[Q] How to unroot an A3 2016 (SM-A310F) ? - Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot

Hi everyone,
I rooted my A3 2016 SM-A310F on Android 7 Nougat by follwing these instructions (basically it's with the CF-Auto-Root way). But I got this lag when I unlock the lockscreen. Looks like I should have used Magisk instead.
So, in order to install Magisk, I need to unroot my A3 first. I guess I could reflash some stock ROM (as explained here), but I'd much rather use a lighter way so that I woudln't have to wipe my data / downloaded apps / parameters. Is that possible ? How ?

Well, I found the solution myself and I'm posting it for whoever has the same question in the future :
got to the device page on firmware.mobi
download the boot image in .tar format
reboot the A3 in download mode (boot while pressing volume down + home + start)
flash the boot image you downloaded
reboot
You're done, and no data got lost.

My experience with "Custom Binary Blocked By FRP / FAP Lock"

So everything was working well with my S7 (Helios 7 Rom), but I wanted to try the S8 AOD apk.
After flashing the zip some wierd graphical glitches started appearing on my phone, so I tried to fix them by disabling done options.
Well the issue is, I didn't know that If you disabled​ developer options (or the OEM unlock option specifically) then your phone won't boot as long as you have a custom recovery.
The error you'll get is: "Custom binary vlocked by FRP lock"
(top left corner in red when you're on the samsung text while booting)
The only thing you're​ able to boot into is download mode.
(btw and to quit download mode you'll have to hold vol down home power)
Many people were saying that wiping is the only way to fix this, but i can't wipe as I have important data on the internal storage.
But luckily I was using a stock rom, so I downloaded​ a recent S7 nougat firmware from the general forum here and flashed it with Odin, and what do you know! I was able to boot normally and my internal storage files are all there.
Now to go back to TWRP and custom roms, I have to wipe my internal storage but at least I can backup everything and flash cfroot to get root then backup all my apps with titanium backup (to external storage).
After that just follow this thread:
[ROOT] (Updated) Official Stock Nougat 7.0 (100% Working) - All Exynos Models
https://forum.xda-developers.com/galaxy-s7/how-to/root-official-stock-nougat-7-0-100-t3540765
then you'll be back to twrp and can flash custom roms. (but that procedure will wipe your internal storage.
good luck to everyone, just wanted to share this in case anyone faced the same situation as me.

Trouble with booting after rooting, help.

Hello everyone, I went to root my phone today, I used a Youtube tutorial with the exact links/downloads given. Followed the steps but my device is having trouble rebooting, it is just stuck on the Samsung logo flashing and I'm not too sure what to do. Also when it boots up I get the error message in the top left of my screen saying "Recovery Is Not Seandroid Enforcing", hopefully that helps.
Thanks.

You need to flash SuperSU manually.
1. Flash TWRP
2. Format data
3. Flash SR3-SuperSU-v2.79-SR3-20170114223742.zip
http://download.chainfire.eu/1021/SuperSU/SR3-SuperSU-v2.79-SR3-20170114223742.zip
You simply brick your phone. You need to know that there is not Chainfire-AUTO-Root for Nougat, so you need first flash Stock FIRMWARE from Sammobile, then flash TWRP and flash SuperSU
Or you can flash many of 100 roms with prerooted supersu and busybox.
Hi there,
After upgrading my S7 Edge G935F to stock version xxu1dqd7 (with latest May 2017 upgrades) I had to install TWRP (twrp-3.1.1-0-hero2lte.img) again.
Unfortunately this change will NOT recognise my pattern lock now! I had to re-install the stock image (DBT-G935FXXU1DQEF-20170523093738 with ODIN) using the HOME_CSC file to hold my data.
This re-installation brought me back to the game, but without TWRP and hope for root, but the pattern pin (the same) is now working...
Update 1
Installing TWRP (twrp-3.1.1-0-hero2lte.img) over the new stock image (DBT-G935FXXU1DQEF-20170523093738 with ODIN) without having the pattern lock enabled feature during start will result in stuck on
the samsung title.
Update 2
I had to repeat the step above (stock firmware), so stay now without root.
Will check later with other stock versions
>It seems you didn't format the data partition or dm-verity was not installed. Happened to me, won't boot if >anything is altered like when installing a custom recovery.
Yes, I did it with and without dm-verity, All 3 options,
TWRP (ok, but pattern lock will not recognized)
TWRP + supersu (2.82) (stuck on the samsung logo)
TWRP + supersu (2.82) + dm-verity (stuck on the samsung logo)
Yes, I didn'T format the data partition. Didn't want to lose my data ( Never had a problem to upgrade stock roms on my old S4 and root after).
Before the stock upgrade, I run with the Jan 2017 patch level (I bought this 2 days ago) and was able to root with the above method.
Today I wanted to jump the the latest stock version but run in trouble then.
Update 3
Downgrading to Stockrom from 2017-Jan-30 Germany 7 G935FXXU1DQB3 G935FDBT1DQA8 is not an option (anymore), The system boot up but with lot of errors and it's unresponsable and not usable.
Upgade then to the April patch status (2017-Apr-17 Germany 7 G935FXXU1DQD7 G935FDBT1DQD1) brought me back to operational,
but TWRP + supersu (2.82) + dm-verity (stuck on the samsung logo).
Will try it now with the Februar patch version
Downgrade to the Feb patch status (2017-Feb-23 Germany 7 G935FXXU1DQBX G935FOXJ1DQB2) had the same resut like the Jan version - not usable.
I'll give up now and install the April version without TWRP.
I need root to restore my apps AND data with Titanium Pro.

