DO THIS AT YOUR OWN RISK!!!!!
I AM NOT RESPONSIBLE FOR ANY ERROR OCCURS DURING THIS!!!!
PLEASE FOLLOW THE GUIDE STEP BY STEP TO DON'T FACE ANY DAMAGES/ERRORS.
First of all, You must confirm that your device model is J200G.
Otherwise it may damage your device!!!
I am not responsible for that.
That is, this guide is for J200G only.
Next, Check your firware model.
The model of your firmware must be : J200GDDU1APB1/J200G1APB2
Because the latest firmwares does not have any propper guides to root.
If it is yes ,then follow my commands otherwise you must downgrade your firmare by downloading firmware : J200GDDU1APB1 and flshing with odin tool(Downgrading the firmware doesn't change any type of settings in device).
Step 1 : Download the latest version of TWRP recovery .tar file for Galaxy J2 from the link.
Step 2 : You must unlock your bootloader.To do this , go to "Settings/About device" and tap "build number" 7 to 8 times . (It says "you are now a developer") and go back .And then, you see an extra option named as "Deveoper options" in settings, click on it and turn on "OEM Unlock" . This will unlock your bootloader (Unlocking bootloader will void your warrenty).
Step 3 : Switch off your mobile and boot into odin mode. To do this, switch off your device and press and hold the volume down+power+home buttons at same time. The device then displays the odin mode (Note that the FRP Lock is off otherwise it will lock custom binary).
Step 4 : Download and install the "samsung drivers" from link, and download and install the latest version of "odin" from the link on your computer and open it. And then select PDA/AP and locate the downloaded twrp_3.0.7_j2lte.tar file and select it. Now, connect the device with computer using data cable.
Step 5 : After connecting the device, note that the odin shows the "added" message. Then select "start" button and sit back and relax. It will show you the "pass" message and your device will restart automatically.
Step 6 : After this, download "superSU experimental.zip" from the link. And move it to root of your sdcard.
Step 7 : To see your new custom recovery , boot into recovery mode by pressing and holding the volume up+power+home buttons and then you see the TWRP logo and it will turn you to the home page of the recovery. Select the "install" option and locate the "supersu v2.60 experimental.zip" file and select it and flash it by swiping right from the left and the recovery shows the message "successfull". Then select "reboot" and then select "system" to reboot the device. Wait for the device to reboot and switch off and again it reboots automatically. Then, you see the "superSU" app installed on your device. Downoad "Root Checker" app from playstore for propper root verification. (During the boot, you see "kernel is not seandroid enforsing" message; don't worry, it doesn't affects on device.) Now, you have successfully installed TWRP Recovery and Rooted your Galaxy J200G.
KEEP SMILING!!!!
Link for Firmware(for those who's firmware is latest ones for downgrading): Goto boycracked.com/2016/03/31/officialsamsung-galaxy-j2-sm-j200g-stock-rom/ and download.
NOTE : YOU MUST SELECT FIRWARE : J200GDDU1APB1.
Link for Odin : Goto drive.google.com/file/d/0B-cLs7AIeb37ZWxSMl9EaGQ0Ukk/view and download.
Link for TWRP Recovery: Goto dl.twrp.me/j2lte/twrp-3.0.2-0-j2lte.img.tar.html and download.
Link for SuperSU : Goto download.chainfire.eu/745/SuperSU/BETA-SuperSU-v2.60-20151205163135.zip and download.
Link for Samsung driver for J200G : Goto www56.zippyshare.com/v/plQkPh9p/file.html and download.

Hi community.
I have SM-A115F/DSN (Galaxy A11) running Android-10.
Can I root it and, if so, how?
Maybe someone has already rooted the same device.
I am a beginner and I need a complete step-by-step method. Thank you in advance.

Thanks for your answer. Yep, I have seen this site. I even left a comment there that instruction contains a broken link. You can use your mouse wheel (if using desktop) or swipe down (if using smartphone) to scroll down to see comments there. They fixed the issue, but they still have instructions that does not work. I apologize for mistrusting your link, but I am afraid to follow the incorrect instructions on this site. Since people say that this can lead to the fact that the phone stops working at all. No offense.

