You only are responsible for your device. I won’t be liable if any damage occurs to your device and/or its components.

BEFORE YOU BEGIN..

ANDROID BACK UP AND RESTORE GUIDE: APPS AND TIPS

Samsung Drivers

CHARGE YOUR DEVICES

If your android device, or PC, powers off due to lack of battery while the process is underway, it could damage the device. So,make sure both of them are adequately charged and that no power interruption takes place when the process is undergoing — at least 50% battery of the device and laptop is what we would recommend.

OTHER THINGS TO TAKE CARE OF:

└ Use original USB cable to connect your phone to PC.

└ Do not use the procedures given below on Mac (using VMWare) as it works best on proper Windows PC only.

DOWNLOAD FIRMWARE

Download the firmware you want to root. You can get the firmware from either SamMobile’s samsung firmwares directory or just Google the firmware you want to download to get the download link.

Once you’re done downloading the firmware make sure it’s a .tar/tar.md5/.exe file. If in case it’s in .zip format than extract the zip file to obtain either the .tar/.tar.md5/.exe file..

MK3 Firmware

STEP-BY-STEP GUIDE

Once you’ve downloaded all the required files given above, proceed with the instructions given below to get a knox-free root for your firmware using the URDLV (Universal Root de la Vega) script.

PART 1: Cook the firmware file using URDLV script

We’ll first cook your firmware file to make it compatible with the root scripts we’ll use in further parts of this guides. For this, we’re going to use URDLV script first

Extract the Universal-RDLV.zip file to a separate folder on your computer

└ If you have a anti-virus program installed, and it’s trying to delete some of the extracted files, then disable it for a while and re-extract the Universal-RDLV.zip file again, making sure nothing gets deleted.

Open a command prompt window inside the folder where you extracted the Universal-RDLV.zip file. Press “Shift + Right click” on any empty white space inside the folder and then select “Open command window here” option from the context menu

Now you can either create a FULL modified firmware file or just a CSC file from the firmware you want to root. In this guide we’ll be creating a FULL modified firmware as we believe it to be more reliable than creating a CSC file. Input the command given below in command prompt window and hit ‘Enter‘ to start building your modified firmware file

urdlv full C:\I9505XXUEMJ5_I9505OXAEMJ5_I9505XXUEMJ5_HOME.tar.md5

└ The command above is only for illustration purpose. After “urdlv full”, you must insert the path to location of the firmware file saved on your PC. It can be in either .tar, .tar.md5 or .exe format. To get the path to firmware file, you may drag n drop the file in command prompt window and it’ll automagically pickup the file’s path

Right after hitting enter, you’ll see another command window showing you progress of the file creation, which may take time, so be patient here!

You’ll see a similar window (like below) once the file is successfully created

Your modified firmware file is now created with ‘_VEGA’ added to the end of file name, I9505XXUEMJ5_I9505OXAEMJ5_I9505XXUEMJ5_HOME_VEGA.tar.md5. The file is saved under “Output” folder inside the folder where you extracted files in Step 1

PART 2: Flash the modified firmware using Odin

Extract the ‘odin3.09.zip‘ file that we downloaded from the downloads section above. You’ll get the ‘Odin3 v3.09.exe‘ file

Boot your device into Download Mode:

Power Off your device first. Wait for 6-7 seconds after display is off

Now, press these 3 keys together until you see warning screen: Volume DOWN + Power + Home

Press Volume Up to continue to Download Mode

Start/Run the ‘Odin3 v3.09.exe‘ file that we extracted in Step 1

Connect your device to PC. Odin window will show an Added!! message in bottom left box.

└ If you don’t get the Added! message, then make sure you installed driver as given above, if yes, then uninstall and re-install driver again.

Also, try another USB port on your PC and make sure you use good quality cable, preferably that came with the phone. Reboot phone and PC and try again.

Click on AP button in Odin and select the firmware file we created in Step 5 of Part 1, I9505XXUEMJ5_I9505OXAEMJ5_I9505XXUEMJ5_HOME_VEGA.tar.md5

In the “Option” section of Odin, keep only the “Auto Reboot” and “F. Reset Time” boxes checked. All other boxes in the “Option” section should be kept unchecked

Double check the above two steps carefully. You must not make any mistake with the steps above or else you may brick your device. Your Odin’s screen should look like the screenshot below:

Click the ‘Start‘ button on Odin to start flashing the firmware file, and wait until you see ‘PASS!’ message on Odin’s top left box

When you get PASS! message, your phone will restart automatically. You can then disconnect your phone from PC.

└ If you see FAIL instead of PASS in Odin’s top left box, disconnect device from PC, close Odin, remove phone’s battery and put it back in 3-4 seconds, open Odin and then repeat PART 2 and PART 3 of this guide again

PART 3: Root your device

Extract the root_de_la_vega_sdcard.zip file to get these (one file and one folder):

root_de_la_vega.sh (file)

root_files (folder)

Important! Remove the external SD Card from your device, if connected

Connect your phone to PC and Copy the file (root_de_la_vega.sh) and folder (root_files) to the root of internal SD card on your device

└ It’s very important that you transfer the file and folder to the root on your device’s internal SD card.

Now, restart your device

Once it has restarted, delete file and folder you copied to SD Card in Step 3 above. Yes, delete the file (root_de_la_vega.sh) and folder (root_files), both of them

Important! Now, after you’ve deleted the files, restart your device again.

Once your device has rebooted, Root Access should be there. You can now insert your external SD Card back if you have one

└ Put the external SD card back only after rebooting the device (as instructed in step 6)

CONFIRM ROOT ACCESS

You must have a new app installed now: SuperSU. Check it in app drawer. Also, to check whether you got root access or not, use this simple made-for-this-purpose app, Root Checker.

Note: this will trip knox use it at your own risk
