Flash custom rom with triggered dm-verity - OnePlus 3T Questions & Answers

Hello. I want to know if it is possible to flash a custom rom with the triggered dm-verity or it is only a warning boot screen? Thanks

As far as I know, it's only a boot screen warning. I've flashed multiple times and I'm currently on asopa and it's only a an extra press of the power button (or extra 5 second delay) for me. It just means you aren't on 100% stock firmware. I can still pass safety net w magisk.

Ok thanks:good:

You can flash ROMs all you want. dm-verity doesn't prevent things from being flashed. It just triggers the additional dm-verity warning screen on reboot, if something is modified (namely, a non-stock recovery will always trigger it, I believe).
I flash ROMs with dm-verity triggered. No problem at all.

Thanks

How do I recover my nexus 6 from bootloop

Well this is my second time I am trying to install custom ROM on any android phone. First one was some cheap phone from local brand. And I ended up in bricking that phone. This time it seems I have boot looped beloved Nexus 6. :crying:
So now I know I have very poor experience with MODing stuff.
I decided to install latest lineage OS on my Nexus 6.
I followed steps given on lineageos.org tutorial:
Enabled developer options
Enabled USB debugging
Enabled OEM unlock from developer options
Installed adb drivers
Connected Nexus 6 to PC using USB
Selelcted transfer photos (PTP) mode on nexus 6 in the prmpt that appeared after connecting USB
Booted into fastboot by doing "adb reboot bootloader" command (I have my volume down button screwed up while replacing battery. Though there is no visible damage. I dont know what happened . So I was not able to boot into fastboot by holding volume down while mobile powers on. )
Downloaded TWRP and installed it doing "fastboot flash recovery twrp-x-x-x-x-shamu.img" command
The lineageos.org tutorial then asks to boot into recovery using volume down key. But since mine was screwed up, I didnt know how I can do that. So I fiddled a bit in fastboot mode and found that when I press volume up, there comes "recovery mode" option. So I pressed power button when recovery mode is shown when in fastboot mode. It successfully booted in TWRP recovery.
Then I tried to perform the backup from the TWRP. I used to get something "unable to mount..." error. I tried it twice/thrice. Then I booted into Android. I realized that I can run "adb reboot recovery" command to get back into the recovery. So I tried that but then I got No Command error. So I pressed and held power button for some time, it booted into android. I ran "adb reboot bootloader". When in fastboot, I pressed volume till it showed recovery option and then pressed power button to boot into recovery. Then I tried backup again and it worked this time. So it never worked when I boot into TWRP for first time. I had to boot into android and then again back into TWRP (through fastboot) second time for it to work. This pattern repeated for other things.
Then I tried to perform backup of system through TWRP. Somewhat similar thing happened. It was giving "Unable to mount..." error. So I boot into Android, then into fastboot, then into TWRP and it worked. I booted into Android and copy pasted those backup files on my PC.
Then I tried to perform wipe from TWRP. It again gave "Unable to mount..." error. So I again followed above steps. Booting Android -> Fastboot -> TWRP and then performed wipe (I wiped everything cache, system etc). It worked.
Then lineageos.org tutorial asks to put lienageos zip at /sdcard/ using command "adb push filename.zip /sdcard/". I guess I tried it in recovery and it was not working. Hence I selected to reboot in bootloader (or I guess System) from TWRP. (I am not remembering this last steps as I was noting down only those steps which worked in notepad which are explained till last point in this procedure. But I know I rebooted from fastboot after wiping) And thats where I screwed it up :crying: . Now only Google logo displays. When I long press power button, the Google logo diappears for a while and reappear. Irony is that my volume down also seems to be screwed. What options I am left with???
... mmh
I miss the step "fastboot oem unlock" between 7. and 8. (before flashing TWRP) to open the bootloader
Your step "3. Enabled OEM unlock from developer options" is just the requirement to open the bootloader!
You have to open the bootloader with the adb prompt "fastboot oem unlock" after booting to bootloader!
1. open bootloader
2. reboot system !!!
3. reboot to bootloader
4. flash TWRP (custom recovery)
my advice - back to start ...
please look here for the last factury image and flash the whole image as described

Select Transfer files.
When you boot after flashing LOS the forced encryption flag is set.
When the internal memory was decrypted.... the encryption process starts. Can take a very long time.

ohhh I felt its optional. I indeed do that "fastboot oem unlock" and it said it was successful. I just felt its optional and it did not had any effect on my phone, so I did not included that in the steps I performed above. Sorry my bad.

