[Magisk] Root for the Galaxy S10 Series

[sperelli]

I've lost track of what you've been told. You need to read a substantial amount of this and other threads. What I've seen was probably in the T290 and T295 threads, but I'm not sure.

I think some people said using adb to boot to recovery triggers Magisk.

It might be that having a USB cord plugged into the device (not necessarily connected to a PC) helped.

The most useful thing would be learning what signal to respond to by releasing the buttons. It's not random, and somebody described it well enough for me to do it.

What kind of reboot are you talking about? If from a running system with Magisk, there's an option in the Manager to reboot -- that ends with Magisk again. If Magisk is not active, maybe there's a "boot to recovery" option in the Power menu. (Maybe there's a Developer option that adds Recovery to the power menu.

Mostly, you have to read a lot and try a lot of things.

Do you expect to have to reboot a lot?

i was asking about the simple reboot (not to bootloader or recovery). i read it needs a combo to be performed, correct?

If Magisk is installed in recovery, then to reboot Android and have Magisk active you go through the motions of booting to recovery -- to run the code in which Magisk has been embedded -- but you need to release the buttons at the right time, so that when Magisk "becomes aware" and checks the button status, it will conclude that you are no longer holding down the buttons, and so it will choose to boot the Android system. (If Magisk decides that you are still holding down the buttons, Magisk will turn control over to the "recovery".)

Having said all that, I will now tell you that after installing Magisk in the recovery of my SM-T290, and after booting many times until I hit that magic spot where I got the tablet to try to boot recovery, but I got Magisk to realize that I didn't really want recovery, so I got Android running with Magisk active -- since that time, I can shut down my tablet, and then reboot by holding the power button, and when Android boots, Magisk is active.

I don't know if something special was done to Magisk between the time the installation instructions were written and the time I downloaded a copy of Magisk.apk. I don't know if different devices behave differently. As I said, I think I've seen people report being able to boot Android with Magisk active without the tricky key-combo-and-release dance. I tried to describe what I remember. I tried to describe where I probably read it.

TL;DR The tricky key combo always works. The tricky key combo may not be necessary.

Hi Guys, I have S10 plus rooted via Odin3 for at least 3 years, everything was alright, safety net check, Magisk hide, etc.

But unfortunately I ended up clicking up on the APP update button(only) and got the 25.2 version installed, the app worked well after that but then I realised that Magisk hide was gone on that version.

After that, I pressed uninstall and then installed the version 23 with the same apk I had from the original root and now I can't make it work, even turning phone off, plugging the cable at my laptop and using holding bixby, vol down and power button as I used to do before.

Did I **** the root somehow?

Do I have to do all root process again?

Am. I going to lose data?

If a good soul can help me this would be much appreciated as I don't have much knowledge at this...

Thank you

Yes, you screwed up something.
You do not say what version of Magisk you had when everything was fine.

You need to explain in detail how you tried to fix it: Did you still have the magisk-patched-AP.tar from 3 years ago? Is that what you flashed? Have there been any system updates during the 3 years?

If, by uninstalling, you mean you uninstalled the Magisk Manager app and reinstalled the 3y old manager apk, you did not uninstall the Magisk embedded in your [boot, recovery, I don't know which]. I expect a new Magisk to be unhappy with an old manager.

Please confirm that the updated Magisk was working fine before you tried to revert the update. Then explain exactly what you did to revert.

Maybe hold off on trying the next six random things that pop into your head until someone has a chance to advise you.

I think it would be safe to see if adb can recognize your device, and if adb shell gives you the ability to list ("ls") any files.

Sorry, I forgot to give more details...

I had Magisk 23 and everything was fine, then I hit the update button at the APP section only and installed the version 25.2, after the update the root was still working with the root at version 23 and app at 25.2, but as I mentioned, I realised the version 25.2 doesn't have magisk hide and decided to install 23 again.


Then I went to the app and pressed uninstall/restore image and then complete uninstall. After that I went to the 23 version apk and installed it again but now the root is gone.

I still got the "AP_G975FXXSBFUF3_CL21644994_QB41014117_REV01_user_low_ship_meta_OS11.tar.md5"
In my ad card and all files I have used to root it 3y ago and I have never updated the phone.

Thanks mate.

Now you say "the root is gone". Does that mean Android boots fine but you no longer have Magisk installed?

That makes sense, you hit "uninstall / restore images".

I don't know if you are going to lose your data. Back up what you can, or what you care about.

If you really have all the files from 3y ago -- AP, BL, CP, CSC, magisk-patched.tar -- the easiest thing to try is run Odin, giving it magisk-patched.tar, BL, CP, and one of the CSCs. Please READ SOMEWHERE ELSE to figure out which CSC will NOT wipe your data -- I don't trust my memory.

With luck, that will put you back where you were.

A lot of things can go wrong. Some versions of Magisk downloaded the latest as part of the "more setup", you have to set the update channel in the manager, and for a "custom" version -- meaning not the current version -- you need a URL to a JSON file that then points to the right archived files. I think more recent versions of Magisk are self-contained, but I don't remember the version number.

Maybe disable your internet connection before booting to download mode to run Odin.

Maybe wait to hear from someone who has done this more recently than I have.

@J.Michael sorry for the late reply, I got very sick and had to leave this behind.

Anyway, thank for you time sown and help

I haven't tryed yet, I think will do this weekend.

The CSC I remember is the "HOME" version to not wipe the data and keep the phone as it is.

My only questions, that can be a bit stupid is:

Should I install install the magisk apk I had at that time again(3y ago version) , and then patch the firmware(3y ago version) again to get the magisk-patched.tar from phone the way it is now? Does it make any difference erence?

Or by using the same magisk-patched.tar I had 3y ago, and Home CSC my phone will keep the way it is now?

If you are sure you have not updated since you successfully installed Magisk 3y ago, you can use the magisk-patched.tar you made and used 3y ago.

I do not know the rules for using HOME_CSC to avoid wiping data. The installation instructions for Magisk specify reformatting /data between flashing Magisk and the first boot. You might be able to skip that if your /data is already unencrypted. I don't know.

Maybe you should try to find posts from people with your device who have tried to install more recent versions of Magisk. It is possible that the rules have changed.

100% success

I ran Odin with all my files from 3y ago and used HOME_CSC and everything went well.

Magisk 23 running again on my S10plus with Android 11.
