Help requested for bringing S7 Edge back to life - Samsung Galaxy S7 Questions and Answers

Dear Learned ones,
I recently purchased a second hand Samsung S7 Edge phone, only to find out that it has a software KingRoot installed in it. I went into kingroot and then pressed some options to unroot it and then deleted kingroot app thinking it would have done the job but apparently not.
Now I have been trying to follow some youtube videos how to factory restore the phone but am stuck. The phone isn't simply going into download mode at all. I tried pressing vol down + power + main button but it simply does not work.
I would greatly appreciate if you can please help me with how do I go about restoring it to the factory mode.
Peace

Hi mate
Sometimes is tricky to get into download mode , when system is not 100% ok timing becomes an issue, keep trying it should work
Once there just flash a fresh firmware

Sometimes holding Volume Down & Home & Power until the phone reboots twice will work if doing it only once fails

Thank you, both for your replies and assistance. I have tried holding all three buttons down for good minute but nothing happens. It feels like that the screen lights up a little and then goes off again. I have been trying it over and over again few times but nothing happens
When I do it few times, it then comes back saying Android is starting... Optimising app XX of 102 and then starts normal again.
Is there a way i can insert two pictures here for you to see the main screen?

Hard reset not working (among other things) on samsung captivate - please help!

I got carried away there, so I'll summarize:
Yesterday most of the apps on my phone started crashing. I tried clearing from recovery mode, but nothing went away. Today, I've tried to reflash to stock to get the phone completely clean, but also no good. Even using master clear and reflashing the rom doesn't clear the phone out. Everyone says it works, but the applications are all still there after the reboot, except now they all crash, including launcherpro, leaving me no way to do anything at all on the phone
I'm desperate because my phone is currently unusable. Please help!
Update: I found another method for doing it, listed below, which worked. Still no data though
Anyone have any ideas what might have happened/how I can fix?
2.- :::: CAPTIVATE HARD RESET :::
captivate must be powered OFF to perform this reset, If the device is on, turn it off
- Press and hold both volume buttons + -
- While holding down volume buttons + -, press the power button while maintaining the volume buttons pressed in for around 5 seconds
- Release volume buttons but, keep the power button pressed
- you'll see at&t start up animation release power button
- menu appears
- follow instructions using volume buttons
delete cache data, press power
delete all user data, press power
reboot system, press power
*** (optional) turn off the phone, put my sim card back, turn the phone on
Holy crap... I don't know what's wrong now... I did "Delete user data" and "delete cache" from the boot menu, and STILL everything is there!
What is wrong with my phone?
reflashing to stock... hopefully this does the trick...
ok I went through the process of flashing to stock, and it said it worked, but the old applications are still there!
Now, when I reboot, I get a ton of force close messages; presumably everything that normally would be launching on startup.
how do I actually clear this device and get it back to stock?!
for reference, here's the page I used:

Hey there,
I'm afraid this won't help much, but in the end I had to call the AT&T warranty department and get a replacement phone. There's a 1 year on the phone, and while I had to jump through some hoops, they did replace it. If you're within 30 days then you're definitely in luck, as you can take it back to the store you bought it at
Good luck!

[Q] Power Button Not Working

Hi guys,
I have a little problem where my phone's power button will not function in any way, long presses, short, almost embedding my thumb in it, all to no avail. This is doubly dissapointing as I have just installed the latest dexter plus patch to fix the problem. I still had the problem on the previous version and I thought a clean start may fix it. The only way I can get the screen on is to press the media play button! Which of course isn't doing anything on dexter.
Hunches:
I have been playing with a light sensor program and using a 3 second press to turn the phone off, I am only thinking this is related as when I re-installed then turned off the phone using a battery pull, that now the media gallery button will now not work at all, so that is a change.
Second, the power button is buggered. Seems unlikely as everthing feels normal, no big drops have occurred from heights, and the button is travelling in and out as usual.
I have also noticed that as soon as I re-insert a battery that the phone starts immediately, the M pops up as if it is already posting. So maybe it is stuck down?? Again, I don't think so, as the mechanism is working per usual.
If anyone can help it would be fantastic, you guys haven't let me down yet, and this thing is purring, but unfortunately I cannot use it lol. Just my luck.
Thanks in advance
another thing, still not solved
Another thing is happening, the phone screen turns on "after" pressing the power button, it may be once or a few times, and then pressing the gallery button.?!?!
Also, at random times it plays a podcast on my phone, the exact same podcast, and from the start, though the duration may be a few seconds then repeat, or it may go for ages, its quite a rude podcast too which has caused me to throw my phone under the car seat to shut it up when people have been trying to talk to me, as you can imagine its quite embarassing.
There are no services or apps running that I can find related to music, it may happen after pressing the camera button, or opening a website.
It is still going really fast though. And I have also reinstalled the light sensor program so I can turn it on and off without causing damage to the power button.
Thanks again everyone.

