[SOLVED] Have i bricked my phone, or is there a way to fix it? - Samsung Galaxy S9+ Questions & Answers

I had recently installed evolution x, everything worked fine, but i stupidly hit the update button today and now im stuck on the twrp splash screen...
When it turns on i get the galaxy s9 plus splash screen then the twrp 3.5.2_9-0 splash screen.
I am not able to turn the phone off with the power button, i have to hold both volume down and power to restart it.
I have also left the phone overnight just incase it needed a bit of time but no luck, still just stuck on the twrp splash screen.
I have tried many hardware button combinations with no luck. I am unable to see the device on adb or fastboot, and i am unable to see the device when plugged in to install drivers for odin.
How do i fix this? (To be clear i dont care about the data on the phone, it is backed up but the phone is currently a paperweight in this state)
Edit [SOLVED]:
After weeks of googling i was able to find one thread for a different phone with a slightly different problem that said letting the phone run out of battery let them boot into download mode and it worked, as soon as i plugged in the phone and held the button combination i was able to get into download mode and install a later twrp version.
Hopefully other people can find this solution faster than i did

I am still looking for information on this if anyone has any.
I have also had to let the phone run out of battery and am hoping that doesnt make things worse.

Phone keeps booting in safe mode

Hi all my phone has some how only boots in Safe Mode for some reason. I'm running CM7 and whenever I boot my phone it doesn't go past the LG logo unless I press a button. However, whenever I press a button it takes me straight to safe mode. I've used Xiaona custom recovery to fix the boot load but that doesn't work either. I'm quite confused and discouraged because I've tried everything I can think of to fix this. None of my buttons are stuck IMO. I've search endlessly for solutions but have forum none, for most people, rebooting their phone takes them out of safe mode, that unfortunately isn't the case for me.
I've spent probably 8+ hours fooling around, I only got this phone yesterday so you can just imagine going from a beginner who knows nothing to having to use ADB commands and stuff to try and fix their phone. I'm finally ready to ask or beg for help. Please help me
Just wanted to say I've fixed this issue by holding down ALL 4 of the face keys on the phone while it was booting up. You have to hold them down until the phone is completely booted up. However, this is the only way I know how to fix it, unfortunately I have to do this everytime I boot my phone but I don't turn my phone off much so I'm happy as long as it's working.

[Q] LG Access LTE (L31L) Stuck on boot screen and wont go into recovery mode

Hey guys im new to this thread and a website said to see if you guys could help me. Well basically I tried to make my music louder on my android and it didnt like that. Now it wont boot or go into recovery and to make things worse, i made it go into charge only mode a long time ago. Since i cant open it or view files since its on charge only mode. I think im screwed. Is there any way i can fix this? Thanks a lot for anything. I tried to hard reset and all of that but it goes into a black screen then just goes back to the LG loading screen. It basically just loops itself everytime i try to enter recovery. It gets stuck on the tracfone page. This is a straight talk phone. Its the LG Access LTE L31L. Ive looked everywhere and havent found anything that works and thought that you guys would hopefully help me. Is it just a paperweight or is it fixable? Thanks!
In the computer the phone isent reconized as anything??
I found one in a car I just bought, has the lock for PIN enabled and cannot enter phone.
Tried all the reset options found on web, nothing brings me to recovery, searched the forums here for this model phone, nothing found.
Tried Volume Down + Power, released Power when LG logo appeared for 3 seconds then pressed and held, it would reboot sometime long sometimes short, but would not enter recovery, tried both volumes up and down, volume down and home button, every combination I could find...
I had a SIM card for a tracfone that was active and wanted to see if this phone would accept it...
Any other tricks available? Computer dings that it sees the phone, but since I cannot get past PIN screen I cannot choose what function USB should be and nothing is seen in Windows Explorer.
Any LG master files to force open the phone through the PC when locked like this or ???
Sorry to hijack or open an older thread, but not much action here for this model phone...

Jiayu G4 (God I hate to title it like this, but yes) stuck in bootloop

How the problem occurred
So a year or two ago I bought a Jiayu G4A/T/Whatever they're calling it and safely got it here. I've used the stock ROM for a bit but I wanted to get rid of the bloatware that was still on it, so I eventually ended up with a properly rooted phone with a ROM from Jiayu.es (Everything worked, have ClockworkMod as recovery, accessible via Mobileuncle Tools), which was essentially a stock Kitkat rom made to work for the phone. Now I got sick of the ROM and recently saw the new EMUI version on Huawei's P8 Lite, so I figured I'd look around for a tailored ROM running that, and ended up at "jiayu-emui-3-0-stable" from Needrom.
What I did
1. I downloaded a ROM from Needrom with identifier "jiayu-emui-3-0-stable" (I can't post external links)
2. Backed up my important files following a guide from androidcentral titled "[Guide] How to Backup and Restore Apps and Data when installing new ROMs" that I can't link,and did a full backup using CWM
3. Placed the ZIP on my internal SD card, went into recovery, wiped data/cache (not dalvik, since it wasn't described in the instructions, I think this might be a probable cause) and installed the new ROM from ZIP
4. Rebooted the phone and now it's stuck in the boot loop I mentioned.
What the problem is
Bootloops aren't that much of a problem usually, except this one is... I can't get into recovery mode. From there on it'd be cake, since I made the right preparations, but I can't get into it. While connected to my PC it keeps powering on, showing a splash screen from Jiayu.es briefly (which shouldn't be present anymore) and powering off after 10 seconds, only to come back to the splash screen.
What I've tried
I've unplugged it, removed the battery, waited to get a full power cycle and tried to hold my buttons in these combinations: [power button + volume up], [power button + volume down] - but neither work. It just keeps going with the boot loop. I can succesfully power it down, and when I plug it in from there it shows the low battery image. At the moment of seeing that I thought I could connect to it using ADB / Fastboot, but no luck there either. It keeps saying no devices found, and with fastboot it keeps on <waiting for device>.
My questions
What exactly can I do if there is no way for me to get into recovery mode? Are there any alternatives? How can I get my device to be recognized by ADB? Is that even possible? Why is this bootloop any different from others?
Update from the massive Q&A thread:
ZipAddict said:
Is it booting up on its own too after being off? This happened to wifes phone and it turned out the power button was stuck. I took a pencil and hit the power button with the eraser a few times and it worked then. Her case mustve dislogded it. I will keep my fingers crossed for u. If not send me a private message and i will look for an answer tomorrow and get back with u