My phone is bootlooped (stuck on google logo). I am not even able to get into bootloader since my volume down key is screwed. I got screwed only after wiping data and before flashing LOS. Now I am trying to understand how your comment makes sense.

The possibility that the N6 is busy with encrypting and not looping (hopefully).
Other ideas:
When connected to a PC and adb environment is ok. Try the command: 'adb reboot bootloader'
Repeatedly while booting. In a dosbox it's easy to repeat a command with arrow up/down.
Keep start and vol up pressed and see if recovery comes up.
The screwed vol down.
Try to get a bit isopropanol/alcohol under the volume button to clean. Use a needle.
Instead of keeping the button down keep both vol.buttons down; maybe you are lucky.
Hi OP
May I ask:
if the bootloader was unlocked before you tried this time or stock with bootloader locked?
When you wiped did you wipe internal storage too or left it unchecked in TWRP?

I tried doing all that with volume button. Finally imported circuit fom ebay.com and got it working.
Was able to Install lineageOS 15.1 successfully, but the experience wasnt that smooth due to disabled CPU
cores. I tried installing elementalX on lineageOS through their official app. But seems that I am back again in bootloop. I asked
the detailed question here. Can you please have a look?

Trials with kernels and wiping/formatting may cause issues, because LOS forces encryption every time it's installed.
When you want to use LOS don't change the kernel and use the built-in kernel.
When the phone is not smooth, you may want to decrypt your Shamu and use a custom rom, like Nitrogen OS (Pie). A decrypted phone is necessary than.

Ok didnt get you well.
How can I decrypt? Any official link.
Also installing Nitrogen OS means wiping out LineageOS?
Also didnt get "A decrypted phone is necessary than".
Do you mean decrypted phone is what is needed.
Also does that means there is simply no custom kernel compatible with LineageOS 15.1 for Nexus 6? and I have live with only two cores?
Sorry for too many questions... ;\

A decrypted phone is only needed when you want to install a Pie rom like Nitrogen OS.
A new custom rom implies you will loose LOS.
There's nothing wrong with LOS, it worked well on my Shamu, but I used the built-in kernel and didn't care about the kernel and cores
For now. Try to get LOS working and use the built-in in kernel.
Decrypting your phone can be done with TWRP. You need to format everything including the sdcard.
But when you stick to LOS forget about decryption.

