Question Phone turns off after the SAMSUNG logo - Samsung Galaxy S21+

I was trying to flash my s21+ g996b with Odin and it failed at the beginning so I restarted the phone but it turned off after showing the Samsung logo the same thing happens if I try to go to recovery mode or safe mode thus I can't access them.
When I try plugging in the phone to my PC (or just charging with the adapter) it just keeps showing the logo like before and restarting shortly after and I can't stop it from looping.
Is there something I can do to stop the looping or go to recovery mode ?
I already have backed up my data, please let me now if there is anything I can do even if it means reset factory, etc.

So I got into download mode by pressing and holding vol up + vol down and then connecting the phone to the P.C. after. I did finally install the firmware, and all is good now.
Also, there are a bunch of different ways other people tried here, which I thought might help.
P.S. the original problem that led to broken firmware was a faulty cable.

[Q] Can anyone help me a bricked Samsung Galaxy Exhibit 2 4G?

Guys, I need help on my Samsung Galaxy Exhibit 2 4G. I had tried to do a factory reset but it looked like it got stuck after several minutes. I turned it off and after that, it i stuck on start-up. The Samsung logo would appear, eventually the green android mascot would appear (where it would look like it is rocketing up) the the samsung logo would appear again, then the green android mascot would appear again, and that would loop over and over again. This happens every time I turn on the phone.
Hooking the phone to the PC will try to install driver, (I have installed a lot of drivers) but it will fail and say unidentified device and the phone drive does not come up on the computer so I can not copy any file to the phone or card.
When I try to go into download mode (Power and Volume down combo) and attach Odin, it will recognize the phone but it gets stuck on Setup connection.
When I try to hold Power + Vol up and vol down combo, it will say ramdump mode cause: force upload
When I do manage to get into CWM with Power and Vol up combo, anything I choose (Romwipe, wipe data, etc) will just get stuck on the clockwork logo (hat and wheel like thing).
I would be very grateful if anyone could help me get my phone back to working.

Stuck In S/W Update Mode

Ok so I am trying to install ICS on my LG925 but I have a problem. My phone seems to be stuck in download mode. When I power off the phone the only way I am able to reboot it is to remove battery, plug usb into wall jack, plug usb into phone, hold volume up and power insert battery. When I see the lg logo I remove USB and the phone boots up. But like I said everytime I power down the phone I must go through this process. Already tried factory defaulting but it made no difference.
I am using lgmobile support tool to restore phone now. I believe I have already tried this without success though. The phone updates without a problem, but when rebooting the phone remains in s/w upgrade mode. (at least I believe that's what mode it's in the screen remains black but it does communicate with the pc.
After finally getting through the ICS install correctly my phone is now booting properly again. Nice to finally have ICS now to find and apply all the bug fixes.

[Completed] Galaxy s5 wont boot words show up flash read failure there is no pit binary- bootloop

Hey everyone,
Samsung Galaxy s5
Verizon
Fully stock as of October 10th 2015 (no sure the exact android operating system)
Not rooted or modified in any way
My wife's phone decided to kill itself yesterday. The phone worked fine in the morning then all of a sudden it stopped working. When you try to start the phone it will vibrate and nothing on screen shows up. After about 57 seconds (yes I timed it), the phone quickly displays:
ODIN: Flash read failure
ERROR: There is no pit binary
The phone then goes into a boot loop and repeats this process.
She did not approve any updates or anything, it just happened. I am assuming an app updated itself and the app was majorly corrupted and messed with the kernel?
I have tried the variety of reset options (hold power+Volume up+home screen) and it does nothing. Removing the battery and reinserting it does nothing as well. I tried to boot without the SD card and we get the same results. I can't get the phone into the menu to select recovery or anything.
When I plug the phone into my computer nothing happens. The computer does not recognize it and the phone does not respond. The phone does charge the battery, how do I know? I as well have a galaxy s5 but mine is on ATT. We swapped batteries and we could see that her phone was charging the battery.
I plugged my phone into my computer and it recognizes immediately. I can get into my phone and the SD card from the computer so that rules out the computer as a problem.
Is this hard or soft bricked?
Will a USB Jig force it to give me the download screen or recovery mode or is this thing dead?
Is there a way I can boot from the SD card even though I cant get into the recovery screen?

Sorry for the late response.
It's a strange issue. If you really have changed/flashed/updated nothing, you should first claim warranty (if still available) and send it for repair to the shop/Verzion/Samsung support.
If no warranty, then you may register on xda and ask in the Verizon Galaxy S 5 Q&A, Help & Troubleshooting forum ...
... but if you can boot neither into download mode (Hold Volume DOWN + HOME + POWER) nor into recovery mode (Hold Volume UP + HOME + POWER), it sounds like a hard-brick.
It could also be a screen issue ... but most likely nothing you can fix yourself ... without additional hardware and/or help.
So I recommend to search for a mobile repair/support shop.
Good luck !

Hard brick SM-G955F

Hi,
I tried flashing a ROM on my Galaxy S8+ using Odin yesterday and as I haven't flashed a Samsung before, I failed, which led to a bootloop.
By pressing and holding VOL - and POWER, I can turn the device off.
What doesn't work is putting the phone in either Download or Recovery mode.
It's not recognized by my computer through the USB-C cable and it doesn't always respond to being charged.
Sometimes when charging it, it boots up by its own and thus bootloops.
Is there any way to fix this? The Samsung Logo in the bootloop gives me hope.
Greetings
maybe if u datail what u did spet by step and how r u trying to go to download/recovery more can help.

Totally bricked S7, Exynos G930F, can't access Odin mode

Hey all,
a couple years back I messed up this S7 where I tried to get LineageOS running on it. Phone bricked, and has been stuck on Bootloop ever since.
Now I wanted to reflash a stock image, only problem is that I can't completely access download mode.
I reach the green screen with the warning message, but I can't press Volume Up or Volume Down to do anything else. Odin doesn't recognize it either.
So I am kinda stuck not being able to connect my phone to my computer at all for debugging purposes. I also tried to the VolUp + VolDown with USB cable with no success.
If anyone has clues where I could start my debugging, that would be great. Thanks.
I do have access to the battery to unplug it.
EDIT: I somehow managed to get into Odin Mode on my phone (I dont even know how, I held the button for more than a minute), but it's still not recognized on my Desktop.
EDIT 2: I tested the cable on my second S7, so it's not the connection. My PC won't pickup the damn thing no matter what I do
