Team Win Recovery Project 3.x (TWRP3)​

TWRP3 is a custom recovery designed for ease of use and customization. It features a fully touch-driven interface, eliminating the need for volume rocker or power buttons. The GUI is XML-driven and fully theme-able, allowing customization of the look and feel.

* Your warranty is now void.
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or your getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.

Supported devices: X710, X816B, X916B (but to be fair any

unlocked

Tab S9 should work)

The galaxy tab s9

FE

series is NOT supported by me and this thread

Instructions:

Flash twrp recovery and vbmeta in your preffered flashing software at the same time (odin3, heimdall, odin4 etc)

Once booted into twrp flash provided repack.zip to disable replacing of twrp with stock recovery upon boot

Enjoy?

Bugs:

wow! I have been waiting for this. Thank You!
[Samsung Galaxy Tab S9 series] tnchng:
You're the Saviour!

Tested and booted perfectly on S9 Ultra on latest ROM (February Patch).
[Samsung Galaxy Tab S9 series] fsantiago21:
Worked on my Tab S9. Thank you! I hope that we can start seeing custom ROM’s appearing soon.
[Samsung Galaxy Tab S9 series] Anghirrim:
Woo thank you so much!!

For the Tab S9 FE, I guess this is a totally different beast and that the Exynos (vs Snapdragon) SoC makes it unrealistic to try using your work as a base for any development?

Edit: seems like the Galaxy A54 is using the same SoC and just got his first TWRP release too, I may have a look. Never built TWRP before, but ported several custom roms already.
[Samsung Galaxy Tab S9 series] Rainbow_Dash:
I haven't had a look yet but if a54 and s9fe have same soc you might* just get away with swapping kernel modules and touch fw (if needed) in device tree. You can use mine as reference since it's built upon my fold5 dt.
[Samsung Galaxy Tab S9 series] Anghirrim:
Well I'll have a look at how to do/build TWRP. I haven't deal with a device tree since two or three years, last time I build Android was on A11.

Thanks for your proposal!
[Samsung Galaxy Tab S9 series] Azkali:
Good job ! Just rooted and installed your TWRP on my freshly unboxed gts9wifi it works fine.

I am looking to decrypt userdata cause I am porting Ubuntu Touch to the device so userdata must be decrypted, I'll try to port over the changes I have from my Fold 3 port to your device tree and see if it helps and make a PR if needed.

Would you consider making a OrangeFox recovery as well ? (it uses the same device tree and is very straight forward to port over)

Linking you my sources for both stuff in case you want to look into any of the 2 things yourself.

Fold 3 recovery device tree source
[Samsung Galaxy Tab S9 series] Rainbow_Dash:
Oh hi.

I've made 0 attempts at implementing decryption since my usecase doesn't really involve it. I would rather just convert vendor to f2fs and disable it outright. But adding it should be simple enough by adding standard keymaster qcom hals. I will look into it sometime later since why not. If i don't, contributions are always welcome.

As for orangefox..... Idk a recovery has simple enough purpouse and since i would rather spend as little time in it as possible i don't really care what it is. TWRP is fine and familiar. I have no reason to look into alternatives.

But hey, if you want to build it my trees are open source for a reason, have at it!
[Samsung Galaxy Tab S9 series] Azkali:
Thanks for the quick answer, you said convert vendor to f2fs but vendor isn't involved here.