After watching some videos and some googling, I realized that its not about the kernel actually which turns off cores but its hotplug mpdecision. I installed kernel audiutor and enabled all cores of my Nexus 6. Also I realized that max frequency of my active cores were something 1958 MHz. I just increase it to max 2649 MHz and rebooted. My Nexus 6 is going super smooth now. Also ran geekbench4 benchmarks.
These are the benchmarks.
Before changing CPU stuff
================================================
Benchmarks 1
-----------------------------------------------------------------------------------------------
Single core: 593
Multicore: 997
After changing CPU stuff
================================================
Benchmarks 2
-----------------------------------------------------------------------------------------------
Single core: 818
Multicore: 1009
Benchmarks 3
-----------------------------------------------------------------------------------------------
Single core: 1069
Multicore: 3029
I feel that two cores were still offline during benchmark 2. When I checked after benchmark 2, they were off in kernel adiutor CPU monitor. I re-enabled them and I reran the geekbench. I ended up getting benchmark-3 which are quite good and in fact above average for Nexus 6. For 5-10 minutes now, all cores are active.
I then googled and realized that mpdecision restarts after every reboot. So I have to disable mpdecision on every reboot to enable all cores. Initially I was not getting meaning of two ON/OFF switches on kernel adiutor's interface. They were "Apply on boot" and "mpdecision". Now I have "Apply on boot" switched ON and "mpdecision" switched off. That means on every reboot, all my cores will be up at full frequency right?
Also that means more power consumption. So I have done certain things to compensate. Enabled dark mode so that Nexus's quad HD AMOLED will consume less power. Also installed Franco kernel's Servicely app which allows app and services to put on sleep when screen is off. I am also planning to use Nexis 6's always in battery saver mode. I am ok as long as it performs fast (with two core off, battery saver mode was useless, now it seems like very normal). Its just that only top and bottom orange bars/strips in battery saver mode annoys me.
One more thing I will love to have to save battery. In MIUI, there is per app setting for what to allow when app is in background as can be seen here: http://nine-faq.9folders.com/articl...-background-restriction-on-the-xiaomi-devices On my poco f1, I keep almost all apps "No background activity mode". Only handful have "No restriction". This is letting me extend battery to days straight. Is similar possible on lineageOS say through some apps or setting.
Also do you feel my config all fine? Latest lineageOS + All cores running at full speed + Power saving settings explained above? Is this perfect for performance and battery life? Should I disable encryption for further performance?
(Will be testing battery life soon for few days.)
(Just to add things implicit to me: I wont be installing any social media app on this, I keep data and location off always. I will be using Nexus 6 mostly for reading in chrome, pdf, word and youtube.)

I think you have done well. You've found the cause of performance issues and made your Shamu smooth again.
Dark mode is important for the battery life.
Decrypting will raise performance mainly when writing to internal storage. For daily use you won't hardly notice a difference. Your phone is running smoothly now. So there's no need for.

How to | Galaxy S9 (SM-G960F & F/DS) Root Android PIE

Exynos variants such as International (F), International Dual(Hybrid)-SIM (F/DS),
i am not responsible if anything goes wrong. You are still the one who tryed to flash the files. Even tough this should work as it worked for me and some friends.
Hello XDA
This is my first post (sorry if one already exists)
Today i am going to tell you how to root the Galaxy S9 International on android 9 Pie on stock touchwiz rom.
First of all download all these files;
Prince comsy odin: https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
Team win recovery https://forum.xda-developers.com/ga...cross-device-development/twrp-exynos-t3763464
ElementalX Kernel https://elementalx.org/devices/samsung-galaxy-s9/
No verity encrypt: https://androidfilehost.com/?fid=962187416754474353
Magisk 18.0 https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
Now for the root
First you need to unlock OEM, you can do this in developer options,
If there is no developer options you need to enable this
you can do this in: Settings>About Phone > software information > click 5 times on build number.
When you unlock OEM everything on your phone gets wiped so make a backup!!
When the wiping is complete, turn off your phone and go to download mode (Vol down + Bixby + Power)
Then connect the phone to your pc and start odin
In odin go to options, and disable f.reset and auto reboot.
Then press the AP button and select the TWRP image you downloaded.
When TWRP is flashed, force reboot your phone (Vol down+ Power) when it is powered off quickly press Vol Up + Bixby + Power to get into recovery
Swipe to allow modifications. And format /data
Then reboot into recovery.
When rebooted mount USB Storage and connect the phone to the PC
Then you can click&Drag the other files (elemental, Magisk, No verity)
When the files are on the phone, go to install and search for the files you just put on the phone.
Install in this order:
Flash No-Verity-Encrypt
Then flash the custom kernel (ElementalX)
And as last flash Magisk.
When you did this, you want to Factory reset, Wipe cache and Dalvik.
Then you can reboot the phone, and install it.
(It is possible that you stay at the boot logo for a long time (Not the galaxy s9 one but the next one) What you need to do then is let it boot for 5 minutes, then force reboot (vol down+Power) and then the phone boots fine)
Again, just to make sure check if OEM is still unlocked (sometimes this get locked again)
Please note that when you do this, you lose secure folder and other functions, also is the knox tripped (0x1)
But the Fingerprint, Irisscanner and samsung account works.
SOMETIMES IT IS NEEDED TO INSTALL THE MAGISK MANAGER MANUALLY, YOU CAN JUST DOWNLOAD THE FILE FROM THE LINK IN THIS POST
Hope this helps.
If you do have any questions, please do the following first;
Note any errors that odin or your phone gives you. I want to help you, but i do need to know what is going wrong.
(Sorry for my bad english)

