S7 won't boot (Stays at the pulsating samsung logo)

Hello XDA friends,
I hope to find a solution for my problem with my Galaxy S7.
I've flashed the newest Version of Android with Smart Switch, but it won't boot to Android. It just starts "Samsung, Powered by Android" then switches to just the Samsung Logo then gets hot and after 5-6 Minutes it vibrates 2 times but nothing is showing on the screen except the Samsung logo.
I tried everything, rebooting it several times, multiple tries with factory reset. Nothing helps.
Hopefully you guys can understand my broken german english.
This is what the Download Mode currently says:
ODIN MODE
DOWNLOAD SPEED: FAST
PRODUCT NAME: SM-G930F
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Samsung Official
FRP LOCK: ON
Secure Download: Enabled
WARRANTY VOID: 0
RP SWREV: B:1 K:0 S:0

I have a similar issue to this, no fix found yet though.

Flash stock with ODIN 3.12.3

^^^^ Flash stock OS with Odin, if Odin returns with FAIL straight away go into TWRP and format System and Data then flash stock OS

I already tried 7 different stock roms, all have the same problem.
And I cant flash TWRP because the FRP Lock is on. And because I cant boot into Android I am not able to switch it off.

So far, i've tried these firmwares:
Smart Switch - Nope
SM-G930F_1_20170203142713_MOB_fac - nope
SM-G930F_1_20170210110639_6j1nt9xw0b_fac - nope
SM-G930F_1_20170418223200_pf0e8ktcz8_fac - nope
G930FXXU1APB4_G930FVFG1APB2_MOB - nope
SM-G930F_1_20170329175552_qghvj8op9t_fac - nope
SM-G930F_1_20170317121226_ipt5jsw6zo_fac - nope
And on every firmware there is the same problem. Pulsating logo, but nothing happens except the phone gets warm for some time and then cools back down.

I see all the firmwares you have tried have been from 2017, so I assume are all Nougat?
Tried an older Marshmallow firmware?
This one is BTU Unbranded United Kingdom MM for G930F
http://updato.com/firmware-archive-select-model?record=2877DF1921A611E6949E0CC47A44B7B2
Also have you tried using CSC rather than CSC_HOME?
Are you using the correct CSC for your device?
Have you tried checking Repartition in PIT section of ODIN?
Finally are you using ODIN 3.12.3 minimum version?

Tried an older Marshmallow firmware? Yes (Stays on the "Samsung powered by Android" logo)
Also have you tried using CSC rather than CSC_HOME? Yes
Are you using the correct CSC for your device? Yes
Have you tried checking Repartition in PIT section of ODIN? Yes
Finally are you using ODIN 3.12.3 minimum version? Yes
So far, no success

Have you got access to a different PC to flash from?
And a different USB cable to flash with?
If not a different PC, try a different USB port, if using 3.0, try 2.0 and vice versa

Tried it on a different pc and on different usb ports, I even tried multiple versions of the rom on multiple ports.
Still no luck

Sounds like it might be time to RMA unfortunately

I can't send it back, since I got it from a friend and he had a screen repair from a non-samsung partnered shop.
So the warranty is void :/

I have had this problem in the past.
You need to download Samsung KIES 3
(Version 3.2.16084-2)
Select Firmware Upgrade & Initialization from TOOLS at top of APP.
MAKE SURE YOU CONNECT AND DISCONNECT WHEN KIES TELLS YOU TO.
Make sure you have your exact model (example: my model is SM-G930FD)
Make sure you have your Samsung Serial Number (example: NOT ACTUAL S59K432SLQF).
IF YOU DON'T HAVE SAMSUNG SERIAL NUMBER, YOU MIGHT HAVE IT ON YOUR RECEIPT OR BOX.
IF NOT, PERHAPS YOUR CARRIER CAN GIVE IT TO YOU.
DON'T WORRY ABOUT ANY SMALL SCREENS THAT POPUP AND SAY ANYTHING ABOUT NOT BEING SUPPORTED -OR-
THAT SMART SWITCH IS FASTER.
Eventually you will get to a screen that says
"The device can be initialized to its original settings.
All settings and data will be deleted, and the latest software verison will be installed.
Do you want to proceed with the firmware upgrade and initializastion? (OK CANCEL)
The app will download the firmware and then apply it to your phone.
Do not touch the cable or the phone while the process takes place.
When done, your phone will reboot as a new phone.

