Help Guys!
I know I am a dumb f**k but I accidently flashed xt1789-01 Firmware on my 04 Model.
I have IMEI and everything showing on my phone.
But my Sim isn't working for weird reasons. (It says the sim card isn't compatible with Verizon)
I wanna revert back to Att but it isn't as easy as upgrading to Pie on my Att z2 force.
It won't letme flash Att back on my att phone. It says wrong firmware (lmfao?).
I guess it says this because of the last update on att model was Oreo 8.1.
And the last one on Verizon was 9.0.

Hi, I hope this isnt a dumb question but I've searched and can find an answer. I have an unlocked att s5 running on tmobile network and want to know how I can update from 4.4.2 to 4.4.4 i have checked the software update on the phone and it says Up to date. I have also tried Kies3 and it says the same. My question is how do I update to 4.4.4. do i need a att sim card?

I believe this thread will be helpful. http://forum.xda-developers.com/att...to-root-g900aucu2aoa1-4-4-4-2-3-2015-t3021120
I am staying on 4.4.2 until 5.0 comes out but I would assume since its still the g900A you will always have to keep up with the AT&T updates like this since you can't take an OTA.
hi friends, i need your help again, i have in my hands one galaxy s6 tmobile but one person install android 6.0.1 in this phone, i see one metod, installing one update of one samsung galaxy s6 of metropcs, but this metod no work in this phone, i can dowgrade to android 5.0.1?? or i can istall cwm in this phone?? any help thanks
Try using the new Cellular South firmware thats out and flash it on the phone, its 6.0.1 MM. Go to Sammobile to download.
Oh man, I've been waiting for this firmware! I had a TXAR phone that I flashed the T-Mobile version to, and surprise(!), it locked my previously unlocked phone.
I use Net10 for prepaid service, and they use both sets of towers, so it was easy to switch sims, but I want to put an ATT sim back in for better coverage.
Thanks for letting me know about this.

Hi all,
I bought the Galaxy S6 from AT&T when it came out, but switched over to T-Mobile from AT&T last year. Because of this, I have been unable to get any updates and have been stuck on Android 6.0 when the current release is android 7.0, so I've been thinking of flashing my phone. I was curious as to whether I'm able to flash my G920A with Tmobile's G920T rom? Would it work? And if so, after I flash it, would I be able to receive updates normally from T-mobile's servers, as I'm currently using a T-mobile sim, or would I have to flash every subsequent update?
Thanks
Doubtful, since AT&T has a locked bootloader. If the bootloader was unlocked you might be able to try.

You cannot flash a G920T firmware on a G920A. First off, Odin won't let you because the G920T firmware is only signed to be flashed on the G920T.
And even if you somehow rooted and used FlashFire to force the firmware onto your device, the firmware would brick the device, and without a USB jig or SD card port, the brick would be permanent.

I too am seeking answers on this as I have an SM-920A I brought over to t-mobile. Unlocked the phone, installed the t-mobile SIM and the phone works fine, except, it still has all the old ATT apps I no longer need or desire to be there AND without the T-Mobile apps installed, I cannot use their LTE Signal Booster. Is there any way I can install these t-mobile apps that would have come with the SM-920T load?

Just do this and remove the AT&T apps you don't want completely.

So, what can be done -- if anything--to solve this issue?

Hello,
I have some noob questions to ask before trying this out on my G920T (Baseband version: G920TUVS6FRC1 - which is running Android 7.0). Here's a little bit of background about my situation, I was with Tmobile Prepaid up until the end of December 2019. I ended up getting my phone unlocked by Tmobile and transferred my number to an AT&T Prepaid account.
I was looking to try and get HD Voice/wifi calling working on my unlocked G920T. My question is, when flashing different carrier firmwares, does it matter what the storage capacity of the phone is? Would I be able to flash G920A firmware (no matter if it came from a 32GB Samsung S6, or 128GB (not sure if AT&T ever had a 128GB version of this phone)?
Also I read that it is better to use the princecomsy (my apologies if I messed up on the name) version of Odin rather than the non-cracked versions. Is that correct?
Would I be able to flash different carrier firmwares regardless if my bootloader is locked?
Thank you to anyone that can help.
I'm currently living in Japan, but will be moving back to the US in a couple months, so I recently bought a refurbished Galaxy S20 FE 5g that claimed to be unlocked from the US and had it shipped to Japan.
It works fine with my Japanese sim, but came with AT&T bloatware installed and the model number is still SM-G781U. To my understanding, an unlocked phone should have a '1' after this, signifying that it's unlocked. Because of this, I don't get OTA updated and am still stick on Android 10 and One UI 2.5. So I figured I'd learn how to flash it and do that. It says the CSC is G781UOYN1ATIG, but then when I go to Service Provider it says ATT/ATT/ATT.
Could I just flash the firmware for the SM-G781U1, CSC: XAA onto it and be able to have a fully unlocked and updated phone? Sorry I'm a bit new to this and don't want to brick my phone. Thanks!
I did the opposite (from SM-G781U1 to SM-G781U) and worked with no problems. I needed ATT Wi-Fi calling that worked only with the ATT firmware when I was on Android 10. I suggest to do a factory reset when switching between branded and unbranded but (in theory) you should keep your phone data if you flash the HOME_CSC file.