please clarify
sure, so the only way I can get the screen to turn back on, after turning off as per display power saving preferences, is by pressing the power button, maybe a couple of times, then following that up by pressing the gallery button next to the shutter button, pressing the gallery button doesn't seem to be working to turn the screen on now, but this combo is.
I hope that helped.
Cheers.
EDIT:::
The gallery button alone is working again. sorry guys.
You might just want to reflash it to stock to see if this resolves the problem.
Yeah I think I may have to.
Before I do., I was reading a post on a different forum where another person was having a similar issue. They seemed to solve the problem by using rom manager to boot to a manual restore menu where there was a button tester section, after using it the power button worked for them. I tried but after resetting it displayed a triangle graphic then rebooted.
Is there any way to do this with our open recovery program or any other utility to test the functionality or maybe reset the button or apply a patch etc.
Thanks again :-D

Getting Frustrating
Alright so I followed your advice on your videos on how to reflash to stock, so of course my bootloader does not show up the same as yours on the video. I can get to the bootloader fine, using the button combo or by using quick boot > bootloader, both have the exact same result, the boot loader screens as follows:
Bootloader Fastboot mode
80.89
and that is it....
Also, my computer using rsdlite does not acknowledge the phone, not omap drivers loading etc. Followed your instructions exactly.
This is frustrating me to no end lol.
I am guessing that because I can get to the bootloader with combo no problem, that the buttons physical connections are working.. At least thats a positive.
Can I flash to stock with openrecovery? Or maybe to an earlier version of Dexters froyo? Other ideas?
Any help would be much appreciated guys, trying to use this phone at work with light sensors to turn off screen is not as easy as they say. OMG....
Thanks so much

The fastboot bootloader isn't the right one. So... if you hold volume up + camera shutter while powering on you end up in fastboot? That's really weird.
Maybe your keys have been remapped somehow? Does anyone know a chord to boot fastboot? Perhaps check to see if your USB port is clean?
Lmao
Just my luck to have a weird problem. I thought it may have been remapped so I have been trying the program buttonremap. It doesn't seem to let me do anything except stop the buttons I re assign doing anything :'(
Does anyone have a proper key mapping file that I can replace with my faulty one to hopefully fix it?
Or any other ideas?
Cheers everyone

Just checked my system / user / keylayout folder. How many files are supposed to be inside, there are a few. I checked the contents of some and they seemed to be the same. Just an idea.... thanks again.

Ok installed anyunlock it allows you to use any physical button to unlock the screen. It doesn't respond when the Power button is pressed, it responded fine to volume rockers, gallery and shutter though.
Anyone know if this would mean for sure its a physical problem before I crack it open and try and fix it.
Thanks guys.

Breakthrough!
I am pretty sure I have fixed the problem, I tapped the phone fairly hard on its sides and back, and lo and behold after a battery pull and replacement it didn't turn itself on, I waited, nothing, so then I held the power button and it started up!!!!
But....I have another problem that happened before that, I am stuck in the boot animation that open recovery uses before going into its program (i.e. where you can load nandroid, wipe dalvik cache etc).
I was about to load a new rom, and was in open recovery, had installed it and about to do the reset and the phone turned itself off, and thats when I got the problem with the sticking boot animation.
So just to be clear, I am stuck in a boot loop, but not with the M logo, the restore logo.
I hope the power button solution can help someone else, as random as it is.
If anyone could help me get out of this boot loop without flashing stock that would be great. ( i can get to the real bootloader now btw)
Thanks again everyone.
Solved it all
Just took the sd card out and rebooted. And the power is getting better after banging it.
Thanks to all.

So, is your conclusion is that the button was stuck and the banging freed it? It doesn't restick?
The Button is not perfect still. Sometimes over sensitive Occasionally it will not even work but it works most of the time. I am just wondering what cleaning solution I could use to free it some more.
It has certainly been a trying problem. Cheers for the help.
Now I need to figure out why I have this strange ghosting on the top of my screen.....

Samsung Galaxy S2 Power Button Not Working
Hi Guys,
Any solution for the power button problem? Current latest Android 2.3.3 Samsung Galaxy S2 also having the same power button problem. Most of the time I can't use my power button to turn on/off the screen (wake/sleep) and there's no menu for long tap as well. Luckily it does wake when i press the only physical Samsung center button.
What i have already tried: Factory Reset, disable Power Saving Mode, Spare Part+ (apps), Screen Off and Lock (apps), and all won't help.
Is there any current updates or patches to allow the power button to work as usual?
Thank you.
take it to the samsung technical centre
Thats if you still have warranty

