Root with Magisk plus TWRP difficulty. - Samsung Galaxy Note 10 Questions & Answers

There doesn't seem to be correct directions available on how to root and install TWRP. There are directions to install TWRP, there are directions to root with Magisk, but not both... at least that I can seem to find.
So I am having some difficulty figuring out how to root my Note 10+ 975F. I can get it to root following the instructions, firmware AP patch with Magisk, copy back to PC, flash with Odin. Hold power+vol up till 3rd splash and it boots right into rooted OS.
Then when I install TWRP (using official TWRP app) I cannot get back into rooted version. Magisk is always N/A no matter how many times I try the button combo.
I'm wondering what I'm doing wrong? Any ideas or links?
Edit: Android R (11)

Ramified rom failing to install /flash

i Go through all the steps but when i get to step 6. it neither the TWRP or Root are installed. Odin goes through he motions and says pass but after reboot there is neither a root or TWRP to be found. My phone is a Galaxy S6 SM-G920P
All what steps? Is your phone rooted already? Did you have twrp before?

Any root for SM-J327W yet?

Hello, I was searching for a root for my "new" Samsung J3 Prime (SM-J327W) that I got from my sister. I did the OEM Unlock and in ODIN Mode, it says that it's also "FRP LOCK : OFF". So far, CF-Auto-Root didn't work and all TWRP images, that I found, wouldn't even download on the device . I tried images for the "T", "P" and "U" variants also. The "P" one, lead to bootloop (I recovered stock rom since I got it). So is there any root for this device? It's on the latest versions of firmware and Android available for it.
Did you find anything for the J327W yet? I can only find ROMs for the 320, 327P and 330. I've been having very erratic battery life for over a year. It started after a factory android update. Sometimes my battery life will drop from 70% down to less than 5% in a minute. I've done a factory reset, cleared the cache and replaced the battery but nothing has helped. Trying to put a new ROM OS on this POS is my last hope.

I think you'll need a battery replacement at this point... I did build a TWRP ROM myself for my popeltecan (code name of J327W in Canada apparently) but, according to a TWRP Builder Developer, my device might have some kernel issues with TWRP so I can share my ROM but I am not sure it will work on your device. Do you have your stock ROM in case?
Here is a GDrive link to my recoveries, there's the stock and the twrp one but be aware that you need all the ROM if there is a problem with the twrp (that means stock : BL, AP, CP and CSC). But you can use the stock recovery to build a device tree.

Replaced the battery about 3 months ago but it made no difference. I have some vacation time coming up so will have a little more free time to look into things.

Maybe a factory reset would be a good idea to try. If you want to try my twrp recovery build, you'll be wiping your data anyway. I highly suggest you to get the full stock rom since even just getting back the stock recovery could end up with a weird sort of corruption (like duplicated or unknown options inside the Settings app, or at least I experienced that). I am not responsible if it breaks anything, you were warned to get your precautions such as getting the stock rom.

hi if your still looking. i looked into it and the j327u twrp does work on j327w. i had the same problem trying to gain SU access with the other image files for j327w i had to use magisk zip and install it from twrp menu. had to format data and mount system in twrp.
twrp j327u does work but i could not get supersu or magisk to work, my build is J327WVLS4BSK1 with 8.1.0 oreo. i'm not sure there's a way to get past dm-verity using the boot patch by asphyx in the TWRP threads or the universal dm-verity workaround by zackptg5.
i first flashed twrp j327u using odin, ran up against dm-verity when running supersu. both MikasuX14 and another twrp j327w version i found would also flash and load, but the touchscreen wouldn't register my input. cfar didn't work either
sfirmware (website) has workable firmware for rev 4 j327w builds in case you need to recover your phone from soft brick - i could get my build's firmware to flash using the patched odin 13.3.3 version found on this site