So you won't need RMM-state_bypass on pie anymore?!? Seems hard to believe...
And why exactly you need to flash that custom kernel, which benefits does this bring with it?

If you dont use the custom kernel, you will get RMM error.
Iris scanner wont work, Fingerprint wont work, Samsung account wont work. When you reboot the phone you get a little "Bootloop" at the lockscreen (Screen flashes and is unusable and your pattern isn't saved)
I dont know what else breaks because i cant even get past the lockscreen with stock kernel
(Also you get better performace and battery life)
Hope this helps
work it with s9+?
Sorry for my English...
Yes, but you want to use tgpkernel then otherwise it will not work (problems described abovel
https://www.androidfilehost.com/?w=files&flid=288240
Last samsung phone i rooted was the note 3, and i remember that doing that "tripped" knox 0x1 and this basically voided the warranty. It's the same with S9? is there some non-reversible change that happens to the phone when rooting?

Yes, the knox will still trip (0x1).
In europe, when you can show that the root is not the cause of the problem, they have to fix it under warranty.
Also there are some functions you will lose (forever)
Knox,
Samsung pass,
Samsung Pay,
S-Health(you can fix this one with a build.prop tweak)
Secure folder
If you plan to use one of these (exceptpt s-health) It is better not to root your phone (there are still external app's you can use if you plan to root your phone)
Is there a way to update the stock firmware when you have root? Or do i have to do all over again?
I have this lock screen flashing bootloop issue, what is the fix? I have tried factory restores but get the same results once I set a lock/passcode and reboot. Samsung Account and Bixby also do not work as you mentioned.
You can use TGPkernel then,
Some phones have this issue, some not.
I have seen that 3 friends of mine it worked, and also on 3 not, so this is a very weird issue
What was the fix with them is to install TGPkernel
@co9
The only way i know is to install a custom kernel,
Otherwise you have to download latest stock rom, and flash this using odin.
wich changes your recovery.img and boot.img, aswell as the kernel. so you have to flash this all over again
Thanks for the answer. I already have a custom kernel. So if i always want to have the latest Samsung firmware i have to flash it through odin and do the whole root procedure again?
I tried this method but now everytime I reboot the phone my bluetooth paired device are lost. They also get deleted if I turn ON and OFF the Airplane mode. Anyone else having the same issue ?
Is anyone else experiencing an issue where the password, pin, or pattern set before setting up fingerprint scanning acts like what was entered is incorrect, not allowing you to setup fingerprint scanning?
I've tried setting up fingerprint scanning on initial setup as well as skipping and trying after the phone has been setup but had no luck. What ever I set initially will not work when I'm prompted later on when trying to setup fingerprint scanning or tying to access other secure features. The phone just prompts to try again acting like I entered in the wrong password, pin, or pattern. I've even tested by setting up a REALLY simple password with no luck.
I have confirmed in the settings that Elemental is installed.
Edit: I did find this thread https://forum.xda-developers.com/galaxy-s9/help/root-galaxy-s9-exynos-9-0-android-pie-t3884267. I tried the no-verity-opt-encrypt-6.0.zip that was suggested in some posts but had no success. I've also tried the TGPKernel but had not change in the issue. I am able to setup fingerprint scanning on fresh firmware install but after installing TWRP and everything else the above issue happens.