[Completed] Problems with LG Sunrise

Hey guys, I'm having some serious issues with a stock LG Sunrise (LGL15G). My phone was working perfectly fine last night right before I went to bed, however, when I woke up this morning it started to lock up and wasn't responding so I did what any normal person would do and I went to power off and restart. Now when the phone restarted I got an error message saying "Unfortunately, the process com.android.systemui has stopped." I clicked the OK button however the message kept coming back no matter how many times I clicked it. I them proceeded to pull the battery out (the phone was not allowing me to select my power off option while holding the power button) and replace it and start up the phone. This time I got a black background and the same message and if I press it through about 20-30 times it finally disappears however, I can not do anything with the phone none of the options work except for the power option when i hold the power button. I've tried booting into safe mode and was able to work around the error (with extremely quick timing and proper clicking of the setting button and tried to do a reset however it's blacked out according to server policy. This phone is completely stock with no root/custom recovery, and I can not seem to find a way to boot into a stock recovery for this phone. I know that some of the LG phone did not come with a stock recovery installed but I have no idea how I can fix this issue. I know this isn't a support group but I've been having a close to impossible time trying to find information on the LG Sunrise since it's not a popular phone, I just need guidance to anyone who has any information on this and any possible solutions.

Hi, thanks for using XDA assist!
First, please create an account so you can post in other forums.
It sounds as if you may need to boot to recovery, and preform a factory reset.
After creating your account, you can ask for more help here:

Is this the end of the line for my N5?

I'm a serial lurker here and hate to ask for help, but want to reach out (and finally start hitting thanks).
My N5 was on MMB29S 6.0.1, SuperSU version 2.65 for root, xposed v79 (gravitybox, APM+, snapprefs), and ran perfectly fine up until a few weeks ago when I started having issues. Apps would sometimes FC, and (not always right after) system would hang and then reset. Sometimes the screen would go black but notification light still would blink.
Upon reset, it would either (a) get stuck at google screen and bootloop or (b) get stuck at some point during the boot animation. If the phone did start, it would usually work for a variable amount of time - minutes, hours, but usually not more than a day. Other times, the phone simply would not start and required a slowly increasing amount of time to boot while holding down the power button, sometimes not even booting at all. The phone would sometimes be unresponsive to holding the power button for up to 12 hours before the phone booted up again. Not saying I help the power button that long, but tried frequently over that period of time.
Over the past few days I've taken to troubleshooting in the ways I could think of and what I've read here on xda (I can link to any of the threads if you are curious) and the rest of the web. I started by disabling xposed, restoring stock boot image and removing root, and have since flashed completely to stock MMB29V and have followed the advice of @audit13 to even flash the userdata.img file and perform a factory wipe before booting the phone for the first time.
Nothing works. Even after being bone stock now there are still random resets, with the power button having to be held down for quite some time to power back on (if at all). The only difference is that it hasn't been getting stuck on the boot animation when it does power on.
I'm a bit sad, and realizing that this is probably the end of the line for my venerable Nexus 5, but any help/suggestions are welcome. Thank you in advance!
Download the Nexus Root Toolkit for your computer to try to restore your Nexus.
Could be a power button issue that's causing the resets? Have you tried removing the motherboard and quickly pressing and releasing the power button several times in a row using more pressure than normal?

I have yet to try that, but will try that in the next couple days. Might not get to it tomorrow as I have an upcoming exam.
I'm not completely sure if that's it though since the system seems to hang/freeze before powering down, but I can give it a shot. Thank you for the idea!

As a last resort I could try that -- how do you think that would solve my issue? Thank you!
Maybe a battery problem? I'm just guessing at the different things that may cause a boot problem or resets.

Pretty Sure I bricked my Sony Xperia Z3V PLEASE HELP!!!!

Help!
So literally three days ago my dad gave me his old phone. It was a rooted Sony Xperia Z3V. I realized that I could not play Pokemon Go and so I installed the files a YouTube video told me to install to get Magisk, a program like root cloaker that should have let me turn on root toggle so that I could play Pokemon Go. I soon realized that this was not the case or I seriously messed up. Now my phone will not turn on. When I hold the power button it just vibrates and does nothing. When I hold the Power button and both volume buttons it shows a Sony logo after a while and then turns to a screen that says System Recovery at the top and has four options: Continue Power up, Safe mode, Factory Reset, and Power down. Absolutely all of them just turn off the phone. The Factory Reset has four options when you select it. At the top it says "Continue with Factory Reset?" and it has the following options: No, No, No, and Yes. All of those do nothing as well other that turn the phone off. My dad said he might have a backup on his SD card that he might be able to restore it to. However, I'm not sure he has this so if you can help please include a way without that. Also, my Dad told me that Sony Companion does not work with this phone. Please help. I know it was stupid but I'm still pretty new to rooting and I'm still in 8th grade. Now I'm back to my Droid Ultra. I know it's kinda a third world problem to have a slightly worse phone but I still broke the phone that my Dad gave me. It would mean so much to me if someone could help me I'm desperate.
Thanks,

Greetings and welcome to xda. First off don't worry your phone can be fixed easily, there are plenty of threads and tutorials on xda on how to hide root for certain apps. If root isn't important to you then just reinstall a stock rom.