No wiping during process
I already backed up everything but I don't want to wipe my storage. Losing data by accident is one thing but when it is part of the process I just can't do it.
So how do I root my a11 samsung galaxy without losing data and obviously bricking the device?
Feel free to email me.
I also don't have access to a pc currently but may buy one in the coming weeks.
---------- Post added at 05:22 AM ---------- Previous post was at 05:19 AM ----------
Bootloader wipes the storage for some reason. How do I prevent this and still root my device?
The thought of a wiped drive/phone almost triggers a panic attack even if everything that I want is backed up.
@Ulrika8
You don't need to unlock phone's boot-loader etc.pp in order to root its Android. Look inside here.

Actually that won't work for me because I have android 10. Samsung Galaxy a11. Also how can I upload a screenshot of my device information?
Is there a number I can call for technical support in regards to rooting. I am in California USA.

Also had the same question. Did you manage to root yours? NB: On Android 11
A11 on Android 11. Have tried every method online and for the life of me can not root my A11 without getting boot loops nor can I successfully flash TWRP..
Any tips...
Hello all. I have a G570Y which was accidentally updated to the August 2020 security patch system. I can't downgrade the firmware to the previous version because this version has changed the binary to U3 (earlier version U2).
You also won't find OEM Unlock Toggle in Developer Options or it is called RMM / KG State set to Prenormal on this new firmware.
However I have managed to make this device ROOT. This is how I do it.
STEP 1 - Bring up the OEM Unlock Toggle
URGENT !
You have to connect to the network and ignore / disable Samsung Gift applications
Show Developer options by opening the Settings menu> About phone> Software information> Tab 7x on the Build number and returning to the Settings menu, the Developer options menu is under the About phone menu.
Select the General management menu> Date and time> Turn off the Automatic date and time option, then set the date manually. Shift the month counted 3 times backward, ignore the date, choose the one you like (This method works best without frustration)
Select the Software Update menu then turn off the Download update automatically option, then restart your phone.
Open the Settings menu> Developer options> OEM Unlock is visible. Repeat for the OEM Unlock process by sliding the toggle.
If it doesn't appear, repeat no, 1,2,4. When it appears you can continue to the next step.
STEP 2 - Flash Root Kernel
URGENT !
You must backup all your internal data before doing this process.
i found a halabtech website which uploads root kernels for G570 F/M/Y series with U3 binary. You must use ODIN to flash this file in AP.
Link download :
Root Kernel G570M - Odin
Root Kernel G570F - Odin
Root Kernel G570Y - Odin
Download the latest version of Odin here:
Odin3-v3.14.4.zip
After installing the Root Kernel you will find a long booting and a black message appears on the device screen saying that there is activity without permission, wait a few moments until you can press the Reset button at the bottom of the screen. The device will reboot and erase all data.
After that you must install Magisk Manager and update the latest version of Magisk Root.
STEP 3 - Install TWRP
Download the latest version here:
TWRP - J5 Prime
Download RMM State Fix 8.1 and 9.x OEM Unlock Fix here:
RMM_Bypass_v3_corsicanu.zip
Reboot phone to Bootloader (hold Vol Down + Home + Power button)
Open Odin then enter the TWRP file in the AP box, untick Auto Reboot on the Odin Option menu. Click the Start button.
Turn off the device then enter TWRP (hold down the Vol Up + Home + Power button), select the Wipe menu> Format Data. Then back to the TWRP start menu and select Reboot> Recovery. (This is because the phone's internal sdcard is not readable / 0 mb)
You can only copy files and flash RMM State Fix 8.1 and 9.x OEM Unlock Fix after reading the internal sdcard in TWRP.
I've managed to make a permanent ROOT on the G570Y and removed all the bloatware. I hope this helps all of you.
Special thank to :
Team Win Recovery Project

Without you everything will not be easy.
May Allah reward all good to you.

