While on vacation my S7 locked up, so I force rebooted it, except it didn't reboot. Instead it stopped turning on at all. Only when I put it on a charger it randomly decides to boot into download mode without me doing anything. While in download mode it doesn't show any details about the phone in the corner, just do not turn off target. You guys have any idea whats going on here or how I can fix it? The phone has never been altered except for substratum themes. It worked fine before the crash.
Tried flashing the latest firmware files in Odin, but it keeps getting stuck at: "Getting PIT for mapping." I tried adding the correct PIT in the options but it isn't helping.

The unit has been used for about 2 months and remains quite new. It was quite stable before. Yesterday night, about half an hour after plugged in for charging and with WiFi Hotspot turned on for sharing 3G data to another netbook, the unit suddenly rebooted itself. It then stopped at the start-up screen and remained there for several minutes. I kept holding the power button for a few seconds to turn it off but it then automatically reboot itself afterwards, and stopped at the start-up screen again. It means that even complete turning off is not possible.
Trying to enter into recovery mode showed the following few lines:
# MANUAL MODE #
-- Updating application...
Copying Common Apks.
Click to expand...
Click to collapse
and then it automatically rebooted again. It means that it can't enter into recovery mode normally.
It was possible to enter into download mode. And it was the first time this machine went into download mode. I run Odin Downloader and flashed the official stock ROM. After showing "Pass", the device rebooted itself. Unfortunately, it still stopped at the start-up screen, just showing "Samsung Galaxy Tab 7.0 plus". It is really troubesome. I have experience playing several Android devices before and it is the first time I face such troublesome problem.
The device is an official product. The biggest problem is that the original purchase invoice was lost and most likely that I couldn't get official support, repair service or replacement.
May I ask if anyone would kindly provide me some help or advice. Thanks!
Instead of going into download mode go into recovery mode and see if there are any errors. Your scenario is sounding very similar to the one I had in the past.
I just ran into a nasty snag at boot logo as well. nandroid, stock kernel and factory reset were no help. Try Odin back to Stock, it still may not get past boot logo, hold vol up and power to get into recovery and factory reset. Hope it works for you.
Unfortunately I was unable to get into recovery mode even after odin flashing stock ROM.
It rebooted itself a few seconds after displaying some lines of text. I can't see the normal recovery menu.
Hello everyone, I've got a S6 G920F, that I tried to do everything to. Here's the problem and what I did:
First off the phone never turned on unless I put it in the charger and it would display the "emergency mode" screen. I switched to download mode while its attached to the computer, tried to flash stock firmware with no luck, until I found a PIT file that I flashed via odin and revived the phone that it got me the "Samsung" logo. But still it would turn off. I did efs repair and phone stopped turning off but still was stuck on samsung logo. I then came across this "choimobile" 4 file firmware and flashed only BL and AP(as they said) and phone finally turned on, started optimizing apps, finished and entered the system, I went to check if IMEI is intact from settings, and it suddenly rebooted, to system again, except this time for few seconds and reboot, then it got stuck on bootloop on the "samsung". I've been stuck here with nothing left to do.
Here are the links I used:

Would appreciate any help thanks in advance.
P.S. I did wipe data and cache using recovery numerous times
I have been given an S7 SM-930FD [Dual Sim] that was supposed to be bricked. It wouldn't boot into anything but I have successfully got it into download mode and been able to successfully flash a stock ROM downloaded from Sammobile [several times] with no errors. Each time I have used the full set of AP,CP,CSC files and the previous owner is not sure what ROM it was on or what he tried to install. I have tried different versions of the firmware for this model for various android versions and regions simply to try and get it to boot, but without success. I have tried HOME CSC and CSC files too.
But each time it starts to install the update / reboot it hangs. Either when it installing the update on the blue screen with the robot and its "erasing" - small rotating symbol just stops and nothing happens OR it loads to the GALAXY S7 normal boot screen then hangs.
When it hangs it will only respond to one key combination Power + Vol Down. It then "switched off" and will not reboot in any mode. When I say "switched off" I mean the screen goes black. However if I then connect the charger, it won't show the charging symbol UNLESS I leave it for a few hours and the battery goes flat. It will then charge and I can boot into download / recovery mode but normal boot starts installing the update and it will hang all over again. On one occasion it hung with and black screen and blue flashing light but again no key combinations worked and I had to wait for the battery to drain.
Also tried Smart Switch Emergency Recovery. Even with the drivers freshly installed it does not recognise the phone, it does accept the model number during initialisation, but once the S/N is entered it comes back and says it can't find the model, S/N or IMEI in the database!
I have researched the web for hours and watched every relevant youtube video and tried their suggested key combinations etc and they just don't work.
So I'm hoping someone can help me resolve this frustrating situation, not least because of the delays between attempts!
Presumably as I can consistently get it into download mode there is a solution out there somewhere???????
What am I doing wrong? Should I be looking at a custom ROM or trying something else?
All help appreciated.
Anybkdy know why my phone just keep restarting randomly, even sometimes my phone keep restarting at "samsung galaxy s7",not going to boot animation
Friday my phone went crazy and just started rebooting. Can't do anything it's just like it's stuck in a boot loop now. I'll be sitting there and it will just start rebooting. I have to do the pwr+vol. dwn to be able to shut it off. I can't even get it to stop in safe mode. I have no idea why it started doing this.
Does your device have root?
Are you using any kernel tuners?
If you have something set up incorrectly or levels set too high will cause boot misbehavior.
Ensure that all your firmware partitions are the same build. Also ensure that all of the apps you use running are fully compatible with your device.
Had it for 3 years now, it first looped in October 2017, broke all the sensors but has otherwise been working fine since. I also rooted it about 7 months ago in case that makes any difference with recovery. During both of these loops I have been unable to reliably get into recovery/download mode. I left it alone for an hour earlier today and came back to find that it was somehow in Odin/download mode with the text in the top left but still on the boot screen. So I plugged it into my computer, it was detected and then I flashed it with the correct G930T firmware and home csc. Got the success message in Odin and it seemed to be working but it was just stuck on the boot screen now. So now I've just been trying to flash it again with the other csc but it has been failing for a lot of different reasons and I don't know what any of them mean. I did manage to get it to power on a lot more reliably and into download mode, but still having problems. The biggest problem is when I get to either the download screen or warning screen, the screen suddenly gets all glitchy and I can't do anything. Whenever that happens it also shuts off after 10 seconds. This also happened on the Smart Switch emergency recovery screen when I cancelled a stalled flash and then tried to flash it again from that screen. I've also gotten errors when trying to flash from the download/boot screen. The ones I can remember are "unsupport dev_type", "secure check fail : tz eMMC write fail : tz" and "secure check fail : hyp eMMC write fail : hyp". I can't even find anything else on these errors and have no idea what they mean. I also have no idea how it is getting into Odin mode on the boot screen but so far that is the only way I have been able to do anything since I can't get into download mode the proper way. Lastly I tried to check in Smart Switch to recover it but it says the device is unsupported and there is nothing in emergency recovery.

When you flash with Odin tick "'re partition" in Odin options.
When "pass" appears disconnect phone from pc. Force reboot by holding home+volume down+power.
As soon as screen goes black press volume up while keeping home and power pressed. When recovery menu appears choose wipe / factory reset. Then reboot.
What is obviously very important is you are flashing the correct firmware for the device in the first place.
