BSOD - Can't get safe or recovery mode either - Samsung Galaxy S7 Questions and Answers

Hi folks. I've got a problem that I don't see anything quite matching in here. I have a Straight Talk/Verizon GS7. Last night I installed an app do to USB tethering on it. It worked great for the testing. After I disconnected and it sat idle for a while, I heard a notification sound and the blue light started flashing. I push the home key and the "back" and "window" key lit up, but the screen is black.
So here's what I've tried so far.
I tried to hold the power button to turn the phone off. Nothing.
I can soft reset by holding volume down and power. I get the splash screens for GS7, Samsung and TracFone. Then BSOD.
I can't get safe mode. I can't get recovery mode.
I can get to download mode. "Volume down, home, power"
The phone has developer tools turned on and USB debugging is enabled. Is there a way to do anything helpful from download mode? I'm not too concerned about losing data, so flashing a new ROM is fine by me.

hi
Seem like flashing a new firmware may be the reasonable option...
Try flashing first with home_csc if you know what your CSC is at the moment..that way you may avoid losing your data
if that option is off the table...then use CSC and flash/ format your phone...

Pay attention to step 6 if you use CSC

Thank you for the response. While I was downloading the ROM I came across "Vysor" and was able to use it to control the phone. Using it I was able to get the phone to power off and get into recovery mode. I wiped the cache partition and uninstalled the Tether app and all is good now. Now I just have to decide whether or not to cancel the RMA that Straight Talk is sending me...

[Q] Cannot get download mode - HELP

I was trying to get 2.2 on my captivate. It got hung and after about an hour, I powered down phone (battery out).
I'm now getting [phone... (!).. COMPUTER] picture
Trying to get back to stock ROM 2.1, but I cannot get device in download mode
I had to use adb to get in download mode originally.
Is it possible I got a phone that doesn't go into download mode based on button combinations? If so, what do I do?
Unplug your phone from USB
Pull battery
Close Odin
Open Odin
Put in battery
Hold both volume buttons (NO POWER) and plug in USB
Hopefully this gets you into download mode
Still Fail
I've been trying that, but without open/close of Odin.
Still failed when I added that step.
get to that screen again: hold volume up/down and power at the same time.
When the screen goes black, then release power button but keep holding down volume up/down

Yes, and remember to keep the volume buttons pressed in while plugging in the USB... I always hold them in until the droid/caution sign comes up.

Try the methods prescribed. There are several minor variations but you may have a phone that doesn't do three button recovery. In order to tell, we need some history on your phone. What is the RF Cal date? Were you able to three button into download before? Do you know if it was one of the ones that had the three button problem?
autocorrelation,
I tried that with the usb cable plugged in and without it plugged in.
Still no good.
joeybear23,
I've been trying that all afternoon. Probably about 50 times.
ianwood,
How do I get the RF Cal date? I don't see it under the battery where the S/N is located. I tried to do 3 button recovery to put phone into download mode when trying to install 2.2, but it wouldn't work. I had to use "adb reboot download".
I've never tried it before today. The only issue I've had was that it could NEVER connect to AT&T server to check for an update.
can you get it into recovery mode?
no recovery
No. It won't go into recovery mode either.
The only thing it WILL do is respond to all 3 buttons being pressed by the black screen flash after about 8 seconds.
If you keep holding all 3 buttons will it flash again after the initial black screen? Try releasing the power button and keeping holding vol up/down after the second black screen.
If I keep holding all 3 buttons, it just keeps flashing.
Also tried to let it flash twice (and even more) and releasing power right when it goes to black 2nd (or 3rd) time. Also tried releasing power half way through black screen, and right before black screen re-appears and also just as the screen powers back up. None of them work.
I ran into this yesterday and about freaked out. Don't panic - apparently one of the guys had this happen to them a lot. Take a deep breath, have ODIN open, plug your USB cable in, hold the volume buttons down at the same time, press and hold the power button till you see the phone to computer, and let go. You should get to the download screen again. Good luck; sucks when something like that happens and you don't know what's going on.
I know this wont help much, but I have one of the no 3 button phones, and after 20 minutes of trying all these methods, it did go into d-load mode. Unfortunately, I don't know exactly which combo I used since my brain went into overload when I finally saw the triangle appear. There is hope though, and please PLEASE post which one works for you(I'm afraid to mess with mine until I find a foolproof method)
I had a phone that wouldnt respond to ANY 3 button combo I tried. I bricked it (sorta on purpose) to the phone-!-computer screen and went and replaced the phone at AT&T (under the 30 day deal).
It didnt initially work with the 3-button but after the JH7 OTA DL mode and recovery mode work perfectly now. Also, GPS has been completely spot on when testing on my motorcycle with the phone in my backpack running my tracks.
If you are under the 30-day return policy, bring it in and come up with a good reason as to why they should give you a new phone. If not, then you're sorta SOL....

