My S7 won't boot up/start - Samsung Galaxy S7 Questions and Answers

Ok, here's the deal....
My S7 isn't my main phone, switched to a S10 some mths ago, been using it as a secondary phone to stream music to a bluetooth speaker, anyway i let it discharge naturally last time i used it & i noticed the blue led had stayed on, tried turning it on & it wouldn't come on, so proceeded to try & charge it - upon doing so the standard charging screen comes up, but it never gets to the % charge bit whereupon you can turn the phone on, also after a while it displays a download screen, saying don't turn off target, even if you try & boot the phone now it doesn't get very far, just the initial samsung loader screen! Anyone any ideas?

If you don't care about keeping data.
Charge phone, boot into recovery, factory reset.
If you want to keep data.
Charge phone, boot into download, flash firmware with Odin use Home_csc. Let phone reboot.

[Q] Screen won't stay on for more than an Instant

ok, weird issue.
Yesterday I came back to my TF having left it inmy bag for the day, and it would not turn on at all.
I tried various things and then decided that the battery must be totally dead.
I left it to charge over night, and come the morning was able to watch it booting.
However once It finished boot it goes to black screen. Pressing the power button sometimes gives a flicker of backlight and then goes blank again. sometimes it even gives a glimpse of the screen.
Plugging in the power sometimes gives a longer blink of the booted ROM.
I have tried a cold boot, a full data wipe and I have used NV flash to fully reinstall the ROM (Prime 1.8)
After the full reinstall I go through the Google initial setup process without a problem, as soon as the rom boots I am back to the flicker of screen going off..
Does anyone have any ideas??
Still got the problem, does this sound like hardware to anyone else?
if the screen doesnt work during boot it is hardware problem. flash ur rom again or wipe it

Screen works fine during boot
Done both of your suggestions unfortunately, as I stated in my original posting.
I am going to try going back to Stock, and assuming its an app NOT restore any during the rebuild process.

Dead photon?

Hello, my Photon started acting up really weird. First of all, it was really slow. I thought it's because I had like 150MB left and it was nearly full data-wise. However, I erased most of the data, and left it with 3GB left. Didn't work and it got worse.
I have these stripes around the display (just at sides, not at middle), while phone is turned on. Doesn't matter if in system, or at boot logo. Doesn't matter, because whenever I get to system, I can be in system for like 1 minute, then every application starts crashing (Apex launcher, Google play, whatever you pick) and I basically can't get anywhere. Also if I go to sleep mode, phone is basically dead and it's pure luck when I will turn on phone again. I am trying every few minutes and it's worthless, because any time I get to system anyway, I crash after few seconds.
What to do? I was planing to install custom ROM yesterday, but never got to that, because this all started to act up. So what should I do? Reset system? Any other ideas? Is phone dead?
Sorry for bad english, no bully please.
Thanks in advance
Update - now when I am trying to start up my phone, I have just black screen with white lines in the middle. Then phone shuts down. I will give more info when I will be at home and can get phone on charger
Well definitely try to charge the device up. You might try re-flashing the stock ROM using RSD Lite... Although from your description I fear your issue may be hardware related.
Could turn device on. Apparently that black screen with white lines was just discharged phone. When I put it on charger, I could again boot into system and it was working until I pressed power button to go to sleep mode and phone is again dead. Will try to flash RSD Lite later today and will post what happened

Charge the device as much as you possibly can before doing anything with RSD. Ideally you should have at least 50% battery in the device when flashing anything.
This is really miserable. I can't really get into bootloader. Because phone after that 'crash' or whatever you want to call it is dead and I can't even see if it's turned on or not. Basically I am randomly waiting when it's gonna restart and then I just get into system. Even if I fully discharge it, it will have black screen with white lines first, it flashes quite couple times and then it will finally boot into system. Also I remember it was ***** in past to get into recovery. Can I do anything from system? Because as soon as I don't turn off my screen by power button, phone is working, though it has those lines on side of LCD (I will try to borrow camera from someone and post it here today).
I set automatic turning screen off for 10 minutes and I am really careful about pressing power button. Sucks there is only option for just 10 minutes, so I have to tap on screen at least for once every 10 minutes or I will not have working phone. **** my life, really.