I did everything as You and Kies explained, sadly tho this also does not work for me....
This is so weird why is it constantly trying to boot and get stuck at the logo? :/

When you are in download mode, press and hold down volume, Home button, & Power key. When phone goes dark, switch from volume down to volume up, & keep holding power & home. This might get you into stock recovery.

I can access the recovery, but Wipe/Factory reset also makes no difference. Like i said in my first post

You may be able to find a local repair shop by searching through Google. OR-you can try searching for craigslist. Org and your city. Then lookup repair of your phone.

Have you tried flashing each section of the ROM one by one and attempt a boot after each?
Can't really think of anything else, it sounds as if the internal storage is having problems, as mentioned above, a repair shop could be your only hope now, but I already know they'll tell you the motherboard is faulty (even if it is not) unless you know of a reputable shop that doesn't BS customers for £

Try calling Samsung and ask them how much to reflash out of warranty.
It shouldn't be that much....

Help with Flashing TWRP

Hi xda, so I need help flashing TWRP on a Sprint S5. The situation : I'm trying to help a friend out who needs to backup absoultely everything on his broken S5, but in order to do that I need TWRP which I'm having trouble flashing. Odin just gets stuck on "Setup Connection" every time, and I don't know how to fix it.
The phone is in very bad condition right now. The screen doesn't display anything or respond to touch as far as I know, and the usb port seems to on the verge of dying as well. He says he has to to bend it just right to even get a connection at all, but once he does it seems like it doesn't just randomly disconnect, so there's that. He also did not have usb debugging enabled before he broke the phone, and the screen has a lock as well so we can't just go and enable it using a mouse or something.
I've flashed using odin before but obviously he doesn't have another samsung with him to test whether it's computer or the potentially damaged usb port causing the problem. Testing with another computer is not an option unfortunately. Same goes for the usb cable, this is the only one he has. I'm pretty sure the cable isn't the source of the problem though.
So far I've tried uninstalling and reinstalling the usb drivers, using the other usb port on his laptop, using another version of odin (3.09,3.10,3.12.3 doesn't seem to matter),and another version of TWRP as well, running odin as administrator, going into download mode first then opening odin, and even "Home + Vol Down + Power to get into download mode but not pressing Vol Up to confirm until odin is up and running". But no matter what I do it's always stuck on setup connection.
Does anyone have any suggestions on what I can do to fix this?

If the phone is rooted download an app called Flashify. Download the img file from the twrp website and install with the app. I have had good luck with this.

Samsung S6 Boot Loop

Hi,
Apologies if this has been asked before, but I've done a relatively thorough search and I can't find a solution to this problem.
I have an S6 (SM-G920F), It was playing up for a few weeks before this, not charging well, and what not, thought it was a cable/hardware issue. Then it stopped working entirely. Initially when it was plugged into the wall it would say it was 91% charged, but if you tried to turn it on it would turn off, and reboot into the charging screen.
I've done quite alot of reading and I've ended up flashing it with Odin (I have a single .md5 file, which i've loaded onto the phone via AP) using the most recent FIrmware UK EE for the SM-G20F. This was successful, however now it only loads the Black screen with white text Samsung S6 powered by android screen and then goes blank and back to the white text screen.
I downloaded an alternative firmware (the one previous version), but this has had the same effect. I've tried to repartition with odin, but this fails.
1.) Is there anyway I can fix this?
2.) If not Is there anyway to remove files whilst in downlod mode?
3.) If I cannot fix it or recover my data, is there anyway to wipe the data securely from my phone so I can sell it for parts?
At present, I can't access recovery mode, only download mode. But whilst Odin communicates with the phone in download mode, I can't seem to access my files from explorer?