This method just saved my butt!!!
I have never had trouble getting into recovery or download mode until today when I did a dumb thing. The phone would lock at the ATT screen when trying to power on and if the phone was off and I plugged it in to charge it would freeze and the circle logo that comes up before the green charging battery does.
Every method of getting into download or recovery failed up till now.
Thanks Zilch!!!
Hey guys gonna move this to Q&A.
I had this problem a few days ago after updating to 2.2. I tried every single button/usb/battery combo and nothing worked. FORTUNATELY I was within 30 days of purchasing it (I guess there's a silver lining when diving right into "hacking"), and I brought it to the store with the box and receipt and just told them it gave me an error when turning it on (played dumb) and they swapped it out without even testing. If you're over the 30 days then I think you're pretty much SOL... gotta pay for a replacement.
bricked
I declared it to be bricked and took it back to the store. I have only had it 2 weeks, so I basically pulled the same move of playing dumb and they gave me another one without any problem.
I'm wanting to try to see if I can put it in recovery mode and/or download mode with the buttons without even attaching it to anything, but now I'm paranoid about bricking it.

Buddy, we need you to remember I'm in the exact position, no combo works and I bricked it after trying to load 2.2
Going into recovery or download will not brick it, its only everything after that point that might get you bricked.

SERIOUSLY bricked my Galaxy S 4G :(

Long story short I was trying to install a new ROM via CWM and it would never actually overwrite my recovery image (when restarting in recovery mode I would always see the OEM screen with blue text). After doing some searching the interwebz I found someone with the same issue and it was suggested to Re-Partition their phone. I found a PIT file and I ran it using Odin, only after it was complete the phone will not even turn on. It won't power up using the power button, it won't go into recovery mode, it won't go into download mode. It is COMPLETELY not working!!!!
Am I royally screwed? Do I have any options than just to tell T-mobile that it stopped working and pay my $150 deductible to get a new one????
If its completely cant turn on, your phone is definitely bricked. Well you should go to the store and act dumb. Just to wish you good luck just in case they found you voided your phone's warranty
After doing some more googling around I found that I was able to get some red assembly text to come up on the screen by holding Vol up, Home, and Power simultaneously. The computer played its USB found chime, and then I was able to power off and get into Download mode.

[Q] [Q} Broken Power Button, Phone won't go into Recovery or Download Mode

The power button on my phone recently has stopped working. I need to get it warrantied, but I am running CM 10.2. I need to Odin back to stock, but I can not get into Download Mode or the recovery. When I go into Download mode, the initial screen pops up, the one where you choose to hit up to continue, or down to reboot normally. After I hit up, the screen goes black and nothing happens.
I really need to get back to stock, as Bestbuy are being dicks, and demanding I do a factory reset before they send my phone in.
Anything? I still need help on this.

This has been covered at least 10 times in the past few months we need a sticky. Take your battery out hold your phone so the power button is facing a table or floor and slam that side a few times it should work again (Temporary). You might need to hit it on the surface really hard 10-20 times before it works. Just not to hard or else you might crack the screen. I used a mouse pad to soften the impact. This trick no longer works for me so I ripped the button off. After about a month of doing this I needed to use things that would only hit the button to make it work. About a month after that nothing worked so I just took it off the motherboard and now boot from a off state by plugging into the wall and enter odin mode deny the prompt and it kicks me into a workable state.