Don't root this phone without flashing a custom kernel or a modified stock kernel. It will drain battery and reduce the performance or even crash the system.
Look in the TWRP thread there it is explained why you shouldn't do it.

Hi all,
I tried to flash twrp but never succed.
S9+ last firmware from samsun android 9 pie (update from smart switch)
Then option developper activated, no oem unlock menu found,
boot into download mode and there is written oem unlock desactivated so ok
with odin try to flash (ap, reboot freset unchecked)
then fails and message in red on the phone :
"only official released binaries are allowed to be flashed recovery"
History :
I was in galaxy project oreo, i wanted to upgrade with pie, but reboot cycle
so rescue with odin and original oreo firmware, then update to pie
thanks for help
regards
To get the oem unluck button visible.
After fresh install, go to time/date in settings, choose manual and set the date 1 mount prior (march will be februar)
Than go to software update, choose manual en click on dowload updates manually.
Restart your phone and the oem unlock button in developer options will be there
Cheers
thank's for answering,
Update done, reboot ok but still not oem options in developpers section

How to root the tablet A8 2019 T290

Hello guys, decide to mount this tutorial because I still see a lot of people with doubts, yes we already have how to root our device
I did it on mine and it worked, do it at your own risk, neither I nor anyone else on the forum is responsible for any loss
A tutorials too complex for some users, teaching you how to create your own Magisk modified Img boot, but I like simplicity, so if you don't want to break your head too much, here's a tip, use a successfully modified img boot , what you need is to install the rom stock that was used to create the modified boot first.
let's go to the tutorial, warning that the files posted here are not my own, and if it doesn't work, check if you're not commenting on any flaws, don't try to memorize the tutorial, follow it step by step. come on!:dedos cruzados:
1 - first follow these steps to unlock the bootloader:
This is a basic step to root device. Go to settings - about phone - Software Information - tap multiple times on "Build number" - This will open developer option.
Now in settings at the end, you will have new option "Developer options" - look for OEM unlocking - Enable it.
(PS : If you don't see this option then you may need to wait up to 7 days or more to appear or may be on some operator you will get it never. Without this option you can not root your device, sorry!)
Once you have enable OEM unlock option, switch off your device and reboot to download mode.
To put device in download mode - Press Volume Up & then Press Volume Down (Keep holding both) and connect device to PC with USB cable
When device start to download mode,long press volume up to unlock the bootloader. This will wipe your data and automatically reboot
Now let finish setup and again enable developer options (as said above), and confirm that the OEM unlocking option exists and grayed out!
If it is not then you can not root device!
Once you see this option and greyed out, you are ready to flash custom binary and root your device.
Now let's go to the next step, reinstall an outdated system, I did it on mine and it worked, do it at your own risk, neither I nor anyone else on the forum is responsible for any loss
2 - installing the stock ROM that we will use:
download this rom: https://samfrew.com/ru/download/Gal..._Wi-Fi-__/rue3/KOO/T290KSU3BUE1/T290KOO3BUE2/
OBS: a little detail about this firmware, it is made in arm32, which apparently makes it "lighter", but also has a more acidic use of RAM memory. This was the last software I installed on tab A, and I can say that the use has become better with it, but if you want to stay in the stock rom, even custom gsi didn't get such a good performance. It's worth testing, but be aware of the risks, I'm not responsible for errors.
Updating: use a modified version of Odin, to do the installations, be careful with downgrades, I managed, I was in the most current version of March, and I managed anyway using this modified Odin, but do it at your own risk, download the most current version here:
https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
And install via Odin, if you need more details just a Google, there are already millions of tutorials for that lol
when you get here you should already be aware that you have lost all your data, but it is necessary that the OEM option is enabled in the options, so in the CSC session use Home CSC, so that you leave the data saved, and do not lose the initial settings : )
once with successful installation, we will now install the file modified by magisk
3 - magisk Installation:
Intall TWRP: https://forum.xda-developers.com/t/...-2-for-2019-galaxy-tab-a-8-0-sm-t290.4185235/
just follow our friend's tutorial, with a little observation, after starting the process in odin, be sure to hold the volume up button + turn on, to be redirected to the TWRP.
follow the standard steps to install magisk, if it doesn't work, you will have to manually modify the system boot.img along with magisk maneger.
if case of problem:
The process of entering recovery on the SM-T290 using buttons is really finicky, unlike the 10.1" version. My best result has been with holding Power + Vol Up on startup, quickly switching to hit Power to dismiss the bootloader unlock warning page, and then immediately holding Power + Vol Up again for 6 seconds. (Holding longer will cause a hard reset.)
If you miss on the first attempt and haven't installed Multidisabler, it will revert your custom recovery to the stock OEM recovery.
I haven't had the tablet in my hands for a few months, so unfortunately I can't help more than that, as I said this was the last system I used, just because GSI are not very functional and are not always light, sometimes they crash more and it has more annoying bugs to fix that discourage daily use. my tip is, stay in stock Koo, excuses for those who can't, the most I can do now is guide them.
As a gift for you, I will teach you how to use Xposed :3
remembering, I did several tests that several times I faced bootlooops but in the end it worked for me, so notice, do it at your own risk.
5 - How to install end use EDexposed with Magisk
these versions were the ones that worked without problems in this rom
Install Riru - (Riru core) V21.0
Install Riru - Edxposed v 0.4.6.1(4510) YAHFA
Reboot, after reboot, install Edxposed Manager
and you can be happy
I thank you all for your help, and remembering that this was just a compilation of tips, to facilitate everyone, take due care to avoid problems, and don't forget to thank: 3 ?
Has anyone attempted this yet?
I am attempting to apply this root and I have run into a minor issue.
The AP Patched file from magisk isn't compressed correctly. Maybe I don't understand, but using 7zip, i can see that all the compressed files inside the AP file are LZ4's, but after patching with magisk, some become .IMG and odin errors our whenever I hit modem.Bin.
Any Ideas?

