Updates.

I was on stock firmware with root.

I downloaded the latest version of twrp, patched it in recovery.img, converted to recovery.tar.

From odin I have installed BL, AP (with recovery.tar), cp, csc and homecsc.

Something is wrong because the phone only starts in downloadmode with the words:

recovery: error validating footer. (0)

recovery: error verifying vmeta image: invalid vbmeta header (6).

custom recovery g975fxxu9dtja, 35343968a

---------- Post added at 11:50 AM ---------- Previous post was at 11:44 AM ----------

I had omitted this factor.

Download avb disabled vbmeta .tar

Open Odin v3.14.1 and place the downloaded TWRP .tar file in AP tab, downloaded vbmeta .tar file in CP tab and click Start - once you press start grab the phone and press vol up + bixby + power to force it boot straight in TWRP after flashing.

So, now I got the recovery, and flashed the multidisabler.

We hope well.

nada...

i'm stupid or what?

i deleted everything, redid root with masigk (ap patched).

I patched the recovery, flash in AP with vmbeta in CP, bl with the original bl and csc.

I have twrp recovery but the sartphne does not start .. bootloop on the samsung logo.

What am I doing wrong?

---------- Post added at 01:22 PM ---------- Previous post was at 12:58 PM ----------

after doing all of the above, i had got a bootloop.

Sure I have done everything accurately, I tried to make a "format data" confirming with the writing YES from recovery.

At that point I flashed the multidisabler.zip.

I rebooted and finally the phone booted normally, I followed the first boot, language, date and time, etc ...

Now I have installed magisk manager again, from which I got the root (magisk has configured the rootm by rebooting the phone autonomously).

I finished? I have both root and recovery. All right? Can I use the phone and in this case, if I now perform a full backup from twrp recovery, would a subsequent restore from twrp bring me back to the conditions I am in now?

Also, can I use terminal disabler (magisk plugin) now ?.

Thanks for the tips.

Hi 😊

Does it have toybox/busybox built in or can I go ahead and flash the busybox magisk module?

Kind regards
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] corsicanu:
Those are only working in recovery. If you need busybox inside the system you have to flash the magisk module of choice containing them.

good Morning, a noob question please.

Let the phone boot normally, pass the setup and connect to internet (wireless or mobile data) in order to unlock RMM;

Make sure OEM Unlock is ON in developer settings;

Turn off the phone;

Use vol down + bixby key + usb cable plugged to a pc to start the phone in download mode, short press vol up to confirm you want to go to download mode;

* If by any chance you see RMM state=Prenormal or KG state=Prenormal, redo from step 5!

What is RMM?? Thanks in advcnce
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] Philnicolls89:
RMM is a security feature that stops you from flashing any custom binarys through odin (roms, TWRP etc).

Hello! I'm new to android ROMs. I'm attempting to flash LineageOS alongside Magisk. I tried this a few months back but due to some hardware issues I needed to return the phone and order a new one. Here I am, at it again.

So I came to the XDK forums and found the LineageOS 18 thread and started following the instructions there, as well as these recommended TWRP thread instructions. In this TWRP thread I clicked the download link for S10+ and the instructions said to first root with Magisk, then pre-root a TWRP image before flashing it to recovery. It linked me to the john wu instructions. So these are the instructions I've followed:

Make sure OEM unlock is on

Turn phone off

Boot into download mode

Flash stock firmware (obtained via Frija, version G975FXXS9DTK9 / SM-G975F_1_20201116171140_gnww4vsynz_fac zip.enc4

Repeat 1-3

Long press volume up to unlock bootloader

Repeat 1-3

I then followed John Wu's instructions available here. My phone's ramdisk result was "no", so I skipped to the Samsung System as Root section.

Unlocking Bootloader

This was done previously, so I read through it but ended up skipping all the instructions. I confirmed that in dev settings the OEM Bootloader option is greyed out and set to "on".

Instructions

I followed all of these. Once Odin3 finished flashing the Magisk patched AP file my device rebooted. It is now stuck in a bootloop.