I can get into the system just fine. When I go into the recovery or download mode, it doesn't stay in that mode. I tried the banging thing, and it made my power button go from intermittently working, to not working at all.
keep doing it until it works. The button is sticking that is why it reboots/stopped working.

It sounds like your power button is physically broken, and it is activating intermittently, which is stopping the phone from entering download mode. My only experience with this problem is my own phone but ultimately mine got so bad that I had to rip the button off the motherboard, as ThePagel did. Your symptoms sound the same as mine.
You can try this procedure to get into recovery, which works for me without a power button. You will probably have the same problem you are having now with the phone rebooting on its own before you actually get into recovery, because the power button is activating.
1. Take the battery out of the phone and unplug it from USB power.
2. Plug in USB power.
3. While holding down the volume-down button and the Home button, insert the battery (this is a little tricky).
4. The phone should start and warn you that you are entering Download mode. If you want to use Odin to return to stock, do that now.
5. If you want to get into Recovery instead, press Volume Down to reboot and then *immediately* push and hold Volume Up and Home simultaneously. The phone should reboot into recovery. Mine does.
If that doesn't work, and you can't get a new phone without returning it to stock, then prying the power button off the phone's motherboard may be your only solution.

S8 Plus Recovery Auto Boot

Hi guys, this is my very first thread so here goes nothing,
I recently damaged my S8 + power button and it is no longer operational, however i have been able to boot to download mode and reset device after it going flat and not turning back on and staying in a bootloop while plugged in. Any way so my new problem is that it went flat again and i plugged it into charge and it automatically boots into recovery mode and when i manage to get it into download mode pressing volume up or down does not work. Any way to fix this and get my phone back up and running?
I can definitely see that being a ***** because you need the power button in sequence with Bixby and a vol button to get to download mode or recovery. Id prob root the phone and install quick shortcuts app that gives you on/off/reboot/restart/ options it might help you. But replacing the power button is a simple procedure and I'm sure it's very cheap to. Id fix that button and problem solved.

Factory reset A7 2018 to remove lockscreen

There is an A7 2018 with lockscreen on, but the owner don't remember it. So it need to be remove by resetting the phone. However, unlike all the video on the net, this phone actually at the screen where "password is required after restart", not the actual lockscreen itself. This is where the problem lies. I've tried getting into recovery mode with the button combination, but the phone won't get into it. There is no turning off the phone, because it requires password to do so. I've tried everything, vol up+power, vol down+power, vol down+power and when the screen turned off switch to vol up+power, and repeat them all in case I didn't time it right. The phone just won't boot into recovery. Also, it won't goes into download mode as well.
So, was it the phone's security that was blocking me, or I just haven't tried everything yet. Spent half a day working on this phone, ended up nowhere.
Forced reboot is done by holding VOL DOWN + POWER for around 7 seconds. Once it's rebooting, hold VOL UP + VOL DOWN and plug usb. You have to do this when the phone is off and not yet vibrated when turning on.
I will try to find some way to help, but force reboot should work ALWAYS.

Force reboot does worked, every single time. But it just won't reboot into recovery. Thats the problem. Can't reset the phone without going into recovery. Or is there any other way?

Its off alright, tried checking it with command prompt and nothing shows up.
I always leave service centre as the last resort.
,.... There is "a phone". .... And the owner " does not remember the password"....
These things make my alarmbell go off.
I don't say you stole this phone or anything, but I am not going to teach you how to unlock safety on a phone because there is a good reason that safety feature is there.
Contact a service centre and good luck.

Oh come on, there is not a single thief in this world that will lose time to check forums and waste hours like the colleague above or me ,trying to fix a phone ! All with gsm repair services had stolen phones in their hands for sure ! If one customer comes and says give me *lets say half the price for a s9* for a s9 , you wouldnt give them the money and buy the phone? of course you would ! We are all humans trying to make a living. Extremely few people would hold back and ask questions ! And sometimes , when buying phones, you can get some that are stolen, can`t catch the thief, can`t recover your money ,unless you remove frp, bypass security, remove icloud , thats just the way things work ! no point in hiding behind a finger. You sometimes get rekt ! and buy stolen phones without even knowing, or willingly buying, because if not, the competitor will buy it and ruin the market price for you ! Good luck to you all !
