Hi! I've been meaning to root and change rom on my Galaxy Tab S 8.4'', it's been painfully slow, even more now that i have a OnePlus 3.
The thing is, it's sim locked to a carrier in my country (Portugal - MEO), i know i can just root it, flash TWRP, really easy.
The question is, can i just change rom? Will it unlock just by that? Will it bootloop forever?
Thanks in advance!
Edit: I know to unlock the sim, i have to do something called "network unlock", but i was just wondering if i can change roms without doing that, i don't care if it stays sim locked, i don't want to change the sim, just the rom.
Edit2: Just to clarify, i don't care if the sim stays locked, i just want to change roms!
i have tried reading multiple threads but i seem to be getting conflicting answers.
can you buy an s20 variant from verizon at all and be able to root it and unlock the bootloader etc so that you can end up using magisk and also xposed?
or do you need to buy a special version of the s20 and port it to verizon somehow?
if there is a special variant of the s20 that i can get and use on verizon, can anyone give me the exact model number and then an idea of where/how to get it?
unfortunately i am stuck with verizon as i'm on a plan with family members where i am the head of the account so getting rid of verizon really isnt a possibility for me.
i just want to get a really good 5g phone because there is 5g where i live. but i want to root it and have all of the tools i have with my current phone which is an LG v20 - i love the v20 but its getting old obviously and slow and its driving me crazy with how slow and laggy it feels.
i appreciate any help on this topic!
ok so i'm bumping this
can i buy an s20 ultra from amazon that says unlocked
https://www.amazon.com/Samsung-Unlocked-Fingerprint-Recognition-Long-Lasting/dp/B082XYGR2C/
something like this that says unlocked?
would i be able to root this and use it on verizon?
i just dont want to spend that kind of money on a phone and not even be able to root it and unlock the bootloader and not be able to put TWRP and magisk and xposed and etc
unlocked means carrier unlocked as for the bootloader https://forum.xda-developers.com/t/sampwnd-usa-model-bl-unlock-info-u-u1-w.4201689/

thanks for that link! that is exactly what i was looking for!
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?
I bought a Canadian variant Samsung Galaxy S20 (Snapdragon) yesterday, and knew that the SIM reader slot was faulty and needed to be replaced. I had assumed that I could just use eSIM, but didn't realize that the Canadian variants have it blocked.
Any advice on how to enable it? Can I maybe flash international firmware onto it to have the SIM card manager and enabling of eSIM, and if so, which one and how? Using Odin? Or a modified Odin? Do I need a working SIM reader?
Or maybe I change the CSC? If so, any instructions on how to do it with my variant?
Or do I need to root? If so, any instructions on how to unlock the bootloader (I don't have the OEM unlock option in Developer Options) if I am on One UI version 4.1? Or do I need to downgrade? If so, how do I downgrade?
I really don't want to have to tear this phone apart and resolder on a new SIM reader slot. It's a really great phone and the nicest one I've owned.
I'm not sure where to start.

SM-G981U1 XAA seems to be still on Android 12. I'll wait until 13 is ready before I attempt. What is "nr sa"? Thanks.

I read that if the W model is flashed with the U1 firmware, Samsung Pay can no longer have Canadian credit cards added. Can someone verify? OneUI 5.1 is being tested on the S20. We can only hope Samsung enables eSIM for that release.
W model has 13 release now. Does it still not support esim?
I was on the U1 model Android 12 in Dec 2022 (With esim enabled) and updated to the W model Android 13 firmware figuring it should have esim enabled however it did not.
I used odin to switch to the Android 13 U1 firmware but it did not enable esim (I used the home_csc). I flashed the older U1 Android 12 firmware which did enable esim again but I had to factory reset the phone due to a boot loop.
After reseting and doing an OTA update to Android 13 the esim stayed enabled and I restored a backup using smart switch for my apps and settings.

So in summary, to get eSIM in A13 U1, first odin install A12 U1, and then OTA to A13? The A13 U1 was uploaded yesterday ( link ).

It may work if you use csc instead of home_csc which would reset the phone straight out. I used home_csc which kept my Canadian firmware settings and likely csc

Does Samsung Pay work with Canadian credit cards in your A13 U1? That's the only requirement holding me back from converting. Samsung Pay+Google Wallet cover 90% of the places I regularly shop at.

I only use google wallet so I never tried samsung pay before. I installed samsung wallet and seems it wants a us zip code.
Ok guys so i bought Samsung Galaxy S22+ in Korea. I am from Europe. Reason why i bought phone in Korea was it was like 20% cheaper then in EU + it have Snapdragon instead Exynos.
But as i came back home i was in for a suprise, coz i tried to set up dual sim for the phone, but then i realized i cant do it. SIM card tray where u put physical SIM cards have only 1 SLOT, 2nd slot that was supposed to be on the back side is slighty modified so SIM card cant fit in, also there is no writing SIM2 like its written on fron (SIM1).
Also phone doesnt have support for eSIM, i cant open SIM manager or anything related to SIM cards in settings of my phone.
Dual SIM is important for me coz i use 1 SIM for SMS and phonecalls, its my number, and 2nd SIM is for internet. We are able to buy internet SIM here that have 60GB of data per month and its super cheap, like 7 EURO, so running dual SIM is super cheap version. If i buy internet via my regular phone providers where i can use phonecalls and SMS combined, it cost like 3x more.
SO yeah, i mean i could go for more expensive version and just have 1 SIM but its stupid coz 1 of reasons was i bought that phone is to run it DUAL SIM, i have also my old Huawei P30 pro working just fine, and now i feel dumb for buying another new phone that was meant to replace my old and its not working 100% correctly...
Can i modify my phone to make it work? Install EU version of Android or something? I would rly like to make it work, although even if i make it work i am not sure if my Internet/Phone service provider support eSIM so i swap this main physical sim with eSIM and then use internet one as physical. But ill deal with this later. I just wanna try enable eSIM first if its possible and have dual sim support in my settings.
Any help is very appreciated!
Best regards!
