Why did my phone get stuck in download mode? - Samsung Galaxy S7 Questions and Answers

I ran a TWRP backup today, and when I rebooted after finishing the backup, my phone got stuck in "Downloading, do not turn off target". I restarted a few times with vol down + home + power, and it went back to the same screen each time.
I figured something must have happened to the recovery, so I fired up Odin and reflashed TWRP onto the phone (without first checking that I really needed to do that). In TWRP, I restored the backup I just made, but to no avail. I had to go back to the previous backup a week ago before my phone would boot up and operate normally.
What was most likely the problem? I'd really like to avoid this happening again!

Apparently this is the problem:

The combination key you was pressing was the bootloader's combination, so obviously you'll reboot back to the download mode in a loop until you break the loop.
You probably, mistakenly rebooted to download mode from TWRP, of which you might not be remembering well.
There was no need to restore the old backup, all you had to do was reboot to system.
And yes, the right combination to get out of download mode is: VOLUME DOWN + POWER.

Ok thanks!

can't get into recovery mode

Hello guys, my TF300 has been rooted since it came out and i've only used AOKP rom and I have a fast boot app that I use to go into recovery mode or if need me I would just do the vol up and power.
Today I wanted to change my rom and I notice my fast boot wasn't going into recovery it just rebooted the tablet. so I tried the vol up and power and I just get a black screen, finally when I stop holding the buttons, it just reboots again.
I thought I lost root some how but so I opened some apps where I need root and they work and if I long press the power the built in recover that was there is no longer and when I turn it off and back on it still says "unlock" in the top left
the next thing I tried was I went into the playstore and download the goomanager and tried to download the TWRP 2 but it told me nothing is avail for my system.
As far as i know the only way To enter recovery is to restart or power on the tablet while holding down the vol down button then press the vol up when prompted. otherwise tablet will always fully restart.

[Q] Bootloader Loop. Help.

Okay so this is what happened. I had CM10.1 installed on my sgs3 (verizon). I followed this guys method to make my phone like i just picked it up from the store. Then i update to the latest version of android. After that i figured i would root it. The thing is that i somehow mest up while rooting it and my recovery mode didnt work so i used this method again
and now my phone is stuck on the inital boot sequence. Help me please. I didnt realize that your phone had to be rooted to use that method. the first time it worked fine. then the second time i forgot that that process unrooted my phone and did that method anyways.
Pull Battery.
Wait 30s
Leaving device Off,
Enter into Recovery mode by -
Holding 3 buttons at one time:
Power, Menu and Volume Up.
Do a Full Restore/Wipe
honk if you think captcha is dweeb paranoia!

What I did was the same as above followed by vol down.. otherwise it went back to bootloader odin mode (stuck). I also deleted odin for whatever effect that could have had. Then I flashed a new rom with twrp.
Power, Home & Vol up gets you into Recovery mode.
Power, Home & Vol down gets you into Bootloader.
Glad you got it working

HELP. Bootloop and I can't get into Recovery

Ok, so here's the thing. I flashed this theme, but it's not working and my phone won't boot. So I try to boot recovery, only I can't seem to get it. I hold down vol up + power till it reboots, then hold down vol down to get into recovery. Except it just keeps trying to boot, and doesn't load recovery. Anything I can do?
This is scaring me a lot. Need help. Thanks.
Ok, figured it out. The bootloop would go to a black screen when it froze. To get to recovery, I needed to switch to vol down 1 second before the HTC logo popped up. I used a timer to time myself properly and pulled it off.
In recovery, wiped data, restoring nandroid. Should be back up and running shortly.
I had a bootloop while on CleanRom 1.2 but since no one else reported it I just assumed that it was something I did. Probably was too.

Unusual bootloop - can't access recovery OR fastboot but loops on "optimzing apps"

Unusual bootloop - can't access recovery OR fastboot but loops on "optimzing apps"
I had my US version OpO 64GB working with CM12 for quite a while, rooted and bootloader unlocked with TWRP (possibly 2.8.6) installed, then some months ago I tried upgrading to CM12.1 through CM updater. This failed miserably - The phone started bootlooping on "Optimizing apps n of N" - as soon as it finished optimizing apps, the phone would reboot and start optimizing again. Booting to safe-mode (Power + VolUpDown) also fails in the same way (though optimizing fewer apps).
I tried rebooting to recovery mode holding Power + VolDown but it just gives a quick buzz (vibration motor) at the "1+" screen and reboots. The same thing happens when I try to boot to fastboot mode with Power + VolUp. So I'm completely stuck. All the guides show being able to boot either to fastboot or recovery (soft-brick) or else the screen being completely black/unresponsive (hard-brick). My phone is neither of these!
I got frustrated enough that I've let it sit on the shelf for the past 6 months, but now I'd like to fix this. All help appreciated.

Did you try clearing the cache and doing a factory reset ?

That's impossible for me to do since I can't get to launcher or recovery.
No acess to recovery?? Then better take it to service center... Atleast can u boot to fastboot mode or adb accesible then use oneplus one toolkits
---------- Post added at 11:34 AM ---------- Previous post was at 11:31 AM ----------
Install oneplus tool kit, while optimising apps it gets dectected by pc, just make it reboot mode & do reset.... Dnt worry this can be fixed, if all these seems messy then take it to service center

while things are loading, have u tried to hold vol up + power for 10 seconds or until the screen turns off and then hold vol down + power button until the oneplus logo?

Yes, just tried it. Same thing as described in my original post. When I hold power+volup the screen goes blank. I switch to power+voldown until the 1+ logo. At that point:
1. If I continue to hold the power+voldown key through the 1+ logo, the screen goes blank briefly, the phone vibrates once and reboots. If I continue to hold the power+voldown key, the vibrate&reboot cycle continues indefinitely
2. If I let go of either the power button, the voldown button, or both at or before the 1+ logo, the phone boots normally and goes to "Android is starting... Optimizing app n of 119). When the optimization finishes, the phone instantly reboots.
It's like the phone recovery is gone or inaccessible. Could this have to do with the phone tampering setting? As I said, I had this phone rooted and bootloader unlocked, working fine with CM12 for some time before trying an in-place upgrade to 12.1. That's when things went south.

Can't enter recovery mode anymore (TWRP)

Hi, I don't know what is happening, but I've been having issues with my phone. I was trying to enter recovery and pressed the button combination for fastboot instead. After that, I tried to get out of fastboot, but it kept going back to fastboot. I noticed holding up for a couple of seconds would boot me into my OS. When I try to enter recovery, the screen goes black and it restarts the phone. It will just keep going in a loop if I hold the buttons. My phone was rooted with magisk and I uninstalled to see if that would help, but it didn't.
I installed an update(I use lineage OS) out of curiosity to see if it would boot to recovery. It booted to fastboot, but after restarting and holding the recovery button combo it booted to twrp and installed the update, then restarted. Now my stupid mistake made my phone unusable. Everything is the same, except Lineage is stuck at the boot screen now. Sometimes it restarts to fastboot, but other times it stays there for possibly infinity.
I don't know what to do. All help is appreciated?
TL;DR Fixed, I think my volume down button was stuck.
Nevermind, I flashed with miflash and still had the problem, then for some reason it worked, but only once. I removed my phone from the case and found that it was booting to os. It is still kind of hard to enter the recovery. I think hitting volume up was cancelling the volume down which was stuck, or something. Now I'm pissed cause I wasted so much time on nothing
