I got my Samsung J7 Pro 2017 (SM-J730F) unlocked at a local store recently, and I noticed that when the phone was returned to me, it was not only unlocked but rooted as well. The SuperSU app was also installed. Because of the root, certain apps and features do not work on the phone any longer (Snapchat, Pokemon Go, and S Health, to name a few). There is a permanent unroot option in SuperSU and I really want to unroot so that I can use them again, but is it safe for me to unroot? Will my phone retain its unlocked state or will it go back to being locked?
Here's some more info about my phone that may help:
It was bought in another country and sent to mine, and a SIM from my country triggered the lock.
The phone worked normally (except for the fact that it couldn't use the SIM) before I had it unlocked.
My phone needed a code to be unlocked, but I'm not sure if the technician at the store used a code, or if he unlocked it through another method.
I used the phone already before getting it unlocked, but when it was returned to me, it had been factory reset.
As far as I know, no other apps/tweaks had been installed aside from SuperSU.
Thank you!

Hi guys need some help! :'(
I bought a N920-T from shop which was Unlocked and Working for other carriers on Kit Kat rom.
I then installed stock Marshmallow using Odin/Rooted and TWRPD it. And it was fully working with my international SIM. I made a backup of my fully working unlocked Marshmallow with all the items checked (EFS and MODEM too).
Today, somehow my rom got stuck and crashed and I decided to Restore it using backup which I made. Restore got through and everything was back EXCEPT I see "Network Lock:" screen on first time boot up after restoring it.
"The device can be remotely unlocked if eligible. Please use "Device Unlock" application to unlock the device."
Please help! What should I do? Should I launch the T mobile device unlock application and continue it with wifi and see what happens?. Or what?. My device was unlocked and fully working on Kit Kat and Marshmallow too. It means it was officially unlocked right?. PLEASE GUIDE.

It would not hurt anything or make things worst for you if you tried the Tmobile Device Unlock,
it will either network unlock your phone or it won't.
I used Device Unlock on my Tmobile Note 4 and my Tmobile S6 Edge+ and in both cases it
worked fine and unlocked my phones.
Good luck,
Have a great day!

First off the phone shipped with Lollipop not kit Kat. Second a true Sim carrier unlock is permanent and can't be undone as far as I know.
I do remember when you use the device unlock app their is an option to temporarily unlock, I wonder if that's what you had?

Unlocking the carrier lock is permanent
No amount of modding would change it
See if your phone is eligible to unlock: Mobile Wireless Device Unlocking.
From that Application list, tap Device Unlock.
Tap Continue.
Wait while the device connects to the server.
Choose the desired device unlock type:
Permanent Unlock: Permanently unlocks the device.
Temporary Unlock: Temporarily unlocks device for 30 days.
Note: Temporary unlocks must be performed with a mobile data connection. Wi-Fi will not work.
Wait while the device requests the unlock.
If successful, restart the device to apply the settings

I can't even use smart switch to go back to stock
The T-Mobile app didn't work. Permanent and Temporary Unlock said my device is "not eligible". I am confused, when I bought the phone it was working with other Sim and was on Lollipop/Rooted and then I installed Marshmallow T-Mobile Stock Rom via Odin/Rooted and it was still Unlocked then back up which I created was with EFS and MODEM checked in TWRP of Marshmallow. I think the EFS and MODEM option in backup creation and restoring it messed my phone up. But I am still wondering how was it unlocked?. T-Mobile says my mobile is ineligible, maybe shop owner used Z3X Box Samsung Tool Pro or something?
UPDATE:
I decided to use unlock services online. The one I used was unlockbase they have a software that unlocks the phone on-the-go and it requires internet connection. I got my phone unlocked and international SIM working. The question is that if I backup my EFS and MODEM now using TWRP and later restore it will it break the UNLOCK?.They guarantee that their unlock is permanent and modding won't do anything.
Because the unlock they do is of course by altering the EFS/FILES and in that case backing up EFS and MODEM is a safe way to UNLOCK my phone again in future if it somehow gets LOCK again, right?.
For Developers: I have my before/after EFS files backups. Before unlock and after unlock, if some developer wants it for research purposes, I can send it to you for the sake of development.

ask the gentleman to unlock it on xda he's awesome! Never restore it'll cause you to loose unlock under all cercumstances I've learned not a big deal
UPDATE:
I have Saved my UNLOCKED EFS and Modem Files, and upon restoring those using TWRP my phone gets unlocked, tried purposely after locking my device and it works, you just gotta save them EFS Files (unlocking services like via box or online tools edit these files in order to unlock) , they are the real deal lol. Made Several copies of my Unlocked EFS/Modem Files xD
Is there any way to get the unlock app to work on a rooted S8+? Somehow I lost mine and tried loading it from apkmirror but got an error message.
Or is there a way to do it without being on the phone directly like the website?
Reach out to an unlock service. They will one the answer and (for a fee) can probably get it unlocked for you
The Device Unlock App can be found in the App store. Or you can get it from T-Mobile website here: https://support.t-mobile.com/docs/DOC-14011
If you can't get it install like this, do a hard reset and restore your phone's factory settings: https://www.unlockunit.com/blog/how-to-make-a-hard-reset-for-samsung-phones/
if you are doing the carrier unlock, what i did was leave my ATT sim card out of the phone flashed the AQGL TMB stock rom, let it boot up and go through settings,and go into your APPS and it should be there a Pink Icon. Just click on Permanent Unlock and they'll get it done right away as long as you meet their requirements like Device Paid off. TMB does it for free. If you go through an Unlocker theyll charge what, I think i seen these go for like $150.

Truly appreciate you posting the apk but it doesnt work. On their official website they posted the link to unlock app which also has been pulled from app store. I installed Unlocked ROM (Not sim unlocked but Tmobile Crap Free Samsung ROM) it doesnt have unlock app and I would hate to restore phone to tmobile ROM and loose all data. Anyone else has found solution to install device unlock and permanently unlock the Samsung S7 and S7 edge devices? I have them completely paid off and according to Tmobile they should unlock just fine but they are of no help getting that app back on phone without doing complete factory reset from ODIN.
Hello there,
I am wanting to use Google pay with my S8 plus Exynos variant, but I have rooted my device before and now I have updated to Android 8.0 Oreo. I have downloaded the updated through SamMobile and now I get the message: Google Pay can't be used on this device. This may be because your device is rooted, has an unlocked bootloader or is running a custom ROM. As a result, Google can't confirm that your device meets Google pay's security standards. I've always loved Google Pay, so I've been doing a lot of research to try to figure this out, but so far I've come up empty. Does anyone know how to get a locked bootloader or can someone help guide me through the rooting process so I can use Google Pay again as it seemed to work when my phone was rooted on 7.1 nougat?
A little late here but If the device was rooted before then you unlocked the bootloader I assume which Google Pay needs to be locked to meet the security measures you mentioned. Re-lock bootloader and go back to stock firmware through Odin to gain Google Pay back.
I've been having issues with my phone ever since i rooted my A32 (Some samsung features are disabled, Sim Cards don't work), i've thought that this may have something to do with the bootloader being unlocked as i heard that some phones have security measures whenever your phone's bootloader is unlocked
Now, my question is, once i relock my bootloader, will it wipe out the root aswell? or will the root remain?
I am also wondering if there are better ways to solve this issue without relocking
Pretty sure you cannot go back. Sim cards should work though, and some Samsung only features can be restored by Magisk\Xposed (Riru) modules.