Regarding userdata, seems to me like the only missing piece is keymaster qcom hals then.
[Samsung Galaxy Tab S9 series] Rainbow_Dash:
If things haven't changed, i imagine you can still disable encryption by editing fstab from vendor to delete argument containing it. Afterwards formatting data. Problem is vendor is readonly erofs
[Samsung Galaxy Tab S9 series] Azkali:
Ah yes just like the multidisabler script does, gotcha, I have that script in my recovery as well and do it that way too
[Samsung Galaxy Tab S9 series] user82791:
Worked on Tab s9 5g. Thank you!
[Samsung Galaxy Tab S9 series] jutley:
Can someone make a quick guide how to flash this to device inc unlocking bootloader and rooting please.
[Samsung Galaxy Tab S9 series] RagManX:
As soon as I have some free time, I'll install this on my S9+. Thanks for providing this - I will let folks know whether I'm successful. But I'm confident it will work.
[Samsung Galaxy Tab S9 series] ArchVisions:
Hello, this is awesome! I unfortunately, have the Tab S9 FE. Do you think add support for it?
[Samsung Galaxy Tab S9 series] David Walton:
Any idea when this (if ever) will come out as an official version available on the TWRP website? I see there is no official version for the Samsung Galaxy Tab S8 series there either.
[Samsung Galaxy Tab S9 series] leplic:
Will try tomorrow on my s9 ultra. Thank you for this
[Samsung Galaxy Tab S9 series] tnchng:
For X816B, black screen, can't touch, but adb is working, plz fix it.
[Samsung Galaxy Tab S9 series] Rainbow_Dash:
i think i figured out why, can you (or anyone else with a tab s9+) try this image?
[Samsung Galaxy Tab S9 series] ArchVisions:
Hello, may I ask what do you mean swapping the kernel modules (I am quite new to building)? I built TWRP for the Tab S9 FE, but for some reason it after booting from download mode to recovery, the device will remain on the bootup screen. This certainly isn't because the vbmeta.img as it is an empty one. Could this possible be something with me not integrating multi-disabler?
[Samsung Galaxy Tab S9 series] Rainbow_Dash:
The recovery partition is well contained in the sense that you don't need much else to boot it apart from a functional bootloader.

You have a kernel (boot) partition, but this is included as a prebuilt in twrp dt

You have a kernel modules (vendor_boot) partition which is also included in twrp dt, making it independent from ones already on device

You have dtb, dtbo etc, again independent

This redundancy assuming that what you have on device is broken, unreadable, etc. Recovery has its own copy of everything crucial

Extact stock recovery using omosis' android image kitchen. In the ramdisk folder you will find /lib/modules. Grab them and replace them into your device tree.

Resulting in Something like this

You will also have something along the lines of split-img-dtb which will be your prebuilt dtb you need to replace, dtbo can be found in AP firmware. I'm pretty sure you also will have to rebuild kernel....unless it's also based on linux 5.15

Hope this helps and good luck!
[Samsung Galaxy Tab S9 series] ArchVisions:
Ah, thanks for the information. This will certainly help. I will then instead try to use BlackMesa123's a54 device tree and fork it (and swap the kernel modules, stuff like that).

As I stated before I already built a previous device tree and wanted to ask what exactly I did wrong with it. It was successfully built, but it failed to boot: https://github.com/InfiniteVariatio...-13-TP1A.220624.014-X510XXS2BXB3-release-keys
[Samsung Galaxy Tab S9 series] ArchVisions:
And yes, thankfully, the tablet is based on 5.15. I already tried building a kernel in the past and uhh, that didn't go well.
[Samsung Galaxy Tab S9 series] Rainbow_Dash:
From what i can see you don't have kernel modules atall in that tree so that's something you need to do.

Also you will need a custom kernel with permissive and security/defex disabled
[Samsung Galaxy Tab S9 series] ArchVisions:
Where can I get a kernel with defex disabled? I tried to create my own before, but frankly failed.
[Samsung Galaxy Tab S9 series] Rainbow_Dash:
you guessed it

you build it :P
[Samsung Galaxy Tab S9 series] ArchVisions:
Lol, will I may then boot up and install other linux enviroment, then.

What about when you mentioned that I wouldn't have to build a kernel with Linux 5.15?
[Samsung Galaxy Tab S9 series] ArchVisions:
What about this? Can you elaborate (I hope you don't mind me asking all these questions)?
[Samsung Galaxy Tab S9 series] Rainbow_Dash:
the kernel (boot.img) should (in theory) be common for all devices based on linux 5.15 due to GKI architecture.

In reality i've seen samsung make small changes to this common kernel branch. I'm 90% sure you won't run into issues but eh

If you do you're on your own with prebuilt kernels
[Samsung Galaxy Tab S9 series] ArchVisions:
Ah, well I will try and create a new device tree and start from there.
[Samsung Galaxy Tab S9 series] tnchng:
I'm traveling. I'll try when go home.
[Samsung Galaxy Tab S9 series] Kingcuong1988:
Hello,

I just recently got my tab s9 ultra and would like to root it.

Is there a tutorial to root it with what is posted here?

I am having trouble of understanding some steps.

