How to root Galaxy Tab S7(+). (GUIDE)

[AnonVendetta]

I don't know if you all noticed but there's another EUX update CVA5 out showing up on Frija
I flashed it works fine

CVA5 isn't showing up on galaxyfirmware.com, for either XAR or EUX. My PC stopped turning on a few weeks ago, so I have no easy way to flash it. Although I could probably call a friend and get him to loan me his spare laptop, if I really needed to use one.

Heres a link to it

Let me ask you a question maybe you know i can't seem to get a straight answer

What happens if your on a U1 unlocked version phone running U1 firmware and you flash your U carrier version using Home CFC so not to wipe.?

Will it still factory reset going from U1 to U and will you still get all the carrier version mess and bloatware even if you don't flash userdata ?

Not sure exactly what you're asking, so I can't answer. You say U and U1, but I think even the carrier firmwares would use either U1 or U2 (version 1 bootloader/version 2 bootloader). You can upgrade from U1 to U2, but you can't downgrade U2 to U1, Odin simply won't allow it and the bootloader will reject it.

As for the Home CSC thing, if that's what you flash then it shouldn't require a factory reset.

I would think that if you're flashing a carrier-branded firmware, you will still get all the bloat that comes with it. If you're not rooted, you can use a PC and ADB commands to disable the bloat you don't want. "adb pm disable" and "adb pm uninstall" are the commands you would want to use. You can also use a (paid) app on Play Store called LADB, that will essentially let you do the same thing, but not requiring a PC. It makes use of the wireless ADB debugging in Developer Options. Just Google "adb debloat" if you're interested in the specifics.

Just be very careful and very certain of what you're uninstalling/disabling if you go the ADB debloat route, since it can remove nearly *ANY* package installed, including important system apps. From which you probably won't be able to recover without flashing stock firmware. You can use an app called App Inspector to get the exact package names of what you want to remove, you'll need that for the commands.

What model of the Tab S7+ do you have?

I have a T970 S7+
What i mean by U1 is US Samsung direct factory unlocked phones that come loaded with U1 firmware U phones are US carrier based phones come with U carrier firmware
I want to flash my U1 phone from U1 to U firmware wondering if going from U1 to U will resent my phone is all

Apparently applying the patch using the latest magisk release on github did not work on my device with android 12. T875 CUCL. The tablet booted normally, but there was no preinstalled magisk manager. There are a few threads that suggest using magisk canary will work, so Ill try that. Also I think you can just patch the whole AP file, Ill try that too just to be sure. Pretty sure I did the same steps as I did before..

Are you using twrp ? Which version ? Can you point me to it.

The T875? no, I couldn't find any

Thanks for the quick reply. Looking hard but couldn't find any here as well

Unfortunately, I can't download that file from SamFrew. I started the download from the free link on that page, it says 10+ hours to finish. And I'm not going to pay them for the premium links either.

Its already showing up on Frija EUX version

Well, without a working PC, I wont be able to download it via Frija either. Besides some issues with my new PS4 controller disconnnecting semi-frequently, there's no pressing need to update right now.

I had just wanted to save it for later so I could flash it when I have a chance.

@Markeee: I've recently found that SamFW is much faster than SamFrew. Not only does SamFrew throttle the crap out of your downloads (because they want you to pay for the premium links), but their free option to download via Google Drive doesnt even work properly. I tried in several browsers and couldnt get the download to start with that option.

SM-T970 EUX T970XXU2CVA5 alternate link

With SamFW, even the free options are fast. You can just do a regular download in the browser. Or let SamFW access your Google Drive and download that way (probably the fastest option). Just make sure your browser allows pop-up windows or the download may not start. I also recommend using an app like Hash Droid (Play Store) to compare the MD5 checksum of the downloaded file, to the value shown on the site. If they match, your download isn't corrupt.

I'll probably try flashing this within the next few days.

Regarding how to update with root without losing data:
1. Use magisk to patch the extracted boot.img.
2. Flash the AP, BL, HOME_CSC with odin.
3. I have question here: do I flash the patched boot.img in odin without reboot immediately after step 2 (uncheck the auto reboot option in odin)? Or let device auto reboot with ODIN to system after step 2 and then power off and manually boot to download mode again to flash the patched boot.img?

Hi,

I know this guide is for the Tab S7 but is it applicable to the Tab S4 as well? Because the Tab S4 forums are dead and there's no up-to-date guide for rooting the latest firmware (which is Android 10).

Mine's already rooted but on an older firmware with an older Magisk version and I'd like to update everything.

Thanks guys!

 

[SlightlyWind]

You can backup your boot image to a different device or upload it somewhere and try it. The method is universal afaik. If however, it fails to boot for whatever reason, you can just use odin to flash the backed up boot image

Is it possible to have another thread with updated info including all the links to the files and tools in the first thread? I find this quite overwhelming when I have to bounce around to get the info and links needed to root the S7 Plus Tab running Android 12.

If you really want this then I suggest you create this other thread yourself. But I also think it would be overly redundant to have 2+ rooting threads.

BTW, this is the comprehensive method I use on my tab. It is exactly the same for 11 and 12 (can't say if it would be the same for 10, my tab came with 11 and no ability to downgrade). My steps will get you updated firmware, Magisk, TWRP, neutralized vbmeta, encryption disabled on the data partition. You can just skip the steps you don't want to do.

TWRP for the Samsung Galaxy Tab S7+ 5G (T976B)

I'm stuck in TWRP loop with the new T970XXU1ATK3 firmware won't boot to system after the update. Is there anyway to fix this issue?

I agree in not having two threads; however, the initial post in this thread needs updating. Personally, I think having a sticky post/thread which is always updated either by the mods/admins, or OP would be the solution. At least, that's just my opinion.

Well, the link I posted above works fine. It's my personal method which I've been using for months on both 11 and 12. It would probably work on 10 as well. The actual details of my method haven't really changed over the months. I feel that any Tab S7+ user should be able to follow my steps and get the same results as me. And they can just skip the steps that dont interest them. The only caveat is that I've only tested these steps with clean Android installs (wiping everything), not upgrades. I'm sure the steps would work with upgrades, but would need to be modified a bit here and there.

Just wanted to say thank you for your hard work and tolerance. My question @AnonVendetta is this effective for S7 SM-T870 of which I have and if so, can you give me a little more information when you mention flash TWRP? I can't seem to understand which TWRP to get that works for the S7 SM-T870 of which this forum is about.

there is no twrp for it, this forum only for rooting without twrp

Download the firmware, and extract "boot.img.lz4" from AP.
Use 7-zip or something else to compress the boot file and choose TAR format.
Use Magisk to patch the "boot.img.tar", and you will get "magisk_patched.tar" in /Download folder.
Flash it as AP and wipe user data. (You should unlock the bootloader.)
Then you have successfully rooted your device.
How to download the firmware.
Use Samfirm to search device model and CSC code.
It seems that Sammobile has not released the firmware of the new Galaxy Tab S7 series.