Hi friend, sorry but there are more current ways of routing, even already working on a TWRP, but now you can do the following, try using the same Firmware in the same version of the bootloader, otherwise there will always be an error, the file compressed this modified to work with Odin, I tested it myself on my T290, but I cannot guarantee its effectiveness if I try to use it in another version, I do not recommend doing this even.
I had trouble unlocking the bootloader until I did this:
After enabling OEM unlocking and turning the device off, plug in the USB cable. Hold both Vol + and Vol - at the same time, then unplug and replug the USB cable. The bootloader unlock screen should come up.
I posted this on twrp thread, but seems no one wants to answer , thought give it a try here?
Anyone know of a fix for the blank screen?
Not sure why they would lock down this tablet but not others?
Whats the point of unblocking the bootloader if you can not do custom roms , root etc?
My firmware is on T290XXU3BUC1
I can successfully installed twrp via Odin.
I reboot, instantly blank screen. I have rebooted into twrp with blank screen.
I was able to install the nexus rom, with adb twrp command line and works but all is blank screen.
I go back to stock and the display is back.
I have tried another twrp on this forum but that gives me security error.
I have also tried to patch ap tar with Magiskt but that flashes but when restart get security error.
Twrp is the only thing that works but complete blank screen with back light.
Tab is unlocked bootloader and oem unlocking on.
does this work if you're on a11?

what are you specifically asking? the TWRP here is very functional, but custom roms are not very stable for this tablet, some GSI behave well, but it's still better to stock debloated

Hi, maybe you can help me.
i rooted my SM-T290 MXO with Android 10 but the system always asked me about a new patch update (May 1 Update) and i dont know how to apply updates so i downladed the firmware update via ODIN, long story short after applying the firmware and updating trough Smart Switch (because now my tablet say that the SO has been modified and now i can´t update trought OTA) and now i have Android 11 with One 3.1 so my questions are:
Can install TWRP like before in his version of Android?
In case i need to downgrade to Android 9, do i need to be the exact carrier (XAR = United States) in the file you put or should i use my carrier (MXO = Mexico) and is the same result?
I hope anyone can help me because i dont know much about rooting and is the second time im dealing with rooting a Samsung Device (My first attempt was a Galaxy 4 and was frustrating that KNOX detected my bad root)
Thanks in Advance.

