Help Unlocking Service Provider - Samsung Galaxy S10e Questions & Answers

So, a couple of months ago I bought a used S10e. The phone was unlocked by a third party. I assumed that if I installed the latest firmware the unlock will still work. So I installed the latest firmware and next thing I know, my phone didn't had signal. So I contacted the seller and he fixed things up but 1. He didn't flashed the latest android version since it wasn't "available" at the time and 2. I can't update my phone. Apparently phone bootloader is unlocked too. Do you guys know what can I do to unlock the phone by myself and update to latest firmware? Maybe also lock the bootloader since I'm losing some features (Samsung Pass, Samsung Health).

hope someone can help
I have quite the similar issue with my s10e. My phone is only showing lte with full bars. I dont know that I cant let my wifi auto download the update.

Unlocking problems with old phone.

Hi,
I'm currently trying to unlock the aging Samsung Galaxy 3 (i9300).
I currently don't have a phone, and so my girlfriend who has the s6 gave me her old s3.
It's on the orange network, and as said is the i9300 model, which is where the issue lies.
I'm from the UK, and instead of being locked to orange wanted to switch to the Giff Gaff network.
I first headed to their site which gave a rundown on how to unlock the S3 using the usual code you punch into the number pad, but found that I needed to be on an older operating system.
I was on Jelly bean 4.3 and needed to be on a 4.1 variant for this to work.
I downgraded to the 4.1 via the debugging menu and downloading the firmware from Samsungupdates.com and for some reason the firmware I downloaded for my region defaulted to the UK network 3's variant of 4.1.
Now that I was on 4.1, I went back to the unlock steps.
Typed in the code, followed all the steps, but then found out that the steps were for the i747 and not the i9300.
I looked online and came across an old thread on this forum from a few years ago on the subject, which talked about rooting the device and then using another app to do the job, but then others said this no longer worked after July 2013.
I'm not really sure what to do, or weather there's anything I can do.
I'm not even sure if I've messed it up by downgrading the firmware with it now for some reason booting as if the phone was on the three network and not orange.
I know it's an old and unsupported phone, but I was just wondering if anyone had any ideas of what I should do?
Thanks allot.

Hello there XDA Members,
I have a massive problem and I hope someone in this forum is able to help me, I have an S6 Edge SM-G925F, I recently broke my phone and sent it to repair they repaired it and installed firmware that is non EE therefore I lost my WiFi Calling feature, I was like okay let me just flash the EE firmware unfortunately due to the bootloader they installed being newer then the one from the EE firmware it wont let me install (SW B: 2 K: 4 S: 4) this means that the firmware I am trying to install is older and samsung bootloader wont let me, now I want to know if there is a way I can:
1) Downgrade Bootloader or get it to accept this firmware
2)Have EE WiFI calling another way
3)Install EE WiFi calling onto the phone somehow

I would say look for a ee firmware that doesn't include the Bootloader. That way the firmware should load, most mm firmwares will run as long as you have a mm bootloader.

Trying to install TWRP on SM-955F Custom binary(RECOVERY) blocked due to remaining...

