Root attempt Galaxy S8+ Touch screen unresponsive at TWRP - Samsung Galaxy S8 Questions and Answers

Hi, I followed this guide to root my S8+ https://forum.xda-developers.com/galaxy-s8/how-to/guide-how-to-install-twrp-root-galaxy-t3752480
Let's just say that I used the TWRP for the S8 instead of the S8+ and now I'm stuck at "swipe to allow modification", is there a way to unbrick the phone and maybe flash it back to stock?
I saw some threads that say to wait for the battery to die (I'm at 80% so it seems I gotta wait a long time) but after that what do I do? Do I try again to start it in download mode again and maybe this time use the correct TWRP or is there another option?
Thanks.
Edit 1: Battery lost 1% in an hour, this is gonna take a while
Edit 2: The power button + volume down button method doesn't work because the phone keeps rebooting the TWRP interface
Solved: Somehow repeating the action power button + volume down + Bixby button made my phone boot into download mode and now I've flashed the correct version of TWRP and touchscreen is responsive.

If you were to explain this to a child?

Can you boot back into phone normally ( press power button + volume down button until phone restart then release.)
If you can check in developer section to make sure OEM is unlocked and USB debugging on
Restart into download and reflash correct twrp for s8+ ( U can still use the link in your op if you like )

I'm sorry but the phone keeps rebooting the TWRP Interface even though I used the power button + volume down button method. I'm afraid I gotta wait for the battery to die. It's at 51% now

So you can you reboot and get into download mode at all. If so try and flash right twrp.
Also this is the latest twrp for s8+

if stuck on bootloop go to recovery and wipe data..
you can use cwm to wipe system and data and root/flash a custom rom
or you can use odin to flash stock rom (see dokys thread at top of dev section for firmware)
my device isnt rooted so i believe i cannot do the cwm method?

no, u can go into recovery without rooting
Steps:
1. Power off ur mobile
2. press volume up + home + power buttons
when u r in recovery the touch screen is disabled so u should use
volume up/down button to scroll up/down
power button to go back
home button to select

[SOLVED] help...soft brick!

Hi,
Today I stuffed up my phone... I owned a Sony Acro S and Transformer Prime, which I flashed custom roms and recoveries on both with no issues.
I thought I'd be ok to try my G2...I was wrong.
I was able to root the device perfectly, then searching around I found an apk file for flashing twerp recovery. Which I did then I chose to reboot the phone, thats when I got stuck on the LG start up screen and the LED flashed blue and green. Then I realized the way I tried to put twerp on isnt suitable for my model.though saying that if I hold the power and down button I can get into twerp, but then I reboot and get stuck on the LG screen again.
I am on Stock Kitkat and my model number is D802T Australian version.
Please help... step by step help would be great.
I thought I knew what I was doing and no im confused.
I have searched and tried a few methods which I was unable to fix my issue.
Thanks
Duane.

LG G2 Boot security error after trying to flash SuperSu after going to LineageOS 14.1

I've been using Cyanogenmod 13.1 (rooted) and I decided to flash a ROM with Nougat. I flashed lineage-14.1-20170320-nightly-d802-signed and open_gapps-arm-7.1-mini-20170325 and everything worked fine except I didn't have SuperSU. I tried flashing SuperSU-v2.79-201612051815 and when I tried to boot into system I got this screen (with the LG logo below) http://i.imgur.com/O7vOtab.png I tried many methods like this https://forum.xda-developers.com/showthread.php?t=2582142 and this https://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404 to no avail. In Linux when I used the ls /dev/sd* command in the terminal the phone wouldn't show up and later in Windows I got the PC to recognize the phone as Marshall USB Composite Device 9006 http://i.imgur.com/a5WHV9P.png and in Disk Management the phone partition shows up un-initialised http://i.imgur.com/XaVKIu7.png . Help I don't know what to do now. Tell me if I should provide more information.
I had the exact same problem. Then i found a solution. Just dont flash the normal Supersu, you need to flash the Supersu BUMPED file. Just go in recovery, press 10 sec the power button to be sure the phone is off, then hold volume down and power button until the logo appears, then release and press again (fast) then choose yes, yes. Just flash the Bumped and if recovery asks to do root choose NO.
The Bumped which worked for me

Yeah Bad same Problem, turned off and it went on, then again bootloop. But if you press the power button long enough then its completely off. In cyanogen mod i had Problem that i couldnt get into recovery with power button+volume down.
So you should flash kdz, get oneclickroot for LG g2, then autorec lollipop to get recovery. Then flash Rom + gapps + The bumped file.
If you dont know how to flash kdz, you can ask here. I will help
Good luck

Yeah Ok. When I wanted to turn It off, I just pressed the power button until the screen went black and the logo came again but after 2-3 sec the screen went black again, then it was off (just hold power button for 10sec)
Try that when your phone keeps restarting

Get the lg mobile support tool, install it. Then open and connect your phone via download mode, it will find the phone and download the kdz for it. That should work.
If it doesn't install automatically, click on additional options then click on set upgrade error back, or something like that.
Before all that install the driver from
http://www.lg.com/de/support/service-mobil-telefon/lg-G2
Then you can start with lg mobile support tool

Please help!

