I have sim unlocked my at&t S4. Should I get the OTA 4.3 update from at&t? Go for it or conflicts will occur?
Gratitude :highfive:
The update won't re-lock your phone if that's what your asking.

Verizon phones come unlocked. They have a locked bootloader that limits the ROMs you can use, but you won't lock the phone. You will lose root if it's rooted, but in that case, you can use a rooted 5.0 ROM instead of OTA.
I have an unlocked AT&T_ S5 with a T-Mobile SIM card. I want to update to lollipop and my phone won't update automatically through my settings so I suppose I gotta d/l and update but which update do i d/l? AT&T or T-Mobile?
The at&t s5 (SM-G900A) variant has locked bootloaders, meaning you can't flash any other ROM's besides the stock att rom, unlike the rest of the T-Mobile or other s5 variant communities do. At&t hasn't released the lollipop update yet, and they released an OTA update, still KitKat, recently. So head on over to the att section of the forum and you will see there is a safe strap method available, but I haven't personally tried it.
I have a AT&T Samsung Galaxy S4 (Unlocked) and I am currently using it on Cricket wireless. The phone is currently running on Android 4.4.3 and I would like to update the same to Lollipop. Samsung Galaxy S4 got Lollipop rolled out by AT&T recently but I was not able to get the same since I switched carriers.
Now what is the best way to update the phone. If possible I don't want to root the phone. I went to best buy local store but they were not able to do the same as they said the phone is unlocked. Please let me know how I can update my phone to the latest version. It will be really helpful if someone can point me in the right direction.
Thanks all in advance for the help.
Will putting a AT&T sim in my phone help with the OTA? In the sense if I get an AT&T sim card from someone or purchase one and put it in to my phone will that help with the OTA? I am not sure if this phone was unlocked by AT&T.
I was able to successfully install the updates on my phone. I was able to downgrade my phone by installing stock 4.4.2 using ODIN and then was able to upgrade my device to 4.4.4 first and then update to 5.0.1 via OTA. It was an easy process and the instructions in the ODIN thread was really helpful.
Similar situation
I too have an unlocked SGH-I337 that is unlocked from AT&T and I'm using it on T-Mobile. How did you perform the Lollipop update without an AT&T SIM? I took mine to the Samsung experience at Best Buy and they weren't able to do it via Kies and they believe it's because it's unlocked. Nothing else has been done to it, just the AT&T unlock so that I could switch carriers.
Thanks in advance,

Hi,
I'm a little confused here. I want to upgrade my firmware on an unlocked S8 I bought SM-G950U and it's currently running G950USQS2BQL1 which is VZW FW but I have att as a provider.
To update my firmware do I flash VZW FW or can I flash ATT FW? If I'm able to flash ATT will updates be pushed OTC from now on? Also is there a way to upgrade without wiping the data? Lastly, can I update straight to Oreo (one again without losing data?) The OTA function never provides any updates.
Thanks.

Flash the US XAA firmware and you will get rid of all the carrier bloat and get updates straight from Samsung servers.
If the S8 is unlocked then you can just pop in the Verizon sim and it'll ask to reboot and then you'll have the ATT FW.

Okay, so I need a Verizon SIM to update the device?

What month security patch are you on? If its the November or later it should switch to an ATT S8 after it asks you to reboot. If its earlier then yea you'll be a verizon(doesn't have to be active) sim to get it to take the OTAs to being you speed, and then it'll change to an ATT S8 after asking for a reboot.
Edit: You don't have to flash a different carrier version, it'll change itself on the newer FWs to match whatever sim is in the phone.