heres what i did. i soft bricked, bootlooped and had to flash firmware from sfirmware a few times to get it to work
i used a twrp for j327u i found on a another similar thread on this topic. i flashed it with odin.
once inside twrp menu i went to wipe menu, i hit format, then back to mount menu, checked boxes data/system (previously data or system wouldnt check off before formatting data).once data and system were mounted i then
plugged phone back into computer while in twrp menu. the phone showed up as J327u cut/paste the latest magisk .exe into the internal storage of j327u (on computer) . i then on twrp menu found and installed magisk exe finally got it to properly install magisk i then in reboot menu hit system and reboot.
the phone restarted after awhile like it was factory reset but once i set up the phone magisk apk was already installed and root access was available. hope this helps.
so i've been busy for a long while before looking back into this. I will try again with the J327U rom. Right now, i struggle to find stock roms of the J327W because i flashed a not working twrp apparently and it locks my boot.
The J327U TWRP didn't work for me. Though, twrp itself works but i cannot get the system to boot and i cannot get to root it, no matter what i tried, i ended up in boot loop.
I managed to root this phone without TWRP. I used Linux tools to do this so I'm not sure if it could work on Windows.
Requirements:
Stock ROM for your phone (I used samfirm.js to pull it from the Samsung servers but downloading from sammobile.com works too)
A way to extract zip files
A way to extract tar files
Heimdall flasher (https://www.glassechidna.com.au/heimdall/)
Magisk Manager APK
An Internet connection on your phone
A compatible USB connector for your phone
Of course, a SM-J327W running the stock Android firmware
Obligatory warning: This WILL void the warranty of your phone and permanently trigger the warranty void flag. It also WILL cause a factory reset, so back up all your data first.
Bear with me, because there are a lot of steps. This will take around 15 to 30 minutes.
You will need to download and extract a stock ROM for your phone. Make sure that you download a ROM for the SM-J327W and not another model. Also make sure to download the latest version available.
Stock ROMs usually come in a zip file containing a few tar.md5 files. You will only need to extract the one that starts with "AP" for this procedure.
Step 1: Extract the tar.md5 file that starts with "AP" from your stock rom.
Step 2: Open the tar.md5 file in an archive manager. You may need to remove ".md5" from the end of the file.
Step 3: Extract the boot image (boot.img) from the AP file.
Step 4: Upload the boot image and the Magisk Manager APK to your phone. You can use ADB to transfer the files. For example:
adb push boot.img /storage/emulated/0
adb push Magisk-v22.0.apk /storage/emulated/0
Step 5: Open the files app on your phone. Navigate to the internal storage and tap on the Magisk APK file to install it. You may be prompted to allow installation from unknown sources.
Step 6: Open the Magisk app. It should say that Magisk isn't installed and it shoulld say "Yes" beside "Ramdisk". Tap the cogwheel icon in the top-right corner.
Step 7: Due to a bug in Magisk, you need to install version 21 instead of the latest version (v22). Set the update channel to "Custom Channel".
Step 8: When prompted, enter the following URL: "https://raw.githubusercontent.com/t...d863d3a15c6a2276b1061a280ece80ed7/stable.json" (Without the quotes.)
Step 9: Now it's time to patch the boot.img file. Tap the button to install Magisk and select the option to patch a file. When prompted, navigate to the internal storage and select the boot.img file that you transferred previously.
Step 10: Magisk will patch the file and tell you where it saved the patched file. Transfer the patched file to your computer. You can use ADB for this, for example:
adb pull /storage/emulated/0/Download/magisk_patched_XXXXX.img
Remember to replace the Xs with the the random characters that Magisk added to the file name.
Step 11: Reboot your phone into Download mode. You can shut it down and then hold the power, home, and volume down buttons at the same time to enter Download mode or use ADB: "adb reboot bootloader"
Step 12: A warning may show about the dangers of installing a custom OS. Press the volume up key to continue.
Step 13: The screen should now show "Downloading... Do not turn off target." If your phone isn't already plugged into your computer, plug it in now.
Step 14: Use Heimdall flasher to flash the patched boot image. For example:
heimdall flash --BOOT magisk_patched_XXXXX.img
Again, replace the Xs with the random characters that Magisk added to the file name.
Step 15: After a few seconds, Heimdall should report that the flash succeeded and your phone will reboot. It may take longer than usual. Leave it to do its thing and DO NOT pull out the battery.
Step 16: Your phone will show a notice that unauthorized changes have been detected and will prompt you to factory reset it. Press the button to perform the factory reset.
Step 17: Set up your phone as if it was new. It's not rooted yet, but you're really close if you got so far.
Step 18: Once you reach the home screen, upload the Magisk Manager APK to your phone again and install it like before.
Step 19: Open Magisk Manager. It will show that Magisk is installed and may prompt you to reboot to complete installation. Do not update Magisk to v22 or you will lose root access and you will have to flash the patched image again.
In the (very unlikely) case that your phone doesn't boot after flashing the patched boot.img, you can simply flash the original boot image and it should be fixed.
CONGRATULATIONS! You just rooted your SM-J327W successfully.
I also managed to port TWRP to this phone with the touchscreen working using the kernel from a recovery image for the SM-J327P found here: https://forum.xda-developers.com/t/...-1-samsung-galaxy-j3-emerge-sm-j327p.3573607/. All the partitions are mapped correctly. Due to a bug (presumably with the kernel), the data partition can unfortunately only be mounted read-only. However, this shouldn't affect being able to flash zips on your phone and you can insert an SD card to write backups onto. In the future, I may port CWM recovery to this phone using the stock kernel to be able to mount the data partition read-write.
You can find my custom recovery attached to this reply.
Follow up: It seems that the bug that causes Magisk to fail is fixed in the latest version (v22.1.) As a result, steps 6-8 in my previous post are unnecessary.

