Can't install TWRP on S8 Verizon G950-U Variant (Snapdragon) - Samsung Galaxy S8 Questions and Answers

My phone is rooted but I want to install TWRP so I can install Magisk to hide root status from some apps. I've tried downloading the TWRP official app but after I flash the latest img (3.2.1.0) and boot to recovery I get a "Start Up Failed" message.
I've also tried using Odin to flash it (without root status) and I keep getting "SHA 256" error. Any tips?

You can't flash TWRP if the bootloader is locked. Since it appears you have a US version of Verizon's S8, the bootloader is locked. I know they've released Safestrap which can be found here http://forum.xda-developers.com/galaxy-s8/development/recovery-locked-nougat-7-0-safestrap-t3772760, maybe that will help? I don't think you'll be able to flash Magisk though.....

Ah okay.. This is unfortunate hah. I only wanted TWRP to have Magisk in order to hide root status, but I guess I'd be better off unrooting then. Actually, I will try safestrap first. Thanks!
edit: Wait if I just downgrade firmware to anything 6.0+ that has TWRP working that should work right?

Doing a system-less root on s4 using magisk possible?

alright im thinking of doing system-less root with xposed using magisk (yes im a pokemon goer thats ticked off from its new update) just wanting to know what would be the best way to go about this. If it is possible. currently im running GoldenEYE rom android 5.0.1 dont have fastboot so i already know i have alot of work in Odin to do. would love to have CM12.1 running with a systemless root but last time i tried to even get CM12.1 loaded it never worked.
So anyidea if this is possible or not. (yes i do have stock roms at the ready from when i put on my current rom along with root methods)
You don't have to do anything in Odin.
All you need is TWRP.
Then follow the Magisk instructions.
Unroot, uninstall Xposed (if present), flash Magisk zip, flash phh root zip, download phh superuser app and Magisk manager app.
well that sucked. now have the dreaded unauthorized soft ware. found a way around it to get phone booted. going into download mode then cancel out restarting phone from there.
So I tried this exact thing two days ago because I have an S4 with the Goldeneye rom installed, and unfortunately got these results
I opened up superSU and did a full unroot, after
I deleted the xposed that was installed (v86 by dlc) using the uninstaller through TWRP.
Next I flashed magisk v6 zip along with the phh superuser zip, and ended up in a bootloop..
The phone wouldnt pass the boot animation, so i uninstalled magisk, and reflashed superSU
On my end its not working, mate.

As far as I know, systemless stuff works only on Android 6 and above.
Goldeneye is a TouchWiz ROM, therefor it's android 5.
Magisk works on Touchwiz 5.0
Magisk works on android 5.0 touchwiz. Im using lenny bard stock HPG1 rom and PoGo works perfectly
Sure you can do it. i have gt-i9500 variant with 5.1.1 port tw android. magisk work when i want to play pokemon go. the only problem i have now is the systemless xposed not working as expected.
I am under the impression I am not able to get TWRP on mine because its the later version with locked bootloader.. what options are there.. Currently Download Graded to 4.4.4 to use towel root and installed Flashfire so i can install Safestrap
Really want to use Magisk

I know this is pretty old but just a headsup if you have the latest bootloader that is locked you can just download firmware for your region with an older bootloader and flash the entire thing with odin. I had the locked bootloader issue and odin fixed it.

Hello
Im new here. I just want to ask you how can i root my lg spirit. Everything doesnt work and im newbie. Can you help me please ?
Are you on Marshmallow right now? If yes, you need to go to lolipop, root the phone, unlock the bootloader, flash stock Marshmallow through TWRP and flash a root package like SuperSU.

Now, you can install TWRP app from Playstore and download the latest twrp-3.1.1-0-c70n.img available for us. Then, download Flashify app and flash that .img downloaded.
Thus, you'll have a TWRP installed on your phone, from wich you'll able to flash wathever you want.
I did everything but after flashing v20b and supersu v2.78 i just lost root :/ why ?
but i rooted my phone by kingoroot cuz when i rooted it on kingroot than twrp always leave a message "fail flash"

If TWRP app is not working then try flashify.

[Q] Successful rooted, but /system is read only?

Hi guys, I have successfully rooted using temporary TWRP + modded magisk method, but now I gain root and checked via Root checker. But the problem is most of the root functions don't work as /system is read-only. Any idea?
Ya i have an idea.. Happened to me as well. I tried almoat everything but system won't be accessible anywhere.. I followed the same tutorial and installed magisk 13.4.
The only solution i could find was flash the latest factory image, and root again using supersu. I used the AIO tool by ghpranav and have got my phone rooted with xposed working without any issues.