Do I have to download a firmware or can I just use the firmware which is already installed on my tablet?
[Samsung Galaxy Tab S9 series] ArchVisions:
Hello! You can't pull the boot.img for Magisk without root. You need to download the firmware from Sammobile or SamFW, and make sure it matches with the right firmware version of your device.

Here check out the thread here for the Tab S8 series. Scroll to the 3rd post a follow from there. https://xdaforums.com/t/root-guide-for-galaxy-tab-s8-s8-s8ultra.4423095/

The steps to root are virtually the same for the Tab S9 series. Keep in mind though, after rooting, Knox will be tripped and you will no longer be able to use apps like Samsung Pass and Wallet.

For the other Samsung apps you can use Knox Patch: https://github.com/Mesa-Labs-Archive/KnoxPatch

Rooting is definitely worth it for some people. Don't do it just because other people are. It is your decision so you have to choose wisely. I rooted my Tab S9 FE because I wanted to get rid of some system apps, and google apps, and just have more control over my device.

Good luck, and keep me updated! :)
[Samsung Galaxy Tab S9 series] Kingcuong1988:
Thank you very much for the detailed instructions! I will give it a try later and hope I'm doing it all right and it won't brick.

I rooted my phone already a few years ago, but I feel like it got more complicated or I just got older 😀
[Samsung Galaxy Tab S9 series] ArchVisions:
No worries! Good luck!
[Samsung Galaxy Tab S9 series] Anghirrim:
Hi,

Thanks for the info. I am giving it a go for now.

So I did build the A54 TWRP using the following sources (I did not put anything in vendor). Build went OK:

- TWRP Mini AOSP ==> https://github.com/minimal-manifest-twrp/platform_manifest_twrp_aosp.git (branch=twrp-12.1)

- BlackMesa's A54 device tree ==> https://github.com/device/samsung/a54x (branch=android-12.1)

- BlackMesa's A54 kernel ==> https://github.com/kernel/samsung/s5e8835" (branch=sep-15/twrp-12.1

To make an attempt for the S9FE, according to your message above, I did take the latest A14 firrmware from SamMobile and extracted it (renamed the AP.xxx.tar.md5 by adding .zip).

I then "just" copy/pasted the content of the following

X510XXU1BWKB_X510OXM1BWKB_EUX/AP_X510XXU1BWKB_X510XXU1BWKB_MQB74521037_REV00_user_low_ship_MULTI_CERT_meta_OS14.tar/RECOVERY/RAMDISK/lib/modules

Into my X510 Device tree (this is the a54x that I copy/pasted and updated the makefiles):

/sources/TWRP/device/samsung/X510/recovery/root/lib/modules

And also copy/pasted the samsung firmware /RECOVERY/dtb into my device tree prebuilt/ folder

Then clean built.

Finally, based on BlackMesa123's guidance, I update the avb header file of my TWRP version with the one from the stock recovery using magiskboot:

magiskboot unpack -n -h stock_recovery_X510XXS2BXB3.img
magiskboot unpack -n -h TWRP_X510.img

Replaced TWRP header file with Stock header file then repacked it and made the .tar version.

magiskboot repack -n TWRP_X510.img TWRP_X510_signed.img
tar -cvf signed_TWRP_X510.img.tar TWRP_X510_signed.img

Side note: You'll notice that modules are from X510XXU1BWKB while the header is from X510XXS2BXB3. It's just that I started building with what I had available while downloading the latest X510XXS2BXB3. I don't know if it'll impact the build.

So attempt to TWRP Build for the Galaxy Tab S9 FE (SM-X510) is available here: https://drive.google.com/file/d/13u5gDaUWmfwjWa8UznpHhFCbON5gVq0g/view?usp=drive_link
[Samsung Galaxy Tab S9 series] ArchVisions:
Yeah, you should be fine. I actually instead started with a basic skeleton generated from the recovery, adapted the tree, adding the kernel modules, and editing some things from there.

Oh, and pretty much the only thing I did differently was copied the /recovery/dtb/ into the prebuilt folder. If you want I can test it out, if you can send the recovery.img. I have a good feeling that it may have to be signed first to even boot.
[Samsung Galaxy Tab S9 series] ArchVisions:
Here are the commits from my tree: https://github.com/InfiniteVariations1/android_device_samsung_gts9fewifi/commits/android-12.1/
[Samsung Galaxy Tab S9 series] Anghirrim:
Edited: All of what I did is now written two messages above. Including a link to my attempted TWRP for Galaxy Tab S9 FE.