yes, you can go back to previous versions, but it gets harder when you upgrade bootloader version.
In order not to crash the downgrade, you need to look for the latest Android version you want, from your region you are in now.
An example:
I'm on the latest version ZTO - Brazil - Android 11
to get back to Android 10 I need to download the latest ZTO version with Android 9, of course you can try between different regions, but it will be a little more complicated.
Hello
I was asking, how do i root this thing lol, it has been a nightmare
I can not root with custom magisk patched rom, as get boot error, and i can install Twrp, which works, but i just get a blank screen.
Was wondering if there was a work around?

You mentioned it's on Android 11, didn't you?!
well, I don't have Tab A with me anymore, but the suggestion I give you is to try to go back to Android 10, then install TWRP, and then try to install magisk, I can give you the last firmware I installed,
currently he is with my brother.
The firmware is Koreano, as I said, it is 32bits, and super functional.
Samsung SM-T290/T295 Galaxy Tab A 8.0 (2019) - Прошивки - 4PDA
Samsung SM-T290/T295 Galaxy Tab A 8.0 (2019) - Прошивки
4pda.to
take a look here, search for the firmware I told you about, very good by the way
Hey
I am on T290XXU3BUC1 and i do not understand the language on the link you post
I tried your tutorial , but i am getting
sw rev check fail [aboot] Fused 3 > binary 3
hello, about that, but lately I don't have much time, but I'll update it today if I can, you probably got this error because this firmware is old.on 4pda there is a newer version with root, remembering that currently you can root through twrp, I'm going to port my last attempts here, but I notice that I don't have the tablet in my hands. use translation tools, the site is in Russian
I updated the guide as I could, any doubts I'm still here, but I can only guide, it's no longer possible to test.
Thanks for the update. The only problem is, is that i have the newer tab and when I flash TWRP, i get a blank screen
I need a way to patch the firmware without failing, as i do not think anyone is trying to fix the blank screen bug with TWRP, unless they are on 4pad.to , but no idea due to the language barrier hehe.

have you tried to put the firmware I mentioned? this tutorial probably won't work on android 11 one ui 3.1, i say this because the TWRP is a bit old, so as long as it's on the updated firmware it's really hard to do anything.
if you don't want the specific KOO Firmware, you can get the latest firmware version for your region which is on android 10.

[Question] regarding installation of Magisk from recovery

Hi,
Please indulge me if this it a bit silly, but I am confused about installing magisk from recovery. I flashed the patched image to recovery partition, as per the github guide (https%3A//topjohnwu.github.io/Magisk/install.html%23boot-image-patching, sorry for the encoding, system forbids me to post link cuz I am new). Yet at this point I am unsure about what to do next. This is what I see now when I boot my phone to recovery using key combo:
- Reboot system now
- Apply update from ADB
- Apply update from internal storage
- Wipe data/factory reset
- Wipe cache partition
- Mounts a storage
If I select "Reboot system now", nothing seem to happen and it all looks like a normal startup.
In short, I would like to know how to run to a ystem with Magisk enabled.
Thanks in advance!
You're not actually supposed to boot to recovery. You need to release the key combo once you see the splash screen. Reference:
https://topjohnwu.github.io/Magisk/install.html#magisk-in-recovery
Edit: and don't worry... Everyone's a noob at some point or another.
Didgeridoohan is right: It sounds like you're booting into your phone's stock recovery, instead of your custom recovery.
Forgive my presumptions, or if I sound condescending, but if you happened to have patched and flashed your partition mods with a PC, you might want to check if you even have a custom recovery installed. (I know that some phones aren't capable of having a custom recovery flashed, so your situation might be different.) If you don't have one, that would be the first step (most folks use TWRP). Once you can boot into your custom recovery, though, you should be good.