Why can't you turn the phone off and charge it while off, or boot to recovery and charge the phone in recovery?

About charging it while turned off - Can't because when I try to turn it on again, it's roulette when I get finally bootloader logo and not black screen with white stripes.
And boot to recovery. Is it possible to like download some command prompt application and boot to bootloader from there? I know when I had my G1 (and when I actually understood android ) you could boot to recovery or bootloader via console. I have astro installed on phone, so downloading some console application and installing it shouldn't be problem.
Btw as we are speaking, I tried to call someone and I basically get same thing like when I am going to sleep mode, I get black screen and now I am just waiting, when phone will eventually want to restart itself.

Still sounds like some sort of a hardware issue, is the phone new to you?
You can certainly force bootloader mode, in several ways. When it's off you can hold power + camera and it will give you a choice of what to boot. When it's in Android you can do "adb reboot recovery" or "adb reboot bootloader" depending on where you want to end up. There are various apps which can also do this for you, if you are on the stock ROM but rooted.

Phone is not new. I bought it used about one year ago.
I am not entirely new to android, but I didn't have android phone for 2 years and then I got this one. So I am really pretty **** with android atm
I will try reboot to bootloader from some console application.
I am rooted, opened bootloader, stock rom
Finally got into recovery, what now?
Also, when I once booted to system, I downloaded some root checking app, and root apparently isn't here. Well cornholio told me it is rooted back when I gave him my phone to perform sim card mod, but whatever. However, I am in recovery, but device is not detected by RSD Lite.

Well reading back thru this thread, I was suggesting RSD Lite back to stock. I'm not really sure what you want to achieve tho, what your "final" goal is here.
I'm not even sure what kind of recovery you are booted into - stock recovery? CWM?
Either way, if you want to RSD the phone back to stock, you need to boot into fastboot/bootloader mode - not recovery. Just make sure the phone is charged up as much as possible before flashing in RSD.
Oh, sorry - misunderstanding from my side, thought I can switch to fastboot from recovery, oh well.
Also yeah, stock recovery.
To spread more facts - in case somebody would have similiar problems, when I try to just turn phone on, I have zero success what so ever. There's just this blank black page flashing every few seconds. However, when I remove back cover, I somehow force phone to load to bootloader logo, then I finally get chance to force phone to get to recovery. I will try to get to fastboot

Not sure if stock recovery has adb enabled, but if you have adb you can 'adb reboot bootloader'.
Otherwise do the power+cam trick I mentioned earlier.

Did you remove the getvar lines from the xml file...?
Yes
Weird. I only recall seeing that when people were trying to downgrade... but you are flashing 4.1.2.
The phone is in fastboot mode? What happens when you click "show device"? The "Device Properties" section is eerily empty.
I know it sounds shady, when I am coming back here again in few weeks, just been a bit busy lately, sorry about that.
However, somehow I got phone to flash it. The white graphical lines on sides dissapeared, however I got some new bug - I can't use phone in portrait mode, just in landscape - aka I need to swipe keyboard to have phone working. Also, that thing when phone completely stops working now occurs only when I am in that portrait mode, but I can restart phone this time.
When I finished this, it was midnight so I went to bad, so I tried to set up alarm, if it's gonna randomly shutdown like before and unfortunately, yes it did. I was waken up with this classical white line graphical bug black screen and had to reboot the phone. Oh well, managed to boot to system and it takes 5 minutes to fetch sim card (I have sim card mod from cornholio) and as I said, those white lines on side aka mysterious graphical bug is back.
Unfortunately for me, starts looking like real hardware issue now

S6 keeps Rebooting

Hello all,
Today my Verizon S6 (on CleanRom 1.5) started to keep rebooting. After it boots, I can use the phone for less than a minute until it reboots again.
Here's how it began to happen today, if it helps.
- I didn't plug my phone to a charger last night, and when I woke up the phone had like 0%~1% battery. The phone died soon after I picked up the phone.
- At the same time I turned on the phone, I connected it to the stock charger.
- I used it for like 1-2 minutes, and the phone seemed to get confused whether it should die again or not (at 0% battery level)
- Then the phone decided to die again, and keeps rebooting itself.
My guess is something related to booting, initializing, or battery might have gone wrong. Also the soft button lights get never turn on.
Now I cannot use the phone really, as it dies like 30 seconds after I swipe the lockscreen.
- I tried to boot into safe mode, it didn't help.
- I wiped cache partition, it didn't help either.
The last thing I would like to try is to odin CleanRom again (or factory reset) but I would like to try other things first because I cannot even backup the data as it keeps rebooting. Odin will wipe all the data in my phone.
Any help or suggestions guys?

