Want to unroot, need help please - Samsung Galaxy S7 Edge Questions and Answers

Hi,
I'm new to android and recently rooted my Galaxy S7 Edge AT&T Snapdragon and now I want to unroot and return to stock but I'm having trouble.
To begin, I can't access recovery mode anymore. I get a message in the top left corner of the screen that says something about "custom rom blocked". I tried to follow instructions I found on XDA on how to unroot and return to stock. I downloaded the files and used Odin to flash it, it begins to do something and then gives me an error.
What am I doing wrong or how do I fix it? I apologize if I'm not explaining this the greatest, like I said I'm new to this and don't understand it much. All I want to do is wipe the root and return to stock. All help is greatly appreciated!

If Your phone works then try this ^
If Your phone is dead then post the log from Odin.

Thanks for the help! I tried it multiple times and it says each time "uninstallation failed". Could it be the issue I'm having with the recovery image?

I don't think so, but I guess that the best thing You can do right now is to just reflash the whole phone with Odin, but since You get errors in Odin I need to see the log.

I successfully unrooted last night using these instructions and the files provided. I don't know if it'll work for you though.
Instructions: https://stockromupdate.com/how-to-flash-stock-rom-samsung-smartphone/
Files: https://stockromupdate.com/2016/08/...galaxy-s7-edge-sm-g935fd-6-0-1-g935fxxu1apgf/
Note: Make sure you ignore the Home_CSC file AND the Pit tab in Odin. Never touch "Pit" unless you know what you're doing. And also note that the ROM provided might not be the one developed for your country, but it should work fine.

How can I tell if my N1 is rooted?

I just swapped my HD2 with someone for a N1, and I'm trying to figure out if the phone is rooted or not... I've never had an android phone.
When it boots, the little "unlocked" icon appears at the bottom of the screen, and it appears to have the "custom recovery screen" when I enter the recovery section of the bootloader I get this image:

I ask because the phone shows Kernel version 2.6.29-gad36b87 and build number ERD79, and I wanted to put froyo on the phone but was told only to update froyo from ERE27. I tried to flash ERE27 from the sd card using the recovery screen but keep getting an "unsigned files" error.
I suspect that this is a custom rom already, but have no idea how to tell if it's rooted etc.
Any help is appreciated. Thanks.
Yes it is.
Seems like you have a stock ROM, but custom recovery. You'll need stock recovery to flash the ERE27 update.zip
or you can just flash non stock update like the one of Paul's
the tut thread is here in this forum
Will the Wipe option in that recovery screen accomplish that? I don't mind trying one of the non stocks, but I'm 100% new to this and would love to avoid destroying my phone
Depends how you want to do it.
If you want everything stock, then the easist thing to do would be to grab the complete ERD79 image, flash that and you're good to go, it should OTA to ERE27 pretty quickly.
If not, then as above you can look at a non-stock update, there are tutorials for both, so just take your pick.
Thanks for the advice, I will try one of the non-stocks, I just wanted to make sure that I'd end up with root access and not get hung up halfway through the install.
just go with this one:
http://forum.xda-developers.com/showthread.php?t=686734
its the best, i did it today myself as well

I was on the P1000DXJK2 at first. I'm trying to flash P1000DXJM4. At first it was successful from the odin 1.7 but when boot up it stayed at the samsung screen. Maybe i need to flash the dbdata.

Hi,
Same thing happened to me. There are 3 problems;
First is that you do not have enouch battery power to run RDS.
Second is that you have to load SBF file again with RDSLite.
Third is that you have to unlock your bootloader not to have the same situation.
But to make you feel happy, I can say that your phone is not bricked.
We shall go step by step for your problems. First of all, do you have second battery or can you supply it because it is necessary to overcome second and third problem ?

Hi,
Please use search.
Thanks,
I'm having the same problem "failed to boot 2". Minus the battery part.
I did all the following steps a few months ago to update to the new gingerbread firmware from http://forum.xda-developers.com/showthread.php?t=1182871
Claims I would have an unlocked bootloader, root, and CWM. Which, I have root, CWM, and evidently still on a locked bootloader per a post I read on androidforums.
I'm lost as I've been reading so much that I've done confused myself on what I should actually do, and feel worse off than I was before I started reading.
Overall, my phone works fine. I just wanted to flash a different ROM. I'm just not sure where to start to fix my problem (redo all the steps in the post I linked up, or flash a whole other SBF file). Any help would be greatly appreciated. Thanks!

[Q] Water Damage - Won't Boot

Hi all! Walked into the lake with my phone in the rear pocket - doh! Here is what I did so far ...
1. Turned off
2. Removed battery
3. Disassembled phone
4. Dried it out
5. Cleaned all the components with isopropyl
6. Put in a new battery
Turns on fine
Goes into d/l mode
I can flash firmware to it via Odin
Will NOT boot
Will NOTgo into recovery
I have tried various stock firmwares from Samobile - they all do the same thing - see pictures below.

ANY firmware I try does this after Odin is "Successful" Blue writing says " Recovery Booting ... but it just sits there.
Any ideas? It is a stock Rogers phone but I don't mind using any Firmware ion any network if I can get it up and running - I'll just unlock it later.
Thanks!
Also, can I try to re-partition it using a .pit file? I've only ever used Odin for flashing firmware. Where can I get .pit files, can't seem to find them anywhere.

Bricked GT I-9505

I have been using one of the Lineage 14,1 versions of android lately and today I wanted to return to stock Lolipop using Odin. Unfortunately about half way through I got write error so I tried again and got another write error probably at the same time. Now the flashing doesn't want to even start and I get various error messages in Odin. The latest one is "There is no PIT partition. "
Obviously I cannot boot now I can only enter download mode.
Any ideas?

After numerous attempts, various cables, different usb ports I cleaned usb ports on my original cable and it was a full success.:good:
Glad you got it working.
I recommend using Odin 3.07 and higher in future.

Well I tried 5-6 different versions of Odin before I settled with 3, 1,85.
