How do I backup/restore stock recovery? - Samsung Galaxy S7 Questions and Answers

Hello, I have a Exynos S7 running on Nougat, and I'm getting ready to install TWRP. However I'm trying to find a way to make encryption work on a rooted device, so I need to restore the original recovery image after I root and everything. Where can I find the .img? I read somewhere that TWRP will make a backup of it, but I haven't been able to find it anywhere. I've also looked online and I haven't found any backups.
I got it to work a very long time ago on a previous S7 running Marshmallow, but that's been a long time and I don't remember how I did it, I just remember that I used CF AutoRoot for the rooting process.
I know I won't be able to use systemless root, but theres nothing I can do about that.
Thanks

[Q] Rooting the Charge

Alright, so I've been reading the forums and trying to keep up with everything going on with Charge development...but I'm still lost. I want to root my phone, as my old fascinate was rooted and I really liked having titanium backup, but never could get CWM to work on it. I don't know why, I followed the directions but only soft-bricked it a couple of times, so I gave up.
With the Charge, from what I understand, I can use Odin to go back to ED1 and then root from there. OR I can use Odin to flash a custom rom that will root ED2 and add CWM recovery...I think.
One thing I've seen is that I need to create my own backup in Odin before I attempt any of this, but to do it I need to be rooted so I'm not sure how to handle that situation either.
I've read the forums and I've done my research, but I still feel like I'm missing *something* as to how I can root the phone, what my problem with CWM was, and more importantly- how to create a backup? For instance, I keep seeing things about nandroid, but can't find anywhere to create a nandroid backup or any information other than people saying to use nandroid.
Any help is greatly appreciated!
Nandroid only comes from CWM AFAIK. what I did was just install JT's root/CWM/voodoo via ODIN and then did a backup that way. then no matter what I did I could at least get back to that and then restore to a ED1 downgrade if I had too. You are right, other than using Back Up Pro, you cannot do an Odin backup without being rooted.
Good Luck

I'd also like to Root mine for the use of Titanium and some other root only apps but I don't want custom, buggy ROM's or getting stuck with a downgraded devce that can't be upgraded....or worse, bricked from the hack.
Hopefully before long there will be a one click root for stock ED2 rom users.
.
Thanks! I'll give it a shot tonight and see how it goes!

Root issue

Just got the phone and tried rooting, but that happened, but also on twrp I noticed that it's saying "stock restore failed, attempting ramdisk restore, ramdisk restore failed" then aborts, so if anybody could help me it would be much appriciated. Oh yeah my model is G930FD
Update: Even other rooting methods fail such as kingo for example, so I'm not sure what's wrong
Just noticed u mentioned it. Sorry.
I have an ASUS ZenFone 2 laser ZE551KL & having hard time rooting any suggestions?
Did you root it with chainfire autoroot method with odin?

I tried but it doesn't work. I don't even know what to do to try and get it to work. I've tried formatting my data and factory reset, but it's a no go. This is my log btw when I try to flash superuser
Few days ago, I have suddenly lost root without any reason. I didn't update the firmware or anything. So, after searching what the cuz, I read somewhere that samsung pushed security update which somehow made people lost root (still don't know how!). Anyway, what I did after many tries of rooting again, is that i found there is an update for the firmware and I downloaded it and install it and root, the everything come back normal.
If u have the last firmware update then I would recommend to flash stock firmware and do all the work again (twrp+dm.varity+root)

(Newbie) D6603 root

Hi.
I have recently bought a secondhand d6603 on Android 6.0.1, build number 23.5.A.1.291
I need to find a way of rooting my phone (easiest way)
I have rooted phones before but only by using Kingroot etc
I have been going round in circles looking at websites explaining it but don't understand some of it.
All I want is an easy explanation of how to do it that I can follow.
Can I root without unlocking Bootloader? If not, how do I do it?
I really need someones help if possible. Like I say, the easiest way possible would be great.
Thanks in advance. Love the group
You can keep locked bootloader as long as you use ROMs with stock kernel. They will specify this and most here are for LB.
http://forum.xda-developers.com/z3/general/recovery-root-mm-575-291-lb-t3435214
This will get you recovery the fastest way and from there you can flash a pre-rooted .zip or custom ROM
Many thanks for that, however, I managed to remove the Bootloader and install TWRP. First thing I did was do a backup using TWRP but now I am stuck in a bootloop and don't know what to do :crying:
I reinstalled the backup just incase it was something like that, but even after reinstalling the backup, I'm still in bootloop.