Stuck in CrashDump Mode

I just purchased a new OnePlus 7 Pro yesterday and immediately set about rooting it. This is the process I followed:
fastboot oem unlock
fastboot flash boot twrp-3.3.1-4-guacamole.img
TWRP: Install > Select Storage > Internal Storage > Magisk-v20.3.zip
TWRP: Wipe > Format Data
I rebooted and was confused when I wasn't rooted. It seemed the last step had undone my root, so I went back into TWRP and installed Magisk again this time without formatting data. When I rebooted I had root and all was well.
However, there was an OEM update available that warned me it would remove root if I installed it. I found this guide to install an OEM update without losing root, which basically says to download the update via Oxygen Updater and then install it from TWRP. On step 6 is says to select the "Inject TWRP after install" option, but this didn't exist in my TWRP. I went ahead without it, thinking maybe it was enabled by default in my newer version of TWRP. The installation seemed to go without a hitch, but when I rebooted after I was stuck in fastboot. I couldn't boot my phone, nor could I get back into TWRP or regular recovery, only fastboot.
I tried flashing TWRP again using fastboot, but to no avail. I also tried running fastboot -w, but was still stuck in fastboot. I did some more research and found this comment which made it seem like all I had to do was download 10.0-GM21AA-OnePlus7ProOxygen_21.O.20_OTA_020_all_1909172051_db7a3f61-FASTBOOT from here and then run flash-all.bat. Once I did so I ended up stuck on the following screen:
Code:
QUALCOMM CrashDump Mode
--------------------------
dm-verify device corrupted Force Dump
kernel_restart
I can't seem to do anything at all with my device; not even turn it off. I tried holding the power button down for nearly a minute and no response from the phone. Is there any hope at all for my phone or have I properly destroyed it?
https://forum.xda-developers.com/oneplus-7-pro/help/mistake-kernel-error-t4029743
Same thing happened to me and I searched around a bit and found resolution. You can try what I did or try msm tool but search first as crashdump error is becoming common issue it seems
I held both volume buttons until restart and let go of one of them to get into recovery and then boot to boot loader if needed
Thank you so much! I thought I'd corrupted fastboot and permanently bricked the phone.
Once I was in fastboot I used tool all in one to flash 9.5.13-GM21AA-OnePlus7ProOxygen_21.O.16_OTA_016_all_1908281716_b2bb5-FASTBOOT.zip onto my phone by picking Flash Factory Images, and now it's back up and running.

This was the magic trick I needed to know. Holding both volume buttons didn't quite work for me. I held them both down for over a minute and nothing happened. Then I tried holding down the power button and that seemed to work after several seconds. I didn't hold down volume down quickly enough the first time, so I had to do it again. I held both volume buttons and the power button for over a minute, but again, nothing. I tried a couple more times and got it to work. Haven't been able to figure out exactly what causes it to exit the CrashDump mode, but the volume buttons together seems to be the important part.
This time I tried doing the OEM updates first, thinking that attempting to install them manually is what caused my problem. First I installed the 10.0.3.GM21AA update, then after rebooting I installed the 10.3.0.GM21AA update. At this point it said my system was up to date, so I want ahead and booted into fastboot and ran fastboot flash boot twrp-3.3.1-4-guacamole.img. No errors, but no TWRP either. My phone was stuck in fastboot again.
Is it necessary to stick with 9.5.13 if I want root? Is there some way to get TWRP to work with 10?