I also fixed the issue. I flash the modified boot image and I am now gaining proper root access + Xposed. Get it working using Super SU, idk why Magisk keep failing thou. Was wanted to give Magisk a try, but it doesn't work properly on our device.
Cool:good:
Xposed isn't working with magisk? I was planning to install it

Guys, this is Magisk from Pixel. You can't expect that it is working. I wrote to MagiskDevs already, they are working on a own Version for Mi A1. Use for that time normal SuperSU (Xposed works normally )
how to??

You need flash back stock boot image first, due to some limitations you can't have TWRP and SuperSU root at the same time. If you don't have the stock boot image. I suggest download the ROM from MIUI and then flash it. You can choose "flash_all_except_storage" option, this will keep your data.
http://en.miui.com/download-333.html
After flashing. Reboot back to fastboot and then:
Code:
fastboot oem unlock
After that just run root.bat from the cf-auto root folder you downloaded and wait for it to automatically reboot your phone. You should have root now, if you wish you can download SuperSU from the store.

I actually tried before, and I tell you the results:
Option 1 TWRP installed + Rooted with Magisk
= Pretty much useless as /system is read-only. Every root app doesn't function, unless it is system-less. But system-less modules nearly all doesn't work as the Magisk version too old. And this method won't trip safetynet
Option 2 no TWRP + Rooted with SuperSU (cf-root method) -- Currently using this state
= Got proper root access, Xposed works but will trip safetynet
Option 3 TWRP installed + Rooted with SuperSU (cf-root method)
= Don't try this, will cause your phone stuck in boot loop

The best bet and possible trouble free is to first download the stock ROM from MIUI, reflash it and then root.

No, it will cause your phone stuck it boot loop if you try to flash the SuperSU zip directly from the official ChainFire site. I think probably is the AB partitioning problem or some sort (unsure). As I said you need to run CF-Auto root to get proper root access, otherwise flashing Magisk through TWRP will makes most of the root apps does not work properly unless it also uses system-less root function.

No if you want proper root with CF-auto root you must not have TWRP installed. You either choose TWRP + Magisk (non-working root) or no TWRP but with SuperSU (working root, Xposed works too).

BL unlock and Magisk, will OTA updates work?

Hi,
So I'm just step before unlocking Bootloader and flashing Magisk but the question is - will I be able to install OTA updates directly from android without triggering bootloop?

I'm not 100% sure but I think once you obtain root OTAs won't get applied because you would have flashed custom recovery while getting root access.

Alright so the full zip will be auto downloaded if there's something modified. Can it detect magisk and replace the boot image as well since it's not a system modification?
Is anyone having issues installing the OTA?
My device saw the update but when I hit install I get "Couldn't update installation problem" I have Magisk installed on the Tmobile oneplus 6T and I've tried to update after removing Magisk but it did not work, please advise.

Uninstall magisk and then try installing the OTA, if no go, flash the unmodified fastboot files and then try again.

As long as you don't hide system updates in Magisk hide system will prompt and download full zip instead of incremental and upon flash the full zip it will replace the boot to stock boot.

Uninstall Magisk and download and install full zip, you may require t-mobile certitied full zip if the global does not work so make sure you download from the system instead of the links floating around which will be the global rom.

Twrp is device specific not android version specific
Magisk generally works with all android versions
If you can unlock your bootloader your set to go
TWRP works on 955F on pie beta, but as I said there, it doesn't work on rooted or debloated devices.You can use TWRP, but without root.
I have pie. Twrp recovery, rooted magisk 18 and heavily debloated. Works fine.
Don't listen to him
how did they do it to root it? I have android foot beta 950F, thanks

This should help with the RMM state,twrp and root. As far as I am aware it's still the same process as with Oreo/nougat

Hi,
Does anyone know if it is currently possible to flash the update from twrp without a reset and maintain root? Or if root if possible how to achieve it?
I have the same question, any way to do it without wiping all data..? or rooting without TWRP impossible? like kingroot or something.
Pie update (official) messed my s8 and it got stuck on bootloop, i had to flash trough odin and now i have broken knox forever, great.. I don't want to wipe all data again and I would like to possibly unroot if i root.
