Samsung released the Galaxy J7 2017 edition back in July 2017, and it’s easy to say that it was one of the most sought-after device among users looking to buy a device without breaking their bank. But we know what else you crave for, well, that is root and TWRP recovery for the device, because once you get fond of the superuser access and custom ROMs, you need these two hacks on your device to be able to feel satisfied with its ownership.
Well, good news then! The Galaxy J7 2017 root, and its TWRP recovery, both are available. Of course, root is fairly easy to achieve on this set once you get TWRP recovery, which became available only now.
Note that this is model no. SM-J730F/G/GM/FD we are talking about, as carriers in USA did enough to confuse the world by presenting SM-J727(x) as J7 2017, which is not correct. SM-J730(x) is the J7 2017.
‘Oreo update for Galaxy A3, Galaxy A5 and Galaxy A7‘
Now, with Google having released the Oreo update already, we know many of you are kinda just waiting for the Android 8.0 custom ROMs to drop for the device too, which we think should arrive in due course. Further, the device is fully eligible for the Samsung Oreo update too, which should arrive as an OTA sometime in Q2 2018.
Anyhoo, enough talk, let’s go about how to root Galaxy J7 2017 and install one cool TWRP recovery on to it.

- Note: Only the Galaxy J7 models powered by Exynos 7870 processor are eligible with this TWRP recovery and root guide.
- Don’t try on any other device whatsoever!
Important: Check your device’s model no. on its packaging box, or in Settings > About device. BTW, be sure to use an app like Droid Info to make sure that your device’s model no. is the one given above. If you don’t see the same model no. and codename, then DO NOT try this on your device.
Warning!
Warranty may be void of your device if you follow the procedures given on this page. You only are responsible for your device. We won’t be liable if any damage occurs to your device and/or its components.
Backup!
Backup important files stored on your device before proceeding with the steps below, so that in case something goes wrong you’ll have backup of all your important files. Sometimes, Odin installation may delete everything on your device!
Step-by-step Guide
Step 0. Make sure you have enabled the OEM Unlock. For this:
- Go to Settings > About phone, and then tap ‘Build number’ 7 times or until you see the ‘you’re now a developer’ message pop up.
- Now go back to Settings, and into Developer options. Now, look for OEM Unlock, and select it using its toggle button.
In case you can’t find the OEM Unlock option in Developer options as given above, ignore this step. Maybe this is not available for your device, which is not bad. We’re happy to not ahve it, actually. However in case you run into error called ‘Blocked by FRP lock‘, then it means you have the OEM unlock option, and you need to enable it.
Step 1. Download TWRP, SuperSU and Odin file from above.
→ Transfer the root kernel and SuperSU file to your Galaxy J7 2017. Keep Odin and TWRP file on PC.
Step 2. Install Galaxy J7 2017 driver (method 1 there!) first of all. Double click the .exe file of drivers to begin installation. (Not required if you have already done this.)
Step 3. Extract the Odin file. You should get this file, Odin3 v3.10.6.exe (other files could be hidden, hence not .
Step 4. Disconnect your Galaxy J7 2017 from PC if it is connected.
Step 5. Boot Galaxy J7 2017 into download mode:
- Power off your Galaxy J7 2017. Wait 6-7 seconds after screen goes off.
- Press and hold the three buttons Power + Home + Volume down together until you see warning screen.
- Press Volume Up to continue to download mode.
Step 6. Double click on extracted file of Odin, Odin3 v3.10.6.exe, to open the Odin window, as shown below. Be careful with Odin, and do just as said to prevent problems.
Step 7. Connect your Galaxy J7 2017 to PC now using USB cable. Odin should recognize your Galaxy J7 2017. It’s a must. When it recognizes, you will see Added!! message appearing in the Log box in bottom left, and the first box under ID:COM will also show a no. and turn its background blue. Look at the pic below.
- You cannot proceed until Odin recognizes your device and you get the Added!! message.
- If it doesn’t, you need to install/re-install drivers again, and use the original cable that came with device. Mostly, drivers are the problem.
- You can try different USB ports on your PC too, btw.
Step 8. Load the TWRP file into Odin. For this, click the AP button on Odin and the select the TWRP file in .TAR format.
Step 9. Make sure Re-partition and Auto Reboot checkbox are NOT selected, under the Options tab. Don’t use PIT tab either. Go back to Log tab btw, it will show the progress when you hit start button in next step.
Step 10. Click the Start button on Odin now to start flashing the TWRP on your Galaxy J7 2017. Wait till installation is finished, after which, you’ll get PASS message as show below upon successful installation from Odin.
- If Odin gets stuck at setup connection, then you need to do this all again. Disconnect your device, close Odin, boot device into download mode again, open Odin, and then select the TWRP and flash it again as said above.
- If you get FAIL in the top left box, then also you need to flash the TWRP file again as stated just above.
Step 11. Your Galaxy J7 2017 would remain in download mode itself — it won’t restart automatically because we turned off Auto Reboot in Step 9 above, to buy you time to boot into recovery mode from here. Reboot into recovery mode to access TWRP recovery. (Read both points below of this step before doing this step.)
- Press and hold Volume down + Home + Power button together until screen goes off, but once screen goes off, do this quickly: while still holding the Power and Home button, press Volume Up button in place of Volume down button to reboot into recovery mode.
Step 12. In TWRP, tap on Install button, and then select the SuperSU root file. Then do the swipe action at bottom to install the kernel. Tap on Back button to go back to main screen of TWRP.
Step 13. Tap on Reboot System button to restart your Galaxy J7 2017, which will now have root access. Once the device restarts fully and boots into Android OS, you must have a new app called SuperSU, which manages root access for apps, letting you control superuser access which apps and services have it.
→ That’s it. Enjoy the TWRP and root access on your Galaxy J7 2017!
To access TWRP recovery, you have to reboot into recovery mode:
- Power off your Galaxy J7 2017. Wait 6-7 seconds after screen goes off.
- Press and hold the three buttons Volume up + Home + Power together until you see Samsung logo on the screen.