Thank you for the reply!
Yes, it does. I took the battery out and let it lay disassembled for a night, after which I cleaned it a little and re-inserted the battery. With the case back on, nothing happened, so the power button wasn't stuck for sure. When I powered it back on with the power button (no USB attached) it showed the emblem for ~8 seconds and powered off. It then buzzes to show it's powered on again and up comes the splash screen again. Could it be that the ROM was just a rebooting falsehood? Why would it disallow me getting into recovery mode? I really hope there is something that can still force the device into recovery mode / interact with it somehow while in this state.
Oh, I also tried to see if the volume down button was broken but all the contacts seem intact, plus, they worked an hour before I started switching roms.

Bricked CAT S50 after general instability

Hello and thank you for anyone bothering to read this.
I got a CAT S50 and was experiencing a bit of instability lately.
I've run LTE_S0201121.0_S50_0.023.00 without a hitch for a while, then it decided to crash several applications, from google play to any other app open.
That's when I decided to do a factory reset and see if it would help. Performed the rest without a hitch, but the errors kept coming back. At one point, the screen went black. I knew the phone was on because the backlit was working. I hard-reseted it (hold the power button for 30 seconds or more) and rebooted. The phone froze on the CAT splash logo screen and that's when I hard-reset it again. But when I tried to turn it on, the phone simply refused to work. No vibrate, sounds or anything. It's dead.
When I plug it on the computer's USB, the PC makes a sound as if it detected the device, but when I go to the device manager, I get this QHSUSB_BULK with the yellow exclamation mark
I want to know if it is possible to unbrick this phone and if so, if there is a tutorial or if someone can direct me to the correct procedure. I looked everywhere for the ftf file for this phone to attempt this with flashtool, but I simply can't find it.
ANY help of any form is greatly appreciated.
Sadly I had the same thing happen to me, just a black screen. It decided to delete recovery mode or I just cant get to it.
Power Off the Phone,
While pressing Press Vol Down + Cam Button insert a Powersource -- hold down Vol Down + Cam
Recoverymenu should start
Then flash the original rom via ADB Sideload or SD Card.
btw. i have flashed the LTE_S0201121.0_S50_0.023.00 but i want test older ROMs!
can anyone link or upload an older ROM ?
Guy i have the same issue, can you please help me
I got the same problem I search lots place but still nothing then normal update rom anyone can help?

HTC One M9 screen stays black after trying to install Leedroid

Hello.
I hope someone here can help me.
I successfully flashed Leedroid on my HTC One M9 today. I still wanted to try another ROM, so I installed that one and then decided to go back to Leedroid. As I was flashing Leedroid again my phones screen suddenly turned black (I think at about 80%, didn't see it exactly though...) and after trying different things (combinations of buttons, charging and waiting some time) it won't turn on again. I can tell that the phone somehow boots up, because I can access all the files from my PC when I connect it via USB, also adb shows the device with "adb devices", but as offline. I selected a clean install of HTC_M9-port_LeeDrOiD_10_V4.0.0-R119_rev.78.zip from https://forum.xda-developers.com/one-m9/development/rom-leedroid-one-m9-v7-0-0-rc1-march-t3068468.
It seems like the phone only starts in some way if I press the power button and volume up and volume down, at least then I see the files on my computer.
UPDATE: I seem to be somewhere in the Setup (I guess), if I press Volume Up to turn up the sound and then press power and volume down I can hear the screenshot sound.
UPDATE 2: I figured out a way to get to the twrp recovery adb shell and tried restoring my backup (System, Data, Boot), but the screen stays black. I'm now hearing the default HTC boot sound, so my backup seems to be restored...
I can't post the install.log because I'm not allowed to post links and the text would be too long if I just posted it here...
Also I'm new to custom roms...
Does anyone know anything I can do right now? I have a full backup with twrp from before I installed any ROM, but I can't even see if the phones boots to some menu like the bootloader oder download mode, because the screen stays black...
Any help is greatly appreciated!
Update
If anyone finds this thread and is interested how it turned out:
Since I could not get the screen working again I sent my phone to a repair shop. They tested the phone and told me that a circuit board is broken and they can't repair it.
I'm still not sure how this whole thing happened, but it seems like I'm going to buy a new phone...