With the LG Unlocker site gone for good (see above), the only way to unlock the bootloader is the DirtySanta/DirtyElf process. This can well vary by device model, so read the instructions that go with the phone model. It works, and in some cases will even unbrick the device.
With that directive in mind, and noting that my device is an LG V20, model US996 (aka. Carrier-Unlocked US version), here is a capsule summary of how to accomplish the task. You'll still need to find and download the necessary files for your device if it is not an US996 V20 and follow those directions, but this should give you the gist of what's involved:
Unbrick and/or restore LG V20 (US996) to stock
Source: https://forum.xda-developers.com/t/restore-v20-to-100-stock-even-for-bricked-devices.3524903/
Install LG Driver, LGUP, Uppercut, and supporting DLLs
Download .KDZ (Stock ROM) file
Completely Power off the device
Connect USB cable into PC
Press and hold VolUp
Connect USB to device
Device will enter Download (Firmware Update) mode
Release VolUp
Launch LGUP via Uppercut
Click "..." to locate and select the .KDZ
Click "UPGRADE"
Click "Start"
Wait for completion
Disconnect device
FYI, Stock ROM files can be downloaded from the Stock ROM repository at https://lg-firmwares.com/
Unlock Bootloader
Source: https://forum.xda-developers.com/t/v20-h915-us996-dirtyelf-bootloader-unlock-and-root-guide.3568013/
The scripts listed in the following directions are bundled in the DirtySanta/DirtyElf archive "kit" along with everything else required to get this done. The named scripts come in Unix/Mac (.sh) and Windows (.bat) form:
Enable Developer options
Enable OEM Unlock
Enable USB Debug
Connect device
Always trust the security key
Set USB to MTP (File Transfer) mode
Copy rooting folders to internal storage
Enable GENERAL>FINGERPRINTS & SECURITY>Phone Admin/Unknown Sources
Install terminal emulator APK
Open unlock kit directory
Execute runmefirst.bat to open "Trace" window
Execute step1.bat
At prompt:
run-as con
chmod 0777 /storage/emulated/0/*
On device:
id
If the string contains "context=u:r:untrusted_app", then on device:
applypatch /system/bin/atd /storage/emulated/0/dirtysanta
Wait for prompt in "Trace" window
Execute step2.bat
Device will reboot into fastboot mode
Execute step3.bat
Device will reboot; remove battery
Hold VolDn and press Pwr
Release Pwr briefly when LG logo appears, then re-hold
Release Pwr and VolDn when reset appears
Select Yes 2x to restart device
Device will display a "corrupted system" screen and then load TWRP Recovery
BACKUP > Select Boot, Recovery, System, EFS, Firmware
WIPE > FORMAT DATA
WIPE > ADVANCED > Dalvik, System, Data, Cache

Proceed with the new ROM's installation instructions.
When running the TWRP backup, make sure you save that to an SD card > 16 GB
There is a method using LG LAF tool under mAid. mAid replaced the older FWUL which is now defunct. Here are the instructions I have (copied from other post). Remember to replace mAid for where it says FWUL:
Boot from your FWUL USB stick.
Put your phone into download mode. With the phone powered off, hold vol up and plug in the USB cable. You do not need to touch the power button -- the phone will power on and enter download mode.
Once booted, login. The password is: linux
Double click the LG folder that is on the desktop
Double click on LG LAF (runningnak3d) icon and you will be at a terminal prompt.
The following are the commands that you enter into that terminal. You can copy / paste them if you like.
[FONT=Noto Mono, monospace]git pull
git checkout h918-miscwrte
./step1.sh[/FONT]
When you are told to, pull the USB cable, and the phone will power off. You now have TWRP on your laf partition.
It must be said again, flash TWRP onto recovery so you can easily get to TWRP.

One thing to be aware of when trying to root/flash is the Anti-Rollback version. Here is some info (copied from other posts):
Qualcomm CPUs have a section dedicated to QFPROM (Qualcomm Flashing Programmable Read Only Memory). When you write to that area of the CPU, it can never be written to again. They are called Qfuses. When they are blown, they can't be "unblown". It contains several things, the PBL (primary boot loader), the RSA key used to verify the secondary bootloader, the Qfuses that control various aspects of the phone, and a LOT of other settings.
ARB is also stored in QFRPOM. There can be 16 values 0x0 to 0xF -- so lots of room to increment.
When the phone boots, the PBL loads the SBL(XBL) and compares the ARB version number of the SBL to the version that has been blown into the CPU. If the version is less than what is stored in QFPROM, the PBL immediately goes into 9008 mode -- you have a brick (at least with the V20). If the version is equal, it loads. If the version is greater than what is currently in QFPROM, it blows the next Qfuse, and ARB is incremented, and then it loads.
The SBL is signed with an RSA cert. The PBL uses the RSA key that is in QFPROM to verify the signature of the SBL. If the SBL has been modified, or the RSA sig doesn't match, the PBL goes into 9008 mode.
H91810O and below is ARB0
H91810P to H91810U is ARB1
find ARB (on stock ROM)

Here also is a thread that explains why the older "dirtycow" flash method no longer works.
