Need help with SIM Network Lock (SM-J700M)

Alright, so, last weekend I got a new Samsung Galaxy J7 with Android 6.0.1. The first thing I did was rooting it. It was all going fine until I accidentally unticked the "OEM Unlock" option on Developer Mode, so when I rebooted it, it had an FRP Lock.
I used a Latin American firmware to be able to boot it again. At boot, there was this "entel" logo, and this seemed to have changed my IMEI because my phone always said Network Unavailable. I didn't check the IMEI prior to rooting it, but I noticed the printed one and the one shown on the phone weren't the same... but this isn't the real problem.
Originally, the phone was unlocked (no specific carrier/operator holding it), and I somehow "fixed" the Network Unavailable thing by erasing the efs folder on root... well, it was a longer process than just deleting it, I backed up the folder and copied some files (some might know what I'm talking about). After that, the IMEI was the same than the printed one, but, my phone is now network SIM locked!
I have to input a code to unlock it. I did some googling and apparently only the carrier can give it to you, so I tried 3 different carrier SIM cards to see if any of them were the carrier's, but none of them worked as accepted,and I don't know what carrier could it be... I'm even worried it may be a Latin American one (from Chile or Argentina maybe since that's where the firmware used was from) and I won't be able to get it.
I know there are websites to get a code, but I don't want to pay so much and risk getting scammed.
I tried to see if "entel" was a carrier to unlock it, but it didn't help.
Also, when I try to choose a network on Mobile Networks settings, the only available one is AT&T (which I don't use/have a SIM of), but when I accessed their website to unlock, it said my IMEI wasn't registered as theirs apparently.
Then, I also tried using Samsung's Smart Switch application on PC with the Device Initialization option, but when I try to use the firmware from that I get a SW REV. Check Fail.
I might be wrong, but I feel that since messing with the system files/root was what changed it, maybe I can fix it the same way with no unlock code or carrier help.
So, does anyone have advice, or know some other way to reset it? Or do I really have to go get it fixed/unlocked somewhere?

Did you ever get anywhere with this? I am trying to switch carriers from t mobile to boost on the Sm-j700f and I need to unlock it

Anybody with project Fi got their bootloader unlocked or otherwise?

What are people's stories with Pixel 3 on Fi regarding bootloader unlock? Is it greyed out or unlock is working for people?
Quick search only indicated there are open issues in this area and no resolution.

Ordered Pixel 3 from the Google Store with Project Fi, and bootloader unlock is not grayed out on my phone. No idea if that's common or uncommon, just reporting on my device.

You mean you ordered from fi.google.com, right?

Pretty sure I ordered the phone on store.google.com, and specified the Project Fi version, then completed the Fi registration on fi.google.com.

Ordered the Project Fi version from the Google store. Bootloader still locked. Option to enable bootloader unlocking not grayed out.

I ordered mine from Project Fi directly (through the app) and received with the greyed out "OEM unlock". Even after updated and factory resetting, still greyed out.

Just got my black XL 64 direct from Fi, financed, today. OEM unlock was not greyed out and let me toggle it on. Haven't performed an unlock.

I ordered a Pixel 3 from the Project FI/Google Store and received the Pixel 3 with OEM unlocking grayed out. After searching the web I found that some people had received the Verizon version from Project FI. I called FI support and was able to RMA the first phone, I then received a Pixel 3 with OEM unlocking enabled. I was told by support that there was no guarantee that the device I receive would have OEM unlocking enabled, but it was worth it to me and I got LUCKY.
Because I returned it within the 15 day return policy, they were able to guarantee me a new phone and not a refurbished device. I would call support to make sure of this, I had to talk to a manager.

