Recently picked up an Samsung Galaxy S4 Tab, the verizon-branded model. I'm having a hard time getting the OEM Unlock option to appear in the Developer Settings.
It's still running Android 8.1. I haven't done any system updates, just did another factory reset trying to get that option to appear.
The whole reason I wanted an GT S4 was to put Kali Nethunter on it, as it is the preferred tablet platform for Nethunter.
I'm not a verizon customer, so I don't know what recourse I have with them. I have put a SIM card from an older phone in it for the time being, but I dunno if waiting a week will even work if I'm not on the verizon network at all.
Any suggestions? Thanks for any help.

Previously I purchased a samsung galaxy note 2 from T mobile and I factory unlocked it by following instructions online with service menu and so on.
But now I've purchased this galaxy s4 from Globe carrier in the Philippines and I cant do the same thing as I did with my note 2 before.
I cant access service menu when I type *#0011# I cant go back from service mode menu and cant access any options.
I saw a lot of instances of this with different carriers but I havent found a solution yet.
My questions:
1. Is it possible to flash a firmware from a different carrier to my i9505 globe tel locked? Im scared to brick my phone so I havent tried yet.
2. If my above question is possible, will I be able to access service menu by then?
3. Is it possible to unlock phone by rooting?
Thanks very much! Happy new year!

Ok so in order to do this, you must replace your current sim card with your new carriers sim card. Then, call your carrier and ask for an unlocking code when you are prompted to the unlock code screen. Then just tap okay and your Samsung S4 should be unlocked! Good luck. Thumbs this up if it helped
I have been trying to unlock a Samsung Galaxy S9 T-Mobile model SM-G960U to use it on local carrier (Ecuador) with no luck (I have use doctorSIM service too)
After booting the phone a got a message:
Security error.
This phone has been flashed with unauthorized software is locked. Call you mobile operator for additional support. Please note that a repair/return for this issue may have additional cost.
Trying to use the T-Mobile device unlock app, then a screen shows up with a message "Your device is network locked at this time, which prevents it from operating with other compatible wireless networks. To inquire about your device's unlock eligibility please continue" but after tapping the Continue button there is not option of permanent unlock, I got a message saying: "Server not responding. Please try again later."
I have trying to install de stock firmware G960USQU7ETG3_G960UOYN7ETG3_TMB (Android 10) downloaded from Frija using the Odin tool, doing a factory reset, wiping the cache, doing a NAND Erase with Odin, but the security error still shows up.
The device is able to browse on websites using Wi-Fi, what should I try next?
paid services are the only way. You won't get help on that here. They employ a different type of lock than most devices.

I don't know all the ins and outs of tmobile unlocking (not a fan of their service). However, I recently had in hand a paid off s9+ which was still locked. I ran the unlocking app multiple times over the course of a few hours. Each time it came back with an error (unsuccessful or something to that effect) when I tried the permanent unlock. For each attempt the tmo sim with active service was still installed. Eventually it did finally unlock. I'm not sure if a tmobile sim with active service is a necessity. Probably is as it has to authenticate the account for unlock eligibility.
I have a Verizon Samsung Galaxy S9 Sm-g960u and needed to switch to T-mobile. I had no problem switching from one carrier to another because I was told that all Samsung Galaxy S9 devices came factory unlocked. I bought a T-mobile Samsung Galaxy S7 Note from a friend and tried using the T-mobile app to unlock the phone I think there was a problem so he just called T-mobile and explained that he sold his old phone blah blah blah and since he owned it they just unlocked it right over the phone, no problems or issues.
Good day everyone!
I recently got a new phone (Galaxy S21), and I saw that you can bring your own phone to Tracfone, so I gave my Verizon S9 (SM-G960U) to my wife (to upgrade her old Samsung Tracfone phone).
We bought and installed the Tracfone SIM card and everything seemed to be working (she could make and take phone calls).
Little did I realize that Tracfone actually also uses WiFi for phone calls, and thus making and taking calls was not using Tracfone's network while connected to WiFi.
When we started researching why her phone did not work outside the home, we found that the CSC is still set to VZW.
This S9 has the latest April 2021 security update from Verizon (Android 10).
I downloaded an older stock Tracfone ROM, but Odin fails with an Auth error (presumably because the phone is not unlocked nor rooted, and the bootloader is locked).
I also tried just flashing the CSC with a Tracfone CSC, but it also failed with an Auth error.
All of the research I have done to this point indicates that Samsung makes flashing Android 10 Galaxy phones very difficult, and I suspect that I am screwed.
Should I put the Verizon SIM card back in and beg Verizon support for an unlock code? Will that even help?
Why doesn't the Tracfone SIM card override the VZW CSC? I thought the SIM card would take precedence.
Thank you in advance, and I hope I am not repeating another thread (I searched, but I couldn't find anything related to changing CSC or rooting a Samsung Galaxy phone running Android 10).
P.S. I have no objections to performing a factory reset of the phone if it will help.
P.P.S. I would like to run the stock Tracfone S9 image so my wife can get the OTA updates, but I'm willing to do whatever to get it working (I would even be happy with running the existing VZW firmware as long as it works).
I've purchased a Verizon unlocked Galaxy s21 FE and am trying to use it on Mint Mobile. It connects for about 5 minutes but then 5G and reception go to 0 and a message saying "sorry, your device can't be activated on another carrier's network right now. For help, contact Verizon." pops up. I believe I could solve the issue by changing the CSC region code but don't want to trip KNOX. These are things I tried:
Phone Dialer */# commands did not work to change CSC or even show IMEI. Might be Verizon locked or Android 12 locked.
Flashing XAA region firmware did not help the issue even though it cleared all verizon bloatware and splash screen.
Flashing another carrier's (Tmobile) firmware and accidentally updated my bootloader to Binary 3 .
I believe that a potential fix is to flash android 11 from Verizon and maybe the phone dialer commands will work to change CSC.
Anyway, this has been a real headache and I just want to use my phone like normal on my selected carrier. Be careful with phones that have VZW region codes!!!
EDIT: I have the SM-G990U Snapdragon US model of the Galaxy S21 FE. Android 12 and 4.1 UI.
EDIT 2: The OEM Unlock Option does not exist on my phone even after becoming a developer.
You ever able to get this working?
Hi l. Just got a XT2201-4 and have it activated on Fi despite it being a Verizon phone. It is giving me warnings about auto updating and must reboot, and a bunch of Verizon B.S. apps etc. Build is S1SHS32.55-78-10-3. Is it possible to unlock bootloader on this phone or to flash a stock ROM without any carrier B.S.? If not, I might return the phone although the price and specs were all great. Thanks.
Also is the X30 Pro and Edge+ 2022 the same phone?