Just use tool to flash 9 then after first boot fasboot flash whatever 10 build you can find. Then after first boot of 10 try boot twrp and install twrp.
Honestly I just used the tool to root and flash recovery. There is a button for that and just pick your files. Good luck

You need to use a more recent versions of TWRP with Android 10. Current unofficial version -74 should work. So in your current condition, you should be able to simply boot TWRP (using the correct version), flash TWRP installer zip (if you want TWRP installed), flash Magisk (current version is 20.3) and reboot and you should have root again.
Easiest way I've found to install the OTA updates, is to simply install the update through the phone settings, do NOT reboot immediately after the update, go into Magisk Manager, flash TWRP installer zip as if it were a Magisk module (optional, if you want TWRP installed), then install Magisk picking the option "Install to inactive slot (after OTA)". Than just reboot, and you should be updated and with root.

Ah, I was using the Official TWRP App to get the images so I was under the impression that twrp-3.3.1-4-guacamole.img was the latest. I assume you're saying I should use TWRP 3.3.1-74 Unified Unofficial Q by mauronofrio from over here instead.

This is good to know. Thanks.
Just to follow up, I applied the available OTAs through the phone settings (up to bulid 10.3.0.GM21AA) and then followed the More articulated but fully functional instructions to install TWRP 3.3.1-74 Unified Unofficial Q. Everything went well and I'm now up to date and rooted. Thanks again to both of you!

That is the correct TWRP to use ("Unofficial" version -74), as it appears you have already determined.
I don't know why the "official" versions have fallen so far behind. It's been months stuck on version -4, so it seems that they have stopped going "official" for some reason. No matter, the unofficial versions are working fine (and in fact required for Android 10 as you now know), so the "official" tag seems like a technicality.
On these OnePlus phones I don't know why they love Qualcomm Crashdump mode. I fixed it sort of like you, but this worked 100%. You hold all 3 buttons (power, vol up, vol down) and you bypass the crashdump (takes several seconds 5 maybe 10), just quickly let go so you'll be in fastboot mode and can work your magic to fix the damn thing....
I even contacted OnePlus on an 8 they had no idea what to do...
Fastboot flash boot recovery.img <-- bad idea
Fastboot boot recovery.img <-- provit

Installing TWRP to Samsung Galaxy A8 (2018)

I have the phone mentioned in the subject. I followed this guide to install it. I don't have root yet, so obviously I followed the Odin Install method. The guide warns that after the first boot, the system will replace the new boot loader with the stock one, and this is exactly what happens. The guide says that I have to enter recovery mode and TWRP will fix this for me. However, I cannot enter recovery mode, because after finishing the download, the phone force-reboots, and I cannot even turn it off. The only thing I can do it is either let it boot and delete TWRP, or enter download mode again. How to solve this catch-22?
Actually, the first time I tried is to use Odin to install a patched system with Magisk, then install TWRP on the rooted phone. That works, but then I cannot update the system, because that requires Magisk to be installed from TWRP.

How to root *without* magisk?

Is there still a way to root our phones without using Magisk? I've given up trying to pass safetynet, it never worked even with magisk, and having root is more important to me. Systemless root buys me nothing, but it creates a lot of problems. Every time I need to reboot I need to go into recovery by pressing the button combo. Just today I didn't press the button combination quickly enough, it rebooted without magisk and (despite having flashed the multidisabler, vbmeta, etc) it somehow hosed the recovery partition, such that trying to boot into recovery it would just crash, so I lost root (I have no idea how this happened, really). I had to go back into downloader mode to re-flash twrp, which now works but without Magisk, and I'm still trying to restore things as they were, but honestly, if I could just install SuperSU instead of Magisk it would be so much easier.
Is there any modern replacement for SuperSU, which is unmaintained for years, other than Magisk?