@Rainbow_Dash , if it boots, I'll stop squatting your thread and open a new one. ;)

Hey, yeah, so I tried to boot the custom recovery and compared to my attempt of booting my own built version of TWRP I got something different:

ODIN MODE (SVB FAIL)!

recovery: No footer detected (0)

recovery: Error verifying vbmeta image: Invalid vbmeta header (6)

[Samsung Galaxy Tab S9 series] Anghirrim:
Hi @Rainbow_Dash , quick question.

Does the "image" in our device tree needs to be a prebuilt dedicated kernel?

Thanks,
[Samsung Galaxy Tab S9 series] Rainbow_Dash:
Yeah, it needs to be a kernel image (not an entire boot.img which has a ramdisk) set to permissive with security (defex) disabled. You can also check my source for reference
[Samsung Galaxy Tab S9 series] ArchVisions:
Done that. I built my own kernel with permissive and security disabled. Me and @Anghirrim are trying to figure out why TWRP isn't booting. This is probably something with the AVB footer, but regardless, it's still bootlooping. The kmsg log won't help either as that is unable to be retrieved.
[Samsung Galaxy Tab S9 series] Rainbow_Dash:
Somehow doubt. But well the latest exynos i have experience with is the 9825 so maybe they changed something along these years. Again, you should look at a kmsg (/proc/last_kmsg) to figure out what's wrong. Better than just blind guesses
[Samsung Galaxy Tab S9 series] Anghirrim:
Thanks for the answer.

As explained by @ArchVisions , we're now going blind with the bootloop issue.

Is there any way to get logs?

While for the avb footer, I was told to use magiskboot to unpack/repack the twrp build to add the proper footer. Is it enough or we're missing something?

Thanks!

Edit: Nevermind, just saw your answer.
[Samsung Galaxy Tab S9 series] Rainbow_Dash:
Have a rooted system

try to boot twrp once or twice

it won't boot

boot back into system

grab a copy of /proc/last_kmsg

study kernel boot log

I'm kinda pissed off at samsung that they killed UART through USB with USB-C (unless you have token) so the method above will do
[Samsung Galaxy Tab S9 series] ArchVisions:
I tried already, I can't. When TWRP is flashed I can even boot into system.
[Samsung Galaxy Tab S9 series] Rainbow_Dash:
Then quickly flash stock recovery and hope log won't be long enough that it overwrites old twrp one
[Samsung Galaxy Tab S9 series] ArchVisions:
Might as well try.
[Samsung Galaxy Tab S9 series] Anghirrim:
Hey! It worked. ArchVisions managed to grab a log, and we isolated the TWRP flash/bootloop part.

Seems like while booting, avb fails verifying some hash.
[Samsung Galaxy Tab S9 series] Rainbow_Dash:
we don't care about avb. If it was a vbmeta issue it would've kicked you to odin mode mentioning it

i'm afraid to ask, but why is it looking for a modem interface and why does it seem to think it's running on a galaxy A54?

you did take kernel modules, dtb and dtbo from

YOUR

stock firmware images, right?

only the kernel image can be common
[Samsung Galaxy Tab S9 series] Anghirrim:
Hey, thanks for taking the time. I saw this too, but couldn't interprete it.

- Prebuilt kernel is built by @ArchVisions based off stock S9 FE kernel

- Device tree, I adapted the A54 device tree by replacing all prebuilt/ramdisk/lib/module content with the ones from stock S9 FE firmware. dtb also.

But I did not find the dtbo. So that might be the culpright.

Ah and I also of course updated the makefiles to create a new build target called X510.

Finally, my local_manifest also gets the Exynos 1380 common kernel sources used on both the A54 and S9FE.

I did not touch it, but the kernel sources are in my TWRP build directory.

Hope I was clear.
[Samsung Galaxy Tab S9 series] ArchVisions:
You can simply grab the dtbo from the stock firmware.
[Samsung Galaxy Tab S9 series] ArchVisions:
That actually makes sense. That has happened to me a couple times because of AVB.

