SM-G955FD can only access Download Mode - Samsung Galaxy S8+ Questions & Answers

Hello everyone,
I apologize that my first post is directly asking for help but I've spent days reading and trying to figure out my issue to no avail.
I have a SM-G955FD and a few days ago it just turned off (battery at 40% and charging) and wouldn't turn back again (stock firmware, never rooted).
Recovery Mode (Pwr + Volume Up + Bixby) doesn't do a thing (Black Screen)
Download Mode (Pwr + Volume Down + Bixby) opens the Download Menu, if I proceed (Volume Up) , the device shows up in Odin.
I tracked the same firmware I had to flash it and found it. I load up the BL,AP,CP & CSC and proceed with flashing the device through ODIN.
Everything completes and I get a "PASS" from ODIN. However, when my phone reboots I get a blank screen with no vibration or logo or anything, it seems as if rebooting is actually turning the phone off.
Do you have any suggestions on what I can do? The device is still under warranty but I'd rather try everything within my ability to try and fix it.
Thank you so much folks.

Edit #1: Took it to a Samsung Repair Center and they told me I've voided my warranty because I installed a custom firmware. I clearly show them the "Download Menu" and how it's clearly marked "Official" & the Warranty Void bit/hex is 0 (I only flashed the same exact firmware from Sammobile using Odin, nothing even related to rooting which they claimed I did). They tell me this doesn't matter and that it's now out of warranty and if a software flash doesn't work then they would have to charge me 380$ (American Dollars).
I have a gut feeling that it's a software related thing at this point but my realistic assumption is that since the power button isn't causing the phone to vibrate it's probably a hardware issue.
What do you guys think?
I really apologize for the long posts, but I'm really pissed since the phone is barely 6 months old and I bought it unlocked.

did you try soft reset ? this is how :
To soft reset a frozen Galaxy S8 or S8 Plus you need to hold the power button and the volume-down button for roughly 7 seconds. Let go of the buttons once you feel the device vibrate and see the Samsung Galaxy S8 logo on the screen. Your phone will then reboot, and hopefully, start working properly once again
One thing to note: On the forced reboot/soft reset, you will be given four (4) options. Use the volume keys to navigate, and the “Bixby” key to select. Option 1 will do a normal boot, as if you’re turning the device on.
i hope your phone work again... try another Samsung repair center and don't explain anything just told them that your phone worked fine and one morning this problem appears... and nothing else don't mention Odin flash or....
i think this its storage problem or a hardware fail...

Hi there! No solution other than changing the motherboard. Went to another repair center and they did that in less than 2 hours and around a day to complete the water test.
Good luck

ODIN to stock without power button working? Is it possible?

Sorry for the long title but it states my predicament. Basically my power button is done and I can't boot into recovery anymore. It just is a endless cycle of reboots(vibrates everyone 15 seconds or so). I even tried to enter download mode, which it does but than restarts the bootloop issue. Anyhow, I've never used ODIN so someone please fill me in. I want to ODIN back to stock because it's my last hope and basically I can't get into recovery anymore anyway. But do I need to use my power button to ODIN? Also what if I can't get into ODIN mode because it just wants to continue to reboot. Any help? I'm at a lost here.
Oops, wrong section. Mods can you please move to Q&A...sorrrry.

Moved to Q and A. I suggest pulling your battery for at least thirty minutes or maybe an hour. Then put the battery back in(do not power on) and plug the phone into your charger and allow it to charge overnight. From what you have said the power button does indeed work but you have done something to your phone causing a boot loop. In the morning search XDA for Odin procedures (there are a plethora of them on XDA) and attempt your Odin to stock. If the phone continues to boot loop I hope you have insurance... I did this to my LG Optimus once... And couldn't save it...

It does "work" but not correctly. Apparency its a known issue and called SDS. basically the way it acts is that when I press the button, the phone
Is acting as if I pressed it twice. So I press it to turn screen off, screen comes right back on. Long press power button for reboot menu, flashes, dissapears and than comes right back. This I believe is why I can't boot into recovery or download mode. Not that the phones bricked, but the phone is having trouble recognizing power button hits.
So my last try was to Odin back to stock just to see if that helps. But when I hold the buttons down to get into download mode or select it in reboot menu, it boots into it real quick(I see download mode appear on screen) but than immediately starts looping. So when I use Odin, will it automatically boot into download mode for me? What about mobile Odin?

I had the same problem With my s3... It was out of warranty so I sent it to mobile tech videos to have the power switch repaired. It's been great ever since. I realize that doesn't really Answer your question about Odin, just figured I'd chime in with what I had to do. I was afraid to attempt to Odin or flash anything before the repair bc in my mind the phone believed the power button was being pressed repeatedly and that would make it interrupt the flash.
Also if you're under warranty, Samsung will most likely fix it despite being rooted. Mobile Tech Videos sounds like a great option too if you're out of warranty, glad to see there's an alternative way to get it fixed.

I don't have the phone in question but for my Samsung Vibrant (Galaxy S, T-mo variant) if you press and hold the Volume Up button while plugging in the charger or say your computer's USB port the phone will boot into download mode. Not sure if it will work for the S3 though. Hopefully it does! :fingers-crossed:
Also, for my work around, I've mapped the Volume up button within ROMs to 'POWER WAKE' to replace the power button. It's not needed but its an easy way to reboot to recovery if its implemented in the Roms power menu. Occasionally the phone will crash or the battery may die. If I'm at home, that's an easy fix, just boot up download mode and flash a kernel/modem/recovery via odin and make sure auto reboot is selected. The phone should boot, granted there are no errors. The only problem I have is when it crashes or battery dies and I'm not at home I can't turn on the phone. If anyone knows a way around powering on or booting into recovery without the use of the power button or odin/download mode I will be eternally grateful. I'm try to get my Vibrant in working order for my father whose never had a Smart phone. I myself have upgraded to the s4 and am glad I stuck with what I knew instead of getting the HTC One. =]

Read this thread. Power button issues on S2 might help and save you time and money. Or if you want to get into download mode use adb.. "adb reboot download " or can be done in terminal.