Right, this is the part where I get confused. I did follow the link you mentioned. After pressing [power] & [volume up] for about 8 seconds, I feel a vibration and the screen lights up, thats when i released the keys. I ended up getting that menu i describe above...(tears)...
Ideally, what should I see if things go right?

No worries. Any suggestion is much ppreciated. Just to be sure (correct me if i m wrong), I thought that patching an image file is an independent way of installing magisk in case custom recovery is not available. So that s my case.
Anyhow, I would really like to learn a bit more about the situation where recovery partition contains both the stock recovery and custom recovery/patched image. There doesnt seem to be any difference whether i release the key combo or not once I see a splash screen. I always end up with that blue menu in recovery.

If you don't mind my asking, which model of phone do you have? Most phones have a similar button combo, but are a bit quirky to get into the recovery.
Ex: On my LG V20, I have to hold Vol-, and Power, but release the power button at the splash screen for 0.5-1 seconds (while still holding Vol-) and then press/hold the Power button again...
As a suggestion, you may want to see if your phone has a similar quirk, depending on the make /model.

[Solved] by flashing boot image instead of recovery image
I am still puzzled by the complications with booting into recovery mode. To work around it, I attemped installing Magisk using boot image patch and succeeded. Objective achieved yet question remains. Anyways, a big thanks to Didgeridoohan and NeoHiPPy1980. Knowing that someone will provide help is what stopped me from giving up.

I have a Ulefone, not sure if you ve heard of it
But that won't matter. I managed to get it working another way (see to my last post). I should probably have done that before making this post. Thanks for your assistance!
Great to hear you got things working, but why did you think you needed to use the recovery image for your device? Was any of the installation instructions unclear and in need of improvement (I'm just trying to learn for future reference)?

Frankly, I find the Magisk Installation Guide to be one of very few documentation that is concise, coherent and user-friendly for both regular user and developer. So a big thumb up for you all! For your reference, here is the process of how I was lead to believe I needed the recovery img:
1.
I followed the instruction on "know your device" (https%3A//topjohnwu.github.io/Magisk/install.html#knowing-your-device). The first command returns nothing and the seconde comand returns true. Naturally, I assumed this means that my device is using system-as-root on a non-A/B device.
2.
I then read:
If your device is NOT A/B, but IS using system-as-root, then you will have to install Magisk to the recovery partition of your device. Follow the instructions in Boot Image Patching, but instead of using your boot image, use your recovery image. "

(https%3A//topjohnwu.github.io/Magisk/install.html#getting-started)
I am not sure if I misunderstood sth. At this point I still believe that according to the instruction I should have patched my recovery image. I do not know what system-as-boot actually is...
Yes, it does seem like your device is A-only system-as-root, which would normally mean you need to use the recovery image.
Unfortunately, with the Android ecosystem being as fractured as it is there will always be exceptions...
Thanks for the detailed response.
Hi Guys
Wubwubdubdub, I have got a question for you. I followed the same instructions as you mentioned in first post and ran into problems as well. How did you get around this problem? What is the difference between the two ways you mentioned here? (I believe I used the first way).

Help with "semi-bricked" Galaxy s10 / fingerprint spoofing fail

Hello everyone. Excuse me if this is not the correct place for this thread.
I have a samsung galaxy s10 (eu model) rooted with magisk. Installed props module and changed all fingerprint parameters to match a samsung tablet.
Now, when I reboot the phone and activate the root/magisk ( side button+vol up+power ) it starts booting and after some time dies and reboots (on the "samsung" screen). If I just leave it without trying to load magisk, the phone boots fine, but the root is not available. So I guess there is something in the spoofed fingerprint that causes the boot issue. Unfortunately, without loaded magisk I can not disable/edit the props module.
So, is there a way fix this (get a working rooted phone) without wiping and flashing again the phone?
Thanks in advance.
p.s.
Nevermind, for deletion. After few attempts to fix this I had to reflash the rooted firmware.