Hello everyone, from the title you've probably figured that I might be a noob and you'd be correct.
I have absolutely no idea what I'm doing. I'm trying to root and add TWRP to my phone, I've searched for a user friendly guide and this: "https://rootthedroid.com/root-leeco-le-max-2-install-twrp-recovery/" is the most user friendly guide I can find.
Something is not installing correctly and I think there are gaps in this guide, I'm pretty good at reading and following directions. I'm able to get into bootloader and Once I think I've installed TWRP the power button + volume down button does nothing when the phone is on except for take a screen shot and eventually shut down. However, when the phone is powered down, I'm able to hold the volume down + power buttons and it will eventually take me back to the bootloader screen but not to TWRP as the guide states it should.
So after this I thought I did something wrong and went to factory reset the phone.... When I initiated factory reset, that brought up the TWRP menu, so it was in fact installed onto the phone. I then continue the instructions in the guide. At the end, the power down + power button function does not work except for powering down the phone and bringing me back to the bootloader screen. I then installed the TWRP app and it still says that the device is not rooted.
I'm hoping someone can point me in the direction of a good thorough guide or please explain to me step by step how to get this thing rooted. I have x829 version and will be using primarily in Ohio if that matters. I'd also like some guidance on what ROM to choose.
Thank you for your time!!!!

You need to go for the right combination brother.....
Volume down with power button will take you to bootloader.....
For TWRP, press Volume up and power button simultaneously......
And for rooting flash magisk and you're good to go.....

This guy's got the right answer.
Please be sure to continue holding power and volume up until the words "recovery" come up on the screen otherwise it will just do a normal boot to Android.
Another method is to enable developer options (about phone and tap build 7 times), then to enable ADB, then use a PC and usb to the phone and use adb reboot recovery.
Also, if it boots to EUI ROM recovery instead of TWRP? It could be EUI ROM overwriting TWRP after flashing via fastboot.
The solution to that issue is to reboot into bootloader, flash recovery TWRP and then to either hold power and volume up to reboot into recovery or to use "fastboot boot TWRP.img" and then do reboot into recovery from there.

Samsung S10 Plus - Everytime I restart my phone Magisk would get unrooted. Need help

I am super new to rooting I mainly use it for PokemonGo. I am following this video on YouTube.
Basically when I flashed via Odin, I then install Magisk. Then everything is working and rooted BUT when I restart my phone my Magisk is then magically unrooted (I dont know if this is the right term) it says 'Magisk is not installed' and underneath that is says 'Magisk Manager is up to date'
So why does it keep doing this? Everytime this happens I need to Flash again via Odin and do the whole procedure again. This only happens when I restart the phone. Why does it keep doing this and how do I fix this? I will pay someone who can fix this for me. Ive been trying to figure out for the past day and Im going insane. I have no knowledge about rooting etc like i said i just want to play Pokemongo location spoofing.
Appreciate everyones help.
If you are on the stock ROM, you need to restart into recovery to activate Magisk.
Hi what is a stock rom and do I have that? What is this recovery? Sorry I am new

How do I do that?
You can press Power + Bixby + Volume Up then after seeing the bootloader warning screen, release all buttons so it can boot to the system.
You can also enable advanced restart in developer options.
Stock ROM is the one that comes with the phone.

Hi yes I remember doing the 'Power + Bixby + Volume Up' after flashing. So that part is done unless I'm doing something wrong?
What is this advance restart in developer options? Where is that and what does it do? If I do this what do I do after? Will this fix the Magisk not installed when I restart my phone? Also when I turn off my phone and turn it back on it works and it keeps Magisk so its just restarting the phone that is causing the problem.
Appreciate your help
So this topic is the same as the other one I replied to hence the "double vision" comment.
I believe you need to Power + Bixby + Volume Up every time you restart.
Advanced restart will allow you to enable rebooting into recovery (magisk mode), so you don't need to press the button combo, unless you need the actual recovery.
What guide did you use to install magisk?

If I press that when I restart phone then isn't that risky? If I mess up then I need to format my phone again to get magisk again?
Whats this advance rebooting? Will this fix my problem?
I followed this video https://youtu.be/o3a8YnWT3yk
Just looking at that video I'm not sure if advanced restart is an option on the stock ROM, i use LineageOS (custom ROM).
The button combo shouldn't be risky, if you hold it for too long just select the option to restart and try again.

I'm really confused so which part of the video am I suppose to do?
Since you already have magisk, you need to press the button combo every time you restart, if you want magisk.
Pressing the button combo activates magisk., and holding the button combo activates the recovery.

OK so everything I restart my phone I need to hold down bixy, volume up and power? When do i stop holding down the combo? Also let's say I mess up will my magisk not work or can I restart my phone again and do the combo or do I have to re flash via Odin and format phone? Sorry I just want to make sure because I've re flashed and formated my phone about 90000 times ?
Thank you