The OE2 tar file shouldn't wipe your phone as it is not a full wipe tar. I don't know if your phone would do it with it's reboot problem but a dirty flash of clean rom shouldn't wipe your phone either. However, a reboot during the middle of either of those would not be good. Flashfire does seem to be able to keep a phone from rebooting once it gets going or at least it has for me when I have been caught in a bad way before.
Problem Solved!!!
Thank you Tulsadiver for your suggestions. But is it okay to do odin without wiping anything?
I almost gave up after struggling several hours and thought about doing a factory reset, but the problem is solved now.
I found it weird that the soft key lights never turn on, so I thought that there might have been something wrong with the power management. So I turned the ultra power saving mode on (fortunately the phone didn't reboot before I did that), and it didn't reboot itself. I turned it back off then now the problem is gone!
I am happy with it now, and this might be one of the things to try if you experience a random reboot.

Samsung GT-P3110 Bricked(?)

Hello, recently I started reading comics and found my old tab lying around so ill give it a go
First thing first it wont boot becaue it had no charge obviously (been there for like some years), then I tried to plug the charger but to no avail
I cleaned the contacts of the charger with a dry brush and start charging which then my tab starts charging!
when I booted, I think it was CM 12 (or 13? the one with andy I believe) and everything is force stopping.
I then tried to go to recovery mode and wipe data, but when i rebooted it it just stuck with the splash screen (the one before bootanimation)
I turned the tab off and tried to boot to download/recovery mode but it would just boot me right to the splash screen again, which mean i cant go to TWRP or ODIN.
And it doesn't always want to turn on, sometimes it just stuck there with black screen (not turned on) even if i press power/combo button, sometimes it pop up to the splash screen. what i notice is that i should wait for the charging indicator to show up before i can try to boot again (i got enough juice now, 56% the last time it turned on)
also one thing i remember is something about F2FS but im not sure what that is, but that might be a clue to my situation so ill just write this down here
Hi
Same here with P5110 and Slim7. I can't start it anymore....
I didn't use it for some time and then i charged it to 100% and it started but everything seemed to lag. Then i turned it off and wanted to look for another rom or a newer build. But i can't start it anymore. when i plug in the charger i can see the charging screen but beside of that i can do nothing. It has no effect when i push the on/off button or anything else...and it has to be at nearly 100%...

Phone dosen't turn on,help!

Hello there,i am new out here and my native language isn't english so i am saying sorry by now.
My A7 2018 rested on my desk,with 10% battery,and suddently the phone shuts down.It has happened to me before,but somehow i was able to turn it on and didnt have problems since.
Sometimes the phone's battery ran out fast when it was like 30%.
I plugged in the charging cable and it showed me a charging-logo-like thing but i cannot post any links here since i am new.
I thought i drained out the phone's battery and i let it rest and charge for like 30 minutes.
I did a force boot thing where u hold the down and power buttons for 20 seconds but nothing happened.
Sometimes the phone turned on but closed back on at the booting where it showed powered by android.
I plugged in the phone into my computer and into device manager at other devices it showed me exynos7885.Usb debugging is off if that helps.
I called samsung support and they have told me to bring it in for warranty at my phone carrier where i brought it from but i can't bring it in because it is scrached and the camera back glass is cracked so it dosent meets the requirements for my warranty.
I have all my photos,phone numbers,conversations and passwords on it so please help because i didn't back them up!!!(lesson learned)
Please help!!!!
Try reflash stock rom with odin. As you cant get into download mode. You may have to use fastboot to boot into download mode.
its so easy, go to odin mode and make sure that you've already downloaded the stock rom and use odin for flashing. If you dont know how to use just search it on youtube or here in xda for guide.