After arriving here, I did some googling and got my phone back into download mode, then reflashed the stock firmware. The device boots properly into the Samsung setup screen and now will gracefully boot once shutdown.

What did I do wrong? Why are these instructions so unclear?

Thanks in advance.

EDIT:

So I took a break for a day, and looked up some further guides and reading. I reflashed the stock firmware after trying the above process again, then followed these instructions. I got as far as step 10 (and made sure to untick "auto-reboot" in Odin3), but during this process my phone got stuck in a boot loop AGAIN. reflashed with stock firmware AGAIN. I have no idea why this isn't working, some help would be greatly appreciated since apparently this isn't as straightforward as following the simple instructions from one of 3 or 4 different guides that all say the same ****. Before anyone asks, when I flashed the magisk-patched file, YES, I also added in the stock BL, CP, CSC files (CSC, not HOME_CSC).

quick concern - in backup

As I try to make a nandroid backup I noticed that system is not available.
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] Philnicolls89:
The steps to install root (magisk) are quite simple, so I'm not sure why it isn't working for you. Just to clarify these are the steps you took:

1. Unlock developer options and turn on OEM unlocking.

2. Turn off phone, boot to download mode and unlock boot loader. This will do a data format (wipe everything on ur phone)

3. Turn on phone, set up phone and install magisk manager

4. Download firmware from frija or sammobile

5. patch the AP file with magisk

6. Download the correct twrp for ur firmware and patch twrp with magisk (different TWRP versions are needed for different firmware versions)

7. Rename patched twrp to 'recovery', then open patched AP file using 7zip, replace stock recovery with new recovery file

8. Flash AP file using odin along with the other bl,cp and csc or home_csc files

9. Restart to twrp using key combo and flash multi disabler

10. Using twrp select restart to recovery and allow phone to boot

11. Open magisk manager, magisk should now be installed or ask you to finish the set up process.

12. Enjoy

This is a basic guide and if its what you already did and are still experiencing bootloops please let me know and I'll point you in the right direction.

Once u are rooted with twrp you can then go about installing your custom roms etc.
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] drinks_rootbeer:
Yep, so far so good.

Hmm, that doesn't look familiar

Must have missed this part too . . .

Alright, looks like I missed a large chunk of the instructions somewhere. I'll give this set of instructions a try and see how it goes!
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] Philnicolls89:
You can also just root with magisk and stock recovery. Then once rooted use flashify to flash your patched twrp image (renamed to recovery of course).

I have never used this method though as flashing twrp with the rest of the firmware is just as easy.
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] drinks_rootbeer:
So the first set of instructions you posted is still not working for me. I'm able to get everything sorted and boot into lineageOS, but once I reboot I can't get back into LOS? I know I've read about this being an issue before so I'm trying to track down the solution right now.
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] Philnicolls89:
Seems like it has something to do with lineage, have you tried using stock os just to see if it works properly or not? Then if you can narrow down the issue to say LOS or magisk or twrp, then you can ask for advice in the corresponding thread.
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] drinks_rootbeer:
Yeah, when I flashed stock firmware in the past I'm able to boot/reboot/shutdown->boot into samsung's android OS just fine.

As for TWRP with no LOS, I don't think I tried to reboot into stock Samsung android OS. Each time I have completed installing TWRP, I reboot into "recovery" to boot up rooted/magisk android first, then I shut down and boot into TWRP to flash LOS. I'll try jwiping, re-installing TWRP and testing to see whether the "recovery" partition is stable then.
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] Philnicolls89:
At least you know its a lineage issue, I don't have any experience with lineage specifically so am unsure. I would try asking in their thread, perhaps they have certain install instructions that you need to follow for that particular rom?

I installed A11 (AUT) this morning. Installed TWRP Imcd, Magisk 21.2 but got no root.I tried Corsican's TWRP but version 3.4.0.2 because I didn't know it was newer. After many tries, I gave up and went back to the A10. It's a pity that I didn't know about this version then and now I'm discouraged and don't want to start over without confirmation.