With the TWRP + supersu root method, no matter what 7.0 stock ROM you use, you will not succeed before you disable boot pin and format data. You can restore data after rooting.
So start with the latest stock ROM that is working 100% for you, flash twrp, format data, flash supersu, and it should work. You have to format data because root and stock rom currently does not work with encryption.
Or even simpler, use the new cf autoroot, however it seems you still have to format data.
I had high hopes that the new cf autoroot nougat binary would work with encryption, but alas it seems it doesnt, at least I had the same wrong pin code at boot issue as with twrp. I havent had time to test it, nor to format data and root, so I am currently not rooted.

Thank you doclorenzo.
I had success with the latest stock version (xxu1dqd7) and your recomendation to format data in TWRP.
In short: Boot in Download mode, Install TWRP via Odin, Boot into TWRP - format data, supersu (2.82) + dm-verity
and then restore all data. Unfortunately it requires lot of time (at least 4 hrs to restore the apps + more for fine tuning)
Thank you and hope to have a better way with the next stock update and TWRP

Galaxy J7 2016 (SM-J700T/T1) How to Root and Install Xposed

MM/N - How to Root Samsung Galaxy J7 (2016), Install TWRP, and Install Xposed. (SM-J700T/T1)​
Disclaimer​
Your warranty is now void.
I am not responsible for any bricked devices. This is the way I did it, some steps may not be necessary.
I'm just sharing what worked for me.​
Preparation for ROOTING J7 (2016) :
● Enable USB Debugging on your J7 (2016)*
This is very important thing to be done before you try flashing a firmware or recovery file. USB Debugging mode make Android devices receptive to download and send data over USB cable connection. If you do not know how to turn debugging mode ON, do this :
● In your ROM, go to Settings -] About device. Tap 7 times on Build number to enable Developer options.*
You will see a message that “Developer mode has been enabled” on your device.
● Now go to Settings -] Developer options : Tap it and go to USB debugging option and check the box to enable it.
● In the ‘Developer Option’ you will also find the ‘OEM Unlocking’ option, just enable it. (You need to enable OEM unlock, Otherwise you might end up with boot problems or be unable to flash later on)*
● Install Samsung Android USB Driver for Windows to your Laptop/PC, Then connect your Samsung Galaxy J7 (2016) with USB cable. It will configure driver automatically.
How to ROOT Samsung Galaxy J7 (2016) :
1.] Download Odin, TWRP Recovery, Custom Kernel & Magisk files to your Laptop/PC.
2.] Turn off your phone, Go to download mode (by pressing Volume down+Home+Power buttons at the same time for about 6-8 seconds).*
3.] Press the Volume up button to continue.
4.] Open the ODIN file and run you downloaded on your Laptop/PC.
5.] Connect your phone to your Laptop/PC through orignal USB cable.
6.] When ODIN detects your phone, It will show added in the Log.*
7.] In ODIN click on AP and then select the twrp recovery file by ashyx(twrp_3.0.3-1_sm-j700t_23217.tar). under Options tab disable Auto Reboot. Click on start, The flashing process will start. Once the flash is complete, exit Odin and disconnect your J7 from USB cable. Press Volume down+Home+Power buttons at the same time until the phone turns off, then immediately switch Volume Down to Volume Up, while still holding down the other keys.
You should now see the TWRP logo on your screen. Swipe to Allow Modifications.
8.]*Mount Internal Storage in TWRP:*
Go to download mode again and Open ODIN click on AP and the select Stock based custom kernel (SM-J710F-Kernel-6.0.1-nodmv.tar) under Options tab disable Auto Reboot. Click on start, The flashing process will start. Once the flash is complete, Now exit Odin and disconnect your J7 from USB cable, you can pull the battery then place the battery back in again.*
Note 1 As per my experiences, it is recommended to flash the Kernel, then recovery and then "FORMAT DATA" (not only wipe) to disable encryption. Otherwise, TWRP will not be able to mount /data.*Now, use the back button until you're at the menu. Reboot -> Recovery. Now flash ashyx's boot image patch (no-verity-no-encrypt_ashyx) to keep the system from re-encrypting.
12.] Use the back button until you're at the menu. Reboot -> Recovery. Copy and place topjohnwu's Magisk Stable or Magisk Beta zip file to your Internal OR External SD card.
14.] The recovery will start. Select 'install zip'.