1. I would say you'd have to clear cache, immediately after flashing the firmware with Odin, but to do that, you'd have to get to Recovery Mode first...
Why can't you get to it? Does it just start trying to boot nornally? Because if so, it's just a matter of timing it. What I do is... hold power+home+voldown to get to the screen that asks me if I want to get into Download Mode, I press cancel, and immediately start holding power+home+volup until I see the bootsplash screen, and release the power button but keep holding home+volup, and it gets me to Recovery every time, even when I have difficulties such as this.
2. Not that I'm aware of. BUT you could flash TWRP with Odin, and if you then can manage to get to Recovery, you just need to plug your phone into a computer, and your phone will show up in the computer as a device/disk and you can freely remove stuff from it.
If... IF this were to work, I would suggest downloading a stock-based ROM and flashing it. It's far more likely to work properly and bootup without issue than the firmwares you can get, and it's far less much of a headache to do.
3. Nope. There are apps that can wipe data securely (such as Shreddit which does it according to military standards), but it can't be done from Download Mode. There may be some script that could do it in Recovery Mode, but I doubt it.
I mean... technically... you could flash TWRP, go to Recovery, move to your PC all the stuff you want to keep, select the wipe option in TWRP and then transfer randomly generated data from your PC to your phone until it's full - there are many apps that can generate such data. It's not something you could pass off as very very secure, but it should suffice.
I seem to always keep going to trying TWRP - so, you know, give it a shot.

Thanks for your reply! So after flashing it goes straight back into the boot loop. Weirdly if its plugged into my laptop it spend about a second or two on the "Samsung Galaxy S6: Powered by Android" screen before plunging into darkness and shortly after repeating the same message. However if I plug it into the wall it spend over twice as long on that screen before repeating the cycle. It never goes any further.
I've tried your suggestion about perhaps its timing for recovery mode, but even if I go straight from cancelling download mode to trying the power, up and home key it doesn't go to recovery. I've tried a variety of timings both plugged into my laptop and plugged into the wall to no avail. If the phone isn't plugged in, it literally won't do anything whatsoever, won't even hint at turning on.
So Next I tried flashing it with TWRP via Odin and nothings changed, exactly the same bootloop and I still can't get into recovery mode.
I'm starting to think that sadly this phone my be beyond repair! Thanks for your help though, much appreciated.

Hi! I usually run out of my bootloops like this:
try this:
1: go to download mode, and press Power + home + volume —
2: As soon as the screen turns black, continue pressing Power and home, quickly release "volume —" and press "volume +". This will get you into recovery mode.
It always worked for me, so I wish the same for you. Good luck! (And sorry for my bad english)

Hi Vinicius,
Thanks for the suggestion. Unfortunately it didn't work, I even tried flashing it back to a standard ROM from TWRP, but it still didn't do anything, just back to the Samsung logo and the loop continues ever more!

Hi, I have this problem as well.
Originally I had TWRP and root flashed into my phone but for reasons I needed to remove root.
So I followed the Odin route stated here "Mobikin how to remove root from android" (I can't post links but this should be the top result when googling)
However I didn't know if the recovery/boot should have went into AP or BL on the Odin menu and googling didn't give me any answers so I may have tried both....
Right now I tried flashing TWRP and I can't seem to boot into TWRP as well.
I was able to get into recovery mode but clearing data/cache didn't fix it for me.
EDIT: I managed to flash in another stock rom and it boots into the SAMSUNG logo but gets stuck there. I already went into recovery mode to delete data and cache partition but it still doesn't boot.

