Rooter S8+ after months suddenly stuck on teamwin (twrp) logo splashscreen - Samsung Galaxy S8+ Questions & Answers

Hi All,
I'm enjoying my first rooted phone for some months now. It's a s8+ with android 12.
But today out of nowhere my phone crashed and now i'm stuck on the teamwin logo page (3.5.2_9-0)
What i've tried:
Using odin again to install the exact same version from my downloads folder again. But this doesn't do a thing
Install a new twrp version from it's website. But then the samsung s8+ logo comes up, and the phone seems to restart immediately and ends in a loop.
I have no clue what to do and trying to search what i have to do but can't find anything but what i've done already.
This is my first rooted phone, so a bit of a noob.
edit: i've tried other versions, but it seems that only 3.5.2_9-0 gets through the samsung logo, but not further then the teamwin logo)n
And in can still enter download mode.
The logo seems to go away for a second every minute

At the moment i followed this tutorial (in januari)

My phone was 4 years old, i guess i'll buy a new one. Perhaps someone can tell me if i can reach my files. Most is backupped correctly but my signal (messenger) backup seems to be backuped to my phone itself instead of the SD card

SGH-I257M Soft Brick

I just recently got a S4 mini (SGH-I257M). I was trying to root it a few days ago (I think I accidentally used a file for the other models of the S4 mini) and after a reboot, my phone got stuck in a bootloop. I can boot into recovery but every time i select an option the screen flashes and goes back to the main recovery screen. I can boot perfectly into download mode though. I have tried flashing many stock ROMs but they all say FAIL on odin. Any help would be appreciated, thanks.

CyanogenMod Problems

A couple weeks ago I messed up my phone trying to flash a custom ROM. I'm just know fixing it and I just flashed my models ROM. (S4 US Cellular)
Here's my problem:
I installed CyanogenMod via SD Card, I flashed it, when I rebooted it flashed CyanogenMod and had the logo with arrows spinning around it, that moment of hope and pride lasted a mere 6 seconds as the screen turned off immediately. I tried booting it into recovery mode but all it does is show "Samsung Galaxy S4" and it turns off after a while. When I boot into Download Mode and hit "Restart" it does the same. I need help, thanks in advance!

Galaxy s6 G920v stuck in bootloop, have tried everything

Hi guys, so recently I bought a Galaxy S6 Verizon off of eBay. I got it for fairly cheap because it was stuck in a boot loop. I usually have no problem fixing stuff like this, but this time is different. So the first thing I tried when I got the phone was to do a reset and cache wipe from recovery. I rebooted the phone and it showed a screen that said "Android is starting, optimizing app 9 out of 31." when it got to 21 the phone rebooted and went back to 9. It did this several times before I attempted to wipe/reset again. I then downloaded the tar file G920VVRU4CPH1 and flashed it in Odin. I did a manual reset before the phone booted, and it is doing the same thing again. reboots to a green screen where it tries to optimize apps, stays there for about 20 seconds, and reboots over and over again in the same cycle. I have tried all other stock marshmallow roms that i can find, Odin won't flash older ones, (assuming its not letting me downgrade). Also another weird thing, every time I flash, the blue update screen goes to 32%, stops, erases, and reboots. Phone is on 6.0.1 version MMB29K.G920VVRU4CPH1 as seen in recovery. Any help would be gladly appreciated. Thank you!
I am having a similar problem with loading new rom. The farthest it gets is 32%. Sometimes it doesn't get even that far.
I ended up just buying a trashed s6 and swapping the motherboards. Only way I could fix it

Help, after flash TWRP and do factory reset instructions in Chinese

Ok I will admit it, I screwed up royally this time. My SM-N9150 (Hong Kong version) was slowing down and draining the battery fast. I could not get the downloader of a new stock ROM to work in Sammobile (tried multiple times, with adblock off but no go) and so I bit the bullet and used Kies to upgrade to Marshmallow. Of course this lost root but I figured I could just re-root (I had rooted using Odin with my old phone, but this one I had rooted using KingoRoot). However, none of the 1-click systems like KingoRoot worked, and neither did Chainfire via Odin (which caused problems on its own). So I flashed the latest CWM via ODIN. It said pass, so I went into recovery, did a backup, then did factory reset, installed SuperSu, wiped the caches and rebooted.
I kept getting weird errors where it would not let me boot into recovery or boot at all. so I thought that maybe CWM was not a good choice. I tried the newest version of TWRP but that gave me the "recovery is not seandroid enforcing" error. So I went back the CWM and tried wiping again.
After a very long Samsung logo bootloop, it eventually showed gearings turning but with instructions in Chinese. It then showed the logo again for long time and then showed something that had only 1 English word "system" and the rest in Chinese. There seemed to be 2 choices at the bottom of the dialog box. When I chose the one of the right, the phone showed a grey progress bar with Chinese letters above, but then went back into a bootloop; when I chose the one on the left, the phone turned off for a long time then restarted but again seems to be stuck at the Samsung logo screen before returning to the message with the word "system".
After it going into a bootloop that lasted over 1 hour, I pulled the battery and then went into recovery and tried restoring the backup I had made at the start. That just left me in the endless Samsung logo bootloop. I left it plugged in overnight hoping it would do something but nada. At one pint I did get a message "unfortunately, the system UI has stopped working" but screen was unresponsive to press OK, and it just went back into the bootloop.
I realize I did not do anything to unlock the bootloader. Would using KIES have locked the bootloader again? Could this be my problem, and if so, how do I fix it?

Bootloop Twrp

Hi, I've got an Honor 9 with unlocked bootloader and everything, today I was trying to change version of the Twrp because the one I had gave me some problems. So I decided for an older version ( "stf-twrp-zxz-0.2.img" found here), I flashed it and rebooted, but it freezed with the Teamwin logo and whatever combination of buttons I try to shut it down it keep booting in recovery, ending stuck in that situation. Thank you for your time.
P.S. If I connect the phone with a computer adb recognize the device and works fine, but I don't know how to handle it.