Probably everyone resolved this already, but in my experience Pixel 3s from Google all come with OEM unlocking turned off and grayed out (ie can't be unlocked), at least initially, then during setup, something is downloaded or something is queried that makes the option selectable.
I had 3 of them, 2 from Project Fi and 1 from Google Store. I set up all of them initially not connecting to WiFi, and obviously not connecting to Google Account.
For all 3, I enabled developer options, then found OEM unlocking was turned off and grayed out (not selectable)
After connecting to WiFi and Google account, then the option was selectable.
There is probably a list of serial #s somewhere that gets queried and it controls whether your OEM unlocking option will be selectable or not. Assuming there is such a thing, until that theoretical query is successful, your device will have OEM unlocking grayed out.

oem unlocking greyed out

hi, i bought a oneplus 8 5g from sprint today and i am trying to root it before i load my stuff to it (the bootloader menu mentions its product name is kona).
when i go to developer options, i am able to turn on usb debugging but oem unlocking is greyed out.
Code:
[[email protected] ~]# adb reboot bootloader
shows
...secure boot - yes
device state - locked
Click to expand...
Click to collapse
on the fone.
Code:
[[email protected] ~]# fastboot flashing unlock
FAILED (remote: 'Flashing Unlock is not allowed
')
Finished. Total time: 0.001s
[[email protected] ~]# fastboot oem unlock
FAILED (remote: 'Flashing Unlock is not allowed
')
Finished. Total time: 0.001s

Mine is also from sprint and greyed out.
TF?
Wonder how we enable that feature.

So I just tried to enter recovery mode and it asked me for a password??
I entered MY 4-digit unlock code and it failed.
I pressed "Forgot Password" and it said "You will lose all music, photos, etc..."
I couldn't simply exit the screen. I had to hold PWR+VolUp to reset.
Is that because OEM unlock is greyed out?
Edit: It is Recovery Mode that is password protected. Why?
Edit 2: It had to do with having a secure pin. Turn off secure unlock and you can get into recovery. OEM Unlock was still greyed out.

I believe oem unlocking is greyed out because you are still simlocked. If you just got the phone today there is no way you are unlocked either the XDA way or meet TMobile criteria for official unlock.
I saw another thread where the password was oneplus on something in the bootloader. Not sure if this was the place but can't hurt to try.
Sorry if either of these things is incorrect.

thanks to yoo both. i bought the fone outrite (no lease plan) so its mine.
my previous fone was an essential so I never knew the carrier got in the way of unlocking the boot loader... but i
remember having to wait til after payoff to get the fone carrier unlocked ( which is different). i gotta' admit, i have no idea what all these password and codes being mentioned are (wow, a lot has changed in three years).
i came across this site in my searches but i dont have an unlock code ? not sure the purpose of this site since fastboot mode doesnt have internet access ?

You need to call Sprint or--
From the Home screen, swipe up on an empty spot to open the Apps tray.
Tap Settings > Wi-Fi & Internet > SIM & Network > Advanced.
Wait while the device connects to the server.
Choose the desired device unlock type:
Permanent Unlock
Temporary Unlock - requires a mobile data connection
Wait while the device requests the unlock.
If successful, restart the device to apply the settings.
Permanent Success
Temporary Success
If you do not restart the device, a persistent alert will appear in the notification tray. Then go to Oneplus/unlock token. You have to wait usually 7 days for them to send an "Unlock bin.file. Then look around on our sites on how to unlock your phone. Hope this helps.:highfive:

^thanks, it says that it is not eligible for carrier unlock which is strange becuz i bought the fone (not on a payment lease). stranger that i dont know what the carrier unlock has to do with the bootloader (to me, it sounds like the volume knob on a car stereo causing the engine to overheat) ?
edit:
i called customer service. they told me i have to wait 50 days. they transferred me to tech support so i am waiting.

Mine is also locked for 50 days and still on lease.... Damn

I'm with sprint as well. My device is paid off and I've had it for over 60 days. I've been getting jerked around by these (can't say the real word or I'll get another warning) very intelligent and helpful experts. They start helpful as all hell then soon as I mention the unlock they get real sketchy and I end up transfered or mysteriously disconnected. I got disconnected from a man named Kenneth earlier today, it reconnected to a Jose who said hello my name is Ralph.
I finally asked a woman named Alysha why this was so damned difficult. The device is mine. I meet all criteria, and it's the damned law they can't deny me. She said I must cancel the phone line to make it "free" to unlock.
Bout ready to spaz out. Can anyone please help or anything?