Huh, I didn't notice that. I was primarily looking for recovery, how does the modem have anything to do with recovery?
[Samsung Galaxy Tab S9 series] Rainbow_Dash:
first thing i searched for is 'reboot reason' or just 'reboot'

it points to me when in time the device decided to reboot, since just before it will mention the reason it does it

in this case it was a kernel panic

even if we wouldn't have noticed the part of 'CP interface driver probe failed' and knew CP is nickname for modem (which your wifi only tablet doesn't have), 'Hardware name: Samsung A54X' should immediately have jumped to our attention

as for why recovery needs it, maybe it's for updating modem firmware with OTAs, maybe it's just normal hardware initialization routine, who knows. If it wasn't modem it would've been something else would've went wrong since you have wrong dtbo
[Samsung Galaxy Tab S9 series] ArchVisions:
Looking further with this, there are multiple parts of the ksmg log that state:

[ 0.756160] [7: init: 1] Hardware name: Samsung A54X SEA OPEN board based on S5E8835 (DT)

This makes sense as the SOC is based off the A54 as both devices use the same chip. It is definitely possible that Samsung may have simply used a similar or same board as the A54.
[Samsung Galaxy Tab S9 series] ArchVisions:
Huh, very interesting. I think I will go ahead a try to build TWRP instead with BlackMesa's device tree, and replace the AVB header and see how that turns out.
[Samsung Galaxy Tab S9 series] ArchVisions:
Without the modem of course.
[Samsung Galaxy Tab S9 series] Rainbow_Dash:
Sounds plausible but highly highly doubt it

If the dtbo he used in his tree wasn't the one for his device it would explain the wrong hardware name.

Just checked my flip4's kmsg and it does report correct codename (b4q), my tab isn't rooted right now so can't check
[Samsung Galaxy Tab S9 series] ArchVisions:
Ah, ok. Then, I am adapting my tree at the moment I replaced the kernel modules, and renamed the files to fit gts9fewifi, not a54x. I will also use my prebuilt kernel, and replace dtb from the one from split-img, and get the dtbo.img from the stock firmware. Should i adapt anything else before I build?
[Samsung Galaxy Tab S9 series] Rainbow_Dash:
You find dtbo from AP file from stock firmware. This is your issue.

Here, i uploaded one from X510 firmware
[Samsung Galaxy Tab S9 series] ArchVisions:
Thanks
[Samsung Galaxy Tab S9 series] Rainbow_Dash:
you might find yourself without a touchscreen since it might need firmware to be included, but it should at the very least boot and show a picture regardless.

good luck
[Samsung Galaxy Tab S9 series] ArchVisions:
Thank you! I will keep that in mind.
[Samsung Galaxy Tab S9 series] ArchVisions:
Well, it was bootlooping again. I checked the ksmg log, and this time there aren't any signs of a54 anywhere. Although I still see this same line about the hash:

avb_slot_verify.c:417: DEBUG: recovery: Loading entire partition.
avb_slot_verify.c:540: ERROR: recovery: Hash of data does not match digest in descriptor

Same with the AVB signature:

[0: 6.366123] check_signature (RECOVERY) invalid.
[0: 6.366129] update_image_status_auth: Status for RECOVERY image is already custom
[0: 6.366134] set_ddi_kernel_type : RECOVERY, 0x8
[0: 6.366139] No need to update kernel type.
[0: 6.366142] make_security_decisions : (RECOVERY)

I will add the ksmg log for you to check out.
[Samsung Galaxy Tab S9 series] ArchVisions:
Oh and you'll see 2 flashes in Odin mode. One to flash TWRP, another flashing stock.
[Samsung Galaxy Tab S9 series] Anghirrim:
Uh, it's 8Mo!?

In our stock firmware, there is a file (the only named *dtbo*):

/AP/RECOVERY/recovery_dtbo (541,1Ko)

In the device tree I use:

/TWRPsourcedirectory/device/samsung/X510/prebuilt/dtbo.img (779,6Ko)

When I wrote yesterday that I did not find the dtbo.img, it was not entirely true. I did find the recovery_dtbo, but decided not to use it as I was unsure if it was the right one, to avoid making a mistake.

Ok, I'll try a build with it today. And also check on BlakcMesa's source code if there is any remain of the mention to A54 that I have missed.
[Samsung Galaxy Tab S9 series] ArchVisions:
Awesome. I will test it later when it is built. I got to head to sleep now. It's 1 am here.