Seems like last version supports android 11 , maybe some one tried the last one ?
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] hanspampel:
There are no kernel sources out yet for A11. So the latest twrp shouldnt work wih A11, but didnt test it, maybe it works. Normally we have to wait for kernel sources from samsung. Atm there are only 2 FWs available, so i think we have to wait 2 or 3 weeks till the sources come.
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] hanspampel:
I answere myself. Patched the latest TWRP, build my own A11 ROM and it seems to work. But didnt flashed the latest BL yet. Camera works with the TWRP, not sure if it will work wit A11 BL etc.
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] __Michael__:

For sure. Otherwise you dont get root if you dont patch the twrp.img. There are no kernel sources out yet, so the only way to root your phone is, patch the recovery.

Latest version breaks WiFi for SM-G970F on DTK9

Hi corsicanu,

I noticed that installing the latest versions of TWRP for the SM-G970F on firmware version DTK9 breaks WiFi. I have tested this with versions twrp-3.5.0_9-0-beyond0lte & twrp-3.5.0_9-1-beyond0lte respectively. And after that WiFi is disabled and can't be turned on. This was tested on version G970FXXS9DTK9 with magisk 21.2, 21.3 & 21.4 patched.

Unfortunately I couldn't get logs for the issue. But if you insist, I could replicate the process and give you the logs you need.

I am currently on twrp-3.4.0_9-3-beyond0lte with DTK9 and magisk 21.4 patched. work fine and no issues.

Thank you
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] AndrzejDwo:
No wonder 3.5.0_9-1 breaks WiFi on Android 10, it is made for Android 11... Weird that it booted and the rest was fine...

3.5.0_9-0 worked fine for me on DTK9 and DTL1 G975F.

Cheers
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] xdagee:

Android 11 TWRP is up already for a while, in case you didn't notice it yet grab it from twrp.me.

Don't forget to use targeted TWRP for your android version and release, read more about compatibility in second post of this thread.

So basically to the release dates and twrp version numbers to use

twrp-3.5.0_9-1 - 08.01.2021 - android 11 support - Compatibility: only ETL* firmwares, OneUI 3.0

twrp-3.5.0_9-0 - 27.12.2020 - android 10 support - Compatibility: only DTK* and DTL* firmwares, OneUI 2.5
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] jelbo:
Is this build using the S10 Android 11 kernel source? I read that's necessary to be fully compatible. Right now I switched back to stock recovery because of that idea.

Yes.
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] jelbo:
Great. I switched back to TWRP. I patched twrp-3.5.0_9-1-beyond1lte.img using Magisk Manager and the 'Recovery Mode' option ticked. Then I flashed the output file using the TWRP app.
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] Knowbody42:
I have a G973F, and I've unlocked the bootloader and attempted to flash TWRP.

I put it in download mode, and in odin set AP to the twrp tar file, and CP to the vbmeta tar file, and flashed.

But after reboot, it just gets stuck on the Samsung splash screen with red "The phone is not running Samsung's official software" at the bottom.

It won't seem to let me boot to TWRP.
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] xdagee:
If you see/get that red text is not a problem.

Now to boot into TWRP, you need to continuously press the key combos until TWRP shows up.

After installing Magisk in recovery (starting from power off):

(Power up normally) → (System with NO Magisk)

(Recovery Key Combo) → (Splash screen) → (Release all buttons) → (System with Magisk)

(Recovery Key Combo) → (Splash screen) → (Keep pressing volume up) → (Recovery Mode)
[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] Knowbody42:
Basically, it won't boot to the main OS any more, and it won't let me actually power it off fully.

It will reboot with volume down + power button (or Bixby + volume down + power button). And I have tried to boot to TWRP by quickly switch to Bixby + volume up + power button, but that still won't do it.

It will reboot to download mode if I plug in a USB cable, reboot with Bixby + volume down + power button, then release power button.

[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] xdagee:
The key combo for TWRP / recovery mode is volume up + bixby + power.

on reboot you press the key combo, you keep pressing until you see TWRP / recovery then you can release.