Force bootloader unlock for T-mobile 3a?

So I just ordered a Pixel 3a today and it's the T-mobile locked version. Now I think I might have messed up because I just read that the T-mobile version cannot be bootloader unlocked or even flash factory images (or beta?). This honestly didn't even cross my mind because I thought Pixel devices were always fully open and is a main reason why I wanted it.
My question is if there is anyway to bypass this restriction and run the Google factory image? When I got a T-mobile OnePlus 6T there was a tool that allowed me to flash the factory image and then enable bootloader unlocking. I've been searching online but finding conflicting information that is outdated from a year ago.
Edit: What happens if you adb sideload an image with the bootloader locked as described here? https://developers.google.com/android/ota

My pixel 3a is the T-Mobile version. I was able to unlock the bootloader with zero issues. What seems to be the hangup on your end? I've talked to a few people who have had similar issues, and they stated that OEM unlocking was unavailable in the developer options menu. Is this where youre getting stuck? Or does the problem occur in fastboot when you actually attempt the unlock?
If the issue lies in the developer options menu, there's a workaround that I'll have to find for you. But i *think* what is happening is when you do a factory reset, it installs the generic image -- but as soon as it boots up, the Tmobile Sim causes carrier specific settings/software to be overlayed and effectively blocking the "OEM unlock" setting from being toggled. Without researching it, I believe the solution to your problem is to remove the sim card, then do a factory reset. Boot it up, go through the setup without the SIM physically installed. This should theoretically keep the the option to enable OEM locking available to be turned on.
I bought mine through T-Mobile, used it for 3 months and then asked to have it sim unlocked, which they did. At that point, I installed the verizon Sim card, did a factory reset, and the option to unlock the bootloader became available. So the method I laid out above, should work for you. If not, I'll actually dig around and get ya set up.
Let me know how it turns out, k?

Cannot find OEM Unlock for Samsung galaxy s21 + 5g

Last month, I decided that I wanted to try rooting my Samsung galaxy s21 + 5g (model name SM-g996u), and I got as far as unlocking the network before I hit a snag. In all of the tutorials I have looked at concerning how to root my device, they all keep saying that I need to OEM Unlock my phone under the developer settings. However, as the title of this post would indicate, that setting is not present in the development settings. I have just about lost my damn mind trying to find and enable this setting via online tutorials, and I keep coming across the same suggestions: configure date/time setting so that it is not automatically set, manually set the date back a couple of months, go to dev settings and disable auto-update system setting, disable 'Download updates automatically' setting in software update (this is the only step I was not able to follow because that setting appears to have been removed from more updated version), and restart the device. I even tried removing my sim card, resetting my phone, and retrying the previously outlined steps. Nothing has worked. Is there anyone out there that can help me with this? Any info would be great.

Is device leased from a carrier, e.g Verizon? AFAIK by default this phone has OEM Unlock option in Android's Developer Options.

This device(all of the US models) doesn't have the OEM unlock option. As far as I know, these devices have to be unlocked via a paid service from a 3rd party.

Device has been paid off. It is also network unlocked as well. The device was originally leased from Tmobile. I am aware that the setting is supposed to be in developer settings. I am telling you, it is not showing up for me.

May I'm wrong but the fact that the client have covered the contract, doesn't mean that the carrier do that, if a special petition was not presented to them, then, they don't care about. If the device came with a firmware that came with that feature disabled, so it, also, ends its "normal" life with the same featured included (or not) in the firmware by default.
But you could make advantage from the network unlocked condition, switching to a different firmware it would be possible, and, the option may appear.

This may be just a kind of starting point, to have in mind, but that need more research though, I did it in my GN8 but with your device, things may be different.
There are some things you have to check, in the download screen, KG has to be completed, not prenormal or checking, also search for the CSCs that are compatible for your device, this is one of the tutorial, kind of, that I followed https://www.getdroidtips.com/guide-...ocked-firmware-galaxy-note-8-sm-n950u-n950u1/
