Hi guys. I got my Samsung Galaxy SII on a T-Mobile contract when it first came out. Unfortunately I got into a bit of a dispute with them and left, and am therefore unable to get my unlock code.
So I rooted my phone and unlocked it and the phone worked fine for a few months. Then all of a sudden I lost my signal EVERYWHERE.
So I tried messing around installing a few roms trying to get my phone's signal back. And may have possibly corrupted my EFS also.
I know (using various guides) how to get my EFS and everything back. However I have no idea which rom to choose.
My phone came from T-Mobile, but I am now on a Three contract. So which carrier do I select when getting the stock rom?
Also CSC? Modem? There are several variants of the stock rom it seems and I have no idea which one to pick!
Sorry if I have missed something, this is my first post. I scoured the website for a good 20mins and couldn't find anything that would help with my particular problem.
Info:
Current Network: 3
Country: UK
Phone: Galaxy S2 I9100
Thanks in advance.

Hi guys, just thought I'd update.
Luckily I remembered one of my family has the exact same phone that was on the same contract. So I typed in *#1234# and boom, I had the correct PDA, PHONE and CSC.
Thanks for the links also. Really helped
After giving up on rooting my AT&T phone well over a year ago this week I just found out rooting was available. Right now I am leaving AT&T and going over to T-mobile. I would like to get all the AT&T software off my phone since I will be with T-Mobile.
In searching for rooting ( I have not done it since my HTC One) I see rooting for 5.1 and 6.0. Right now my phone is running 7.0. Can you root with 7.0 running?
When flashing a Rom do I have to find ones that are specific to G925A?
Thanks for any help confirming this. I just do not want to brick this phone. First time I do things like this I want to make sure I have all my information correct.

So your just switching carriers to T-Mobile? And your using the same phone G925A?
It still has a locked bootloader so it's still not rootable. From what I can find you can root 6.0.1 on an older firmware with ENG boot firmware. But not for 7.0.
@ThatAngryGnome
i need G925AUCS7ERC1 7.0 root file
HI, I switched carriers yesterday and my S9+ still appears to be on AT&T software. Is there a guide somewhere that shows you in detail how to get the T-Mobile software on it? I'm not very knowledgeable in flashing, but have seen around the site that ODIN is a solution? Thanks
edit: I know i need to get from U to U1 back to U i'm just not sure how
How do I permanently remove the AT&T logo and bloat? [Galaxy S9+ AT&T Model SM-G965U]
MODEL: Galaxy S9+ AT&T SM-G965U
This is the first time using android, I'm from iPhone. Recently got an S9+ from the used section of Amazon and want to remove all of the AT&T bloat since I'm on Tmobile anyway and it's so tacky. Is there a good guide on how to do this? Can someone help me get started? Thanks.

You can cross-flash the device using modded or patched ODIN to convert your S9 Plus to U1 first after fully wiping, then flashing it to the T-Mobile firmware if you happen to want all of the T-Mobile bloat. If not, then just flash to U1. There are plenty of instructions with links on how to do so around here.
I've found a lot of different tutorials but not sure which one to trust exactly. I'm new to Android and don't want to brick my phone so is there a good detailed tutorial for this?

Hello, looking for some help to see if anyone can help me find the firmware of my A526U specifically for AT&T? I have moved my phone over from TMobile where I purchased it from, and am looking to re-flash it to AT&T. Was working fine for a few months, now I'm no longer able to make or receive calls.
After inserting the new AT&T SIM card, the TMobile splash screen still shows up. The Service Provider software version reflects TMobile still as well and I'm concerned that for whatever reason the phone did not fully update after inserting the new SIM. I spent 2 hours on the phone with AT&T support after the store said they couldn't help me. Pulled the SIM card out, restarted phone, put it back in, reset network settings etc. I've searched sammobile and I cannot find the AT&T firmware, only TMobile, Sprint, and TMK. I would sincerely be greateful please if anyone could help me by pointing me in the right direction for the firmware for this model phone.
AT&T doesn't make their firmware available publicly - for any device. I have a source who can get me Samsung firmware for any USA device - even AT&T. But he charges me for each one
I appreciate the quick response! Is there any option I have here? Could I try flashing a "U1" firmware to his phone then? He's currently on A526USQS4CVA6. I actually found your other post as I was also working on my note 10 plus - https://forum.xda-developers.com/t/n975u-and-n975u1-firmware-links-here.3957648/. If I'm reading that correctly, I should be able to correct? If so, how can I tell if the version I'm downloading is "downgrading the bootloader"

1. Yes, you can try flashing U1 if you want
2. You can't "downgrade the bootloader" - Odin won't let you.
3. In A526USQS4CVA6, "4" is the position of the bootloader level/revision/binary. Make sure that whatever U1 firmware you download also has a 4 in that spot and you'll be fine. (Or just get the firmware from Frija or one of the other similar firmware download tools, because those throw you whatever the newest version is automatically)

Thank you very much sir! I shall give this a go this weekend! You guys rock!
My AT&T N10+ N975U is running on Pie. It transitioned seamlessly with no changes made on my end. It was already using 4G VoLTE though. Same sim card.
I would contact AT&T advanced tech support as there may be an easier way.
4G VoLTE needs to be enabled in hidden settings.

Your AT&T phone? So it's originally an AT&T model that you're still using with them? That's not the same situation that the OP is in

The U is the AT&T variant vs the U1 which is the unlocked variant, correct?

Yup. But OP has a T-Mobile model that they moved to AT&T. There's also no guarantee that a Note 10+ will work the exact same way as an A52. You're also running 3 year old firmware, while OP is fully updated.
So i don't see the correlation.

The old firmware works fine on 4G VoLTE... that's likely not the issue. What is the issue is it wasn't running on 4G VoLTE so it's likely the settings and sim card need updating not the firmware.
Hi All, thought I would provide an update... After spending hours on the phone with AT&T support this week and being frustrated with the AT&T store, I decided to proceed forward with flashing the U1 version. What started this all was last week my son could no longer make or receive calls on his AT&T A52 phone (we ported it from TMobile September 2021). The store and AT&T advanced tech support said there were issues with people's BYOD devices, even though the A526U and A526U1 shows on the supported devices list. The store rep said he's been getting people in left and right that can't make or receive calls, and all they can do is upsell customers to an AT&T branded phone.
SO... my son's phone was on A526USQS4CVA6. Startup screen showed TMobile still, even with the AT&T SIM card in it. I proceed to flash the A526U1OYM4CVB2_ATT that I found from Sammobile. Was hoping someone had just the "U" version but I couldn't find this anywhere. When doing the flash, I used the Home_CSC file (I had to download a patched version of ODIN as it was stuck as setting up connection) and when it finished it would just keep going back to the download screen on the phone and I freaked out. I did some more research and decided to flash again using CSC instead of Home.CSC (I did a backup using smart switch on my PC luckily). This WORKED! I'm guessing because the software version he was on was different than what I was trying to flash too so maybe this is why I needed the CSC for a clean flash (there was no user data file that downloaded from SAMMOBILE).
Now, calls are working on my son's phone again! AND his service provider software version now reflects ATT vs TMB! Man this has been one heck of a journey lol. I've seen numerous forums on google of people having the same trouble with me, their BYOD devices not working. Seems a flash of U1 worked for me, so hopefully this helps others out there!