15.] Go to and select the Magisk zip which you downloaded. Swipe to Confirm Flash. Flashing process will start. Now flash ashyx's boot image patch (no-verity-no-encrypt_ashyx) to keep the system from re-encrypting.
16.] Reboot -> System.
ENJOY your rooted Samsung Galaxy J7 (2016) !!
Install Xposed Framework on J7 (2016) :
Most Android users mainly root their devices only to install Xposed Framework. Xposed Framework is a powerful tool that enables you to modify your ROM as you wish using some tweaks. Xposed Framework can be installed not only on Custom ROMS but also on the Stock ROMS. So using Xposed you can add some tweaks to your Stock ROM or firmware and get the features of a custom ROM.
Preparation for Install Xposed :
Make a nandroid backup using TWRP (in case if anything goes wrong) before installing Xposed Framework.
With the Nandroid backup (which is an excellent feature on custom recoveries like TWRP) you can backup all your current state of your operating system on your device and save it in your SD card or on your Computer storage and restore it at anytime you want. Many people will have perplexity that, If their Stock ROM (Firmware/OS) is rooted would it be able to do a backup of their OS and can able to restore it?. Yes you can do backup of the current state of your firmware with the custom recoveries like TWRP no matter your OS is rooted and made changes by using root.
Steps to install the Xposed Framework for Galaxy J7 (2016) :
1. Open up Magisk Manager.
2. Go to Downloads tab.
3. Search 'Xposed' without the quotes.
4. If you are on Nougat, select the version for SDK 25. If you are on Marshmallow, select the version for SDK 23.
5. Select Install.
6. Reboot.
Enjoy the Xposed framework on your Samsung Galaxy J7 (2016) !!
How to use Xposed Installer :
1. Go to Xposed installer app on your phone and select Download.
2. Download and install the different modules you want to tweak your phone. After downloading a modules please don't open the app until you enable it on Xposed framework by going to Module section on xposed installer app and selecting it on the check box there. Then restart your phone to use the module you have installed.

Your guide will be helpful to those still on MM, but why do you have a part in your instructions about flashing a kernel for the J710 (which is the j7 2016, for the j700t which is the 2015) and a totally different phone. If users flash that kernel they WILL bootloop their phones. And the vyper kernel is a nougat kernel and will not work with a MM rom. At all. Fyi, if anyone flashes any kernel, root must be flashed after and the encryption breaker. Each kernel every time. Not being a **** just noticed some issues and figured I'd help clarify

You're right, it was a bit confusing, I'll just take out the part about the kernel.
Wait so have you tested the Magisk Xposed for nougat? I think it's in beta and I am quite terrified of trying it...
Topjohnwu says the behavior should be identical to the original zips. Official xposed for nougat was released a while ago with 'some fixes to Samsung roms' , and some people said they got it to work by deodexing their rom. To avoid that step, we use the magisk xposed. If you are willing to deodex your rom, then you can try the official xposed.

Someone here to see if he has the same problem, it turns out that when I try to rotate the screen, like watching a video on YouTube, the phone restarts only a little research and it turns out that the error is caused by Xposed no matter if it's the official version or the magisk version causes the same error, I'm in stock J700T nougat obviously someone is passing this error

S8 Exynos root question

Hi, I wanted to finally root my phone so I followed the Magisk guide but it's prereq. is to install TWRP first and apparently the official S8 firmware which my phone has (Android 9)
triggers 'auto recovery restore system' every time the phone resets effectively making it imposible to enter TWRP mode 'cos it replaces it with stock recovery mode
So the TWRP guide says I can fix this by deleting a certain system file which, you guessed right, requires root...so I'm stuck in a loop
Any ideas how to deal with one or the other? Is using an older root method like SuperSU the only way since flashing an older or custom OS requires TWRP again
Just wanna root my S8 G950F

Sounds like you haven't install twrp correctly.
What guide are you using and how have you actually tried to install twrp.
If using magisk there are two ways of installing, one with twrp one without twrp.
