Need suggestions for this.
A few weeks ago I rooted my phone to remove some apps that I never used. I just kept using my phone as always and did nothing special except removing those apps. Today I decided to unroot my phone because I felt it would be safer in case anything should happen to it (HOW IRONIC). It's only 3 months old and I didn't want to loose my warranty. I opened the SuperUser app and clicked full unroot and clicked continue. My phone instantly returned to the home screen and then powered off. Then it turned on again, but now the message "Samsung Galaxy S7 powered by Android" keeps flashing on the screen. I went into recovery mode and tried wiping the cache first, but nothing changed. Then I wiped all my data and did a factory reset, but my phone keeps flashing and won't turn on. I'm really desperate and don't know what to do because I'm afraid I can't take it to my retailer because my phone is rooted (if it still is rooted, but I have no idea). What should I do?

Hello everyone,
I searched the forums for awhile but could not find a satifying answer for my question. So i am hoping you guys will have an answer for me.
First of all i would like to point out that i am not looking for an answer for how to unbrick the phone. There are several guides and hopefully when i get home i will be able to fix the problem. *Fingers crossed*
I did not have my Galaxy S for long. After getting it and installing KIES and updating my firmware the battery life what terrible so I rooted the phone and then installed Gingerbread 2.3.6 JVU. it worked like a charm.
Yesterday when I was playing with the CWM application, I decided that i was going to back up the phone and backed it up using the application. This morning one of my programs was acting weird and I decided to restore the backup I have done yesterday.
Upon going into applications and CWM, I chose the restore option and started the process. Everything was going smoothly, the phone was plugged in to the charger as well.
When the phone rebooted after the initial process I am stuck at logo screen. i can go into download mode (That is why I am hoping that I will be able to unbrick it) however that is as far as the phone goes. When I try to go into CWM Recovery mode, I am once again welcomed by the phone getting stuck at logo screen.
Does anyone have any idea as to why this might have happened? To avoid future problems is there any extra steps I should have taken before using the CWM restore function?
Thanks for the help.

Maybe your backup was corrupted somehow. You could have tried wiping the dalvik cache after restoring your backup (before rebooting), but its too late now. Since you can get into download mode, you can easily fix the problem (your device is just soft bricked - nothing to worry too much about).

The phone rebooted automatically. Did not give me the chance to do anything beforehand.
As you said the phone was soft bricked so when i got home that day i just fixed it. No problem. However I am really really into getting to find out how a 1 day old back up can get corrupted.
Galaxy S4 Sprint Encryption failed - stuck on Reset Device
Hello all,
First, forgive me if the steps I followed below don't make any sense, I don't really know much if what I am / was doing. Anyway:
I have a Galaxy S4 from sprint, L720
I'm about to sell my phone, and I few months ago I rooted it following this procedure using odin:
http://forum.xda-developers.com/galaxy-s4-sprint/general/rom-100-stock-l720vod2-5-0-1-t3105760
Not too much to say here, this is just more of a background information.
Anyway, Because I'm selling my phone, I wanted to make sure my information was deleted securely form the device, and found that many people said it should be encrypted.
I tried to do that, and after a couple of hours of the phone stuck on a blank screen, I removed the battery and restarted it.
Now I have a screen that says "Encryption failed" - "Reset Device", only the button to reset it, does nothing.
I follow that guide again, installed that rom again.
I also have twrp, did factory reset, wiped all the data, and still, when I boot, I get that same message.
I have also tried to backup the data (after the debacle), restore it and factory reset the phone.
This leaves the phone stuck on the very first screen, "Samsung Galaxy S4", which maybe a good sign or not.
Any ideas?

Reflash your device with stock firmware and wipe it.

That worked. I had tried with other ROMs, such as the rooted one mentioned above and it did not work. The original one did. Thank you sir!
Hi, I'm in a bit of a rage right now. Need my phone for work, and also afraid of loosing all the pictures and videos I've taken
So my phone has worked perfectly for months, updated several times, but today after the last update it's stuck on the boot logo, the Samsung one.
I've tried hard reset with Power+Down, it just reboots to the same logo and stays there forever. I also can't get into recovery mode with Power+Up+Home, it just gives me a yellow triangle with an exclamation mark in it for 1 second then boots back to the samsung logo. Tried Kies 3, it doesn't recognice the phone at all, tried everything in there.
The only thing I can access is the Download mode Down+Power+Home, I have no idea what to do there, I've read about Odin but that looks like some NASA-stuff way above my knowledge, isn't there just a way to get it back to previous version? Orginal, stock and all that? Don't wanna mess with roots if that can be done
I'm out of ideas, please help me, are all my data gone? Pictures, video etc? :'(
Help please
*Sorry for bad English, not my native, but I hope it got trough.
Sounds like an update gone wrong. Restoring the phone isn't so hard but saving your pictures and data is harder in most cases. You can try using Smart Switch and see if your device shows up on failed updates, maybie it can repair the installation. You can also use Smart Switch to restore the phone completely, but this DELETES everything on it. If you haven't rooted phone and have warranty, I'd return it to Samsung with strict instructions that phone broke when software update and that you want to keep your data/pictures. If the phone is rooted there are ways to extract data from the phone memory but I'd only do that as a last option.

Yeah, I did the upgrade with modelname and S/N trough Smart Switch, it worked, but all data was lost including all my contact phone numbers, hade over 350 :| don't think they are synced either? :|
Anyway, glad the phone works, will never install these stupid updates again, never noticed a single improvment after them anyways

Hi mate
I would reflash again with odin using home csc instead of CSC so you do not loose your data and settings......
Edit : once it has been rooted the knox bit is set , there is no way back
Hello....
After factory reset, my tab wont turn on....
Please help
Did you charged long enough? Is it stone dead with no signs of life or bootloop(Samsung logo loop)? Does it receive messages?
I am affraid not enoug charge or batteray....
This is the massage
I did the factory reset...
No respon even i press power+volume up/down
Now black screen...
Had you rooted or installed custom rom/recovery before that?
No.....
So you did not tampered with the device, all official software, one day wanna factory reset, the battery went dead midway, and the tab died? Purely asking.
(Your warranty is probably expired as you are asking here.)
I know this is an old thread but i was just reading now, and perhaps it's helpful to anyone else in the future. I'm not sure what the problem here, but when i froze a service in titanium, i had the same exactly message although tablet was booting to os. You couldn't even bypass locksceen. What i did was boot in twrp and flash a file (i have posted in other thread) to unfreeze all apps. After this it booted.
So there is a service which creates this message and a problem. But if you are unrooted by reinstalling rom in odin it might work..
