Question (fixed) Flashed Wrong TWRP - Samsung Galaxy S21 Ultra

I flashed the wrong TWRP now my screen is just black every now and again it will just reset itself and the screen will go black again. I have tried putting it into download mode but I can't seem to be able to do this and was wondering if there was a fix.

If you were able to fix this, please share how you did. You might be able to help someone else with the same problem.

[Q] Captivate screw up

Hi there. I looked all over the internet, and could not find a solution to my problem, or anyone else it has happened to. I am in canada on the rogers network with my captivate. It was running gingerbread, and I rooted it. It worked for about 10 minutes, and then would constantly reboot, as in boot up, 10 seconds later reboot. I tried fixing it by reflashing it, but now it just goes to the bricked screen. I can get it into download mode, but when I try to reflash with odin, it fails, although it does recognize it. Please help. Is it fixable ?
Okay, I think I managed to flash it to froyo, but now it just goes to a black screen after the S screen, and the bottom buttons are lit up, and it vibrates occasionaly.

This sounds like you are having the issue that I was having a while back, put it into recovery mode and use the Odin one click for the i896 (http://forum.xda-developers.com/showthread.php?t=979133) to flash it. Let me know if you're still having any problems.

Bricked LG G2 and I can't figure out a solution after looking

I've searched these forums for over an hour now and I can't seem to find a solution to my problem. I had the stock 24A software and I rooted it using ioroot and everything went fine. I then wanted to flash a custom recovery, so I used the steps found on Droid News. It gives a link to an app that you install and it's supposed to flash the recovery.
Once it tried to reboot, I ended up with a white screen that shows a dew lines of text (I attached a picture).
If I try to go into download mode, it will flash for a quick second and then go right back to the white screen. I can't seem to get into the recovery either. The website that gave the instructions for flashing TWRP talked about a similar error on Sprint phones and the cure was to flash the kernel again, but I'm not really sure how. The phone will respond to commands in fastboot, i.e fastboot reboot, but it just goes to the same screen again.
Please help, I'm a little stuck. Can I use fastboot to flash the kernel, if so, how?

[Q] Soft brick but no recovery

Hello everyone,
I tried looking for a solution to this problem, but either can't understand the suggestions or it doesn't really fit with my situation...
For some reason I managed to soft brick my TF701, trying to go back to stock after a CM install.
Anyways, I get stuck on the ASUS logo. I can access fastboot buf if I select RCK I get an error message. I can also connect in APX.
Any ideas on how I could flash a ROM on this device?
Many thanks in advance and sorry if there was an answer somewhere I missed...
I feel a bit ashamed now, I actually found a solution on my own and it wasn't that hard...
My main issue was not being able to access recovery. So I ended up doing the recommended steps here :
http://forum.xda-developers.com/showthread.php?t=2425581
up to the flash part and instead flashed this version of CWM
http://droidbasement.com/db-blog/?p=3568
This actually got me a working recovery, which I used to successfully flash a rom and my tablet is running again, as well as recovery mode.
Sorry for the thread, I could have managed on my own. If there's a way to delete it?

[SOLVED] Touch not working at all

Hi here!
I bought my Mi 8 some days ago (China version, since I live there), and yesterday I finally got time to work on it to move to Global or EU_multi.
After some minor trouble (bootloop after installing magisk), the touch screen now is not working anymore: wherever I touch it, no response, both in recovery (TWRP) and normal system boot. Everything else is working, I can flash ROM via fastboot, and the ROM (I tried official China and Global) are correctly booting, but then I should touch the screen to complete the first time boot and I'm blocked, because it is not responding to touches. All other buttons are working (I can turn off/on the screen with power button, and I can hear the related sound). I can boot to recovery and fastboot. Everything seems OK, except the touch itself.
Is it possible that I did something wrong while trying to flash magisk? or disabling dm-verity and forced encryption? or anything else that could have caused this issue?
I tried to flash different TWRP recovery and different official ROMs (China and Global), but no result, touch always not responding...
If anybody have suggestion, please say.
And thanks in advance!

How about going to the thread about 'non-functional touchscreen solution'. It will fix your exact problem. No need for a new thread, you should have searched first.

Rog phone 2 stuck on a bootloop without ever trying to install a custom rom

I have my rog 2 stuck in a bootloop. I don't really know why in the first place, because I don't like to change and mess around with custom roms. So i've never done that.
The case was that I was watching a video on YouTube and suddenly the touch screen stopped responding, the phone kept responding to other inputs such as the power button and the volume rocker. So I decided to restart the phone. And then it didn't turn on again. Got stuck in a boot loop.
I've been trying to fix it for a long time. But I just can't do it. Nor am I able to see what is happening with the phone. I have used this guide.
EVERYTHING works perfectly, it doesn't give me any errors during flashing or anything like that. Even the program tells me that the rom has been flashed correctly, and even the rog logo during boot, changes (I suppose because it is a version of the rom prior to the one I had.). The fact is that even with that the phone is still stuck in the bootloop. I have tried more things but this is the one that has taken me the furthest. I don't know what else to try. If anyone has any ideas, please tell me.
P.D. Sorry if my English is a bit rusty.
go back to stock and try other rom.

Any suggestions which rom I can use? I have tried the rom of the guide and the ones that Asus has on their website. None of them have bailed me out.
@Arnau17 Any Updates? I am facing the same issue. Mine reaches till boot logo and then freezes and reboots again. Tried flashing stock ROM as well but no Luck
I am in the same situation, tried several raw rom files, still in bootloop
USB plug correctly on side USB port? can you enter recovery or fastboot mode?
i have same problems before, if fixed after flash RAW rom, hope this help.
is there a guide to fix AVB VERIFY FAIL on Rog Phone 2