Please help

Guys, my son messed up and followed instructions off the Max "HighOnAndroid" at www.galaxynote5root.com
He flashed twrp 3.0.2-1
He followed step by step. After flashing twrp, he booted back into recovery and flashed
No-verify-opt-encrypt
And
Update-SuperSU-v2.46
When he booted it back up, its stuck on the sprint splash screen. It is specifically in the screen that says LTE Plus More spectrum better network.
After I got off from work, I came home to him crying.
Ok, I have started to download the factory ROM from Sammobile but I am wondering if maybe there isnt an easier fix. I am not to familiar with changing kernels. Ive never needed to worry about them. Could I maybe just need to flash a new kernel?
From looking on here, really all he needed to do was flash twrp then SuperSU... Does anyone know a way to fix this faster than waiting 6 hours for the Sammobile stock rom?
Please help
Edit....
Ok guys...
I got the file downloaded from sammobile. I installed it and got it installed and working. Then I tried to do the root myself. I followed the guide on this site. However I still couldn't get it working. It was still bootlooping. But not the same bootloop. This time around, it didn't get past the very 1st screen. I again flashed back the stock ROM and again everything works fine.
The files I tried to install are:
Twrp-3.0.2-1nobleltespr.tar.md5
Then I did the twrp install boot deal, booted into twrp and installed:
BeastMode-Stock-N920P-1.3-O16.tar.md5
BETA-Flashable_SuperSU-2.52
I now take it that the issue is my twrp says noble while I read not to use the noble kernel to use BeastMode. But I could be way off...
Man alive, I didn't know just how much I appreciated CF Auto Root until just now...
You probably already figured this out by now but follow the instructions and links in my thread. You should only reboot directly to twrp from download mode after flashing twrp btw in case you haven't figured it out by now.
The method you are using is from a very old thread. Follow the instructions in the thread below.

Thank you for responding. I was able to get the factory ROM installed and working fine.
I have downloaded the MOAR for the device and plan on giving it a go.
I still haven't been able to root the phone. EVERYTHING I tried resulted in bootloop. So I just decided to stick to stock on his phone until I can actually get it figured out...
As far as the SuperSu being old, I got it directly from the website of the maker. https://download.chainfire.eu/696/supersu/
I REALLY want to get this phone rooted for him, as I am certain he is going to keep trying following random YouTube videos regardless of my instruction.
Like I said in my last post, I have never missed cf auto root so badly...

Root on stock is relatively simple.
TWRP + SuperSU only.
But as you saw, it's still easy to get it wrong.

Ok, so since I have flashed TWRP and SuperSU, and all it ever does it bootloop, would I be able to install TWRP, then flash MOAR on top of it? Then I would have a rooted MOAR if I understand correctly. My issue is that ive always had root accomplished before installing a custom ROM.
If all I have to do is flash twrp then SuperSU, I dont understand what I could be doing wrong.
But I'm going to take a look at your link you provided and see if I can't get root 1st.

Old habits are hard to break. A properly deodexed rom that is pre-rooted only requires twrp and a proper wipe before installing.
For rooting stock, it really is fairly simple. The instructions I provided are probably a little overly detailed but I had to cover as much as possible for those that have never done it before so it 'looks' complex but once you've done it a few times you will see that its really not that hard to do.

Thank you for pointing me to your thread. I was able to get root on my sons phone. Hard to believe the SuperSU was the problem... But it was... I was using the one from chainfires site, but yours worked when his created bootloops.
Thanks again!
Is there a root method for pk1

How to dump/backup my own stock firmware without root (nandroid like?)

Hi Team,
Prior any play with my new G930FD I want to fully backup all firmware elements like radio, EFS, etc. to bring it back to state as it is now.
Once this is done I can play with adding root, etc.
Thought process was that it should be possible with ODIN, but I can't find a guide treating this subject.
In the past I've used to use Philz Touch on S4 LTE and all worked fine besides I've had troubles to restore NAND backups. Needed to move back from LineageOS to older CyanogenMOD (due to some issues) only to find out that old backup was not working anymore. I've tested backup earlier but it was years ago and didn't re-test procedure anymore.
Since don't want to run into any similar situation that can't revert to state as I'm in now, thought will asks you experts here.
In the past I'd think about process of booting recovery from computer via fastboot, performing required backup to SD card and them doing whatever I'd need to do.
Checking all guides (and believe me I've spent plenty of time trying to find it) all I was finding was that it required root to perform dump, i.e. using su with dd.
I've no issue to type in terminal as used to patch kernel back in times of kernel v2.4.
I just want to make sure that throughout the process of getting root, I'll have always a roll-back procedure and don't want to trip Knox and other flags, whilst if possible keeping OTA access (based on guides here, this should be possible).
Please advise on steps I should take to backup all current data with any tool or point me to place I've missed as I'm sure someone has described it already and I'm just being blind.
Thanks in advance!

There's a method to do that but I'm afraid it's not for our phone, because you see for the devices that can install twrp with fastboot command you can make a command that only boots twrp "fastboot boot recovery" or something like that, I don't remember clearly,instead of "fastboot flash xxxx" but we can't flash twrp with fastboot so that's impossible for us I think, I strongly advise you not to try these methods because you might end up bricking your device, if you are afraid you might mess up your phone stay away from the root and flashing, AFAIK there's no other method than the one with Odin and formatting data.
Thanks for answer, hoped I was just missing something.
Might be interesting for some people, and in fact for myself too.
I've found out that baseband version I've is not listed at Sammobile:
https://www.sammobile.com/firmwares/galaxy-s7/SM-G930FD/
It is:
G930FXXU1DQEJ
Not sure how to proceed should I run into issues?
I do also consider downgrading back to Marshmallow to take advantage of Xposed.
btw. it was all so easy, nice and sweet back in times of my S4 LTE play and now it is all so complicated, that even encryption with root seems to be so, so dangerous. :-S

Maybe this one https://forum.xda-developers.com/android/software-hacking/tool-twrp-backup-restore-tool-pc-t3572241 or https://forum.xda-developers.com/galaxy-nexus/general/guide-phone-backup-unlock-root-t1420351
Long time ago... though forgot to make sure I say thank you! I've had laptop OS level issues and missed to say that. Sorry.