Hello.
(backstory, boring) I have an SM-955F from Claro that I've been trying to unlock completely from the carrier. I've had lots of trouble with them and am pending a case with FCC to get out of their claws. In the meantime, I've been trying (without success, hence my posts) to get it working 100% with T-Mobile. I've had T-Mobile for years under a friend's name and couldn't get a device -so I took one from Claro when Puerto Rico was hit with the Hurricane (T-Mobile had no signal for months).
(Little-lot- of info) So, I had the phone updated to Sammobile's PCT 8.0 firmware -G955FXXU1CRC7_G955FOWA1CRC2_PCT-. But it didn't have the OEM unlock. At one point I remember installing TWRP but something happened to the phone and it wouldn't boot up. So, my act of magic (*coughs*, XDA) I found a way to get it back to official firmware (I think at first it was a Germany's 8.0 firmware*can't find the file name*). Anyways, I want to get the phone to have Wi-Fi calling, VoLTE, etc from T-Mobile and, for what I've interpreted, that comes from the CSC files.
Now, I found a thread that uses TWRP+AROMA to get a list of CSC files on the phone and I can just install the one I want. (I don't know if there's an easier way directly from ODIN but I've not found that compatible TMB CSC file for my phone to get the features working, if any).
In any case I still want my phone rooted (I think I triggered Knox, but the phone updated through the Samsung Updater just fine after installing a PCT 7.0 firmware -G955FXXU1AQCC_G955FOWA1AQCC_PCT-. Clearly I'm out of my depth)
(to the point) The phone doesn't want to install my TWRP file. Says "custom binary(RECOVERY) blocked due to remaining installment balance". Obviously it's Claro's side blocking it, I think?. But I can't get them to unlock it (since it's still "theirs", until I get my case resolved or pay their stupid balance. Long story short, Claro's service is **** and I regret not waiting to get my credit approved my T-Mobile)
So, how do I go about it? I read that its RMM blocked. But my state says normal. The OEM unlock only appears on the 7.0 -G955FXXU1AQCC_G955FOWA1AQCC_PCT- firmware (even then it won't let me install TWRP through ODIN). I honestly don't know. I'll appreciate all the help I can get to reach my goal of getting 100% on T-Mobile's features (mainly VoLTE, if possible-the feature is greyed out so I assume it can be activated). Can't even change the radio band on the thing. I read something about using Nova Launcher and having the widgets activate it through "Enhanced LTE" (I think) but that option doesn't appear on the list. I'd also like to delete all remnants from Claro on the phone, bloatware, booting logo and such. Since it's a 955F, I assume one can make it as if international?
Also, please check my previous post, I just realized I forgot to detail something. I did hit that "your phone has been modified, restart to undo process" and I forgot. Maybe that's the root of it all?
Any questions, please do ask. I'd like to get this moving. For now I'll use my Nexus 6 (God I love that phone a lot)
Maybe there's some compensation on this, maybe, if I get it done.
I've included the picture of the error and the info on Download mode, links for files I refer to also at the bottom.

Bump.
I have the same problem "custom binary (RECOVERY) blocked due to remaining installment balance", when trying to install TWRP, in my case I want to install Custom Rom and I could not, I have not found any solution to this problem, I do not have OEM on 8.0, and the RMM status is normal, I could unlock unlock SIM thanks to a friend with Z3X tool, do not charge for it but thankfully I made a donation for the hard work and also that the Z3X is not cheap at all, if you need to talk to him, you inform me to give you his contact.

Flash S10+ to get latest security patches

Hi there, new member with a first question.
I bought an S10+ (SM-G975U) online, unlocked, to be used mainly with AT&T when in US, and different carriers when traveling. IMEA check shows the phone was originally on Verizon carrier, but works fine with AT&T sim card. However, it's not receiving OTA software updates, and the security patches are way behind. When I try to force software updates, says it's already up to date. Seems like on unlocked phones, or switched carriers the updates don't happen. I tried booting the phone with a working Verizon sim card, still no updates. Online searches say that flashing the firmware is my best (or only) option. I downloaded Odin, but I still have a lot to learn and don't want to brick my phone. I'm not sure which firmware version to get. AT&T vs Verizon? U or U1 since it's unlocked? Do I flash all 5 files or just some of them?
Thanks.

A small Update Issue on the Note 10+ 5G Verizon Help?

Hello everyone, this is my first post here.
I have a slight problem. I have an unlocked verizon Note 10+ 5G SM-976V and I changed CSC to GCF a while back because the verizon CSC had bloatware.
Now i have GCF/GCF/VZW. Im stuck on March 1 2020 security patch. The phone works great and everything is working well. I want to upgrade to android 11. That is somewhat not possible because when i try to upgrade from my phone it says, 'Your current software version isnt supported. Visit a service center.'
What firmware is for me? How can i get an firmware that can fix my usual updates? Or if i have upgrade firmware on odin, what version should i be choosing?
I do not live in the US anymore, phone was unlocked on verizon. All sims seem to be working on it. Attaching the files necessary for your study. Please help?

Have a look here for official ota updates from Verizon: https://www.verizon.com/support/samsung-galaxy-note-10-plus-5g-update/
If it does not work and you have an unlocked bootloader, you can flash latest stock firmware with Odin on pc.