Same experience. For all those 6 years that I used this device, the wifi was okay until now. It (wifi) is very buggy (turning on and off, and sometimes won't turn on at all) so I restarted the device, then bootloop happens. I flashed the stock rom via odin and clear data and cache. But it is still bootlooping. I think this is the sign that I need to replace my phone IF I couldn't find a fix to this.

MobiControl failure leads to locked phone

My company uses an app called Mobi Control (an MDM) to limit and "lock down" what employees can do with their phones. Here's the problem...the app is just crashing on one of the phones. So I cannot access it remotely and reset it from the computer. I cannot push updates to it. I also cannot reset it from within the phone. If I try to enter Download Mode, all I get is the "Binary Download Mode is blocked by MDM. Phone will reboot in 3 seconds". I have also tried the following:
1) Put it in safe mode and tried to remove or reinstall MobiControl, no go.
2) Use ADB to sideload anything or factory reset, no go.
3) Set it to factory reset after entering the passcode wrong 12 times, it just keeps asking me to try again, no go.
4) Use the USB jig to go to Download Mode, same blocking error, no go.
5) Reset or push a new firmware or anything else using Kies, no go.
6) I can't disable MobiControl as a device administrator from within the phone, the option is greyed out, no go.
7) Push anything with ODIN, but because it is not in download mode it doesn't work, no go.
I'm looking for any help as this phone is a brick right now because of it. I need to give it to a different employee but can't set it up properly because of the blocking. MobiControl claims there is nothing they can do. If that is the case, I strongly urge anyone to stay away from Mobi or any MDM software. I've seen people have similar issues with Airwatch.

You have to try and remove it from being and administrative app

Cannot do that. Mobi won't allow it.

I would even be willing to send this to someone to see if there is someone smarter than me that can factory reset this.

My company use Airwatch so i'll go have a chat with the guys in IT tomorrow and see how they resolve the same issue with our handsets.
You talk about it crashing but then you say you see the admin option greyed out? So can you actually start the phone or not?
Also have you tried, google Find My Device and factory reset it from there? I'm sure this is a loophole with this type control app...

I should clarify...the app crashes when the phone boots or any time you click the icon. immediate crash. The phone boots fine. Did the IT guys ever offer any ideas.

hi friends i did it successfully and get ride off mobi control administer on galaxy tab E SM-T378V by using odin last version and it,s latest firmware.
but important point is that in odin first use BL file due to omit all info on mobile and mobile goes to boot loop .
then use odin and enter all BL,AP,CP,HOME CSV .
THEN START

Unbricking options

I have a conundrum. I bought an international S10e so I could root and run custom ROMs, even though I live in the US. While flashing with Heimdall, my USB controller flaked out and the flash failed hard. It left the phone in such a corrupted state, that it no longer will go into download mode or boot into recovery. When connecting it to a computer, it just goes to a teal screen that says the following:
An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software.
Click to expand...
Click to collapse
I installed Windows, the drivers, and the Smart Switch software, but the program refuses to see my S10e as a valid device for emergency recovery or otherwise. I took it to a shop to see if they could perform the reset, and they told me that Samsung US refuses to give them the necessary files due to it being an international model.
Are there any other tools I can use to perform this reset, or do I have to mail it in to Samsung?

it will go back into download mode again!

I have tried all that many times. The phone will not go into download mode. Unless there is a way to perform the reset that it suggests without download mode, it is dead and I will have to mail it in to Samsung and fight with them about it. Are there really no consumer-available tools that can do this?

I would gladly buy this off you if you don't fix it. Feel free to send me a pm as I'm never on here.

It's just soft bricked lol. I've been at this exact screen myself (S10e exynos). Just download Odin, Samsung USB drivers and stock ROM. Connect phone to PC, and Odin should detect it right away if I remember correctly. If not, hold power + volume down until the phone shuts off, then quickly plug it in while holding bixby + volume down. Try messing with it until Odin detects it and then just flash stock. I can assure you, it's fixable, nothing serious.
