyway. Cleaner, much less bloat, slightly better battery life.

Use Treble Info app by Hackintosh Five to determine what gsis you can use. I'll shortcut it for you though, you need gsi files with "arm64" and "ab" in their name.

For an install guide:

https://xdaforums.com/t/guide-a10-a11-flashing-and-booting-gsi-on-galaxy-tab-s7.4282085/

I've posted a lot in that thread too, some of my info might be useful to you.

And one more thing, if you want read/write mount access to the "system" partition, you'll need to use gsi files with "vndklite" in the filename. If you install a non-vndklite gsi variant and try to edit stuff in there, it will fail and you'll get errors, even with root access. If you don't care about that, you can just ignore the vndklite gsi variants.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] Vishnarov:
is there any way to hard break the tablet with this gsi ROMs , I mean if something goes wrong can I to fix it with stock rom flashed with Odin ? and one more question ...this gsi roms are flashed with TWRP , right ?..because I see just one file .img.xz. What is the process of flashing ?
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] AnonVendetta:
DO NOT FLASH TWRP or GSIs, they will hardbrick your tab. And it will burst into flames and start singing "Great balls of fire!" by Jerry Lee Lewis.

.....Just kidding. Yes, you can flash the stock ROM with Odin if something doesn't work. GSIs are flashed with TWRP, yes. Or fastboot, but Samsung devices don't have that, generally. You could even use Odin to flash a gsi, but you would have to unpack/repack your super.img. TWRP recommended, it's the easiest way.

Trust me, just try it already. Put in some effort and just do it, it will be worth your time. But you have to try. So yeah, TRY, if something doesnt work then ask more questions. I wouldn't be recommending any of this if I hadnt just stepped out and put in the effort. And I definitely wouldn't be recommending anything, if I'd encountered serious issues like hardbricking.

It's not rocket science, sooner or later you just have to try. If you use common sense and think before doing, things will work out fine.

How the hell would I know?! I dont own your exact model. Just try already. I've already told you, if you have a Tab S7 *PLUS* with an unlocked bootloader, then it will most likely work. I even requested you to positively confirm your model with a screenshot, but you sent nothing. The only reason I asked was because I didn't want to give you bad advice by mistakenly telling you to flash a TWRP build on a non-plus device, since it almost certainly wouldn't work.

And just so you know, I own a Tab S7 Plus 5g variant, my model is SM-T976N. This TWRP build boots fine on it, so does the build by @afaneh92.
