Hi all.
I have one of the AT&T Atrix phones, and was wondering whether, when my local carrier (Telstra) bring out their own branded version, it will be possible to install the Telstra firmware over the AT&T one. Perhaps when they bring out the update to 2.3?
I know the bootloader will only allow signed firmware, but I'm wondering whether they also check whether you're trying to install firmware from a different carrier or not. If not, it could be a way to get both localised features as well as remove some of the AT&T restrictions.
Any thoughts?
For anyone interested, it turns out that this is possible to do (but may cause reception issues because their firmware will be for the international version of the Atrix, which has different radio capabilities).
Thanks for the info. I was wondering the same thing. Could you keep us informed if you hear anything else?
I'm buying the Atrix tomorrow.
here is what i need to know
I'm paying retail $499 so i can not afford to brick my phone
so need help avoiding this
1) i am unlocking the phone to put on my T-Mobile pre-paid account
what flash and mods will hurt me if i use them ?
2) are there any OTA updates i need to avoid because i will mod this phone OR it will be of no use to me !
3) what is deodexed and do i need it ? (says AT&T only does this mean an AT&T phone or AT&T service (IE: no unlocked phones running on T-Mobiles network?)
thanks
Rick H. (A1yet)
anyone ?
anyone got ANY answers for any of the questions ?
i need to head out in an hour
Hi! I have been here a while now and i think this is my firs post....
Well... I got an Atrix that is unlocked and has the a custom rom and i would like to know if this is the international model or the At&t one ( i would not like to brick it doing something i shouldnt do)
Is there any way to find out??
If i Code:
su
cat /proc/cmdline
i get :tegrapart=mbr:1100:100:800,kpanic:2500:400:800:
What else i can check??
Thanks in advance!!!
Search reveals that most likely it's an international phone:

Hi SSPA!!! What should i get if it was an AT&T??
mine is an AT&T and I saw this:
tegrapart=mbr:d00:100:800,kpanic:2100:400:800
but the same string could be found on international phones too, as the thread above shows.
Actually I found mbr:1100 could be found on AT&T phone too. So it's not a reliable way to identify the source of your phone.
ok thanks!
I was wondering if anyone else has this variant of the G5, as I have never seen it in any other XDA threads. I got this variant from C Spire (aka Cell South). If anyone else owns this variant, it would be nice to know if there have been any developments with unlocking the bootloader, or if it will work with the T-Mobile unlock (since cspire just piggybacks off of other carriers).
Thanks,
systemCTL
I have this model as well..
I got it about 2 weeks ago from cspire. I would be afraid to try the tmobile unlock on it..my luck it will brick the phone.

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!