Ok so volume down + home button is download mode to flash things via Odin.
Volume Up + home button will bring you to Recovery.
Download your stock firmware from here or here
And flash it with Odin in download mode to unbrick your device.

Root attempt Galaxy S8+, touch screen unresponsive at TWRP

I'm going to try to keep this as simple as possible as I don't really know what I did wrong or how I ended up where I am now.
I have a Samsung Galaxy 8+ and I decided to root it. I decided to follow this guy's instructions on how to do it: youtube.com/watch?v=eh-I4uxAmUY.
I follow his steps and am bought to the "Unmodified System Partition" menu after having gone through the process of factory resetting, wiping my data and using Odin to flash twrp-3.1.0-r1_dreamlteks.
The problem is that now the touch screen is unresponsive. It does literally nothing.
I am stuck at the screen that says "Keep System Read only?" where I have to "Swipe to Unlock Modifications", but find myself unable to do so because my touch screen doesn't let me swipe!
So now I'm panicking:
Firstly, I can't get the phone to shut down. Holding the power button does nothing, even if I hold it for a full minute.
Secondly, I can't boot the phone into anything except this unresponsive TWRP thing.
Thirdly, my computer no longer recognizes my phone when I try to connect it via USB (might be unrelated?).
How ****ed am I?
Is my phone just bricked now?
Can I save this rooting attempt in any way, or at least revert to the stock?
Will bringing the phone to a retailer help me in any way, or have I already broken the warranty?
Please guys I am desperate for some assistance here.

You have voided your warranty so you can't take it down to the shop and get it replaced.
It isn't fully bricked because you can still boot into an "os" that isn't fully functional. It ain't recognised because you have to swipe past this and hop into the ADB sideload interface. Btw, try holding your home button, power button and volume up (or down) and report results.
If I was you, I would wait till the battery drains and shuts off and then let it be off for the rest of the night or something and then try again.

Alright, I'll give it until it passes out from battery loss and then get back on when things change. Thanks for the reply!

Please help! S10e can't enter download mode...

Please help!
Hello! This is a distress call, because I think I brickered my S10e, through my own fault ...
Trying to install the TWRP according to the instructions given in the Hades Rom, I made two unforgivable mistakes, since years of flashing roms ...
1) I took the wrong installation file (I have the G970F/DS, and flash the beyond2lte file, instead of beyond0lte)
2) I omitted to force boot of TWRP just flashed.
Result: I cannot enter download mode as I did before (the phone does not blink), and trying to enter recovery, out of 20 attempts, it only turned on 2 times and does not go beyond the warning screen that the oem is unlocked, and it is not a safe state. I press power to continue as it says, and the screen turns off. Of course it doesn't start normally with the power button either.
I found out recently that been connected to the PC, it is recognized by it, and I even could access to it though the Windows explorer... Ergo, it's not dead, but the screen is in the infamous "black screen of death". Tried the usb jig emulator, by sugestion of denon480, but it didn't work (see screen capture).
Is there a way to force it into download mode, to flash the correct recovery, or eventually an official firmware? The cell phone is immaculate, I can not resign myself to it turns paperweight !!!!!
I put this here, because the problem was in TWRP recovery flashing, I didn't arrived to the Hades ROM installing process, and this way I can reach more people...
I appreciate any help.
Cheers

I don't even think it is possible to brick Samsungs like that. Are you following the right steps to download mode? Ergo,
Step 1 – Turn OFF your Galaxy S10.
Step 2 – Now press and hold the following buttons on your phone together: Volume Down + Bixby Button.
Step 3 – Next, plug in one end of the USB-C cable to a computer and the other end to the phone. As soon as you will connect, your phone will power on.
I have the same problem. I do not know if the OEM unlocking has something to do with that as I can not turn on OEM although it is not missing but it is not active and can not be turned on. I tried all the solution available online but it looks like no one knows what to do even the so called experts know nothing at all and the only things they know is the direct easy way. So disappointed
Same problem here... any solutions?

Samsung A51 displaying logo but the touch screen makes sound

Hi everyone. So i have a weird problem with my friend's A51 galaxy. He told me to try and fix it, because he tought the phone was in boot loop. The phone is displaying logo samsung a51 knox etc. But when i tried to hold volume down+ power button it wont let me into recovery, it just restarts the phone and logo appears again. Holding volume up + power button doesnt help either. However i managed to jump into odin download mode by pressing volume up and down at the same time and connect cable. Now i have downloaded the correct firmware and managed to flash it, it was success, or so i thought. The phone restarted logo showed up and then small android logo saying "erasing" then it shows galaxy a51 knox, and its stuck again. I have noticed that the phone works, because the samsung talkback is saying to tap options to setup a phone and touchscreen works, but im just blindly going trough menus, and the voice is listing options but i cant setup phone like that. So can you guys please help me, is the issue display, or hardware, i have never encountered problem like this. Thank you all in advance and sorry for the long post.
You need to ask your friend for his google account email and password. You can't factory erase a Knox-locked phone without these.

But i managed to flash it with odin. If the phone display is stuck on logo but the touchscreen works and i have enter the phone setup, does it mean its hardware faulty? What could be the issue?

If it is knox-locked the phone will factory reset or flash as normal, but you'll still need the google acct that was associated with it if you want to reconfugure it, otherwise you're up the creek without a paddle.
